You asked if there was "tangible benefit to end user or developer using ai assisted development". My answer is no, it can be done but has no benefits for this use case. Use Rust here, because its compiler acts as an AI safety net.

Use Rust if you're not writing code yourself. The borrow checker will catch all kinds of bugs that AI-generated code will happily compile in Zig but will blow up as UB at runtime. Zig's value prop is different and closer to a mode

It definitely is vibe-coded, but yogthos is a competent programmer who has been working on public Clojure projects and repos since 2009, and has maintained a large Clojure framework since well before LLMs were a thing. I don't think &q

Not slop, though. The main developer is Dmitri Sotnikov (yogthos), who's been around in the Clojure scene for a long time and knows what he's doing. However, you're right to point out that the development is moving really fas

Four day old repo with 92K lines added per day, okay... There is basically no evidence of human competence in this repo. This is yet another "rewrite in Rust with Claude" project that brings nothing to the table, but devalues expe

This was common back then. The PDP-8 had eight primary instructions, although one of them was multi-purpose. This helped keep the hardware simple when we didn't have ICs. RISC isn't about having a small ISA but about a regular, or

I was initially surprised because this is not a good use case for Scheme. The current C implementation is clean and efficient, and I'd rather use Scheme to replace some messy Python code with its dependency hell. And then I saw this: &

Not very far off, the IBM 1130 was very much built around its punch-card reader. I've written a backprop in Fortran IV for the 1130 and while it works, it was tedious. Add ten more years, and the IBM 801 could have been a CPU architect

What kind of virtualization do you use internally? I assume some kind of LXD fork? OrbStack really feels like a single-node Incus host.

The first AI winter was largely triggered by Minsky in a book he published in 1969, which mathematically proved that single-layer perceptrons couldn't solve non-linear problems. Favorite quote: "Our intuitive judgment is that the

Scheme has a coherent and minimalist design, but its ecosystem and abstraction facilities feel too sparse for large applications. When I started building a Lisp-based machine learning framework, Guile seemed like the right choice because it

I was thinking of curated replay buffers, which would act like "dreams". To prevent collapse, the offline dataset would mix the new mid-term data with a baseline of anchor data (the original training distribution) so the model doe

That's an idea I had a few months ago: after going through a compaction once the KV cache is nearing capacity, accumulate this knowledge into a dataset to fine-tune a LoRA during offline hours. This would create a three-layer memory sy

Strictly speaking, this is very domain-specific and doesn't enable any performance that Triton couldn't already achieve (eliminating global memory round-trips via epilogue fusion is nothing new). The real takeaway is the design s

Emacs Lisp is a descendant of PDP-10 MAClisp, which makes it one of the oldest Lisp dialects still actively maintained. Whether it's version 24.5 or 30.2 doesn't make much of a difference semantically.

Ink is the Electron of text-based apps. I tried OpenCode out of curiosity, it routinely used hundreds of megabytes of memory. I'll stick with Emacs as my TUI platform of choice, especially for tool-assisted development.

I wonder how they plan to implement that on decentralized social networks such as Nostr. I assume targeting big centralized networks such as X and Facebook is good enough.

Yes. The author mentions Claude for testing, but it was obviously used for the README and code as well. This is a giveaway for AI generation, from the docstring to the terrible opcode dispatch (Claude sucks at assembly or low-level optimiza
