Looks like latest Android/NothingOS is taking inspiration from Windows.
The wifi is broken and the search bar now asks to search the net before filtering my apps list.
How does this shit get past the most basic of checks.

The amount of national newspapers stating the maccies Big Tasty is being _upgraded_ to 1/4 pounder patties from 1/3 shows how much oversight AI writing is getting.

This idea for a RISC-V machine similar to RC2014 seemed like a good one so I've been thinking about it for the last few days.
I've put together a rough plan for how it might be done - I'm interested in what people think!
