Disclosure: My company was bought by 500px, I left after only 9 months of vesting, and I'm still bound by an NDA.

Andreessen Horowitz is backing 500px, I'm sure (but I have no specific knowledge of) that whatever paperwork they argued over the months that Andy was the new CEO was properly vetted.

In my opinion, Oleg Gutsol was incredibly talented in a wide array of things and has a good heart, but sometimes the CEO that's fantastic for the first 20 employees isn't the one that excels for the next 200. I'm sure this isn't the last we've heard of him. He'll start something new and succeed with it as well. He has an incredible ability to figure out how users will actually see and use your app and what motivates them.

I recently learned about the Breadfruit[1] at the National Tropical Botanical Gardens on the island of Kaua'i.

Apparently, the Polynesians gave up the cultivation of rice (from their native Taiwan) and cultivated the breadfruit instead wherever it grew.

The NTBG is trialing the use of breadfruit to combat starvation in tropical nations[2]: hopefully, in the event of a Bananapocalypse, breadfruit could help alleviate the loss.

We get a lot of these in AI research. When your math is a hideous snarl of abstract algebra and graph structures and your code includes a novel 3d dynamics engine and custom collision detection, it's exhilarating to see your simulated robot so much as twitch a finger in the right direction.
Confirmed with 2.3 and 1.9+. We had a ton of encoding issues with that combination. We had to ensure every single thing was encoded properly.

How so? I'm actually surprised how little they seem to have reacted to the competitive pressure of Android than pursuing their agenda at their own pace.
A critical skill for a startup incubator is reaching all the people who could succeed and make them a ton of money.

That includes openly and directly addressing mis-impressions the talent pool may have of who the incubator is looking for.
Ask HN: What Free IDE do you use for WebDev?
Sublimetext is not free and not opensource. Is there any opensource IDE for Linux or Windows 7(efficient IDE like sublimetext)?

Thanks! :)
Mainly due to string encoding. For something like Github, mistakes there could be disastrous. With all of the special characters and user input there are bound to be wild edge cases.
People need to stop buying terrible phones. Consumers keep rewarding companies who don't keep up with their promises and thus no one ends up giving a crap.

In my opinion if you're not going to buy a Nexus device or a Moto E/G/X then you might as well buy Apple. The Android One program will hopefully add more to that.
both are chrome. just different versions.

google ridicules microsoft with IE6, and the first offline platform they release they made the exact same mistake!

bundle a integrated browser just so the use cant uninstall... and decide to not patch it.
Tim Harford, and the perils of big data
Comments like this one make me have no desire to even attempt to "fit".
"90% of phones" and "20% of Web traffic" are two different claims; there is no correction.
An important lesson I learned while working as a sysadmin was that when you're making operational changes, you do one thing at a time.

Let's say you need to set up a replicated database with failover and monitoring.

First you set up the database (and make sure it works).

Then you set up monitoring (and make sure it works, too).

Followed by replication (which should also work).

And finally, automatic failover (there's a pattern here...)

This sounds obvious, but I've worked with developers that, when given this task, tried to set up the entire thing in one shot. It took them over a month to wrap up, and they didn't have time to properly test it, because they bit off too much in one go.

The same goes for migrations. You work along an incremental plan to move from Point A to Point B, where at every step of the way, the set of things you need to change is small enough to manage, and you have the option of rolling back.

I can't imagine that Github has a tiny codebase, so I could totally believe six months for a zero-downtime Rails 2.x -> 3.0 migration. The next big step (3.0 -> 3.2) will be easier from what they learned in the first step, as will the step after that (my guess is 3.2 -> 4.0).
Only temporary and easy to remove. It would be tricky if entire classes/objects/abstractions were missing entirely. This would require essentially reimplementing that part of the code.

