Interesting links
The following links I have collected over the past decade or so and found useful or interesting. I don't check for dead links though, so some of them might not work or point to other sites now. Responsibility for the content of the sites to which the links point lies entirely with the owners of the respective sites, and that content does not necessarily reflect my opinions or those of my employer.

Q: "If you were young again, would you start writing TeX again or would you use Microsoft Word, or another word processor?"
A: "I hope to die before I have to use Microsoft Word."

open Windows.
- The day Microsoft makes something that doesn't suck is probably the day they start making vacuum cleaners.
