Shout-out to seL4, this years software award winner. Still a leader on the power and possibility of proved correct software!

If you’re curious about formal methods & #seL4, this episode is a wonderful deep dive cum oral history. On a personal level it reminded me how much I miss working alongside @lsf37 every day, without whose mentorship I’d surely not have ended up in academia. Viva verified software

📢 One more episode is out! This time we talk with @lsf37 about the formally verified seL4 microkernel using Isabelle! We also talk about his PhD thesis on formally verifying a piece of the Java Virtual Machine. #6fd6bbf0" target="_blank" rel="nofollow noopener">typetheoryforall.com/2023/02/04/27-…

JFlex 1.9.0 is out: jflex.de
A little faster, all known bugs fixed, better warnings and new features. Enjoy!

@pruvisto @TaliaRinger @larsr_h With that you can build base images that contain multiple sessions that will all be available in that image.
English
@pruvisto @TaliaRinger @larsr_h That’s not quite right. Sessions and images are separate things in Isabelle. An image is just a heap dump, a session is a logical unit. You can depend on multiple sessions, but there is one designated main parent session that corresponds to an image you want to build on.

What do proof assistants outside of Coq do for package management and distribution (a la opam)? Any particularly beautiful or effective solutions to this problem?

@sproulM_ Just played around a bit asking it about seL4 and it’s just good enough to be slightly wrong. Bit scary tbh.
English
@lsf37 (it wasn't so good when I pasted in the proof state and tried to get it to make progress)
English
@sproulM_ Ah well, and there I thought AI might finally be useful for something.

The videos from the seL4 Summit 2022 @seL4Foundation are now online😀. Check out Nils's @niwist talk on fence.t, a novel RISC-V instruction that clears the processor's microarchitectural state and thus any timing dependence on execution history. youtube.com/watch?v=tLcum9…

Some good news: We've had a paper accepted to FM'23 on our formalisation of the prevention of microarchitectural timing channels by operating systems

The #seL4 #Summit is over. It was an awesome event. And it was fantastic to once again work closely with the incredible June Andronick, like in the old days. Thanks all who participated! @seL4Foundation
