This is demonstrative of the advantages of the new low-level APIs being added to JavaScript to work efficiently with binary data.

Fabrice uses this to implement an x86 interpreter -- it could not be done efficiently without typed arrays. However, it is still slow -- imagine what kind of advances could be made if a common bytecode was established that would be JIT'd by the JavaScript VM, and could be output directly by the emulator.

This is why so many people want to see the browser execution environment offer more complete, low-level APIs instead of high-level APIs locked to HTML/CSS and legacy browser technology. Efficiently supporting high-performance, high-complexity systems such as an x86 emulator (or a video game, or custom font rendering, or even an application framework) absolutely require efficient low-level APIs.

After FFmpeg (used in all your TVs and gadgets, very likely), QEmu (used also by Xen and VBox and other), tcc and his IOCC entries, the DVB-T emission with an ATI card, Fabrice comes, once again with something crazy...

He is really impressive...

I'm utterly dumbfounded. Not only does it boot, it's got emacs, and a compiler.

  Welcome to JS/Linux  
~ # emacs test.c
~ # cat test.c
void main(void) {
printf("Hello World!\n");
}
~ # tcc test.c -o hello
~ # ./hello
Hello World!

[Edit: just realized that there is already a 'hello.c' in the directory that shows just this with better diction.]

Fabrice is one of my all time favorite software engineers. Reading his code, studying his methodologies and learning by copying has been a long time task for me.

My first encounter with his code was QEmu, when it was required to run the XO OLPC linux images. Society truly benefits when people like him are devoted in support of open source software.

I admire Fabrice a lot, he is a programming hero for me. However it is not true that he is not interested in money, for instance the QEMU module performing the run-time code translation to go fast was not released for free in order to earn from this. I don't know if he managed to earn or not from QEMU in the end, but IMHO that of selling the module to final user was not the right strategy, when QEMU was started and became famous, "virtualization" was an huge buzz and interest for many companies, so many ways to make money from this.

Also this new code is not released under a free license, so by default as far he is not sure what he's going to do with the code the "open source way" is not the default. This is not a critique. I think Fabrice Bellard is a genius, but as an observer he seems interested in making a profit from his work like many other programmers.

Instead subjectively I've to admit today I no longer consider the GPL a completely free license, but this is another matter and may be related not to earning but to the meaning "free software" has for you. For me it is as simple as letting people to do everything with your code. IMHO the BSD license turns out to be better both for users AND for you to earn from your product later.

This is completely awesome. When I saw http://cb.vu a few years ago I thought hey, someone has finally done it, but that turned out to be a hack. Kudos to Bellard once again.

Nitpicking: the terminal emulation is messed up. It keeps resizing horizontally, and less gets confused. I'm sure the terminal emulator was fun to play with. A correct vt100 state machine implementation [1] would probably not be quite as fun [2]. There's a vt100.js library used by a couple projects that might improve things. [3]

Unbelievable, this is like magic. I am totally impressed. It is a real linux instance. BTW. I see the hello.c file someone mentioned here. Have we all mounted the same disk image?

I see so many use cases for this, but I don't fully understand what is going on behind the scenes. Maybe someone can shed some light on it:

  1) How is the disk emulated. Is it a local image, or is it running on the backend?

2) Is there a remote possibility to get the networking up and running?

3) Can the disk image be externally accessed to be customized?

double ay = f.read();
double az = f.read();

Neat. You can mount sysfs like so:

  # mkdir /sys; mount -t sysfs /sys /sys

That would allow you to look at the emulated hardware that is present.
Looks like only virtual devices are present -- ram, loopback network etc.

Makes sense to me. The MVP here is cpu emulation.

The page was near-unreadable for me because the CSS uses the font stack "courier,fixed,swiss,sans-serif", and courier is just too thin and wispy against a black background. I opened Firebug and changed the CSS declaration to be "monospace" and then all was right with the world.

That said, it's a phenomenal achievement, and should be a great way for websites to demonstrate command-line tools to people. :)

(also: browsers let you store more information with DOM Local Storage than you could in a cookie; If you could expose that to Linux as a block device...)

TermKit - a graphical terminal replacement acko.net

telemachos 4 days ago  replies      
After seeing something about this yesterday, I said on Rstat.us/Twitter that I thought it was pretty but disagreed with the whole premise. I still do, I think, but I'm very impressed with how reasonable Steven's response was. He wrote me and asked pretty much "Why?" I said essentially "Unix philosophy" and attached the link that ended up in his blog post.[1] He wrote back and at some point he wrote this post, probably replying to all the people who were taking snipes at him. So this is a long way around to say, kudos for being gracious and serious in the face of people glibly writing off your hard work.

Having said that, I'm still not sold on the concept - yet. I've played with it a bit this morning. Obviously it's still pretty alpha (more than one seize up or crash), but that's fine. My larger problem is in figuring out how it would fit into my daily work flow. After trying it out now, here are some concrete issues:

+ No monospace fonts for code. The output of cat looks like teeny-tiny website font. Things are no longer "lined up". That's bad.

+ I can't use any applications that take over the terminal (irssi, mutt, vim, less). Steven says as much - it's not part of his design - but for me it's a big problem. It means that even if I embrace TermKit, I still need those 1980s terminals.

+ No scripting language built in. As bad as shell scripting might be, I get an absolute ton done with it. I don't want to give that up unless something will make up for all that "getting shit done".[2]

+ TermKit (maybe?) forces me to change habits I can't afford to lose. One small, but I think important, example: If you try to run this:

    awk '{print $1}' file.txt

TermKit doesn't echo the single quotes. That is, you can type them, but they don't show up on the screen. I'm not really sure what to do with that. Does that mean I should stop typing them? Does that mean that I still must type them, but TermKit strips them because they aren't pretty? Does TermKit allow me to do it either way? I'm going to need to remember how to quote things when I log into a remote machine over ssh, so if TermKit will force me to change habits, that's a big, big problem. (After a few experiments, it seems like the single quotes are still required. Without them, TermKit tokenizes the stream differently. If that's the case, why refuse to echo them to the screen?)

It's funny, his 'ls' by default prints out an information-sparse grid of icons (only showing 10 items with a horizontal scrollbar?), whereas when I use the command-line, I'm looking for exactly the opposite of a GUI - an information-dense table of text. I agree with the commenter that -r-xr-xr-x - or even 0555 - is far better than "you can't touch this" (which doesn't describe who can't touch it, and in what ways). His "rich display" is actually a display of poverty - it conveys less information than text.

The typing of file / stream data is interesting, but I don't think it's realistic - it requires all tools to change virtually overnight to preserve the headers. And it's not enough just to preserve headers; what if you pump stuff out to a temporary file and read it in a few milliseconds later? What about compound files, with data chopped out of them? If you want pretty pictures, syntax highlighting etc., ISTM better to have an enriched terminal communication protocol along with a couple of viewer programs which can render data formats to it, rather than change the whole world to type every data flow everywhere.

moe 4 days ago 1 reply      
I love this!

It has fundamental conceptional flaws. But hell, finally someone is rethinking the terminal, please continue working on this!

Here's the direction I would propose:

It must be 100% backwards compatible. This is not optional, anything else is a non-starter. Likewise trying to re-invent the entire unix userspace toolchain is a terrible idea.

So why not do it the UNIX-way and how terminals have always done it:

Start by emulating a normal terminal (xterm/vt10x). Add support for a special ESC-sequence that switches the terminal into TermKit mode (and another one to switch back).

This way we have a normal terminal, with a bonus-mode.

A simple cli-wrapper could be provided to mix the "magic" in. E.g. to cat a PNG I would: 'cat foo.png | tk_wrap'.

And on the screen that image would magically be embedded below my command line, just like any text output would.

tk_wrap would be small wrapper that first emits the termkit-esc, then the stdin-data (converted to the json meta-format), and finally the termkit-end-esc.

That's the basic architecture that I'd like to see. And from there, sky's the limit.

JunkDNA 3 days ago 0 replies      
I'd like to offer a slightly different perspective on this. As someone who is a hybrid hacker/biologist, I welcome something like TermKit. I have invested a good chunk of time learning unix commands and the shell because lots of scientific applications require it. Furthermore, as a data wrangler, the unix tools are a necessity for quickly processing and pumping files around. I require unix to efficiently do my job. I often think, "Gosh, what do all these other people do when they need to do X?" where "X" is some ugly task that I can hack some grep and sed commands together to accomplish. I don't think most programmers understand the sheer number of exceptionally well-educated, genuinely smart people who spend huge chunks of their day doing menial "copy/paste" in Excel (because it's the only real tool they can use) when they should be designing bridges, curing diseases, analyzing data, etc...

If you're a unix sysadmin or a full-time hacker, you can justify the cost in time and effort of learning and memorizing all this stuff. In fact, you'd be foolish not to. But there are a lot of people who don't spend all day in a terminal. Nevertheless, they frequently need the unix terminal to get something done. A tool like TermKit could be a huge boost for those people allowing them to bootstrap their knowledge without having to dive into the deep end all at once.

There are legions of people out there who are smart enough to learn some bits of unix if only the learning curve wasn't a sheer brick wall. If you need evidence that man pages and "-h" don't cut it, start typing common unix commands into google (xargs, tar, grep, etc...) and you'll almost always find one of the top suggestions is "command_name examples" or something like that. Why is that? My grandma isn't trying to use "xargs" I assure you. Someone with enough knowledge of the unix command prompt to know they need xargs reads a man page and they still don't know how the hell to use the command properly. That's a usability problem and there are modern ways to help with it (as is demonstrated by all the things IDE's do to help programmers all the time).

I'm really excited to see where this goes. There are all sorts of possibilities it opens up.

ChuckMcM 4 days ago 1 reply      
Excellent exploration of alternatives to the old 'terminal' application. It would probably help for context to explore the Bell Labs 'BLIT' terminal and the Digital Equipment Corp VT340 (color graphic terminal) and the Tektronix 4010/4014/4064 terminals. These had capabilities that augumented the basic terminal stuff and made it prettier at least to use them.

The humorous thing for me is seeing the discussion which essentially devolves into creating a new windows type metaphor but with a lot of keyboard shortcuts.

It may sound pedantic but consider that the terminal is the terminal because terminals define a keyboard driven user interface. A user interface is a 'vocabulary' which describes actions. Its vocabulary scales from a communication channel that is 300 baud to one which has multi-megabaud connectivity. You can create a different vocabulary (which is what the other terminals above did) and get additional features.

And you can create an entirely new vocabulary if you're willing to change the minimum connectivity channel bandwidth as well (I doubt TermKit would work well over 300 baud for example). There was some good work done on this in the 80's with 'visual shells' on the PC and of course there is a ton of work that IBM did in creating optimized terminal environments (with visuals no less) on 3270 terminals which were in many ways a pre-cursor to todays IDE tools, although perhaps more like Eclipse. Their environment which ran airline reservations was a good example of optimizing the vocabulary (key strokes) against the variety of tasks an agent might need to do.

So rather than calling this a graphical terminal replacement (which it isn't) calling it a visual UI which can be driven entirely by the keyboard might be better. I think that fundamentally the "thing" about terminals that everyone sort of 'gets' is that you don't have to use a mouse, you always know where your 'focus' is, and there are millions of key combinations which you can use to express certain actions. For some, that is simply 'living in emacs' for others it could be something like this.

It's a pity that this is so difficult to try. The blog post has so much detail and effort put into it, but all that shine and polish disappears when you try to install it.

Specifically Step 1 of the instructions[1] has a link titled "install node and npm" [2] which has the line 'git clone git://github.com/ry/node.git', which is incorrect. The correct URL (as far as I can tell) would be 'git://github.com/joyent/node.git'.

In addition the linked instructions say nothing of npm, which can be installed quite easily by running 'curl http://npmjs.org/install.sh | sh' as root.

Back to the TermKit instructions again, and step 5 says 'git clone git@github.com:unconed/TermKit.git --recursive', which didn't work for me. What worked was 'git clone git://github.com/unconed/TermKit.git --recursive'.

Finally after all that, I just see 'You cannot use this version of the application TermKit.app with this version of Mac OS X.'. Would have been nice to mention that at the start.

I had a similar idea about 10 years ago, but never got around to implementing it.

I'm amazed at the amount of hatred directed towards this - as if the terminal could in NO WAY be improved?!. But clearly it can. For example - wouldn't it be nice to have a terminal status bar with your CWD / git branch / etc in, without cluttering up space before $? Yep, you can use screen, and that destroys your ability to use the scrollbars.

Or, consider filename completion. Wouldn't it be nice to show the intended completions in a popup as you're typing (like web browsers do) ?

Why, when I do 'ls', can I not drag & drop one of the files to another finder window? Why is the terminal forever isolated?

Why when I run 'mvn install', which generates umpteen bazillion lines of output, can the result not be folded into a single line showing the summary, that I could expand if I wished?

There's lots of scope for this kind of thing. My main concern would be whether a single WebKit control is the right way to go - it'd be nice to, for example, embed custom controls within the shell (but this might also be possible).

So I think it's an awesome idea.

"At the end of the day, Unix just has bad usability"

I have to say I highly disagree with this statement but, I also disagree that there is anything wrong with the classic terminal. I find a full screen terminal with nothing but text as a thing of beauty. They remove all but the most essential details and work on a very simple common format (text).

In a way this kinda makes me think of Windows Power Shell, which is trying to replace the classic shell with a more object oriented shell, it has a lot of good ideas but in ways it brings more complexity to the issue than most Unix users are looking for. Seems like this project could probably take some ideas from Power Shell though.

I certainly have nothing against this guys work but it is not really a classic unix shell replacement and should probably not strive to be such a thing.

Maybe I'm an old fogey but I'll stick with xterm and iterm. Having a terminal where I can have the same experience whether logged into a *nix box, on osx, or sshed into a remote server is far more appealing than being able to cat images or having a pretty progress bar. If I want to make json more readable I can just pipe it through one of the many json formatting scripts.

It might just be me but I find cocoa to be a bit boring and dated looking. Unix terminals are timeless. A nice tiling windows manager with 5 terminals is still one of the most beautiful set ups.

The first thing to realise is that the existing UNIX data processing tools deal fall into two categories - those that process (including generate or consume) an ordered sequence of text records (eg. sort, comm, uniq, awk, sed, grep, tr, cut, find, xargs, ls...) , and those that process arbitrary binary data (cat, dd). Most fall into the first category.

Now, while it might make sense to use a better interchange format than "newline-separated text" for those ordered text records, I don't think that adding other arbitrary data types is particularly useful, unless a way can be found to make these arbitrary data types self-describing. This is because there's little to no commonality in the types of processing that you do on different data types: the article shows the example of "cat termkit.png", but what does it mean to concatenate two images ("cat foo.png bar.gif"), or concatenate an image with a text file? Making some assumptions, we can certainly define arguably useful semantics for those, but what does it mean to "sort" an image?

And how do we write "cat" to deal sensibly with currently unknown data types, that will be defined in the future?

I love the idea of experimenting with graphical output on the console. I've seen images and vidoes running on the terminal (not a terminal emulator) using "framebuffer" consoles.

Sadly that typically only worked in full-screen mode.

If somebody wrote an ordinary terminal emulator that allowed pixel graphics as part of the normal text flow, and created an easy API for programs to use it, I'd be very happy.

TermKit looks cool, but I fear I'm too old-fashioned to move away from ordinary shell in such large steps.

This a cool project, albeit not my cup of tea. Sure, the terminals out there need a little work, but I'm skeptical about bringing too much of the "gui world" in.

There are, however, some concepts that are worth copying and that are in fact doable in current terminal environments. What I would like to see is more innovation in the world of console programs. There are lots of things to do in terms of auto-completion, navigation and integration etc.

I played around with what I think is a very similar idea a while back: https://github.com/ianb/jsshell -- I think the basic architecture is the same, but this is much more advanced; I never really got past the point of displaying all output as literals.

In both cases I think this is really as much a replacement for the shell (e.g., bash) as for the terminal. The truly fundamental verb in a Unix system is executing something with a set of string parameters, an environment, and a cwd, and passing stdin in, with stderr and stdout coming out. That's pretty much everything, so there's a lot of flexibility about how you can present that to a person -- all the stuff like &, if statements, file redirection, shell quoting, etc., is part of the shell UI, it isn't really core to the OS or any of the commands.

There's a lot of graphics and icons in this particular implementation, but IMHO that's not really the important part. Taking out the statefulness of the shell is the more interesting part to me. "cd" seems magic, but it's just setting an internal variable in the shell. Foreground and background processes seem core, but they are just a way of handling the inability for a terminal to handle more than one thing at once. Variable substitution, redirection, backticks... these are all abstractions; and they are useful abstractions, but they might deserve a bit of rethinking.

This has a lot of great ideas, and I like the idea of an enhanced terminal in general, but I think it goes too far. Having to reimplement a large number of commands to support this concept of separate view and data streams is complex.

A few ideas I'd like to see integrated into an existing shell/terminal in a backwards compatible way:

* Syntax highlighting/tokenization of the command as you type. Show the different parts of the command you're typing: the executable, the arguments, the pipes, the IO redirects, shell constructs like loops and conditionals, quoted strings.

* Maybe command-specific syntax awareness like highlighting the flags and file arguments differently, regular expressions for sed/grep, awk syntax, etc. This would require descriptors for each command, similar to how autocomplete works?

* Enhanced output formatting, like the clickable paths, displayable images, etc. But rather than modifying/rewriting the program, have a way to describe how to display the output of certain commands. The shell should be able to figure out what the final command in a pipeline is, right?

* Detect and display binary file formats based on the content rather than the filename so support existing commands.

