ok wow just got my first let's encrypt certificate :)
using my own udns primary and secondary server code (now supports caa as well)
and i extended ocaml-letsencrypt from maker (is he on mastodon?) to use nsupdate (+tsig) from my dns implementation mentioned above.
the certificate signing request was btw done using @yomimono ocaml-certify
that was a nice friday evening :D
While I couldn't get much out of google project zero's blog post, I find the #meltdown paper surprisingly accessible. A CS undergrad who has read about basics of CPU design (e.g. the first few chapters of Tanenbaum's "Structured Computer Organization") should be able to follow this paper! I hope anyone who designs CPUs of the future will read it.
Some understanding of CPU chache side channels will help. These have been described in e.g. cparcival's hyperthreading paper: http://www.daemonology.net/papers/cachemissing.pdf

Carlos Cardena (ccardenas@) brings initial CD-ROM/vioscsi(4) support to #OpenBSD vmm(4)/vmd(8): https://marc.info/?l=openbsd-cvs&m=151495800420938&w=2
Today I ran 'sudo usermod -G wireshark stsp' on #ubuntu.
On #OpenBSD this command adds 'stsp' to the 'wireshark' group, keeping membership in other groups intact.
On ubuntu, 'stsp' is added to the 'wireshark' group and *removed* from any other groups 🤦 The desktop crashes. Root access is now lost since 'stsp' is no longer in the 'sudo' group. I then learned about #Linux usermod's -a option, but I like #OpenBSD's -G default better.
I took a detour into recovery mode to fix up /etc/group.
Well apparently I'm early and nobody is here yet. The friendly neighbour says Tuesday's 10 o'clock meeting is more likely at 10pm than 10am 🤷
USB will be great! Finally, a single serial port spec! Say goodbye to that confusing mess of incompatible connectors!
*spends half an hour on Slack with a fellow hacker trying to figure out what kind of USB adapter they need*
