Microsoft killed my Pappy hanselman.com

This is a shockingly honest and open assessment of Microsoft's PR from someone who actually works at the company. I think the underlying notion is spot-on, and -- as someone who doesn't bear any particular ill will towards Microsoft besides the travesty that is Excel for Mac -- its interesting to see the seeds being sown of irrational Google hatred.

> Is Microsoft circa 2014 worse than Google, Apple, or Facebook? We're not nearly as organized as we'd need to be to be as evil as you might think we are.

Microsoft is not any worse than the other companies. They are all at the same terrible level.

But Microsoft became a bit better over the last years, I would say.

Every time I have to suffer through the archaic UI of Word and enjoy late 1990s performance in the mid 2010s, I am reminded that my Pappy is still dead, even though MS could have made amends. They haven't. And in addition to my Pappy there's a whole other cast of characters that are dead, and they've saddled the entire world with mediocre-to-bad computing experiences. No amends for that either. Perhaps can't make amends, because they are themselves too stuck in the past, unwilling to fix their ways or legacy programs.

The world of computing could have been and would be today a better place if they hadn't dominated through business practices, but instead dominated with products.

When you stop shaking down your competitors with software patents, let me know. Until then, your talk about openness is just talk. Extracting settlements from android OEMs over FAT patents is contrary to all the values you've mentioned in this post.

Even if I concede all that, in the meantime, we've had the "Secure boot" fiasco and some other things I don't remember distinctly. I just remember constantly trying to fight the instinct to hate, to give MS the benefit of the doubt, but I just can't do it.

When discussing past wrongs of an institution, the question to ask is not "how long ago did they do it?" but "has the institution changed since?". In Microsoft's case, the answer seems to me to be "not enough".

I can't speak for anyone else, but as a Web developer, I hate Microsoft because of their current and recent handling of Internet Explorer - specifically that it doesn't auto-update.

I love my job, but in my job, Internet Explorer 8-9 is pain. It's why we can't have nice things. I checked out a Windows Phone in a store once, and thought it was pretty sweet until I saw the IE logo and physically recoiled. There was no way I was going to own something where I'd have to hit that logo every day to browse the Internet.

That's not ancient history, that's present-day reality.

This was a great point:

    That's 20 years ago.  And for bundling a browser    in the operating system that couldn't be uninstalled    or easily replaced? Sure, no operating systems do that    in 2014. I wonder if I can swap out Chrome from Chrome    OS or Mobile Safari in iOS. Point is, it's common now.
I lived through this time "hating" Microsoft for some of the stuff it was doing then, and it's probably well past time to bury those hatchets.

But they still do rather icky things: Rockstar Bidco lawsuits and the "Scroogled" campaign come to mind. I'm biased, but they've got to can it with these things (and just innovate) until I'll look at them as a pleasant company.

Past behavior is a great predictor of the future, and winning back trust is both hard and slow. This post would be more believable if MS isn't still exhorting companies with their large patent portfolio.

Maybe Nadella can change the culture but I have my doubts.

Scott, actions are much louder than words.

It's true, Microsoft is quite different, but not different enough.

For entirely pragmatic reasons, I'd rather use Chrome, Linux, Android, Gmail, Google search and Google Docs.

Typescript looks nice, I might use Babylon.js, and I still use Skype from time to time, but I'll still never use Windows, IE, Hotmail, etc...

Im very excited about this. YC is the smartest group of people Ive ever worked with, and I believe that startups are going to be the major driver for innovation and economic growth going forward.

I was thinking this morning about what it was like to start a startup in early 2005 and how much its changed now. PG has done a remarkable amount to improve the startup ecosystem for foundersin fact, its hard to think of anyone who has done more.

(Also, maybe someday soon well make Hacker News work well on mobile :) )

On semi-unrelated note: Can YC-like incubators/accelerators ever become a public company? Lot of people I know would like to invest in startups but have no time, resources or experience to personally do due diligence. It would be great if public could buy shares of these accelerator companies. The amount from their IPOs can truely trigger exponential growth of startups.

Right now most incubators/accelerators are busy playing small investment/big exits model but there is huge untapped area where one need medium to large capital but can expect 2X-5X return with lower risks. I'm not sure if SEC has any rules against incubators/accelerators going public but for next exponential growth it seems essential.

As a past YC founder that sat on the receiving end of some awesome advice from Sam from time to time I think this is a great thing for YC and for future YC founders.

Aside from being a smart, well connected guy Sam has the innate ability to solve complex problems in a well thought out and efficient manner.

I can't wait to watch YC scale like so many of the companies it has funded. It might be the gold standard for this model of financing, but I think they've only just begun.

Glad to have been a part of YC and glad to be a part of the awesome network of Alums. I sold my first company before I graduated college and never got to be an "Alumni" anywhere else, so in some ways I feel like this is watching my Alma Mater make great forward progress, I'm proud to watch it.

This is absolutely fantastic news for YC, their startups and the community as a whole.

pg was a huge influence on me - I've read all of his essays, watched his talks and studied his comments on HN. I've learned so much about startups and making cool things from him and am now in SF hacking away at a startup solely thanks to the inspiration "How to Make Wealth" gave me.

sama, if you'll take a piece of advice from a lowly HN commenter, please be the same to the next generation of founder/hackers. Don't just be really good at accelerating startups. Teach, inspire, and care. You're inheriting a legacy, now build one of your own.

I've never met you in person but from what I've heard, you're just as capable of this as pg was in your own way. Godspeed.

Thanks for trying to do what many of us secretly wished we could do but can't because of time/skill constraints. I will definitely move to NeoVim the second it's packaged (is it yet?), regardless if you've changed anything yet.

I hate the ideas many programmers have about backwards compatibility, that it's more important than development speed and modern concepts. There is nothing holy about Unix era software, chances are it's shit and a lot of it should be thrown out.

Look at SublimeText, it's got 1% of the features of Vim, yet it's converting Vim users left and right, by its sheer usability.

We as developers in the Open Source community should be ashamed people are still using Vim to write LaTeX in Bash running on terminal emulators. (Yes, it gives me shivers just thinking about how much each of those technologies sucks when you think about how good it all could be.)

krick 13 hours ago 11 replies      
I'm not sure how I feel about this. On the one hand I've been thinking on it for quite a long time already, newer shinier Vim is something I secretly wish for. On the other hand I found it quite problematic. The main problem of Vim is Vimscript. So "newer shinier Vim" is Vim with real programming language instead of vimscript. But it's impossible to remove Vimscript: it won't be Vim anymore. It affects not only scripting itself, but also how we interact with it in command mode, not to say about plugins we have already.

And here we have a project. Virtually nothing is done, previous commit was 20 days ago, and the last commit is adding the fundraiser link an hour ago. I mean, the author doesn't seem to be fanatically enthusiastic. And plans are quite generous. Maybe I'm too pessimistic, but I have some bad feeling about that. I'm thinking instead of "Hm, maybe better to write an open-source version of Sublime Text?".

If you can make Vim seamlessly work with a REPL then this would be worth me upgrading (if all my current vim plugins still work).

It's the only reason I use Emacs + Evil + trying to get it to be as close to a Vim clone as possible. You know how cool it is to type ":" instead of M-x?

Finally, someone took this step. I really appreciate his work.

Don't get me wrong. Vim is an awesome editor and it is the only editor I'm using now. I've been using it for decades and still cannot find an editor which can replace it. Sorry, emacs, I tried several times but failed. I know it's my problem but I'm too familiar with vim's short-cuts.

However, I do think we can still do some improvement on vim, especially on its plugin systems. If you wrote plugins for vim, you know what I'm talking about. For example, can you quickly tell me the differences between map nnoremap nnoremap? How to write comment in vimscript?

To me, vimscript seems like a language patched by lots of authors with inconsistent goals. It's not as cohesive as Emacs Lisp. And there are lots of historical reasons why they do that --- I know, it's backward compatibility. But you have to move forward at some time.

With that being said, I do think it is necessary to have an editor which keeps the good parts in vim and improve it by not considering too much about backward compatibility. I'm so glad that someone did it for us.

As someone who uses Vim to write articles and documentation in addition to code, I'd really love to see a richer UI with proper support for features like variable-width fonts.

The more I think about this, the more I like it. I badly want my vim to be multi-threaded and a separate engine, especially one that had a queue based pub/sub type interface could really open up some cool possibilities. At that point if you could give it the ability to use operational transform for the changes it would make remote editing, as well as remote pairing work really well. I know floobits is doing something similar but I would have to think this would make that much easier to pull off.

