I can neither confirm nor deny that I've done something similar to this before.
Edit: Went to buy one.... sorry guys I can't justify 9 dollars for shipping for one shirt. I'll have to do like I did last time and buy a couple at once.
If we ever get BSD going on here, and get a shirt going we should modify the phrase that's used on Allan Jude's show. The Place to B...SD sounds low quality. It needs to be The place to B. And then have the BSD logo underneath.
I know that Haiku is not Linux. But when I read the title, I thought we were being given news on the Haiku OS.
I don't want my Linux merch sad. I want it either happy or snarky. After a day spent learning the syntax of Apache's mod_rewrite - well, making mistakes stemming from my lack of knowledge of it, then learning it- I had the idea of making a local shop print me a t-shirt with the definition of an Apache virtual host configured as a reverse proxy for Google as commentary about what my work's like. If you offered those, I'd buy one. I was thinking of making ServerName my name, but I guess it could be 'IT' or something similarly generic.
