🎉 Applications for the Sovereign Tech Fellowship are officially open! What’s new? For the first time, community managers, and technical writers can apply alongside open source maintainers until April 6, 2026, to become Fellows.

Graphic reading “Applications Open! Sovereign Tech Fellowship” above a photo of five smiling people standing arm in arm, wearing matching black “Sovereign Tech Fellowship” hoodies. The text overlay states that the fellowship is open to FOSS maintainers, community managers, and tech writers, with applications due April 6th, 2026 at 11:59 PM (CET), and mentions freelance and employment options as well as flexible working hours.

@cwilso.bsky.social Hey Chris, wanted to drop a note to say thanks for your Web Audio writeups! I’ve been running into them a lot this past month. ❤️

Feedback and bug reports welcome! In particular, I haven't been able to test on many platforms yet. All desktop and mobile devices _should_ be supported, but testing on Linux and Android is particularly needed.

Because I've just recently submitted the plugin, review and approval will take a while yet, and it won't appear in the Community Plugins list until then. If you're interested in beta testing in the meantime, the plugin can be installed with the Beta Reviewers Auto-update Tool (BRAT) today.

I really enjoy @obsidian.md for note-taking. But, I need some audio recording features that are missing from the app today... so I'm sharing a new "Field Recorder" plugin adding those features: - mic selection - quality settings - waveform/clipping viz - ... github.com/donmccurdy/o...

Surfel-based global illumination on the web

“Surfel-based global illumination on the web, using three.js and WebGPU.” So much good stuff here by @juretriglav.bsky.social — demo! interactive illustrations! source code! A deep dive but clearly explained, fun, and worth the time. juretriglav.si/surfel-based...

juretriglav.si

Can we use WebGPU to compute real-time global illumination with surface patches called surfels? Does it look good enough? Is it fast enough? And can we finally construct viable compute-heavy rendering...

Really worthwhile reading from @icastano.bsky.social! If you're building with WebGPU, spark.js gives you new choices for texture compression that weren't possible with WebGL. Also, I need to update my older blog post. 😅

I’m not sure! I don’t see why not, but I’m also not familiar with when to choose the newer codecs here. For “official” support a bitstream specification would probably need to be written.

I built this little tool to optimize and re-export GLTF/GLB assets to GPU-compressed KTX2. It runs entirely client-side/in-browser. You can fiddle with the parameters, compare the before/after, and export to GLB. Try it here: gltf-optimizer.simondev.io #threejs #gamedev

3/ I'd been hoping Affinity Serif would make a competitor to Lightroom, but... that no longer looks like a possibility.

2/ I like the idea of managing my RAW photos as normal files, and presumably building an Obsidian plugin to handle RAW preview and the (intentionally very limited) kinds of edits I'd want. But not obvious to me whether Obsidian is a reasonable foundation for that purpose.

I hadn't! I like the design and direction. Security is the main barrier for me... just a mostly-arbitrary hunch that a web browser needs at least one "security person" on payroll. 😥 Otherwise, I'd love to try Horse Browser too!

3/ With all that done, though, it works great! Enjoying the tab-stacking feature. And it's nice to be using a browser with healthier incentives again.

2/ ... I've been using Vivaldi the past few weeks, and I think that's going to be the move. In contrast to Arc: with Vivaldi I did have to change a fair number of default settings to get comfortable. Move tabs to the sidebar, update some hotkeys, disable the page-changes-sidebar-color thing.

100

I've used Arc (web browser) for the past few years, and it's good... but for software as security-critical as a browser, I don't love that it's really a side project for a VC-backed AI startup at this point. Writing on the wall and all that. So... 1/

Feature Request: Generating both dev and prod builds in library mode · Issue #1814 · vitejs/vite

Thanks! I realize my complaint above was vague, and no pressure to address this, but just in case it's helpful: the most recent issue that blocked me from using Vite's (current) library mode was related to sourcemaps: github.com/vitejs/vite/...

Is your feature request related to a problem? Please describe. I'm building a library and I want to generate output similar to what popular libraries like React and Vue do: esm + cjs/umd builds for...

I didn't realize `deno bundle` existed! That's very interesting option, thanks, I'll need to try this out. :)

Test runner | Node.js v25.0.0 Documentation

Node.js v20+ test runner could replace the unit testing dependency tree, too: nodejs.org/api/test.html

Vite+ (source-available, free for OSS) would presumably do all of that in one dependency? Though I haven't found Vite (have not tried Vite+) to be as good for bundling libraries as for building applications, so far.

Currently I'm using: biome, ava, c8, microbundle, and typescript. But even that short list gets a pretty regular stream of small updates and dependabot 'vulnerabilities' requiring updates across various repositories.

Garrett Johnson @gkjohnson.bsky.social · 01/10/2025

What's the minimum feasible number transitive dependencies for maintaining and publishing a small JavaScript library with types? Assume: unit tests, bundle .ts sources to .js and .d.ts, and maybe shared lint-and-format settings.
