Latency Comparison Numbers

Note: "Forked" from Latency Numbers Every Programmer Should Know

Event	Nanoseconds	Microseconds	Milliseconds	Comparison
L1 cache reference	0.5	-	-	-
Branch mispredict	5.0	-	-	-
L2 cache reference	7.0	-	-	14x L1 cache
Mutex lock/unlock	25.0	-	-	-

	If the commit you want to fix isn’t the most recent one:

	git rebase --interactive $parent_of_flawed_commit

	If you want to fix several flawed commits, pass the parent of the oldest one of them.

	An editor will come up, with a list of all commits since the one you gave.

	Change pick to reword (or on old versions of Git, to edit) in front of any commits you want to fix.
	Once you save, Git will replay the listed commits.

	git fetch origin pull/2/head
	git checkout -b pullrequest FETCH_HEAD

	OR

	git fetch origin pull/<#>/head:<local_branch_name>

-brew rm FORMULA
-brew rm $(join <(brew leaves) <(brew deps FORMULA))
-Run the last line a until `echo $(join <(brew leaves) <(brew deps FORMULA))` returns nothing OR until the last line informs you that `This command requires a keg argument`.

	brew update
	brew versions FORMULA
	cd `brew --prefix`
	git checkout HASH Library/Formula/FORMULA.rb # use output of "brew versions"
	brew install FORMULA
	brew switch FORMULA VERSION
	git checkout -- Library/Formula/FORMULA.rb # reset formula
