and i extended ocaml-letsencrypt from maker (is he on mastodon?) to use nsupdate (+tsig) from my dns implementation mentioned above.

#openbsd up and running on an old PowerBook g4. Because of, ya know, current events.
Tube patched and nasty tiny piece of glass removed from tire. If only patching CPUs was this simple... https://mastodon.social/media/P4kLnVpNex3hKvwCxoI
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
Disadvantage of not working from home: Bicycle tire punctures cost a lot of time and money... https://mastodon.social/media/UbdH4HNyTXJNYknKjBY
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.
Starting a new job today at Sysmocom. Curious to see what's waiting for me 🙂 https://mastodon.social/media/q0GirPvhso-5dY7qbIQ
