Running a server means keeping ownership of your data and choosing your own services such as blogs, todo lists, project management or source code repositories. These are recipes for installing and managing them.
Being able to rely on your memory is one of the most important aspects of having a stable PC. Thus, paying extra for premium memory seemed like a wise choice to me.
Yet I have been surprisingly unlucky with my memory.
In this post I’ll show how to identify broken memory cells and how to prevent Windows and Linux from accessing them, resulting in a stable system while discarding only a few Kilobytes of memory.

After running Drupal for 3 years, then Joomla for another 3 years, I have now moved my website to WordPress — after almost picking Drupal again. So here’s the obligatory write-up of my experiences, why I switched and where I think the problems lie in those three CMSs.
In August 2006, after trying about a dozen CMSs, I went live with my website built on Drupal. It promised the greatest flexibility and had a very active community with countless free plugins.
I was happy with that, for a time. Drupal enabled me to define my own category trees, article types and mix WYSIWYG editors with filters for highlighting code, disarming HTML code in posts and letting users write comments.
Read MoreI’m pretty sure that by now, everyone reading this blog has heard of or probably even played Minecraft himself. It’s a sweet little game that tosses you into a simplified world that you can freely (and easily!) shape in any way you want. Your tasks: feed yourself, keep monsters out of your buildings and build something remarkable.
Minecraft can, of course, be played with any number of players online. All you need is a server with shell access and Java on it. If you also have Mono on your server, you can use McMyAdmin, a very convenient web frontend for the Minecraft server to manage users and perform automated backups.
Read MoreBeing an adherent of Continuous Integration, I need a build machine that runs round the clock even when my workstation is turned off. As I’m running a small home server, this wouldn’t be an issue — if it weren’t for the fact that my home server runs Linux and 99% of my development happens in Windows. So I use virtualization to run a small Windows system on top of my home server.
In the past I used VMware for this job. VMware worked well for me and performance was quite good, but now that I’ve switched to a fully headless system, I noticed that the vmware-server package pulls in most of the X11 libraries – which I’m not particularly keen on having on my system due to their compile times.
So I went shopping for some alternatives. KVM sounded interesting (and was the leanest virtualization solution I could find), but the Gentoo Wiki stated that Windows didn’t work in qemu with recent kernels, so I went looking on – and found VirtualBox. This article explains how to set up VirtualBox on a headless Gentoo system.
Read MoreIf you haven’t heard of Continuous Integration yet, it’s the practice of setting up an automated system that rebuilds projects automatically whenever someone commits a new change to your source code repository. It ensures that whatever is in your repository builds and runs: automated builds usually involve compiling, running unit tests and packaging the installer.
To do continuous integration, you need a tool that monitors your source code repository and starts the builds – a continuous integration server. My weapon of choice is TeamCity, a free CI server written in Java with first-class support for .NET and its toolchain (like NAnt, NUnit, NCover or PartCover).
TeamCity is pretty easy to deploy – the Windows package has an installer which leaves you with a fully working server after just a few clicks and even the Linux package is pretty simple to deploy: Download, unzip, run runAll.sh and you’re done. To properly integrate it into a Linux server (so it will come back up after rebooting and can be reached via HTTP without having to run either Apache or TeamCity on a non-standard port), you’ll need to run your own Tomcat server.
This guide will tell you how to do it!
Read MoreCourier not only is an excellent mail server, it also ships with a mailing list manager that can be used to build mailing lists without relying on a third party provider (which usually has the bad habit of adding advertising text to the emails being forwarded).
Here’s a small tutorial that explains how to set up a new mailing list using couriermlm.
Read MorePlease excuse the current flurry of Linux articles. I’m moving servers and this is my way of writing notes to myself and possibly helping out others. Normal service will resume shortly ;-)
This article is a follow-up to my guide on Installing Courier on Gentoo. As long as you have a working Courier installation on your system, there should be no issues following this guide.
Running a mail server without some kind of spam filtering is just insane these days. SpamAssassin is a nice solution, especially if you run SpamAssassin during the SMTP transaction to reject spam while it is being uploaded to your server.
Read MoreOn my previous system, I had used qmail (netqmail actually, which is qmail with some patches). Qmail is moderately difficult to set up and in its 3 years lifespan on my system, it has broken down on several occasions. That’s why I decided to use another mail server when I moved my domains to a different system.
Because the Courier IMAP server has never let me down before, I decided to give the Courier Mail Server a chance. Lots of people are using Courier IMAP to access their mail but Exim, Postfix or Qmail to accept incoming emails. Even the Gentoo Wiki contains various HowTos for these combinations, but not a single one for a homogenous Courier setup. After trying out Courier, I don’t see why, so this is my attempt to rectify the situation (and to remember what needs to be done for the next time I’m moving my domains to another system!)
Read MoreIf you want to download torrents on your Linux system, there are several clients to choose from. One of the nicest and fastest clients is rTorrent. It is full-featured, supports encryption, dynamic host table exchange and achieves fantastic download speeds.
But its best feature probably is that it isn’t bound to any windowing toolkit. You can install one of its GUI frontends to manage it on your fancy KDE 4 desktop machine, but you can also run it on a headless system and manage torrent from a text-only console. And if you happen to run it on a home server like me, there’s wTorrent, a beaufitful AJAX-driven web frontend that allows you to manage your torrents in your browser.
Installing wTorrent isn’t the easiest thing to do, so, as when I tried to get the best out of my SSD, I decided to write this small article explaining how to do it. I’m using Gentoo Linux, but it shouldn’t be too hard to apply this article to another Linux distribution.