I applaud your effort but I worry that this step is not far enough to make a better version of vim. However I really think that we can do better and the famous, great editors (vim, emacs, acme, etc.) all have different features that make them great and unique. I prefer vim because of its modal nature which might be the reason why I find it also ergonomically superior (after remapping ESC to jf) - e.g. I don't like it to stretch my fingers.

On the other hand I never really script vim as I find vimscript just terrible. This is far better in emacs as it uses a decent programming language.

The third aspect I think is not well-designed is window/buffer-managment. In my opinion this point could be outsourced or developed in connection with a tiling WM or terminal multiplexer like tmux/screen (this part is best in acme).

A modern approach I thought about (Yet Another Text Editor Syndrome) would be a client-server architecture with a server node storing buffers with context information (filename, cursor, etc.) to which clients can connect. A client node could be on one hand a viewer (terminal or gui based) doing fancy thing like syntax-hightlighting, cursor control, searching and on the other a REPL (in any language) that just has to implement the bridge to a defined message protocol.

I actually had hoped "Neovim" would be a modern reimagining of a modal Texteditor for the modern time, along one of two paths.

Path 1: An html5+javascript based modal editor where buffers are actually DOM trees, enabling both code and other data to be rendered/edited, and also offering much richer visual enhancements. Javascript is already a great way for enabling a rich plugin ecosystem.

Path 2: Modal Textediting suited for mobile devices. For example based on python+kivy, or even C with SDL, it would be aimed to be portable and to extend the modal interface to touch-based gestures and speech recognition. Akin to "verbal vim", entering vim-like commands with touch or voice gestures, text editing on mobile devices like tablets would immediately suck a lot less...

I think a big reason for Vims popularity is how ubiquitous it is. It's installed by default on most *nix operating systems. Even if I'm not privileged on a system, I can still pull down my dotfiles and have my familiar vim editing experience.

If I understand correctly, plugins written for Vim would be compatible with Neovim, but not vice versa?

Someone mentioned about trying to find out if their have ever been any other chat services that have really made a lot of money on it's own, and it sparked memory of an acquisition that didn't happen quite that long ago, Microsoft buying Skype in 2011, and here is a good recent article about it:

http://www.theguardian.com/technology/2013/aug/30/skype-micr...

The bullet point that stands out for me is this:

Problems monetising it: revenues at the time $860m for the year, losses of $7m amounted to just $1.30 per user per year

So, here we have a company, at acquisition, that was making close to the $1 per year per user that WhatsApp is charging. At the end of 2010 skype had 663 million users and was acquired for $8.5 billion. That's $12.82 a user.

Then, as now with WhatsApp, people are questioning whether Microsoft would ever make enough money to justify such a price. Then, as now, people justified the price based on the sort of intangibles (getting rid of a competitor, strengthening the brand, tapping new markets, etc.) the WhatsApp acquisition is being justified with now.

But there is still the big difference that Facebook, with a business in a similar space (obviously still different but they both are chat/communication based), with a similar revenue model per user per year, but only 3 years later purchased it for $42.22 per user. That's almost 4x the price for a similar acquisition 3 years apart.

And people thought Microsoft was crazy for the price they paid for Skype ... it kind of makes you wonder what the hell is going on.

I assume the motivation for pulling this out of the archive is the WhatsApp purchase. However, I don't think this comparison is truly fair. Not only is WhatsApp monthly adding over twice the userbase ICQ had at the time of purchase, but it is also actually collecting revenue from them. WhatsApp is a real company with real monetization strategies.

I still remember back in 2000 when we still had AOL. I was eight or nine and I had my own aol account. You could have a dozen or so sub accounts on the main one. And because it was a "kids account" there were chat rooms for kids. Being the lovely kid that I was, of course I went into one and was like "how the f*ck are you all?"

Well the kid chat rooms were moderated and our entire AOL account was disabled. My mom had to call to have it re-enabled and of course they told her what I had said.

Fun times...

$19 billion and whatsapp has 465 million users, and ICQ was purchased for $287 million had 12 million users at the time. $40 dollars per user vs $24 dollars per user.

Now if the goal were to acquire users. its far more likely that facebook would have a huge overlap in the number of users it has already and those on whatsapp. That means maybe a cost of acquisition at let's completely speculate $100 dollars per user(maybe more). It seems kind of silly. but then you think about their penetration in developing markets and network effects... I don't know I'm not zuck.

BUT on a complete tangent of my comment. I should start an Israeli chat company. they've had some big exits.

Yeah, if only every product they offered either:

a) had comprehensive search capabilities (YouTube, GMail, map, etc)

b) was at least decent integrated with their flagship search (News, YouTube, images, Blogger, heck, Android, etc)

c) was a variant of their flagship search (images, news, sound, etc)

I think it's fair to say that Drive/Docs/Keep and Calendar are fairly independent of Search. Tsk, tsk, for shame.

Google missed the boat because they only hired academics, not hackers.

They didn't need to embrace standards or build APIs, they just had to hire people who knew how to build products that real people outside the valley wanted. Google got lucky with its first product (search), acquired a company to make it a successful business (Adwords), and kept buying companies to try and onboard innovation.

The technology of the last 10 years should have all been open to experimentation by developers without locking users in. There are a lot of developers who believe in this. It's central to the mission of WhatsApp, btw, so if you doubted that it could be lucrative, you should think again.

WhatsApp has changed and extended their XMPP basis such that it is not even remotely interoperable. They are actively battling third-party implementations. Their server is not federated. How exactly are "open", "experimentation" and "without locking users in" central to WhatsApp's mission?

I strongly believe that was the right way to go. I never understood why Google didn't make a big push for standard structured information. They could have published standards for different industries similar to RSS. Everyone would have gotten on board similar to how every blog was pushing a RSS feed. Once the web moved towards structured data it would have been the first big step towards Semantic web.

Imagine writing apps that could do this: "Phone, please book top movie at the box office and dinner for Friday evening and adjust Nest at home accordingly".

First of all twitter's growth is slowing, so its not very apt to compare them to google. And the same thing may start happening to Facebook in a few years (as people are notoriously fickle with social media sites - which depend on mass adoption - not innovation). I think google is doing the right thing - they are sticking to what they know instead of trying to 'build around the web' and become another Microsoft (who tries to make 'their own version of everything' example - Silverlight).

The premise that they missed the boat is wrong. They built a leaky boat because their core competence is in a different field. Google didn't "Miss the boat" they just never studied Nautical Science.

Google is very good at things that are mathematical, predictable, quantifiable, and numeric.

Google fails at things like Natural Language, Art, Social, Music, Video (youtube doesn't count that's just hosting and they bought it already successful, and it still doesn't hardly make any money)

Facebook would "miss the boat on search". Apple will "miss the boat" on social.

The difference is those guys won't go after a boat if they don't have the competency for it.

As it happens, Secure Transport (edit: on OS X) is open source. I just spent the last hour rummaging through source code ... It was later renamed to "libsecurity_ssl" when it landed on iOS. It's been around since OS X launched. They also have a folder with about four dozen regression tests and a test app, not that I've had the chance to inspect either that closely. The tarballs are spread across two folders in the tarballs index: Security (look for multi-MB file sizes) and libsecurity_ssl. The 5-digit numbers appear to be sequential revision IDs, any single-digit numbers seem historical. (E.g. libsecurity_ssl-6 is before libsecurity_ssl-10 rather than after libsecurity_ssl-55471.)

It appears they haven't posted newer source than this. The most recent timestamp I could find was Oct 11, 2013 in 55471, which corresponds to 7.0 and my 10.9 system has the same version number for Security.framework -- same bundle version of 55471 for 10.9.1 aka 13A581. Previous version numbers don't appear to be as well-maintained. I don't expect a newer release to be posted until the next OS X release, as the source was only published under 10.9, not iOS. Additionally, there's no mention of iOS 7 on http://www.opensource.apple.com/

I couldn't easily find the bug without more to go on, because the code is spread across a few components and really, I'm not an expert in TLS. It appears to have been largely unchanged from 2000-2006 or so. TLS 1.2 brought quite a few changes, but it was neat to browse through the lines of "FIXME" and "TODO" comments, as well as various diffs between releases. And neat to see how much code today still goes back to 1999-2001, sometimes all they did was add a 'k' in front of a few variable names or delete the line in the first README saying the server code wasn't tested against Windows ;-)

It sounds like when 10.9.2 is released, or at worst when 10.10 comes along, you'll see a new push of code to the opensource site. We can all diff 55471 against what comes next to see the changes. (If someone's already running 10.9.2 and its unaffected by the bug exhibited via curl, open /System/Library/Frameworks/Security.framework/Versions/Current/Resources/Info.plist and post the Bundle version.)

Odd. Apple updated iOS 7 and iOS 6 but didn't update Secure Transport in iOS 5? I wonder if the bug was introduced between iOS 5 and 6.

