This article is part of the LWN Grumpy Editor series. LWN readers need not be told that this publication is strongly biased in favor of free software. So it should come as no surprise that we follow the path we preach for others. The entire LWN operation is based on free software, from our desktops to the web servers. We are a free software success story, just like all those other companies using free software.
