Hi

Identi.ca is an open source social networking and micro-blogging service.
I like Ideni.ca. It’s good service.

I use CLI (command line) everyday. I like to dented from it. It’s simple.
Just install cURL:

$ sudo apt-get install curl

And type:

$ curl -u username:password -d status="message" http://identi.ca/api/statuses/update.xml

You will receive a response containing the XML coding for your post which acts as a confirmation that your post was submitted.

Also you can create a shell file for this
Open a new text document and add the following, save it as identica.sh (or anything ending in sh):

#!/bin/bash
curl -u username:password -d status=″$1" http://identi.ca/api/statuses/update.xml

Make sure you change the chmod to 777 using the following command.

$ chmod 777 /path/to/file/

When you located the file (or add a bash prompt) it makes it simplier to identi.ca the rules. For example you can type the following to command to link to the file.

$ ./path/to/idetica.sh "Message"

Hi

Instead of using a full-blown new virtual X for developing software you can use Xephyr to embed your KDE 4 session into your working KDE 3 or other X11 environment.

If you want to get a minimal KDE session up and running, just launch Xephyr (available in Kubuntu as xserver-xephyr; Gentoo users compile x11-base/xorg-server with USE=”kdrive”):

Xephyr :1 -extension GLX &

You can now launch KDE:

export DISPLAY=:1
/path/to/kde4/bin/startkde &

For other X11 environment just change /path/to/kde4 like:

/usr/bin/startx &

or

/usr/bin/startkde &

or

/usr/bin/startxfce&

You can use “locate” command to find paths like:

locate startkde

Good Luck

Reconfigure an already installed package like gdm.

dpkg-reconfigure package_name

For example you can reconfigure X Server:

sudo dpkg-reconfigure xserver-xorg

Hi
Ubuntu has the root account disabled.
You use sudo to run commands as root. if you need root access for some work:

• To start a root shell, but keep the current shell’s environment, use:

  sudo -s

• To start a root shell (i.e. a command window where you can run root commands), starting root’s environment and login scripts, use:

  sudo -i

There is also a root terminal that is in the Applications menu. You have to right-click to edit the menu’s and add a check to the root terminal in System Tools items.

Don’t forget to type ‘exit’ (or press Ctrl+D) to switch back to your normal user when you are done.
