I hadn't heard of the requirement before. Mandatory registration originally seems to have been intended to address bike theft. All bicycles sold in California must have a serial number. A significant number of cities (most?) had ordinances requiring registration. But few people knew about it and even fewer registered their bikes.
They're also run far closer to the edge of their operational limits than CPUs, so you're far more likely to get one that barely passes manufacturing tests, then degrades just a little tiny bit and stops working.
Ebay has filters to display sold listings, so when you're looking to buy something, check out the closed auctions and see what they're going for. If the prices are similar, you might as well buy from fixed-price listings, but if auction prices are lower, you can save a lot by being patient.
You can also save searches for a fixed-priced listing below a specified value, and enable alerts, so that if someone lists something that's priced to sell, you can get it quickly.
It's more a matter of exposing hobbyists of one vertical to what exists in another. Low-power RISC microcontrollers and microprocessors were superseded in popularity by the ease of a Raspberry Pi SBCs running Linux, that could act as a host to its own development.
Now that Raspberry Pi has entered the market, hobbyists that were only familiar with SBCs are now being introduced to the flexibility of Low-power RISC microcontrollers and microprocessors.
There's also some new products on the market that are the best of both worlds, with the system-in-package form factors and easy bare-metal development of the RP2XXX line, that still have the ability to run full Linux, like the Bouffalo Labs BL808 and the Sophgo SG2000. Check out the Ox64 from Pine64 (https://pine64.com/product/128mb-ox64-sbc-available-on-decem...) or the Duo series from MilkV (https://milkv.io/duo) for breakout boards and development boards.
Are there any up-to-date WebKit browsers for Android? The best I could find was Lightning, but it hasn't been updated in years.
Edit: I found A Lightning fork called Fulguris. It didn't work with the JPEG XL test image, but I really like the features and customizability. It's now my default browser on Android.
The closest thing I know of is Igalia has a project trying to port https://wpewebkit.org/ to Android https://github.com/Igalia/wpe-android and they have a minibrowser example apk in the releases of the current state (but I wouldn't call it a Chrome drop in replacement or anything at the moment - just the closest thing I know on Android).