For other Rails version changes, for instance, the removal of RJS as a default component in rails 3.1 could require that you re-architect certain user flows or pages in your app.
"deprecated" while there are still millions of consumers whose products only run 2.3.3 with enough memory for aosp browser (which they cant even uninstall)

GrowthHackers is more marketing focused, while HN is more engineering focused. While I do see overlap, I believe both serve largely separate communities. What's really impressive is someone who can hold a conversation in both communities.

I think the mistake was to try to stay on. Then you have the 'old captain' and the 'new captain' on the ship at the same time and that is a recipe for trouble if the desire for another CEO did not come from the old CEO.

That's a thing I've seen play out in two other spots and in both cases it ended more or less like it did here (only substantially quicker).

I fully agree with you on the 20/200 matter. I'm like that myself (and even the '20' is not my ambition but more along the lines of 'somebody has to do it').
I have a friend who is a YC alum and he is definitely hispanic. Not going to call him out, and of course that is only one person, but I don't feel that being a minority is going to hurt you. YC has made a lot of effort to address diversity: http://blog.ycombinator.com/diversity-and-startups
Looked into it, the domain that is available has an "s" at the end.
An Index Fund on the Dow Jones at pretty much any point in the past 5 years would have delivered ~10% returns.

As noted in other comments, doesn't mean it will last forever (although I'm seeing a lot of economic analysis that supports it over the medium term). And it's not where I'm investing, but then I'm the entrepreneurial control guy not a passive investor like the OP.
Same here! So frustrating.
Edit: ok got it.. just follow the animation exactly but just click once at each point, don't drag a line out..
This is why you don't give up control of your company no matter how nice things seem. Founders should maintain absolute control over 3 out of 5 board seats. The Parker rule.

Whatever his flaws the company wouldn't exist without him. His investors knew who he was before they invested. They should be forced to negotiate. They should not be able to fire him.

A16Z is an investor in 500px. They claim to support founders so I'm sure they will make a public statement explaining how they tried to help this guy but were outvoted.
The notebook is excellent for its intended domain, which is scientific exploration. It is very good to be able to create definitions and change data, having the results immediately visible. Notebooks can also be saved in its current state and exported to other formats.
Ah. Thank you for pointing that out. I completely missed it. I will delete my comment.

Most virtualization servers are great big chunks of C and C++ running as root with a bunch of crazy optimizations for benchmarks. They get some help from the ISA, but... stuff happens.

Ask HN: Which Registrar Has the Best Domain Management Tools?
If you own a lot of web domain names, with various expiration dates, it can become challenging to manage them all. Let's temporarily forget about cost, sleaze factor, and abundance of up-sells. Which registrar makes it the easiest to manage your domains? (search / sort by various criteria, see domains expiring soon, renew easily, transfer away easily if necessary, etc.)
It's only been a few years. Not everyone can churn out smash hits like clockwork, even if they are really talented.

If he ever does create another big game, I'd expect it would be many years down the road, after he's toyed with a lot of ideas and had more than a few false starts.
Is a serious question? I cannot even begin to guess how it's even close to relevant.
I would have loved to have something like this in school. I ended up paying for mathematica while working on my degree. I think IPython/Sage connected to an open-source version of Wolfram Alpha would be a Killer app. Any chance Julia would be integrated at some point?
Why admission to Ivy League colleges isn't based purely on academic merit
Yes, I do think so. Then I could keep thinking about the "business problem" instead of googling for half an hour because I can't believe there is no one reuses a stack in Go.

Also, it could be something much more complicated than a stack, like the data structures in the STL... but that point has already been made elsewhere.
2106 yen in a bookstore in Tokyo, not including tax. A little less than 20 USD.
Yes. Maybe this is why we are not in marketing :)
There are some problems where you just have to write a lot of groundwork before you can see anything for it and pushing something out fast wouldn't really have any benefit.
Overlong shifts are currently not handled correctly, yes, but they will not be undefined behaviour; they will possibly be implementation-defined but will not lead to memory unsafety.

