I can't count the number of times I've had to re-kick a build because a timing-dependent test like that failed (busy build server, inopportunely timed gc, etc). One of my top programming annoyances.

The equivalent errors in dynamically typed languages don't lead to critical security vulnerabilities like they do in C. You get a nice exception and a clean crash, not a hook to grab root.

FB doesn't want real names and addresses so they can start sending out snailmail spam, they want them so that they can start user matching with advertising partners' CRM databases.

Using lambdas in Java 8 looks pretty much exactly like your example. The line you quote from the article is about a proposed way of declaring lambda types, where instead of private Foo MyMethod(string str, Func<Bar, string, int&#6

Are you fucking serious? Goebbels used propaganda to further the cause of genocide. Don Stewart thinks Haskell is pretty cool and shares that with the world. The fact that you think the two are even slightly comparable...

"Goebbels of Haskell"? What the hell is wrong with you? Assholes like you are why this site is going down the toilet.

For me it's as simple as knowing a product I like is not going to be developed anymore, and having a complete lack of faith in Google to use them to turn out anything near as good.

The most common derivation of Black-Scholes absolutely does assume a standard normal distribution. There are other models that don't (i.e., Mandelbrot tried to get people to use Levy distributions, and a lot of newer models are built aroun

If you ignore the absurdly stupid title, this is actually worth a quick read. It's excerpts from interviews with Myron Scholes and Ian Stewart woven into an oversimplified but not completely awful overview of Black-Scholes and its impact.

This is a great series so far, but I think some people are taking it too seriously. This is roughly the equivalent of giving you a good tutorial about how a short map-reduce implementation works and then asking you to agree that Hadoop is

The whole point of this thread is that "better" isn't sufficient, either. If people are happy where they are, the only way "the same thing but better" wins is if it's so much better that it covers the perceived switching cost. There aren'

Okay, so make a better product. Just don't market it as 'the same thing but better', market it as 'different and better'. That's the point.

The entrenched winner in the late 90s right before Apple's resurgence was Wintel - cheap and everywhere. What does Apple do to compete? The name of the campaign was literally what the parent comment says a company needs to do - "Think Dif

I think you're missing the point of the question. I'm not asking how you scale in general, I'm asking whether your replication scheme is only for failover or if it contributes to your scaling story - i.e., if a given key goes hot, does eve

I'm reading through the paper, and I'm curious if I understand the implications of key subspacing and value dependent chaining correctly - do all reads and writes for a given key get forced to a single node? I understand how the replicatio

You don't need a map, just a reduce (foldl, really). Using underscore, no double calculation: _.reduce(arr, function(p1, p2) { var len = p2.firstName.length + p2.lastName.length; return (len > p1[1]) ? [p2, len] :

For anyone else who hits this, this should get you going: http://loopkid.net/articles/2011/09/20/ssl-certificate-error... Basically, you need to get the right certs and then tell wget to use them.

Not really, but it's not important either way.

Matlab, Octave, Mathematica, and other mathematical programming environments use 1-based indexing, it's a well-established norm for the domain.

Just spent the last hour reading through the docs and playing around with it. This is some damn sexy stuff. It's been a long time since I've been this excited by a language.

Even for financial reporting, this is an egregiously awful bit of journalism. Once upon a time it was both an honor and a privilege to go public. A company worked tirelessly for years just to get to that point and it leapt at the opportuni

The biggest problem with this rant is that it's attacking a strawman version of Khan Academy, pretending that it's only a website with some videos and exercises. It's not. KA is actively developing and testing an in-school curriculum that

You can still assign these values to semantically-named variables where appropriate, with the bonus of not having to monkey-patch ints just to define a few dozen constants. It's benign, boring utility code, I just don't get what's offensive

by jfager 15y ago
Just by the mere fact that these are constants documented to be in seconds, it's clear that they shouldn't be used for sensitive or precise time calculations. If you're at the point where you don't realize this, you probably aren't going t

I see absolutely nothing wrong with this. It replaces a slow way to write human-readable intervals with a fast way. How is that a bad thing?

That's only true for people who don't follow the solar industry. They got their loan in March 2009 ( http://cleantechnica.com/2009/03/21/fremonts-solyndra-wins-f... ), filed for IPO in December ( http://gigaom.com/cleantech/solar-tube-make

Solyndra failed because its secret-sauce technology couldn't get cheap enough fast enough compared to the plummeting cost of photovoltaics. So it fits pretty well.

This looks great. One thing that's a little annoying is how the vertical axis automatically scales to the range of the data. It makes it hard to compare peaks that don't occur within the same view range.
