I am Director of System Architecture at SCI Semiconductor and a Visiting Researcher at the University of Cambridge Computer Laboratory. I remain actively involved in the project, where I led the early language / compiler strand of the research, and am the maintainer of the Platform.

I was on the FreeBSD Core Team for two terms, have been an LLVM developer since 2008, am the author of the GNUstep Objective-C runtime (libobjc2 and associated clang support), and am responsible for libcxxrt and the BSD-licensed device tree compiler.

Opinions expressed by me are not necessarily opinions. In all probability they are random ramblings and should be ignored. Failure to ignore may result in severe boredom and / or confusion. Shake well before opening. Keep refrigerated.

Warning: May contain greater than the recommended daily allowance of sarcasm.

Working at front lines of the IT and having fun there. Been around the Internet since 1992 and still in awe what has become of that little baby. Currently wanted for repeated "Nerd Sniping" on all continents.

Personal interests:

- IT Security
- Computer Games & TTRPGs
- Cycling
- Cooking & Baking
- Books, Movies, TV-Series (mostly F&SF)
- Everything that blinks, has buttons to press and looks remotely gadgetoid

Everything i write, post, tweet, blog or blurp is just my personal opinion and is not the opinion or policy of my employer, my cat or my goldfish.

I post in English and German. Will try to mark each post correctly, but errors happen. Sorry for that.

I appologize if I am not following you back. This happens as my stream is already getting more posts than I can read.