Background on Secure Transport:

"At the bottom of the TLS stack on both iOS and Mac OS X is a component known as Secure Transport. Secure Transport maintains a per-process TLS session cache. When you connect via TLS, the cache stores information about the TLS negotiation so that subsequent connections can connect more quickly. The on-the-wire mechanism is described at the link below.

Sounds like a classic Man-in-the-Middle (MITM) attack.

Just a guess, but from the short description I suspect if you have control over DHCP you can get iOS to use your proxy. From there you can use something like mitmproxy (http://mitmproxy.org/) to forge SSL certificates on the fly and intercept and decrypt SSL traffic without any warnings showing up on the iOS device.

I'm not sure why we only consider that this manuscript is either a hoax or a forgotten language. Why can't it be an expression of whimsical fantasy?

When I was 12, as an introvert kid with too much imagination, I started inventing my own language. I would make up words, sometimes based off various other languages, sometime simply based on how they sounded.

It had a couple of different writing systems, one was a slightly modified version of Greek alphabet, another, more complex, was made of dots and small squiggles that were fast to write (I was fascinated with the Arabic writing system at the time and took inspiration from it even though it didn't look anything like that).

I would write pages of nonsense in that writing system, just to see how it would flow or change over time, just to find patterns, just to have fun.

I even invented my own calendar, using the 88 day revolution of Mercury around the Sun as the year.

When I look at the Voynich Manuscript, all I see is the product of a fertile imagination that went a lot farther than my early teenage attempts at building a coherent world for myself.

I believe that these unconvincing attempts at finding meaning elsewhere -or degrading the object by calling it a hoax- are distracting us from the real beauty of this work of love and imagination.

Well, he's trying to recognize the plants and work out backwards from their known names, but there's a lot of assumptions and glossing over involved in this approach.

1) A figure hints at a sunflower, but the idea is refuted based on the supposed location and date of this manuscript (sunflower is native from the American continent).

2) Another figure was recognized as "coriander", that looks nothing like it, but they went with it anyway because the transcript was possible.

It looks like a botanist is more likely to figure out this manuscript than a linguist. The other theory that this manuscript is about plants from the american continent [1] is less flawed in my opinion. It could also explain why it's in an totally unfamiliar script, as it could be a pre-Spanish language, or an attempt from a foreign to codify it.

One of the ironies here is that it's actually much easier for the smartest kids to excel in school if they have a healthy level of disrespect for it.

Intrinsic motivation is the dominant factor. A student that's actually driven by curiosity and a desire to master everything he or she can is tens or hundreds of times more effective than someone acting out of extrinsic motivation -- the carrots and sticks of grades and punishments.

It is so much easier to learn this way that the other kids who are just slogging it out seem to be moving in slow motion. Staying far enough ahead of them to get good grades takes very little effort when you've actually internalized that learning is something you do for fun.

The real trick of course is igniting the desire in the first place. Which has been obvious for at least two millennia:

There's a saying at Harvard Business School... (I didn't attend, so I'm not namedropping!)

The A students become professors. The B students work for the C students.

The academic society forces this focus on high grades across all subjects that is unhealthy.

But what's a student to do? If you can't get into a top school with a couple of Bs, life gets tougher. If you want to major in Computer Science, any school is fine. If you want to major in Philosophy, you had better get into a top 10 school. And once there, you'd had better get top grades because you'll need to go to graduate school.

The problem is even larger than the author suggests. If you're in a large city, to get into the nice high school with the fancy IB program, you might need straight As in junior high. And that junior high school may have competitive admissions.

It's a wonder that any creativity survives!

Amen.

Getting an A- in 9th grade may have been the best thing that may have happened to me in high school. It relieved me of the pressure to get straight A's and "compete" for the top of the class. I no longer had to be driven by an external factor.

In college I realized how awful things were (for those that were driven by grades). You could look around and see zombies sitting in desks. Most weren't interested in learning or thinking critically... just worried about getting the "right" answer and "good" grades.

I remember the first time I "failed" and got detention in high school... it was my senior year. Thank goodness I hadn't gotten it earlier because after experiencing it, it wasn't all that bad. In fact I actually sat down and got my homework done then.

Life's too short to worry about grades and failure and we only make childhood shorter by placing this pressure on our children so early.

The thing the girl said reminded me of my little nieces and nephews. They are in either Highschool or jr high, whenever I've asked them what they want to study, or do in life they just say "something easy". By easy it doesn't mean not challenging or that requires no effort, it means that they are certain they're going to pass, that's all they care about. And since they haven't experimented/looked in other fields, for fear of failing, they are also not sure what they want to do at all. When I talk to their mother, she just wants them to be teachers like her, because she could probably get them a job.

So yeah, it is pretty harmful. Let them fail.

Trying to get a 0.0 GPA in a quarter/semester/year really is a worthy challenge. Much more difficult than you would think. I tried 3 separate times - closest I could get (without dropping from classes) was a 1.0.

I believe being spoiled by many of the finest computer, console, and arcade games of our time, as well as being a heavy book addict, made me bored of the "correct" way to play school at the rather early level of 2nd grade. So I started looking for ways to play the game to make it more fun.

In high school, hearing the words "wasted potential", were like a trophy to me. It showed the teacher respected my knowledge (which I obtained for my own pleasure and proved at will by getting random A+s), but frustratingly knew it was not a result of the system they were paid to run. The few really awesome teachers I had, did not get this treatment. I could sense their love for knowledge, either in the way they were actually passionate about the subject they taught, and/or the way they treated students with respect. For these extremely rare few, I was willing to pretend to play by the school rules out of mutual respect for the teacher, not the game.

Unsurprisingly, many of these truly awesome teachers were fired or forced to transfer schools. The highly competitive high school had too many parents complaining to the school board about their kids being given a B, and even tried to convince the teachers to erase records of cheating (they being honorable ambassadors of knowledge, of course refused). This was the final proof to me that the system was a joke.

"Wasted potential", I learned was a reference to the potential of the system to use you to perpetuate itself. It had nothing to do with your own potential future, which was always your own great responsibility (thank you Uncle Ben). I had 127 recorded absences in 12th grade. I still graduated, as I expected - the only thing more important to the school than student attendance, was public appearance.

I remember in high school the only things I ever learned well were things that weren't taught there, or that I'd learned myself before going in. I'm still trying to recover from the hit I took in subjects like math and physics; I loved both when I was younger. Like many others I happened to be lucky to have discovered computers before going into high school, or I know AP Computer Science would've killed those for me too (haven taken it).

College dropout now. School's never "worked" for me. But I was born into a family where blindly grades were everything, and I'm pretty sure this had more of a negative than positive effect on me.

The key problem with schools is that they teach you to not just respect authority, but also to defer to it. In the real world, conforming and deferring to authority only makes you mediocre. In order to succeed, one needs to develop the mental framework to question authority and challenge the status quo. The current schooling system, for the most part, does not encourage the development of such a mentality.

As someone who grew up in India, I am all the more sensitive to the role of authority. Thanks to massive density of population, weak economy, and cultural norms, Indian institutions promote the worst forms of deference to authority. However, rather than culture, in countries like the US, the schooling system is the primary source for teaching people to conform to their peers' expectations and to defer to authority. The American society, in general, is quite different from the hierarchical structure that exists in American schools. In the real world, you have more freedom to question authority. Life is also different for adults because they are often more mature than kids, and are in positions where they have more choice than in the school. Schools should thus change to mirror the society, while still understanding the fact that school students are mostly immature.

Often, such suggestions for reform are mistaken for 'give them the choice to study what they want'. On the contrary, throughout secondary school, students should necessarily be taught all subjects and forced to sit through all classes. But, be careful to note that this does not necessarily imply that they should be judged on all these courses. The key problem in modern schools is that the 'judgement' system is broken. Just like performance review systems in most companies. Schools should take a leaf out of the HR policies of companies like Netflix [1] and do away with formal judgement/performance review processes.

InclinedPlane 10 hours ago 2 replies      
I'm always reminded of an essay by, I think, pg about how school works the opposite of real life. In school you are effectively judged by your failures, and thus are encouraged to avoid failing since it will bring down your grade point average. Moreover, the impact of your successes is capped, and at a fairly low level due to grade inflation. Once you've achieved an A/4.0 there is little incentive to put in more effort.

In real-life, however, things are reversed. Being mediocre yet diligent at doing busy work in a variety of subjects, which is precisely what earning a 4.0 implies, is not terribly valuable. Instead what matters is excelling at a small number of things, perhaps even only one.

