Why I Like Go github.com

These points are all very true, and I admit I haven't done more with Go yet than play around. But there are a few reasons I feel I don't like Go, or at least, there are warts that will probably limit how much I'm going to like it.

Nil pointers are #1 on that list. Tony Hoare called them a "billion dollar mistake"[1]. In Go, as in C, C++, or Java, any pointer can be `nil` (similar to `NULL`) at any point in time. You essentially always have to check; you're constantly just one pointer dereference away from blowing up the program. Since ways of solving this problem are known, I find this hard to swallow in a new language.

Compare Rust where, unless you have explicitly used the unsafe features of the language, all pointers are guaranteed non-nil and valid. Instead of a function returning a nil pointer, it returns an `Option` type which is either `Some ptr` or `None`. The type system guarantees you have considered both possibilities so there's no such thing as a runtime null pointer dereference. Scala has a similar `Option` type, as does Haskell, calling it `Maybe`. In 2013 I don't want to still constantly check for a nil pointer, or have my program blow up at runtime if I forget.

The second disappointment is that when I looked into it, it seemed there are ways to call C functions from Go code, but no working way to call Go from C code. Maybe that wasn't a goal at Google, but it seems like a missed opportunity. As a result, you can't use Go to write an Nginx module, or an audio plugin for a C/C++ host app, or a library that can be used from multiple languages.

I think there is a real unmet need for a higher-level, safer language you can use to write libraries. Imagine if zlib, or libpng, or the reference implementations of codecs (Vorbis, Opus, VP8) could be written in something like Go. Or spelling correction libraries. Currently we have two tiers of libraries: those written in C/C++, which can be used from any language under the sun (Python bindings, Ruby bindings, Perl bindings, PHP bindings...), and those written in high-level dynamic languages (Python, Ruby, Perl, PHP, ...) which can only be used by the same language. We need a middle ground. C isn't expressive or safe enough to deserve to be the lingua franca like this. And Go is tantalizingly close to replacing it, but not quite.

I would like to add one other thing I like about go: There is a parser and an abstract syntax tree in the standard library.

Sometimes when I'm programming at work I need to add log messages to every method on a large interface (or several interfaces). It is obvious to me that there needs to be some tool or library that adds these very simple log messages to these methods for me (like "Entering method getUser(UserId=2701, SessionId='AABCF')").

The tool we have at work uses runtime generated code to add these messages to methods automatically. Besides the performance hit this is fine, except for one problem. Sometimes it doesn't work; and it is impossible to figure out why. You turn on the tool, add all the right metadata, and nothing happens. You could argue that it is a tool problem, but I think one of the big things is that runtime generated code is just vastly inferior to compile time generated code.

If I were using go, my tool would open the code, read the interfaces, and spit out a nice implementation of logging in a .generated.go file and if it doesn't work for some reason I can actually go look at the generated code and see why. Trying to figure out why an implementation isn't working by looking at it's dynamically generated bytecode or .net clr is not fun at all.

Another great thing:

gofmt - Go has no style guide, just this tool!

Committed code ends up looking cleaner and you don't have to adapt to other's wacky standards. No more tabs vs spaces arguments or where to place that brace... brilliant.

I'm still of the opinion go messed up the error handling badly. As a simple example note how every tutorial doesn't bother looking for the error return of println calls and hence would silently ignore errors.

IMHO the ideal solution is that if you make no effort to look at the error return of a function, it is automatically returned to your parent. This is somewhat analogous to exceptions, but they require a lot more syntax. (Yes I know about panic/recover.)

"Oh, and there isn't any pointer math, so you won't screw yourself with it."

It has been said before and I'll say it again here, but because you can mess stuff up because you don't know what your doing is a terrible reason to not have something in a language (or even a program).

I've become aware of Go just a few months go, but I already like it so much that I'm planning to make my next/current project in it, after using C++ exclusively the last 8+ years.

It has a lot of good things going for it, as a modern language should, but IMO that only makes it a viable alternative.

What really pushes it over onto the "I wanna use it" side is how easy and natural it makes concurrent programming. See e.g. vimeo.com/53221560

It's interesting how many people post about moving to Go from an interpreted or VM language background. The original presentation video pitched it as a C++ replacement, but that is clearly not the whole story. This author does not seem to have much experience in native development. I wonder if the Go designers predicted how many people they'd convert from python/ruby/java.

Simple C Interface

By using build directives you can integrade with C libraries really easily.

And its a bunch of magic. I thought these people were serious about having a language for "systems programming".

What good is it if it can't properly interface with the systems programming language that people actually use, C?

It seems they wanted to add "C interop", but didn't understand what that means.. at all. You give it a header with function prototypes, because thats apparently the only way to tell it "I want to call this native function", and you get... undefined references for the native functions? What the hell is it even trying to do? You don't have source and you don't have linker stubs for a lot of the libraries you want to interop with.

