The uptime command on Linux shows 3 numbers for the CPU load on the system. The first number is load in last 1 minute, next is 5 mins, and then 15 mins.

1.0 means cpu is loaded 100%. 2.0 would mean there twice as much load as the CPU can handle, or while 1 request is processing (assuming 1 is the max work CPU can perform at 100% usage), then 1 is waiting in a queue.

The mysql-dev package (to provide mysql APIs) is called ‘libmysql++-dev’ on Ubuntu. Install with:

<code>sudo apt-get install libmysql++-dev</code>

Ading new repositories:

<code>$ sudo mkdir /home/svn
   $ cd /home/svn
   $ sudo mkdir myproject
   $ sudo chown -R www-data:subversion myproject
   $ sudo chmod -R g+rws myproject

#make repo
 $ sudo svnadmin create /home/svn/myproject

#start svn server - --foreground keeps output in foreground for debugging server activity
svnserve -d --foreground -r /home/svn

To configure access to to the new project, edit the /home/svn/myproject/conf/svnserve.conf file created by default and uncomment the password-db line. Save the file.Edit the passwd file in the same dir and add a user and password to access this project.

Start the server with the svnserve command

Once the server is started, you can connect to the repository using a SVN client in Eclipse like Subclipse. Connect to the repository using svn://address/myproject as the project URL and root.

To add a new source project from Eclipse into the repository, select Team… Share Project. ‘Add to Source Control’ for each of the dirs in the project, and then ‘Commit’ the files.

# sudo addgroup <groupname>

To add a new user to a existing group:

# sudo adduser <username> groupname
