  • Linuxdistribution för äldre?

    Som en del i projektet att fÃ¥ mina farföräldrar att använda en dator och (helst) Internet försöker jag hitta en linuxdistribution som är enkel att lära sig använda*. Alternativen jag tittar pÃ¥ just nu är EasyPeasy, som är en Ubuntuklon med ett GUI anspassat för netbooks, Linux Mint, även det en Ubuntuklon och här med…

  • Dennis Ritchie, tack för allt!

    Den 12:e oktober gick Dennis Ritchie bort efter en längre tids sjukdom. Han lever dock vidare genom C och UNIX på samma sätt som han gjort dom senaste 40 åren. Tack för allt! Se även mitt inlägg på .SE-bloggen

  • 6 Ways To Kill Your Servers – Learning How To Scale The Hard Way

    Good article over at HighScalability.com about what happens when a coder, even an experienced one, has to scale out a web site under time pressure. The most important lessons in my opinion are caching, tweaking configuration and stress testing.

  • How to be a better sysadmin

    Matt Simmons over at Standalone Sysadmin wrote about xenophobia and elitism among sysadmins and I couldn’t have written it better myself: The way that I’ve found that seems to work best for me in understanding other people, and having them understand me, is to put myself in their place, and consider the situation from their…

  • Man trodde ju dom skulle lära sig av varandra…

    Nu har D-Link ocksÃ¥ gjort det… Vad kan man säga mer än att historien upprepar sig. För nästan precis fem Ã¥r sen sÃ¥lde Belkin en router som gjorde om slumpmässiga dns-uppslag (eller om den “bara” kapade vissa HTTP-sessioner) för att göra reklam för en ny funktion i deras router. Nu har tydligen D-Link fÃ¥tt för…

  • daemontools and ucspi-tcp on Hardy Heron

    I was about to install daemontools and ucspi-tcp on Hardy Heron (Ubuntu 8.04) when I found that the packages build-daemontools et al was not in the archive anymore! Instead of digging about what happened I found out that Intrepid Ibex[1] has some packages. So what I did was download the packages daemontools, daemontools-run and ucspi-tcp,…

  • Private methods in PHP programming – response

    Felix over at Debuggable wrote an interesting article about private methods. He thinks it’s not a very good thing to use, but, kudos to him, doesn’t rule out the possibility. He argues that he doesn’t have any formal education in programming and development, but I don’t think that matters much at all since he seems…

  • Power consumption on office switches

    Russel Coker wrote about switches and cables, and thinks putting a “dumb switch” on every desk is a good solution for office networking. He’s got a couple of valid points, for example that it’s possible to use less cables from the patch room, no (or less) dependency on network gurus and so on. What he…

  • No 404 page when using a static front page

    in

    I was setting up a wordpress blog (latest version, 2.5) a couple of days ago, and added the great plugin Google XML Sitemaps. I wanted a static frontpage with a couple of blog posts below it, so I modified the Kubrick theme a bit (added another template to use for that page, no biggie). When…