It's a complete non-starter. It's interop for awesome magic demos.

IANAL: Why isn't patent exhaustion a solid defense to Monsanto's suits?

The anti-GMO documentaries I've seen have covered the "their seed blew into my field" and "I bought seed and signed a contract to only sew it one season then breached it" type lawsuits, but not this --

He's buying seed, from a third party, without signing any agreement with Monsanto. That seed isn't even necessarily Monsanto's product, but from plants that descended from those seeds. It may contain the patented genes, but those genes only got there from the original authorized sale of seed to whoever owned the elevator.

The exhaustion doctrine says that a patent holder's rights end at the point of an authorized sale. Once Apple sells you an iPad, you can do whatever you want with that iPad, including selling it to someone else, and aren't infringing the underlying patents the product implements.

So, why can Monsanto claim damages here?

I think Assange's interview at TED was a much more concrete discussion of Wikileaks and its role in politics -- there were real examples in the interview:

http://www.ted.com/talks/julian_assange_why_the_world_needs_...

I feel like Maher hinted at a lot of different things, but never actually went in-depth. The discussion was very vague. I would have loved to learn about more cases where Wikileaks was able to provide information that was able to influence a government's actions.

Summary... nothing really new.

Some fairly loaded leading questions and the classic false accusation of charges with regards to Swedish request for extradition (though perhaps in the knowledge that Julian would have an opportunity to correct it).

Julian made an appeal to people from within the Whitehouse with access to secret laws and procedures affecting citizen's rights to come forward and share them with the public via Wikileaks.

Bill makes smart-arse crack about sending in Ben Affleck "like we did in Iran".

This is hilarious - though I wish they had more of an artificial delay between the hops to keep the suspense. If you're curious how you might implement this without actually needing a whole bunch of different hosts with routes between them, see this tool by Moxie Marlinspike:

http://www.thoughtcrime.org/software/fakeroute/

You still need a big block of IP addresses though since you want the reverse DNS lookup for each IP address to return a different line from the scroll. Definitely a waste of IPv4 addresses; someone some do a IPv6 implementation ;-)

Edit: I just noticed http://beaglenetworks.net/ at the bottom of the traceroute - this was implemented by carefully setting up routing tables and VRFs on a Cisco router. fakeroute seems easier but not a bad way to keep busy during a blizzard.

Secret weapon is the perfect phrase to describe Kirsty. She handles everything to do with money and investors at YC, and the situations she has to unravel, dealing with early stage startups, are often appallingly complicated. Considering the number of startups we fund, I bet there is no one in the world who understands more about the intricacies of early stage startup finances.

A few months back I was sort of afraid to write to PG/YC directly. We were putting in our first submission on HN (our web app) when we found that the domain name we held was somehow in HN's blocked-list.

After some hesitation I wrote a short mail (with etiquette of writing to busy people) on YC's email address and within seconds Kirsty replied to me. It made me feel good when she told us that "if it is blocked, avoid posting it again on HN. Have patience, PG will unblock it in a few minutes."

After sometime I received an email nod from PG too. From that point I just fell in love with Hacker News.

I like Kirsty's quote: "I was shocked at the amount of trust that was being placed on me at first." It reminds me of how when I started at my current job, our head of engineering gave me logins and passwords for every piece of software we had. In my first meeting with her and my manager, my manager says, "Woah, I don't even have access to half this stuff." It was really inspiring to know they trusted me enough with the keys to the kingdom, and it made life so much easier than the previous companies where I had to fill out a form for access to just about anything. More companies could do well to place more trust in their employees like this.

Nathoo says that of the current class of 47 startups at Y Combinator, only one company's incorporation documents were problem-free when joining the program."

While the title-compounding effect did strike me as comical, this did force me to reflect a bit on our own worship of pedigree. Anyone who's spent any time on Angel List has undoubtedly been treated to "founders from stanford & MIT", "started by Berkeley students", "MBA from Chicago", etc.

I've basically just finished this process, described in the post, over the last few months.

Experienced with PHP, Ruby, and SQL, but zero JavaScript.

(1) - Tried to read Crockford's "The Good Parts", but was completely confused.

(2) - Read "Professional JavaScript for Web Developers, 3rd Edition", cover-to-cover, making sure I used and understood each point before continuing.

http://www.wrox.com/WileyCDA/WroxTitle/Professional-JavaScri...

(3) - Went back to "JavaScript - The Good Parts" and realized that "Professional JavaScript for Web Developers, 3rd Edition" had already covered everything in it, but explained so much more clearly.

(4) - Now I'm trying intermediate to advanced JavaScript books ("Secrets of the JavaScript Ninja", for example), and finding that "Professional JavaScript for Web Developers, 3rd Edition" covered most of their lessons, too.

