This repository is shared for group of developers and all who have ssh access onto internal.bokov.net shall have right to commits onto git repository. So first of all prepare place for git repo at new hosting :

ssh user@internal.bokov.net
cd var
mkdir git_repo
chmod 777 git_repo
cd git_repo
mkdir my_project
cd my_project
git init --bare --shared=all
cd objects
chmod g+ws *

Next clone existing repo and change its settings to point onto internal.bokov.net

git clone --bare git@github.com:bokov/github_project.git
git remote add -t master -m master origin ssh://internal.bokov.net/var/git_repo/my_project/
git push origin master

to start work with new repo just use

git clone ssh://internal.bokov.net/var/git_repo/my_project/

have fun.

A “Justification Review Document,” which has oddly been deleted from Google since I found it but is still available at this cache link, explains that, “the new PS3s will be placed in a cluster environment with an existing cluster of 336 PS3s by connecting each of the units’ one gigabit Ethernet port to a common 24 port gigabit hub.”

1) Remove openjdk, gij
apt-get remove openjdk-*
apt-get removel gij-*

2) Install good one java powered by Sun
apt-get install sun-java6-jdk

3) Install EC2 API
cd /home/abokov/
http://s3.amazonaws.com/ec2-downloads/ec2-api-tools.zip
unzip ec2-api-tools.zip

4) Configure environment : add this lines onto the end of ~/.bashrc
#ec2 deal with stuff
export JAVA_HOME=/usr/lib/jvm/java-6-sun
# setting up Amazon EC2
export EC2_HOME=/home/abokov/ec2-api-tools-1.3-30349
