And this comment is being downvoted as well to hide the fact.

Wow this was moved fast off the frontpage! Now on page 3 after 50min. Just FYI.

Relevant paper on lattice types (BloomL): https://dsf.berkeley.edu/papers/UCB-lattice-tr.pdf In addition to this, you’ll need a causal register (per-key merkle clock) to order concurrent edits, rather than drop one. La

Completely different. The ST and TT used bitplanes whereas the Jag is chunky, and can support both YUV and RGB colourspaces. 640x200 is possible at least https://youtu.be/XI3Pvx5Yh1U?si=2bp93CeNYPTGZZic

OOI why did you go with RC at the lattice bottom rather than generational refs? Not sure how in touch you are with the author of Vale? What would be good is if effects are used to discharge the ownership obligations, that should dovetail we

Yes that’s pretty much how I’ve used AI, though phase zero and one had to be hand-coded until there was enough code for the AI to iterate off. Hand debugging and then showing the AI helps to narrow the number of errors, and how to triage fo

Depends what you define as a cyberdeck. If you look low power/ non-linux there are many innovative decks: https://hackaday.com/2023/03/06/low-power-challenge-the-pota... https://www.youtube.co

You might be interested in the Baochip https://www.crowdsupply.com/baochip/dabao/updates/our-campai... Probably the most open chip on the market, and sits between a pi and a pico

Not quite the same thing, but you can build a similar thing to run linux relatively easily, and the keyboards can be really good that way. You can swap out the SBC for one of your choice eg. https://www.lattepanda.com/lattep

There’s a wealth of retro machines out there that cater to this. A sample: https://www.olimex.com/Products/Retro-Computers/Neo6502/open... https://www.olimex.com/Products/Retro-Computers&

There’s a definite overlap between this and the Cardputer Zero: https://youtu.be/lhS0trmBAAU?si=lLmCKdK3eHyMMAR0 M2 slot or a clipon addon? Nice to see more Swiss Army knives in this space

I think that’s the beauty of PG here, you can find solutions to most of this: Index creation https://stackoverflow.com/questions/23876479/will-postgresql... JSON->DB schema https://jsonschema2db.read

Good points, but Postgres has all those, along with much better local testing story, easier and more reliable CDC, better UDFs (in Python, Go etc.), a huge ecosystem of extensions for eg. GIS data, no licencing issues ever, API compatabilit

Thanks! One last question is whether it can boot from external EEPROM? This is mainly with reference to Ken Thompson’s Reflections on Trusting Trust paper ( https://www.cl.cam.ac.uk/teaching/2324/R209/Reflectio

Great work on the chip, I’m really onboard with the trusted computing aim! Is there a way to bootstrap binary code into the reram? I’m thinking being able to ‘hand-type’ in a few hundred byte kernel rather than use a flashing tool

If you don't mind, could you drop some code? I'd be interested to see the result :)

Apart from transputers mentioned already, there’s https://greenarrays.com/home/documents/g144apps.php Both the hardware and the forth software. APIs in a B2B style would likely be much more prevalent, less adverti

Very impressive demos! I did a quick look through the docs- it’s single threaded (in the cpu sense) and not multi process yes?

It was a massive shame the TV-toy project at Sinclair did not work out. It was a SOC/low cost computer based on the Inmos transputer (Called the T400, an M212 without dedicated link hardware) around 1983. That might have kept Inmos afl

Tip of the hat there, it’s a very selfless thing to commit to caregiving. From a 50kft view, we have an aging demographic globally, and the bet seems to be robotics- hopefully they will get good enough to help meaningfully in this capacity.

I get the impression that the Atari AMY chip was an inspiration? Wonderful to see how the Alles speakers are implemented!

I agree you would need to specify the markdown to allow more implementations. https://github.com/jgm/djot Would make a good DSL inside languages, combine that with compile-time execution so that blocks can auto-recalc

I think this is the crux of the issue, use like this is like a real program, just built up incrementally in a notebook rather than a repl or shell-with-pipes, and with manual error handling. The STEPS project was all about this- a way of in

Although it’s a bit weird, Able Forth has the explicit word ~ https://github.com/ablevm/able-forth/blob/current/forth.scr I do prefer this as it keeps the language more regular (fewer surprises)