The point?

If you want to learn JavaScript, (or recommend one book to someone else who wants to), whether you're an experienced programmer or not, get "Professional JavaScript for Web Developers, 3rd Edition". It's thorough and great.

Direct link to the publisher where you can get the DRM-free PDF:

Javascript must be one of those few languages where you cannot learn from bits and pieces. I learned python, C, shell etc from bits and pieces, but I actually learned javascript the way OP describes.

This is actually quite puzzling and I've been thinking for a bit. Why is it one is unable to learn from the instant utility of javascript the same way one learns instant utility in python, ruby or even C?

I've tried to teach my friends and acquaintances that are interested in programming, but my curriculums never work out. It seems that the bigger problem for the guys I'm talking about (high school and college age) is self-motivation and drive that they are unfamiliar with from their academic careers. Anybody motivated enough could learn programming because all of the necessary resources and training is freely available. The OP's curriculum looks like a fantastic way to get into JavaScript for somebody motivated. The bigger question then is, how do you motivate somebody that likes the idea of programming to also happily accept the hard work involved?

It's arguably not that interesting to consider oscillation between these two things because basically it's the same problem under two names. There's a pretty large amount of fungibility among a 90s .edu home page, a geocities home page, a Wordpress instance, highly-customized Myspace or Tumblr.

I don't meant to suggest nothing has changed. It's significant that the required technical knowledge has reduced and extraneous degrees of freedom have been removed and there are simple ways of discovering other users and their posts. It has democratized the personal page and mainstreamed something which used to be for arch-nerds. But everyone has done these things.

Most of the innovative activity of this Facebook/Twitter generation of sites seems to be in playing with different ways of locking people in (sorry: I mean being 'sticky'), getting more data and exploiting it better. Other than that, the competition seems to be mostly about marketing and network effect. These seem like continuous efforts not subject to much permanent advantage.
Does anyone ever just win on this basis? Do we really imagine that it will still be Facebook and Twitter in 30 years (like Coke and McDonalds 30 years ago)?

I'm not very convinced by the analysis presented in this post, but it seems fairly clear to me that at some point in the (near?) future people will start to think of social web services as more of a commodity rather than some big shiny gold rush that we all have to be part of.

Maybe then we can stop throwing piles of money at people who want to build walled gardens and go back in the direction of people hosting their own content for others to peruse.

(Yes, I'm predicting the failure of Google+ as well as Facebook and all the other me-too services like mass photoblogging services and all that other crap.)

We've spent too much time and effort writing code to help people push their content into companies that will claim the right to own it. Let's make tools that help people express themselves in ways that benefit everyone and that ensure creators retain ownership of the work they create.

This is a pretty weak pitch. Basically the person takes two sets of stats and creates an argument that isn't necessarily grounded in reality. The stats don't correlate, nor do they consider what end users are going to do.

Now, is there room for blogs to make a comeback? Yes. There are publishing networks big (Medium) and small (see all the Markdown+Dropbox blog platforms) that are gunning for WordPress and Tumblr right now, which suggests that we're going to find new ways to encourage movement on the medium-form writing style.

And here's the other thing: While blogs are more likely to influence a purchase than Facebook, any good marketer has presence on Facebook, YouTube, LinkedIn, Twitter and blogs. That one percent difference is nullified if they have their hands in multiple pockets with multiple approaches.

A lot of what marketing clients look for is a top-down approach which takes into account each of the tools at our disposal and finds ways to make each of them work together. You can't treat one as more important than the other, though Facebook is certainly getting the lion's share of the attention right now. If anything, the second graphic in this post shows the value of a more holistic approach, not one that relies largely on one platform over another. If you're really doing it right, you're leveraging Twitter to lead someone to a blog post, getting them to watch your YouTube video, and drawing a like on a Facebook page all in a single visit … and the triangulation of these elements eventually leads to a sale and/or a growth of brand awareness.

This effect exists due to the very nature of blogs, which the author seems to fail to take into account.

In blogging you're talking about a very large number of individuals, most of whom are not likely going to be good at ad sales / management / placement. The blogging ecosystem is inherently chaotic, it'd be like herding cats trying to get blog based advertising up to the effectiveness of a singular organization of massive scale like Facebook.

Then you have a huge portion of the blogging world that is made up of corporate blogs, non-profit blogs, and so on and many of those simply will never have any interest in ad monetization.

To correct the imbalance would require a very large and efficient ad machine at the core of the blogging world, with the ability to determine placement and ad matching for every blog - that doesn't exist and never will. Slapping AdSense on a blog won't cut it (not to mention most blogs don't run any serious advertising and never will).

The analysis ignores that as a company, you spend budget on buying Facebook ads. That's in addition to the money you spend directly maintaining your FB and blog. The fact that a larger percentage of budgets are going to FB just tells you that's where companies spend money to attract new eyeballs to both their FB page and their blog - most of the companies I follow on FB primarily post links to their blogs.