The conceit of our educational system is that the way it works encourages students to become "well rounded", but it does nothing of the sort and works stronger against doing so than towards. Students are discouraged from developing passion, discouraged from exploration, discouraged from putting forth more than the minimum amount of effort, discouraged from developing their own interests and their own points of view.

This actually hit my previous company in a software context.

We would number our hotfixes sequentially. Many would be items demanded by a single client, so would get deployed as hotfixes only to that customer's site, and just rolled into the main trunk for the next quarterly release for everyone else. Clients would always be notified about hotfixes going onto their live sites.

One savvy client noticed the hotfix numbering sequence. Naturally, that ensued quite a number of extremely awkward discussions as they would regularly ask why our software needed so many hotfixes (tens per week) and why they weren't entitled to all of them right away.

Solution: a new policy to randomly generate hotfix numbers. Which of course led to the next problem, that now the sequence was not obvious from the names, so dependent hotfixes would sometimes get deployed in the wrong order. Why can't anything be easy...

There is some practical relevance to software development here. One shouldn't expose sequential IDs (a.k.a. serial numbers) to the public for anything non-public.

I see this Hacker News post has a numerical ID in the URL, for example; I can estimate the size of Hacker News given enough of these numbers... More directly, I can modify that numerical ID to crawl Hacker News.

Many sites do this; it's generally better to generate a (random or hashed or generated from a natural key) 'slug' to use as the key instead. For example, Amazon generates a unique, non-sequential, 10-digit alphanumeric string for each item in their catalog.

The really funny thing for me, is that I remember Monday the 19th of October very differently. Sun had called together the biggest press conference they had ever had, they were announcing that Sun and AT&T were going to work together to jointly build one true standard UNIX which everyone would run, with interoperability and reliably across the spectrum of computing. And that AT&T was putting 1B$ into Sun and had options to put another B$ in.

Eric Schmidt, who was the lead on that press conference, and Bill Joy who was his technical backup, were really confused why all during the conference reporters kept running out of the conference room to make phone calls. They didn't believe that their announcement was that big but everyone was clearly quite agitated.

The clipping service didn't find a single major daily that covered that press release that day. Magazines that had it and were embargoed went with it. But it got little to no coverage.

He was half right, the primary halon system indeed failed to discharge. But the secondary halon system observed that the primary had conked and instantly did its duty, which was to deal with Dire Disasters. It had twice the capacity and six times the discharge rate.

A bit of explanation: a VAX 750 is about the size of a large washing machine. It does about 1 MIPS, and can handle a surprisingly large number of serial terminal users simultaneously due to the I/O design. An RA60 is a hard disk unit, but not the sealed "Winchester" technology that IBM was promoting (and certainly won). Each disk pack could store 200 or so MB on several 14 inch platters that were held in a clear pack. It was frightening, expensive, and remarkably rugged.

By the time I was part-time sysadmin of one in 1992 or so, they were totally obsolete, and my 486DX-33 running Linux was faster at everything... except effective serial I/O for multiple users.

When it finished they turned to me with expectant faces and I said in an avuncular manner, "This is your most important command!"

This isn't exactly an app or traditional tuner, but I recently put a TronicalTune unit on one of my guitars (Les Paul Studio -- it's my project guitar) and it's the coolest thing I've ever played with: http://www.tronical.com/ Makes it so easy to switch tunings, the locking tuners are great (learning to string it up properly takes some time, but it's worth it), and it doesn't add too much weight to the headstock. Can't recommend it enough for guitarists with compatible equipment; really wish they'd make one that would fit on my 8-string or my PRS!

Good work, thank you. I have been looking for a free guitar tuner and I have had varying experiences with the ones I've used.

I mostly use a linux native app called lingot. It does the job but has small annoying bugs (settings file is not parsed properly, my ALSA device CARD:foo,bar=baz fails because of the colon character, I'll write a patch one of these days).

This guitar tuner works, I tuned my guitar succesfully with it but it was a bit painful. I'm on Firefox 27.0 on Linux, using Alsa, no PulseAudio. I am using a Microsoft LifeChat headphone + microphone laid on the table before me that is good enough to tune my guitar with Lingot. I would have tried Chromium for comparison but it seems I have a version that is too old.

There was a very bad latency, around 1 second from playing a note to seeing feedback on the display. The information I got back was decent and good enough to get my guitar in tune. Overall the quality of this was somewhat comparable to a cheap guitar tuner from the 1990s with an internal microphone. But I think the culprit here is the platform (ie. browser + audio frameworks) rather than the quality of the app itself.

What platform(s) have you used with tuner and how did it work out? What browser, OS and audio system did you use?

If you want me to help out testing this app, please reply and tell me what to test and I will.

I also made and released a chromatic instrument tuner using web audio input a while back:

http://www.leshylabs.com/apps/tuner/

I haven't looked too closely, but my technique is probably a bit different. I use FFT only to gain a hint of where to look. FFT itself, at least in the form that is built into the web audio api, is not accurate enough for a tuner. Instead, after FFT tells me where to look, I use auto-correlation to scan those frequencies.

I may have released too early, because back when I wrote this web audio input only worked in limited versions of Chrome. It didn't even work in the main release without changing flags, and so my release went mostly unnoticed on the internet.

I haven't checked in a few months, but I've been waiting for mobile support to catch up. Firefox mobile beta started somewhat working a few months ago, and I don't know if that moved up into the main version. While Chrome works well on the desktop now, on mobile I don't think they have any working web audio input support, unless that changed recently.

https://en.wikipedia.org/wiki/ReedSolomon_error_correction

Or to top that, imagine a computer where the entire memory space, perhaps shared with persistent flash memory, was encoded in this manner, so that even the filesystem was protected against bit flips.

When I was doing Mac repair a few years back, the majority of the PowerMac G5s that came through the doors died premature deaths for two reasons: the ram was in a bad spot which caused the board to bend and crack on insertion, and the ram was non-ECC so it was notoriously difficult to isolate a bad ram chip. It was the most unreliable Mac I ever diagnosed, by perhaps an order of magnitude.

Contrast that with the Mac Pro, which used ECC and was so much more reliable that I don't remember seeing a single Mac Pro fail in the 3 years I was there.

Imagine how stable a ReedSolomon computer would be..

But I enjoy the premise of what Uzbl is aiming to solve. It would certainly make for a richer array of web-related software components, with plenty of uses beyond just web browsers.

i can't really use this project now that my main os is osx(i frequently boot from my ssd with archlinux on the mba), but

i absolutely love this project. it's amazing,

the only thing i'm a little sad about is that i never wrote the pass plugin i wanted for password store [1]. but hey you can still write one

the main author moved, but there are fairly active forks[2].

the amazing thing about this is that you can write plugins in any scripting language you want. you can pretty much hook it's basically a mighty scriptable version of webkit.

here are a bunch of scripts you can use to extend it with [3]

on a sidenote, a completely different, but also interesting approach are conkeror [4] and luakit [5]. though luakit seems abandoned too. luakit is kind of a lua webkit browser framework with sane vi like defaults. conkeror is an emacs for xulrunner, however keep in mind that since firefox is taking over the role of xulrunner you might not really need xulrunner at all.

This is essentially putting a Kinect in your phone and hooking it up with hopefully high-level APIs. It may take 2-3 years to make it into regular phones, but when it does it will be huge. Apple's acquisition of PrimeSense (the makers of the 1st gen Kinect) means they're also working on this.

To give you a real-world example: when I started BarSsense (http://www.barsense.com) the core problem was tracking the path and velocity of a weightlifter's bar. I bought a PrimeSense camera because it can extract a lot more data and with greater accuracy out of an image than a regular camera. After some prototyping, I decided to use a 2D camera and deliver the software as an app because I thought wide distribution and ease of use was more important than the fidelity and correctness of the data - ie, the "worse is better" approach. When these cameras make their way into regular phones, "worse is better" will suddenly become "better".

"Imagine measuring your room by just walking around in it." Yes, and imagine transmitting each of those footsteps in real time back to Google, so they can have a map of your room, too, in case they, or other parties, ever need it.

I was just having a discussion yesterday with a friend who works at Google about what data they store when you query their search engine. Every single keystroke, including backspaces, is stored. They don't just know what you ask. They know how well you can spell and know how well you type, not just in general but down to specific letter sequences. With this data, they can tell if you are regularly more impaired (fine motor control) at some times than at others, or if you're growing more impaired over time and match that against the content of your queries, etc.

"Phones that don't limit their boundaries to a touchscreen", meaning, we're not satisfied limiting our knowledge of you to just what we can extract from what you enter and how you enter it and when on a touchscreen. We want to know every step you take, when you sit, when you stand, how and where you walk.... SO much more data about you and your world that we can mine for treasure!

