I feel like foregoing the whole PCB would be better, and just wirewrap, or "free-air" solder.

How would you handle LQFP or BGA packages?


What do you think the minimum pad clearance is for the clay?

You can dead bug an LQFP if you absolutely have to…


How does this idiotic ash tray of clay and paint handle bga?

Point to point is easily as functional or better than this.


What a rude and shallow thing to say about a creative project.

It’s interesting how angry this makes some people.

How well did Albert Hanson’s flat foil board handle BGAs?

Instead of looking for flaws, try looking for the insight. I’m reminded of this blog post that was on hn recently https://scottlawsonbc.com/post/shooting-down-ideas


Not looking for flaws. Looking for solutions!

I didn't invoke bgas, that was someone else.

I can easily explain how this art process could handle BGAs. As mentioned in the article, you could swap the indentation+hand-painted circuit traces with screen-printed traces on a flat surface.

Defending one idea isn’t shooting down another. Point to point wiring has its uses, for sure. But calling it an “idiotic ash tray of clay and paint” is shooting something down. But again, i think you’re conflating me with an earlier commenter.


You can express any number type in pure lambda calculus.

I can also implement compliant IEEE 754 floating point arithmetic, with all rounding modes and exceptions, in Conway’s Game of Life, and I can implement that on a Turing machine and emulate that Turing machine in Brainfuck. This does not mean it’s sensible — it would be a serious engineering project that should be decomposed, built in pieces, and tested or verified in pieces. Which even a Chinese LLM ought to be able to do in an appropriate environment with appropriate resources and an appropriate prompt.

But that is not what this is testing. And I’m not even sure which number system the mentioned roots of unity are in. Maybe it’s supposed to be generic over number systems in a delightfully untyped lambda calculus sort of way?

edit: after pasting the entire problem including the solution, ChatGPT is able to explain “GN numbers”. I suspect its explanation is sort of correct. But I get no web search results for GN numbers and I can’t really tell whether ChatGPT is giving a semi-hallucinated description or figuring it out from the problem and its solution or what.


Lambda calculus people have the phrase "adequate numeral system" because they've discovered many different numeral systems.

We pretty much already had the layoffs, at least that's my perception.

The next level of layoffs is probably still 25 years out.


There's layoffs, certainly.

But all the economic indicators suggest those are "bad economy" layoffs dressed up as "AI" layoffs to keep the shareholders happy.


The real “AI layoffs” are all the people that are PIPed because their colleagues are better at leveraging AI.

We must have a very different view of the world because in my neck of the woods companies are desperate for senior talent. And it's become even harder to find seniors now that everyone has access to a machine that can create the appearance of experience.

> The next level of layoffs is probably still 25 years out.

Hasn't even been 25 years years since the previous layoffs before the current ones.


How's this different from RepliCAD?

Replicad is designed primarily to be used as a library with the web editor as a helper. FluidCAD is designed to be used as full CAD package code + UI. I've outlined some of my motives in recent post: https://news.ycombinator.com/item?id=47721997

Now that Steve is part of a GitHub competitor to push jj, I see all these posts as just sales pitches.

I am quite happy for anyone to use whatever tools they find to be good. I'm also happy for anyone to use jj with whatever server they want to.

It is right to be skeptical of me, but I hope to keep that integrity by continuing to talk about things that I believe are legitimately good, regardless of anything else.


Thanks for the reply Steve - I think it's only natural, and charitably unintentional :) But almost everything I've seen upvoted around the Internet from you has been about jj and being directly tied to east river source control... I think that's a reasonable framing. I can only hope me signalling this maybe changes something. While I'm not a fan of jj (I'd much rather Pijul were to eat the world), I think you as a person is really nice and always have been "for the community", but I can't shake this current framing!

I mean, most people seem to think I solely post about AI these days, so it’s kinda funny to run into someone that feels otherwise!

I’m not sure why I’d stop posting about a project I’ve been passionate about for years, just because my job is adjacent to it.


You can't say it's adjacent to it, when your job directly involves the technology. You'd stop posting because anything you say about jj could be interpreted as a sales pitch for jj, and a lot of people can be turned off by that. That's one reason. Our lack of creativity is not proof of no more.

But I don't think "stop writing" is the only strategy to jump on...

Or maybe I'm just extremely unlucky to have only caught these kinds of posts and gained this framing! Totally possible.


This tutorial predates his involvement with ERSC.

I'd much rather read "Dropping everything for self-sufficiency"


or the top 1% of value holders means your connection to other holders is vastly smaller than the other 99%. also highly likely to get cancer no matter who you are. i think the odds are better than people think, was just a matter of time

regardless of that observation: i am glad it's good people working with good people on these problems!


So this is a smudge of like 4 projects? Huh. Definitely interested, but I wonder about the longevity of the system. That's one thing about the code cad systems I like: it's pretty easy to port code from one to another.


If you use Google in any capacity, you already have.


and this is why i, personally, use searxng these days instead of google or duckduckgo