A blog is a great way to meet people with similar interests, which is the purported reason for social networks. Nothing wrong with people using social networks but for people who can manage their own site, that just seems like a better way to invest energy creating content.

>I think in 2013 and beyond we will see social media spending go up, but we will also see a big shift from Facebook and Twitter back towards blogs as influencers

I'm not convinced that blogs ever stopped being "influencers," especially given how much Google traffic goes to blogs. I suspect that whatever metrics dendory.net and others are using, however, have understated the impact of blogs and probably have for a long time.

I do think we've seen blogs shift: people with long-form aspirations write them. People who just want to post links and one-liners that are only likely to be of interest to a small circle of people use Facebook and so on.

Certainly I've spent a LOT more time writing blog posts than I've spent on Facebook, but I'm also anomalous in this respect.

EDIT: I should've just written, "I think companies are catching up to what most of us already know about the differences in purpose in both readership and writership between blogs and Facebook."

cwharland 6 hours ago 1 reply      
It's not at all clear that advertising on a blog will increase sales just because blogs are influential in the buying process. If I read a blog post that is an honest, unbiased review of a product it will likely contribute greatly to a decision to buy that product. But the power of the blog's suggestion had little to do with the fact that it was a blog and a lot to do with the fact that they were not paid to review.

If I'm reviewing simply to advertise then I lose a great deal of credibility and influence as far as the consumer is concerned. Advertising on blogs will simply shift them from the blog category to the retail or brand site category which may cost them influence.

This is the closest thing I've seen to the 'star complex'. I went to school in LA and met a number of folks actors and actresses. When they are early in their career they can mingle with people "outside" the business, as they become more well known this gets harder.

When people have only seen you in one role, and you were "playing" that role, they think they know you (if you were good at it anyway). But if that isn't you, especially if it is strongly not you, then you find the "wrong" kind of people want to be friends. Wrong here is relative, its people who want to friends with the person whose role you are playing, except that is not you, and they may not want to be friends with you the person you actually are. It was a running gag with Ginger on Gilligan's Island.

One of the things I like about engineering and general nerditude is that it has largely been immune to these sorts of forces. One of the most depressing parts of the dot com bubble/boom was how 'hollywood' everything got, with people playing the part of quirky ninja rockstar techie.

That made me uncomfortable because it exposed that what I valued, and how I comported myself, could be put put on like a cloak by someone who was skilled a mimicking the mannerisms and the habits of engineers I respected. And that made me sit back reflexively and ask myself how much of what I said, did, and felt was me, and how much was what I played as a "silicon valley engineer" ?

So... how much of the NES does this emulate? As I understand it, it's pretty easy to get a basic 6502 core and a scanline renderer together enough to handle, say, Super Mario Bros. but if you support all the timing corner-cases and memory-map chips and such, it gets to be pretty frustratingly complicated.

EDIT: I should have looked more closely; looking into 'mapper.rs' reveals that it currently supports only the vanilla NES memory-map.

I think it's neat that this doesn't used any managed pointers and avoids the Garbage collector. The fact that you can simply grep a codebase for '@' to find cases of managed memory is great in my opinion. I've been learning the Rust syntax a bit but am currently stuck trying to find a problem to solve with it that doesn't require me writing a bunch of libs from scratch or writing C interfaces. The Std/Core libraries are still rather lacking compared to say, the Go std lib.

I'm sure that will change, but for now it seems unfortunate. For example, there's an HTTP lib as part of Servo but according to some people in the IRC, it's not even very good.

I'm reading this like 'the singularity is upon us'. We aren't there yet, but articles like this are very good (even if they are slightly non-realistic at the moment) to throw a dart at where we, as a civilization, could end up. We have lost the ability to question where we'll go, because we move faster than our feet can take us. We are sliding down a snowy hill, holding on for dear life, hoping there's a nice landing at the bottom that won't end with us crashing. We've lost control of the sled, but it still moves forward because there's nothing to stop it.

I have an anecdote from Germany, and one from Uganda that kind of flow with the idea of 'if you want to, you can, but why?'. We are talented creators, we can make awesome things. Almost anything you think of now a days can be created (and likely has). Some of these things shouldn't have been created, and if every time we want something we ask "but why?", I think it help us to realize where we're going. These are anecdotes from friends, I have no idea of their truth, but they're interesting nonetheless (if it's wrong, consider it fiction).

In Germany, the buses run on time. When the buses are just a couple minutes late, people start getting mad. Ultra efficiency, where everything is perfectly meshed together like the gears on a Swiss watch. The timing is perfect, and it lets life progress with a minimum of fuss and extraneous endeavors. Get in, get out, get on your way.

