Upgrading to jQuery 1.9.x

Today it snowed. It started before we awoke and pretty much kept at it all day. Hence it was a day to do some work inside, and what better task than to clean up my blog? First port of call, and a major one at that, was to upgrade to jQuery 1.9. Before you say, so what, just change the version number in the <script> tag, consider this. jQuery 1.9 removes several APIs that “behaved inconsistently or inefficiently in the past” ( here ), ones that have been deprecated for a while. So, replacing...

PCPlus 319: Recommendation algorithms explained

For the March 2012 issue, I wrote about a new subject for me, and one that I hadn’t really seen much discussion of elsewhere: recommendation algorithms. Whenever you go to Amazon to buy something, there on the front page is a set of items that you might want to purchase.

More script kiddie douchebaggery

A little while ago I mentioned some work I’d been doing with regard to 404 error processing with this blog’s engine.

PCPlus 318: The physics of Angry Birds

Without a doubt, this was a fun article to write. Not only was there much research done in order to understand the physics of the game (that is, how gravity worked in the game, how collisions were mimicked, and so on), but I also had to play it. A lot. Can you say that you claimed $0.99 on your taxes because buying the game needed to be offset against the income from the article? I thought not. Anyway, on to the gist of the article. I cover three main topics: the parabolic flight of the red bird...
