As much time as is necessary for "Website Building".

If you bring in your Quality (or "testing") people after the inception - you put them in a position of disadvantage (always catching up, and always behind) for the rest of the project; and if you do not empower them sufficiently you are just paying lip service to quality and crossing a line of the list -- and are very likely to endup like this project did.
These are WebSockets, not typical HTTP requests. Connections/sec is less important because they will be long-running. The client is not continually reconnecting as they do with an HTTP request.

What matters most is total connection count, which appears to be very high. At 6,000 open connections on a free dyno, that is better than Pusher's $199/mo plan: http://pusher.com/pricing

I think what needs to be done after this is checking how much data can be sent per second. Both in terms of raw bandwidth and messages/sec.

AI Company Claims to Have Broken the Internet's Favorite Protection System
Diversity of implementations on the web is vital for continued innovation. Though it's less important that IE stick with the Trident engine now that Blink and WebKit 2 have diverged, we should celebrate progress and encourage participation in the standards process - things IE has gotten a lot better about especially in the last two iterations.

> has been and continues to be hostile to the web

I'm going to have to dispute "continues to be": http://caniuse.com/#compare=ie+11,firefox+25,chrome+31

You have to scroll down quite a ways before you find feature differences between the browsers, and it's not quite clear which (except maybe Chrome) is the best. If we remove feature drafts, it's a good deal closer.

Now, regarding has been: http://caniuse.com/#compare=ie+6,ie+7,ie+8,ie+11

Well, there's no contest there. IE8 being the last supported browser on XP is a harsh reality for web developers. :(
The technical details of how this series of exploits were identified, much less applied, is staggeringly complex. I love speed and/or glitch runs and I can't imagine this one being dethroned anytime soon.

I'd think gene therapies for people who discover that they're predisposed to diseases after DNA screening would have greater demand. There's a lot more people currently alive than being born. Each generation cares about its own survival more than future ones.

> They looked at what's probably the most meaningful ratio...

Says who? While price-to-sales can be a very useful metric, I don't know any experienced market participant who invests or trades off of fundamentals who would argue absolutely that price-to-sales is the most meaningful ratio off of which to determine whether a company is undervalued, overvalued or fairly valued.

And using the median value of this ratio at IPO alone with a small subset of companies in an effort to argue for or against the notion that there's a "bubble"? That's simply not credible.

For what it's worth, if you do want to look at price-to-sales, and in a more meaningful context, it's worth considering that the median price/sales ratio in the US markets is at a record high and exceeds the mean by a near record margin as well[1].

So, wave a wand and say "a robot will do it". That doesn't count as "A printer that can print a 2500 sq ft house".

Even imagine the robot exists: how exactly does it just 'plug in' the plumbinb and electrical systems? Currently it takes a person to scramble all over the house, drilling and fitting and connecting.

There is nothing being solved here. Just a blue-sky story about an imaginary printer.

I cannot see how this would not lead to a very disproportional distribution of welfare. Very few people, I guess, would rather give their money to rehabilitated murderers or sex offenders than to orphans or abused women for example.
Except I didn't dismiss the idea. I'll restate, "Given the urgency and reward behind efforts around gaining advantages of market trades, I can assure you if it's technically possible, they've done it and perhaps we don't know about it."

Notice I did NOT state the corollary, "I don't see trading boats in the Pacific, so it's not possible to do.". I suppose that could be accidently inferred from my statement, but that was not my intent.
Another class of these optimizations that are even harder (for me) to spot exploit matrix decompositions, multiplications, etc. If you can manage to convert your problem into some linear algebra system, a fast BLAS can do wonders. And then selectively using some BLAS result (that has side-effects as the article defines them) is even harder.

Unfortunately, it's often just as hard to distinguish such code from magic when reading it.

Lesson to learn for an Entrepreneur

Thanks. I hope you'll also update the landing page of the challenge.

A little more feedback, which I hope you'll take as constructive:

As I said above, there's quite a difference between "if you do this, you'll win this" and "if you're one of the first 11 people in the United States to do this, you'll win this."

As I see it, if I have any chance of winning the prize, I've got to drop everything right now and scramble to complete the challenge, and even then, who knows how many other people are doing the same thing?

So, my incentive has just dropped from, "This is exciting! I have a decent shot at getting pizza!" to "It's extremely unlikely that I'll win. Why bother?"

I would therefore suggest that you look for ways to increase the value proposition to developers. I'm not saying you have to spend millions -- but maybe find some creative ways to reward developers outside of the first 11, such as by featuring some of the success stories on your blog.