In Uganda, when you invite someone over to your place to get together, you can set up a time. They'll get there, but they might be eight hours late from the time you set up. They might start walking, and talk to everyone they see along the way. They'll get the scoop on everyone's life, and share the human experiences that are happening around them. This lateness would sound like insanity to most people, but once you realize that everyone's clock is adjusted to the lag time of getting somewhere, it's not a big deal.

Now we, as humans, can create the most efficient complex world that we want to. But why? I think we have collectively lost a lot of modesty as our world has been progressing. We love to play games, we always need a challenge to solve. There's challenges all around us, and the money from solving the challenges is ripe for the taking. It doesn't matter what you do to get there - if you get the money, you get the prize and you won. The ripple effects are what does us in, and the ripples are the unexpected or unintentional differences that were created in our society after adopting the solution to the challenge. Some examples of technology with ripple effects are things like lead paint, leaded gasoline, clear cutting forests, asbestos insulation, etc. We might have been able to predict these things would be bad before we started if we thought a little longer. I'm sure a lot of people knew it would be bad, but it was the easier one that solved a 'problem' that we had. We're young as a civilization, and we are going to make mistakes. The mistakes we should not make though are ones that could have been prevented with a little bit of thought before jumping in head over heels (drunk driving for instance, if you don't do it, you will likely live a bit longer). It takes self restraint (from a person) and conditioning/education (from society) to reduce the number of drunk drivers. The trouble is that we have no restraint with advancing technology, and our society hasn't had the change to find the differences that are created when we advance it.

We're like dogs trying to resist the urge to pounce on a piece of meat. We simply can not let something pass us by. If there's a forest to ravage, or an ocean to destroy, we will do it, and we'll do it well. Try this - the next time you think of something cool to make, DON'T MAKE IT. Think about it, see it in your head, but resist the urge to make it. It's very, very challenging.

It's easy to know what you've lost after you've lost something, it's hard to predict what you're going to lose. When we do something, we have to change society, and we lose parts of society that we had before. Sometimes the changes are good, sometimes they're bad, but before changing it we should think about what we're doing.

I fail to see in this article where the author backs up this claim:

> automation is replacing both brawn and brains and is leaving little for humans to do that computers can't.

It will be a very long time until computer automation can replaced knowledge workers.

At the moment, technology is making knowledge workers more effective and efficient. It's not even close to replacing them.

Let's not try to solve problems we don't yet have.

The claim of replacing physical labor is legitimate. But if you look at china or the US, the amount of kids getting educated in universities, whose parents worked as labours has exploded.

The key now is getting the kids to have useful skillsets to the industries that need them. Which is something universities have been failing to promote accurately compared to the demands of the market.

It seems that similar concerns have been voiced with every advance in technology that replaced works with machines. The argument generally assumes that the amount of "work" needed will remain relatively the same. So, if society today requires 100 works to make one widget, and we can make the same widget with 1 worker and assorted machines, then 99 works will be left unemployed.

In reality, what seems to happen is that because the products of that work become cheaper, society starts to consume a lot more. In the end, something like 80 works end up supervising the machines, while 9 works maintain them and the other work is designing the machines.

I can't foresee what will happen if all basic service jobs are automated, but then again it will not happen overnight. The biggest question in my mind, is how well will the society repare the future generations with the skills they will need to remain relevant. Education is everything... and it will remain everything. (Not formal education mind you, but more so knowledge/training.)

I am basing my startup mostly on this discussion / meme - so I am happy to see it on HN. However the stage I think has been missed by the article (in the rush to say 2120!) is a transition away from commuting and into massive remote working, probably in the next ten years. The costs of commuting and office space is enormous compared to it's benefits for most jobs so we shall see a sea change in how jobs are measured and managed, leading to the path to remote working being freed up.

Oddly in software continuous integration / delivery is that sea change. In marketing? It's AB testing. In everything else? We shall see.

I mostly worry about this scenario of not enough work for everyone because too many people in my country (USA) will probably be unwilling to support a universal living wage.

A social safety net improves the lives of everyone because of lower crime and a generally more civil society.

The trick will be to provide life long educational and vocational resources. Hopefully almost everyone would want to produce extra value for society and improve their own material life style. There would still be room for very capable people to be "rich" and generally rewarded for skills and hard work.

So, a pure meritocracy with rewards layered on top of a minimal universal ling wage sounds good to me.

The article was very interesting, as it highlights the specific bipolarity of having a startup, but when I actually visited your site I was confused.

I like the idea of your app. I really do. But I had no idea what the hell Curvio does from the splash page,

The first thing I read when I hit the landing page is:
"New shows are being added all the time, Sign Up to be emailed when they are!" -- When I read that I thought this website was some sort of a tv guide. It emails me whenever a new show is made or released on television.

