"whois is a kind of repository". Awfully wrong, of course, but I noticed that .lu don't give a lot of details via whois, even, for corporations (try whois microsoft.lu)#LuxembourgInternetDays

Discussion about notification. Even when you get an email address, people don't reply to it / do nothing. One of the big frustrations in cybersecurity.#LuxembourgInternetDays(On the other hand, many reports are spurious, ask @bagder )

@bortzmeyer This makes me wonder, how "Expires" plays a role regarding PGP keys? Sure, the link might be the same, but the key('s expiry) could be updated.For instancesecurity,txt:> Expires: 2030-01-01T00:00:00Zlinked PGP key (at time of writing):> pub rsa4096 2014-02-08 [SC] [expires: 2027-09-16]

@bortzmeyer Nono, obviously the information is still valid, and technically the *link* to the PGP key is also still valid, even after an update.

Official welcome speeches, now, at #LuxembourgIntenetDaysFirst, the chairman of the local exchange point https://www.lu-cix.lu/ insisting on the role of "open source" [sic] sofwtare in sovereignty (example of Matrix, which is not software, by the way, but a protocol).Then, a remote video from European commission '"Europe has three million open source developers", it seems a lot, I'm not sure I heard correctly). "We need more AI.'.

Alain Courson, an insurance broker, on cybersecurity insurance at #LuxembourgInternetDays : "many companies are underinsured" I know next to nothing about financial issues in cybersecurity so it is interesting.What is *excluded* from insurance claims: gross negligence,failure to maintain security hygiene, missing backups... (It seems to me it will exclude most organisations.)

@adulau Et l'argument du spam cité par l'orateur, n'est pas très convaincant. Le serveur publlc que j'utilise ne voit guère de spam. En fait, l'absence de spam montre que Matrix n'est pas largement adopté.
