Ruby change keys of a hash with a hash map.
ages = { "Bruce" => 32, "Clark" => 28 }
mappings = {"Bruce" => "Bruce Wayne", "Clark" => "Clark Kent"}
Hash[ages.map {|k, v| [mappings[k], v] }]

Shell stdout and stderr fancy tricks
Redirect stdout and stderr to a variable (so you can handle an error without printing to the console)
ERROR_MSG=$(redis-cli PING 2>&1)
Redirect only stdout to a variable
ERROR_MSG=$(redis-cli PING)
Redirect a whole block of commands to not print
{
ERROR=$(redis-cli PING)
} >/dev/null 2>&1

Aeramor / retroactively gitignore
Created July 29, 2013 19:31
Remove any files from the repo that are in the gitignore, even after the fact. Just copy paste the whole thing into terminal/commandline (in the correct directory) and it will un-track the files (but leave them intact locally).Then use git status to verify nothing important was removed.
(GIT_INDEX_FILE=some-non-existent-file \
git ls-files --exclude-standard --others --directory --ignored -z) |
