Linux - New Video card upgrade

Right after you installed the card. Boot into recovery mode and go to text mode. Remove (or just rename) it:

Code:

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old

Then restart your computer. While you are in the desktop, go to 'Additional Drivers' and install the Nvidia driver.

.profile vs. .bashrc

From "man bash"

Quote:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.

Quote:

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists.

In other words, /etc/profile is run when a user logs in. ~/.bashrc is run for other shells (Ie opening an xterm)

SVN Branching and Merging

A basic well-written tutorial: 

http://nedbatchelder.com/text/quicksvnbranch.html

 More advanced stuff:

1. You branch.
2. Someone else changed T0 on trunk. Sequence in trunk: T0
3. You make the change T1 on your first branch. Sequence in Branch: T1
4. You create a new branch from trunk at T2; it contains change T0. Then you merge your changes from your prior branch (the yellow arc — a Bunny Hop) into your new branch. This brings change T1 into your second branch after change T0. Sequence in your branch: T0, T1
5. You make change T3 in your branch. Sequence in your second branch: T0, T1, T3
6. Someone else makes change T4 in trunk. They committed to trunk first; they win. Sequence in trunk T0, T4
7. You make your third branch, at time T5. It includes changes T0, T4 in that order. You merge all your changes from the previous branch — this means you have to do the merging necessary to make changes T1 and T3 blend in correctly after T0, T4. But you get to do this in a workspace, off of a branch, nicely isolated from trunk. It is usually pretty easy. Sequence in the branch is now T0, T4, T1, T3
8. With no other overlapping changes between when you cut this branch and now (between T5 and T6), you merge your branch into trunk. Because all of the changes in this branch take place after the already committed changes in trunk, the merge goes smoothly.

Linux Lost Internet Connection

Linux renew ip command

The -r flag explicitly releases the current lease, and once the lease has been released, the client exits. For example, open terminal and type the command:
$ sudo dhclient -r
Now obtain fresh IP:
$ sudo dhclient
There is no need to restart network service. Above command should work with any Linux distro such as RHEL, Fedora, CentOS, Ubuntu and others.

On a related note you can also try out the following commands:
# ifdown eth0
# ifup eth0
# /etc/init.d/network restart
OR
# /etc/init.d/networking restart

OR

 $ sudo dhclient eth0
