399 for a sensor and rpi. I'm out.

A format requiring a program to decode is nuts. Might as well bundle 7zip with every zip file.

this man autisms

Yeah, I don't think the authors _actually_ mean that. I think English isn't their first language.

We should try to be charitable (but with a healthy amount of skepticism!); it's possible they meant "Even a child [with a good understanding of Litex] could [mechanically] formalize this multivariate equation in Litex in 2 minutes [as opposed to remembering and writing Lean 4 syntax]"

And that's all in my rare spare time.

Forth really shines in microcontroller or esoteric computation machines, but further more, people don't realize their C compilers are billions of dollars of development, and they'd never be able to do it in the first place. A Forth on the other hand can be developed in a month (I'm being honest-to-god realistic here. A lot of people would say "a weekend", but let's be real, anything useful will be more than a weekend. I'm trying to convince you this isn't bullshit :)).

If you have any more questions let me know. I was bit by Forth about 2 years ago but had read about it long ago when I was like 16 and passed it off as too hard. It's the same shit as when FP took off: it's a different mental model, so it will take time to morph your mind.

Edit: read the larger comment below, and they are totally correct:

> most Forth tutorials today are written by people who don't really know Forth

One day I might write a small Forth novella teaching how to actually think about Forth programs. In these 2 years I've had to just practice and write programs to see common patterns or idioms - kind of exactly like when I was learning Haskell years ago.

There's this cool site that already done this for like 2 years https://text-to-cad.zoo.dev

God is an extraterrestial or not? :)

The beginning of an alternative-universe candle computer that could've been used in the past.

When you feel the 500+ eyes that read this and go "wow".

Uh, how much simplicity do you really gain? What's an instance of needing to backtrack?

How is Russ so f'ing cracked. The brain on this human. 99.9% of us will never touch his intelligence.

Wow these are really cool ideas.

who even reads stuff anymore

edit: looks like they fixed it

I'm not sure if you actually clicked through - while OpenSCAD is absolutely dope, Zoo Design Studio offers the same capabilities and more.

Just like OpenSCAD, ZDS offers a code CAD experience if you like. It's a hybrid between the two worlds of traditional CAD and code CAD.

Unlike OpenSCAD, you can have real typed code. You can specify real dimensions. That's not a thing in OpenSCAD.

Unlike OpenSCAD, ZDS generates STEP files with BREP geometry. OpenSCAD outputs meshes only.

I'm a huge OpenSCAD lover, but to dismiss this so fast is a bit disingenuous :)

This seems so obvious

Ok, wow.

MCP is REALLY taking off FAST D:

What a neat idea.

We could use emulators to stitch together code from binaries compiled for particular CPUs.

Not the same when the machines in question are not on the same level...

uses brep

replicad

The manual has a nice benchmark: "5200 additions per second" B)

Probably 0.0001 Far-crys. My best guess!

Ben Eater? What're they eating? :D

Chuck Moore's GA144 requires a fabrication factory to create. My4th doesn't! How's that for a comparison?

If it's any peace of mind, the parts to build them should be available pretty much forever. It's possible I do more runs in the future :) Just for the sake of growing the Forth hardware community!

Extremely inspired by Forth, when I discovered this custom CPU design specifically for Forth I couldnt hold myself and went on the expedition to purchase the parts to build one. Unfortunately it only made sense to build 5 and sell 4 to cover costs.

I have 3 remaining My4th Lights I'm looking to sell, and given how niche this space is, I figured I'd try here on the business-tech focused YCombinator. I've sold one to a very happy customer.

I finally got the time to write up a proper little sales page:

What a stupid piece. We are making leaps every 6 months still. Tell me this when there are no developments for 3 years.

> I wonder how many consumers fall into this sunk cost fallacy scenario that Apple has designed.

Millions. Let that sink in.

But can we make it smaller

Someone's living under a rock :) Far from the truth.

Same thing with income tax brackets. You need conditional logic.

+1 for ledger. It has been the best one I've used. The fact you can script it is f'ing amazing. My taxes have been on-point for 2+ years now since I started using it.

I would love for you to elaborate on lessons learned in the project readme!
