Use the Windows Key for the “Start” Menu in Ubuntu Linux

Linux distributions like Ubuntu open the main menu with Alt+F1 instead of the Windows key that most new Linux       users would be expecting, but it used to be simple to change the shortcut key. Since Ubuntu 9.10 the process isn’t so obvious, but we’ve got the instructions for you.

Just in case you’re a total newb, here’s the menu we’re talking about:

Change the Gnome Main Menu Shortcut Key to the Windows Key

The first thing you’d normally do is head to System –> Preferences –> Keyboard Shortcuts to change out the          shortcut key, but sadly the “Show the panel’s main menu” can’t be assign to the Windows key. You can hit the                     key as much as you want, but it won’t work here.

What you’re going to need to do is either open up a terminal or use the Alt+F2 shortcut key to bring up the Run Application dialog, and then paste in the following:

gconftool-2 --set /apps/metacity/global_keybindings/panel_main_menu --type string "Super_L"

Once you’ve hit the enter key, the Windows key will not only open the main menu, but the Keyboard Shortcuts           panel will be updated with “Super L”, which means the left Windows key.

And there you go.

mageia - open-ssh instalation

As many of you face this problem that if install Mageia from DVD
it wouldn't install openssh properly.
So if type ssh and enter in terminal/konsole it will say "bash: ssh: command not found".
For this You have to do
su
urpmi ssh ssh-server
After this
service sshd start
chkconfig --list sshd
chkconfig sshd on
This will enable you to access you computer from other computer though ssh by ip adress(e.g ssh user@192.168.9.98).

Project ideas for Hadoop

If this is for an undergraduate class, I would suggest something that
allows you to get some work in with basic data structures such as
building an inverted index over a few million documents (maybe Wikipedia
pages?). You will also need to get a general feel for Hadoop.

The University of Washington has some really nice project ideas for
their distributed systems class:

If you wanted to tackle something a little more advanced, then you could
take a look at Pete Skomoroch’s article on finding trends with Hadoop
and Hive:

hive-on-ec2/

http://www.cloudera.com/blog/2009/09/28/grouping-related-trends-with-had
oop-and-hive/

Things to keep in mind:

1.) Hadoop wont be as simple as writing a single Java app
 

2.) There will be some overhead involved in re-writing algorithms in Map Reduce
 

3.) There will also be some overhead involved in setup and maintenance
of the Hadoop Cluster

Take these three things into account when planning how to manage your
time for the project during the semester, semesters can seem a lot
shorter when you spend too much time on things not related to just
implementing and testing your algorithm.

 Good luck!
