Strongly endorse this list of rules for when WebAssembly makes sense vs when JavaScript does www.openui.com/blog/rust-wa...

Nice when a correctness fix makes things faster: github.com/emscripten-c... Unsafe pointer casts usually trap in wasm, but as an option they can be "emulated" to work like in native builds. This PR fixes a bug *and* makes things 2x speedier 🚀

Safari Preview 238 adds WebAssembly support for JSPI: developer.apple.com/documentatio... JSPI lets wasm programs use async Web APIs in the sync ways they expect

Related to this, this is an interesting post by a former colleague: john.regehr.org/writing/clau... where he says that the KINDS of bugs that CCC introduces are just very weird.

If it wasn’t for the heroic efforts of thousands of trees like this, our nation’s rivers would be at a standstill

Some thoughts on AI and math, inspired by “First Proof”: www.daniellitt.com/blog/2026/2/...

What is the relationship between memorization and generalization in AI? Is there a fundamental tradeoff? In infinitefaculty.substack.com/p/memorizati... I’ve reviewed some of the evolving perspectives on memorization & generalization in machine learning, from classic perspectives through LLMs.

PR up to add an "idempotent" compiler attribute to binaryen for wasm optimization: github.com/WebAssembly/... Useful for e.g. class initialization in Java, which only happens once - later calls can be removed.

How is it possible to play jazz like this on guitar www.youtube.com/watch?v=AnQC...

im not a linux evangelist but people post on here weekly like "i miss when computers were more like the early 2000s and had basic software and i didn't have to pay attention to all the flashiness and complexity and updates" girl what you desire is running stable debian on a spare thinkpad

Binaryen, the WebAssembly optimizer, released version 126: github.com/WebAssembly/... Includes many new optimizations, as well as new intrinsics for compiler developers: github.com/WebAssembly/...

Binaryen, the wasm optimizer, now has a way to mark a function as being removable if it is unused: github.com/WebAssembly/... Several toolchains have asked for this, so that more code can be removed in optimized builds.

"Multiverse" the AI company wtf. that's like if we had "Mobile" the virtual reality company "Bitcoin" the quantum computing company "Cloud" the biotech company

still recovering from the tradcath wedding I attended the other night … where I tortured one of these guys until he admitted that he didn’t think french people could be saints

Just released a new version of wasmbin (github.com/RReverser/wa...) with complete Wasm 3.0 support contributed by github.com/cyruscook 🥳

Why Kotlin + Wasm, and why this combination is the future of web development 🕸️ Listen to the recent podcast episode with the Kotlin/Wasm team lead 👇

you have probably heard that webassembly supports garbage collection. are you looking for an ahead-of-time compiler for wasm with gc? as it happens, i have written a little monograph on the topic wingolog.org/archives/202...

If you care about compiler intrinsics for WebAssembly, this might interest you: github.com/WebAssembly/... Feedback welcome!

Guess what genre of book this line is from

Today in "software performance... 🤨😞", a few lines make wasm-opt 3x faster on Windows github.com/WebAssembly/...

From the greatest hack of all time (asm.js) to running in billions of browsers, edge networks, and embedded systems. The oral history of WebAssembly's first decade, from the engineers who built it. bytecodealliance.org/articles/ten... #WebAssembly #Wasm #BytecodeAlliance

Interesting defense against Spectre security vulnerabilities

Reebok website is open-minded

That’s a damn good bodega cat.

Wikipedia turns 25 today! 🎂📚 To celebrate, we’re looking back at its baby pictures—some of the earliest captures of the site, preserved in the #WaybackMachine. Take a nostalgic peek at early Wikipedia ⤵️ web.archive.org/web/20030301... #WikipediaDay #Wikipedia25 @wikipedia.org

WasmGC is coming to GraalWasm, unlocking the power of JVM garbage collectors for #WebAssembly! This will also get GraalWasm a lot closer to implementing the full Wasm 3.0 spec. Join @ssmith.bsky.social and me at @jfokus.se next month to learn more: www.jfokus.se/talks.html?s...

signedpage.com/collections/... There is a new place to get a signed Robin Hobb book, thanks to Shawn Speakman and the Signed Page. Purchase the book and request an autograph. I will go to the warehouse and from there, Shawn ships to you. Thank you Shawn,

Lots of people with takes about Dan Wang's recent post, but here's a niche response to the bit in the picture: No, do not stop halfway through Piranesi. Clarke's genius is shown exactly in how the second half grounds the first in reality, and builds a synthesis.

omg

The Bun JS runtime is very nice for reproducing Safari problems (JS and/or wasm) without a full WebKit browser: github.com/emscripten-c...

We have a NEW demo up on Steam that has an updated Procedural Survival world and also allows you to play one "Adventure" world, IsleOfVox! See which you like better and let us know :) www.youtube.com/watch?v=wicM...

Safari 26.2 is out, which fixes wasm exceptions: github.com/emscripten-c... Looks like it has some other wasm improvements too, like JS String Builtins (important for GC languages): developer.apple.com/documentatio... Nice work!

Nice to see a human defeat a top chess engine for once...

You may want to enable SIMD in wasm projects (if you are targeting new-enough browsers/VMs). Just adding -msimd128 to clang/emcc/etc. will do LLVM autovectorization, which turns out is quite good on wasm: github.com/emscripten-c... A few nice benchmark speedups there, some unexpected.

So if you're going to be doomscrolling today, at least make it a journey through decades of community creativity that helped shaped gaming as we know it. Maybe something you made is in here? doomscroll.cx

Binaryen, the WebAssembly optimizer toolchain project, is now listed on the wasm website's features page: webassembly.org/features/ As mentioned there, it has support for all standardized features (and many in-progress ones)

wild. not what anyone would have predicted as the endgame for a JS runtime

Holy shit, looks like in the right combination* WebNN inference on GPU is over 5x faster than WebGPU 🤯 Still looking for the catch, in all my previous experiments it was *slower* WebGPU, and still happens if any conditions below are not met. This is all hightly unstable but exciting!

In case you didn't notice, #WebGPU is most likely available in your browser now!

Seriously considering putting a bounty on x86-64 support for copy.sh/v86: github.com/copy/v86/iss... A proper modern JITting emulator on the Web platform (including non-jailbroken iOS) would be amazing! I'm amazed how fast the jitcode can be, even with softmmu.

This week on the blog: Hoplites! We're taking a crack at explaining the long-running debate over the nature and significance of the ancient Greek heavy infantryman, the hoplite, and the phalanx in which he (mostly) fought. acoup.blog/2025/11/14/c...

Unreal Tournament can now be played IN A BROWSER dos.zone/mp/?lobby=ut Along with other late 90s PC FPS classics but yeah. UT99 in a browser window... just fantastic. Thanks to the r/LGR subreddit for letting me know about it!

The ending to A House of Dynamite (2025) could have been a lot better (and without changing the movie's message) kripken.github.io/blog/movies/...

Emscripten 4.0.19 is out! 🎉 github.com/emscripten-c... A major improvement for dynamic linking landed: the main module is built statically, without relocation overhead, making it smaller and faster. Only dynamic libraries now have relocation overhead. This makes dynamic linking much more useful 🚀