Is it really a bad thing that software targeted at pros isn't ideal for people who aren't pros? It seems a bit like complaining that your oven doesn't remove screws very well.
yep! that's how good useful open-source code (especially APIs) are built! I mean dont u want people to actually USE what u took time and effort to write? You may not have written it for money, or to make a business, but you would want people using it. So when you code AFTER knowing what people need, the feeling is way more awesome! i mean think about it, u wanna make something really cool that no one uses? or something everyone agrees on is super cool, and would love to actually use?

I actually spent nearly an year writing a rather powerful and challenging mathmatical reasoning engine (heck it can not only solve but LEARN mathematics!) but i had no users in mind. So i could never explain to people why anyone wud want to use it. and that didnt really feel that good

"Froth" as in lots of bubbles? One little bubble collapsing wouldn't necessarily blow out the rest, unlike a singular bubble.

Or "Froth" as in "frothing at the mouth" (from insanity and/or rabies)? Given the silliness, this is equally applicable.

From having worked on a trading system in the late 80s, I know that investors (and traders) at the retail level work at a gut level and would see market moves very shortly after news items would tick across on the Reuters feed. I would argue that this article is intended to be like spraying valium into the zeitgeist for the inevitable collapse. If they can grab mindshare with this "foam" concept, they may very well be able to isolate failed IPOs to companies (without real profit) in limited segments.

For those who haven't seen it, I highly recommend one of the "original" speedruns - Quake Done Quick (on Nightmare, naturally). It's less about glitches and more about playing extremely well. If you have ever played a fast-paced FPS, you'll appreciate it.

Lots of reasons to leave randomness in, from a societal viewpoint. But nobody will stand up and say "screw over my kid so society benefits". We're all mostly selfish, exquisitely selfish when it comes to kids, we will all want our child to be the one that is guaranteed to come out useful and productive.
Another glitch that was found relatively recently (not shown in linked run):

http://www.youtube.com/watch?v=7mp0uHr2X6U&t=19m20s

A more complete explanation of the glitch occurs earlier in the video, but he explains the basics of it after he performs the glitch (unfortunately dying in the process). Apparently three different exploiters found three exploits that, when combined, enabled this glitch. Quite fascinating.

I had a great question once that didn't show my skills explicitly, but showed my reasoning skills.

I have nearly 10 years experience with international payments to and from Brazil. And although most times, it's as simple as you said, when it comes for largers amounts (i.e. USD 5K+) it is indeed a hassle.

Yes, I'm Brazilian but I do not hate the fact I'm one. I just don't have pointless and blinding patriotic feelings.
Go see the world, expand your horizons, then let me know if you still think that Brazil is really as "maravilhoso" as you like to think.

Regarding the stereotypes, I had made it clear that those points where "not so serious", but since you seem to have taken them serious:
Yes, some Brazilians are too touchy-feely and that's not a stereotype, that's a fact.
Some people appreciate that type of personality, others don't.

Mavericks' SMB2 problem and fixes
I meant to thank you for sharing this. I'd been researching protein powders and found that many reviews were kinda iffy on most (and I'm not personally fond of vanilla, blech). It's good to see recommendations from someone else with similar eating patterns (i.e. getting sick of things relatively quickly); I find that recommendations based on similar behaviors tend to match my own preferences more closely.

Or it's a placebo effect. Who knows?

If you're applying for an IT job, I ask if you have any personal projects in scope of the work you're looking to do that you're proud of and ask you to describe them. This is where I can typically assess someone's passion for their skills, or if they're just looking to show up and collect a check.
What are the basic requirements for Microsoft web developers
For me this image shows why there is something deeply wrong with programming at this moment in time; the fact you need to do all those assertions/logical operations in your head instead of the super computer standing in front of you (which is much faster in most those operations anyway) is painful to see. By clicking that line, the IDE should generate all that context (and graphs/charts/whatever) for you in a jiffy instead of you doing that in your head.
I know this might sound bad but I actually think the reality portrayed in Gattaca is not that bad. I mean, if you put aside the discrimination faced by that part of the population born the natural way, you have a society where almost everyone is healthy and will live longer than previously possible, and is of great contribution to the community. I think that's our future and it doesn't scare me that much, what actually scares me are the endless genetic mutations that result in a wide array of tumors and untreatable diseases.

I had to throw my hands up in frustration almost immediately. Obese people are fat because no one tells them they are fat?

