    Howto: Live migrate to software RAID 1

    Feel insecure about your data? Don’t trust your harddrive anymore? Use this howto to migrate your running Ubuntu Linux system to software RAID 1. Before starting off, I assume you have your running system on /dev/sda and your new harddrive is called /dev/sdb. Boot up your system and install the mdadm package. We now have to create partitions [...]

  • Pinnacle DVB-T stick remote

    Pinnacle DVB-T stick remote

    Another post about that Pinnacle DVB-T stick? No, this one is about the remote! I wrote that the remote wasn’t completely working yet. Apparently, there is a driver for this remote or the stick that converts the buttons from the remote to “keyboard events”. Meaning I can type the number 0-9 with my remote for [...]

  • Pinnacle DVB-T stick on Ubuntu Jaunty

    Pinnacle DVB-T stick on Ubuntu Jaunty

    Yesterday I decided to buy the Pinnacle DVB-T Stick (also known as Pinnacle TV Stick 72e) to watch some free-to-air channels. In the shop I searched on Google for Linux support, to make sure I didn’t have to return the product. The first few hits seemed positive (2 years ago), so I decided to take [...]

  • Fixing FreeNX on Fedora 11

    Fixing FreeNX on Fedora 11

    Today I had some problems getting FreeNX to work on Fedora 11. FreeNX is a VNC-like system that has much better performance than VNC itself. It is therefore very usefull if you would like to access your computer via your Cable or ADSL connection. After installing FreeNX in Fedora, whenever I connected, I got some strange [...]

  • Using GNU screen as virtmanager for KVM

    Using GNU screen as virtmanager for KVM

    After my last post about KVM, somebody emailed me, asking how I use KVM’s serial console in combination with screen. It’s a rather simple, but really usefull solution if you think tools like virtmanager are too much for you and you don’t like to use VNC. So this post will try to explain it to [...]

  • Boot Ubuntu livecds in KVM without VNC

    Boot Ubuntu livecds in KVM without VNC

    This post is just for the sake of documenting this. A while ago I came across a blog post written by an Ubuntu developer (I believe) which gave a nice tip on how to boot a livecd in KVM without VNC. Yesterday I needed this feature again, but was unable to find it. I needed to boot [...]

  • My first Cherokee patch

    My first Cherokee patch

    I’ve been playing with Cherokee (the light-weight web server) for a while now. I really like the way their configuration file can be managed with cherokee-admin. This is basically a secured web page that provides a convenient interface to all of Cherokees settings. Although Cherokee is looks so great, I can’t switch the Ivaldi web server [...]

  • Monitor Postfix with Cacti and SNMP

    Monitor Postfix with Cacti and SNMP

    Today I configured Cacti and SNMP after I saw the graphs of a friend. He had graphs for Postfix, which showed statics like sent/received/rejected. After a little search on the internet, I found a post on the Cacti forum. At first I couldn’t get it to work, but after running the script manually (instead of via [...]

  • Testing Ubuntu Jaunty with UXA

    Testing Ubuntu Jaunty with UXA

    I’ve been testing Ubuntu Jaunty for a few weeks now and after using it for a day or two, my memory filled up. Recently I found out that this was caused by Compiz. Apparently if you use UXA with the new Intel drivers, Compiz will start to leak memory. After only 8 hours of usage, [...]

  • Using imapproxy to speedup webmail

    Using imapproxy to speedup webmail

    Yesterday, I discovered a great way to improve the speed of your webmail client. Two friends of mine were talking about something called imapproxy. Apparently this is a simply brilliant tool. It was invented because the web is stateless, but imap is not. Your webmail client (for example Roundcube) will reconnect to the imap server everytime [...]
