Cybersecurity weather person and award winning shitposter. Shitposting is an anagram of Top Insights. You may be surprised to know I am not representing my employer here and these are not their opinions.

I have Direct Messages disabled - you can send them, but I will never receive them.

CIO by day, cybersecurity professor & Forbes Contributor by night, and a firm believer that the best ideas start with good coffee. I’m passionate about using AI, cloud tech, and leveraging system dynamics to make work (and life) a little easier.
Outside of work, I’m either reading/writing in some indie coffee house, hiking shady trails along the river, or adding to my ever-growing collection of houseplants.
I’m always learning, always leading, and always up for a good book or a new coffee house to explore.

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.
