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. The talk didn’t go quite as well as I had desired, I ended up covering most of the material in about half the allotted time and I could tell that […] Strange dbus error from the KDE power monitoring tool No related posts. 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.

The first and easiest method I discovered is to keep a 2L bottle of water in my car. After it’s been parked in the sun on a hot day I pour the water over the windows. […] As part of my work on Xen I’ve been playing with Xephyr (a replacement for Xnest). My plan is to use Xen instances for running different versions of desktop environments. You can’t just ssh -X to a Xen image and run things. One problem is that some programs such as Firefox do strange things to […] I have been asked for advice about long-term storage of documents. I decided to blog about it because my thoughts may be useful to others, and because if I get something wrong then surely people will correct me. ;) Many organizations are looking at using computers for storing all documents. This gives savings on the […] |
