Unp is a small perl script which makes extraction of any archive files a bit easier. It support several compressors and archiver programs, chooses the right one(s) automatically and extracts one or more files in one go.
Instalation:
sudo apt-get install unp
Usage:
usage: unp file [file]...
file: compressed file(s) to expand
Use -- to pass arguments to external programs, eg. some tar options:
unp fastgl.tgz xmnt.tgz -- -C /tmp
Special option:
-f Continue even if program availability checks fail
-u For Debian packages:
- extract data.tar.gz after each operation
- extract control.tar.gz in control//
For other archives:
- create directory /
- extract contents there
currently supported extensions and formats are
tar[.gz,.bz2], gz, bz2, Z, ar/deb, rpm, shar, rar, arj, zip, LHa, cab, ace,
tnef, uu (mail, news), mime, hqx, sea, zoo, pmd, cpio, afio, lzop
Problem:
It doesn’t extract files from RAR archives with full path!

SSHMenu is a GNOME panel applet* that keeps all your regular SSH connections within a single mouse click.
To install it on Ubuntu, add this entry to your /etc/apt/sources.list:
deb http://sshmenu.sourceforge.net/debian stable contrib
Then you have to import the repository key:
gpg --keyserver subkeys.pgp.net --recv-keys 4CC00851
gpg --export --armor 4CC00851 | sudo apt-key add -
Run:
sudo apt-get update
and then:
sudo apt-get install sshmenu-gnome

Set Drivel to Post to Your WordPress Blog

Drivel is a nice blog editor for Gnome. To install it on Ubuntu, run this in your terminal:
sudo apt-get install drivel
Now you need to configure Drivel to connect to your blog. Go to Applications -> Internet. Select Drivel Journal Editor.
When the dialog box appears, input your username and password into the first two textboxes. For Server Type, select Movable Type from the dropdown. Now the tricky part, for the server address you will need to enter the full path to the xmlrpc.php file on the server (for example http://www.yourdomain.com/yoursubdirectory/xmlrpc.php). Check the Remember password checkbox and the Automatically login checkboxes (if desired) and click the Log In button.
Happy posting!

3. The Google Earth Setup window opens, if the default installation paths are fine to you, click ‘Begin Install’
4. The program installs itself and when it has completed click ‘Start’.
Advanced mode (using Medibuntu repository):
1. Add Medibuntu to your sources.list, as well as its GPG key to your keyring. Make sure to use the correct sources.list that corresponds to your current distribution:
Ubuntu 6.06 “Dapper Drake”:
sudo wget http://www.medibuntu.org/sources.list.d/dapper.list -O /etc/apt/sources.list.d/medibuntu.list
Ubuntu 6.10 “Edgy Eft”:

Installing NoMachine NX on Ubuntu 7.10

NX allows you to run remote X11 sessions even across slow or low-bandwidth network connections, making it possible to start sessions from clients running on Windows, Linux, Mac OS X and Solaris platforms to servers running, at present, on Linux or Solaris. Note that development for extending server support to Windows and Mac OS X platforms is in progress.
NX, thanks to exclusive X protocol compression techniques and an integrated set of proxy agents, improves the power of the X Window System to transparently run graphical desktops and applications through the network, by reducing round-trips and implementing strict flow-control of data traveling through low-bandwidth links. Even on slow or low-bandwidth network connections, you can get impressive performance thanks to NX’s lazy encoding algorithm and NX’s capability to automatically tune itself to network bandwidth and latency parameters.
Moreover, NX also can connect to remote RDP and VNC servers, relying on the rdesktop and TightVNC clients by encapsulating the RDP or RFB session within the X11 session.
Here’s a screenshot:

Session shadowing
Desktop sharing
An X11 session
Look at the screenshots below to find out how to get started with NX:
First download the files for the server from here.
For Ubuntu, use NX Free Edition for Linux DEB – i386.
You’ll need to download three files: client, node and server.
Change your working directory to the location where you saved the package and install it by running from a console:
For detailed instructions on how to install the NX Client, NX Node and NX Server packages, please look here.
sudo dpkg -i nxclient_3.1.0-2_i386.deb
sudo dpkg -i nxnode_3.1.0-3_i386.deb
sudo dpkg -i nxserver_3.1.0-2_i386.deb
After installing the server, on your Windows computer, download nxclient for Windows and install it.
Once it’s installed, run it, and enter the IP address of your Linux computer to connect, give it a session name for your own reference, and choose your connection speed.
Here you can download the manual or you can view it online here.
