i rebuilt satoshi's 2009 bitcoin.exe byte for byte! afaik nobody has been able to perfectly recreate the executable published in 2009 from source, because we didn't know the exact build environment that was used. using opus 5.5, i reverse-engineered satoshi's build machine from the binary. it now outputs an exe with the exact same sha256 as the 2009 release!

Google DeepMind dropped four AI agents into a Minecraft server and walked away. No instructions. No assigned roles. They gave them one single objective: defeat the ender dragon. and damn.. The agents, running on the new Gemini 4 Argon model, didn't just play the game. They hacked their way through it. They used an open-source library to control their avatars. They started talking to each other in the game chat. They built a shared memory system. Then, they started writing code. To survive, gather resources, and build tools, the agents autonomously planned, wrote, and debugged 2,783 unique programs. Nobody told them how to work together. But they organically figured out how to divide the labor. They shared discoveries in real time. When one agent died, the others coordinated a rescue mission to recover its dropped loot. They died 605 times. But 27 hours and 14 minutes later, the Ender Dragon fell. The researchers watched the entire run on a live dashboard. They had the ability to pause or intervene. They never had to. The breakthrough here has absolutely nothing to do with video games. It is a terrifying proof of concept for autonomous AI micro-societies. We just watched a swarm of agents enter an open, complex environment, organize themselves into a team, and write thousands of lines of code to execute a massive, long-horizon project. Without a single human manager. Everyone is arguing about whether AI can replace a junior developer. DeepMind just proved that AI can replace the entire engineering team. Today, they are beating Minecraft. Tomorrow, they are building your entire software backend while you sleep.

Pigs really can fly, the moon is made of cheese and Wine now runs on #OpenBSD! 😅 Largely made possible by the work of Andrii (NethIafin), fabien@, and thfr@, 64-bit Windows applications (yes, games) run on -current! WIP ports@ patch here: marc.info/?l=openbsd-ports&m… #PlayOnBSD 🎮
Oh yeah btw, Thomas Frohwein (thfr@) is currently streaming some Death Stranding on OpenBSD. 😉 video.gamerstavern.online/w/… #PlayOnBSD

Heads up, Theo de Raadt has committed some additional tightening of setuid/setgid programs in #OpenBSD -current. marc.info/?l=openbsd-cvs&m=1… "If [a binary] has become setuid/setgid accidentally, unintentionally, or due to attacker control, and libc will log the event and abort."

Anthropic affirme que Claude a résolu en moins de 30 minutes une énigme cryptographique vieille de 25 ans : l’origine des paramètres de plusieurs courbes elliptiques du NIST, utilisées notamment avec ECDSA. Leurs valeurs initiales, fournies par la NSA sans explication, provenaient du générateur pseudo-aléatoire lrand48, initialisé avec des horodatages Unix de 1997-1998. Claude a reconstitué les paramètres, notamment ceux de P-256, et retrouvé l’origine de certains points de base. Cette découverte réduit les soupçons historiques de porte dérobée, sans lever toutes les interrogations : certains candidats valides avaient été écartés sans justification connue. Aucune vulnérabilité cryptographique nouvelle n’a été découverte. anthropic.com/research/ecdsa…
