  • Cron, crontab example reference and how to run things periodically in GNU/Linux and Unix

    Cron is a job scheduler found in most Unix-like operating systems. “Chronos”, which is the Greek word for “time”, is where the name cron comes from. Cron makes it possible to schedule jobs, which can be commands, a series of commands, or scripts, that you want to run periodically. Common uses are backups, notifications, periodic…

  • Fixing missing menu entries of Opera and Skype in Debian GNU/Linux

    Unfortunately the third-party packages of Opera and Skype do not contain menu entries for the Debian menu system. Not very surprisingly one might think, but I just think it’s sloppy. If you, like me, like the Debian menu system and want Opera and Skype available in it, do the following to solve that, until the…

  • Modems & Bulletin Boards, The Computer Chronicles

    This Sunday’s video (I will from now on try to post atleast one video from this series, or another, each Sunday (even though it technically is Monday in this part of the world)) is about modems and bulletin boards (BBS:es). I also have to recommend the movie/series “BBS: The Documentary” which is very interesting and well made.…

  • 3 WordPress plugins

    Yesterday I decided to change the permalinks structure of this site. I wondered if WordPress had redirection built into to the core, but it seems it does not yet. But there are many plugins, like always, providing the needed functionlity. At first I looked at one called Redirection, but it was not really what I was…

  • Restaurang Emanuel lägger ner verksamheten

    Eftersom de själva, på sin egen webplats, http://restaurangemanuel.com/ endast har lagt ut ett Microsoft Word-dokument, tänkte jag att någon bör ge det hela lite mer uppmärksamhet. Restaurang Emanuel ligger (eller väldigt snart låg) i huset där jag bor. Jag har ätit där några gånger såklart, maten är bra. Fastigheten har haft ett antal olika ägare…

  • A revised opinion on apache2-mpm-prefork and apache2-mpm-worker, and php5 and php5-cgi on Debian, regarding performance

    It’s now over a year since I wrote about “Exchanging apache2-mpm-prefork for apache2-mpm-worker, and using php5-cgi on Debian to improve performance“. Since then I have re-evaluated my opinion about running apache2-mpm-worker and php5-cgi on a low memory machine, specifically a virtual machine running under Xen, running Debian.

  • UNIX, The Computer Chronicles

    This is a very interesting episode, if you watch it, you can often draw paralells to todays reality, and can think back on what actually happened, and how long it has taken for some things. The interesting thing with many, and in particular this episode of Computer Chronicles, is that it could have been recorded…

  • Fri mjukvara i svensk skola, tyvärr en nyhet

    Det är ganska bedrövligt att detta är en nyhet, att det inte är normen nuförtiden. IDG har skrivit en artikel om en skola som kör Ubuntu, på begagnad hårdvara. Om man tål att läsa IDG (klicka inte på kommentarerna, som alltid fulla av idioter) och bortser från den usla korrekturläsningen, skolan har nämligen enligt IDG…