I find Unix usability standards generally pretty insane. Funny he should post this, as on the train today I was thinking of making a program I'd call 'SmartTerm' or something which would basically be a more usable, graphically augmented terminal for beginners (or people who just can't stand interfaces which depend on memorization and patience).

Some things I find nuts about the current terminal is OS X (at least the default behaviour) are:

- half the line which you need to write in is taken up by repetitive info like User, Time, and Directory

- put the currend directory somewhere useful like the title bar

- when i start to type a command, give me graphical autocompletion automatically (unless i switch it off), along with a note/tooltip explaining what the command does

- after i've typed command, give me a pane somewhere which explains what all the stupid flag options are and what they do

- give me another pane with an audit trail in plain english of what my commands have accomplished, and then give suggestions on how these could be accomplished using simpler shortcuts (especially in something like Vim. give me some help to learn the shortcuts as i work, FFS. on a GUI you look at the keyboard shortcuts beside the menu items, and get to know them naturally. this would also give you some confirmation that your command worked as expected, rather than just a blank prompt staring back at you

- let me highlight text with shift and arrow keys

None of the examples really sound all that exciting. I see the Unix shell more of a text file manipulation toolkit, so apart from some corner cases I'm not sure if adding MIME types etc really would add much value for the usual tasks. If you're adding too much structure to things, you might as well go all the way and base everything around a programming language or framework (cf. Oberon, Powershell, Lisp Machines).

I agree that emulating a terminal from the late 70s isn't exactly the peak of programming. Character-addressed terminals are just another way to get (cheap) WIMPy GUIs.

Many times you need to look beneath the veneer of abstractions that is the modern GUI, to work with speed and flexibility. However you don't want to strip away all the abstractions. That would yield the system very unwieldy. (example: Programming in C vs Programming in Assembly) The Unix command prompt is just the right amount of abstraction for me, and for many other users.
What the project proposes is certainly novel, and this level of abstraction may work for some people.

The terminal hasn't changed much in 40 years because it very good at what it does, that is, allowing experts to get stuff done. One of the usability lessons of modern computing is that the mouse is a productivity killer. Having transitioned back to vi from TextMate, I have certainly found it to be true.

The author talks about how its a shame to give 2MM pixels to an 80 column terminal, but from what I've seen, developers are perfectly capable opening multiple terminal windows to view things like log files and running quick commands. Try that on a WYSE.

While I don't think I'd ever use this as a replacement for my terminal, I do think the "server" part of the architecture is interesting. What if you built a native OSX app to replace finder. That is something I'd use.

As far as I can tell you have to rewrite all your applications to use this.

This is great, and I wish you all the best of luck, but it looks like you're just rewriting Applescript.

Also, the reason Unix tools don't toss around JSON/XML/MIME is for sheer simplicity. It's a zen thing, something you OSX guys wouldn't understand.

Ironically enough, this reminds me a lot of eshell, the shell implemented in Emacs lisp. Since it runs in a rich environment, it can augment a lot of standard unix functionality with really useful features, and you can extend it in a language that's not insane.

For example, grep/find results are hyperlinked, you can pipe commands directly to buffers (or even lisp functions) rather than just files, and such. In fact, now I'm tempted to add the ability to cat an image and have it display inline; should be pretty easy to implement in elisp.

Can't really say this or that about the project. It looks cool but I have no idea whether the user interface would lessen the friction between myself and the computer; it might just as well increase it.

But that's okay. We're not supposed to decide whether the prototype points to the right direction or not; we're just supposed to rant and ramble a bit about it.

However, the question of whether this turns out to be a good idea will be evident when and if TermKit delivers. In this context it means that TermKit or some of its derivatives turn out to be actually more useful than the standard Unix shell.

The indicator would be that instead of a traditional Unix shell, people start using TermKit in order to get more things done more easily and in shorter time.

This is interesting and a cool proof of concept.
I don't believe that, as you show it, it is something I'd want to live in.

I virtually live in a full-screen emacs (on CLI or GUI). Emacs provides a somewhat nicer shell world than straight up Terminal.app. Emacs has copy & paste, a fully editable window display and its own command history.

Why do I bring this up? Because I feel that your application as currently demoed is not going to help me. I don't want to see GUI icons in general.

What I do like is your connection to the OS display layer. The ability to render out a PDF-inshell is pretty nice. Without having to go grub around for the right configuration, I can't just go "load foo.pdf" and have it pop up automatically.

So I really look forward to see what kind of cool explorations you do.

I've toyed around with similar concepts, but went the way of trying to middle-man the input and display of a standard console instead of trying to recreate one. Admittedly that creates some limitations to how integrated things can look without extra work, but it allows for normal interactive programs and really only enhances what was already there. Plus there's the added benefit of being able to run commands even while something interactive is up.

In any case, these kinds of hybrids are inevitable due to the vast room for improvement that exists in desktop and system apps combined with how powerful the web standards have become for UI and interactivity.

Really though, while I think TermKit is a decently executed attempt at this, it alienates some of its audience for obvious reasons. It completely throws away the charm of a shell with visual style choices and breaks powerful features that people expect. That's fine, because even with those departures it can suffice as a casual mode with certain conveniences for times when it makes sense.

Visual styles can be fixed or customized, so that's just shortsightedness by others.

As far as expected features like interactivity and whatever else people feel TermKit lacks, it seems like any hybrid terminal that takes this route should really try to implement a quickswitch that lets you fade between a rich terminal and a standard text console, already at your working directory with the same permissions.

Sure, people could just task switch to another running console, but that segments the whole experience a bit more.

TermKit could really help unix overcome the problem of discovery.

On the command line it takes extra steps to discover the switches and arguments that a given command presents. It's easy to miss a specific incantation that will bring forth the full power of a given command in a given situation. Git, for example, has an amazingly rich command. It's hard to discover what you can do so most people end up using just the few commands that they absolutely need.

Just as TermKit offers a selectable list of directories when one types a path, it would be great if it could provide a structured way to build commands invocations, that presents options and perhaps help content as you go.

In addition to helping newbies dive in and get stuff done, it would help more experienced users continually advance their knowledge of how to get the most out of the tools they use.

All those mathematicians think that the United States could do much better than it does in teaching elementary mathematics in the public school system. I think so too after living in Taiwan twice in my adult life (January 1982 through February 1985, and December 1998 through July 2001). Taiwan is not the only place where elementary mathematics instruction is better than it is in the United States. Chapter 1: "International Student Achievement in Mathematics" from the TIMSS 2007 study of mathematics achievement in many different countries includes, in Exhibit 1.1 (pages 34 and 35)

http://pirls.bc.edu/timss2007/PDF/T07_M_IR_Chapter1.pdf

a chart of mathematics achievement levels in various countries. Although the United States is above the international average score among the countries surveyed, as we would expect from the level of economic development in the United States, the United States is well below the top country listed, which is Singapore. An average United States student is at the bottom quartile level for Singapore, or from another point of view, a top quartile student in the United States is only at the level of an average student in Singapore. I've been curious about mathematics education in Singapore ever since I heard of these results from an earlier TIMSS sample in the 1990s.

The article "The Singaporean Mathematics Curriculum: Connections to TIMSS"

http://www.merga.net.au/documents/RP182006.pdf

by a Singaporean author explains some of the background to the Singapore math materials and how they approach topics that are foundational for later mathematics study. I am amazed that persons from Singapore in my generation (born in the late 1950s) grew up in a country that was extremely poor (it's hard to remember that about Singapore, but until the 1970s Singapore was definitely part of the Third World) and were educated in a foreign language (the language of schooling in Singapore has long been English, but the home languages of most Singaporeans are south Chinese languages like my wife's native Hokkien or Malay or Indian languages like Tamil) and yet received very thorough instruction in mathematics. I hope that all of us here in the United States can do at least that well in the current generation.

P.S. Another reply mentions the Flynn effect (secular increase in raw scores on IQ tests from generation to generation in most countries worldwide), and links to the Wikipedia article. Thanks for bringing that up. Being aware that the Wikipedia article on that subject has been subject to edit wars that have gone to the Wikipedia Arbitration Committee,

http://en.wikipedia.org/wiki/Wikipedia:Arbitration/Requests/...

I think it may be helpful to link to another source about the Flynn effect

http://cscs.umich.edu/~crshalizi/reviews/flynn-beyond/

that has had the influence of better informed and more impartial editors. There are several good discussions of the Flynn effect in recent books on IQ testing, and citations to those can be found in Wikipedia user space.

I don't think people on HN need more intelligence. After 120 IQ points, it doesn't make much of a difference to winning a Nobel Prize. I think what people need here is an increase in their willpower to see boring stuff through to the end.

The author juxtaposes his recommendations against his unnamed professor's claim that intelligence is genetic and fixed at birth, pointing out that there are broad classes of behaviors that can improve our intelligence -- but he neglects half of the response to his professor's genetic predestination view, namely the whole host of physical/chemical/biological factors impacting both brain development and cognition later in life.

As just an example, I was recently impressed by a study (http://rspb.royalsocietypublishing.org/content/270/1529/2147...) demonstrating improvements on both a memory task and an intelligence task through creatine supplements. The explanation suggested by the authors (and it looks like some other literature as well, though I haven't really dug into it yet) is basically that creatine is part of a mechanism for rapid ATP synthesis, that the ion pumps in your neurons run on ATP, and that if you're sometimes "fuel-limited" (their word) creatine levels matter, in the same way that oxygen and glucose do. This make sense, but I was quite surprised to read this, I think in part because I'm used to seeing my brain as being a relatively static thing. Stepping down a level of abstraction, and thinking about the instant to instant chemical resource needs of individual cells and gates is kind of eye-opening. And for all I know there's hundreds or thousands of other documented effects, where increasing or decreasing the presence of some reagent associated with running ion pumps, or growing axons or synthesizing neurotransmitters has some measurable effect on intelligence.

I take exception to the 'Think Creatively' item. It's kind of like making a to-do list with 'lose 20 lbs' as a line item. Much easier said than done.

That being said, I think one of the best ways to improve your creative thinking is to work directly with other people that YOU consider to be creative thinkers. At my previous job I always enjoyed working with the CEO, sales, and marketing folks because they almost always approached problems from a completely different angle than I would. Experiencing how others ideate is very mind opening and often times humbling.

#4) Do things the hard way. It's hard for me to agree with this. In principle, I want to bemoan the decline of my ability to spell as a result of auto-correct. But I think that casts an unfair negative light on the idea of doing things "the easy way".

Think about math. There is no question that the Arabic numbering system makes doing math easier. Why should I to go back to scratching out base-60 cuneiform? I can challenge myself just as easily by pushing on to more powerful and abstract mathematical concepts made possible by timesavers like the Arabic numbering system.

I'm sure that having access to high-level languages limits my understanding of the bits and bytes. But I can use these new tools of abstraction to do things that I would have found impossible if I were writing machine code. I'm not sure I see the value in doing things the hard way, when my brain will be challenged enough probing the depths of what these new innovations have made possible. I think the author misses one crucial part of intelligence - intelligence, insofar as it is about abstract thought, is positively correlated with the sorts of things I can do without thinking about them.

'#4 Do Things The Hard Way'

I think this is so important for our young generation b/c everybody is trying to "hack" or "game" the system. The problem is that you don't actually internalize things by hacking your way through

So it depends on your goals. Let's take a computer science degree for example: if your goal is to do investment banking and having a CS/engineering degree from a top university really puts you apart from all those econ/business majors in the finance interviews (which it does), sure hack your way through CS/EE: you're not planning to go into that field anyways so copy-change homework and study past tests to hack the system and get a good GPA. But if you're doing CS to be a software engineer, you DON'T want to hack your way through, you'd want to "do things the hard way" and really learn the material.

PDD-NOS " Pervasive Development Disorder Not Otherwise Specified, is not necessarily a mild form of autism. The meaning is in the name. It means that the diagnosed doesn't fit more specific diagnoses such as Kanner's autism or Asperger syndrome.

Even though someone who's autistic fail to show intelligence through a test, I believe they still may be very intelligent and can show this better through training.

I personally still believe reasoning skills can be trained by learning new heuristics at least.

From what I saw, society reserves creativity to artists, writers, composers, and other "creative types". For some reason creativity has become associated with creating useless inventions that no one will ever buy; sometimes people see creative person as a loner who spends days and nights on drugs throwing paint around or mumbling crazily.

In reality, creativity is, perhaps, our only advantage when trying to not get killed by other animals. Picking up a stick and fighting off a larger animal -- great example of creative solution. It's novel.

Before, no one ever thought to pick up a stick. Perhaps sticks were viewed as merely lying there, to be carefully avoided in case somebody steps on one. Maybe those who tried to pick up sticks were viewed as crazy, sinful by some sort of primitive Republicans (not that Republicans now are more evolved :)... I mean, who cares about sticks, animals were usually fighting with their own teeth, hands, or horns (I wish I had a horn).

It's not until an animal with a stick has beaten the shit out of another animal without a stick for calling him crazy, that the sticks became a useful tool.

I mean, face it -- we're just animals, and without creative approaches to our problems we wouldn't be talking about this on a giant electronic mind-network-thing.

"What happened is, a long time ago, the country Belgium took over this country Congo and killed a lot of people and made everyone slaves."

No, that's actually not what happened. First of all, they did not take over Congo because Congo never existed before Leopold drew it up on a map on a rainy Saturday afternoon together with Stanley. Also, the country of Belgium did not take over Congo, it was a private enterprise by king Leopold II, although the government later took it over from him after reports of atrocities started to trickle through to western Europe. Third, they didn't make people slaves. The slave traders operating in Congo were mostly African-Arabic. The Belgians levied taxes on the population. This was first collected in rubber, and the colonist but also the Congolese army committed atrocities such as the cutting off of hands, murder of village elders, and so on to maximize production. Many more lives were claimed by the sleeping disease. Later on they switched to taxing in money which meant that many young men had to work in the mines to earn money for their village, often under really bad conditions. The wars, dictatorships, and genocides started after the independence.

Don't get me wrong, I'm not making excuses here or anything, but it irks me when people reduce the complex history of a beautiful country to an overly simplified and plainly false representation of the facts.

At risk of taking an unpopular devils-advocate position:

I think that the principle of patents is okay. Invest time and money developing an idea, with a guarantee of exclusivity on executing on that idea in the marketplace for a period of time. It encourages a level of risk taking for "getting there first".

Software patents aren't any different in many respects because somebody has to go through the time and effort to actually come up with the idea.

The problem that software patents face is that, while many of the ideas are new and innovative to non-software people, software people tend to groan about seemingly obvious amalgamation of common software techniques into another idea. But really, most patents (non-software) are the same:

Cooking an egg with an electric heater http://www.google.com/patents?id=RgcEAAAAEBAJ&printsec=a...

Glasses for a chicken http://www.google.com/patents?id=M5BGAAAAEBAJ&printsec=a...

Making water hot with the sun http://www.google.com/patents?id=YBwrAAAAEBAJ&printsec=a...

Resoling a shoe http://www.google.com/patents?id=895CAAAAEBAJ&printsec=a...

Keeping paper dry http://www.google.com/patents?id=7IBqAAAAEBAJ&printsec=a...

That was 60 seconds of searching the patent database of common sense ideas. Clearly obviousness is not much of a threshold in patents, software or otherwise.

Perhaps a better way to think of software patents is not "obvious ideas" but "soon to be obvious ideas". In my experience, most software patents become blindingly obvious after the fact, but if they were so obvious beforehand, somebody would have:

a) implemented it into a working system (prior art)

b) patented it themselves first

Our principle problem is that the world of software moves breathtakingly fast, and keeping soon-to-be-obvious ideas locked away for a long time can seem ridiculous. But make no mistake, even implementing some obvious ideas can be the investment of millions of dollars in R&D.

For example, a system integrator I know of had an IR&D program that spent $130 million dollars just in the R&D phase for what amounts to off-the-shelf software, installed on a few VMs, on rackmounted servers, in a large plastic shippable box with a few perl scripts and cron jobs hacked together to shuttle data between the COTS software and an Oracle database running in one of the VMs. Obvious? Perhaps. But nobody had gone through the trouble to actually do it, and spending that kind of overhead was a significant risk.

Should they own this idea for the next decade or so? Probably not, but how about the next 12-24 months? At least long enough so that they get a head start against competitors who didn't get there first.

I do think the patent system is need of serious reform w/r to getting rid of patents with prior art. Fighting a bad patent can be more expensive than getting one in the first place. And software patents are too frequently granted in cases where there is obvious prior art, common algorithms for example.

If we really want to fight software patents of obvious ideas, or permutations of obvious ideas, perhaps somebody should write a tool that simply combine every obvious idea in software into some greater system, then documents it all thus creating prior art that stops all of these so called bad patents...and then patent the "prior art permuter". In other words, if the ideas are obvious, a piece of software that does this should be buildable. I call this the "obviousness of software patents theorem".

I think the worst practical thing about software patents is that they create uncertainty. If there is one thing that is universally abhorred in the business world, it is uncertainty.

There needs to be a fast, cheap, reliable method by which small businesses can determine whether they are affected by anyone else's patent rights, and if so, by whose and to what extent. This way they can enter useful negotiations and adjust or abandon their plans as appropriate if patents are involved, or they can build their business free of unknown liability otherwise.

Given that I can see no viable means of ever constructing such a system, I don't see how patents or any similar legal tools will ever be anything but a tool for those with vast resources to crush competitors with few resources through means other than fair competition in the market.

This is one of those issues that I feel is more a member of tribal affiliation than anything substantive. It's like flag burning for us Republicans: if I were to rank order my political objectives, "prevent flag burning" would be somewhere in the x0,000s, but the tribe cares about this a lot for philosophical reasons (which I'm broadly speaking on board with) and as a result uses it as a signaling mechanism.

