    My response to the recent Actix drama about unsafe, with a modest proposal how to hopefully make things better:

    GPU twitter: on Metal, Iris Plus 640, I'm seeing roughly 4x bandwidth for fragment shader writes to render target (~10Gpix/s) vs texure2d.write(~2.5Gpix/s). Is there a good explanation for this?

    One of the best explanations of moderately tricky geometry and math I've ever seen.

    I've generalized this to cubic Béziers, test page is up at . Question for 2d graphics Twitter: what's a good journal or conference to submit to? It feels like it's met the threshold for an academic paper.

    Recursive subdivision is not the best way to flatten quadratic Béziers to polylines. Here's a better way: . Hopefully catnip for my followers who are really into 2D graphics and math.

    Unbelievable. I've been anticipating druid being ported to smaller devices, but here somebody has actually made it work on #![no_std], running on a PineTime. This says a lot about how vibrant the Rust community is.

    I am extremely pleased to release v3.000 of Inconsolata, the first variable fonts version: There's a bit more polishing I'd like to do, but I also wanted to get this release out there so people could test it thoroughly and report issues. Enjoy!

    Getting closer to Inconsolata release. If people want to try out the font instances, that would be super helpful:

    I'm in the final stretch of making Inconsolata into a variable font. Here's a very rough (no sign of webdesign skills) tester where you can play with it:

    There's some amazing tech in here, it deserves more attention.

    The new 1password X is partly rewritten in Rust, and I'm tickled that it uses pulldown-cmark for Markdown support:

    Thanks for the kind words, and for coming to the talk. I had a lot of fun preparing it.

    The compositor (in a desktop windowing system, as a pole around which to build a UI) is evil. [This is a blog post I'm slowly writing]

    See thread for nice resources on the Euler spiral and its generalization to polynomial spirals, including an live-coding spiral animator.

    This seems like a pretty big deal - Rust is uniquely able to bridge the gap between performant systems programming and the safe, high level abstractions needed to build applications.
