I’ve worked with tinygrad at multiple points over the past couple of years. It’s a very cool tensor library with autograd features and support for a variety of backends, and I appreciate how it makes me feel in control of the code that’s running on my GPU rather than pushing buttons on the outside of a black box wrapped with 800k lines of C++. One thing I wanted to try out with it was model export.

I regularly use Graphviz to generate… graph visualizations. Since my website and blog are all dark-themed, I usually want to set it up so that the generated SVG is dark-themed as well. Here’s the basic config I use to make graphviz produce outputs with dark backgrounds and light content: digraph G { bgcolor="#181818"; node [ fontcolor = "#e6e6e6", style = filled, color = "#e6e6e6", fillcolor = "#333333" ] edge [ color = "#e6e6e6", fontcolor = "#e6e6e6" ] # The rest of your code goes here.

Recently when working with the regl WebGL wrapper library, I encountered a weird error that I didn’t understand the cause of: (regl) invalid dynamic attribute "position" in command I checked my code, and I was indeed passing a position attribute and the data array I was using to construct the buffer looked correct. The error also happened intermittently, happening after my application hot-reloaded. The Cause It turns out that I had accidentally created two regl instances and was trying to use buffers allocated on one with commands created on a different one.

I was working on a new SvelteKit project with Svelte 5 recently, and I kept getting an error that prevented anything from loading in the browser: [vite] Pre-transform error: Failed to load url __SERVER__/internal.js (resolved id: /Users/casey/osu-embeddings/frontend/.svelte-kit/generated/server/internal.js) in /Users/casey/osu-embeddings/frontend/node_modules/@sveltejs/kit/src/runtime/server/index.js. Does the file exist?

The Problem I recently created a new SvelteKit project using the Svelte 5 preview and kept getting an error at the beginning of every Svelte component: The error was e.children.findLastIndex is not a function (svelte). It was showing up even on the basic SvelteKit skeleton starter project as soon as I added a <style></style> block. The Fix I looked around online, and I didn’t see anyone having this problem. This led me to believe that it was likely an issue with my local environment or configuration.

I run self-hosted Plausible analytics to keep track of how many people are visiting my various websites and web apps. I’m largely very happy with it - it gives me all of the info I need with only a miniscule JS payload, no cookies or other invasive tracking, and full control over the data. However, recently I’ve been running into an issue with fake/bogus traffic getting submitted for my personal homepage.

For a new project at my dayjob, I’ve had the opportunity to try out sea-orm for the database layer. In the past, I’ve tried out other Rust SQL solutions including diesel and sqlx, so I have some context to compare this one to. At a high level, sea-orm provides a fully-featured solution for managing your database setup in Rust. It provides a framework and CLI for setting up and maintaining migrations, code-gen’ing entities and relations, and writing + running queries.

I recently received a bug report on a library I built - three-good-godrays - which implements screen-space raymarched godrays for Three.JS as a pass for the pmndrs postprocessing library. One of the problems pointed out was that colors seemed washed out/desaturated when my pass was used, even when the pass wasn’t rendering any godrays. Here’s how things look by default without the effect (and are supposed to look with it on):

For a long time - at least a couple of years - I’ve been cursed with an issue on my KDE Plasma Linux desktop where my PgUp key doesn’t work. Instead of scrolling up in my terminal or editor, it pops open a menu with the title “Select to paste” and a listing of my most recent clipboard entries: I tried briefly a couple of times to fix this and get my page up to work again but to no avail.

I was recently working on speeding up a MIDI editor UI written in PIXI.JS which is part of my web synth project. The UI is fairly simple itself, but it needs to be efficient in order to render potentially thousands+ notes on the screen at once. Here’s what the MIDI editor UI looks like: As I mentioned, I built this whole UI with Pixi.JS (except for the toolbar which is vanilla HTML/CSS/React).