Software patents strikes me as signaling for geeks, or the techno-libertarian-esque streak that is pretty common in the community at any rate. Is it an important issue? Well, yeah, I'd love to see it addressed. Someday. Maybe after flag burning.

There are many, many issues used for signaling that I feel about similarly.

I see no reason why an invention should be unpatentable simply because it involves software.

That said, it's obvious that the current system is broken; there are many patents which do not seem to do anything new, and simultaneously the cost of applying for patents deters the group for whom they are most important -- small innovators who are unable to commercialize their inventions.

The system needs to be fixed, not thrown out.

Patents on Software make not sense (other protections like Copyright, are essential, though).

Patents are a method to protect significant costs cost of an invention (to incentivize research).
Having an idea for an algorithm is does not represent a great cost and it is not in the interest of society to grant a monopoly).

I have a hard time with this topic. Of course the only thing that ever gets covered in main-stream tech media is the abuse by patent trolls suing Company X because they are using their "electronic key-input device" patent to type on their computers.

We all roll our eyes and go "Damn these patents! DAMN THEM!"

But then I think of the purpose of the patent system in general: to protect and encourage innovation. I think of the research scientists coming up with approaches to genuinely unique and interesting problems and yes, I want them protected from getting rail-roaded by larger software firms.

I've discussed this with a patent attorney before and his feeling is that software patents are generally a good thing, but there has to be ONE change that would do away with most of the bullshit patents: proof of implementation.

Right now, apparently, I can patent the 40-click checkout process and sue Amazon when they implement it... but I never need to implement it, release it or use it in production. I just need to think of the idea and I can patent it.

I imagine a lot of these IP-only firms wouldn't have such a strong grip on stupid garbage patents if it required them to show working implementations.

I believe this is the same way with patents in manufacturing. Someone correct me if I'm wrong, but I think you need to produce the mechanical process you are patenting and at least show it is viable before patenting it?

Whether that is true or not, requiring that of patenters would go a long way of making the work more worthwhile and not just a bunch of lawyers sitting in a room with a few engineers, waving their hands around all day until they invent and patent the use of desk chairs.

I think it's highly unlikely the patent office would ever have the sophistication necessary to distinguish a truly new approach to an algorithm or architecture from a derivative one.

Additionally, there is so much depth and breadth in CS that innovation happens everywhere and is often hidden in the bowels of universities, garages, and offices. Even an apparently novel invention is unlikely to be invented only in one place, or to be invented first by the entity that files for a patent.

I buy the argument that software is math and thus unpatentable. My experience has also been that most software patents (and especially always the most notorious) are trivial applications of an algorithm to some subject area.

But here's a more pragmatic argument.

The current patent system exists to provide financial incentive to bring the number of inventors in an untouched area from 0 to 1.

It is completely broken wherever it brings the number of innovators in an emerging area from 50 to 1.

The first case is probably true in any industry with high startup costs and unproven technology. The second case is true of software and services on the still young, still evolving internet, with low technological barriers to entry and fertile soil as far as the eyes can see.

If we want to see what innovators are really capable of, we'll get rid of software patents and watch them duke it out in the market.

I think, if continued to be allowed, software patents should expire 2-3 years after being issued.

Software and technology moves so quickly that long-term patents stifle innovation and creativity.

Germany had a flourishing chemical industry in the 19th century. You couldn't patent chemical compounds, being things of god and nature, but you could patent the process. This created the perfect environment for competition and innovation. England, by contrast, did allow patents on chemical compounds, and by contrast their chemical industry was weak.

Switzerland continued in the German tradition until recent years, and had a flourishing pharmaceutical industry, despite the lack of patents.

It is interesting that this poll does not mention the problem that I most care about: that the bar for "obviousness" seems to be way too low for software patents. It is so low that I actually worry in my every day work that I will accidentally violate patents simply by solving simple every day problems in obvious ways.

I would support some kind of software patents for truly novel inventions. However so many software patents that I see are almost insultingly obvious, even when you place them in context of their time.

So, yes to software patents if:

1. Shorter time period - 20 years was based on an industrial era time frame for physical manufacture and distribution

2. Much higher threshold for obviousness. Companies should have to declare problems they are applying for patents for publicly and fund a bounty for members of the public or any challenging organization to win by submitting solutions. Only when third parties fail to suggest the methods in the claims should something become patentable.

I'm surprised things like business process patents aren't more widely supported. Especially in the software industry, it's pretty obvious that most applications are the result of somebody developing (or at least, think their developing) a better method for accomplishing an existing task. Correct me if I'm wrong, but don't business process patents enable similar ideas organized differently to equally receive patents? It's truly difficult to lean either way (however, I did vote for the abolishment of all patents). If you're a successful business who is challenged for your innovation, the only protection you really have is a patent. If anything, I feel like those in the software industry should form some sort of agreement and petition the government to enact new rules specifically for this industry. As technology evolves, I shudder at the thought of how the archaic system we have now will all but crumble. There should be a lot more future-proofing taking place.

I've spent the last few years working on a new approach to developing software. I've spent a lot of my own money (at least $40,000 USD) on research to perfect it. Currently, from the research I've done, I've found no prior art.

Should I be able to patent this technology? Should I just release it? If I just release it, wouldn't a large company patent aspects of it and sue me for infringement (it costs $ to prove prior art).

At the very least, wouldn't a patent give me the option to open source the technology without the risk of aforementioned large company coming after me? And if said company does come after me, would it not give me a chance to buddy up with another "large" company?

Imagine a Book of Code, like Knuth's Art of Programming, but easier to search and understand.

If you come up with something new, and write it up clearly enough, it can go into The Book. You get royalties for X number of years (maybe 5? idk). Everyone uses this as a resource. Perhaps there's ARIA-like licensing (where a cafe pays a standard rate to play any music they like), for usages based on how many people use it (so a small software shop pays a small annual fee, and google pays huge fees) - or more likely the owner sets the price. Like an app-store for algorithms. After X years, it becomes free.

The patent system is nothing like this. I'm not sure it's even technically possible, though certainly textbooks get written and some of them are excellent (perhaps with financial motivation, you could employ people like David Flanagan writing up algorithms).

Having such a Book would being programming much closer to an engineering discipline. It would also make contributing to the Book a badge of professional honour, and not disparaged as patents are today. Really, anyone who invents a new and useful approach should be lauded - but the patent system has strayed far from this.

I think the software field is so fast moving that the current time period for a patent is not justifiable. But I do think that someone who invents something should be able to get some advantage out of it, rather than having a Google just waiting to take the invention and make it big.

So I say make the patent expiration period 30 months. This gives you substantial lead time, yet prevents issues like people fearing Apple's multitouch patents years after they've gotten the patent.

Plus it really takes patent trolls off the table, since these patents will have likely expired before they can get them. And it also takes off the table acquiring companies for IP.

No patents would suck a few ways - new ideas might well end up being locked in obfuscated machine code or sealed in ROM until someone puts in the effort of disassembling them and teasing out the algorithm.

But, they still suck less than the alternative, a world in which programmers are prevented from doing the right thing, innovation and start-ups require a willingness to dare a legal minefield blindfolded, big companies have unanswerable bludgeons against little companies, and unproductive trolls get to charge productive people for using ideas they couldn't comprehend, let alone create or use.

petegrif 6 days ago 2 replies      
I think the problem here stems from the fact that people talk as if "software" were one homogenous entity. But as we all know - it isn't. Some software is trivial and some isn't. Some represents a trifling investment and some a huge investment of time and dollars. Some is very easy to copy and some much harder. It is only when we start thinking about such categories that we can make real progress thinking about where and when patents may be appropriate when they are not.

Let's stipulate that the USPTO is not perfect. They do make mistakes. Patents are issued that should not be. But the existence of such patents should not be taken to be an inditement of the entire system. Few systems are perfect, but recognizing this let's further stipulate that advocating tossing the baby out with the bath water on this basis alone is impulsive.

The difficulty is in drawing a line - defining innovations which deserve protection and those which don't.

Let's try a thought experiment. Imagine you have an idea which you believe to be novel. You research the field and it does indeed look novel. You look into the problem. It's non-trivial. It is going to take man-years of work to put together an implementation. But there's a problem. The technology you have to use to implement it is such that it is extremely easy to copy your work. You don't want to have to patent your work. You don't want the time and expense. Perhaps you have principled reasons why you don't want to patent it? But let's consider your options. If you don't get patent protection you are left with (a) trade secret (b) copyright. We already know that a trade secret won't work because your work will be in a form that is easily copied. Does copyright protect you? No. Why not? Because copyright only protects the expression of the work, not the underlying ideas, no matter how novel and valuable they may be. It is easy for a determined competitor to take your work and re-engineer it such that copyright is worthless.

So what are you going to do? That depends on who you are. If you are a huge company and you still don't want to patent it you can go ahead and develop and publish your progress so that it is in the public domain and a competitor can't patent in the area. You are relying on your market strength to carry the day. But what if you are a small company? Are you prepared to risk everything with no protection? It is risky enough anyway starting a company, as we are constantly reminded, but if you can so easily be ripped off, isn't it wise to think twice?

It's your decision. You may have philosophical objections to patents so strong that you just don't proceed. That is your right. But if someone else decides to proceed it seems to me that it is perfectly rational for him/her to seek patent protection. It would be crazy not to. There is plenty of recent precedent of large companies ripping off small innovators even when they have patent protection!

IMHO to evaluate 'software patents' as a class is dangerous. Our industry is too big and the use cases are too various for such generalizations to be helpful. It is only by considering categories of innovation that we can hope to make progress on patent reform is such reform is needed. A knee jerk 'all software patents are the work of satan and should be trashed' doesn't help any more than a strident declaration of IP rights by well financed patent trolls.

I would love to see all software patents abolished.

I feel conflicted about having my name on several software patents - on account of working for (or co-founding) companies that needed defensive IP. Had I not been on the receiving end of a ridiculous software patent lawsuit while I was working at a startup, I would never have filed any patents when I started my own company. If the startup I worked for had not been acquired before they lost said lawsuit, it would have killed the company, destroying some amazing innovation and killing a couple of hundred jobs.

As things stand, even folks who oppose software patents don't really have an option but to file patents of their own unless they want to risk being sued into oblivion with no bargaining chips of their own.

Also if you just wanted to attack trolls directly the active use clause would only kick in after purchase.

We who invent things, we who solve problems in new ways, don't do so because we can get a patent. We solve the problem because when you put a problem in front of us, we can't stop ourselves from solving it. It haunts us. We dream about it. And the only way to make it go away is to solve it. That's the nature of Engineers, the nature of Inventors. Engineers don't think about patents when presented with a problem, they think about solutions. Lawyers think about patents and they don't invent anything.

You might have a better idea than the last guy, but chances are your idea overlaps with his a little. If your new idea has some similarities with an exiting patented idea, implementing it could be risky. If engineers did a patent search for every idea they had, they would find some overlap with existing patents every single time. Nothing would ever get created. The true evil of patents is that they actually stifle, rather than promote, innovation. The effect of patents is opposite their intent.

My suggestion is to cut the period to 12 months and invalidate patents that have been issued so far. I have absolutely no hope there will be a cleanup of the patent house. There are many reasons why regulators fail to match the industry they are regulating in spend and effort. Same goes for finance, medical, software ...

Maybe we just need to change the patent system itself.

I believe people game the patent system by trying to be as general as possible when creating patents.

I believe this stifles progress, I believe stifling progress is wrong, I believe stifling progress hurts us as a country in a time when we can not afford it.

What if a patent's definition changed over it's life time based upon what the company is actually using it for?

I think this would solve a couple problems.

1) It would force the company to actively invest in "idea's" that they own if they are actually makers and not scammers. (Yeah!!, progress continues)

2) It would open up the patent system to redefining the shelf life of patents.

We could call this new system "Shit or get off the pot!" patents.

I'm somewhat surprised that the vast majority of people here are against all software patents. I agree that many software patents are absurd, but I think of things like H.264 and MPEG where true innovation was required on the part of the people who developed it, and it seems clear to me that those people have a right to patent that work.

I'm curious though: what do people see as being the alternative?

The problem isn't whether the patent is in software, it's that that patent office grants patents on trivial things.

Should be patentable: RSA
Should not be patentable: One click

The patent office needs to say "what problem does this claim to solve?" and then "if someone skilled in the art were faced with that problem, would the claimed invention really be novel and non-obvious".

RSA passes this test. Problem: secure encryption without prior secure key exchange. Solution: innovative math that makes that possible.

One click does not. Problem: if customers could avoid logging in multiple times, they'd buy more. Solution: set a cookie, using totally existing technology.

Some are still going to be borderline. Any useful rule is going to have questionable cases.

I think it's just a question of the bar being too low (though being so much so as to make patents that are found acceptable qualitatively unlike patents that I consider acceptable).

For example, I think the LZW patent was deservedly admissible (though it rightfully did not prevent equally-good and patent-unencumbered algorithms from being developed).

All patents abolished. Ideas are worthless once executed and it's ludicrous to own even someone else's idea even before it exists, if it so happens to be covered by your patent.

EDIT: IMHO I think patents can be good, but in some cases (especially software) it is too hard to draw a line between what's patentable and what's not. It is also highly subjective, market dependent, and far reaching in it's implications on preventing innovation if not done right.

The current system, and all of the rather draconian suggestions for change, ignore the issue of independent invention. The only study done on this so far (http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1270160) suggests that almost all infringement is due to independent invention.

Independent invention should negate infringement issues. In fact, in some cases (invention from an even less extensive background) should cause patent re-assignment.

The current system (and all changes proposed so far) also fail to address the US constitutional mandate of causing progress. The current system doesn't.

What is ment by software pattent ? Patenting a method used in software ?

People hear about patent trials but not when startups get their business model copied or stolen by bigger companies. They don't make any noise when they are smashed like moskitos. In one story I've hear of first hand witness from the bad guy side was that they didn't simply trick them into explaining their secret sauce recepie, they also phone the bank and their investors to stop fnancing them. They where big enough to do that. If they had pattented their method for mobile phone geolocalsation in 1999 in absence of gps at the time, things would have probbly run differently.

Patent troll is bad, but when it is for the initial idea of it, that is protecting its inventor during the process of creating the business around it, then I think it's fair.

My position on the matter is that patenting software or other mathematics should require full disclosure of the source for the system. If not expressible in a full-blown language, it's not patentable (e.g., one click).

Let's shorten the length for software patents. For the duration that it is valid, the patent office simply acts as a custodian of the code, ensuring that it works and certifying that it is novel. The patent office should maintain (or contract a company like GitHub to maintain) the repository of pending public domain source.

And once the patent expires, the source is released into the public domain, still under source control.

We can also strengthen prior art rejection of bad patents.

Finally, give enforcement more teeth, but narrow the scope to match more closely what is checked into the repository.

A system like this is more in the spirit of what a patent is: a temporary monopoly with a public-domain disclosure of the idea at the end of term.

Software patents are stupid because you're trying to patent A WAY OF DOING SOMETHING and not A PRODUCT, even if said product is built from ways of doing something.

Example: I patent "A method for storing data on physical storage using blocks" and sue everyone. There are people who try to patent RAM and storage: http://www.google.com/patents?q=a+method+for+storing+data...

As someone who develops software for international markets, though, I'm afraid I'm not immune to this issue, even if software patents are locally unenforceable in my case. I hope developers in other countries (the U.S. in particular) will care enough about this issue to organize and seek reform.

I can't get rid of the feeling that (software) patents are just a means of driving out competition.

For a competitor, it adds layers of unproductive expenditures (legal work), pressures competitors into piling up their own stock of patents as leverage, thus creating patents whose creative accomplishment is the application for an patent. It creates a legal mine-field of patents, more legal insecurities, making an industry unattractive to enter.

(software) patents mean more waste of money, less competition, less innovation and are turning a free-market into a oligarchy-game, where participation is impossible without being part of the big players.

(1) Patents should be analyzed for level of difficulty in coming up with solution. If I had a website like amazon, more than 50% chances that I would have come up with single click idea. But since I didn't had problem, I could not have solution. so such patent should be allow only "acknowledge" status <- that means, a software that is using such patent must "acknowledge" the original creator somewhere , but it can use the patent freely. (2) if patent is used, it is liable for max 5000$ ( for e.g. ) charge. or (3) 500 Million $ charge. It all depend and subjective. current system is go and no go. patents should analyze for level of ingenuity too.

* Any person or institution found patent trolling should find further litigation exponentially expensive.
All these and more measures won't solve the problem... but at least increases the threshold for trolling behaviour...

The patent office should charge some amount with every software patent application to be used for the determination of obviousness or prior art. Then it should post the problems on sites such as this one or StackOverflow as a request for comments. In addition to that, it should post the problem on a rent-a-coder type site. If any of these produced a result reasonably close to what is being claimed the application is rejected.

Simple and cost-effective. This would be far more efficient than having the uninformed at the patent office make decision from position of ignorance.

I believe that we should issue something much simpler than patents: file a very brief description of your invention which is stamped by a trusted agency. It is only evaluated in the case of conflict. That is, if you think I am infringing, you bring it to court, present your originality paper (which dates your idea) and then you have to prove that it is not obvious and that it is useful.

This procedure puts the burden on the claimant, not on some random guy who happens to figure out an idea. It also does not require much work until there is an actual conflict.

There is another problem with software patents that is usually not talked about: they don't present how to build it. Most patents (outside of software patents) present enough information for a competent person to build the device (or whatever) themselves. The idea is that your idea is protected for the duration of the patent, then when it's over everyone else gets it for free. Software patents usually don't do this. I cannot implement, for example, Amazon's "Tabbed browsing" from the description in the patent. I still have to do the hard work myself.

