If I could offer one correction, it would be that SBU (as specified by the USB 3.0 Promoter Group[1]) means "Sideband Use" rather than "Secondary Bus".
On some devices, it is used to carry UART; on others, audio.
I’ve noticed most of the replies to your comment address the first half, and none (as of right now) address the second:
> So the question that comes to my mind is whether this is yet further new and different Raspberry Pi 5 hardware that comes with no software or prospect of software.
If by “this” you mean the MicroSD Express hat from the article: this is a hobby project produced by a hobbyist, who seems to have no plans to sell or mass produce it.
It is unfair to the creator for you to lump it in with, and draw a conclusion from, the works produced by Raspberry Pi Holdings.
If you can turn the port off and then back on remotely, perhaps you can skip the unplugging part completely? I know that some managed PoE switches even offer a button to power cycle a port.
> you can just manually make any letterform 2x width,
Yes. Any glyph may be wider than its advance. The advance, however, must remain the same across all glyphs. If it does not, the font is not monospaced.
The passage you’ve quoted refers not to the width, but to the advance.
The TL;DR is that Windows 3.1 effectively replaced DOS and acted as a hypervisor for it, while drivers could be written for Windows (and many were) or DOS (and presumably many more of those were actually distributed). The latter category was run in hypervised DOS and the results bridged to Windows callers.
(Edited after submission for accuracy and to add the Old New Thing link.)
It seems as though the maintainer moved it into an external plugin because they were told, loud and long, that “shoving AI [there] [was] totally the wrong idea.”
It’s certainly an example of how public backlash can change the discourse, but it is not an example of why it was wrong to put AI there.
It’s fully possible that I’ve missed something, but it doesn’t appear to be proprietary to me.
