Okay, so I can’t really go into too much of the big picture since this is from the day job, but I can certainly tear into gethostbyname_r() a bit.

For part of what we’re doing, we’re sending a RADIUS message using the freeradius project’s radius client library. So, nice and simple (after you’ve done some setup):
[cc escaped=”true” lang=”c”]result = rc_acct(rh, 0, send);[/cc]
Easy enough, right?… Read the rest

Back when I was finishing my undergrad degree, my final year project (which is a big part of the final degree exams in Trinity) was in Java on a Sun SPARCstation 4 (at the time, one of the more powerful boxen you could get access to as an undergrad). The project was a fair bit of fun, writing a robot controller in Java just as 1.2 was coming out of beta. Lots of long hours were spent in that lab with three or four others working on their projects, and quite a few all-nighters interspersed with the odd game of networked bomberman ūüėÄ I even managed to get a published paper out of it.… Read the rest

Ray asked to see what the output of the kada2 script I’ve been working on looks like – only problem is that I’ve been using a real datafile for development, so it has people’s names in it. To avoid any shoutyness, one quick python script to read in the members.kda file and write it back out to test.kda with all the names changed to John Smith; then a quick run with this file as the members.kda file and some imagemagick conversions and viola, the current kada.py output.… Read the rest

As I mentioned before, after writing a python script to read in Kada’s data files on the rifle club shooters’ scores and calculate new ladders, the next step is output that’s a bit fancier than the straight ASCII text dump:

This does the basic job that the original system did (actually, it does a bit more – the asterisks mark out those shooters who haven’t yet shot enough cards to get on the ladder, but they’re still listed as an incentive for them to shoot more cards – the current system doesn’t do this).… Read the rest