My understanding is that, at least in the UK, patents are a contract between the inventor and the state. The state grants you a monopoly and in exchange you tell the state how it works. The state has the right to seize your invention (after offering you some compensation). My first patent was held up by the UK government for nearly 2 years whilst they worked out if they wanted it !

IMO the fundamental problem with software patents is that the bar for a "patentable invention" is far too low.

Abolishing software patents isn't feasible for me. What about the firmware embedded in many current hardware devices. Where would you draw the line ?

If you abolish patents this really would disadvantage start-ups as large corporations could easily copy any good invention before the start-up has reached critical mass.

Rather than provide substantive input, most of the responses to this query illustrate 1) the shallow nature of most people's understanding of the issues, and 2) a corresponding willingness to highlight such a lack of understanding. Taken from the perspective of a process, one can almost always describe software as a process that effects some change on a physical object, or objects. For example, exposure to novel features (the one's you might think to patent) change the neural functioning of a user which takes it out of the realm of "software" and into that of a physical process.

As I understand it, banks make a large amount of revenues from fees and such. How will BankSimple succeed if it doesn't use that? How will overdrafts work? Will the check just not go through?

I love that they are trying to revolutionize the banking industry, and I wish them well. But I'm afraid that they'll succumb to adverse selection to the greatest degree. The reality is that most of a bank's customers are not profitable (without the fees), which is why they institute these ridiculous fees to either drive them off or make them profitable. If BankSimple can make these previously-unprofitable people profitable again without surprise fees, they'll be a great success.

Let's hope that happens.

1. They're a customer service wrapper for banks, which means banks pay them to provide support. So banks are their customers, right?

2. They actually manage your money for you---a "broker for personal accounts." How do they generate revenue in this case?

Must be a frustrating life. Specially speaking as a software developer, where we're getting a free doubling of the speed every 18 months. I'm sure Moore's Law will run out at some point, but I can never quite appreciate exactly how much that helps us. The helps give a little perspective.

  B      : Activates Kinetic Energy Recovery System
Oil : Activates supplementary oil tank for engine
PL : Turn pit lane speed limiter on/off
Tyre : Adjust electronics to suit different tyres

Any idea why those aren't automatic? I'd think you'd have some computer-detectable indication for when oil would be useful, pit-lanes are identifiable by detecting location, and send the tire type over wirelessly when changed. And why wouldn't you want KERS running?

Seriously, I'm asking. I'm not an F1 buff.

When you have that much on the wheel, I'd think removing what you can would be important. Especially given the very-early line:

>This year designers have had to squeeze in buttons for [KERS] and Drag Reduction Systems along with the usual array of toggles, switches and levers.

Removing 4 buttons would seem to be an improvement, though a bit of a drop in a bucket.

It is interesting to note how F1 technology makes its way into consumer cars.

Take Ferrari, for example. Although first introduced in the F430, the 458 Italia features a steering wheel-mounted manettino dial that allows the driver to configure settings that directly impact the speed of gearbox changes, traction control settings and differential settings.

Starting at about 1:05, this video demonstrates how the various manettino settings are utilized on the 458 Italia, and how they modify the vehicle's driving profile.

Einstein Was Right: NASA Announces Results of Epic Space-Time Experiment nasa.gov

It's not all that epic. These effects had already been measured by other experiments and were found to agree with general relativity to much more accuracy than the GP-B measurements. What GP-B brought to the table was a direct measurement, as opposed to indirect measurements used by the other experiments.

However, because the way they measured it pushed the limits of engineering, if GP-B had NOT agreed with GR there is good chance the results would have been dismissed as most likely due to equipment flaws.

While it is in general a good idea to confirm measurements, especially using different techniques, in a case like this where the confirmation will be much less precise than the other experiments and will likely be rejected if it fails to confirm, you have to wonder why this was funded over other projects.

The answer to that turns out to be simple: politics. When space scientists ranked all the proposed missions under consideration, GP-B came in dead last. However, its proponents went to Congress, and got Congress to override the normal process for prioritizing missions, forcing NASA to move it to the front, ahead of more scientifically worthy missions.

There are a lot of very worthwhile scientific missions that we can't fly due to budget limitations. It's a shame to see $750 million of the limited budget go to a mission so far down on the importance list.

It would be interesting to find out if using Hans Montanus's non-canonical formulation of GR (which involves a Euclidean metric and perfectly flat space-time) would yield the same numerical predictions, just with different "book keeping".

That would put a different spin on the notion of Einstein "being right" as I think a lot of folks subconsciously equate GR with the "strangeness" of the Minkowski metric and non-Euclidean space-time manifold.

Why Google's hiring process is broken teambox.com

ChuckMcM 5 days ago 4 replies      
Lots of interesting stories.

Disclaimer, I worked at Google for 4 years ('06 - '10) and interviewed a lot of folks (it was always a part of the job) and did a number of phone interviews too.

The process then (as perhaps now) was broken and some folks within Google understood that. The process and goals were pretty simple, hire smart people that get things done.

The process was aimed at finding smart people who get things done. That, like the phrase "largest integer" is easy to say and rolls off the lips but when you need to actually write out what it means gets a bit squirrely.

The first challenge is what does "get things done" mean? Well for college students it means you got your diploma and at the same time you contributed to some FOSS project. For people with 0 - 5 years experience it means you shipped a product where you did most of the coding. For people with 5 - 15 years experience it means you shipped a product where you did most of the coding. For people with 15 to 25 years experience it means you shipped a product where you did most of the coding.

Did you see what I did there? Google wanted smart people but the definition of smart was "you write a lot of code" and "get things done" was "that code shipped in the product/project." Fundamentally they didn't have any way to judge or evaluate the 'goodness' of what someone did if it wasn't writing code. Designers don't write a lot of code and they don't generally have a good metric for what constitutes good which can be empirically tested. The process has a hard time accomodating that. And if you're "good" at spotting problems in a process or getting folks organized around some better way of doing things? That's not measurable either.

There was a company, BASF, a chemical company which had an advertising campaign around the fact that they were part of the process and materials that made quality products, their tag line was "We don't make the products you buy, we make them better." [1] And I noted that Google was exceptionally bad at hiring "BASF" people, which is to say people who bring the quality of other work up, or products up, or processes up.

The people who did those roles in Google all started out as coders and that is how they got hired. It was only after they were working there that they (and Google) discovered they had this leveraging effect.

In order to keep bias out of the process, Google isolates the steps where bias can creep in; separated the folks who decided hire / no-hire from the folks who decided on compensation; the folks who decide to hire and the folks who decide which project they work for. For all my time there, you could not interview for a specific job, you interviewed to get 'in' and then your name showed up on a list and the allocation process would determine which project got you.

Often a candidate would ask during the interview "What would I be working on?" the only truthful answer was "That is impossible to say."

Before you even get to that point though you get into "the system." Since Google keeps a record of everyone they have interviewed or has shown up as a lead and not interviewed. There is a long, long list of people (I once joked that it was everyone in the market). If you are an employee and you might know that person, common employer, common university, etc. The system could automatically send you an email asking for your opinion on the candidate.

This isn't really any different than any other company, person X shows up in the candidate list, people who work at the company who worked at person X's company are asked if they knew this person when they were there. But it can have unintended consequences.

Lets say there is a person X, who gets hired, from company Y, and person X really didn't fit in at Y and felt really abused by the company. Now new candidates from Y generate an email to X with the standard "You worked at Y when candidate Z did etc etc." Now person X is still pissed off about how Y treated them and so they respond to all of those emails with "Yeah, candidate Z was a crappy engineer, everyone had to carry for them they never did anything useful." Maybe someone else from Y says "candidate Z was great, everyone turned to them for advice." The process of separating the interviewers from the decisions means that this feedback bubbles up all equally weighted. Hard to know that employee X has said the same thing about every candidate that has come from Y, and if the committee sees two comments one positive and one negative and there isn't anyone on the committee who knows any different then how do you evaluate?

The simplest solution if either has an equal probability of being the 'correct' assesment is that you pass on them because you can't know if you have bad data. And that was a part of the process that was fundamentally broken.

Because Google gets a metric crap load of resumes and candidates all the time, passing on someone who is +1/-1 like that makes sense because you can't know which of the two feedback comments more accurately reflects the real candidate behavior. The result is that hiring someone with a grudge can poision the feedback pool for a bunch of possible hires. If you weren't Google and didn't have this huge backlog of candidates, you might dig deeper to find out which one was the more accurate representation, but if you are Google you just move on. Externally that sometimes appears that you just stop answering the phone.

It also means that you miss out on quality people who would be good for the company and ultimately Google will have to find a way to address that issue (if they haven't already) because they are running out of people to interview.

As with most things Google, you combine a data-driven, automata friendly process with fuzzy data and alternate agenda actors, at the scale Google runs at, and you get lots of weird artifacts.

My 2 cents: I was contacted by a recruiter, unsolicited through a referral, and asked if I was interested in interviewing. At the time, I already had an offer from one of the other big companies, which I was upfront about. The recruiter said it was ok, and would set me up for the first round of interviews. After about a week of emails, I just simply stopped hearing from the recruiter. Not a single interview, no reason for terminating contact, just plain dead silence. I tried emailing her a few times and left her a voicemail, noting very politely that they had contacted me and not vice versa, and asking if they were still interested in setting up an interview, but all I got was stony silence. If that's not broken, I don't know what is. For a company that hires the best engineering talent, they either hire substandard HR people, or perhaps most HR people just operate at a different level of efficacy.

Google is considered (or at least was, by other tech companies) to have a very poor sourcing and general recruiting experience. It was assumed to be because they contract out the work.

As a contrast to that, at MSFT, we had full-time recruiting staff generally split into college and experienced recruiting (there are some extra bits not important to this). The experienced recruiting staff was assigned to divisions and worked for usually a couple of years at a time sourcing candidates specially suited to their area. The college recruiters carefully handle and ensure that only one person is in charge of each candidate, they're marshalled through all the steps, know when they'll hear what piece of info back, and are absolutely brutal with us hiring managers about making timely decisions (not that we ever drag our feet <grin>).

While working at MSFT, I was contacted several times by different Google recruiters. Each time, I was left sort of half-indifferent e-mails or voicemails, which I was informed was the desired style of contact. I'd fire them off to my sourcing manager to forward around the recruiting org for a good laugh and jokes about where these people had been before (it's a small industry, and they often would point out ex-Cisco recruiting washouts, etc.).

That said, you can certainly go far on name alone for your recruiting, especially when your options are expected to pay out well. But it's unfortunate to have to try to build teams despite your recruiting efforts. I'd hate to have been a hiring manager there.

I had a similar experience. Same letter from the recruiter, back-and-forth with rate-your-skills, but then nothing. It's strange because the position they had in mind seemed directly aligned with my proven interests and abilities. Hell, my cover letter was pretty much describing the job they wanted before they even told me about it.

I really see it as strange that I never got a call back. (Maybe it's not over yet, it's only been a few weeks.)

I disagree with article's conclusion that they are selecting for "backend" engineers. They are selecting for people that think over-engineering every little data structure is the way to build good programs. The skill software companies need is the ability to get a hundred subsystems tested and working together, which is totally different.

I know someone who recently interviewed with Google and he told me about the algorithms question he "got wrong." After he came up with a simple solution to a simple problem, the interviewer told him the better, googley-er algorithm, which was: a) far more complex and difficult to implement, b) had far more corner cases that would need unit tests, c) had more overhead in the expected case, but d) technically had a better big-O in the (extreme) worst case.

In other words, the interview was screening for people who have been to school but haven't ever built anything.

Google's process is broken because it generally presumes job candidates know what specific job they want, and they don't. To put it in contrast, I also applied to Microsoft and they immediately assigned me a specific recruiter that I could email directly. Google needs to give job candidates a person to contact rather than expecting talent to go online and do that weird "job shopping cart" thing they have on their website.

The other reason the hiring process is broken is because it's totally backwards. The hiring process doesn't indicate any appreciation of talent. Talent in this industry consists of wanna-be rockstars. Talent wants the company to say "Hey, you're great. We want you. What's it going to take to get you here?" Google's approach, like many other companies, is "Go online, email us a resume, and we'll get back to you whenever we feel like it." Most people with talent are going to say "Forget that. You got it backwards. You need me more than I need you."

To put it in perspective, think of how professional sports teams recruit college athletes. The professional teams do every damn thing they can to get college athletes to agree to join the team. They send out recruiters that pay for meals, make the candidates feel special, and everything else to make the talent feel appreciated. That's how you recruit talent. Taking the approach of "Go online, do our rinky-dink job shopping cart thing, email us a resume, and we'll get back to you when we feel like it" doesn't attract talent and never will.

I haven't had an interview in over 6 years, but I have been approached by multiple recruiters in the same time span.

I actually dread the day I choose to switch jobs and have to face another technical interview - considering that my knowledge of college-level CS has declined over time. It's not because I am less skilled now than I was before, it's because you don't have to constantly create fantastically fast algorithms on a daily basis (at least in my job!).

The skills that I have developed over the past 6 years - designing complex components that interact with other complex components in a hugely complex product, making improvements in the design of a 20 year old codebase, deciding between fixing a bug and compatibility etc., intuition about design choices and how they fit in the product, and yes, debugging (!) - none of these are covered in technical interviews these days.

Sure, I could explain how a b-tree works - but that's not going to help me resolve my next bug.

My own personal "horror" story.

Google reached out to me, unsolicited, for a web developer position. I wasn't looking, but I thought cool, I'll at least talk to them. The recruiter kept asking me about how good my Java was. I repeated what it said on my resume, that I only used it in college, but that my OO skills were strong and transferable. Afterwards the recruiter emailed me, and said I wasn't a good fit because I didn't have enough Java experience. I didn't even get a technical phone screen.

Java experience is serious business.

Google manages not to hire someone who didn't want to work there in the first place. Sounds like the process is working just fine to me.

In all seriousness, there may be some issues with their hiring process, but I think the Google hiring practices would best be analyzed by using the aggregated data, rather than the trickle of anecdotes we tend to hear about in public. Even if Google got their hiring right 99.9 percent of the time, there would be hundreds of people, if not thousands, who were perfect for the job, and still didn't get hired.

It doesn't take a designer or user experience expert to note that google products lack consistency and don't interopt with each other very well. I think this stems from larger issues that are much harder to fix, or through 20% projects and acquisitions that were developed independently of a common set of standards. I doubt they are ignoring it.

Perhaps the lack of a "Google standard" enables eager developers to create amazing new products, like Gmail.

What position was the author interviewing for? Google (and most big companies) seem to pigeonhole candidates into a certain slot, even when it is obvious they'd be better off in a different title.

The real way in which their process seems broken is the wildly different experiences people have seemingly at random, depending on who their arbitrarily assigned recruiter is. When I interviewed I had none of this weird "rate yourself" questions, and a mostly positive experience. But it seems like if I had randomly been assigned a different recruiter, or someone tried to fit me into a different bucket, I would have had a wildly different experience. How can you compare candidates evenly when their experiences seem so randomly different?

I haven't interviewed at Google, but I've interviewed at a few other companies that seem to follow a similar style.

I'd agree that the hiring process may be broken, but that these companies don't completely realize it. I have no problem with the intensely rigorous emphasis on CS (and math, sometimes), but I've been on these interviews and realized that (after seven hours of interviewing) we still haven't discussed what the company actually does.

Here's the thing - when you're interviewing a very experienced candidate, the candidate may know more than you do about how to write the software. They may know things you haven't even thought to ask about. This isn't a reason to skip the technical grilling, that's a critical background. My problem is that these companies heap it on and on and on, and then they make an offer based on compensation for someone who can survive a technical grilling.

What if this candidate has experience writing software in your domain? What if the candidate has a deep understanding of the business space and knows a lot about what those customers are looking for? What it there's a completely different approach that you haven't even considered?

A candidate like that is, quite frankly, probably worth much more than someone with a strong theory background but no real domain knowledge (though I would still hire that guy). So I suspect that these interviews are good at establishing a high bar, but aren't so good at identifying certain types of developers who could be absolute game changers for the company.

Ironically, the only time a company did do this for me, I didn't get the offer ;) It was at netflix, and (after the obligatory data structures grilling), they talked to me about all their data mining needs. I told them I didn't have much of a data mining background, but discussed how they might approach these problems a completely different way.

A few days later: thanks but no thanks, they wanted a data miner. Oh well ;) Still, it was one of the best interviews I've been on, actually fun and energetic. And I felt that if they'd made me an offer, they'd know why.

This is what may be missing from a lot of these interview processes, which is why they may be "broken" in the sense that they don't really get at why you'd want to hire a specific person, beyond the fact that he cleared a high technical bar.

My Google offer experience: I turned down a offer from Google last spring. Long story, but my reasons can be summed up as having a more challenging opportunity in a leadership position at a small company versus having to enter the "engineer" lotto where you don't know what team and project you get placed on.

Funny thing is, I had a call from one of their recruiters today. A couple times previously somebody contacted me by email and I said "sure, call me", and didn't hear from them. But this guy was out of the blue and from a different office and had a different approach to it.

The message was that things are different at Google and they at least from his office's perspective, they treat each recruitment uniquely.

My take away is that Google is a big company and you'll get different experiences depending on how you enter the HR process (college grad applicant, versus sought after name). The OP in this case is doing a lot of generalization.

