He/him, I share cyber wisdom, humor, and other info. If I’m upsetting Democracy’s adversaries. I’m on the right track.
As a cyber pro and concert-level pianist, founder of PianoBarCon, and occasional melodica carrier at events. 
My opinions don’t necessarily match my past, present, or future employers, but not for lack of effort on my part.

If you really want to get under the hood, enjoy this autobiographical song i wrote called “Without You I’d Not Be Me”.

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.