> use-after-move [...] ---references outlasting their owner---

Not really, e.g.

std::unique_ptr<int> x(1);
foo(std::move(x));
std::cout << *x; // undefined behaviour

Unless you mean something other than `&` references.

> Honestly, I loved the idea of Rust. I was sold a memory-safe C++, and that sounded awesome. But what I got instead was an ML with some low-level extensions; it felt like an enormous bait-and-switch, as nobody is interested in yet-another-functional-language.

Something in this sentence has to be wrong, since people are clearly interested in Rust: either people are interested in YAFL or Rust isn't what you seem to think it is.

Anyway, that just sounds like a 'problem' with your background/expectations and/or whoever sold it to you. Rust is a C++ competitor (i.e. targets the similar low-level space) but it is not definitely trying to just be a C++ rewrite fixing the holes. I don't think there's any official marketing implying the latter.

First: if you're building sites that people are using, you are officially a "junior web developer". That's especially true if you're deploying and supporting those sites.

Second: PDX.rb is a friendly, knowledgeable group. Find them on calagator.org and go to some meetups. They'll absolutely help.

I don't really do Ruby or Rails any more so I can't offer much more concrete help than that, but welcome to Portland regardless.
No kidding. As an API provider, Mojang is pretty terrible.
Project Hieroglyph – working toward optimistic sci-fi
No offense, you really seem to make a fundamentally false assumption about what your money has to tell about your inner process.

But personalities aside, lets talk mass markets.

Think of a random teenage girl who shopped for Alphabits 4 hours ago, twitted of #mileycirus 40 minutes ago, then started typing a private Facebook message to that bully from school, then took a monthly dose of her brother's ADHD prescription and went postal 2 hours later with the largest shotgun from her dad's attic.

Or maybe she didn't?

As of two hours ago, she still had a chance to become the next Rosa Parks. You don't know that. I don't know that. Mark Zuckerberg knows. Three years later, he wants to sell her profile to her first five potential employers for ten US cents apiece, and probably ruin her life forever.

(I might be exaggerating just a bit for the sake of argument, but God knows how many Stanford graduates on Facebook payroll are looking for much more subtle patterns in her data as I write this)

Good news is that Facebook is doomed. Ephemeral is the new king, guaranteed crypto ephemeral is the next one. No one wants to talk to Zuck when one wants to talk to his girlfriend.

Zuck is simply out of fashion. Somehow, teenagers know better than we do.
Well, that's how they learn. That's probably how you yourself learned it.

Kids need to be able to tinker with computers, and that includes both downloading malware and cleaning the machine including possibly reinstalling it from the ground up. That's how people grow their digital immune system that helps them navigate technology landscape safely.

Constantly fixing everything for our kids will lead to another generation of computer illiterates. This article covers this topic pretty well:

> This annoyed me a little bit. A check engine light is the perfect component for what it does. If it's on it means that something may be seriously wrong and that you're probably too stupid or ill-equipped to fix it.

> If it was something simple, easily detectable and fixable it would have its own light, ie the door is open, you're running out of gas.

I've been in new vehicles with a single light for "low tire pressure". But it wouldn't tell you which tire. Sure, I can discover this by manually reading the pressure on all the tires, but the system has to already know this information. It's just incapable of displaying it.

How the airlines could confront this is by not reliably stopping in the intermediate cities. That is to say, multi-leg flights should sometimes not stop in those some of the intermediate destinations, so that passengers who want to get off there using a cheaper ticket face a gamble: the risk of ending up in the wrong city, wasting time and money to get where they really want. Yes, the plane has to pick up people from those place, but the logistics of that could be worked in with the uncertainty so those people are taken care of. Some other plane grabs them in that case or whatever. Perhaps another airline's plane with some kind of sharing plan.

