I like programming in Perl and C. I know Java and PHP too (I'm a MediaWiki developer), but I can't really say I like them. I keep meaning to learn Python some day, but never seem to get around to it.
I'm working on a Ph.D. in biomathematics. I also like programming puzzles and cryptography.
Please consider any (original) code I post to Stack Overflow (and other Stack Exchange sites) to be released under CC-Zero unless stated otherwise. You may do whatever you want with it and don't have to credit me in any way, although of course that would be nice.

How can I speed up this design? @bear96: 100s of images doesn't sound that bad, even for a phone, unless those images are huge. To minimize overhead, thedeadlybutter's suggestion of using a sprite sheet sounds like a good idea. |

How can I implement gravity? You can fix most of the issues with Euler integration simply by replacing position += velocity * timestep above with position += (velocity - acceleration * timestep / 2) * timestep (where velocity - acceleration * timestep / 2 is simply the average of the old and new velocities). In particular, this integrator gives exact results if acceleration is constant, as it typically is for gravity. For better accuracy under varying acceleration, you can add a similar correction to the velocity update to get velocity Verlet integration. |

random spike in delta time OK, obvious question: glfwGetTime() returns a double -- are you sure your time variables are doubles and not ints? |

How does a one-man developer do its games' sounds? @PeterTaylor: One should be careful, though, since while a lot of famous classical compositions are in the public domain, a lot are not (yet). Want to use something from Orff's Carmina Burana? Sorry, the lyrics are in the public domain (dating from the 12th century), but the music (AFAICT) is not. Ditto for most of the composers in this list. |

Does an inventory limit in an MMORPG make sense? I'm somewhat surprised nobody's linked to this Penny Arcade strip yet. |
