2D gaming using Processing.js
We had a look at some of the basics of making a game using the Processing.js game library, so let's kick it up a notch by just getting down and making our own Super Mario game. When we're done with this part of the tutorial, we'll have a game with koopa troopers, platforms that we can jump up through but not fall down…

Terminals Are Weird
Terminals 1 are quite weird. Most modern users assume that they can just have straightfoward keybindings. Right? To bind Ctrl+i to something, they listen for Ctrl+i in their application. If they want to bind Ctrl+Shift+i to something different, they certainly can, they just listen for Ctrl+Shift+i as well. Naturally…

After it was published, Django launched a RemovingTheMagic project to address some of my criticisms (though personally I still find it unusable), web.py inspired FriendFeed’s tornado.web and Google’s gae.webapp and others (though I still prefer web.py), and this…

Planjure: A* and Dijkstra's in Om

You paint islands on a canvas and run path-planning algorithms to find the optimal path for your ship to traverse from start to finish.

See how well you know (or can anticipate) gcc's optimizer. For each question, the left box contains some code, while the right box contains code that purports to do the same thing, but that illustrates a particular optimization. Will gcc apply that optimization? Put another way, will the code on the left be as fast as…

How to become a programmer, or the art of Googling well
*Note: Please read all italicized technical words as if they were in a foreign language. The fall semester of my senior year, I was having some serious self-confidence issues. I had slowly come to …

The Case of the Modified Binaries
SUMMARY After creating and using a new exitmap module, I found downloaded binaries being patched through a Tor exit node in Russia. Tor is a wonderful tool for protecting the identity of journalists, their sources, and even regular users around the world; however, anonymity does

Docker Development Patterns
In the past I've written about my "home cloud" that used to be OpenVz containers, and how I've come to advocate rebuilding the "build server" for every build