The second line wasn't much better:
"Find great looks from your favorite TV shows:"
I was confused from the first line, so I didn't understand the context of 'looks'

It wasn't until I clicked on a show and saw that you were indexing specific outfits from specific episodes that I truly understood what you guys were doing. Otherwise, the home page didn't tell me anything.

Just my two cents.

Organic traffic drops 50% - what number of organic visits are you getting daily? If its low (in the hundreds) a 50% drop could mean nothing at all, just daily variance. Our organic traffic fluctuates up to 20% during the week (~7k organic per day) and it's very cyclical as well (we expect the same pattern the following week).

I don't think it's worth stressing too much about an odd data point, always best to look retrospectively at the bigger picture!

What no one seems to think about is the potential health consequences of this application of nanotech.

This is basically something made with particles that are much smaller than your cells. The material can probably get into your body by osmosis alone. Will the materials affect your body? Cause cancer? Get stuck in your lungs? Do something else that we don't know? There has been very little research on this area, and the little research that has been done is worrying. Putting this in consumer products is a very large and uncontrolled experiment.

We should be careful of starting to use materials like these with no further study or testing. There is a risk we might end up looking like the guys who brushed their teeth with radium or used a portable x-ray video machine to examine their kids' feet at the shoe store.

Well this concept is based on superhydrophobicity. I do not know the working of this coating particularly, but it seems to be superhydrophobic. A superhydrophobic surface(SHS) is one where water has very high mobility i.e. an extremely water repelling surface. Is is due to a surface having low surface energy and a textured topography. They hold very high commercialization potential. Lotus leaf is one natural occuring example of this phenomenon. The research into this field started extensively in 1997. SHS can be employed in variety of applications theoretically i.e. cars, windshields, toilets, ketchup bottles, kettles, phones, power lines, preventing ice accumulation, on boat hulls, on shoes in rain, fabrics, solar cells, around sinks, shower curtains... the potential is unlimited. Many researchers are working on making it possible, and they are very good ones too.

So after you have been primed about the subject, what is preventing their wide spread usage? Durability. Not a single one of them is able to sustain mechanical duress. And one of the most widely used chemical is Teflon, which is expensive. Hence, reapplication is not possible time and again. Many researchers are working on it, but a solution remains elusive until now. These sprays are nice such that they open the field, but much more still needs to be done in this field, since these sprays have been in market for at least 5 years now.

No, that's just the abstract. Claim 1, for example, reads as follows:

    1. A computer-implemented method for providing recurring delivery of
products, the method comprising performing instructions under the control of
a computer system for:

receiving at the computer system a designation of a delivery slot and
a recurring delivery list comprising one or more list items, each of
the one or more list items identifying a product, a quantity to deliver,
and a frequency of delivery;

periodically generating, by the computer system, an order having a date
and time for delivery based on a next occurrence of the delivery slot, the
order being generated in advance of the date and time for delivery such that
the order has a period of time of pendency prior to the delivery;

creating, by the computer system, one or more order items for the order
based on a last delivery date and the frequency of delivery of each
list item in the recurring delivery list;

receiving at the computer system a change made to a first list item of the
recurring delivery list during the period of time of pendency of the order;

in response to receiving the change, determining, by the computer system,
whether the order includes an order item corresponding to the first list item;

in response to determining that the order includes an order item corresponding
to the first list item, modifying, by the computer system, the order
item corresponding to the first list item based on the change made to the
first list item of the recurring delivery list; and

providing, by the computer system, the order to an order fulfillment system
capable of causing the one or more order items to be delivered
substantially on the date and time for delivery.

Now, I consider myself a creative person. But I would have a hell of a time trying to read that claim on a fucking milkman.

There is abundant prior art on this one.

E.g., one casualty of the dot-com bubble was Streamline, an online grocery delivery company. They called their version of the invention Don't Run Out. Fast Company raved about it in this article dated July 31, 1998:

    What happens when customers depend on you - and you deliver?
They decide to depend on you even more. One of Streamline's most
popular services is called Don't Run Out. Families identify
their must-have items - milk, toilet paper, diapers, pet food -
and authorize the company to replenish their stock of each item
automatically. Today almost every Streamline household uses
Don't Run Out. The average household has standing orders for
more than 10 items. "It's extraordinary," says [Gina] Wilcox. "The
consumer makes a purchase decision once, and we fill the order
throughout the year. It redefines brand loyalty. It redefines
marketing."

Also have you looked at dropwizard (http://dropwizard.codahale.com/) it's really simple to use. Would like to know your thoughts on that and also how your framework compares to theirs.

At the end of the day, though, I'd be happy working in a Java framework wherein the experience didn't feel like I was forcing myself to write Java code. It's just such an uphill battle when the dev experience of (rails/node/django/webapp/web.py) is radically different from just about everything Java has to offer. The lack of a sane package manager, for one, is a major downer.

