Cool! It looks like you turned yourself into an NFT collection :)

I am arguably nonfungible

THAT WAS TOTALLY WICKED!!

It uses LVGL https://github.com/lvgl/lvgl

Oh that explains why it's fast!

LVGL... fast? It's used on meshtastic devices, and I've always felt it was rather clunky. /shrug

Is it possible to make a fast UI on say, an ESP32?

Wish I knew... I'm half way towards looking for companies who make white label android devices for a project of mine... I originally wanted to go stm32, but as soon as you add a touchscreen and want a responsive gui, my only options seemed like "smart displays" with pre-rendered ui graphics, or a full blown arm device. /shrug

Now I am curious what you're working on :-)

Well it runs at 20 Mhz, like a Motorola 68020 (Apollo DomainOS), so I would say, yes.

Microsoft has difficulties drawing (rounded) rectangles at 2 - 4 GHz but that's another issue.

But Motorola 68k in say... the Amiga (I don't know Apollo) would have additional chips for sprites and blitting, right? And the ESP - despite being extremely fast, doesn't have that extra support. So you need CPU... + tricks, DMA, triple buffering etc

Where are you getting 20MHz from? The OG ESP32 is a dual-core 240MHz micro...

I've been looking into this recently. It seems to be possible with the right kind of controller: https://www.youtube.com/watch?v=ZWtTmmne6Bo

Also the newer esp32-p4s have MIPI DSI onboard which apparently can do smooth HD.

Yes, see MS-DOS games. Now skills to do it 30 years later is another matter.

Is it possible though? I have never seen an LVGL demo (just plain C) able to present a demo or animation that is as "smooth" as a MS-DOS game on say a 486. Not that the 486 was butter smooth but it's not quite there. Maybe its the interface for the screen?

Is it possible to run it on Meta Quest 3? Or maybe someone could recommend the similar project for a VR headset? Thanks!

Same in Russia

What’s wrong with it if they studied the codeGPT solution well enough to explain it, answer the questions about corner cases and suggest improvements? Won’t it be a good indicator of the candidates skills? ChatGPT is one of the daily tools nowadays, we should not ban it, but the one using it should be able to understand and explain the code, and his logic, and explain how he architected the solution and how the LlM assisted him, and where it worked well and where not so good.

Probably becasue you are looking for people who can actually perform a certain job and not just come back with the ChatGPT answer.

If they can produce working code that solves the problem, and explain how it works, that is more than “just com[ing] back with the ChatGPT answer.” I'm not saying ChatGPT doesn't have its own issues, but this is not one of them.

I've had candidates who successfully did this to explain how a SQL JOIN works. But I'm not looking for candidates who can read a GPT prompt; I'm looking for people who deeply understand how a join works.

I really loved that you started with a multivibrator scheme instead of arduino

I’m really amazed by the fact how expressive and solid such low-res icons can be. Creating them is a true art

Indeed - we now routinely do so much less with so much more!

Can I quote you when I finally release my app in a week or two?

99% invisible is one of my most favourite podcasts, I recommend it every time when I talk about podcasts to someone

It's the first podcast I ever heard of, when my friend first explained that word to me. Glad to see it's still around.
