  1. #Java crash bug on #macOS 14.4 is in my wheelhouse (resilience.)

    Root cause seems to be they changed what signal the OS sends to a process when certain kind of mem access is attempted

    In the case in question the kernel previously delivered a SIGBUS or #SIGSEGV

    If you've ever heard of a program crashing via a so-called #segfault it means the process received a #SEGV sig, it did NOT handle it explicitly (& robustly) & the default behavior was to crash

    now they SIGKILL it! *cannot* be handled!

  2. Have you ever wondered why segmentation faults are abbreviated "SIGSEGV" in Linux?

    Where does the "V" come from? Shouldn't it be "SIGSEGF" instead? ("F" for Fault - not "Vault" 😉)

    David Wragg and Marek Majkowski have a bit of UNIX history for you!
