really excited to merge this PR that enables Fontsource to build fonts from source rather than scraping all of Google Fonts if it works out, it lets us close tons of issues and even makes reaching the fabled zero issues repo a realistic goal!

The WebAssembly 3.0 spec is complete! webassembly.org/news/2025-09... This includes major features like GC, 64-bit memories, exceptions, and tail calls.

Midnight shower thought - I wonder if we could leverage the AST in tsgo and transpile the code into an equivalent Go AST? With a ready to use GC and a packed standard library for I/O, I wonder if JS->Go native could be a thing. (There’s definitely limitations, but it could be worth it)

TIL Word and Excel documents are just zip files stuffed with XML

One of the great failures of the human mind is to not value security until something breaks

When you have the urge to run a CT log but can’t justify to your company why they should fund it :p

@vite.dev and @vuejs.org creator @evanyou.me is tired of JavaScript's fragmented tooling ecosystem. He provides insight into his team's efforts to fix it. By @lorainelawson.bsky.social

We released DuckDB 1.0.0 a little over a year ago with a small easter egg. Since then, no one reported finding it, so we're revealing it: the hash of the DuckDB 1.0.0 binary starts with the duck emoji: 0x1f986 = 🦆.

We're thrilled to announce the first stable release of Oxlint - version 1.0! Our Rust-powered JavaScript/TypeScript linter delivers 50~100x faster performance than ESLint with 500+ rules and zero configuration required. Time to give it a try! voidzero.dev/posts/announ...

TypeScript excitement 😉 The "tsgo" native Go port is now available on npm as an early preview 🎉 🔷 Checker: Most projects will see error parity with v5.8 🔷 Now supports JS and JSX 🔷 LSP: Auto-completions work 🔷 Perf: 10x win persists 🔷 API: Sync access via a Node addon

Happy to say that I'll be speaking at @gophercon.com 2025 about TypeScript's port to Go! There's a lot of interesting stuff to talk about, from the effort's inception, the actual process of porting, and all of the Go stuff we learned along the way (gotchas, perf). www.gophercon.com/agenda/sessi...

TIL you can just send two requests to object storage in parallel and drop your tail latencies 📉

This is a fantastic post, categorizing transaction schemes transactional.blog/blog/2025-de...

I've been finding more time to work on OSS these days! Was able to ship out a couple new releases for my Go projects: ⭐ github.com/medama-io/me... - Added an optional tool to automatically provision SSL certificates ⭐ github.com/medama-io/go... - Added many more convenience constants and helpers

🎉 Go 1.24.2 and 1.23.8 are released! 🔒 Security: Includes a security fix for net/http (CVE-2025-22871). 🔈 Announcement: groups.google.com/g/golang-ann... 📦 Download: go.dev/dl/#go1.24.2

inspired by @harlanzw.com's cool meetup page, I added what is possibly a terrible feature to my site. - location auto-updates daily using apple shortcuts - bigdatacloud.com reverse geocodes it - stores it in @sanity.io - displays it as an emoji in header + in a line of text privacy? what privacy?

TypeScript team: rewrites compiler in Go. Go community: what do you mean your new compiler takes more than a minute to compile? Unacceptable. Dishonorable even. We are so sorry for this sub par experience. Not how we do things around here. Two days later: WIP 5x speedup. HN: why pick Go anyway?

Dang they're on top of things, beat me to filing this 😅 github.com/golang/go/is...

it has been very very amusing to see the language wars in this thread At the end of the day, I’m glad they’re porting over to anything – since they previously rejected proposals like this due to their strict dogfooding policy

Stumbled across fontsource.org today – an absolutely delightful library of self-hostable fonts for Vite-based projects Major kudos to @ayuhito.com

Fontsource v5.2.0 is out! 🎉 It adds a new @fontsource-utils/scss package 📦 This does have a few breaking changes from the old Sass import style, but is well needed for all the fixes included! 🔧

ECMAScript excitement 😉 Congrats to @nicr.dev on advancing `import defer` to Stage 3 today at TC39 🎉 This improves performance by permitting synchronous lazy-loading of modules. Only evaluation is lazy. Fetch & parse remain eager. github.com/tc39/proposa...

We are happy to announce DuckDB v1.2.0 “Histrionicus”! The new release has several usability, security and performance improvements. It has new features for the CSV and Parquet formats, as well new (opt-in) options for DuckDB's own format. Read more at duckdb.org/2025/02/05/a...

JavaScript's date object has been tricky for years, but that will change soon. The NEW Temporal API brings, 🌍 Easily handle time zones 📆 Precise date math 🕒 Parse ISO strings without errors ⌛ Durations, date ranges, and more. Start exploring 👇 developer.mozilla.org/en-US/blog/...

Wrote up a summary of my 2024 work finances. 💸 tl;dr: I took in ~$60k as an independent open source maintainer. ~$47k of that was from open source sponsorships. I'm very grateful to everyone who sponsors and/or works on sponsorship platforms. Thank you! 💚 www.joshuakgoldberg.com/blog/2024-fi...

Digging into CI data and noticed that over the last week, we've spent more time reporting to datadog about test runs than actually running tests or typecheck. The good news is that this should be easily optimizable.

I am unreasonably excited about the upcoming omitzero feature in encoding/json: tip.golang.org/doc/go1.24#e...

just cut a new release for go-useragent removing all heap allocations and making it a faster zero-alloc library strings.Builder in Go leads to at least two allocations, so replacing that with a fixed size rune buffer moves everything to the stack reducing GC pressure! github.com/medama-io/go...

New blog post covering the mysterious 10ms startup regression of Node.js on macOS, the journey of investigating the issue with various performance tools, and figuring out the fix (which also helped making the binary smaller). joyeecheung.github.io/blog/2025/01...

And you now have a very straightforward way to pitch why supporting your OSS dependencies is essential to your team and company. Tell them about the @opensourcepledge.com, and join 30 (and counting) companies that gave together 2.5M dollars to Open Source maintainers over the last year.

Most low level performance optimizations be like: How can we represent this thing in bits and only do simple math on it instead of creating actual objects.

TIL @github.com added Actions Performance Metrics Still in preview mode, here's an example: github.com/webpro-nl/kn... Docs: docs.github.com/en/actions/a...

❓Did you know you can read any Readable as a web stream in Node.js directly? No need to wrap them in Request. ✅ Use `node:stream/consumers` instead. Performant and nice.

a few months ago we migrated the fontsource.org website from fly.io to cf workers to gain some perf improvements since our api was already hosted on workers. turns out I forgot to copy an env variable over which set our robots.txt to disallow all agents blocking all indexing 🙈

I just closed go.dev/issue/54766 as fixed! Please try out the RC! 🇨🇭┳┳

I love the Fish shell writeup on their Rewrite-it-in-Rust journey. It's really nuanced: there's some good, some bad, some introspection on their own mistakes. But most importantly: they did it! 2604 commits over ~two years of work across > 200 authors. Ship ship ship! fishshell.com/blog/rustport/

One of the many reasons I love Go is how easy it is to build and containerise. However, it’s also important to ensure your production application has the smallest attack surface possible, is portable, and small in size. Let’s talk through how you might do that. Let’s see how we might build that.

feels like an improvement 🔥 (coming soon in @​nuxt/schema v3.15.1)

did a little bit of OSS maintenance the other day and I fully empathise with this. that said, I do notice things break more often in JavaScript libraries… doing cleanup in Go was actually painless in comparison.

There's a GitHub user opened 1k+ PRs in one day to update licenses to 2025

finally joined bluesky :o you may know me from github.com/fontsource/fontsource or github.com/medama-io/medama let's get in touch!
