@bjhomer The kind of love we pour in the line of business Iโ€™m in doesnโ€™t belong in release notes. That would completely defeat the anxious bindiffing and slow incremental discovery of which techniques died, which survived and which are on the chopping block.

We're hosting an event focused on security on March 5. We're going to present the technologies that we use to make iOS the most secure platform in the world. Sessions are led by Apple engineers working directly on platform security and security tools. developer.apple.com/events/view/D4โ€ฆ

I have often stated that well-implemented memory tagging will be a game changer for memory corruptions. And it seems that with the next iPhone it's finally here: security.apple.com/blog/memory-inโ€ฆ

Amazing work! Iโ€™m surprised to see Apple managed to get synchronous tag checking in production. I wouldnโ€™t have bet on that given the performance constraints. Getting the sign off to get so much security-specific silicon is also a huge accomplishment.

First I optimized CPU, then memory, now I'm onto the renderers (Metal first). Scrolling Neovim now sustains ~175fps easily (vsync off of course). More room for improvement, but this is already best-in-class (I can't find a terminal at the moment that does better on macOS). The road to get here was long. To quote @thorstenball I've been "moving the chess pieces into place over the past few months." I'll write about it in a devlog, eventually. And, people will inevitably say "high fps doesn't matter for a terminal." And yeah, maybe, but what's the fun in that. My answer to "why" is "because I can!" (Disclaimer: I use the Japanese bible as a sort of stress test for certain IO tests. I'm not religious and there isn't meant to be any sort of hidden message in this.)

โ€œIt is much easier to consider genocide in the past tense rather than contend with it in the present. Legal scholars tend to sharpen their pens after the smell of death has dissipated and moral clarity is no longer urgent.โ€
The Nation@thenation

The Harvard Law Review refused to run this piece about genocide in Gaza. The piece was nearing publication when the journal decided against publishing it. You can read the article here: bit.ly/47ENL1W