I've interviewed for a summer internship at Google twice: this summer and last. The first time I interviewed with them, they emailed me the same day to tell me that my interview went really well and they'd like to proceed to host matching. Unsure of the way the process worked, I emailed the recruiter a week later to ask what the next steps were. She called me back half an hour later to ask if I had any deadlines, which I didn't. The reason for the delay, she said, was that Google tried to first match returning interns with hosts before new interns. A couple weeks later, I had a phone interview with a host, it went well, and I was assigned to work with him over the summer. That was that.

This summer, I decided I wanted to return to work at Google again, but I had a specific project in mind I wanted to work on. I filled out a form stating my project interests (which were very specific this time around), but no recruiter reached out to me. I talked to one of my colleagues at Google from the previous summer, he talked to HR or something, and I got a new recruiter. Then I went through five host interviews in three days, picked my favorite, and that was that.

So in my experience, the hiring process at Google isn't that bad. It's just that if you have a delay that's too long, you need to follow up.

This seems mostly like a standard recipe for baiting traffic from HN to a blog: make up a sweeping generalization about a company people are deeply interested in (e.g. Google, Apple, Microsoft, Facebook, Twitter) based on a very limited data set, put that in your headline, then have your article talk about how much better your company is at XYZ by comparison. It's the HN version of the humblebrag tweet.

I think an underlying reason for so many anecdotes of the sort in the comment threads here is the sheer number of hires the Goog is trying to make right now -- according to http://investor.google.com/financial/tables.html, they've grown headcount by close to 10% in Q1 alone so far.

Life for their recruitment folks is probably fairly interesting these days.

I recently talked to a colleague who was hired as a developer by Google.

He went through 3 rounds of "hiring committees".

3 different committees to make a developer hire is obviously broken. The ability to evaluate culture and skill fit should be possible with a hiring manager and a few prospective peers.

It sounds like you were going through the software engineer interview process, when what you wanted to do is product management. This is a recruiter-fail: when someone expresses an interest in product decisions, it makes sense to send them through the PM interview process. But it's not really representative of what it's like to interview for all the different job families that one might apply to.

It does seem like Google is more focused on the programing side of things and design is an afterthought for them. Which is a pity because I feel overall look and design dramatically changes my perceptions of how good something is.

Another beef I have with Google is the sorta half-assedness of some of their products. They seem to release things early to get them out there, which isn't necessary a bad thing but now I've started to realize this it's soured me to using some of their api's and products

My experience so far has been very different. I was contacted by a recruiter a few weeks ago. I had a phone interview within a week of the initial contact. Within three days, they got back to me to schedule an onsite interview.

The one negative I've encountered so far: Google has an office near where I live, but will not interview me there. This will require significant travel on my part.

I had a relatively good interview experience with Google. I wasn't hired but I felt that the process was fair. True, it was long and I had to invest some significant time to freshen up my algorithm skills. But overall I was left with a good impression.

I do think that Google puts too much accent on algorithms and college-level CS. I consider myself a good programmer. I created two moderately successful Micro ISVs in my free time. I contributed a huge chunk to the product at my corporate job. I get things done. However I felt that this is not what Google looks for even if the say they do.

"User are not As and Bs."

Reminds me of working at MS as a designer. It's challenging for an engineering-focused company to suddenly try to integrate design into their products--especially one so focused on metrics. This often leads to "duct-tape design" instead of a clear unified design. User testing no longer validates design, but completely drives it. E.g., because our study found that users clicked more buttons when they are bright red and blinking in their faces, let's make all buttons blink red! Brilliant? No.

Google probably expects that all designers/product management folks that they are interviewing to be good at programming too. There are good programmers, good designers and some people who are really good at both. Since a lot of people want to work at Google, they are using that to their advantage and hiring good designers who are also good programmers.

I'm not sure what the OP suggests is feasible in most situations. It's disruptive to the existing team and you have to have "throwaway" projects around for the person to do that won't cause problems if they're late or poorly implemented (and if that's the case, why do them?) Also, you're letting every guy who "interviews" learn about the internals of your systems, code base, security, etc to some degree, which is not something most companies want to do.

Interviewing is hard, but it's clearly not totally broken, given that some companies obviously do a far better job of it than others. Do we really believe that the big consulting companies or banks don't know how to filter for the better candidates given how much their business depends purely on having the smartest people? Are Apple, Amazon and Google really just more lucky at hiring?

One non-interview thing that I DO like to look at is publicly viewable work like open source contributions, blogging, social media activity, etc. If someone wants to work on web sites, and they're not doing anything web-related outside of their job, I have to wonder how passionate they really are about the domain.

Hiring is hard because understanding people is hard.

There's also the problem of selection bias. Your technical interviewers are going to look for people that resemble themselves. In a broad sense this is because they think they're smart and everyone else is dumb (and rightly so). The problem is that this strategy can be far too successful and you will invariably turn away a perfectly suitable selection of candidates along with the unsuitable ones. It's human nature and difficult to detect.

There is another form of selection bias in the interview process. You need to know that the candidate you're going to hire is going to be competent, assertive, and talented. However the exact match of skills, abilities, and personality traits that fulfill those broad categories are going to be based off of those skills, abilities, and traits you believe have helped you to be successful so far. When interviewing someone it is far too easy to check off the features a candidate is lacking and miss the ones they do have that you do not. A good hire, IMO, is someone who has some of the skills and abilities you already have and some you do not. Yet all too often, we look for people who have ALL of the skills we already have instead.

I think strategies such as the one in the article would at least by-pass many of the definicies noted above. However I think it might be impractical in some scenarios (ie: when the candidate is already in a position at another company, or when they have received attractive offers from other companies). It's a start though and I think alternative strategies should be considered more often.

Perhaps Jason's approach may come out of his intuition, I'd like to explain it from a more "academic" perspective. In economics, the labor market is often suffered from information asymmetries where the employer has little means to determine the productivity of prospective employees. Therefore, if the employer is willing to pay average wage, it will obtain below average workers, as workers who has higher than average productivities won't accept the offer. Such a phenomenon is also called "the Market of lemons" in the context of used car market.

The root cause of such a market failure is because workers' productivity is difficult to measure. A certain measure has to be introduced to indicate the worker productivity indirectly (often termed Signaling in economics). For decades HR/Recruiters have been addressing this problem by using different metrics as the signals/indicators. Popular signals include education (GPA, university prestige).

Programming may be a bit more challenging as multiple factors can affect programmers' productivity, e.g., intrinsic intelligence, problem solving skills, the speed of learning. Our hard-working recruiters/interviewers have introduced some new signals --- brain teasers, coding tests, etc.

What Jason proposed in this blog post is that we don't need all those signals, they are all inaccurate and can be fooled around by a well-prepared interviewee, why not directly measure their performance by working with them for a short period, say, three weeks.

That does sound like a good idea. IMHO, that's basically what internship does for students, but not sure if that will work for full-time employees, as it will incur extra opportunity cost for them.

I like this approach of really testing out the waters before committing.

I find there is also a divide between HR/recruiting and the lead developers. Once I had two interviews at a company. The first one from HR and a second one from the lead developers.

The attitude of the developers made me think they didn't have much say into the whole process. They did ask the best (read hardest) questions. This interview order seems fine, though questions like:

how many lines of codes did you write in language X?
If we ask you to build Y, could you, and how would you go about it?
If there is a problem in the weekend, and we call you, would you come over to fix it?

Could perfectly be asked in the first round of the interviews. And if you really want to be sure that a person will come to the office, if need be, then maybe plan the contract meeting at midnight on a saturday :)

One thing I noticed while last searching for jobs is the apparent inconsistencies in job listings.

Pre-requisites like: PHP and Ruby, Web standards and Flash, thorough understanding of javascript (jQuery plug-ins), Photoshop or Illustrator and version control, familiar with Linux and .net.

At first I ascribed these pre's to unskilled job listers, but maybe this is the start of the negotiation process?
- "I do know X, but have to work on Y"
- "That is fine, have you thought about salary yet?"

Is this really a thing in recruiting, or am I seeing things?

I'm sorry. If I was currently gainfully employed and looking for a job, I don't think I'd be on board with your system. I appreciate the idea of getting to know a company, but, I'd be applying for several companies every day. Even given the current interviewing speed (several hours), it'd eat up time.

Doing part-time contracting is just not going to cut it. I've done moonlighting before: no one was very happy with my work, including me. You can't hire me this way if I have a job already.

If I was unemployed and looking, I'd be more interested, but you would not get a cut-rate from me: you'd get a full consulting rate & contract.

In my opinion, if you want the best engineers, you need to know them and offer massive bait. Because they aren't just going to jump for anybody or any old normal reason. You have to offer them what they want - and more than their current job does.

Tl;dr try someone out part time before hiring them full time.

Ignoring the link bait title of the post, I think the OP's suggestion is good. However, it's usually not possible. People are working full time and don't have extra time to work on your side project.

Interviews should include the same activities the interviewee will be doing during their job. Programmers need to program. Designers need to design. Sales people need to sell. It's actually quite easy to do this effectively in an interview and plenty of companies do that quite well (i.e. They don't suck)

Finding great talent is hard but identifying talent is not difficult. Yet, finding and identifying talent is just half of the story. The other half is determining if the person can focus in what you need, be motivated, take the initiative, and deliver great work. That's the difficult part. More often than not, very talented individuals have a lot of stuff in their heads, such that mundane but essential work ranks low in their platonic priority list, and that affects their capacity to concentrate and deliver.

My experience has been the opposite. Best employees aren't desperate to work for you. They're gainfully employed, and you have to poach them. No one I know who is productive would give up this much time to something. Almost everyone I know who is unemployed and desperate would.

The key to finding good employees is to do what Google does. Find successful people. Don't have them come to you -- go to them. How do you do this? Talk to professors and see who top students are. Read publications and books in your field. Hire whoever wrote them. Find neat free software projects, and hire the authors. The list goes on. People like that generally won't want to work for you, and the trick is to recruit them somehow.

If I wasn't willing to work contracts, wouldn't requiring me to contract up front take me out of the running?

Or does this whole thing assume people will just go without health care for a while? I could understand that if there weren't other choices, but given that other full time employment is readily available, who does this?

I think a brief conversation about software development and a longer conversation to determine how smart the guy is is what matters. Even someone who barely knows how to code can learn on the fly if he's smart/competent enough.

Unless of course the blogger is also saying that he never posts a job and only works through reference, which defeats the entire argument anyway.

One issue that has been ignored is that of security / confidentiality. What happens if the individual you are "courting" works for one of your competitors? Any project that he would work on for you would likely require access to sensitive, proprietary data. Sure, you could force him to sign an NDA, but that puts him in a strange situation post-project.

How do you balance giving the candidate access to your data such that he can work on a meaningful project (read: the results of which are actionable) vs. having him toil away with some dummy data just to see how he thinks?

I strongly agree that the try before you buy approach is incredibly important for determining difficult to predict cultural and team fit. That being said while it is essential for early-stage companies to get this right, as pointed out in the comments, it can be difficult to scale and can be inefficient to make-up projects for potential hires, give them access to code, etc.

Some companies have found ways to bake cultural fit into their standard application process to great success. Twilio for example asks all applicants, business or engineering, to build telephony apps using the Twilio API before applying. This self-selects for people who are more willing to do research, be creative, and in general improves the likelihood that they will get along well with the team.

I am a bit biased here, but another path I would definitely advocate for is using interns. This is similar to the contractor approach but with a number of benefits in terms of price, and the fact that a hiring decision is not implicit at the end of the term. We have seen many startups build a pipeline of early hires by taking on multiple interns and seeing who is the best fit over the course of a few months.

@JasonFreedman That's great if it works for you, but personally I feel that you're just putting all the risk with the employee, which is shitty.

If someone is out of a job, the last thing they want is a 3-week gig. Yeah, I get that "well if they're good, they'll probably be allowed to stay". I wouldn't even consider working for a contract-to-hire position with a "few weeks" of guaranteed work. As a business, the risk is on YOU to hire the right person. As an employee, you're offering me what, maybe a month of rent while preventing me from going on most other job interviews? That's not a risk I'm willing to take. I'd rather do 3 interviews every day and have 5 jobs to pick from at the end of a week.

Also, the projects...I'd guess that the projects you have people work on aren't very beneficial to your company, or are so focused that they might not take advantage of the talents of the employee.

On the flip side, I think working with someone is the best way to get to know how they are / can be as an employee, and sometimes I feel that otherwise good employees will stumble on inverviews, so giving them some time to really prove themselves can be a good option....but I think that by limiting yourself to people willing to risk a few weeks on a long interview are going to be the most desperate of the desperate.

IMO, an interview is to working at a company what speed-dating is to a long-term relationship.

The success of a team is not just about the competence of each individual but how well the individuals work together as a team, and individual competence is not totally correlated to working well with a given team.

Intuitive explication of Fourier Transformation altdevblogaday.org

mturmon 5 days ago 2 replies      
The quickest "explanation" of the FT I ever heard was in a casual aside from a professor once -- he referred to the Fourier domain as the "reciprocal domain". It took me a while to work out what he meant.

It was just that frequency = 1 / time. In this (barbarically reductive) conception, taking the FT is just a change of variable.

This relationship is one way to "derive" many of the standard Fourier facts.

For example, the scaling property, that if x(t) has transform X(f), then x(at) has transform (1/a) * X(f/a). It also "explains" why time signals concentrated around t=0 tend to have lots of high-frequency content (f = 1/t = 1/0 = infinity), and vice versa.

It also "explains" why the inverse FT formula looks just like the forward FT formula (since if f = 1/t, then t = 1/f). And, for the same reason, most of the duality relationships between the two domains.

All with just arithmetic! You can dispense with linear algebra, not to mention complex arithmetic, groups, or measure theory.

The author wrote "This formula, as anyone can see, makes no sense at all. I decided that Fourier must have been speaking to aliens, because if you gave me all the time and paper in the world, I would not have been able to come up with that." That sounds like a predictable symptom of trying to understand Fourier analysis while avoiding linear algebra. And that seems like unnecessary masochism, because basic linear algebra is very useful and pretty easy. And once you have it, (elementary) Fourier analysis becomes trivial to understand as a change of basis by recognizing the supposed "no sense at all" formula as a perfectly sensible change of basis to a basis of sinusoidal functions.

Then you just need to understand that the sines and cosines are a complete basis. So think about the sines and cosines for a while until you can say "yeah, they're orthogonal, and I can believe they're a complete basis for the kind of functions under consideration." Then to promote this from "I can believe" to "obviously," for the discrete FT (the orthogonality and) counting/dimensionality arguments suffice, and for the continuous FT you can look at Gaussians, say "obviously Gaussians are a complete basis for the kinds of functions under consideration" and then do the easy integrals to show that any Gaussian can be expressed as a linear combination of sines and cosines.

(This assumes you're interested in transforming reasonably smooth things like wavefunctions in chemistry, as opposed to trying to see how far you can push Fourier analysis into the netherworld of bizarre jagged twisted functions shown to exist by invoking the Axiom of Choice. If you want to do that, feel free to take a course from Terence Tao studying theorems whose prerequisites involve concepts like "countable.")

tspiteri 5 days ago 1 reply      
The article, and quite a few posts here, describe the way they understand the Fourier Transform as the way to understand the Fourier Transform. For it to be intuitive depends on who is trying to understand it. Getting that out of the way, this is how I find the Fourier Transform intuitive (using pseudo-code instead of math notation to make it a bit verbose and emphasize the steps):

    fourier_trasform(signal sig(t), frequency freq):
let sinu(t) = sinusoid with frequency freq
let mult(t) = sig(t) * sinu(t)
value = integral of mult(t) from -infinity to infinity

If the input signal sig(t) has the same frequency as the sinusoid sinu(t), then integrating mult(t) over infinity will give an infinitely large value, and that case is handled better by the Fourier Series.

If the input signal sig(t) has no relation to the frequency of the sinusoid, then integrating mult(t) over infinity will give zero.

If the signal has a component with the required frequency, it will kind of resonate with the sinusoid and give a non-zero value. The value then depends on the magnitude of the signal and to how much it "resonates" with the sinusoid.

When you do this for a range of different frequencies freq, but using the same signal sig(t), you can plot how much the signal sig(t) resonates with all frequencies, and that plot is the plot of the Fourier Transform.

I think these concepts became clear to me when I learned about the complex plane, Euler's formula, and demodulation of an FM signal.

Particularly enlightening was the demodulation of a frequency modulated sine wave when the tuner was imperfectly matched to the carrier frequency. Looking at it on an oscilloscope was similar to watching an old TV with the Vertical Hold improperly set.

That made me start thinking in terms of a signal (sine wave) that was a cycle rather than a sinusoidal shape. Seeing that you can graph the amplitude and phase of any signal on the complex plane and that the frequency was the change in phase from one moment to the next was the aha! moment.

Then if you think about sampling and how if you sample a sinusoid exactly at its peaks how that would graph as a constant point on the complex plane, but if you sampled at any other mismatched frequently, the point would rotate and change amplitude with respect to either axis. The further away from the actual frequency you'd go the the points would look more random, and they'd average out to zero with fewer samples.

This would be a fun animation or java applet to make; I'm sure someone has done it.

To really understand the discrete fourier transform properly you need to understand the mathematical concept of a group. Fortunately, you only need to understand one particular group G, namely the integers mod n. Once one thinks of the input to the Discrete Fourier Transform (DFT) as a function on G (i.e. the input to the function is an element of G and the output is a complex number), then it is possible to frame the DFT in terms of a map between functions on G to functions on the dual of G (using something called Pontryagin duality). The thing is, functions on the dual of G multiply pointwise whereas functions on G itself multiply like polynomials mod x^n - 1.

