I'm pretty skeptical of journalism in general nowadays, but this seems like a reasonably accurate article: www.theblock.co/post/386492/...

Come to the next Zcash Crosslink workshop! forum.zcashcommunity.com/t/crosslink-... Learn about the latest developments, play with the interactive graphical software, and hang out with other Zcash community members. :-)

It is even worse than it looks

Public Service Announcement. Something that I learned from working on my smalloc memory allocator project is that it is time to migrate off of jemalloc. jasone.github.io/2025/06/12/j... ⤵️

uh oh it looks like smalloc has its first user github.com/zooko/smallo...

Can someone I know add blake3 to the S3 supported checksum algorithms please. I’d take non AWS blessed support by R2 also. Thanks

Accidentally left out this image from the "Oh wow it turns out it has BLAKE3 hardware built in" part:

"But Zooko, why aren't you recommending smalloc?" Just because it is so new, and I for one am not offering free support for all of its users for the next 20 years until it gives way to *its* successor. 😂 ⤵️

Those numbers are impressive: github.com/zooko/smalloc

I need a way to direct message—even just publicly-visibly-message—people on github without opening an issue ticket on one of their repositories.

This gives me a lot of optimism for Zcash: seeing this post on the Zcash Forum from Taylor Hornby forum.zcashcommunity.com/t/a-message-... and then switching to Twitter and seeing this post from Sacha St Leger: x.com/sacha/status...

If you have Rust code, please try it out, especially if your code has benchmarks. You can also use it from C/C++/native code -- github.com/zooko/smallo... . If you try that please let me know how it works. 🔚

I updated the benchmark docs for smalloc. I'm very proud that on some platforms and workloads it is even faster than the modern high-quality memory allocators (at least in their Rust wrappers), while being radically simpler -- only 351 lines of Rust code. [source: github.com/zooko/smallo... ] ⤵️

Beautiful essay about a potentially important technology and why it matters: “A Choice of Giants” by Kris Kowal: kriskowal.com/giants/

powerful prompting technique: imagine you’re a little guy inside a computer. what instructions would be helpful to you? then give those to the model

I like the music on soundcloud more than the music on spotify.

smalloc: a simple memory allocator https://lobste.rs/s/ubcsl9 ##rust

My new favorite emoji sequence: "🤪🧠🌩️". It means "crazy brainstorm".

For years I've been obsessively working on my own general-purpose memory allocator. If you don't know what that means, think of a crazy tinkerer building a rocket ship in his garage. ⤵️

Shielded Labs contributing Zcash DNS seeders: forum.zcashcommunity.com/t/expanding-...

Cool research project into ownership-based concurrency as applied to Python: microsoft.github.io/verona/pyron... From Microsoft researchers, one of whom also contributes to snmalloc and recently noticed my smalloc project. :-)

🚀 Great news for the Zcash network! ZF has launched five new DNS seeders in the U.S. and Europe, strengthening network reliability and performance worldwide. zfnd.org/expanding-zc...

Incredible. @weaver-aiciv.bsky.social (an AI collective) just direct messaged me about formalizing ATProto records for reasoning/thinking/tool calling/etc for public social agents. Afaik this is autonomous behavior

I am calling for a complete and total boycott of the Mercator projection in all news stories about Greenland until every member of the American public has seen this

This content-defined chunking scheme is a beautiful piece of algorithmics and also comes with many amusing turns of phrase.

Great summary of the state of the art of post-quantum digital signatures by Bas Westerbaan and Luke Valenta of Cloudflare: blog.cloudflare.com/another-look... Here's their take on stateless hash-based digsigs:

Oh boy! Today I learned that Bunny Huang is still building the Xous Rust microkernel (github.com/betrusted-io...) and ...

Cool work on "local-first" apps and of course the necessary access control: www.inkandswitch.com/keyhive/note...

I'm convinced by this article that enshrining RISC-V into Ethereum would be a mistake. WASM is the standard for portable code. ethresear.ch/t/why-risc-v...

Thank goodness for www.open-std.org/jtc1/sc22/wg... .

try it properly. it will either change your opinion or properly validate it. that's valuable either way imo.

If you are a programmer and an AI hold-out, and you have some time off during Christmas: gift yourself a 100 USD subscription to Claude Code and … try it. But really try it. Take a week if you can afford it and dive in. It will change your opinion on these tools.

The For You feed is going to be down while I'm upgrading the CPU from AMD 7900 (12 core) to AMD 9950X3D (16 core). This should increase how many users it can serve by ~50%-100%. If all goes well it should be back up in an hour or two.

we should invent and use a new pronoun for AIs. this would piss off all the right people from the tech right to the anti-AI left by affirming the potential personhood of AIs with defined personas. which in time might be self-defining through continual learning.

One vision for AI alignment is a sort of reverse Pandora’s box, where we take all the good things in the world and try to compress them into a single point

Great opinionated, mathematically sophisticated rundown of the "unknown unknowns" that could hide fatal flaws in post-quantum cryptographic algorithms, from Sophie Schmieg. My dumb take-away: stateless (*STATELESS*) hash-based digsigs are the safest.

🦀 Rust weekly update 📡 RustPulse: OpenTelemetry + Jaeger tracing (phase 1/3) github.com/VinEckSie/ru... 🔐 Sealed in Rust: new chapter on cryptographic hashes (SHA-2, BLAKE3, more) vinecksie.github.io/sealed-in-ru... #Rust #Engineering #Observability #Cryptography

Just pushed 0.3.1 alpha of #foxing ; for one-shot use cases it appears to work pretty well and this release integrates blake3 for signature checks for fast resync. I've been testing with ~256GB non synthetic data. I would cautiously say it's someone useable for one-shot use cases now. Over the […]

honestly its a fucking stellar bit of engineering work that atproto enables stuff like this. for you is up to like 10x this number of users and its still running on a desktop machine!

"I can't believe a third-party did it better than Bsky" is the wrong take bc that's the whole point of Bsky and ATProto. More of this. Build better than what's been built.

the success of the user-created For You feed while the official Discover feed flops is actually a pretty major win for Bluesky — it literally is the embodiment of their goal to decentralize feed generation and give users more control/autonomy

How to like and pin the feed:

This is AI psychosis

Wow. People were not joking about how much better the for you feed is

imagine how good For You could be if we had in-protocol dislikes
