I'm able to access a, since b is below a on the stack. No, it's not! You have no guarantee in what order the compiler allocates temporary variables on the stack, and even whether it does so at al...

Writing to the file on the HD is your massive bottleneck no matter how many threads you throw around. The limit is the physical memory access speed, not processing power. And since it is such a bot...
I've just dived into pygame and written a little game in it, of which I'd like a review (it's my first try of pygame). However I'm not sure if it is a good fit for the site, and if so, how exactly ...
This is both by design. Lundin's example is an answer link, which intentionally puts the selected answer at the top of the answer list. Because we only have two answers here, this isn't as intuiti...
I was searching further why it's not working properly. Then I created a CSS file. Linked that CSS to XML using the following command. <?xml-stylesheet type="text/css" href="test.css"?> Th...
The main problem with using floating point is that the typical floating point type is binary floating point. But in binary floating point, most decimal fractions cannot be represented exactly. That...
