Yeah, the content + feel felt like I'm reading this in 2013.

Nothing wrong with that, it's a good thing that stuff is discovered anew [as opposed to being lost/forgotten], but it did bring a smile to me.

Yes, that's the right idea.

It's less about browsers, and more about server/edge/local-agent runtimes.

Wasm lets you have

- sandboxing (untrusted actor code)

- clean snapshot/restore

- portability of actor across machines

If you don’t need those properties, then yes ... native is obviously the better choice

Yes, simply for local inference -- not much, native is the obvious choice.

The value would be in actor processes, where you can delegate inference without paying the 'copy tax' for crossing the sandbox boundary.

So, less "inference engine" and more "Tmux for AI agents"

Think pausing, moving, resuming, swapping model backend.

I scoped the post to memory architecture, since it was the least obvious part ... will follow up with one about the actor model aspect.

Agree, maybe "changes the physics" was too strong, shared cpu/gpu memory is not new.

What is different then is the combination of

1. UMA memory (and yes, iGPU had this, pre-M1) 2. enough bandwidth / GPU throughput for local inference 3. straightforward `makeBuffer(bytesNoCopy:)` path

So, the novelty isn't the shared memory itself, but the whole chain lining up to make the Wasm linear memory -> Metal-buffer approach practical + performant enough.

(and not saying there's some Apple Silicon magic here either ... it'd work anywhere there was UMA and no-copy host-pointer path)

This is crazy impressive ... the kind of thing that should inspire one to do more, much more, than whatever "mere plumbing" one happens to be doing at the moment

Show HN: Try Gerbil Scheme in the Browser

agambrahma — Mon, 16 Mar 2026 02:10:27 +0000

Gerbil is a Scheme built on Gambit that compiles to native code via C. It has an actor-oriented concurrency model, a rich module system, and a batteries- included stdlib. I built a browser playground to make it easy to try without installing anything.

Briefly: - A real REPL with state that persists between expressions - 10 guided examples from basic Scheme through pattern matching, hash tables, higher-order functions, and actors (but, do go to https://cons.io for the full docs) - A scratchpad for multi-line code that evaluates into the live REPL session - Snippet sharing via short URLs

To keep this short, some implementation details here: https://abacusnoir.com/2026/03/15/a-playground-for-gerbil-sc...

(Does have limitations in this early version, see the post for details on those too)

Show HN: Patchwork – async collaborative image quilts

agambrahma — Mon, 09 Mar 2026 16:12:34 +0000

When my kids were young we'd flip restaurant menus over and fill a hand-drawn grid with crayon doodles, one square at a time. I wanted to turn that ritual into an app.

Patchwork lets you create an NxN grid, share an invite link, and have collaborators claim and fill squares with images asynchronously.

Squares are visible as they're filled: the quilt builds up slowly over hours or days, and checking back to see what someone added is the whole point.

New comment by agambrahma in "UAPs as Coherent Field Entities"

agambrahma — Sat, 29 Nov 2025 06:11:44 +0000

Applied plasma physics (spheromaks, solitons, field topology) to UAP observations. Explains the "five observables" better than the spacecraft model ... though radar signatures and energy density remain problematic (!)

Speculative but grounded in real physics (I used ChatGPT/Gemini as thinking partners, then verified claims)

[I'm likely missing something, but]

"EVM-compatible, built on Reth" => they're essentially building a private Ethereum fork with a fancy validator selection process.

Couldn't they just get these benefits (predictable fees, fast settlement) by ... running a database between these financial institutions?

If Stripe controls the validator set (even indirectly), then ... just a distributed database with extra steps, no?

Show HN: macOS Gemini/Cerebras text quick-chat app

agambrahma — Tue, 02 Sep 2025 05:48:27 +0000

I've built a native macOS AI chat application that supports both Gemini and Cerebras providers through a single interface. You can choose between either depending on what each conversation needs, then select a model from either. Text only. Everything stays local to your mac.