I'm not saying that Google is evil. My friends at Google certainly aren't. It's just that they are like kids in a candy store with unprecedented access to data and so many great, new algorithms for extracting information from it that they are just loving it, the way geeks would. But we're really going down a rabbit hole here.

My submission:

3D Printing is a big data problem where the data is not being collected. Sensors in desktop 3D printers are usually restricted to simple limit switches on the axes.

We would use Project Tango for a real-time feedback system for 3D Printing. Initially, we would demonstrate a simple functionality: recognizing when a print is failing and instructing the machine to stop, rather than waste more material. Next, with the help of the open-source community, we would expand functionality to dynamically adjust machine instructions to compensate/fix problems observed during the print. Here are a few examples:

- adjust bed height for different layer heights via software rather than manual hardware tinkering

- dynamically change extrusion rate if underextrusion/overextrusion is observed

- detect if belts are slipping & correct extruder positioning

- pause print is no filament is extruding

- intelligently resume print if stopped (e.g. power failure)

- inform slicing software if/where/why a print fails so the software can reslice and repeat properly

For users, no new hardware will be needed besides Project Tango - a computer will stream GCODE instructions via USB to a RepRap-like 3D printer (e.g. Makerbot, Ultimaker, etc.). Project Tango is precisely the breakthrough we have been waiting for to make 3D printing more user friendly.

Here's the best idea I can think of with this technology.

Imagine taking a scan of your pantry, refrigerator, and/or laundry room. Then mark everything as what it is (e.g. "box of cheez-its", "milk", etc). Then come back a few days and do the scan again and it'll tell you what's missing. Once you return from shopping, scan again saying what the new items are (even if they aren't what was there). The software would probably need to recognize certain shapes so a slight rearrangement/movement doesn't change. It'd be like history/bookmarks/favorites for perishables!

Here's the application I thought was immediately obvious: memory palaces.

Based on the old mnemonic trick of taking a real physical location that you know well, and associating memories with objects in that space. The digital version of this would be having files and data stored in a "physical" place - although they're not solid, they'd be tied to a single location.

Harder to organise, but I know several people who have completely filled their computer's desktop with shortcuts, because they don't like futzing around with folders. The folder metaphor isn't the be-all and end-all, there are times when it's appropriate and times when it's not. The metaphor of icons that are dragged around the screen is limited by available screen space - Project Tango gives you a house-sized (or even just room-sized) 3D space to play with, more than enough for all the files you could need to be immediately visible.

The main risk is that my virtual room could end up as messy as my real room.

I don't know how anyone could make money from this, but it would be really damn cool.

I understand the idea that you can get the exact positions of the surrounding, if you have an accurate position of the device. But how are they achieving that? I don't know of any such small tech capable of being accurate to 1cm, without external help.

I don't see how can they do this without an accurate position of the device.

An example when it breaks down without the position information:

Pointing the device perpendicular at an uniformly colored wall and moving parallel to the wall. Then the visual information is undefined and you have to rely on very accurate position sensors( which don't exist ) to correctly scan the environment.

Some (perhaps even some division of Google itself), will do something totally asinine and attempt to subvert the original intents of the engineers and designers who are currently involved. But that's what happens with any new technology that broadens access and visibility. I don't believe anything Google does is inherently 'evil' on its face.. unfortunately, given their reach, they are a natural access point for some federal agencies to execute their primary tasks, as they fall under the same vague, broadly defined national security laws as we all do. The only difference is that we don't run the Internet and its major consumer touch points. Google does and they need to make money from their capital investments. It would be smart to use it and do something cool.

So it's probably more a cultural thing, than a slightly shifted timezone.

While this article is interesting, I don't get the obsession people collectively have with specific times and needing timezones. Don't like getting up when it's dark? Get up later. Yes, that requires participation if you depend on others' schedules. Schools are particularly notorious, starting at ridiculously early hours. (My kids would have had to get up at 5.30 or so, but I created a private school for them, and it starts at 9. Works fantastic for them, they can stay up a bit later and play. There's no traffic rush for the teacher, which is good. A much better solution than starting at 7.30.)

I imagine if there were no timezones, people would cope with this better, since they'd be forced to. Instead of saying "kids shouldn't be up past 8!" they'd actually stop and think about it.

The Olson tzdb used to have support for a solar-noon time zone for Saudi Arabia. I forget the specifics but there was a need for solar noon and a religious observance. It was just recently removed due to constraints regarding the size of unsigned chars.[^1] It would be neat to remake the map with the tz shapefiles and animate it a la xearth.[^2]

Earlier this year I was curious as to what would happen if we used a clock that was actively calibrated to the solar high noon. I made this little web page here: http://mseiler.com/highnoon/ that uses your geolocation data and a few date-time and astronomy libraries to do just that. It tells me that in NYC the time is shifted by about 11 minutes and that number varies a lot throughout the year.

It would be a very different world if we were to set up meetings using the actual solar time calibrated to the date and location of our meeting points!

If you don't like having your time wrong, you could use my decimalised time system that rotates the numbers based on your geolocation so that solar noon where you are is always at the top of the clockface.

LinkedIn is not using email contacts to find people who have an account already plus.google.com

This obsession with collecting users (dead or alive) reminds me of Gogol's Dead Souls - companies trading in users (who may or may not exist) in order to boost their standing and taking out huge loans on the basis of their illusory popularity. Even illusory users can have some value, just like the dead serfs in Gogol's tale, and like the dead serfs, their value is not in their existence, but in being entries on a ledger of chattels.

It doesn't matter to LinkedIn whether these accounts are used or real, because they are judged on basic numbers like how many users they have. Since real money is involved and salaries and careers are riding on this number going up, they'll employ all kinds of perverse and intrusive tricks in order to inflate that number every quarter for as long as it is a measure of success.

Really surprised by all the comments here. This seems like a solid business decision by LinkedIn, riding the line of what a user is willing to accept and balancing it well with the potential rewards.

Look at every famous company and you'll find tactics that you don't agree with, and sometimes downright illegal (Path).

If you're not willing to do desperate things, to do what is necessary for user acquisition, good luck trying to build a successful business, because pure blind luck is exactly what you'll need.

Stuff like this is what really separates successful businesses from the failures. It was never about some grand vision, or some belief in connecting the world. It was about figuring out how to acquire users, retain them, and monetize.

I've never intentionally shared my contacts with LinkedIn and yet I get shown names from my address book. One was my teenage son and I tried to connect thinking he'd signed up for some reason. Nope, he'd never even considered it.

I don't know where LinkedIn got my contacts from but I suspect I must have missed a setting when I briefly installed the mobile app a few years ago. Some of the email addresses they have are out of date so that adds weight to my theory.

Your headline is extremely misleading. They are a public company and thus it is quite unlikely that they are lying about user numbers. That is a fantastic and relatively speedy way for a CEO to go to jail.

What they are doing is using your contacts list to mislead you into believing that many of your contacts are already on Linkedin. Once they get you to connect with yet-to-exist accounts, then they can legitimately spam your friends saying that you want to connect with them. Interesting strategy, but it will earn them some backlash.

I get this all the time on the "suggested connections" page - names and email addresses extracted from my Gmail contacts, but the name is not a link to a profile (on normal suggested connections you can click on the name to see their profiles). I could easily spot those and not request to connect but it can be confusing for non-technical people.

What changed recently is that these fake profiles are also listed as having "shared connections" with me which is hard to believe considering those are not Linkedin profiles at all.

kaivi 20 hours ago 0 replies      
I have used my Gmail box since early beta, and most definitely, a fraction of people I have ever contacted are no longer alive. There is no way for me or for LinkedIn to determine that. They may use an aggressive strategy to get new sign-ups, but that's just their way of shoveling money. Death is natural and inevitable, and I believe that we must raise people's awareness of it. I'd say deal with it and don't ever let the reality offend you.

Here is a good speculation from xkcd on a related topic: https://what-if.xkcd.com/69/ With it in mind, how valuable would a database of the deceased be in 100 years from now, if we start gathering this data today? For example, mining the internet for history on relatives would probably become a business of it's own, and as a consequence, ancestor's deeds would be much less romanticized than they are today.

Just go to LinkedIn, in the top drop down menu "Network" select Add Connections. You will get a list of "imported" users. That's the users LI tricked you to give to them when they asked you to grow your network and you let them connect to your gmail or other email. They sucked in not only your address book but probably all people that ever emailed to you.

In that list just go through all users and check all that don't have little LI icon next to them (no LI profile). Click Delete button and you are all set. You can just delete all of them if you want. I clicked on "allow access LI to GMail" by accident once, when they gave me some tricky pop up during my roaming on LI. Very shitty behavior IMHO

michaelochurch 16 hours ago 1 reply      
My issue with LinkedIn is philosophical as well as practical: it's fucking dangerous.