Say two airlines N and M have flights from A to D. One airline stops over at B, and the other at C. They could enter into a flight sharing agreement so that they pick up each other's passengers at B and C. Then it is not known whether any given N or M flight will stop at B or whether at C. The only sure destination is D.

(Not saying I agree with this, but it's better than other tactics, like bullying customers who are only behaving rationally. "May or may not stop in Dallas": problem solved.)
I use gandi.net and am very happy.

I think that your criticism of the classifications is misguided. Certainly, depression and anxiety are different disorders, caused by different chemical mechanisms. And, bipolar is certainly different. And, I'm extremely glad that medicine has evolved and can now treat these diseases differently. With new dopamine agonists, sufferers are able to achieve normality. Unfortunately, there are a good portion of the population that suffer from this disease and others. And, 'categorizing' it helps both in diagnosis and treatment.

Biploar is different from depression, which is generally treated with SSRIs. I'm neither a chemist, or a molecular biologist, but I infer, from reading, that depression is caused by different chemistry, related to different parts of the brain. Depression and bipolar may have similar symptoms, at times, but the biological origins seem to be unrelated.

There's a strong body of evidence that bipolar is correlated with schizophrenia, autism, and ADHD. Again, this isn't my field, but each of these diseases relate to the dopamine pathways. And, there are quite a lot of genes that take part in and/or affect tyrosine-dopamine production. I also infer that the gradients of these diseases are caused by combinations of genes, in each individual. So, it makes sense that biploar I is treated differently than bipolar II. Once scientists have better understandings of genetics, treatments will become more granular and targeted. But, currently, if you're a sufferer, you must take a cocktail of drugs, in different doses, until you get the 'right one'. It's not the best way, but it's the best that we have today.

As an aside, I find the original article very surprising because it's widely known that multiple genes and SNPs are involved in incurring risks for developing schizophrenia (and bipolar and ADHD). To me, who continues to research the topic, I had just assumed that the results of the research were true. But, I'm glad that they were able to take controlled studies to help verify something that is deductive.

Here's a thought experiment: ask Google if they would do it for free!

I'd bet that Google would jump on it, just because. Okay, so they'd serve ads for bail bondsmen and for ambulance chasers with every page view, but at least we'd have the data.
Just incase anyone in the TO tech scene thinks I (Zach Aysan) wrote this, since it was posted at the exact same time as my comment below, I feel like I should say explicitly that this comment does not come from me and I do not know who wrote it.

So from my reading, the arguments against meritocracy in the Ivies are: Naked racism (both negative and positive), greed (although Harvard for example has no need for money these days), and nepotism.

Got it.
That's true, and that's why I said YC may very well want to highlight such founders from disadvantaged backgrounds, if only for their own benefit.

However, I'm assuming that the YC partners are not going to be taking advice from me just because I post on Hacker News. People thinking of applying to YC might (hell, I might). They can control their actions, they can't control YC's actions. Why not focus on what you can control? That's another critical startup skill.

I don't see why shiny progress should be held up because you can't be arsed keeping up with new generations of tech. If you don't like it, go install a rom and some of the many many many alternate applications which keep sizes small.

Mobile phones began, much like desktops began, extremely limited. We are simply seeing the same thing happen, we're now getting up to sizes of around 32 gb, yes, it happened much faster this time, and that may be why many feel the pinch much more - I'm sorry for that - however it is the price to pay for being an early adopter like yourself.

Yet thankfully,it has also now reached a level where it is now almost impossible to fill with application data. Storage and processing may continue to increase but I highly doubt you will feel quite the same pain of running low on space with nothing but chrome and facebook installed.
There aren't any plans at the moment. We've struggled with this problem before, and wrote something similar with https://github.com/khan/KAS/ but we've never worked at doing something inline. We use MathQuill in a couple places, which does the input decently (writing works, but typing something like x^2_2 gives you x^{2_2} not x^2_2), but the output doesn't look great. It's hard to do what the user wants, have clickable bits, and still have good looking output.
