Jag och mitt skal – Verktygslådan, introduktion och filosofi
Filosofin bakom verktygslådan var ett mycket viktigt koncept när Unix (av vilket GNU/Linux i stort sett är en klon) först designades och utvecklades. Olyckligtvis, i dagens värld av “webben” grafiska gränssnitt, “moln” och andra buzz-fjanterier, verkar denna filosofi till viss del glömts bort. Det är synd, eftersom denna filosofi ger oss den kraftfulla mentala modell,…
Jag och mitt skal – Introduktion till terminaler och shells
Denna video är ju rolig på sitt vis, många tar den säkert dock på allvar, och tror verkligen att terminaler och skal i *nix (Unix, GNU/Linux, BSD, jag kommer i fortsättningen skriva *nix) är något svårt och komplicerat att använda sig utav. Men så är det inte, terminalen, och skalet, är det Sanna sättet att…
How to set up a SIP trunk in the Asterisk PBX
In my previous article we configured Asterisk with some SIP-devices, and created a basic dialplan so that they could dial eachother. We also created two additional extensions for test purposes. This time I will show you how to configure a SIP trunk, and add extensions in the dialplan so that the telephones can dial out through…
Djupare in i bloggandets värld, motstretandes, men hyfsat fascinerad
Sådär.. första steget i ett litet optimeringsexperiment, då får vi se om det ger något resultat i form av någon mer besökare kanske. Prövar bland annat att pinga (denna gång menas blog-ping, inte ICMP) http://www.frisim.com/ automatiskt från WordPress vid postande. Detta är väl mest ett test, alternativt en liten rant. Bland all skit som skrivs…
Four years after The Pirate Bay raid
Apparently, yesterday it was exactly four years since (the) The Pirate Bay raid. Time really flies.. I remember it well. I think I probably still have the police lists of the confiscated computers in some dusty directory, they leaked, or was made available some time after, if I recall correctly that is.. (A few minutes…

Pac-Man’s 30th Anniversary
Today is Pac-Man‘s 30th birthday. Happy Birthday Pac-Man. Google has a nice javascript logo in the form of a Pac-Man game today, with a level including the letters “G o o g l e”, nicest one so far I think, such things we like.
Installing Debian Lenny on an Asus EeePC 900, part two
I have had my EeePC for a while now, and I have set it up how I want it, for the most part. When I wrote the first part, about installing Debian on an Asus EeePC 900, I wasn’t very detailed about what I had, or were going to do, to make it run as…
Exercising civil rights and duties
Today is the EU parliament election in Sweden. I have been exercising my civil right and duty, and voted. I think it’s important to do so, even if one isn’t very politically active otherwise, the least one can do is make an opinion and vote when there is an election. I can report that things…
Getting indexed by Google, don’t repeat this mistake
A few days ago I was going to “deploy” a site I had been working on. It is using WordPress. When I set things up and wrote pages and made it do a bit of what I wanted, I had set it to be private, in the WordPress Settings->Privacy->I would like to block search engines,…