One of the recurring problems with docs for java projects is that they spend a lot of time talking about how the framework works. The great thing about those sinatra docs is that they're focused on telling you how to do things. As a user of the framework this is great as generally I'm trying to build something and just want to know how to do it as quickly as possible. Having great docs means that more people are going to use your project so it's an area where your efforts will really pay off. It looks like a great project and I look forward to using it.

I come to think that the main issue with doing web with Java is the inability to do auto reload. There is somewhat way to do this in case of using remote debugging, but it works only on method level. And even when this works, most of the Java tooling actually sits in the way of this. For instance web servers/applications, frameworks and build systems.

However having the framework in Java and actual web app logic in some dynamic language works very smoothly - I've done something similar with JS (Rhino) where the server actually takes care of auto reload and module system. Not really finished but: http://code.google.com/p/sodejs-java wow maybe I should move it to github finally).

Having been educated only as an undergrad at a college ranked ~100, I have a question for those who've experienced a course like this at MIT or a similar institution. When I was reading the first lab's description I thought "man, that'd be tough to put out in a week, but it's doable." I saw that it appears to be a multi-week lab for graduate students and wanted to find out if this is normal difficulty for a course? Is there more homework outside of labs that's missing, or crazy quizes/tests that deal with much more theory or proof style work? I just recall my undergrad courses having those extra items, but in large part being the case that if you made all your labs pass all the test cases you could get an A in the course. Does this hold true even at the elite schools or is there much more hidden below the surface here?

Apparently he felt Go was better for that than C++, though he didn't spend any time comparing the two.

FreeBSD may or may not be faster than Linux for gaming.. but it does not matter -- freebsd is NOT a desktop OS. I've been using it for 15 years, 14 of those years on my desktop. Buggy desktops, no binary updates for ports, etc, etc. The entire thing is an exercise in frustration.

A decade ago, you could use FreeBSD on a desktop and it would be more or less similar to a Linux desktop. But Linux has more resources, and has invested more than FreeBSD into the desktop.. and FreeBSD has focused their limited resources on the server.

Today it's not even a contest. FreeBSD, if you like it, goes on a server. Linux on the desktop.

Need a workstation to develop the software for your FreeBSD server? - use Linux for the workstation and compile it on a FreeBSD build server. (I'm not kidding.. I actually use this setup for work...)

3D printing and the future of retail daltoncaldwell.com

Interesting notions, but a few counterpoints:

+ 3-D printers aren't economical ‚Ä" Something like a drywall anchor takes a couple seconds to produce in a traditional injection molding process. It would likely take 15-30 minutes using an FDM 3-D printing process and even longer using a higher resolution SLA system.

+ Print-on-Demand hasn't taken off on books, why will it with physical goods? Print-on-Demand technology has been available for the better part of a decade, but Barnes & Noble and Borders never saw an opportunity to implement it. Again, this comes down to speed. For undifferentiated products, it will always be faster to mass produce.

+ Even taking the argument at face value that 3-D printing will help digitize inventory and create the same pressures that digital media did, I think more efficient mass production, rather than 3-D printing will be the likely case. Zara can produce limited runs of high fashion clothing and get them into malls all across the US in 2 weeks. Protomold makes low cost, small run injection molding accessible. We'll likely see more of this rather than fleets of MakerBots.

+ The problem with retail is the cost model of keeping store fronts open, not the way the products in it are produced. Even if we assumed there would be big box stores full of 3-D printers, they are still slow and do not have a Moore's Law like effect that will change that any time soon. If I ordered something at one of these 3-D printer stores, I'd have to wait hours to get my products. Why not just go straight to ecommerce at that point.

+ Producing Atoms is REALLY, REALLY hard. There are tens of thousands of different plastic formulations. Different additives, secondary processes, and assembly steps that go into high fit and finish products. Even the best 3-D printers can only handle a few materials ‚Ä" at most. There is no way to produce something like a pair of "Beats by Dre" headphones or a similarly complex electromechanical device using those systems. The simple things that can be produced would be more economical being mass produced and warehoused in a low cost location and shipped to customers rather than printed on demand.

Think about the difference in quality between a printer at home and one of the nice photosystems at a pro printer. Even then when dealing with paper stock and 4 colors of ink the difference is striking. Now increase the difficulty by several orders of magnitude.

3-D printers will have a huge impact, but more in the way open source programming languages did. They lower the bar to entry and let more people get involved with manufacturing, but will be limited utility tools, not everyday items ‚Ä" at least in the way this post posits.

The main take-away I have from this blog post, is that the term "3D printing" is increasingly used to mean "automated manufacturing", even by people who are sophisticated enough to publish on Svbtle.

There aren't many products out there that can be produced by 3D printing alone. You can, however, get to the point the author suggests by applying "high automation" (integrating multiple automated fabrication methods into an automated manufacturing system).