Therefore to multiply polynomials, one thinks of them as functions on G, uses the DFT to take you to functions on the dual of G, multiplies pointwise, then does an inverse transform to get you back to functions on G again. I'm skimming over lots of details and oversimplifying a bit, but what I just described is the process of using a convolution to multiply polynomials.

The really great thing is if n is a power of 2. Then you have this cool Cooley-Tukey algorithm called the Fast Fourier Transform to do the DFT (and IFFT) really fast (in time O(n log n) instead of O(n^2)). It works by recognising that computing an FFT is precisely the same thing as evaluating a polynomial at the n-th roots of unity. This can be done by repeatedly breaking the problem into halves and recognising that the same pattern of roots of unity occurs in the first half as in the second. By factoring that out, you can (recursively) save yourself half the work.

Again, oversimplified, but that's the nub of it.

I like the explanation, but there's no reason to skip over the complex exponents and Euler's formula like that. They're not really that hard to understand intuitively: think of all multiplication as a continuous process. Then f = e^x is simply the function that transforms the multiplicative identity (1) into ln(x).

Substitute "-1" into the left side of that equation, and see that no real value of x will suffice. This is related to the fact that the imaginary constant (i) wasn't discovered, it was simply declared as an unknown quantity that squares to -1.

The real magical part is that i still works in more complicated situations: multiplying any real number by e^(ix) as x increases gradually transforms it into an imaginary number, and then into its own negative, behaving like a counter-clockwise rotation when visualized in the complex plane.

Do not let your domain expire with Google Apps benreyes.posterous.com

A few weeks ago I tried to register Google Apps on a domain I purchased, and found that it'd already been registered by someone else. I sent an email to the support team explaining that there was a previous account and that I was the new owner, and upon proving that the domain was now mine they deleted the old account and had me start anew.

Obviously, while the email-support method is safe, the automated system for unlocking admin access based on "proof of ownership" is pretty scary! Seems like this could be solved by requiring you to prove ownership and then releasing new auth info to a linked email account on a different domain. That helps to establish both present ownership and a chain of ownership back to the last time you had authorized access and were able to adjust the "emergency email account" setting. It's not perfect, but it's a heck of a lot better.

It also seems to me like someone wanting to abuse this right now could do so pretty easily: you can confirm that a domain is available and that it has had a google Apps account set up in the past before you spend a dime, so you can just set a computer to trawling known Google Apps domain names (e.g., by looking at traffic on large mailing lists) to find ones whose registration has expired.

Hopefully Google has added some mitigating steps to keep this sort of thing from happening.

Google's problem isn't in their authentication, it's in the whole idea that having a domain name now means I should have access to the previous google apps account. They're separate entities.

This is probably related to why google isn't able to move an apps account to a new domain (our real domain is just an alias to our google apps account on previous company name's domain).

Any idea if this applies for a domain that's an alias to your primary domain?

For example, if you have foo.com as your Google Apps domain, and you have foo.us as an extra domain that was aliased but then expired, does that expose the foo.com Google Apps account?

I want to point out that as a ICANN registrar not a day goes by where some tech person working on behalf of a customer will contact us and request an auth code to transfer out a domain name. Just like that. As if we will send one to anyone that asks. Later when the customer makes the request many times the domain ends up at another registrar in the name of the tech person, isp, web designer etc. who has been told they need to be able to login and make changes. The name subsequently is deleted for non-payment (customer isn't notified and invoice goes to new contact) and they loose control of their domain.

Wait. Please tell me I'm misunderstanding. You needed only to enter a user's e-mail address and birth date to change his/her password? So, even without the previous (actual) hack, you could use this page to change the password of a family member, friend, co-worker, and nearly anyone else you've ever exchanged e-mails with if you know their birthday (or they publish it on Facebook)?

How does someone even conceive of something like that without realizing the glaring problem with it? How does it pass muster at a major corporation that has hired security consultants? This is utterly flabbergasting.

For having three different security firms working with Sony on the hack a month ago, are they really just pushing out the new PSN without a proper, full security review? I mean, any competent developer would immediately realize that this password reset system is flawed by design, especially with the fact that the user's information requested is the information the hackers already have!

This does not bode well for the near future of PSN as a whole. If something as simple as a password reset feature is still being built without security in mind, then how does the rest of the updated system fare?

In their defense though: What data could ask Sony for? All the data that Sony knew about these accounts has leaked, so what ever they ask for, the hackers with the leaked data know it too.

Exception is maybe the credit card number, but that would mean that only a small subset of the original account holders can change their password.

Or you use a PS3 device ID and only allow changing the password on the device, but that is also known by the attackers and I'm sure it could be spoofed.

Not even sending a token to the email address on file would work in all cases because the users might have lost their email accounts to the breach too (by reusing the same weak password).

The answer is to rebuild/rebrand the networking for the playstation with a strong partner like Amazon, Google, or Valve/Steam.

A partner like Amazon for example could bring good e-commerce stability to lend confidence to platform.

Google is also an excellent candidate -- they have the experience with scale and could use a strong partner like Sony to help push their home media platforms (GoogleTV, etc.)

The problem seems to be that the email validation required for resetting the password could be circumvented. There is no detailed information in the posts how, but likely either the validation hash was generated in a insecure fashion, or the email address input was not properly sanitized and allowed piggybacking (CCing) a 2nd email address to receive the confirmation email.

Being Frugal Makes You A Loser ajkesslerblog.com

I think I may already practice everything this blog post tells me to, but I still feel insulted, both on my behalf and on behalf of people I know. The author comes off as a real dick. I can't point to any recommendation in the post I specifically disagree with, but I'm pretty confident if he met me he'd find some reason to think I'm a loser. And my whole family. And most of my friends.

Maybe it's because I don't take the same snotty attitude toward the "mediocrity" of consumer purchases. Maybe it's because I recognize that the "draining" and "grating" experience of using "piece of shit" stuff is, in many cases, entirely relative. My car is less a draining piece of shit than a $15,000 car and more a draining piece of shit than a $30,000 car. My television is less a piece of shit than a $1000 television and more a piece of shit than a $2000 television.

There's no magical way to get beyond "piece of shit" when there's always a better, more expensive item available. The shirts I buy are not as nice as the $200 shirts I'd buy if I were not paying careful attention to my spending. I tried to buy a sport coat a few months ago. I'm not really comfortable buying fancy clothes, so I just wandered around randomly for a week before giving up, but what do you know, the perfect jacket I found (not in my size, but perfect fabric) at Armani Exchange cost $2000 marked way down. Apparently I will not be buying a sport coat that makes me feel "quality" and "worth it." My favorite restaurants in town easily run into triple digits for two people or even for one -- I go occasionally and watch what I spend, and on rare occasions I have whatever I want. I don't feel like I'm eating shit and reinforcing the mentality that I'm a cheap piece of crap when I spend $15 on a meal, even if I usually would prefer the $50 meal.

There's no way I can escape those compromises. There's a hell of a lot of better stuff I would buy if I made twice the money I make now. There's no way I can escape consciousness of that better stuff, and there's no way I can escape the fact that there are plenty of people in town who don't have to make the same compromises I do. There's no way I can escape the fact that the fabrics I wear do not feel as nice as the fabrics they wear. There's no escaping the fact that I chose my apartment as a trade-off between niceness and location. I have a crappy apartment in a perfect location; most of my coworkers have beautiful, new houses in distant, desolate suburbs; and a few blocks away from me there are beautiful high-rise condos that are nicer than my coworkers' houses and more centrally located than my crappy apartment. I could afford one of those condos if I stopped contributing to my 401k and stopped saving for a down payment on a house.

Does my choice of apartment make me frugal? I pay more for a central location, which is what I want, so maybe I am following his advice. On the other hand, I pay less by accepting a crappier apartment, so maybe I am not following his advice. Actually, now that I think about it, I cannot be following his advice, because my apartment does not fill me with gratification and self-esteem. Even when I make the right decisions for myself, I never think "Damn, this is great, I am so totally worth this." Instead, I think, "This isn't the best or the worst, but it's the best trade-off for me. Some people who make the same money as me will spend more and have something better, and others will spend less and have something not as good."

I really don't feel bad about it until I run into people like this who ram it down my throat that not having the stuff I really want is supposed to make me feel cheap and unworthy compared to the people who can afford it.

And finally, not that anybody gives a shit anymore, it's just morally wrong to equate possession of higher quality stuff with a higher level of worthiness. If you indulge in the gratifying thought that your nice stuff reflects your superior worthiness, that generalizes to the perception that people with higher quality stuff are higher quality people. It's an inescapable mentality, you can't not think that way, but shouldn't we be working to moderate that prejudice instead of intentionally aggravating it?

I don't think that being frugal has ever been about going cheap.

Frugality is not about consuming but investing in your life: that often contradicts with cheap.

Frugality is about not buying things you don't need but buying things you can't live without. A frugal person will typically invest in quality because he knows he'll be using the item for years and doesn't want to replace it every few.

I wouldn't consider myself extremely frugal but my favorite shoes I'm wearing today I bought in the year 2000. They feel great, they have never had to been repaired, they resist water enough, the leather is in good condition and actually they didn't cost much (guesstimate in today's currency: 100-150€). But I have this mindset that I don't need new shoes just for the sake of new shoes. That's frugality. I will wear mine for another ten years if only they'll hold together and still look tidy enough to walk into the public. (They look used of course, but still tidy.) If they don't, I'll have to buy a replacement pair.

Frugality is also sometimes buying the cheapest thing. Buying a cheap electric drill is frugal if you only drill a few times a year, which makes the drill last for decades. Buying the best that money can buy would be frugal if you're a carpenter or do renovations every week and need a professional grade durability; however, if you're not doing that you're not frugal but rather just going on the hifi tangent and in reality you want to buy the expensive model because of your ego only.

Frugality also brings focus to"I was going to say consumption but I'll say personal investment instead. It makes sense to buy quality items for what you love: if you love riding a bike then investing in a quality bike is frugal because it saves you and the environment from unneeded consumption and hair-pulling. But you can't love everything either. You can't have the top of the line computer, screen, home theater, coffee grinder, washing machine, mattress, toilet seat, motorcycle, car, bike, camera, video camera, clothes, shoes, accessories and consider yourself frugal. You can have one or two because you simply can't be spending all of your time only grinding coffee, coding, washing laundry, riding a motorbike, and shooting photos.

And yes, being frugal inevitably does make me look like a loser in the eyes of some people. But then what?

Other people's opinions about me are none of my business anyway.

I agree. Personally, I'm more sick of the culture of bargaining and haggling over increasingly small, pedestrian items that has gained a lot of fashion in the recession, even among people for whom it is not a financial imperative. It was a movement with a lot of momentum even before the recession, though, so there must be some other more enduring dynamics at play, too, not just cyclical stuff.

There's a social cost to making an ass of yourself arguing +/- $0.30 on a loaf of bread, so I don't do it. And--I jest not--I get chided by "frugal" people for not spending a half hour going through my pile of 50+ coupon clippings in front of the register in the express lane, ten people waiting in line behind me be damned.

Nobody in the startup scene here likes a customer that rides them about price no matter the discount, and appears to be fixated solely on price and not on value. Nobody likes the message that sends about the customer's priorities, their character, or the value they attach to the product or service. There is a moral and a psychological valence to the whole thing. It's off-putting, because it says that you don't realise that sometimes there is more to life than cold, rational economic calculus. So why do it to others?

Negotiating big-ticket items like salaries, houses and cars has always been okay in this culture, and there are considerable practical reasons to do it; thousands of dollars are on the line, and the people on the other end of the table have a pricing structure and a sales methodology designed specifically to maximise gains on people reluctant or unable to negotiate. Obviously, I'm not saying you should allow yourself to be screwed for the sake of eschewing confrontation.

However, at the risk of sounding culturally chauvinist, as a Soviet immigrant, one of the things I have always liked about the US and for which I have taken pride in my adopted homeland is the fact that we're above petty bazaar culture here--haggling for the sake of haggling, or being obscenely preoccupied with price. Let's not lose that. Those of us from other cultures that have fewer compunctions about wheel-dealing in petty crap know where that leads, and it's a really detestable trait when not mandated by the necessities of poverty.

I have learned over the years that not spending 'enough' on tools is always a bad choice. Like mgarfias I buy Craftsman hand tools from Sears because they really do replace them no questions asked. I know a guy that would buy beat up, nicked and dingy craftsman screw drivers or socket wrenches at garage sales for a dollar and then go to Sears and get a replacement that they would put in their toolbox.

My experience of wearing out shoes was interesting. I used to buy 'cross trainers' or whatever the 'general use' canvas/plastic tennis shoe was at Big-5 when they went on sale every year. Every year I'd get a new pair of shoes for $10 to $15 and think "Wow look how much I'm saving over buying leather shoes for like $100 - $150." And then someone pointed out that they had leather shoes that they hadn't replaced in 10 years and it occurred to me that maybe I was looking at acquisition cost and not lifetime cost.

I did the math and bought my first pair of Clark's. They lasted 7 years and came out costing roughly $11/year for those 7 years. I replaced them with the same exact model that was on sale for $75. Not only did they look better than tennis shoes, they fit better, and 'wore' better. If I added the time spent shopping, the cost to get the car to/from the Big5 every year, the Clarks were 'cheaper' by being more expensive but of better durability.

So it was still being 'Frugal' but it was being a bit more intelligent about going about calculating the costs. I've long since learned to value my time more reasonably than 'free.'

On one hand I kind of agree with this, there certainly is something to be said for buying nice stuff now and then, especially when it is stuff you love doing.

For play, I use a ratio I call the Fun Factor. Essentially, that's the $/hr of fun I get out of something. So if you go see a movie and it is $10, and it is the rare money that is actually fun to watch, then the fun factor is roughly $5.

So then you apply it to other things. Sure, $2,000 is a lot to spend a mountain bike, but divided out by the number of hours I've had on it, I'm way below $5 these days, so I consider it a fair deal.

A smartphone and laptop I love is always worth it in fun factor dollars.

That said, I do take issue on the 'lasting forever' bit, because wow, stuff just isn't made to last forever anymore and nor would you want to. I think it is a clever trick that we play on ourselves, oh, "This will be the last [blank] I ever have to buy", but how often is that really the case?

I can think of a few things I have that qualify, but they are few. I bought a $100 chef knife about a decade ago, still use it daily, still love it. I don't see my Ortlieb messenger bag ever breaking down, so maybe that's another. A few hand tools, but most hand tools last forever regardless of quality.

What are yours, what have you bought that you think you might keep forever?

I disagree.

I find this ode to consumerism quite distasteful. Sure, buy quality items if you can afford them, they'll often be worth the investment - but choosing to be frugal because of difficult financial circumstances is a good thing.

Most people don't need half of what they buy.

As for 'being fugal makes you a loser'; I think if the choice is being seen as a loser by the author of the article, and being broke and / or in debt - I'd definitely choose the former.

I'd possibly understand if this kind of rationalisation came from a government wanting its citizens to spend their way out of recession. Coming from a free thinking individual, it leaves a bad taste in my mouth.

I tend to buy in two strategies. Either so cheap but functional I don't mind throwing it out later (as eco bad as that might be), or buying good quality wares. I believe that if you can afford good quality wares, that that will both make you happier and leave you with something of substantial resale value. So it may be a better financial strategy. Compare cheap Target cabinet with "Handmade Amish Furniture."

That said, the tone of the article is well, smug and obnoxious, and makes no effort to understand that many people cannot afford the quality goods the author can, or just have different values.

For example, I use to drive sports cars and convertibles, but now I drive cheap econo-boxes. Why? They tend to be more reliable, less expensive per mile to maintain, and I drive too damn much and drive them into the ground. (And I have a poor resales strategy -- I don't get rid of the cars fast enough.) I sure do miss my convertibles. Really miss them too at this time of year. But they just had accelerated decrepitude in my hands.

There is a hidden cost to owning "lifetime" stuff- you have to keep track of it, maintain it, and ensure it doesn't get damaged or stolen. sure, having a nice tool is nice, but it is also /more work/ for as long as I keep it. The $150 'paladin tools' brand cable tracer? it's pretty nice, but I've got to spend effort keeping track of it. I've ended up buying a bunch generic of $5 'continuity testers' and leaving one at each data center and one in my car. the nicer tool doesn't do me any good if it's across town. Also, if I drop something heavy on one of these or if someone steals it? who cares.

I mean, sometimes you need the quality part to do the job, and sometimes maintaining quality tools can even be a pleasurable experience, but recognize that there is a cost to owning stuff you can't just walk away from.

I strive to keep my desktop and mailbox empty. But by no means does that make me cheap: I pay for music, video streaming services. I buy premium items and food, because I know that improving my quality of life is the purpose of having money in the first place.

The cliche but somewhat true statement is: what good is all the money in my bank account going to do me when or if I'm not around to spend them. I'd rather live a good life now than the possibility of a better one in the future.

The privilege of spending extra on "nice things" is almost purely in the realm of the well-to-do. This is the rationale Rich White People™ use when buying L.L. Bean backpacks (LIFETIME WARRANTY GUYS) that end up piled in attics and covered in dust from neglect. Also, a downside of 'nice stuff' is you have to lug it everywhere. If you lead even a moderately itinerant lifestyle, this totally blows. Don't listen to some guy on the internet telling you your stuff sucks, just buy what you damn well please and what you think will do the job. Your tools don't make you great, your skills do.

For mattresses buy pocket spring or latex foam. When me and my girlfriend switched to pocket springs we literally felled asleep the first time our heads touched the mattresses ... in the middle of the day, right after we set it up in our apartment. It's incredibly comfortable.