In the career game, most of us have to be spies-- careful and immensely tactical with information-- in order to have success. A lucky few are so good at what they can do that they can shoot their mouth off (like I do) and tell the truth, for the good of the world. But most people will need to reinvent their histories at least once, and LinkedIn makes it harder to do that.

The upside: participation in a rather boring social network.

The downside: you can never reinvent yourself, because you've put too much information out there and people can find out that you actually were only a Director, not a VP, at that job in 2007, or that you spent 4 months at a shitty startup you've since taken off your resume.

But now it's almost socially unacceptable not to have a profile and actively play the game (so as to get double-digit endorsement counts in your specialties).

To me, LinkedIn seems to be a way for those in the slave class to polish their own chains.

What a load of bull.

Let me tell you a story about John Sculley. Former CEO of Apple ( http://en.wikipedia.org/wiki/John_Sculley )

I met John 4 times. He contributed to a charity that I was working with. I didn't think there was any chance he would remember me. Years went by, then I got a linkedin invite from John wanting to connect.

John Sculley wants to connect with me? Really? This can't be real. I'm "famous" but I'm not that "famous" and I barely met John, no way, has to be fake. So I report it to LinkedIn. A second friend gets a similar invite, and she has never met John, but was a contractor for Apple, and at Pepsi when John was. I have her report it to Linkedin as well.

Linkedin rushes around, calls John, doesn't get anything but a generic voicemail. 72 hours later they remove the account. 4 days later John's wife gets back from a trip, and checks his email and sees that linkedin has removed his account.

Ooops. I have caused a legit person to have their account removed.

I'm not saying LinkedIn users are all "real" but they do seem to go out of their way to have what is described in this article not happen.

It's really great to see perpetual interest in collaboration on LaTeX documents. I hope you have great success (not sure I have a use for it now but will keep you in mind if I ever do). I also expect to recommend it.

Unfortunately a lot of my own documents are really hard to handle with editors -- I tend to write very long documents split across multiple source documents in a tree for easy management. I wonder if there is room in an offering like this for something more like an online IDE rather than just a editor for a singular file.

Thank you for open-sourcing this! At the moment I'm using sharelatex to keep a version of all my equations "alive" since every time someone tries to resave my word documents, the equations become rendered to images.

Unfortunately for me, Latex hasn't gained traction in our department. I think the main barriers to entry, for our lab at least, are:

1) Local installation is more difficult than installing Word. Sharelatex and other cloud-latex solutions solve this.

2) Word's comment and review tracking system is more intuitive. If you're reading a document electronically and want to insert a comment or make an edit in word, you just do it right there. With latex, you can use synclatex to go back and forth but this extra step is actually a non-insignificant barrier. Also, with latex, is there a way to make and see comments in the pdf/preview but have the comment also live somewhere in the source, AND have the comments be editable in both places? I suspect the answer is yes, but I just haven't found the right tool?

I haven't unlocked the "history" feature in sharelatex but does it come close to this?

This looks excellent. I'll certainly try it for my next paper and will see if I can lobby our university to pay for the hosted version.

I'm assuming universities are what you are aiming for? I think you should focus on CSy departments.

Could also target conferences/journals i.e. allow them to offer access to the hosted version for people collaborating on a paper for that journal/conference.

From a business development POV, I think it would make sense to wade through university pages and collect departments that offer Latex-Templates to their students as potential contacts.

Just tested this out with a 150 page document split across several folders; it compiled quickly and I really like the way you display the logs and warnings. Looks great! And I really appreciate your making it opensource.

Integrating this with github a la travis-ci would be great, obviously one would need to be able to make commits to the repository too; I'm not sure if it would be great enough that it would induce people to start paying for the service if they weren't already, though... although I'd sure like it.

I'm not sure what sort of use-cases you are seeing already, but this seems most useful to me personally for last-minute edits to coauthored papers & grant proposals right before submission. Nailing down the final version can be a real pain in the ass.

A few other minor observations:

* uploading a zip file didn't work, but I'm on an old version of RHEL and made the zip with Ark, so... who knows

* after accidentally drag and dropping a bunch of .bbl, .log, .toc (etc) files, I didn't see a way to delete more than one file at a time, or how to undo a file deletion.

* I also couldn't figure out how to move a file from a subdirectory to the top level directory

My wife started out with www.writelatex.com to write her dissertation. The auto-compilation really slows down once you get beyond 30 or so pages.

Also they don't have Git integration either, which was a deal breaker for my wife.

She's since moved to using RStudio locally + Git.

She says, "If you have Git integration, the auto-compilation feature would get me back from RStudio."

We've also thought about using Grunt to build our own auto-compilation feature.

Say you were a shady Bitcoin banker with 5000 BTC in deposits, and you wanted to steal 1000 while still looking like you're on the up-and-up by implementing this idea.

First, you announce that you only have 4000 BTC in deposits. Then you build this tree, and at the very bottom layer you add a node with a -1000 balance. You pair that node with your (or a conspirator's) real node holding more than 1000 so that any node above yours (read: everyone else) sees a positive balance at every point in the tree. Everyone can verify they're in the tree, the numbers add up to what you claimed publicly, but you're now successfully running a fractional reserve! And the only way to uncover such a scheme would be to publish all of the balances for every account.

Am I missing something?

Edit for clarity: the node you pair with is your own, so that no real user sees the negative sum.

Not to discredit the very capable developers discussing this, but in the interest for giving credit where credit is due, didn't Peter Todd suggest this back in his Bitcoin 2013 presentation on off-chain transactions?

Or, just use a system like we use on Bitalo, where fractional reserves are impossible because of use of multi-signature Bitcoin addresses, which means funds are specifically tied to user wallets and exchange operators cannot use them without user's signing all transactions by himself.

The developer is Gregory Maxwell, aka nullc. Here's a very interesting thread in which he proposes that the bitcoin community should demand that every bitcoin exchange (and every other type of service which can hold bitcoin on your behalf, like webwallets) continually prove that they are not fractional reserve. In other words, proof that if every user of the service simultaneously tries to withdraw all of their bitcoin, then the service would be able to honor all withdraw requests: http://www.reddit.com/r/Bitcoin/comments/1yj5b5/unverified_p...

"I think that as a community we should start demanding these services continually prove that they are not fractional reserve. We cannot effectively eliminate the need for trust in these sorts of services, but we can certainly confine the exposure and eliminate a lot of this drama. With Bitcoin it's technically possible to prove an entity controls enough coin to cover its obligations and even to do so in ways that don't leak other business information, and so we should. But this isn't something specific about MTGox, it's something we should demand from all services holding large amounts of third party Bitcoins. I wouldn't even suggest MTGox should do it first, rather it sounds like a great move for their competition to differentiate themselves."

Here's the takeaway:

"This would leak the total holdings, and some small amount of data about the number of accounts and distribution of their funds, but far far less than all the account balances. Importantly, though it could be implemented in a few hundred lines of python."

In case anyone from Coinbase is reading: you have a unique opportunity to be the first webwallet service to implement this, and thereby make the entire bitcoin community instantly fall in love with you. It would also set a minimum standard of quality for webwallet services in general, which would add a lot of value to the bitcoin ecosystem. It seems like this might be a pretty big business opportunity.

At first I was worried of what would happen if the exchange introduced fake nodes with negative balances at the bottom of the tree, but there would be no way for them to hide that without the first real customer up to the root finding out (there would have to be a negative node that he/she could see). This sounds like a great idea!

The big problem with this is convincing businesses to publicize their total customer deposits, which is extremely interesting information to competitors.

Though it could be a good way for new/small exchanges to differentiate themselves and gain trust of the community, which could force larger and larger exchanges to do the same until it's common practice (as mentioned has happened with provably-fair gambling sites)

I backed the project, and think it will make a great gift for my nephew. It's something he can grow into, where he can read the book part with his parents right now, and then start doing the problems as he gets older.

I think this project did well for a few key reasons:

1) STEM, STEM, STEM and code, code, code. The timing is right. Look at all the coverage this got in big mainstream media publications. Here is a project to help your child get into programming at a young age.2) There is a need for introducing programming to children in an accessible way. There is some stuff on the market, but not that much, and this might be the first centered around a colorful children's book. I also think this is more approachable for parents too. A cold, clinical textbook would scare off many parents.3) Linda is attractive, bubbly and non-American (on a heavily American site). This never hurts with crowdfunding. The fact that she is female in a heavy male-dominated space helps too. I can't fault her at all for this, and why not harness it?

I hope it turns out well and that this is just the beginning for Linda and her books. I'm excited to read it with my future child.

