• What if you don't have code samples to give a prospective employer?

  - by lucks

  What do you do when you don't have any good code samples available when asked by a prospective employer? I like to consider myself a fairly capable developer but I can't share any of the software I've been writing for my company the last few years. Unfortunately, I haven't been able to find the time to put much work in my personal projects either.…

Understandably, she does not know much about coding conventions generally practiced, and hence all her programs tend to use single letter vars, mismatched spacing/indentation and the like, making it very difficult to read/debug her endeavors. My question is, is there a link/set of…

• How to program something with the expectation that it will work the first time?

  - by Peter Turner

  I had a friend in college who programmed something that worked the first time, that was pretty amazing. But as for me, I just fire up the debugger as soon as I finally get whatever I'm working on to compile - saves me time (kidding of course, I sometimes hold out a little bit of…

• NPOT texture and video memory usage

  - by Eonil

  I read in this QA that NPOT will take memory as much as next POT sized texture. It means it doesn't give any benefit than POT texture with proper management. (maybe even worse because NPOT should be slower!) Is this true? Does NPOT texture take and waste same memory…

  Sometimes I spend ridiculous amounts of time (hours) agonizing over making code "look pretty". I mean making things look symmetrical. I will actually rapidly scroll through an entire class to see if anything jumps out as not looking "pretty" or "clean". …
