About Git
Git is a distributed version control system released to the public in 2005. The program allows for non-linear development of projects, and can handle large amounts of data effectively by storing it on the local server.
This tutorial will cover two ways to install Git.
How to Install Git with Apt-Get
Installing Git with apt-get is a quick and easy process. The program installs with one command:
sudo apt-get install git
After it finishes downloading, you will have Git installed and ready to use.
How to Install Git from Source
If you are eager to download the most recent version of Git, it is generally a good idea to install it from the source.
Quickly run apt-get update to make sure that you download the most recent packages.
sudo apt-get update
Prior to installing Git itself, download all of the required dependancies:
sudo apt-get install libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev build-essential
Once they are installed, you can download the latest version of Git from the google code page.
wget http://git-core.googlecode.com/files/git-1.7.12.rc2.tar.gz
After it downloads, untar the file and switch into that directory:
tar -zxf git-1.7.12.rc2.tar.gz
cd git-1.7.12.rc2
If you want to do a global install, install it once as yourself and once as root, using the sudo prefix:
make prefix=/usr/local all sudo make prefix=/usr/local install
If you need to update Git in the future, you can use Git itself to do it.
git clone git://git.kernel.org/pub/scm/git/git.git
How to Setup Git
After Git is installed, whether from apt-get or from the source, you need to copy your username and email in the gitconfig file. You can access this file at ~/.gitconfig.
Opening it following a fresh Git install would reveal a completely blank page:
sudo nano ~/.gitconfig
You can use the follow commands to add in the required information.
git config --global user.name "NewUser" git config --global user.email newuser@example.com
You can see all of your settings with this command:
git config --list
If you avoid putting in your username and email, git will later attempt to fill it in for you, and you may end up with a message like this:
[master 0d9d21d] initial project version
Committer: root
Your name and email address were configured automatically based
on your username and hostname. Please check that they are accurate.
You can suppress this message by setting them explicitly:
git config --global user.name "Your Name"
git config --global user.email you@example.com
After doing this, you may fix the identity used for this commit with:
git commit --amend --reset-author

memcached:
PHP extension for interfacing with memcached via libmemcached library This extension uses libmemcached library to provide API for communicating with memcached servers.
Newer Project.
Newer Features.
Faster.
memcache:
Memcached is a caching daemon designed especially for dynamic web applications to decrease database load by storing objects in memory. This extension allows you to work with memcached through handy OO and procedural interfaces.
Mature Project.
Binary not dependant on the libmemcached library.
Support for more legacy code.
I will add the optional php5-memcached line into the post as well so people will know they have the choice.
btw, which is your recommendation? memcache or memcached?
However I have read memcached being newer has a performance advantage over memcache. Honestly I have never done any benchmarks so I can not prove this one way or the other.
I would suggest looking at these posts for a little more information between the two it seems to me at this time it’s basically up in the air if either has a true advantage over the other at this time unless the application being hosted takes advantage of the newer features contained in memcached.
