I have just given my parents a new computer, and part of the upgrade process lost their email passwords (which were stored in KDE preferences – this seems to happen every time KDE is upgraded). The only password that is not under my control is the password for their Optus account. So I had to […]

I’ve been having problems with one of my Xen virtual servers crashing with kernel error messages regarding OOM conditions. One thing I had been meaning to do is to determine how to make a core dump of a Xen domain and then get data such as the process list from it. But tonight I ended […] One item on my todo list is to set up a bunch of email addresses on sub-domains of domains that I am responsible for (with the consent of all people involved of course) and perform various actions to get the addresses noticed by spammers and measure how effective the various anti-spam measures are. As part […] I recently had to decommission an old Linux server and replace it with a new machine. When I was about to turn it off I noticed a power cable of the type used for IDE hard drives leaving the Linux server and entering an NT server that was in the same rack! It turned out […] My post about Why Hydrogen Powered Cars Will Never Work has received a record number of comments. Some of them suggested that carbon geo-sequestration (storing carbon-dioxide at high pressure under-ground) is the solution to the climate change problem. The idea is that you can mix natural gas or coal gas with steam at high temperature […] Here is a transcript of a lecture by George Monbiot about climate change and what we need to do. The latest scientific evidence suggests that we need to cut emissions to zero by 2030 to avoid significant increases in the sea level over the next century, George describes some options that will form part of […] I just needed to test something so I mounted the filesystem of one of my Xen domains in the Dom0 and chroot’d into it (I didn’t need the overhead of running a DomU for a quick test). Then strangely I found that my chroot environment had no apt-get and no dpkg installed. After a small […] BMW has released a new prototype hydrogen powered car. The bmwworld.com web page about it claims the cruising range is 190 miles. Added to the 400-mile range of the normal fuel tank, the 745h can go 600 miles between fill-ups. The first issue is that 10 miles are not accounted for (maybe it finishes the […] I just noticed that my post about LED Headlights in an Audi Sports Car was linked from audi.host4blogs.com. Strangely they took some of the words from my post, added some other apparently random words to make it look like a response, and then linked to my post. Having summaries of my blog posts appear on […] |
