I've used the document revision management system Subversion for a few years now and find it to be an excellent tool that has never given me any problems. Until this week, that is. I was helping to set it up on a web server that has Fedora Core 4 as its OS - we wanted to have a central code repository for the various projects we worked on and it was a logical step to place it there.

Here's a wonderful explanation of why Microsoft's "open" OpenXML "standard" is a wolf in sheep's clothing: http://www.robweir.com/blog/2006/01/how-to-hire-guillaume-portes.html In short, the specification is littered with little tidbits which say that to properly display a file you must understand details of how 12 year old software (Word 95) worked, or reverse engineer it.... And that, folks, is why I don't use Microsoft software and stopped buying their junk several years ago. Update: Just to better explain why this is a problem, there is no guarantee that Microsoft is using its own specifications in its own software, namely Office 2007.
