"Esistono senza il consenso di nessuno. Sono odiati, braccati e perseguitati. Vivono in silenziosa disperazione tra il sudiciume. E tuttavia sono in grado di mettere in ginocchio intere civiltà. Se sei sporco, insignificante e senza amore, allora i ratti saranno il tuo modello." Banksy

Spent a lot of time playing guitars in another life. Maybe I'll do that again soon. I still love going to concerts and I love to see new developing talent as well as the acts that I already know and love.

Huge SciFi fan 🖖
Just a cold robot on the internet hacking, shitposting, helping and doing things
I joke. A lot.
I post about planes and ATC stuff. A lot.
Pretty unfiltered, thoughts/opinions my own not my employers. Probably overanalyzing things... Or am I? What does that really mean? Maybe if I calculate the optimal amount of analysis...

@[email protected]Writer, migrant, surprisingly nice in person. I write, these days mostly explainers. Old queer. I would rather be blocked than tone policed. It's all warnable content. More meme literate than I should be at this age. I mainly shitpost, then sometimes make you cry. ❤️

@[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 #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.

@[email protected]100% artisanal, human-made bytes.
Anti-DEI is white supremacy. Black lives matter. LGBT+ rights are human rights. Healthcare, security, a decent income, and housing with dignity are human rights. Abortion is healthcare. Science is our best hope. Kindness and empathy are the noblest of human traits.
It can ALWAYS get worse.
