While attending LCA it occurred to me that the lecture notes from all the talks that I have given lack a copyright notice. So I now retrospectively license my lecture notes in the manner that probably matches what everyone was already doing. The Creative Commons web site has a form to allow you to easily […]

Today I have released a significant new version of my mail server benchmark Postal! The list of changes is below: Added new program bhm to listen on port 25 and send mail to /dev/null. This allows testing mail relay systems. Fixed a minor bug in reporting when compiled without SSL. Made postal write the date […] It appears that some people don’t understand what right-wing means in terms of politics, apart from using it as a general term of abuse. I recommend visiting the site http://www.politicalcompass.org/ to see your own political beliefs (as determined by a short questionnaire) graphed against some famous people. The unique aspect of the Political Compass is […] This morning at LCA Andrew Tanenbaum gave a talk about Minix 3 and his work on creating reliable software. He cited examples of consumer electronics devices such as TVs that supposedly don’t crash. However in the past I have power-cycled TVs after they didn’t behave as desired (not sure if it was a software crash […] Firstly for smooth running of the presentations it would be ideal if laptops were provided for displaying all presentations (obviously this wouldn’t work for live software demos but it would work well for the slide-show presentations). Such laptops need to be tested with the presentation files that will be used for the talks (or pre-release […] This afternoon I gave a talk at the Debian mini-conf of LCA on security improvements that are needed in Debian, the notes are online here.

We have a list of 10 (famous) girl geeks from CNET and one from someone else. The CNET list has Ada Byron, Grace Hopper, Mary Shelly, and Marie Curie. Mary Shelly isn’t someone who I’d have listed, but it does seem appropriate now I think about it. Marie Curie is one of the top geeks […] A post by Scott James Remnant describes how to hide command-line options from PS output. It’s handy to know that but that post made one significant implication that I strongly disagree with. It said about command-line parameters “perhaps they contain sensitive information“. If the parameters contain sensitive information then merely hiding them after the fact […] 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.