For shoes buy some trekking shoes with goretex membrane. You'll never have wet feet in your life again. My Garmont's served me well for last 8 ears. I just had to do minor adjustment year ago because soles have rubbed off not evenly. And I am yet to find shoelaces that don't break. I think about the ones made of kevlar. Before that I was buying sneakers and leather shoes that fell apart after 0.5-1 year and had to watch out for every puddle.

For your torso buy something from Polartec, as thick as you can find. And something thin, light breathable, waterproof and windstopping to wear it when it rains. Again you'll not get wet from the rain and dry up as fast as if you were wearing only t-shirt.

Always spend money on things that make you life easier or the things you have to do more comfortable. But when you don't have idea how good are the things you consider buying are always pick cheaper ones. High price never guarantees quality. It's often even strong indicator that seller is dishonest.

Oh. And don't make stuff up and don't buy things that will require from you doing additional things.

I also almost never bring damaged things to the store to have them replaced. It's easier to toss it away and buy something else. Much less unpleasant social interaction.

I kind of agree with the author about willing to spend big money on things that matter. Mattresses, computers, chairs, desks, things like that are all things that you use regularly.

Though that's now that I consider being Frugal. Being frugal is not only being practical with my money (buying what I need and knowing what I won't use). I had a strong desire of buying an iPad, but really I know I won't use it. It also involves making sure I take care of my things, I check my tires and oil on my car regularly. Doing the little things to keep your stuff going and not spending frivolously is being frugal.

There are studies that indicate that runners wearing $100+ shoes are much more prone to injury than runners wearing sub-$50 shoes. In fact, what's initially "comfortable" insulates our feet from important physical signals, leading to a lot of physical pain. (read the recent, excellent book "Born To Run" if you find this interesting)

My point is that not thinking about decisions "makes you a loser", and equating price with quality is often a mistake.

Being cheap just for the sake of being cheap/frugal if the cost is not a constraint is not wise and often times produces little to negative return. Additionally, if the price tag is the only thing you are looking at and considering when buying something, you are most likely overlooking equally important costs down the road.

It seems people who are frugal/cheap fall in to a few categories:

* Little income and need to maximize runway

The best way to maximize your runway in this case is to reduce monthly/repeated expenditures, especially food and housing. Being frugal here is not only logical, it's a must.

* Saving for the long-term

Although you will net a bit of money this way over the really long-term, it's far more efficient and gratifying to figure out a way to disconnect your income from the the amount of time that you put in to making that income (e.g. making a smart investment with a high rate of return) in order to maximize your savings. Most people simply do not spend enough to see large savings through being frugal, at least not enough to significantly change their economic standing.

* Gaming factor

Some people just like the gratification of having gamed the system, which is understandable.

* Mental cobwebs

It's often the case that people who grow up poor are far more price conscious despite their current economic standing.

It's simple.

Just count the number of hours you use an item in a week. Anything you use for a large part of the week should be of high quality.

Bed, office chair, desk, computer screen, computer, cooking utensils if you cook a lot, phone - in my case.

My car is 10 years old and doesn't have an a/c but I use it irregularly for Kiteboarding purposes and don't care.

In essence, it's much harder to bear a small pain for a long time than it is to bear a big pain for a small amount of time. And the mental stress from the smaller and longer pain is much much more IMHO.

AJ is saying don't cut spending on things that affect your production. That's absolutely a no-brainer. Buy yourself good tools, ensure you get good sleep, keep your health up, keep your ability to walk.

Always spend more to increase your production by a bigger amount. It pays for itself in the end.

Now, how much should you cut on pure consumption? That's a tricky one. I tend to cut my consumption as low as I can without hurting my production. But do always spend well on tools, on getting your production up, on your health, and on taking good care of people who do right by you. Absolutely don't go cheap on that stuff, you wind up with less in the long run if you do.

I think it's perfectly acceptable to buy a cheap version of something if you're not sure how much you're going to be using it. For instance, if you decide to take up guitar, you'd be an idiot to spend $3000 on a nice Fender Stratocaster, because chances are you're going to play it for a week and then never touch it again. Same goes for a lot of hobbies. If you are going to use something a lot, however, I agree that you should eventually upgrade to the nicest stuff you can afford.

Obviously this article has hit a nerve. Its true, the tone is somewhat rude and I don't agree with all he says, but I'm happy about the discussions. I'm a cheap bastard and so are most of my friends. But I used to be the cheapest. Hell, in my climbing bum days before Uni, I even got called "cheap bastard" by fellow climbers on the campsite!

However, I'm changing. More into the direction that the author proposes. This year, I got a Mac. It was almost forced on me by a friend. I always liked Apple products but thought the price/value was just not good enough for a poor student. I think I was wrong. I never want to go back. I would probably clean toilets to afford a Mac if I have to.

The author touches an important point, especially for aspring entrepreneurs, when he says:
"Using well designed stuff reinforces the mindset of earning and creating. “Man, the world needs more well designed and well made stuff like this.” “Man, I'm going to earn more so I can have more well designed and well made stuff like this.”"
I couldn't agree more. How can you get costumers to buy quality from you if you don't choose quality over price in your daily life? Its hard to build something, that you have no experience with.

One advantage of buying cheap, though, is that its easier to get rid of them later. Hence, you might feel more freedom and flexibility. However, I'm starting to pay attention to aspects like weight and robustness so I don't have to leave them behind when I leave. What I really want to get rid of the next time I move is all the cheap stuff. On the other hand, having lots of cheap stuff is a good reservoir for hacks!

I also agree with the author on "The mental aspect [being cheap] is huge."
I'm trying to get rid of this problem, too. In the last month I've bought two free Apps [1] on online stores. I just felt they were worth the money. Later, when I learned this was actually true, I checked for the license and was pleased to see they where under GPL and Apache 2.0

The surest way to be happy is to have a large safety net in all the things you really need.

You can skimp on the things you merely want, and still be happy.

Think of all the things you really need, the things you would be really miserable without. These are the ones you should splurge on. I mean, really, spend 2x as much as you think the average person would spend on them. Totally own it. Then you will always feel like your life is good. Because you don't sweat the small stuff :)

I've heard of an idiom "expensive is cheap" (kinda reminds you of "less is more").

The idea being, or rather my interpretation of it is: something of high quality that's 2x the price of something else of low quality is probably wroth 10x more, so it's actually "cheap" in the sense that you get a lot more than what you pay for.

One of the keys in all of this is differentiating between "cheap crap", "cheap crap with a big price tag", and "expensive but worth it". I recently went shoe shopping. I was looking for a pair of comfortable, casual shoes. What I came across were:

$50 bunch-of-choices, made in China

$150 Boss/Diesel/etc, made in China

$225 Mephisto, made in France

$325 Ferragamo, made in Italy.

There is one obvious "wrong" choice here, yet it's the one that many people end up with when they think they're going to "buy something nice".

There are two points here - the practical one (don't buy cheap stuff, you save money but it costs you time because it doesn't work as well, breaks and causes more grief than it's worth) and the mental one (because you're worth it).

The first one is fine and bang on the money, but are people actually getting their sense of self worth from the quality of their nail clippers or having pot pourri in the bathroom? Seriously?

If that's really the case then I'd suggest that people look at the underlying issue of why this is rather than papering over the cracks by buying nice stuff. The idea that your self worth comes down to your stuff is horrible and should only be true in the world of advertising and marketing.

One thing I do is to allocate a bit of money each week to "lifestyle", This is the amount of money you allow yourself to waste every week. In my case it's around $25.

Situations to use it:

* Treat myself to a $10 lunch instead of a $5 one once a week

* Just pay for parking instead of driving around of 10 minutes looking for a free park.

* Catch a Taxi instead of walking or waiting for a bus

* Want a coke and the nearest store charges $4/can? just pay it rather than spending 10 minutes looking for a more reasonable price.

* See a cheap toy or a book that looks interesting. Just buy it.

Depending on how rich you are it could be more or less than $25/week. Somewhere between 0.1% and 1% of your income perhaps.

Wow, this guy is a loser.

I don't disagree with his suggestion that the primary tools you use in life and your trade should be high-quality. He's right about that specific statement. If I must eat a Ramen-equivalent to buy the tools I need, I will. However, most of us cannot afford his tastes in every area of life after paying for crappy health insurance, a mortgage, and children. He reads like a child who has never been forced to live on less and to value the tools we have.

Most normal people are aware that every purchasing decision we make involves trade-offs. We perform a cost-benefit analysis with many purchases. We think, if I cut back on buying fancy coffee over the course of a year, I will save up enough to afford a better laptop or a lower health insurance deductible.

The author has issues that need to be addressed. The whole article reads like someone rationalizing bad choices on luxury-branded products and criticizing in advance anyone who may one day point them out.

There is a difference between cheap and frugal. In accepted parlance "cheap" means making purchasing decisions based solely on price. "Frugal" means paying for value, which is what this post is ultimately recommending (despite the title) - a "lean" mentality, where you avoid needless cash burn (or saving) in favor of those things that really matter.

It's easy to say "spend $30 extra" when you actually have that money. There were times when I was in debt, and had like $10 on my bank account, and so many personal problems I couldn't handle work. His advice was pointless at the time. That advice is pointless for anyone who doesn't have free $30 to spend around.

My verdict: the author lives in a bubble that he has created and paid for. However, that bubble is also his prison; it suppresses his ability to make sudden changes in life.

I am fairly ok with sleeping on the street, since I've done it a number of times, so when it comes to making a mildly life-changing decision I'll be more confident about taking a risk.

Look, I like sitting here in a nice couch, typing on a Macbook about how hardcore I am, just as much as everyone else does. But ultimately, a nice couch is just that -- a nice couch, and a candle in the bathroom is just a fucking candle. And in a hundred years, no one will care if you had a nice couch or a candle in your bathroom, but they will if you wrote a book or created something beautiful.

What is Frugal is subjective to your income. What makes a person feel good or bad is consequential of his social circle and what his friends/acquaintances have.

For eg: a person making $1 million a year, could buy a $40K car and feel like he was not compromising if all his friends had $30K cars.

However, a guy who is making a similar amount of money might not be too happy if he had to buy a Jag and all his friends had Ferraris.

Ignoring the whole loser argument that the author is making, the one good thing to consider here in the article is, its a good idea to spend proportional to the time you will be spending with the product.

For eg: If you are spending a lot of time on computer, you probably want to get something that is "good" quality and which is good for your eyes and has other benefits.

I'm not sure I'm sold completely on the need. It's a very cool idea, to be sure, but I'm confused at the role it fills.

My knowledge of disaster zones is limited, but for military deployments - the other major customer - it's pretty in depth.

Here's the thing, there are two classes of structure, basically: Temporary and Permanent.

For a temporary structure - even longer term - a modern, modular tenting system (such as TEMS: http://www.mandbmag.com/tents/index.html) has this beat hands down in pretty much every way. Lighter, faster setup, faster tear down, adaptability, etc.

For a permanent structure, seriously? It would be much easier to build a traditional wooden structure once you've decided that you need one. You could even put the locals to work (which they would need) doing so. I find it very difficult to believe that anyone would want one of these dingy, musty things over a proper wood or concrete framed construction.

So where exactly does this fit in the spectrum? I'm not sure it does.

This reminds me of the very cool class I took at Michigan. In 08, our design challenge was to design and build an easily shipped, carried and deployed station for disaster areas that facilitates bathroom functions, washing and showering. The product criteria included that it:

Must be free standing and use no external power source.

Must allow people to go to the bathroom, wash one's face and hands, bathe an infant and bathe/shower an adult.

Must have a safe, easily executed waste removal and transport system from the bathroom facility. All waste must be easily removed and reliably sealed off from the local environment as it is transported elsewhere.

Must weigh less than 40 pounds and pack down for easy transportation.

Must manage gray water from the sink and shower, by directing it to a hose connection.

http://www.tauber.umich.edu/News%20and%20Events/IPD/2008/ind...

We had a cross disciplinary team (engineering, design, and business) and had to actually build the product, and were judged based on profit... how many "purchases" were made at a fixed price ("purchases" were made by designers around the world on the web and in person at a live show) minus costs (we had to cost out the thing at scale). It was amazing and we ended up winning (I was part of the "cocoon" team).

If you can get a chance to take a class like this, do it. Definitely do Integrated Product Development if you're at Michigan!

One of my mentors in Grad School (the late David H. Crane, FAIA), got a grant to design an emergency shelter right out of Harvard GSD. He and his team spent months designing a precast concrete building which could be deployed and erected quickly. At the end they did the economic analysis of the fabrication costs. The only place where it was economically viable to build it was lower Manhattan (this was back in the early 1950's).

This design suffers similar conceptual problems: diverting potable water to make a concrete structure when a tent would serve adequately - one of the biggest problems early in a disaster is providing potable water in sufficient quantity to maintain sanitation and provide adequate hydration for the local population and aid workers.

If, for example, the tent is not fully inflated before the concrete is added, would the hardened building be structurally compromised?

Although I find this fantastic, I also find it quite odd?

I think his attitude is fantastic for someone who is having their apps ripped off, I find it strangely odd that in the comments people think this is the attitude that developers are meant to take when their work is ripped off, humbled.

I purchase all apps from the app store, I had Cydia but I took the jail break off my phone. I think the 59p - £3 for an app is nothing for all the hard work that has gone in and I am more than happy to make the purchase.

I think the whole episode has been strangely rewarding for him but again I think it makes people think that all developers should have this attitude. I think it's funny that in the comments that someone said that developers should treat all consumers with positive and constructive humbleness. I'm sorry but the meaning of "Consumer" is "A person who purchases goods and services for personal use". There is a keyword here, "Purchase".

Kudos to the guy for some great PR but I really hope that all "consumers" don't get this mentality when trying to rip off apps

If we're going to open a new dialog on this:

Has anybody noticed the drastic decline in quality of links and comments in the last month or so? I think one of the problems is that, without comment scores, new users don't have feedback from the community on how they're supposed to act. There's no way for them to learn the culture.

So it's September, but with no way to tell the new students to mind their manners.

On the issue of scores vs no-scores, it'd be possible to A/B test this, so half of HN users see scores, and half don't.

Metrics to track might include the number of comments made, number of hits on the site, number of upvotes / downvotes, and probably many more.

Some people obviously feel strongly about this issue, and it might be necessary to take steps to prevent gaming of the outcome. Keeping the metrics secret until after the test would help with this. So would publicly announcing that only a small (say 10%) but undisclosed subset of users will be used to determine the outcomes of the testing. So any individual user wouldn't know if their behaviour would affect the results, and so would have little incentive to waste their time trying to affect the outcome.

It'd be nice to take a data-driven approach to resolving this question.

Yeah, having got past the initial "ooh, this is cool" phase, I do actually think HN was better off with the comment scores.

For example, I was looking at a popular submission the other day and someone had said "Hey is there a PHP port of this?". Back in the day, I'd be able to see how many points it had as a rough indicator of how many other people would have found a PHP port useful. Now I can't tell if that was just one guy, or if 50 people thought the same.

Please, PG, bring the points back? (and while you're at it, stop new users being shown in green?)

The submitted site is interesting. I will not go to the trouble of contributing any scores I am aware of to the database, however. Here in this thread, we are once again in metadiscussion about whether or not it was a good idea for HN to experiment with not showing users the comment karma scores of other users, a change that happened not long ago. When pg wrote his post "Ask HN: How to stave off decline of HN?" just 47 days ago,

http://news.ycombinator.com/item?id=2403696

he wrote, "The problem has several components: comments that are (a) mean and/or (b) dumb that (c) get massively upvoted."

That's still the key issue. In the view of the site founder, who has had a registered account here for 1684 days, many of the high-scoring comments carried a false signal of quality, likely to mislead users about which comments are factually accurate or helpful to the community. If some change of voting rules or comment karma visibility brings about higher scores for good comments, and lower scores for mean, dumb, or other bad comments, that is helpful to all readers of HN.

Feel free to review the site guidelines

http://ycombinator.com/newsguidelines.html

and the site welcome message

http://ycombinator.com/newswelcome.html

for guidance on what is desired here and thus guidance on how to vote. I defer to the site founder on all issues of site governance. I have found HN largely to be a worthwhile website for my 914 days as a registered user, and my interest is mostly to make sure that the site founder and the members of his volunteer editor ("curator") team

http://ycombinator.com/newsfaq.html

continue to enjoy the site and find it useful for themselves. They are doing a good job, and I want them to have incentive to keep up the good work. On my part, I have been able to find good comments more readily since the comment karma scores were hidden than I was before.

I much prefer the new HN, without visible comment scores.

When comment scores were visible, it was obvious that many people would just vote with the herd, downvoting comments with lots of downvotes, and upvoting comments with lots of upvotes.

This is still a problem, since HN still tends to put highly rated comments near the top, and low rated comments near the bottom. But it's not nearly as much of a problem as it was when comment scores were visible.

I think the quality of comments has increased with the new system, and I find myself reading more of the comments now that the scores aren't visible.

I also find myself voting less, and voting only on comments I personally feel are exceptionally good or exceptionally bad.

One change I would like to see HN experiment with is making the score of a given comment visible only after you've voted on that comment.

This will both encourage voting and also satisfy people's curiosity, while still discouraging voting with the herd.

Typing is kinda difficult for me on most days, so I don't comment much.
I vote a little bit on comments, when I bother to read them, but I tend
to vote-up more on submissions. I've also have been known to do a lot of
flagging on the /newest queue (and even triggering the "excessive
flagger" threshold).

I do try to remember to make new submissions for all to enjoy, but the
irony is, this means I'm off somewhere else looking for interesting
stuff rather than finding it here. The stuff that I find interesting
is new tech, engineering, security and science developments (i.e.
hacking up new solutions and analysis) along with a small splattering of
business.

