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 #CHERI project, where I led the early language / compiler strand of the research, and am the maintainer of the #CHERIoT 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.

There's one very important thing I would like everyone to try to remember this week, and it is that AI companies are full of shit

Only rarely do their claims actually bear scrutiny, and those are only the mildest of claims they make.

So, anthropic is claiming that their new, secret, unreleased model is hyper competent at finding computer security vulnerabilities and they're *too scared* to release it into the wild.

Except all the AI companies have been making the same hypercompetence claims about literally every avenue of knowledge work for 3+ years, and it's literally never true. So please keep in mind the highly likely possibility that this is mostly or entirely bullshit marketing meant to distract you from the absolute garbage fire that is the code base of the poster child application for "agentically" developed software

You may now resume doom scrolling. Thank you

Two good dogs this evening!

Winston, who lives in a flat nearby and is often out on the balcony. He is basically a tube of dog with a happy face on one end. When I first met him, he had the confused-but-happy face of a dog trying very hard to work out if I was his new friend or his new best friend. Today I almost talked to his human, but when I started he noticed that the scritches had stopped and tapped my leg with a paw to remind me that, in fact, I was on the pre-approved list of Winston scritchers, and this came with some obligations. And then proceeded to lean on my and make sure I didn’t get distracted.

Then Alphie, who was a toy poodle (so soft!) who I met for the time, but who was very happy to meet a new admirer.

My favourite thing about the iPad is how many almost-identical gestures do completely different things. Especially the fact that some have no undo functionality.

To be fair, this is basically my reaction to Odin too.

From what I’ve heard, he actually has no idea how one extracts oil from a snake.
