This is a lot like One Laptop Per Child, but more vague. What is it supposed to do? Why have one?

It's not that the system doesn't come with a browser. It's that the browser is apparently built into the operating system. Remember IE 6?

If you're going to rethink computing devices, the next thing is probably a big screen, a camera, and a good microphone array. No keyboard. You just talk to it and occasionally gesture, and it organizes and helps you.

Like clockwork every year or so someone emerges and says "I'm going to fix computing" and then it never happens. We're as mired in the status quo in computing as we are in politics, and I don't see any way out of it, really. Also the website is very low contrast (brighten up that background gray a bit!)

Gotta keep trying then!

The landing page reads like it was written with an LLM. Somehow this makes me immediately not care about the project; I expect it to be incomplete vibe-coded filler somehow. Odd what a strong reaction it invokes already. Like: if the author couldn’t be bothered to write this, why waste time reading it? Not sure I support that, but that’s the feeling.

What's odd is how certain people seem to be about their intuition about what is and isn't written by an LLM.

I don't understand why they're particular about writing their own esoteric language. If they want people to buy and engage with it, software has to be the gateway, and that's easier to write in a language people know.

Next you'll tell me urbit, nock, and hoon never caught on

I have been having a lot of fun with PicoCalc. It's not targeted at end users but is fun for developers alike who want a taste of developing things from first principles. More than anything it can live independently from your other devices.

I keep seeing the videos pop up. It does look really cool. I see it has a basic interpreter, so I guess kinda like a C64?

It comes with a basic interpreter, but the thriving community develops plenty of stuff: python, lua, forth, lisp... have nice ports which you can play with on device. There also is a library of software developed for rp2040 which have been ported, such as a mac classic emulator. If you feel that a micro controller is too low power, you can plug in a luckfox lyra which runs a proper linux with 128M of RAM.

Very interesting and ambitious project and nice design. I hope the author will be able to comment here. I'm interested to hear about the plans or capabilities in R' or Radiance for things like concurrent programming, asynchronous/scheduling, futures, and invisible or implied networking. AI is here and will be a big part of future personal computing. I wonder what type of open source accelerator for neural networks is…

Thanks for your comment! In terms of concurrent programming in Radiance, it's likely I go for something inspired by Go's simplicity and Haskell's power with STM[0]. Actors are also on the table, but likely as a library on top of the native system, whatever it is. The important thing is that everything that involves "waiting" be composable in this system: timers, network i/o, IPC, file i/o, etc.

For the AI/OS intersection, it is indeed a very interesting design space. The key insight really is that the better the AI knows you, the more helpful it can be to you, so the more you give it access to, the better. However, to be safe, the OS itself needs to be locked down in such a way that personal data cannot leave your device. This is why capabilities-based security is an interesting direction: software should not have access to more than what it needs to operate, and you need fine grained control over that.

If you have more ideas, please write us!

I love these guys for trying to do this. I just hope they’ve already made their money and can afford to continue doing this. It’s every engineer’s dream - to reinvent the entire stack, and fix society while they’re at it (a world without social media, sign me up!). Love the retro future vibes, complete with Robert Tinney-like artwork! (He did the famous Byte Magazine covers in the late 70s and early 80s). https://tin…

Thanks for the encouragement!

That is really cool! Making me want one even more. I might have fun picking that forth implementation apart.

Clean slate designs with arbitrarily radical designs are easy when you don’t have to actually build them. There are reasons that current architecture are mostly similar to each other, having evolved over decades of learning and research. > Perhaps model where processing and memory are one, A:very simple core per 1k of SRAM per 64k of DRAM per megabytes of flash, To serve what goal? Such a design certainly wouldn’t be…

> Software isn’t the only place where big-O scaling is relevant. > Fully connected graph topologies are great on paper, but the number of connections scales quadratically. For a 64-core fully connected CPU topology you would need 2,016 separate data buses. Nitpick: I don't think the comment you're replying to is proposing a fully-connected graph. It's proposing a hypercube topology, in which the number of connections…

This is what I meant. I also like the idea of optical, line-of-sight connections. If you do the hypercube topology everything a node connects to has a different parity, so you lay them out on two panels facing each other.

The thing that always worries me about these clean-slate designs is the fear that they'll ignore accessibility for disabled people, e.g. blind people, and then either the system will remain inaccessible, or accessibility will have to be retrofitted later.

It's funny you mention that because the first thing I thought when viewing this page was "is this a loading state? why is everything grey?".

I like the design. Minimal and loaded fast. I haven't dug into the pages' code but I'm guessing there's little or no bloated JavaScript.
