Make Vim Remember The Cursor’s Last Position After Exiting
So you edit a file in vim, you exit vim, and after a while you want to edit the file again. Many times it’s nice to have the cursor placed in the same position you left it. Here’s how to make this happen:
1. Add this to your ~/.vimrc file (or to /etc/vim/vimrc to enable to the feature system-wide):
if has(“autocmd”)au BufReadPost * if line(“‘\”") > 1 && line(“‘\”") <= line(“$”) | exe “normal! g`\”" | endifendif
touch ~/.viminfo
Move Gnome Panel To The Second Monitor – Ubuntu
Say you have two monitors set up as “extended desktop”, and you want to move the gnome-panel from one monitor to the other monitor.
Here is how to do it in Ubuntu (Tested on Ubuntu 10.04):
1. Right click the panel, choose “properties”.
2. In “General” tab, uncheck “expand”.
3. Drag the panel from its left or right edge to the other monitor.
4. Right click the panel, choose “properties”, in “General” tab recheck “expand”.
You’re done. Have fun 
Found the tip here.
Update:
An easier way, is just to hold “Alt” key, and drag the panel from one monitor to the other. No need to play with the “expand” setting.
NumPad Problems When Using Vim over Tmux
I use vim as my main text editor, and I usually split the screen to edit a few buffers in parallel. To make resizing the windows faster, I mapped the numpad keys “/*-+” to resize the windows (see original vim tip here).
Recently, I started to use tmux, and opened vim, split the windows as usual, and tried to resize them. It didn’t work 
I use Ubuntu 10.04 (Don’t remember the exotic name..), and I found that the latest tmux package in their repo is 1.1-1.
Anyway, version 1.1-1 has a bug with the NumPad. The solution is to download the source of tmux 1.2 and build it. It depends on libevent so you’ll need to get it first:
this is how to make it work:
1. sudo apt-get install libevent-dev
2. Get the source tarball of tmux from here.
3. tar xzf tmux-1.2.tar.gz
4. cd tmux-1.2
5. ./configure
6. make
7. sudo make install
Done. Now your life is better. Have fun
