Anthropic rewrote its Messages API in Rust. Zero Rust devs on the team. Claude wrote the code. Humans wrote the plan and checked old vs new matched on real traffic. CPU dropped 40-50%. Pretty sure "never do the big rewrite" is dead advice. @katelyn_lesse on @latentspacepod

iMessage is lowkey a hack built on top of APNS. Each message is sent as a push notification to each iOS device. There’s no “iMessage backend” for receiving or listing messages. This is why they sometimes appear jumbled or missing across devices. Airlines leave a port open on their firewall for push notifs, so iMessage work as a side effect of push notifs working. WhatsApp, Messenger etc also engineered their clients to take advantage of this hole. As long as APNS is unblocked most messaging apps work. Airlines are incentivized to keep APNS unblocked because otherwise push notifications would fail for their own apps. Because it is just one persistent connection to Apple, there is no way for them to blacklist or whitelist the apps that are allowed to send or receive push notifications. Attachments fail bc they are sent as external links in the APNS bundle, but can’t be downloaded because opening the link requires more ports to be unblocked (80 and 443 usually). This happens if you buy the paid WiFi or spoof the MAC address of a whitelisted device.

sam: local inference is a terrible allocation of scarce resources “a lot of people want local inference, and somehow they assume that the problem is solved now because we have open-source models, we're going to be able to run them on our computers, and so we're not going to need all the stuff in the data centre but from a global allocation perspective, actually it's quite terrible to have everybody, like, have a bunch of the world's limited supply of DRAM sitting in their own computer and being used five percent of the time you want maximum utilisation in the cloud if you're trying to deal with this very supply-constrained environment somehow many people's intuition is the opposite of that”

Last night an AI agent performed brain surgery on a mouse. We gave it 19 gene therapy vectors in a spreadsheet, a mouse model of epilepsy, access to a motorize surgery rig with cameras and one goal: reduce seizures. It picked the drug. It picked the brain region. It derived the coordinates from three papers. Then it drove the stereotaxic arms into the brain and injected 250 nanolitres while watching the entry site through the rig camera for bleeding. A licensed vet gated every irreversible step and held a physical kill switch to stop the AI agent. Thread on what it decided, what it saw, and the moment it refused to let me override it. [Writing this on the spot out of excitement, but I've been 18hrs in front of my laptop coding and coordinating this, so keeping it brief and descriptive, more cohesive thoughts on this soon...]

‘SMILE 3’ is moving forward. David Bruckner (‘The Night House’) is set to direct with Nick Antosca (‘Verity’) writing the script. (Source: variety.com/2026/film/news/s…)
