Regex lexer for pygments

photo_small I am currently writing on my thesis about malicous detection systems and started using indirectly pygments with latex. I am pretty happy with it since it supports all kind of text/code highlighting. That was why I was a bit surprised when I saw that there was nothing for plain old regular expressions. Normally I would create a pull request for such things but I am currently a bit short of time and this is far from being perfect. Still I want to s []

Rancher v2 and a story about re-deploying nodes

ODB2, DealerTool and Linux

photo_small Sometimes I am wondering myself why people pay a lot of money for closed-source software when they can use open-source for free. This time I simply wanted to read my ECU for errors and some sensor information. If you quickly search for "Triumph" and "ECU" you will end up with expensive Window Programms.
