David Chisnall (*Now with 50% more sarcasm!*)
@[email protected]

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.

Header image is a novelty desk sign that, instead of a name or title, reads "Welcome to the shitshow," nicked from someone here. Avatar is a selfie of me standing up, outside, with a neighborhood of palm trees and stucco houses behind me. I'm wearing light sunglasses, red lipstick, and a sleeveless shirt with a balloon animal print. Not shown: my walker.

Most posts auto-delete after 3 months, so grab that meme when you see it! :)
