Pretty surreal to see @theo covering my article! I caught it live, so can assure it was a fun watch from my point of view. 🍿 Theo also caught the fact that React Native deploys to e-ink Kindles and PlayStations, which I overlooked! Tempted to add those to the addendum now 😄

I'm making a PR to React Native Windows and was really surprised that their GitHub Copilot auto-review runs in just 1m45s. Pleasantly fast compared to Cursor BugBot

I got 21m04s of work (two completed prompts, plus one interrupted prompt) out of GPT-6 Astra Extra High before it blew through my entire 5 hour usage limit on ChatGPT Plus (25% of my weekly usage). It's clearly a very capable model, but it's rather extravagant on the Plus tier

Yesterday I attended the W3C Japan 30-year anniversary event. The guests for the panel discussion were stacked: - Satoko Takita (the "mother of the web browser") - Jun Murai (basically the Tim Berners-Lee of Japan) - Takeshi Natsuno (brought the Web to mass-market mobile devices)
