• How do i query to list out all commits by a user to a subversion repository?

  The title pretty much sums up my question, I would like to find all commits I have ever done to the subversion repository. Not just commits in current snapshot. More importantly, I would like to organize the file lists by the SVN comment used while committing. Thank you Edit: I am thinking maybe a python or shell script that would parse the output of svn log | grep username to extract revisions and then pipes the output to svn log -r [revision numbers go here] Maybe some scripting gurus can help me out..

• Java threads for the beginner

  - by Boba

  I've been trying to explain Java threading to a colleague who has never been exposed to multi-threaded applications, but apparently I'm not a very good teacher. Can anyone recommend a good online or offline resource that can explain threading in a simple, step-by-step manner? I know it's a complex topic, but surely there exists an article, book, or other explanation that can result in an "Aha! I get it, finally!" moment.

• Simple pathfinding?

  - by pdx

  Does anyone know if there is a simple way to do pathfinding in PHP? I basically have a list of numbers (kinda like {origin:11485,outboundDirections:"11486,11487,11488"} and {origin:11487,outboundDirections:"11485,11676,94185"} and getting from 11485 to 94185 would result in 11485>11487>94185 with ways to "exixt", and I'm trying to figure out how to do this (it doesn't really have to be shortest path or anything AI-like, just a way to get from A to B) I have no idea where to start at all, unfortunately
