The mathematical typesetting parts of Radical Pie are now 100% feature complete. I still need to implement the drawing tools and finish a bunch of UI features. Then it'll be time for a beta release. radicalpie.com

An electronic edition of PGA Illuminated is now available here: amazon.com/dp/B0F7FZLNVD/…

Meanwhile, a user enters an emoji in a equation, and voilà. radicalpie.com

Slug version 7.4 has been released. This update includes several small feature improvements.

I read this article about software development, which I knew about because I saw Prime reacting to it: notashelf.dev/posts/curse-of… For the most part I think it is fine: a relatively young programmer is doing the healthy work of introspecting on what he should really be doing. But

I decided to downgrade from D3D12 to D3D11 in Radical Pie. D3D12 was overkill for an equation editor that's just rendering text and vector graphics (with Slug). Plus, some older GPUs can run RP just fine, but won't work with D3D12. The core rendering code shrank by 46%.

I wrote a new blog post about something I'm calling the transwedge product. It allows us to fully decompose the geometric product into discrete parts using the primitive operations of the exterior algebra. terathon.com/blog/transwedg…

There is a deep, circle jerk rot infesting peer review in particular and academia in general. And I still see people defending both as holy institutions which must not be questioned.

Generalizing to a convex polygon with n vertices, clipping against a single plane can increase the total vertex count by at most one. If you're clipping against a cube, that means the final vertex count is at most n + 6. So if you started with a triangle, then the maximum is 9.

I'm surprised to see 4K monitors still under 5% in the Valve Hardware Survey. store.steampowered.com/hwsurvey/Steam…
