The Age has published a remarkably stupid article about terrorism titled “It’s hard to prevent the hard to imagine” which contains some amusing statements such as “a plan to use liquid explosives hidden in soft-drink bottles and destroy commercial jets crossing the Atlantic. The scale of this plot, combined with the innovative bomb design, threatened […]

The reason I watched it was not to learn about how to correctly write such programs, but so that I could recommend it to other people. Recently I have had problems […] July 2nd, 2007 | Tags: Best Posts, Most Popular | Category: Linux | 10 comments - (Comments are closed) Xen (a system for running multiple virtual Linux machines) and has some obvious benefits for testing Heartbeat (the clustering system) – the cheapest new machine that is on sale in Australia can be used to simulate a four node cluster. I’m not sure whether there is any production use for a cluster running under Xen […] June 24th, 2007 | Tags: Best Posts, Most Popular | Category: Ha, Virtualisation | 2 comments - (Comments are closed) A question that people often ask about wind power (and was asked in the comments section of my previous post) is what can be done when the wind speed decreases in an area. There are several methods that can be used to address this problem. The easiest option is to simply have wind farms spread […] June 18th, 2007 | Tags: Environment, Most Popular | Category: Politics | 3 comments - (Comments are closed) In response to my comment and post about the cost of driving to work there was a comment on the blog post I responded to suggesting that a small car is better value for money than a hybrid car. The claim was made regarding a Nissan Pulsar, but to investigate this I decided to compare […] June 11th, 2007 | Tags: Environment, Most Popular | Category: Cars | 39 comments - (Comments are closed) In a Heartbeat cluster installation it may not be possible to have one STONITH device be used to reboot all nodes. To support this it is possible to have multiple STONITH devices configured that will each be used to reboot different nodes in the cluster. In the following code section there is an example of […] May 30th, 2007 | Tags: Best Posts, Most Popular | Category: Ha | One comment - (Comments are closed) I have now got a Debian Xen domU running the strict SE Linux policy that can boot in enforcing mode. I expect that tomorrow I will have it working with full functionality and that I will be able to run another SE Linux Play Machine in the near future. After getting the strict policy working […] May 18th, 2007 | Tags: Best Posts, Debian, Most Popular, Selinux | Category: Security | 8 comments - (Comments are closed) When I first put my new blog online I didn’t think to set the custom permalinks option to avoid having /index.php in all URLs (which wastes a few bytes and looks nasty). So I decided to change to better URLs but unfortunately many people have already bookmarked the bad URLs. I wanted to give a […] May 6th, 2007 | Tags: Best Posts, Most Popular | Category: Blogging | 3 comments - (Comments are closed) The web site http://au.ratemyteachers.com/ allows Australian students to rate their teachers. Ratings are anonymous and give teachers a score out of 5 as well as allowing students to comment on teachers.

I’ll blog about installing dom0 later when I have a test system that I can re-install on (my production Xen machines have the dom0 set up already). The following documents a basic Xen domU (virtual machine) installation that has an IP address in the […] January 1st, 2007 | Tags: Best Posts, Debian, Most Popular | Category: Virtualisation | 2 comments - (Comments are closed) |
