Making your own keyboard app-launcher in Ubuntu

One day I got this message in gmail ubuntu-id mailing list that someone requested a how-to add a keyboard app-launcher in Ubuntu. i tried to give him a closer solution, by pressing Alt+F2 and typing application name; or by adding deskbar to main panel, pressing Alt+F3, and then typing three fore-letter of the application you want to run.
is there simply just one shortcut for all these?

Yes, there is...

1. Go to terminal, run :
gconf-editor

2. In Configuration Editor window, Go to apps/metacity/keybinding_command.
click command_1, and click it once at the it's "value" column, type the application you want.
for example openoffice writer, which the command is ooffice -writer.
then press Enter.
you can also use other command_(1 to 12) that still has no value.

3. Go to apps/metacity/global_keybinding.
Find run_command_1, dan click it once at it's "value" column.
Add your own shortcut, which is not have used before. for example Ctrl+Shift+F5. Type it like this <Ctrl><Shift>F5
Close the Configuration Editor window.

4. Now try pressing Ctrl+Shift+F5.

Hey you, Linux Lover, have you played Crazy Penguin Catapult yet? Yes, it played The Tuxes as a platoon of soldiers trying to fight against a bunch of dirty bears and rescuing their friends. There are more 30 level that you have to pass to conquer this game.

Crazy Penguin Catapult is a flash based game that very funny and quite entertaining too. It took me about an hour to get drown playing this game and forgetting anything.

Add Local Mirror to Repository (Part 1 of Updating Ubuntu from Local Mirror)

Getting update for ubuntu is quite really easy, as long as you are connected to the Internet. It would be so much easier if you able to utilise the benefit of local mirror repository nearby, because of it's fast and convenient speed of data download. So, here's the step by step of getting Ubuntu update from the local repository:

1. Go to System/Administration/Software Sources. You will be prompted with admin password to login.


2. In Software Sources window, make sure to activate source code option. Then change the server to the nearest one to your location.

In my case, I choose http://ubuntu.indika.net.id. Click "Choose Server" to go through.

3. Now, it's time to add another local repository mirror. Prepare the mirror list, and add it by highlighting each line, right click it, and choose "copy" option.

4. Go to Third Party Software Tab. Click "Add" button.
Then paste the line that has been copied before. do it exactly the same for another line.
After all mirror addresses are completely added, click the "Close" button.

You will see a window afterward, click "Reload" button

Soon you will see the mirror scanning in progress. You can see the download speed reaching approximately 90 Kbps because of the local mirror location factor. When it's finished, it mean that you have successfully adding local mirror to repository.

The second part of this how-to is a how-to get an update of an ubuntu application from local mirror repository.

Windows's "Safely remove USB" in Linux ubuntu

If you had windows on your machine, you will have to unmount your USB flash disk when you want to plug it off. Just click removable drive icon on the system tray, then click the "Safely remove USB...bla bla". When the icon disappear, then you can plug off the USB flash disk safely.

On different machine of Ubuntu Linux, you will see an icon indicating the presence of your USB flash disk usually on the upper left corner of your desktop. It mean that your USB flash disk is already mounted automaticly. You can browse all of it's content by double-clicking it.

But when you want to "safely remove" it, you must close all running application windows first. Then find and right click the USB icon on the desktop, so you can unmounted it by picking "Unmounted Volume" option. Pretty tricky, huh?

Well, After installing ubuntu, you will not get that kind of easy way of removing removable drive in the Windows desktop, because it's Ubuntu default setting. But you can make it by installing the "Disk Mounter" on the panel. So, here is the trick :


1. Right click the panel, and click "add to Panel" Option.















2. Pick "Disk Mounter" item. then click "Add".



















3. Plug in the flash disk. You will see an icon on system tray at the left side of your panel.



4.When you want to plug it off, just click the icon,and pick "Unmount" option. Now, you can "safely remove" your USB flash disk.



5. The Icon will always be appear even when you have plugged the USB flash disk off. You can check it simply by placing the pointer to it or click the icon.



It's useful when you want to mount it again.




PS. It's my first post in english. I'm sorry for any grammar error or typo. you can give me some suggestion then.
