Alarm Clock Application for Linux

Posted on June 2, 2008 by Ahmed Tawfik

“Alarm Clock” is a very handy application that I recently discovered in one of my favorite sources of Ubuntu software (getdeb.net), it has the following features:

  1. Resides in the notification area (and can start minimized, i.e. you can easily configure it to start minimized with Ubuntu)
  2. Has many methods of notifications; alarm sound, a simple dialog, and a pop-up in the notification area (what’s called a passive window)
  3. Has snooze functionality
  4. Has a calendar for saving birthdays.

Here are some screenshots that I took for you:

You can get the application from here, Enjoy 🙂

Configuring Java Environment Variables on Ubuntu Gutsy

Posted on May 28, 2008 by Ahmed Tawfik

The default command line interface for Ubuntu Linux is called bash (Bourne Again Shell), and in order to add Java environment variables, we will edit a file named “.bashrc” and add our commands inside, here we go:

  1. Edit the “.bashrc” file by typing “sudo gedit .bashrc” which will open gedit; the famous Linux text editor in Read/Write mode (Note: If you don’t use the keyword sudo to get administrative privileges, then the file will be opened in Read Only mode)
  2. Scroll to the end of the file and add your env. variables as in the following example which I used to define the JAVA_HOME env. variable:
    1. Append this line to the end of the .bashrc file: “export JAVA_HOME=/usr/lib/jvm/java-6-sun” where I point this variable to the location of my default JDK
    2. Save the file and exit and close the terminal
    3. Reopen the terminal and to check that everything went fine, type the following command: “echo $JAVA_HOME” which should result in displaying “/usr/lib/jvm/java-6-sun”, otherwise, repeat the process again, you must have done something wrong.

I really can’t believe what happened :S :S :S, I just downloaded a software called” ophcrack” within my Ubuntu installation, and it could – in less than a minute – find out the password I use for my administrator account on my Windows XP installation on the same machine!!!!
I’m totally paralyzed :S :S :S

To install this software, type “sudo apt-get install ophcrack” and then download the necessary tables to be order to crack the password from SourceForge, load the tables (There are many other tables than the one I’m using, there are even some commercial ones) & have fun :)))) (Don’t forget to read the manual, it’s very useful)
