because i run ctags in one directory (usually the top level or close to it)
and stay there.

i generally run e.g. python3 fu/alu/test/test_pipe_caller.py or something.
constantly doing "cd" i find very annoying.

to find previously-run commands is a matter of running "history" followed by

this saves typing the command out repeatedly - also very annoying.

lots of annoyingness... :)

yep.  it will result in test output that, on return as the ordinary user,
you will not be able to overwrite.  to "fix" that, do this:

soc/src$ sudo bash
soc/src# chown -R colepoirier .
soc/src# exit

that will ensure that all files are owned by you (not root) in the entire soc
locally checked out repository.

a "dumb" way to achieve the same effect is to completely destroy the entire
checkout.  this is wasteful of both time and bandwidth.

> I cd to the top level and run either `python3 setup.py test` or `nosetests`.

this runs every single test, which consumes a lot of time however is a good

to get a "faster development cycle" i tend to run only the test that is needed.
delays in that cycle - by running tests that have nothing to do with the task
hand - i also find annoying.

however *after* that fast-iterative cycle (explicitly running only the relevant
test), it is kinda important to run more (nosetests3, python3 setup.py test)
to make absolutely sure you didn't break anything unrelated.  don't tell no-one
i tend not to do that very often... :)