Nevertheless, can at least those of us in the know insist on using the term "3D printing" precisely, i.e. only for additive manufacturing processes? That would be splendid, I think.

I'm with replicatorblog below. The article is sensationalist. And psadri is correct in that "on-demand manufacturing" is the real revolution.

From the article:

Q: "What percentage of the square footage of Home Depot is devoted to items that could cheaply and easily be 3D printed?"

A: Less than 1%

Here's some thoughts on the real issues in the space:

Retailers aren't just financially leveraged, i.e. by debt, but also operationally leveraged, too.

A "business that has a higher proportion of fixed costs and a lower proportion of variable costs is said to have used more operating leverage" [1]. Given the low sales/fixed costs per square inch most brick-and-mortar retailers incur they would be vulnerable without a cent of debt.

Note that the prevalence of home inkjet printers hasn't bankrupted professional printers, just forced them to specialise.

Oven knobs, fine. But there are so many things that can't be machine printed; they require the assembly of components made of very different materials.

Take "sporting goods" mentioned in the article. Tennis racquet: supposing you could print a frame that was strong enough (dubious) with an acceptable grip feel (very dubious), you can't print the strings. They need to be assembled into the frame. Baseball, baseball mitt, basketball, etc.

Somebody here mentioned you can't print headphones, anything electromechanical. I'll add, anything with a circuit board in it, anything with an LCD or OLED screen on it; anything with a motor in it; anything with a heating element (coffee maker, hot pad). Anything with springs or hinged or rotating parts (many toys).

Retail won't go away. Shopping is something people like to do to some extent. Also, as someone mentioned, Starbucks thrives despite you could make your coffee at home. Even people who can cook well, go to restaurants... etc.

An interesting thought: coffee is probably much easier to make than arbitrary 3D objects made of various materials. Yet coffee makers have not become as ubiquitous as CD burners.

What I want to know is why.

see also that on-demand book printer that prints double-sided , cuts, and binds the book with cover. its on-site automated assembly in general. IKEA's strategy is a bit like this too. its like what if IKEA had a robot that manufactured the furniture at retail location? what if the lego block catalog was available from a kiosk in the toy aisle and you could print individual parts by tapping?

The internet is already doing brick and mortar stores in.

Perhaps on-demand manufacturing (for example, but not necessarily, 3D printing) will also contribute.

Doesn't matter if it's signed code. I still turned off Secure Boot on my T430. It is rare that I have ever gotten malware, much less any that execute code at boot. Boot-sector virii died off in the late 90s.

Make no doubt about it; this is just another monopolistic implementation of restrictive technology by Microsoft.

I'm not 100% sure what this means. I remember hearing a lot of rabble rabble a few months back about Microsoft placing some roadblocks on hardware that would make it more difficult to install Linux on machines.

Does this mean this is now a non-issue?

This idea of petitioning Oracle would be comical were it not so pathetic. In case it needs to be said, Oracle is a corporate sociopath -- it cannot empathize. One could have a petition with quite literally 6.9 billion signatures on it; it would change nothing. As I've cautioned before[1], do not fall into the trap of anthropomorphizing Larry Ellison...

I'm not signing that petition, because fuck Oracle, and fuck Java in the browser. We don't need it anymore. I hope they keep bloating it until people simply refuse to install it, and even corporate IT departments start saying "what the fuck?" and start porting their software to something else. JavaScript, CSS3, Canvas, even SVG does everything the Java plugin did, but better. Way better.

EDIT: Wow. Didn't realize I felt that strongly until I wrote this. But client-side Java, which I spent many years programming, is a tragedy of epic proportions, and my anger hides a real sadness.

6000 people? The more appropriate subject here would be "Most users don't care about Java bloatware".

Let Oracle bundle their bloated adware. Don't provide them a free service by telling them how stupid and self-destructive this practice is; if they're too dumb to work out that it isn't in their long-term interests, they deserve the consequences.

Publicly traded corporations are all the same; they're all equally obnoxious, a-moral, and hostile to customers when it suits their perceived interests. Oracle's Java adware is just a tiny little symptom of this; the actual problem is systemic to public corporations.

This kind of obnoxious user-hostility is what made me abandon closed source software for personal use. Additionally, my company (a private company) doesn't use any closed-source software in our systems, and never will. For us, open source software is better, more flexible, more supportable, and the nail in the coffin is that there simply aren't any vendors that can be trusted by a small organisation such as us.

Oracle don't care about little people signing a petition anyway. If one of their large corporate customers told them directly that this was unacceptable, they would stop it in a minute.

Having setup a new computer and installed Java on it recently, I found the inclusion of this bloatware very tacky. It's also frustrating because in the past, I have told family members to "just answer yes" to Java update prompts. I'll probably just remove it from their computers now, if given the chance.
