I am eminently qualified to speak from experience about a variety of dumpster fires.

ICS cybersecurity person, @pancakescon organizer, martial artist, marksman, humanist, level 14 Neutral Good rogue, USAF retired. Speaker available for gigs.

Gin connoisseur. Rodent parent. Some dipshit from Chicago. Now an immigrant in Melbourne.

I post *very serious* things about infosec. Thoughts are entirely my own.

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.
