Le Top 3 des pays comprend les États-Unis avec 161 supercalculateurs, le Japon avec 44 et l’Allemagne avec 41. La France est cinquième avec 21 machines, juste derrière la Chine qui occupe la quatrième place. Avec seulement 31 machines référencées, la Chine est tout de même 2ᵉ en puissance cumulée. C’est grâce à son supercalculateur LineShine, qui dépasse à lui seul le total des autres pays, sauf les États-Unis.

Le supercalculateur chinois LineShine à une puissance de calcul de 2.198 ExaFLOPS.

Azure is also not enough for Copilot, so Microsoft turns to the compute of AWS.

So it must be that a key ingredient to blogging is simple: have a willingness to state something that seems obvious to you but nobody else is saying it.

Rappel qu'il faut faire attention à son matériel aussi.

It is based on Nostr.

Encore un kudo pour Fabrice Bellard, cette fois de John Carmack.

That's a way

The TL;DR is that iroh is a library and an architectural pattern to establish peer-to-peer QUIC connections between machines, even if they are behind routers (NAT gateways). It's not a replacement for WireGuard, HTTPS or BitTorrent, instead, it's a building block that you can use to build applications on top of it, but you need to bring your own application protocol and business logic. It's just a very dumb, very reliable pipe between 2 machines anywhere in the world.

Instead of building over UDP, the project builds over QUIC (that is over UDP).

Concepts:

• Endpoint: base unit of iroh. Two endpoints can establish a connection.
• Address: instead of IP addresses, endpoints have addresses that are Ed25519 signing keys.
• Connection: a QUIC connection between 2 endpoints. The connection use QUIC multipath extension, so the connection can flow through multiple pyssical paths.
• Relays: help endpoints punch holes through NATs and relay traffic when it's not possible. They allow to be internet-reachable. The default is the public relays provided by the N0 company, but a relay can be hosted and use privately.
• Discovery / Lookup: through DNS and pkarr signed packets to map an Ed25519 key to IP addresses.
• Transport: over UDP and QUIC handles the reliability and encryption. The transport can be carried over Bluetooth, Tor, radio or serial.
• protocol: application level communication (advertised in TLS' ALPN field of QUIC). A few are provided by iroh's team such as Blobs, RPC, HTTP/3

A perfect timing because:

• there is a growing sentiment against big tech and the US era of cooperation's end. Thus some are turning to build open and decentralized solutions.
• the invasion of Ukraine and industrial advances in China have revealed to the world the incredible leverage offered by cheap drones and robots. There is an area of semi-autonomous machines that need to communicate over heterogenous physical networks (radio, satellite, Wifi, ...) which is completely different that the traditional everything-over-internet (IP) model.

Current limitations of Iroh:

• rebrand to "P2P made easy" instead of "IP addresses break, dial keys instead"
• less bloated public API
• easier integration with application-layer protocols (plug-and-play HTTP/3)
• advanced routing and relay-to-relay communication.

C'est une bonne nouvelle.

wtf

Note it's similar to microformat in HTML.

PeerWeb is a revolutionary way to host and share websites using WebTorrent technology. Instead of relying on centralized servers, websites are distributed across a peer-to-peer network, making them censorship-resistant and always available. 🌍✨

Un mauvais pressentiment: un mélange d'effet d'annonce pour dire qu'on fait quelque chose, mêlé à une solution technologique venant de politiques. Cela finit rarement bien.
