are there any benchmarks on sector lisp
I'm assuming you are referring to https://github.com/jart/sectorlisp which I gather is an attempt to make a Lisp that fits in a disk boot sector?

I think SIMD was a distraction to our conversation, most code doesn't use it and in the future the length agnostic, flexible vectors; https://github.com/WebAssembly/flexible-vectors/blob/master/... are a better solution. They are a lot like RVV; https://github.com/riscv/riscv-v-spec, research around vector processing is why RISC-V exists in the first place!
I was trying to find the smallest Rust Wasm interpreters I could find, I should have read the source first, I only really use wasmtime, but this one looks very interesting, zero deps, zero unsafe.

I get what you are saying as to be so small that there isn't a place of bugs to hide.
> “There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult.” CAR Hoare
Even a 100 line program can't be guaranteed to be free of bugs. These programs need embedded tests to ensure that the layer below them is functioning as intended. They cannot and should not run open loop. Speaking of 300+ reimplementations, I am sure that RISC-V has already exceeded that. The smallest readable implementation is like 200 lines of code; https://github.com/BrunoLevy/learn-fpga/blob/master/FemtoRV/...
I don't think Wasm suffers from the base extension issue you bring up. It will get larger, but 1.0 has the right algebraic properties to be useful forever. Wasm does require an environment, for archival purposes that environment should be written in Wasm, with api for instantiating more envs passed into the first env. There are two solutions to the Wasm generating and calling Wasm problem. First would be a trampoline, where one returns Wasm from the first Wasm program which is then re-instantiated by the outer env. The other would be to pass in the api to create new Wasm envs over existing memory buffers.
See, https://copy.sh/v86/
MS-DOS, NES or C64 are useful for archival purposes because they are dead, frozen in time along with a large corpus of software. But there is a ton of complexity in implementing those systems with enough fidelity to run software.
Lua, Typed Assembly; https://en.wikipedia.org/wiki/Typed_assembly_language and Sector Lisp; https://github.com/jart/sectorlisp seem to have the right minimalism and compactness for archival purposes. Maybe it is sectorlisp+rv32+wasm.
If there are directions you would like Wasm to go, I really recommend attending the Wasm CG meetings.
https://github.com/WebAssembly/meetings
When it comes to an archival system, I'd like it to be able to run anything from an era, not just specially crafted binaries. I think Wasm meets that goal.

*Laughs in autocmd*
Based on this, the next thing you wrote, and your reference to running a minimal Gentoo: I think you might be a Scheme fan in the making. Scheme is the minimal Lisp. (Okay, that might be sectorlisp which fits in 512 bytes.) It’s hands down my favorite language. While it’s evolved on its own to be more of a superset of Scheme, Racket is my Scheme of choice.

That's pretty much it!

Show HN: Lisp with GC in 436 Bytes
SectorLISP has always had a C implementation for explainability. It started off as ugly C because it was actually used to generate the assembly code for the first ~900 byte version. See https://github.com/jart/sectorlisp/blob/a561e031aec03270459f... and https://github.com/jart/sectorlisp/blob/a561e031aec03270459f... Once we reached 512 bytes I started deleting a lot of the C code since things like assembly macros weren't needed anymore, since the assembly was now being written by hand. https://github.com/jart/sectorlisp/blob/main/lisp.c
Once I cleaned up the C code, I noticed that the entire program didn't use pointers at all! (Except of course to interop with Bestline, but that could be replaced with fgetwc() instead). That's when the idea occurred to me that, since it didn't use pointers, it was also technically valid JavaScript too. So I asked around on Twitter to see if anyone's done a C / JS polyglot before. I got some helpful tips from a code golfer in Estonia who experimented with the idea and he told me about the paragraph separator trick. https://twitter.com/angealbertini/status/1463755612345540611

A completely-from-scratch hobby operating system
Just curious how hard it would be to forego POSIX entirely if you were building an OS. I know TempleOS is entirely from scratch. I'd like to implement a small LISP like SectorLISP [1] (see yesterday's posts too on HN). I don't know much about building my own OS, so I'd like to start with something like MenuetOS (my first PL was asm), SerenityOS, TempleOS, or this one. I'd like it to be completely an 'island', i.e. POSIX not a requirement. I want to use it to hack on in isolation without any easy copy/paste shortcuts. I know Mezzano exists, and it has booted on bare metal, but I would like to start with the OS's above, implement my own LISP, and go from there.
Any other OS recommendations base on my ignorant, but wishful, reqs above? I realize there are some others in Rust too. Thanks!

Redis License Changed
I'm curious about something: I suppose Salvatore still owns the copyright for most of the code? The old license does include his copyright, up to 2020: https://github.com/redis/redis/blob/7.2/COPYING So I think this change couldn't have been done without his explicit consent? Or did he transferred his rights to RedisLabs or a foundation?
Redis.io no longer mentions open source.
They have still not changed meta description on their page. It still says it is open source ^^

Redis Adopts Dual Source-Available Licensing
First they break lolwut (https://github.com/redis/redis/issues/12074) and now this.
Redis Inc. is moving the https://github.com/redis/redis/ project away from the three part BSD license to a dual license using two non-OSI approved license. This comes after previous comment from them saying that "... the Redis core license, which is and will always be licensed under the 3-Clause- BSD".
> They get paid for it. Don't try to spin this as if it's someone people working on it in their spare time out of the goodness of their heart. It's just their job.
No, you can't have this both ways. I'm the main contributor from AWS, and I've worked many times on weekends because I care about open source. I like helping people, I don't need to be paid to do it. Many of the AWS folks that made changes were normal engineers that were excited to be part of Redis. https://github.com/redis/redis/pull/10419 and https://github.com/redis/redis/pull/8621 are both examples of features someone from AWS built in their free time. We're all upset about this. Not because Redis deserves to get paid, it's that they acted like they were being good stewards of the open-source community and then they changed their mind.
