US Court/Justice system - so pathetically amateurish.
The EU bangs Microsoft and Intel for Euros-By-The-Billion (the new plan to help the Greek Economy).
I believe it's time for revolution: turn-about is fair play.

During TechEd 2012, Telerik announced their first commercial library for building Windows 8 Metro applications. This control library is a set of controls for XAML and HTML apps. User can chose the language of their own choice and deliver a high end Windows 8 enterprise and consumer applications using these controls.
In this blog post, I will describe more about the controls and guide you to kick start with your Metro application development using the Telerik RadControls. The controls set is neither yet released nor available publicly to download. In case you want a special early adopter access, this blog post will help you to get one too.

I invented/discovered/came-upon "Inverse Fizzbuzz" while mucking about with Scala & Partial Functions. While Fizzbuzz answers the question "Can Shipper code?", Inverse Fizzbuzz tells you "How well does Shipper code?" Given a list of strings, what's the nerdiest thing you can do?

Microbenchmarks are evil. Ya, I said it. Folks spend hours in tight loops measuring things trying to find out the "best way" to do something and forget that while they are changing 5ms between two techniques they've missed the 300ms Database Call or the looming N+1 selects issue that has their ORM quietly making even more database calls. Fun with Microbenchmarks!

Really? I mean, really?
In my experience when anyone dares to wonder aloud if a pice of code could be done more efficiently, There's a barrage of an out-of-context "Premature Optimization is the Root of All Evil!" raining down on a poor guy wanting to learn.
They always claim "folks spend hours squeezing useless microseconds." Without even as much as anecdotical evidence. Optimization is the new goto.*
I think this mantra is an excuse to ignore performance questions - because the "first make it run, then make it fast" is based on an assumption that fails on modern hardware: that performance problems are isolated. Wondering if something can be made faster is the best way to demystify the compiler, especially for people who never used low-level languages.
[edit] Oh wait, Scott just had to pull a "I'm not a witch" defense before doing some microoptimizations.
*) which is appropriate only because of the original source of the quote.

There was a time where you could significantly improve the memcpy of the standard libraries. More than one, actually - and sometimes it even did matter.
With the move towards more-RISCiesque instruction timings, looping and unrolling would improve over REP MOVSD especially for large blocks.
With the move to better optimizers, an inlined loop could omit alignment arithmetics, and use SIMD instructions.
So it depends when and what for that guy did it

actually slower than an unrolled loop?
I honestly don't know for todays processors, but around the early Pentiums, indeed. Some mix of branch prediction, unrolling and instruction pairing I guess. Intel and AMD were throwing their resources on the most frequent instructions, pairing and branch prediction, so the more complex ones had to take a back seat. That's what I meant with the "more RISCIeque" instruction set: improving the throughput for simple instructions.
_beauw_ wrote: By SIMD I presume you mean MMX / SSE / SSE2 / 3DNow! instructions, right?
Yes. And no, REP MOVs is not one of them, though it could be. I got out of assembly stuff at the time SSE was gaining wide support, but - again, IIRC - using MMX to load and store 64 bits at once was like magic.
My point being that if the guy you know is *ahem* not 15 anymore, and he isn't doing that now without good reason, he's not as crazy as it might sound today.
And some habits die hard. I only recently gave up my "file header decorations" that are clearly from the time before source control.

Pretty soon we'll have people writing video encoders in C# (with LINQ of course), and much bawwwing about how it can't possibly be made any faster without violating the religion of the authors will ensue when people start complaining that it's two orders of magnitude slower than x264.
Or has this already happened?
Huh, optimize cash[sic] usage you say? What does switching the order of these loops have to do with my financials?
What is SSE? Some sort of utility company[^]?
There's also enough wrong with his benchmark that he's ironically right about one thing: some people should not be micro-optimizing.

One of the fundamental truths of software development is that you have to write code, but one of the biggest fallacies is the idea that writing code is your job. When I first started out as a software developer, I fell into that trap - writing code is a powerful thing, its empowering, you feel like you are productive and you are accomplishing things. However, what I have learned over the years is the real truth of the matter. The truth that the job of a software developer is to write as little code as possible. Other things being equal, a simpler program is better than a more complex one.

Is sounds like you need to get a Gov't grant to investigate this most obvious of statements. Where is the  icon.
Next they will be telling us that we need to create solution!

That depends on the situation otherwise bubblesort would be the ultimate sorting algorithm. Of course software should be as simple as possible but also as complex as needed. If you need a faster, but more complex algorithm than you should follow the needs and implement it. If it isn't needed use the simplier one.
But before implementing the simplier one better ask: is the simplier one needed or can we use another tool we already have.

Ah, another opportunity to quote this, slide 25[^]:
Can code metrics predict the post release fault rates?
We thought so but...
- Most metrics increase with code size
- code size is repsonsible for all the signal

JavaScript has gone a long way since its birth in 1995. A hard way for sure, full of misunderstanding, misuse and ignorance. But times have changed, since the last five years JavaScript has been gaining more and more attention. With more attention, more developers are actually using JavaScript, using it for many different purposes and enjoying its beauty. Classical "Ugly Duckling" story, if you ask me. 10 uses for JavaScript that are different from the common "in browser" ones.

Now that you understand the basic idea behind arithmetic, let's take a look at a simple easy-to-understand example that puts into practice what we just learned... If the authors of computer programming books wrote arithmetic textbooks...

What would you say if I told you that I could put you in charge of the biggest LEGO set you have ever seen, giving you access to more than 8 trillion blocks. Oh, and you wouldn’t even have to move from your seat? Well, that’s exactly what Google has done. Play with LEGO online, then place your creation on a real Aussie landmark.

Google scientists created one of the largest neural networks for machine learning by connecting 16,000 computer processors, which they turned loose on the Internet to learn on its own. Presented with 10 million digital images found in YouTube videos, what did Google’s brain do? What millions of humans do with YouTube: looked for cats. The neural network taught itself to recognize cats, which is actually no frivolous activity. In a Big Network of Computers, Evidence of Machine Learning

We present the first large-scale analysis of hardware failure rates on a million consumer PCs. We find that many failures are neither transient nor independent. Instead, a large portion of hardware induced failures are recurrent... Among our many results, we find that CPU fault rates are correlated with the number of cycles executed, underclocked machines are significantly more reliable than machines running at their rated speed, and laptops are more reliable than desktops. Blue survey of death.

I love scripting and am quite frustrated by what apps don’t support scripting (or support it poorly). But when I go through my script folder I find that I really don’t have that many scripts. If a big scripting proponent like me doesn’t use scripting nearly as much as he thought what does that say about 90% of people? AppleScript is (almost) dead. Will anyone (except uberdorks) care?

Are you part of a software development team that's recently moved to GitHub? Where some team members are excited to use git for source control but you're more comfortable with Subversion? The good news is that you can all use the tools you already enjoy - GitHub repositories can be accessed from both Git and Subversion (SVN) clients. Now you can commit without making a commitment.
