Just cut another release for modern-tar.

I’ve been benchmarking it a bunch and it seems like we’re the fastest Node.js tar library on all benchmarks.

Especially in a big way for many small files which are typical for node_modules like directories 🚀

here's what the @e18e.dev community has been upto for the last couple of months!

huge thanks to everyone involved 🎉 much more to come very soon, and we have a roadmap of some super useful tools in the works

I’ve read your blog posts many on sustaining yourself as a FT OSS developer which was inspiring, but alas you deserve more. Congrats!

One of the more awesome blog posts by the Go team that simplified a not so simple topic really well!

Cloudflare investigated performance benchmark results for Workers, uncovering and fixing issues, making Workers faster for all customers.

84 million requests a second means even rare bugs appear often. We'll reveal how we discovered a race condition in the Go arm64 compiler and got it fixed. https://cfl.re/3WrpKrB

New architecture makes a centralised interface that only accepts Uint8Array chunks which allows us to skip converting between streams entirely 👾

Released v0.4.0 of modern-tar today! Huge performance improvements and a new architecture.

We originally converted Web Streams into Node Streams to make maintaining cross compatibility manageable… but synchronising those two felt very incomplete and was prone to so so many race conditions 👾

The world depends on Open Source software

Fun little Go compiler CL merged today: go.dev/cl/706655

Uninlined generic functions have a "dict" arg, since Go generics are neither erased nor monomorphized, but instead instantiated for each "GC shape" (e.g. T=*int and T=*float64 get the same code, but T=int32 and T=int64 do not).

It’s hard to express how I love working with Go in my day job and wouldn’t want anything else, but could not say the same for JavaScript.

But I absolutely enjoy working with JavaScript as a hobby, whilst Go feels a little bit more like a chore.

Both communities are 🔥 though

I didn’t expect the savings to be that great! Glad it worked out!

`@bluwy/giget-core` is now back to a small 90kB install size thanks to @ayuhito.com's `modern-tar` package! Perf is also slightly faster.

We reduced Cloudflare Workers cold starts by 10x by optimistically routing to servers with already-loaded Workers. Learn how we did it here. https://cfl.re/3Kf8PGa #BirthdayWeek

I’ll look into it!

I don’t expect it to be faster at all as some alternatives use specialised dependencies to replace Node streams entirely. But I also don’t believe the difference is significant.

I just released a new zero dependency streaming tar parser and writer that is built with the browser-native Web Streams API!

Please check it out! It's awesome 📼

New blog post, reflecting on nearly seven years since the Firecracker launch, and how we're using Firecracker to power serverless databases (in Aurora DSQL) and infrastructure for AI agents (in Bedrock AgentCore).

Rolldown v1.0.0-beta.39 has been released!

⚡ macOS Performance Boost: 10%-30% faster bundling, up to 45% in extreme cases.

🎯 Cross-Chunk Optimization: Support for __NO_SIDE_EFFECTS__ annotation, as well as
better tree-shaking across module boundaries and more efficient DCE

one of the most common issues is inconsistencies in builds due to the weaknesses of scraping

Google Fonts is incredibly dynamic serving completely different files depending on your useragent, so often there are tradeoffs that lead to worse situations for one type of user over another

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!

some npm folks might be looking into scope based solutions

The WebAssembly 3.0 spec is complete!

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)
