Rust is so amazing. Had a weird bug happen yesterday in our OT protocol, and within 2 minutes i knew what the deal was: a usize instead of u32 in our protocol (32bit vs 64bit is different). When Rust does something unexpected the places it can be wrong are tiny.

I'm not a big fan of customizing anything, from code editors to OS settings. All your customisation becomes a workload you drag along every time you reinstall / update.

Owyeah! This is great. Google is stepping onto webGL+wasm bigtime. Looks like the technologies we depend on are hereby solid bedrock.

I think @GoogleDocs is the first high-profile mainstream web app that I've seen announce a move away from the DOM entirely, to an HTML canvas. That also opens the door to WebAssembly and WebGL... Super excited to try the difference.

It's so amazing to see our final path to product appear. We have an amazing UI design (done in figma) i will share soon. Should make clear what we are building :)
