I never thought I’d say this, but $50 seems kind of expensive for a computer :)
The specs look like the Raspberry Pi 2 which is closer to $30. Me, I’m waiting
for my $9 C.H.I.P. (similar specs) that I Kickstarted to arrive :)
Writing a kernel would be awesome. I’ve been reading Operating Systems Design
And Implementation, “the MINIX book”, which is a pretty clear introduction to
Unix-like OSs, but of course the kernel source code it walks through is a mix
of C and x86 asm, and worse, it’s ten years behind the current MINIX3 kernel
sourcebase. But it could be rewritten in Swift… :) And the great thing is that
if you got the kernel running, you could then drop the whole rest of MINIX on
top of it and instantly have a working BSD-like UNIX with a shell, filesystem,
networking…