The speed of churn on the /newest queue means some of my submissions are
not even seen. On average, there's maybe two or three other people here
with similar interests to mine, or better said, they appreciated the
submission enough to up-vote. But that is on average, so plenty of my
submissions vanish into obscurity with no notice. --This is not a
complaint. Other people have other interests, and the fast queue
progression should be expected when there is no barrier to entry.

The trouble is, the fast queue means submitters get very little USEFUL
feedback. If you post some link-baited controversy, getting 1000+ points
on the submission is not too unusual, but it probably isn't noteworthy
new hacking. The good hacking stuff on HN seldom hits the main /news
page, instead it's buried deeply in the /newest queue. --It has always
been like this. Blame human nature. If you look at /classic or do some
HN spelunking by item?id= or hit archive.org for old snapshots, you'll
find the main /news page has neither improved nor declined.

I think gaining points for submissions is unfair. In my opinion, I think
a submission just says, "Hey, I thought this was interesting, and you
might too." When a submission is sincere, it's just a friendly gesture
with good intentions. But we all know how good intentions work. Whether
or not the submissions is ever seen by others here, or more importantly,
is interesting hacking to them is generally unknown, even to the
submitter. The displayed up-votes on submissions are really just a
popularity contest feeding on link-baited controversy.

Another reason why gaining points for submissions is unfair is a
submission has vastly superior visibility compared to a comment. I
believe PG has some secret sauce running to address the visibility
discrepancy. As far as I've been able to divine through observation,
points from submissions don't count towards the "average" listed in your
profile. Well, it seems that way on my account, but I think even older
and more active commenting members (grellas) may have their average
calculated with both submissions and comments. (Don't get me wrong, when
grellas posts, I read it, and usually up-vote. I doubt I'm alone on that
so his exceedingly high average might be warranted from comments alone).

So the display of points on submissions fails to be particularly
valuable metric. Similar could be said for the display of points on
comments. I refuse to care what other people think of you or your
statements, and I would prefer avoid being biased by displayed points so
I make up my own mind on whether or not I find your comment interesting.

For notes, it was tptacek that made the suggestion to remove the display
of comment points in the "Stave Off The Decline of HN" thread from PG. I
thought his idea was brilliant, possibly because I had the same idea,
but as usual, tptacek thought of and posted it first. If you want a
discussion to be useful, turning it into a game is entirely
counter-productive. Worse yet, the display of points creates an unfair
game due to manipulations of visibility, cognitive bias and other
factors.

Since the removal of comment points being displayed, there has been far
less one-up-manship in the discussions, and people are more polite
because they are not competing for points in a game. You are now more
free to just state your opinion without worrying about whether or not
others will agree or disagree with you. As long as you're not being an
ass about it, you can generally post uncommon or even controversial
opinions without repercussions.

Some have (repeatedly) argued that the lack of displayed comment points
results in a loss of context or loss of a valuable metric for deciding
what is worth reading. I'd argue the opposite (and slightly less popular
view) that displayed comment points fail to offer any real usefulness
and are mostly harmful. --Just like whether or not my submissions are
interesting, the usefulness of displayed comment points is a very
subjective matter of opinion. Some find it helpful, but others consider
it harmful.

To you, my opinion about comment points does not matter. You already
have your own opinion. And there is the very reason why displaying
comment points doesn't really matter
.

In my view, the comment scores made the site more fun and more social.

One thought is that maybe the score gets hidden if it is 1 or less. I think that scores are especially interesting when it highlights a great comment or provides feedback to the person making the comment.

The ordering of comments without a score is a good example of why a visible score is needed. You assume that the best comments are on top but it is not clear how good are the comments below the top one.

Since the scores were removed, I have been commenting less often and often ignoring many of the comments below the top ones.

Science says that blind crowdsourcing is generally better: http://www.wired.co.uk/news/archive/2011-05/17/wisdom-of-cro...

One could find arguments for both sides, though:

- HN is not a crowd, it's a niche community

- Voting is not blind even now.

- The number actually encourages voting, since it serves to remind that your vote will change than number

- It's good to know whether your vote will have little impact or will move the comment upwards

- The site should encourage more people to vote, the more people vote the better.

spottiness 2 days ago 0 replies      
There is a huge asymmetry in the power of HN users between those that can down-vote and the rest. The problem is that many of the "powerfuls" use their privilege to punish other users based on disagreements, whims, or simply to silence opposite opinions. It is OK to indicate the popularity of a comment by moving it to the top but it's wrong to silence an unpopular comment by fading it away. That should be reserved only to comments that violate the rules: spams, trolls, shameless ads, etc.

Put the unpopulars at the bottom or indicate the degree of popularity with a number, but don't disappear it. Fading away honest unpopular comments is a big turn off that ultimately harms the debate.

Goodness and badness is subjective. Up/down voting should exist only for the purpose of recommending articles to each individual user. This is far different from the typical use of up/down which is to recommend articles to the collective, which is not robust against influxes from other communities, e.g. reddit, digg etc.

In other words, when I log in, I should see my own personal HN list of stories, that have been submitted by people I respect (i.e. people I've previously upvoted), or people that they respect etc.

I call this idea PeopleRank.

I was relieved when the scores disappeared. The less unnecessary information the better, I find. Besides, I think score visibility just promotes groupthink.

I don't use score sheets with my friends. Moderation becomes necessary in a pseudonymous environment, but there's no reason for it to become visible where it's not necessary. Reply-order shuffling and grey-out seem to be a pretty good fit there.

I guess I don't really get the point of this. The whole idea of ditching points was to see if it could generate better discussion. By using this extension you are re-enabling points (even if only for a few select users). That re-enabling is going to encourage those users to go back to their bad posting habits... or so we would assume if the original theory that points cause bad posts is correct.

I know a lot of you love your points, but maybe we should see if no points really does generate better discussion rather than trying to find a way to create a point system.

PS: I think points is really tricky, it rewards people for great comments, but it also rewards those stupid-one-line-no-thinking comments. Maybe only show points for comments with more text... whatever, thats a whole other subject.

" If the response is never received, or if there is a redirect, then a DNS request for dns.msftncsi.com is made. If DNS resolves properly but the page is inaccessible, then it is assumed that there is a working internet connection, but an in-browser authentication page is blocking access to the file. This results in the pop-up balloon above. If DNS resolution fails or returns the wrong address, then it is assumed that the internet connection is completely unsuccessful, and the “no internet access” error is shown."

Would this mean that DNS poisoning msftncsi.com would prevent Win7 machines from accessing the internet? Or would this merely cause the 'no internet access' error to be displayed despite your connection working anyway?

The iPhone uses a very similar technique. If you connect to a wifi network that requires login, a browser sans address bar will pop-up over your current app and allow you to login. Once an external resource can be reached, the browser disappears and returns you to the previous app. Steve Jobs even alluded to it / bragged about it when the iPhone was first unveiled, 2 years before Win7 was released.

Yes, I have wanted to build something like that for Android, mainly to keep my phone from getting confused when it's connected to someone's wifi that demands some check box be checked off for service.

It would periodically awaken, see if the wifi is connected, if it is is there connectivity, if there is, go back to sleep, if there is not, turn the wifi off.

I've also wanted to build for Android the same piece of code, but if for 2 or 5 urls it gets back the same page with a checkbox, it checks off the box and sends it back off.

But I am curious, do all those wifi dns terms and agreements hijacking pages break any sort of RFC?

And is there any solution in ip6?

Or is there a real fix possible in ip4?

The common OAuth flow inside a mobile app is to show a web browser dialog which loads Webkit/IE/etc and show you the Twitter log-in UI. Frankly, I have no idea how to verify this page is actually Twitter's UI - there is no browser chrome, no SSL lock icon or any other trust indicators. It could as easily be just a random dialog constructed by the app author. I just don't see the value-add of OAuth in mobile app scenarios. Note that xAuth doesn't mean the app stores the passwords - you store a token like in OAuth. Of course, whether the app developer can be trusted to not store the username/password is a different story.

Btw, I have a popular WP7 app which uses xauth, primarily because Twitter's login screen is broken on the Windows Phone browser.

jrockway 4 days ago 7 replies      
I'm OK with requiring OAuth. It's hard to trust third parties with data they collect themselves: see Sony and Gawker. It's even harder to trust them with data that belongs to someone else: they might one-way-hash their own passwords, of course, but they can't do that to your Twitter password. It's probably sitting in a database, cleartext, for every rogue employee or cracker to see.

Even if you don't care about someone having your credentials, you can't trust them not to intentionally or accidentally misuse your account. The only way to trust a third party is to give them an account that can only perform the actions that you specify, and that's exactly what OAuth does. Of course you have to use Twitter's site for that: that's where the trust comes from.

Anyway, I've used Android apps that pop open a web browser for the authentication part and then return you to the native app. It's, by definition, not seamless... but it's not confusing or slow or difficult or annoying. I imagine the experience is similar on iOS and Blackberry. So I don't see a problem here: all I see is the ability for users to have better protection over their personal information. That means they will be more willing to try your product, because the damage it can cause is limited. Less risk, more opportunity for innovation.

Hardly a "shit sandwich".

Not sure if this would break some TOS or something but can't a native app just continue asking you for your username and password and just do this oath stuff in an offscreen webview, making it seem just like with xauth? It's almost disingenuous to show an in app browser with oath and confuse the user into thinking he has the same sort of "same origin" security as oath in the browser -- he doesn't, that webview is completely controlled by the app and thus offers no additional security over xauth whatsoever.

As many others have pointed out, OAuth is extremely susceptible to phishing or snooping of passwords on platforms where the OAuth flow is done in an embedded web view, which can be considered "untrusted", vs. your browser which could be considered "trusted" because you know the URL bar is accurate, and there's no mechanism for 3rd parties to scrape passwords (well, except for user scripts / extensions)

OAuth does also remove the burden of securely storing passwords, but so does xAuth.

At what point is someone going to just say "fuck Twitter, Inc." and create a library of simple web-scrapers that emulates most of the API that twitter has been trying to claw back from the third-party dev community for the past year via the standard http interface? Such a library may be brittle, but it can't be much worse than the "yeah, we told you to do this a couple of months ago but now we changed our minds and you have two weeks to comply with our new policy" status that exists now?

It's clear that Twitter wants to move innovation in their ecosystem away from native clients that duplicate their exiting functionality. Instead they seem to be keen to support projects that offer innovative ways of displaying, sorting, or working with Twitter's firehose.

Instagram does something similar. Their API terms of use read:
"You cannot replicate the core user experience of Instagram.com"
(http://instagram.com/developer/)

I guess it is a matter of keeping potential future monetization options.

The last time I looked xAuth was not available for everyone. You had to request access to it and they often wouldn't give you the access.

I didn't get xAuth for my apps so I had to go the OAuth way. And I believe only a few popular apps got xAuth.

Yes! I'm glad finally someone like Gruber shared his opinion on this. Integrating Twitter in native apps has been a huge pain for me and trying to explain clients why they can't have a native branded user/password dialog in the app (like "all" the other apps) is really tedious. For such a big player like Twitter they made it really cumbersome for 3rd partys to do simple tasks like posting a tweet.

Browser-based OAuth flow (like Facebook's new iOS SDK -- the one that avoids using embedded webview) has two advantages:

1.) Single sign on. If you're already logged in to the site in the browser, you don't have to enter your user/password again. Also, if you don't trust the app invoking the web browser, you can always exit the app and pre-login to site with the web browser before running the app again.

2.) Optional interstitial pages. Sometimes, your account may be accessed from some questionable location. The OAuth flow enables challenging users with additional security questions before giving authorization to the app (e.g. Facebook's identify-your-friends'-faces challenge, enter-your-birthday challenge, etc.)

The biggest issue with Twitter oAuth sign-in that we have faced as developers is that the Twitter sign-in page does not work at all or is not optimized for feature phones with smaller screens and not running Webkit based browser. Always wished that Twitter provided a URL - twitter.com/appname that users could go to and assign all permissions and got a simple key + PIN that they could enter in our app to access their tweets.

It is bad to use a bunch of the user's CPU without any notice. They will probably notice that your site makes their computer slow and never come back again. Also, once they find out you've been using their CPU power/electricity/battery life surreptitiously for private, unshared gain, you will probably have some angry customers.

Additionally, does this automatically hook in to slush's pool or something? Bitcoin mining is practically useless on CPU; even the fastest CPUs out get way, way less than 10mhash. The average length of time to find a block at 9999khash and current difficulty is 1200+ days, so even that estimate is over-optimistic, so this isn't worth anything if your users don't sit on your site for 5 years+, unless it's hooked into a pool or some other contraption to pay on shares instead of blocks.

Javascript is way too slow compared to GPU, by at least a factor of 1000 or more. If you have 1M daily unique visitor and you manage to "steal" 10 CPU seconds from each of them, the amount of work would be equivalent to 1e6 * 10 / 1000 = 10000 seconds which is about 2.8 hours of one dedicated GPU-based mining machine.

Cute, but this is hardly worthwhile unless you have a massive number of users, in which case you probably don't want to piss them off by wasting their CPUs.

I'm getting about 13K hashes/sec with this JavaScript miner. For comparison, my GPU gives me 100M hashes/sec, and even my 12 CPU cores give me 10M hashes/sec with the official Bitcoin client.

So you'd need about 1000 concurrent users at all times to match a single machine. EngineYard SHA1 contestants who used this approach had the same problem.

Now, if Native Client was widely deployed, or you could somehow rig up WebGL...

If there is a Bitcoin bubble you can be sure that there will be people doing things like this, regardless of whether it's ethical or not. From the site visitor's point of view they're not getting a cut of the mined coins, so their high CPU usage is purely a waste and annoyance. If widely deployed, this sort of browser based CPU wasting enterprise could bring Bitcoin into disrepute and be an excuse for governments to treat it as a cyber-threat.

PluraProcessing.com pays site owners to farm out computations to their clients. According to PP, site owners can make about $2.60/month/user. The major catch is that the system only works well when visitors have long visit durations (e.g. web-based video games). I presume PP necessitates long visit-durations because short visits won't yield enough computational resources to make computations economical.

Someone could make a URL shortening service that frames sites, including the mining JS. Users could sign up and get a % from the mined coins on links that they share.

As many people are pointing out that GPUs are faster for mining that CPUs, would you be able to make use of a GPU with WebGL (or GPU-accelerated Flash)? I guess the GPU computations don't fall in the spec of WebGL though.

This is a neat-trick, and I ♥ Javascript, so even better.

In terms of ramping this up to actually be a viable revenue source... I guess you'd need a browser plugin which was hard-core about making sure you agreed to usage, and verified to the server that you were actually doing the mining you'd agreed to - and that could tap in to the GPU.

But then, if Bitcoins become worth something meaningful, wouldn't we all be using our GPU most of the time to be generating them anyway? In which case, the website starts asking you for the opportunity cost of using your GPU instead, and you know how much that's worth, and boom, micropayments.

There is already Freenet which had/has similar ambitions.

The problem with this stuff is that immediately tossing all the possible anonymity features onto to your app makes it so utterly seperate from the net that you can't get a critical of mass interest (and your speed really bogs-down but that is secondary/solvable).

What I'd like to see instead is something like an escalating series of counter-measures that each user can trigger at the point they're cut-off from "ordinary" communication - alternative dns when regular dns is messed-with, alternative pipes when they start filtering ordinary sockets, etc.

But make it one app that initially does simple for the user so it get widespread but with the proviso that the apps would do enough discovery that you could "go stealth" when the time came - and have the apps be doing discovery in the meantime.

Attaching MAFIA-Fire to a "social sharing" app like "tribler" http://www.tribler.org/trac seems like a start.

Might work for piracy but unfortunately it looks like they punted on issues that would help use by activists. Design assumption #1 (white paper section 3.1): "The traffic of every node in the network is assumed to be eavesdropped on (individually, but not globally in a fully correlated fashion) by an external party."

A state-level adversary can instrument their major ISPs, put a bunch of nodes on the network, push traffic through the network and do analyze the resulting traffic. Once they figure out who they want to question it's pretty simple, the mere presence of the software on your computer would be incriminating.

I think right now social networking sites are the best game in town because they have legitimate non-activist uses so they won't automatically get you in trouble. To improve on them resistance to traffic analysis and on-client footprint both need to be dealt with or the tool needs to be really popular for some innocuous application.

It is a really interesting set of problems though.

The whitepaper is an interesting read. The "large data throughput" bullet-point is justified by the claim that no intermediary forwarding node has any idea whether it's talking to another intermediary node or the one of the actual endpoints. So once you have a buzzing network of anonymized nodes with large volumes of anonymous traffic, you can open up a direct connection to your buddy and transfer at high speed. Later, you can claim with "reasonable doubt" that you couldn't have possibly known whether or not they were a forwarding node or an endpoint in that conversation. (You can also claim that you didn't know whether or not YOU were a forwarding node!) This seems reasonable to me so long as you're transferring at a rate comparable to the average throughput, though I'm not sure how you could determine that.

Well, I'm not really familiar with this sort of distributed scheme, so that might be old hat, insanely insecure, or what have you.

This seems like an interesting idea/solution to one of Internet's issues.
The challenge however is how do you persuade enough people to start using it? And then the more people use it the more important it becomes and people just won't stop using it.

Facebook is a typical example of how important is to have people adopt a technology. Prior to Facebook was MySpace, yet the former managed to impose and finally replaced the latter because more and more people started using Facebook. With Twitter it's pretty much the same adoption process. Because most people into micro-blogging use it, it is now virtually impossible to come up with another micro-blogging platform that can replace Twitter. And the conversation could go on forever with countless examples.

I'm sure there are so many great ideas out there that get wasted just because people won't start adopting them.
