It's official, two of my colleagues and I have founded a new company in software verification: Proofcraft! proofcraft.systems

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. typetheoryforall.com/2023/02/04/27-… Available at your favorite podcast manager



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

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 (Joint work between @cis_unimelb, @UNSWCOMPUTING and Proofcraft w/ coauthors @buckdotly, @tobycmurray, @lsf37 and @GernotHeiser)

Ongoing work is with @tobycmurray (@cis_unimelb) collaborating with Scott Buckley, @GernotHeiser (@UNSWCOMPUTING), and @lsf37 (Proofcraft). Relevant prior publications: 🔖 Heiser et al '20 doi.org/10.1145/342147… '19 doi.org/10.1145/331755… 🔖 Ge et al '19 doi.org/10.1145/330242…

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
