Question for the people who have used the CH32V003 or more generally WCH, either for hobby or production, what is the current state of documentation and toolchain for these chips? Positive experiences, war stories?

Are there similar solutions without 3d view? I want to get a simulator that can show me what is going in the circuit, ideally slowed down a lot. For example I was making a dongle with resistor and capacitor which was delivering a pulse-short (i.e. removing power for a short period of time instead of delivering an impulse) and while I was able to confirm overall idea with some online simulator, dialing in capacitance and resistance required physically switching components. Ideally I want to be able simulate such transient effects and arrive at specific numbers ready to be soldered.
And I want it to be free/open-sourse ideally :)
Sounds like you are looking for a SPICE like simulator, there are quite a few free/open:

RIP to every single camera in existence if that happens. Lidar is awful with damaging camera lenses.
Is there any deeper study on long term effects regarding retinal damage?
I would imagine, even with safe dosages, there would be some form of cumulative effect in terms of retinal phototoxicity.
More so if we consider the scenario that this becomes a standard COTS feature in cars and we are walking around a city centre with a fleet of hundreds of thousands of these laser sources.

I couldn't find any changes on their keyturn stuff with the 'Webhosting' products?
Is the price hike only on Hetzner's offer for dedicated or VPS servers?

The concept of a physical card is obsolete. That North Americans and western Europeans for a good part still use them is just stickiness of the infrastructure, and habits.
Developing countries have mostly leapfrogged to total contactless payments.
In South Aast Asia, you typically scan a QR code and approve a payment from your own phone. Far less fraud as a result. Nobody is able to touch your card, you don't have one.
Europe likely identified they better make the jump.

We have progressively absorbed single function items into a mobile computer.
Watch, notepad, calendar, phone, flashlight, camera, dictionary, encyclopedia, etc.
The issue with declaring single function items as obsolete is that it removes redundancy and really sets us all up for an increasingly more critical single point of failure in our pocket.

> Windows 11's file browser lags when opening directories with more than 100-ish files. Windows 11's file browser takes a few seconds to open at all.

I can almost guarantee this is from some endpoint management software your company installed.
I have a Windows 11 workstation that I use all the time for some CAD software and the occasional game. Everything is fast. There's no lag with context menus or browsing directories with a lot of files.
If I have to browse network CIFS shares with a lot of files, Windows does it better than my mac or Linux boxes by a mile. I've switched over just to Windows a time or two just to deal with high file count shares.
> If Windows 11 struggles this badly on a brand new laptop that I'm certain would retail for $4000+, I can only imagine how miserable it is for everyone else.
I put Windows 11 on an old low powered laptop for a family member. FYI you can easily circumvent some of the Windows 11 requirements and put it on old hardware.
It's fast. It doesn't have any of the problems you're describing.
I do wonder how many of the "Windows 11 is painfully slow" comments are coming from people with corporate laptops with extremely laggy endpoint management overhead.
> I can almost guarantee this is from some endpoint management software your company installed.
I had the same issue with a loan machine from a client, super responsive onsite, but once I connected through a VPN from an external network, all the basic functionality in the file manager was brought to a halt. Even something as simple as right click on a folder to show a context menu would take several seconds.
The files were all local (also with Onedrive sync disabled) so I am almost positive it was whatever they were using for endpoint protection (Can't recall 100% but probably something from CrowdStrike).
I had to put in more effort regarding RAM use and flash size, but I managed to fit a game into the 16kb limit regardless: https://github.com/kpcyrd/game-streetcat2026
