The biggest barrier for me going to sleep at a reasonable hour is the required ritual just before going to bed. Brushing my teeth, flossing, taking a shower, changing into bed clothes. From now on, I'm going to try this: - Brush my teeth, f

Please please please do not make the API dependent on HTTP method verbs. This completely breaks JavaScript apps[1] and it's an arbitrary constraint that does not benefit anything except REST zealotry. [1] For example, cross-domain JavaScrip

I liked this one more: “Zuck [...] went ahead and built Facebook, and just to prove how useless everything we teach about efficiency and careful software design in CS161 really is, he implemented it in PHP.”

As far as I can tell, isogenicengine is not published. There's a beta signup, that's about it.

True story. Wasn't aware of Benchmark.js, looks good! Anyone want to fork n' port? :)

You're right, I should be running each test at least a few times and taking the average. I found that the results vary a few percent here and there, but the drastic difference between the different datastructures is always consistent and vi

Almost all of those methods use approximately the same amount of memory, though the performance varies drastically. The key is that few people know what's actually going on underneath the JavaScript interpreter engine. In some cases it coul

I was trying to benchmark the actual speed of updating the canvas, in hopes that it was doing something clever behind the scenes. I can see that it's not a fair comparison, but a fair comparison is completely redundant with grid_array_1d (e

Ah, you're right about that! I'll fix it when I have a chance, though it wont affect the performance. You're welcome to clone the repo, make changes, and run the tests yourself (just open index.html in a browser). I was surprised too, but m

getImageData returns an array equivalent to grid_1d_array. The computation required to translate the 2d position (in this case 3d position as there's 4 slots per index) is what killed the performance of grid_1d_array. Also I don't see how i

I've been meaning to try WebGL. Any interest in contributing an example into structs.js? Edit: Or I guess it would need to go into a separate <script> block, could make a structs_webgl.js one.

That's one of the ones I tried, but I needed some tests to create new objects, and others to reuse the same object which was already created previously, and I wanted to compare the numbers together rather than in isolation. To use jsperf, I

I considered this but there weren't any existing services that did this and allowed me to make the type of tests I needed to make (and I didn't want to spend unnecessary time building one). I also ran the benchmarks on Firefox and though th

Fantastic. Signed in using Twitter OAuth, imported my Delicious backup, completely painless. Now if you release an API and people make awesome Chrome/Firefox extensions, you're on your way to sell this beauty to Yahoo! :P Edit: Looks like t

A rounding error that causes a fast-paced Javascript game to crawl to a laggy stutter when repeated all over the place. Regardless, the Closure Compiler (that the Closure Library is made to be used for) fixes this common case. Another examp

That sounds amazing. Side note as someone who grew up in Toronto and lived in the downtown core for several years: A studio would go for under $1200/mo. You can get a pretty swanky 1bdrm for under $1400/mo. Though I have no doubt one could

I'm not convinced that great designers do things completely instinctively as they go along but fact of the matter is it does take a lot of time (especially if you're spending 90% of your time learning how to do everything), and I have no

The cliff is incentive to stay that first full year. The gradual vesting of the rest of the equity is incentive to stay past it. If people are leaving immediately after the first cliff, then the proportions might need to be adjusted. Perhap

Pylons is still a great framework, and will be for the foreseeable future (a few years?). Just because it matured and reached its end-of-enhancements life, doesn't mean it's not useful. It will take a while for Pyramid to mature to this lev

Eh, it's a good market to take those kinds of risks right now. Everyone is hiring, no one wants to be hired as they're doing their own startup, it's ridiculously easy to get a job—especially at startups.
