Building and installing Git from source on OS X Lion

This outline for building and installing Git has only been tested against Mac OS X 10.7.x (Lion). While these steps may work for previous versions of Mac OS X, I cannot confirm this. Furthermore, you're on your own, if you screw something up, it's not my fault.

If you have Xcode 4, you have Git!

Xcode 4 includes the Git binary at the application level so it's available to itself (located at /Applications/Xcode.app/Contents/Developer/usr/bin/git). Additionally, Xcode 4 includes a new "Downloads" preference pane to install optional components, one of which are the Command Line Tools (similar to the Dev Tools package that shipped with older versions of Xcode) and once installed, Git (and many other utilities, such as make) is installed at the system level (located at /usr/bin).

*Note: You don't have to install Xcode to use the Command Line Tools; it can be downloaded independently from the Apple Developer site (you need to login, but it's free

For each machine running xmodmap will give you the mapping and keycode, take a look first then write the script. I use ubuntu and mac keyboard. The below maps both left and right control and super.

Create an .Xmodmap file in your Linux home directory, with the following contents, then execute xmodmap .Xmodmap

clear control
clear mod4

keycode 37 = Super_L
keycode 105 = Super_R

Install MySQL on macOS Sierra

This procedure explains how to install MySQL using Homebrew on macOS Sierra 10.12

Install Homebrew

• Installing Homebrew is effortless, open Terminal and enter :
  $ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
• Note: Homebrew will download and install Command Line Tools for Xcode 8.0 as part of the installation process.

Install MySQL

At this time of writing, Homebrew has MySQL version 5.7.15 as default formulae in its main repository :

# Kill rails server and guard
bin/spring stop
brew services stop mysql
brew uninstall mysql
brew install mysql@5.5
brew link mysql@5.5 --force
brew services start mysql@5.5
rbenv uninstall 2.3.3
rbenv install 2.3.3
gem install bundle

curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

### And that's all !
# I saw many fighting with finding first commit SHA or similar fancy thing.
# Here we just rely on the GH API, asking commits at 1 per page and parsing the last page number in the header of the reply (whose body only holds the last commit !)
# So this is robust and bandwidth efficient. :)

# If one want the commit count of a specific SHA, just use :
curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1&sha=:sha" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

• XCode is installed (via the App Store)
• XCode command line tools are installed (xcode-select --install will prompt up a dialog)
• Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
