🌌 In space, two pieces of metal can fuse together without heat, glue, or welding equipment. And the reason is stranger than you might think.
On Earth, two metal objects can touch without becoming one. But in the vacuum of space, under the right conditions, something remarkable can happen: **cold welding.**
Metal surfaces are usually covered with thin layers of oxide, dirt, and other contaminants that prevent their atoms from bonding directly. When two exceptionally clean metal surfaces come into contact in a vacuum, their atoms can form bonds across the boundary, joining the pieces together.
And this is not just a scientific curiosity. NASA's Galileo spacecraft experienced problems when its high-gain antenna failed to fully deploy in 1991. Cold welding was considered one possible explanation for the jammed mechanism, although the exact cause was not conclusively established.
Today, spacecraft engineers carefully design moving parts to reduce this risk using protective coatings, lubricants, and other techniques.
**Imagine a machine in space whose metal parts accidentally become one solid piece—not because they melted, but because their atoms bonded together.**
The universe follows some rules that seem almost impossible until science explains them.

The problem is not people being uneducated.
The problem is that people are educated just enough to believe what they have been taught, and not educated enough to question anything from what they have been taught.

Banks started blocking AI agents this week. The builders answered with robot arms.
These are racks of real phones, each with a mechanical arm tapping the screen like a human finger.
This is PhoneUse, built by Abdulla Ababakre. It gives an AI agent a phone of its own.
Most apps have no API for agents, and the rest are learning to block them. A real tap on a real phone leaves nothing for the app to flag.
The direction is clear: if the software door closes, agents will walk in through the front door.

Well… yeah.
I discovered long ago that non-tech folks really don’t care much about computers and computer-related things other than to use them to do work perhaps.
🔒💢 Le DNS public gratuit de Mullvad ferme le 2 novembre... Et le 24, Quad9 quitte la France
En 3 semaines les Français perdent deux DNS gratuits pensés pour la vie privée
La plupart des tutos vont te conseiller Cloudflare ou Google. Deux géants américains qui appliquent déjà en France les blocages DNS ordonnés par la justice
Et surtout ne reviens pas au DNS de ton opérateur... il voit chaque site que tu visites
Ce que tu peux faire...
➡️ Sur Android : Paramètres.. Réseau.. DNS privé.. dns.digitale-gesellschaft .ch (un DNS chiffré géré par une association suisse. C'est un exemple parmi d'autres)
➡️ Sur PC : dans Firefox ou Brave, active le DNS sécurisé avec un fournisseur personnalisé : https://dns.digitale-gesellschaft .ch/dns-query
➡️ Pour bloquer le phishing ajoute plutôt uBlock Origin dans ton navigateur
Le plus solide reste un VPN sans logs audité, comme Mullvad VPN (le VPN continue) ou @ProtonVPN il chiffre tout ton trafic pas seulement le DNS
Bref... Ils peuvent forcer un DNS à partir. Ils ne peuvent pas t'empêcher de chiffrer !
the gemini app experience is honestly the worst. what is google even doing?
i literally asked a simple question: “hey gemini, tell me why you are the best.”
it took 4 minutes to answer. and this isn't a one-time thing. almost every time i use the app, it takes way too long to respond, even to simple queries.
why aren't they fixing this? the app is nowhere near chatgpt or claude in terms of speed and overall user experience.
