For those who don't know, #Netnod manages a #DNS root server, a big IXP (Internet exckange point), secure time distribuition (an important thing for Netnod)... It's one of the organizations that make the Internet run.

80 PoP for the #Netnod #DNS anycast network.

Now, the first talk" Artificial Intelligence is really good for the environment?" (Bill Gates said yes.)

#Netnod

We often talk about electricty production but, in many countries, distribution is the bottleneck. many grids are overloaded.

#Netnod

An example of an AI data center: xAI in Memphis. 100,000 H100 GPUs (150 MW).
Some power provided by "Solar turbines" (which are not solar at all, it is the name of the company)
The local electricity company agreed to provide more, if they receive public money for that.

Basically, it is not clear they'll manage to get as much electricity.

#Netnod

"Nuclear seems the perfect solution to power AI data centers"

But delays and costs have a bad habit of slipping out of control.

Subcontract to Rosatom?

#Netnod

"When I was a child [the speaker has a grey beard], nuclear fusion was 40 years in the future. It still is."

#Netnod

What about #SMR (Small Nuclear Reactors)? Have your own nuclear reactor in your backyard!

You can already buy one from russian or chinese companies. Or Nuscale in the USA. Others are in the pipeline.

OK, what is the hashtag for the #Netnod meeting?

PS: the password of the Wifi is great.

Designing a data center for AI, by Nokia. Connecting GPUs: the pattern of traffic is different than ordinary traffic (more bursty, with long perios of network rest, when the GPU "think").

Despite "common knowledge", Ethernet works as well as InfiniBand here.

Now, #football "Evaluation of the impact of #UEFA Champions League Wednesday matches on Internet traffic at MINAP and NAMEX" by Gianluca Sironi. "Football is a religion"

@tounch Omnipollo, Stockholm.

Vous n'allez pas me croire mais le truc rose est une bière.

Elle est nommée Pleroma, ce qui est cool pour le fédivers.

J'ai mis du temps à comprendre la blague.

Il n'y a clairement pas assez de photos de poules sur le fédivers.

@geb @shaft Heu, réussir-en.fr est utile, le site Web a du contenu et il est utilisé en prod'

Et, contrairement à celui de l'Académie, le serveur HTTP ne redirige pas vers une version US-ASCII.

On a même des CVE sur des éditeurs de texte, de nos jours.

Hop, en route pour la finale-pas-vraiment-finale de « Ma thèse en 180 secondes » https://mt180.fr/evenements/finale-sorbonne-universite/

On attend. Mais on a un bel amphi. Et le Wifi marche. Mais pas l'envoi de photos. Problème de leur réseau ou de mon instance fédivers ? Ou bien complot des gens de l'accessibilité ?

Je ne peux même pas passer sur Twitter à la place, il est tout cassé.
