These are a view things that i had looked up to solve some problems and i plan to update this post regularly…
To push a new branch to remote
git push origin new_branch
To delete a remote branch
git push origin :new_branch
To push new tags
To delete a remote tag
git tag -d 12345
git push origin :refs/tags/12345
To reset a local branch to exactly match a remote branch
git fetch origin
git reset --hard origin/master
To abort a rebase
Changing the origin of your git repository (relocate the repository)

In case you need a MySQL schema transferred from one host to another and the schema names differ, you can ran into problems with a standard MySQL dump.
Use the following statement to create a schema dump that contains all table and view definitions as well as all stored procedures without a reference to the original schema:
mysqldump -uroot -p name_of_the_original_schema --no-data --opt --routines | sed 's/`name_of_the_original_schema`.//g' > dump.sql
The dump will only contain the schema definition and no data. Calls to routines will not be prefixed with a schema name.

4 years ago i had a first iTunes terminal tipp, here is a round up (all terminal tipps require Mac OS X):
Invert the iTunes Store links in the list
The littler arrows can either point to the iTunes store or to the same artist or album in your library. Invert their behavior to let them point to your files instead of the store:
defaults write com.apple.iTunes invertStoreLinks -bool YES
Undo this with
defaults write com.apple.iTunes invertStoreLinks -bool NO
Disable them with
defaults write com.apple.iTunes show-store-arrow-links -boolean FALSE
Enable them with
defaults write com.apple.iTunes show-store-arrow-links -boolean TRUE
Restore the horizontal stoplight
Again, Apple messes with it’s own UI guidelines. To restore sanity, use
defaults write com.apple.iTunes full-window -boolean TRUE
Reenable the vertical layout introduced with iTunes 10 through
defaults write com.apple.iTunes full-window -boolean FALSE
Enable half-star ratings
The following will let you rate your songs with half-star ratings (i.e 3.5 stars):
defaults write com.apple.iTunes allow-half-stars -bool TRUE
If you don’t like the fact, that the half-star ratings will round on any i* device, turn it off again:
defaults write com.apple.iTunes allow-half-stars -bool FALSE

Just a quick reminder for myself: You need to enable wake-on-lan on the nic in most linux distributions via ethtool.
If your nic supports WOL, it probably needs to be enabled in your computers BIOS first.
Most WOL tools use the “MagicPacket(tm)” method, so the right command to enable it on the nic “eth0″ would be
This is not a persistent setting and it is gone after a reboot. Most tips around recommend creating a runlevel script for executing this command after boot or before shutdown.
I’ve added the command as a hook in my network scripts:
auto eth0
iface eth0 inet dhcp
pre-down ethtool -s eth0 wol gYou can also use post-up. I like this method because i tend to forget about my runlevel scripts and so i keep the network stuff in one place 
If you are a debian user, you maybe need to stop your system from turning off the nic on HALT. To do so, add
to “/etc/default/halt”.

I found no other way to change the path of “images” in a Rails application than monkey patching the AssetTagHelper like so:
module ActionView
module Helpers #:nodoc:
module AssetTagHelper
def image_path(source)
compute_public_path(source, 'static_images')
end
alias_method :path_to_image, :image_path # aliased to avoid conflicts with an image_path named route
end
end
