I just learned what eBPF is from a technical perspective. A superpower for the Linux Kernel.
Honestly, it would be neat if potential users of kernel features could e.g., answer with: Used-by: systemd Supported-by: Bla Blu <[email protected]>

Today @kavehrazavi and I are finally allowed to talk about #Retbleed. In 2018, #SpectreV2 was fixed by replacing indirect jumps with returns. But, returns can be poisoned like indirect jumps, throwing us us back to 2018 again. Paper, demo, addendum, code @ comsec.ethz.ch/retbleed
Thank you so much for attending the talk!

A debugging technique I've been perfecting recently: when it's late at night and I've been banging my head on some bug (but have my mind fully wrapped around the symptoms), go to sleep. In the morning, usually solve it within 15 minutes. Subconscious really knows what it's doing.
