pngquant is great. I make an iPhone app that displays transit maps. Transit maps are ideal candidates for quantization (limited color range, large blocks of color that are perfect for RLE) and I saved a lot of file size by quantizing the ma

Fatal flaw in this plan: unions. New York has already tried to switch to driverless subways, but progress is slow due to constant union interference.

Windows 1.01 feels much closer to Mac Classic than Windows 3.1 does. (Button appearance, close button on left, menus must be held down to stay open, "Get Info" instead of "Properties".)

BART jobs are quite supply constrained. Sure, union jobs are great if you can get one, but there aren't many to go around. Plus, who would really enjoy working in a workplace where everyone doesn't care? I couldn't stand it e

I took Brian Kernighan's class when I studied at Princeton. As part of the class I developed www.itrans.info which set me on my way to being an independent app developer. I'm enormously grateful for his class, his involvement with students

Nice idea, but the sample code they show in the screenshot uses "FALSE" instead of NO (the Obj-C standard boolean literal). I'm not sure how they did that (#define?) but stay far, far away. Imagine if you opened up a Ruby codebase and found

For webapps, I agree. There is no progression of state in a webapp's "controller" object: it's one shot and done. For native apps in frameworks like Cocoa Touch of course it's an entirely different ballgame. A view controller has quite a bi
