Today I gave three talks at my local LUG. The first was my latest SE Linux talk (I’ll put the notes online soon). The second was a talk about voting. I asked for a show of hands, who has already decided which party they will vote for at the next federal election (about 12 people […] I have seen buses used for tours that contain bunk beds. If one or more such buses were hired then a group of Linux people could go on a moving Linux conference. This would have to take place in an area with many reasonable size cities in a close area and where there is a […] This weekend I went to the Ballarat install-fest, mini-conf, and inaugural meeting of the Ballarat Linux Users’ Group (BLUG). This was the second install-fest, the first one was quite successful so it was decided that there was demand for a second. I suggested that what we should do is get some of the more experience […] One thing that has always surprised me is how few people talk to speakers after they have finished their lecture. A lecture might have many questions and the questions may be cut off, but when the speaker leaves the room they will usually do so alone. When I give lectures at conferences I’m always happy […] echo 1 > /proc/sys/vm/block_dump The above command sets a sysctl to cause the kernel to log all disk writes. Below is a sample of the output from it. Beware that there is a lot of data.

I advocate it to appropriate people, which is mostly non-programmers – but as I mentioned that means a larger proportion of the population than to whom I can advocate Debian. It’s […] Today I discovered a bug in one of my programs, it called system() and didn’t correctly escape shell eta-characters. Fortunately I had written custom SE Linux policy for it which did domain_auto_trans(foo_t, shell_exec_t, very_restricted_t) so there was no possibility of damage. The log files (which were not writable by the daemon by both SE Linux […] The dunc-tank project was established to raise money to compensate some Debian developers who are essential to producing a timely release of Debian. There has been a lot of acrimoneous debate about whether this is a good or bad thing. The positive side of it is that the release managers will get to spend more […] This weekend I was in Sydney for Ruxcon. Ruxcon is a computer security conference with a focus on penetration testing and related skills. The presentation on Unusual Bugs by Ilya van Sprudel was particularly interesting. He spoke about a number of issues that could do with some improvement in Linux, I will file some bug […] A common problem with Linux systems is when Windows users press CTRL-ALT-DEL at the login prompt and reboot the machine. To fix this some people change the ^ca line in /etc/inittab to just disable the reboot function. However this is not desirable because sometimes you want to reboot a machine with a simple keypress.
