Reference to the LKML thread:
Unpopular opinion regarding the whole Linux boot, randomness and blocking discussion:
Continuing operation without blocking when there’s not enough entropy is bad because one may generate weak cryptographic keys. However, I think the basis for Linus argument is right when he says that people regard this behavior (blocking boot) as broken.
Blocking is a usability issue and that almost always trumps security. The underlying problem is scarce entropy which should have been solved long ago...
Guess we now have fuzzers preempting CVE embargos: CVE-2019-14821 embargo got lifted because syzkaller (Linux syscall fuzzer) found and reported the same KVM bug.
as every ~6 months, I setup a small router (PC Engines APU) for our upcoming MirageOS retreat in Marrakesh... using MirageOS services where applicable: DNS, DHCP, CalDAV... \o/ -- this time with reasonable monitoring (influx + grafana) so others can enjoy and play with this in Marrakesh.. the router being our infrastructure also means the root password is empty, and everybody is invited to improve (or mess around)... I also plan to document that setup this time for real ;)
The conference was SpISA 2019: Workshop on Instruction Set Architecture Specification. The program had some very interesting talks so if this is your cup of tea, keep an eye out for slides becoming available.
Unfortunately there were no recordings apparently.
According to a talk at given by an Intel employee, Intel is working on a machine readable specification. This would be huge since it would provide an unambiguous and consistent specification of the x86 ISA. That’s the dream anyway ;)

Made my first poll on the birdsite. Obviously, I only ask easy questions about uncontroversial topics... 🤦♂️ #Brexit.
I just need ONE MORE #cccamp2019 ticket to make sure everyone in my Mexican squad who can go to camp makes it there.
Please retoot or let me know what I need to do to incentivize folks.
enjoyed this critical mass bike ride today in berlin quite a lot... 40km with 5000 people... :D i really like the organisational structure (none, more-or-less consens based where to go at every crossing); and the police being very nice and polite (this used to be quite different some 10ish years ago - where they used their batons against us)... highly recommend, every last friday in your town :D -- go and make a difference by showing that streets do not solely belong to cars :D

we now have multiple network device support in solo5 and #MirageOS \o/ :D :D

after some cleaning up (of @haesbaert awa-ssh) for a more up-to-date opam packaged world, I started to work on a ssh client implementation... before I fell asleep it was ~150 lines of code and already doing RSA key authentifcation.. let's see whether it's easy enough to open some channels and communicate as well ;) #OCaml #MirageOS
1986: Chernobyl and Northern Italy
One of the key discussion points in the HBO series “Chernobyl” is how secrecy about the accident, fallout, etc. had to be maintained by the Soviet State.
I would like to share the experience of a teen living in Northern Italy when this happened.
The first cloud arrived over Northern Italy just in time to catch heavy rainfall, indeed, the Ticino region of Switzerland, geographically beyond the barrier of the Alps and adjacent to Northern Italy was badly…
Had a most enjoyable time at Säntis Systems Summit with many interesting discussions! Learned about RISC-V, Return of the One-Time Pad and many other interesting things.
It was nice to meet up with friends and at the same time meet new people. What a great group of people together on top of Säntis!
