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.

I'm a retired, General Officer level U.S. Army Intelligence leader who's been in INFOSEC since the 1980s, when it was mostly mainframes & Novell. Certifications came after, when I was off leading in the PSYOP / counternarrative side of IO, so I don't have any & cannot claim to be any sort of technical expert--but I can still (in sha' Allah) talk intelligently with folks who ARE technical experts & help connect such discourse to strategic outcomes.

I'm also coming onboard as Associate Director of an academic Global & National Security Policy Institute, a Twitter refugee sold on the fediverse as the most resilient architecture to avoid getting co-opted by billionaires or governments, an observant Muslim & aspiring alim, and a senior EDUCATIONAL Technology scholar.

As I said in my old Twitter bio, "Yep--weird." :-D
