This might be one of the funniest (bad) computer jokes of all time
a trusted intermediate CA just "leaked" (the private key was 4)

Hot tip, if you want to tokenmax and make agent turns take longer, put some formal verification in your inner agent loop

I don’t think personal software will kill OSS and I think it’s very overrated. It’s super fun to jangle the keys in front of your own face and vibe code up a copy of something else that exists in this world. But truly owning it, operating it, having a vision for it kinda sucks! OSS still wins out on the a value proposition that it’s free and you can shunt those concerns off to someone else. The talking computers don’t actually know exactly what individual people want and most people don’t feel like just living with whatever an agent confabulated as a design and architecture. The future for OSS probably involves a token market where you can yield some tokens to allow a maintainer group make the right decisions for you.

Bo Nix is the John Elway of Tim Tebows and it’s beautiful
Truly disgusting player

More seriously, Nix has that fourth quarter dog in him. Stats don’t show that, but his winning record does

Introducing my new side project - Fai. github.com/Krzysztof-Cieslak… It’s a functional programming language with which I try to explore how we can design better “classical” software engineering tools specifically for AI agents. A couple of design choices I've made are described ⬇️

What should we improve in the GitHub Copilot app?

So far Argon really does seem the best at absorbing a bunch of text and turning into a rough draft of a doc with decent writing style. But man, so much steering still. AI assisted doc writing is like working with the first coding agents when they came out

Like you tell it no fluff, grammar of a fifth grader, ELI5, simplify, keep it terse, brevity, all the intent-based keywords… …and every one of these damn tensor swamp pits just jumps at the bit to slop you up some extra wordy bullshit

Cursor’s de-slop doesn’t work, none of the skills I try work, I dump all my own writing in as examples and it doesn’t work, it’s still just so mid! But Argon definitely feels like it made progress over the rest I think

New on our Engineering blog: Creating in-house source control. In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale. Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

Has ChatGPT on iOS gotten super slow for people? iPhone 15 not on low power mode so I don't think it's my phone. Takes ~3-5s to load in the sidebar the convo I started on desktop and got a notification for on the phone. Then noticeable lag as the keyboard popped up.
