The room empties.

Side note: according to an unscientific survey done by an amateur observer, there are not many women at FOSDEM.

@bortzmeyer I'm not there

@Natouille You would increase the percentage of women by a fair amount.

@bortzmeyer mais j'ai pas bien compris, la salle s'est vidée à l'annonce du sujet ?

@bortzmeyer which is a pity, because we're all standing on their giant historic shoulders.

@bortzmeyer The room emptying is the problem.

"Computer was a job" (once upon a time, computations were done by hand).

DNS for I2P: Distributed Network without Central Authority by Konrad Bächler

I2P is an overlay network, adding confidentiality and anonymity

Why changing? Because elliptic curves are shorter and safer.

@jeanmimi Also, no post-quantum algorithm is standardized yet.

Bootstrapping time on OpenBSD by Otto Moerbeek

You need correct time to validate DNSSEC signatures but you need DNSSEC to check the name of the NTP server...

#FOSDEM

bortzmeyer, 4 months ago

Solution: if #DNSSEC signatures don't validate, retry without DNSSEC validation...

Once time is set, retry with validation always on.

gertvdijk, 4 months ago

@bortzmeyer Well, using NTPsec you need a somewhat correct time too, in order to validate the certificate.🤷

I guess the best and most secure option is to provide a manual approximate time confirmation by the human.

(btw your posts seem to be marked as French?)

bortzmeyer, 4 months ago

@gertvdijk I don't even where where to find the language of a toot. Where it is displayed?
(Anyway, for this one, the language in the edit widget is clearly "EN".)

gertvdijk, 4 months ago

@bortzmeyer Not sure where it's displayed in any of the Mastodon clients you're using, but on your original server it's rendered with lang="fr" like in the screenshot below (HTML), so my browser hints to translate from French and when I reply in Elk it's going to select French by default.
