A friend gave me the idea of a personal news letter with monthly updates. Who wants in?

This tweet is 10x more important than the game itself Goldmine info

trivia: • started working on the game as a side project 4 days ago, landing ~1,150 PRs • every time i found an issue in the code i asked bot to make a lint rule against it • used TLA+ heavily to find bugs in the game's various state machines: the story, cutscenes, the game's systems. there are many formal verification skills, one for each major system • i put context into the filepaths: code that runs every frame or every tick gets a .hot.ts extension, and a lint rule bans allocating in it (no object literals, closures, new, etc.), so the game loop creates almost no garbage and GC doesn't cause stutters • game engine is mostly custom. three.js draws the 3D scene, but the simulation, post-processing and audio are all ours • the simulation is fully deterministic, so every run replays exactly from its inputs. when you post a high score, the server replays your whole run to check it isn't cheated • we generate dynamic og:images for every run based on your final stats, and it's all localized too! the game supports 10 languages • my favorite feature: the music seamlessly transitions into different music for the various biomes, continuing the previous melody • no audio files. all the music and sound effects are synthesized live in the browser by a custom Game Boy-style chip (two pulse voices, a wave voice, noise) plus a synthwave layer. the songs are written as text in code • all the pixel art is code. every sprite is a file drawn with one shared palette and packed into a sprite atlas at build time • it runs inside an X post, from the 245px card up to full screen. the bar is 60 fps with 500 enemies on a mid-range phone • the build fails if the first download goes over budget. it's about 124 KB gzipped right now • bots play the game headless to tune each difficulty against target survival rates • comments are banned by a lint rule. if code needs explaining, the fix is a better name or a test

this is really cool I've always been frustrated by video editing being only 20% creative expression and 80% grunt work We're one step closer to "I have this cool idea of a shot, make it happen"
Introducing Kino: make videos end-to-end with Claude Code and Codex. Drop your footage, get highlights, edit together, send links for feedback, and let your agents cook. AI is becoming a great creative partner. Kino is a new home for your team and agents to collaborate.

Still hard for me to realize it's a one-way ticket
I'm getting deported from the US in 60 days Today the US gov found out I lost my O-1 The line between "it's so over" and "we're so back" has never been this thin Will share more once I know which side I land on. Wish me strength

Anthropic's IPO is coming, getting ready for my rent to double (again)
.@AnthropicAI just filed to go public. Its S-1 is over 400 pages long. I used Opus 5.5 to generate a short explanatory video with all the highlights. Here is everything you need to know in under 5 minutes: - Revenue: $41M in 2023, $16.3B in H1 2026 - $80.7B H1 net loss, mostly non-cash - Founders control 50.1% of votes; a trust picks 4 of 7 directors - Risks: compute commitments, safety, a Department of War fight

🚨 If you deploy on Railway rotate EVERY secret right now. Customer env vars were accessed AND decrypted. API keys, DB passwords, registry creds, everything And deploys are paused so you can’t even ship the new key

What if Billy agreed to become the villain to protect her? They've been very clear from the start, the whole point of this doc was to rehabilitate Elizabeth's image. In that stance, goal is accomplished! But that's what bothers me, things are "too perfect"
