i think git is frowned upon because porting it would be a massive effort due to
its many dependencies, whist python has been ported and mercurial just works.

i am pretty sure nemo’s octopus window system in planB had a way to save and

another.

i would have thought/hoped that windows would remake the cifs session when
windows comes out if standby, using cached credentials, so other than being a
bit slow to start, cifs to the plan9 server should come back.

the most significant change that plan9’s c made (that i can think of) is
compile time type checking between modules /files.
this helps but is not a huge improvement to safety.
the main reasons plan9’s kernel is fairly safe is its clean and simple design,
which makes problems less likely.