I like the idea and I backed it. Book for kids can be as simple as picture books. Parents and mentors are the one supposed to help them to learn the hard stuff.

But I also want to say that I have some feedback for the video. I just thought there was too much "smiles". I don't know how to put it: but it's strange and weird to see someone posting a video of her smiling like literally every few seconds, throwing things every minute or so. A bit formal will be great.

There was too many moving. Scenes were constantly changing while the speech was on-going. It was hard to concentrate, pay attention to the dialogue and the animation at the same time. The main point wasn't delivered/pitched to me right away. I wasn't too sure what exactly would go into the book and how parents/mentors can help guide the kids in general from the video. Essentially, an ad that changes scene every 1 second is going to hurt viewers.

Here is another project (which I backed too), I am not trying to promote it (but putting out here is guilty of promoting it). Check wongfuproduction movie fundraising video on Youtube. That was a lot easier to grasp.

Just my 3 cents. Good luck.

For a long time I wrote off the idea of having a blog because it seemed vain. I don't usually have any great ideas that anyone else needs to know about, and my trials of learning new things are just the same as everyone else's. However, over the past few months I've realized that I was dead wrong. Watching a few good series of blogs like [1] and [2] has shown me that even if you don't have anything world shattering it is still great as a means to make learning more important.

Harold and the purple crayon is a great book that introduces programming concepts, but it doesn't beat you over the head with any computer lingo.

This book is a neat idea and the illustrations look cool, but here is one concern:Why name the main character Ruby? Good kids books are timeless and ruby the programming language is not, and it dates the book too. Why associate any programming language in particular with programming concepts like sequences or sets? That seems like a message from "learn to code" school. So does DRY to a lesser extent.

Would really like to see a couple of starting pages from this book. I hope she has an idea about how to deliver this stuff to children: coding by itself is pointless for somebody who does not even comprehend the manifold of applications it can solve. Video games are fun, because they exploit the basic survival instinct within us. With programming, there is no low hanging fruit to reach for a child, as the mental link between writing code and receiving a reward is build by experience, which minors lack.

I find it hard to explain the fundraising which went way over the goal, without including gender into equation. Anyway a pink-colored children's book about tech stuff, written by girls, sounds comforting in every way.

I've been watching this project since it was first posted on HN, getting giddy over the thought of it. I love the execution in how this book will teach kids about programming. I also love that the main character is a girl and that the whole book is cutesy.

I plan on using this both for my own enjoyment, and sharing it with a soon-to-be five year old boy who will be absolutely in love with the little animal/Android characters.

I'm toward the end of a rough patch financially, and usually pass up supporting projects on Kickstarter for this reason... But I couldn't resist, and ordered the double package.

Congratulations on the extreme success, Linda! I hope you find the process enjoyable enough to continue the series for years to come. I also hope the app or even a little indie game will be possible to create in the future (I realize it won't reach the $500k goal.)

As a final note - I just thought of the possibilities of this being implemented in a classroom!

There have been countless posts on HN where the author has made some amazing sales on e-book, SaaS MVP, apps, other software, and so on.

If I am the one paying for an office at $500 a month that includes all electricity usage, is it fair to plug in a ton of mining hardware and profit / subsidize myself? What if I manage to use more than $500 worth of electricity?

Is shared space even setup for monitoring individual renter's usage behavior? I don't think so.

Bummer...but also exciting, since Adhoc/Beta distributions and access could be massively improved by being handled first-party by Apple. Maybe now it will be!

I've long been using TF for adhoc beta distributions of my iOS apps. Looks like there are only two options left for that:

    * Hockeyapp, starting at $10/month    * Host your own IPA on S3 or elsewhere. 
The downside with the latter is where TF added value: per-build access settings, notifications, teams, and feedback. You'll have to approximate this now by mucking with which devices are listed in your provisioning profile.

I open-sourced my iOS build script recently. It'll take care of everything for you -- downloads your provisioning profile from Apple's dev center, builds, codesigns, archives, and uploads to S3. https://github.com/splinesoft/SSBuild

I abandoded this because I longer have access to a Mac since I stopped iOS development a while ago, but ping me if you're interested and you want to try to get it to work. It doesn't come close to the features of something like TestFlight, but was designed for in-house use by a team who needs access to bleeding edge builds without developer intervention.

It's probably just me, but it took me so long after visiting the site to figure out what they actually DO. Wording like, "BRING PEOPLE TOGETHER TO Share Your Passion" and "IT STARTS WITH AN IDEA" is vague and gives me no idea of what the product or service was.

I saw something about selfie tickets but had no idea what that meant. Do you take a selfie on your phone and then it's part of an e-ticket? Do they print tickets with your face on it? Is there a web backend? What does the mobile app do, specifically? I feel like there's not enough to-the-point descriptive copy.

I navigated back to the homepage and kind of got a better idea of what was going on:

"Create an event page and start selling tickets in minutes."

Okay, makes sense.

"Run event-day like a pro with a full mobile box office"

What's a mobile box office? Is it an app that lets me scan tickets with QR codes? Is there communication between mobile devices to validate tickets using NFC or something?

Please take this as constructive criticism. Good luck with your product! :)

This is cool in terms of self-expression and making the ticket more personal, and props for trying something new and building this in the first place, but does it actually solve a problem? I agree that the hassle / un-naturalness of scanning everyone in for smaller, more casual events is a problem, but I'm not sure if this solves that problem.

Unless an organizer makes this mandatory for all attendees, it's more than likely that only a minority of attendees will actually take a selfie of themselves for their ticket. And if say, 20% of attendees took a selfie and 80% did not, how does this solve the "scanning problem" for organizers?

I can see how this might be interesting for attendees to stalk who else was there but what is the value prop for event organizers? Would the event organizer get other info from the user such as email address? Why is this going to make me choose TicketLeap vs. TicketFly vs. TicketMob vs. Brown Paper vs. Eventbrite vs. anyone else in this insanely crowded industry?

I disagree very strongly with the principle that services should be purchased with a photo. I will share a personal experience.

Traveling from Luxembourg to Brussels by train I made an arrangement for a room via AirBnB. It being the first time, they asked me for ID, and Credit Card information. I provided that. By the time I got off the train I received a response from AirBnB that my reservation had been canceled due to the fact that I hadn't provided a photo of myself for AirBnb. I believe the reason was because they wanted to know that I was a "real person", but the exact phrasing escapes me. This was not the case since I provided a photo of my driver's license as my ID. As a result I had to scramble to find a room in one of the most expensive cities in the world for this at the last moment (which was expensive).

I strongly disagree with the idea that "your face" should be integrated with a purchase. I strongly agree that your identity which includes but should not be limited to a subset of "your face" should.

If you are proceeding down this path I recommend having a user select a photo, rather than taking a self portrait.

Good Luck.

I clicked the link because I thought it was an app that would give someone a ticket every time they took a selfie. Like a parking ticket. Selfie ticket.

Ha, my first thought was a service that let's you give warning tickets to people who post 'selfies' on Facebook. Sign up today to join the "Selfie Police".

Props on the innovation. Devil's Advocate: Barcodes were put in place to speed up mass quantity entry. This might cause a lineup as the ticket-taker is now a 'bouncer' and has to verify each persons physical identity. Have you tested this model at any fairly large events?

That's some cool software. It would be cool is they applied their deep understanding of Ruby code to a code browser.

Often times to understand how a piece of Ruby code works it's not enough to just look at the source of that specific method. For example if I type in 'ActiveRecord.find', the second result is the one I want, ActiveRecord::FinderMethods.find, and I click it. The documentation is a bit long, so I click 'view source'. The code is short and sweet, but not very enlightening, it's just a wrapper around 'find_by_ids'.

Now luckily 'find_by_ids' is a public method so that's documented and I can search for it. But almost guaranteed at some point the code is going into private api's and I can't use the documentation anymore to understand it.

This is why I always have a local checkout of the Rails code and any other big gems, so I can just 'ack' my way through the source from identifier to identifier.

It would be super awesome if omniref in that 'view source' block would find identifiers, and try to guess what they refer to, and make them clickable so we could really just browse through the source. The user interface is perfect too for fuzzy search, as it shows the item its most confident in in the main window, but has the rest of the results in the bar on the left side, can't go wrong with that!

Coming from Java the biggest surprise to me was a lack of good API documentation for Rails and Ruby gems.

Javadoc used to drive my productivity. It is quite frustrating sometimes with Rails that more often than not I can't find good api docs.

Rails and various Ruby gems have very good tutorials, but sometimes no api docs at all.. Tutorials are great for getting started, but you're in trouble when when you want to do something slightly unusual.