Obese children are brutally savaged by other children as well as adults. Adults who creep into obesity in their later years damn well know it.

I think it's a sign of good manners that we don't go around pointing out unpleasant things about other people's bodies that they are constantly aware of. It makes people feel like shit, and it doesn't do anything positive to encourage them to fix the problem (like it's just sooo easy, anyway, Mr. skinny European)

Reminds me of this Onion video:

Anyway, I agree with a lot of the rest that was said - especially about sales tax and tipping.
Some cities are better for this than others. Unfortunately many of them were built in the automotive boom where futurists predicted compact roads would dominate the ground level and everyone else would walk underground or in sky bridges between buildings.

Maybe we'll grow into a reasonable solution for pedestrian traffic in cities, but the population distribution outside of those cities absolutely necessitate a car to get around.

The Russian counter-example may be valid. Offhand I would wonder how much of that 17 million km² is actually habitable, but even halving that still puts it on roughly equal footing with USA. Having never visited Russia I have no idea how it compares with pedestrian traffic vs vehicular, except the craziness I see on the dashcam videos that have been popping up everywhere lately.

Maybe we have a few things we could learn from them, but the point I was trying to make was that one 9.827 million km² country has to be architected rather differently from one at 84,421 km².

TDD: Writing Tests First
On topic:
Apple's support for command line utilities and the whole GPL v3 thing is becoming a serious issue.

Bash is 6 years old on the Mac. For the most part, bash 3.2 is fine, but it's at the point where I have to work with other people's bash 4.x scripts locally that no longer work. If this sorry state of command line utilities support from apple keeps up, I'm going to have to switch back to Linux soon.

A bit more on this, I actually just asked a question on stackoverflow ( http://stackoverflow.com/questions/19642059/proper-way-to-in... ) about installing bash 4.2 on Mavericks because it hasn't been working so far. If anyone has any insight on this, I'd greatly appreciate it.
People don't always know what they want. People have trouble seeing which of their needs can be feasibly addressed. People are bad at imagining how new ideas integrate with their established way of doing things. If, 10 years ago, you'd asked every current smartphone user whether they needed a multi-hundred dollar phone that does mostly the same things as their laptop, the vast majority would say no.

Hackers don't always know what people want. Hackers, having hammers, will only see the bits of problems that look most like a nail. Hackers, having hammers, will forget that other people don't like to deal with hammers. Hackers, having hammers, say things like:
"For a Linux user, you can already build [Dropbox] yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem."
(https://news.ycombinator.com/item?id=9224)

The real lesson is to integrate users in every part of development. Targeting a specific user group? Talk with them, try out products they use, and try to grok their needs, values, and relationship with technology. Trying an innovative interface? Throw together a minimal, flexible mockup (just enough to facilitate a conversation), and find out how people react.

Whether you should start with users depends highly on the product, but get users involved throughout the design process when user input is needed.
Wow. No, you're not the only one. Those are some of the worst compression artifacts I've seen in an actual image that wasn't just a compression demo that I've seen in years.

... you pick a demographic then go talk to them?

Sketch first means you're thinking about a product and hunting for a customer. Customer first means you're thinking about a problem first then building a solution.
That's true. I guess because I'm a "hacker" I just don't know how to ask those questions without involving the technical merits of the product.

I have a specific question, as I'm in this phase right now. I need to validate my product and demographic. It's a finance app targeted towards developers. I'm still working through the core feature-set (on paper, and a little code). It needs to differentiate itself in the details; the market is somewhat saturated. I also don't see how I can make a landing page without screenshots.

Now, how do I validate it without writing any code? I have already written some code because I need to make sure I could get certain info from banks. I need to make a landing page to get people to sign-up. Can I really do that without screenshots (even if it's mock-ups, I need to think about the UI a little)? I need to "sell" it on a few features; writing code has helped a ton to sift through my ideas. How do you flesh out a landing page when you just have an idea?

Obviously, I'm still learning about this.
vaguely related - i recently read margaret atwood's oryx and crake, which is another dystopian biotech future, and i rather enjoyed it. she's pretty cynical (and quite amusing at times) and while you can pick holes in many of her arguments the overall jaundiced view of stupid selfish humans screwing themselves over is pretty convincing.

(weirdly, some of what she predicted - about 10 years ago now - seems to be coming more true in software. you can't help but think of google when you read descriptions of the biotech corporations, with their compounds designed to isolate superior employees ;o).
