Hi everyone, yesterday I had to debug a failing join on a large domain for a group of primary schools with 1000+ desktop and 10k accounts.

After some investigation into dbcheck (4.1.17) and some "human powered" valgrind like evalution using pudb, I came to the

Hi, I'm successfully using winbind to authenticate a debian sarge workstation against an nt4 server. Works a treat. However, I have an odd situation where a user logs in for the first time as "John Smith" and gets created a "John Smith" directory in /home. *Then*, if they log in as "john smith", they get a second directory created as "john smith" in

Hi, I have the following conceptual / interpretative question regarding random effects: A mixed effects model was fit on biological data, with observations coming from different species.

Hi folks, I have a dataset from a trial measuring the subjects' pupils. There are many measurements, all of which must be analysed in a similar fashion; so if I get the analysis right for one of them, I've got them all.
