The device tree is a way of standardizing how the hardware description is maintained in the kernel. It's still information that is external to the board. You still can't load a generic kernel on any ARM board with a compatible instruction set architecture unless you have that additional information. What I'm talking about is that the board needs to be self-describing. Suppose a distribution has drivers for all the hardware on a new ARM board. It should not be necessary for the manufacturer to get the corresponding device tree into the mainline kernel, and neither should you need to look somewhere else for a matching device tree if it's not delivered with the kernel. The kernel should boot on the new board and the board should provide all the information it needs to load drivers for all peripherals. This could be as simple as mandatory standardized I2C access to a ROM with a flattened device tree blob. Whatever they come up with, ARM needs a STANDARD for this.

The ARM world needs to make its peripherals discoverable. It is a pain in the ass that every little variant of an ARM board needs its configuration "upstreamed" because there's no way to reliably find it by running some generic code on the thing. Bonus points if they come up with something sane instead of adopting EFI.

Fitbit was a cloud thing before the acquisition. If it isn't OK for Google to collect that information, it wasn't OK when Fitbit did it. You idiots enabled this shit when you bought into it.

I'm not concerned about plastic in the hands of DIYers. The material is fiberglass. Click the link for more information. The other half of the comment is about the plastic component: The erosion into microplastic is mostly an indirect problem because it comes back to us through the food chain. You don't dump your plastic wrappers in the woods to enable new habitats, do you? Then don't claim that plastic composites should be used as wildlife habitats.

Sorry, no, the old blades should be professionally burnt, not reused, especially not disposed of as "habitats". They are made of plastic, which will not rot but erode into microplastics over time. We can do that with wood and metal structures, which will be microbially consumed or rust away, but not with plastic. Giving large swaths of fiberglass material into hobbyist hands would also be a grave mistake. Working with this material requires precautions that hobbyists will throw into the wind. They will damage their health.
