I won’t be visiting the US in the forseeable future. For some time I have been concerned about the malfunctioning legal process and other related issues that arose from the so-called “War On Terror“. But the most recent news is that the TSA may just copy all the contents of your laptop or even steal […] Someone asked on a mailing list how to redirect output from a running process. They had a program which had been running for a long period of time without having stdout redirected to a file. They wanted to logout (to move the laptop that was used for the ssh session) but not kill the process […] February 27th, 2008 | Tags: Best Posts, Most Popular | Category: unix-tips | 10 comments - (Comments are closed) Finally I found the URL of a device I’ve been hearing rumours about. The HotPlug is a device to allow you to move a computer without turning it off [1]. It is described as being created for “Government/Forensic customers” but is also being advertised for moving servers without powering them down. The primary way that […] For a while I’ve been reading the Lenovo blog Inside The Box [1], even though I plan to keep my current laptop for a while [2] (and therefore not buy another Thinkpad for a few years) I am interested in the technology for it’s own sake and read the blog. A recent post concerns a […] January 2nd, 2008 | Tags: Best Posts, Environment, Most Popular | Category: Review | 6 comments - (Comments are closed) Glen Turner writes about silly people who think that fluorescent lights don’t save energy over their lifetime [1]. A compact fluorescent light (one that is designed for the same socket as an incandescent globe) is not the most efficient light source, the Luminous Efficiency page on Wikipedia [2] lists a CFL as having an efficiency […] January 1st, 2008 | Tags: Best Posts, Environment, Most Popular | Category: Politics | 23 comments - (Comments are closed) Today I released new versions of my Bonnie++ [1] benchmark. The main new feature (in both the stable 1.03b version and the experimental 1.93d version) is the ability of zcav to write to devices. The feature in question was originally written at the request of some people who had strange performance results when testing SATA […] I recently was giving away some old P3 and P4 machines and was surprised by the level of interest in P4 machines. As you can see from my page on computer power use [1] the power use from a P4 system is significantly greater than that of a P3. The conventional wisdom is that the […] November 26th, 2007 | Tags: Most Popular | Category: Uncategorized | 8 comments - (Comments are closed) Update: Due to the popularity of this post I have created a T-Shirt and put it on sale at http://www.cafepress.com/email_eula . Update: Unlike most of my blog content I permit anyone to copy most or all of this post for commercial use (this includes blogs with google advertising) as long as they correctly identify me […] November 20th, 2007 | Tags: Best Posts, Most Popular | Category: Mta | 20 comments - (Comments are closed) When advogato.org was still cool I signed up to it. It was an interesting research project in skill metrics (determining the rating of people’s coding skills by the votes of others and weighting the votes by the rating of each person), and it was nice to be rated Master soon after I joined. I still […] November 18th, 2007 | Tags: Best Posts, Most Popular | Category: Blogging | 11 comments - (Comments are closed) Should you use software or hardware RAID? Many people claim that Hardware RAID is needed for performance (which can be true) but then claim that it’s because of the CPU use of the RAID calculations. Here is the data logged by the Linux kernel then the RAID-5 and RAID-6 drivers are loaded on a 1GHz […] November 16th, 2007 | Tags: Best Posts, Most Popular | Category: Linux | 17 comments - (Comments are closed) |