Slowly I'm realising that to be really good with Rails you need to look into the source code of libs you're using to get a better grasp.

As an example, I wanted to find out if it was possible to do something with ActiveRecord.to_json that I haven't seen in any tutorials. Spent 10 minutes searching for docs and then looking at the code.. which in Java would have been done in 20s.

Having said that, I really like Rails and enjoy a lot of productivity gains. I just wish it had better api docs.

What it tells us is simple and people keep trying to make more of it than it is.

Users are leaving Facebook in droves. Facebook is buying back users who's attention they have lost.

People are migrating to other services that offer a better experience for the task at hand. This is what Facebook/Google/Microsoft keep forgetting.

FB bought Instagram because their own photo feature wasn't as good and that's where they sensed people would be moving to. They've mostly left IG alone and it's been good.

WhatsApp is a better IM experience. Facebook buys them to get back users that have left.

The thing to remember is that people leaving something like Facebook isn't "I'm deleting my account", it's inattention attrition. Facebook users don't die (mostly), they just stop caring.

So FB buying WA doesn't mean much except FB is trying to alter its course. To their credit, they have the foresight to see they're failing and attempt a course correction.

If you are an engineering manager, you can see huge gains in team satisfaction and productivity if you are cognizant of issues like this.

My suggestion is to take the time to understand each member of your team, then create various interactions that can foster teamwork, satisfaction, etc. This can include:

+ Lunches or dinners - Going out to a restaurant together can give your team a reprieve from the stresses of work, while strengthening bonds. This tends to work best with extroverts. Dinners work best for singles and lunches work best for people with families (who may have to go home to a spouse and kids).

+ Movies - If there's a movie that most of your team wants to see, treat them. This may give introverts a more comfortable setting, since not everyone likes team lunches & dinners. I sometimes reserved a dark conference room and played episodes of Futurama (or some other TV show my team wanted to watch) during lunch, which worked just as well.

+ Outings, activities - Not everyone may enjoy a particular activity, like a hike or indoor rock climbing gym. But you can offer various activities to your team as opportunities to get to know one another. Don't make those who cannot or do not want to get involved feel ostracized, however. Make these optional events.

+ Code reviews, paired programming, tech talks, hackathons - These exercises not only strengthen the skills of your team, but improve team bonding as well. And chances are, all of your developers want to improve their own skills, so any chance to do that is a good thing.

+ One-on-ones - Sit down with each team member and have a chat with her/him. This is not easy for every engineering manager, as it requires skills in listening, empathy, conflict resolution, etc. The goal here is to truly listen. If something is bothering your developer, chances are you'll be able to pick it up here, giving you a chance to resolve it before it becomes a major issue. I've had developers tell me they felt like these chats were therapy sessions, though I did my best not to make it feel so clinical (in some cases, these chats were over coffee, ping pong, a walk, etc). The point is, listen.

There are many more that I've forgotten and I'm sure you've done (and please do share!)

I never had a problem with attrition by employing tactics like these. And I don't mean to imply that no one on my team had depression - I am not a licensed therapist and make no claims that I can diagnosis this condition. My point is just that engineering managers who actively cultivate a supportive environment may reduce the likelihood of depression and foster greater satisfaction and productivity.

I experienced a very similar situation, resulting in a stress-induced tumor and heavy depression. This experience has completely changed my life and I'm incredibly happy that I got a second chance in life to live a better life. These situations happen because people learn and focus on how to manage the outside world but hardly anyone knows how to manage the inner world. Furthermore, most people don't talk about the stress or their fears and thoughts that torture them, not even with their spouses. The bad thing is that you can easily identify the first signs of depression or burnout and counter it with therapeutic measures, yet so many end up completely burned out.

You don't even have to pay a therapist, our minds can be trained to build extremely powerful therapeutic algorithms to avoid these situations. After my experience I quit my job as a business subordinate and started building a tool to help others manage their inner world better so that they hopefully don't end up where I did. Our approach is heavily scientific (we have two ongoing PhD projects to investigate and test our program) and we have just started out.

I'd be happy to connect with anyone who wants to share their experiences and thoughts on this topic. If you feel like it, drop me a line at: julian@appnroll.com If you are stuck in depression or a burnout and feel like breaking down, please don't hesitate to contact me, too - sometimes you just need to talk to someone. Hang in there!

One personal observation is that intense, extended development is mentally exhausting to the point that social interactions are difficult. I plan my work stints around my social schedule now, to make sure I'm well-rested for having fun with people.

Posture is also very important for my sense of self. If my chest is collapsed, I feel a subtle pain that sours my mood. If my lower back is clenched, I slouch my shoulders, and I get anxious. Exercise helps keep up positive energy and cast off anxiety. It also gives me time to relax tension in my body.

In my experience, both of these can factor into depression and social anxiety. I'm much happier when I maintain a good balance.

Small tip for the ones working on their own and/or freelancers. Join a co-working space/community! I did a few months ago and the difference is very noticeable. If you're in a large-ish metro area, chances are there are some around you.

Having lunch with other people, being able to ask around for help or feedback, taking part in events are all small things that end up making a big difference.

I have always assumed that depression is at least in large part a social illness.

Of my three children, two were born in Indonesia, and one was born in the US. My wife says that the experience was totally different, and that post-partum depression wasn't really an issue as much in Indonesia because she was surrounded by friends and family for over a month after giving birth (this culminates in a large party after 40 days which has a similar social significance to the older tradition of "churching" and the following "gossip" dinner in Europe). Even something which has as clear neurological strata as PPD has a pretty heavy social component too. (Now obviously this isn't to blame those suffering from PPD, but to note that our society to a large extent makes the problem quite a bit worse.)

Similarly I struggled hard with depression for some time after moving to Indonesia in large part due to the isolation it brought me. Eventually I overcame this by overcoming the isolation.

But beyond that I wonder if developers have a couple of additional strikes against them. I find that it is impossible for me to simultaneously think in machine operations and socially connect. Even when I am around other people, if I am thinking about code, that's isolating. Talking about code is not socializing and I am not sure it can be.

Additionally coding is a sedentary activity and exercise is one thing that also is shown to help avoid and treat depression.

I wonder to what extent we should think about structuring our lives as developers around an extended version of the Greek ideal adding a third component:

A healthy body, a healthy mind, and a healthy social life.

On the management side, I also wonder to what extent ensuring that outings involve mild to moderate physical activity may help too. Lasertag, or indoor rock climbing over movies. If there are people who can't, then looking at finding activities they can do too.

>It amazes me how often how to be happy pieces do well on Hacker News. I think delving into the notion that the more time we spend behind our computers, the less fulfilled we might feel in life overall [is a question worth asking].

I think unhappy people procrastinate more, vote more. The average vote is not given by the average reader, but one more depressed than average.

I think the issue is more that we have a skill that powers the world, but 95% of us are just business subordinates-- not professionals like doctors or professors, not even unionized-- and the 5% who have good jobs at any given time still live under the threat of an unforeseen issue (AI winter, financial crash wiping out the quant jobs, age discrimination, "Series A crunches") putting them back into the EnterpriseJavaDrone purgatory.

It's not "isolation". The software industry is a very depressing place. The pay (while not great) is solidly OK, but the status is low and the job security's abysmal.

Most software engineers have a skill that can do so much and end up having to use it to do so little.

Got into a video game programming private school, sneaking into 2nd year directly because I was good, was not accepted for the next year.

Apparently, it my fault of not trying to reach out to other people for building that school project. I'm more of an introvert, I was already taking anti depressant for 2 years. I'm at the opposite side of a narcissist. Apparently it's a bad thing in society, but nobody really talk about it either.

I was told things like "humans are a social species" and "teamwork is the most important thing in business and IT" etc.

I doubt being an extravert type makes a good programmer. There need to be a balance. But if you teach people programming, why not teach them teamworking too, or just gives bonus to students for their strength without making the teamwork aspect mandatory ?

> Even introverts are happier when they are around people they like,

Agreed. I don't mind spending time alone, but I love being around people I like. Usually others with a common interest. (And no, it doesn't have to be tech related. Horse people and swimmers are a lot of fun.)

Extroverts sometimes talk about themselves. A lot. Not that interesting :)

Awesome - glad to see someone trying to prevent hearing loss. I've had tinnitus for a few years now and am very protective of my hearing these days. Now that I'm forced to be more aware of it, I'm consistently amazed at how unnecessarily loud the world often is. Always have a set of ear plugs in my pocket!

Shameless plug: My start up also concerns audiology apps. Like the founder of SoundFocus, I've had hearing issues all my life- just had my second typmpanoplasty in November. Right now we have two apps that address tinnitus on iTunes. Check us out, www.bxtel.com
