This simple and brief tutorial will show you how to install the Lock Keys indicator in Ubuntu using ppa. If your Ubuntu laptop doesn’t have any LED indicators for the lock keys, it may be useful. The indicator displays notifications on top-right corner when you press on Lock Keys and the applet on top-panel shows you whether your caps lock, num lock, or scroll lock keys are on.
You can set it to show the indicator when lock key is inactive.

The keylock indicator daily build ppa provides latest packages for Ubuntu 12.10 Quantal, 12.04 Precise and 11.10 Oneiric.
Hit Ctrl+Alt+T to open terminal, then run following 3 commands to install it from the ppa repository:

How to Disable Apps Running In The Background in Android



If you ask any Android expert for the solution to fix a slow phone, one of the answer you will receive is to uninstall the unnecessary apps so they won’t run in the background. But what if you need an app to be installed (even though you are only using it occasionally) and yet preventing it from running in the background?
One solution is to make use of a Task Manager and kill the background running app regularly. Alternatively, you can disable the app totally so it won’t (and can’t) be running in the background at all.
Here’s how you can manually disable apps from running in the background without your permission.
Note: This trick will only work in selected phone. It does not work in the stock Android in the Nexus device.
1. Go to the “Settings” section in your phone.
2. Scroll down and go to Applications manager.

3. Swipe from right to left until you reach the “All applications” tab.

4. Now, tap on the app you want to disable from running in the background and it will show you two buttons: Disable and Force Stop. Tap on Disable.

It will ask you for confirmation whether you want to disable the app, just tap OK.

And you are done. Now, the app will not run in the background even if any other application tries to execute it. If you want to enable it, just follow the same steps. However, one thing you should note here is that if you disable any application, it will disappear from the App Drawer and will not be available till you enable it again. You can also use the Force Stop to temporarily stop the app from running.

CrunchBang Linux 11 R20121015



Philip Newborough has announced the availability of a new development build of CrunchBang, a lightweight Debian-based distribution featuring the Openbox window manager: "It has been approximately three months since the previous 'Waldorf' images were built, so I figured the time was right to upload some updated builds. To be honest, I was tempted to wait until Debian 'Wheezy' migrates to stable before updating the builds, but Debian being Debian (released when ready), it could mean waiting a week, a month, or even a year. Anyhow, the new images contain some fixes to the installer that affected installations performed using DVD media. Personally, I tend to install via a USB stick, so I had not come across the bug myself, until somebody else mentioned it. The bug appeared as an error message just before the GRUB install screen, where it asked the user to insert an additional disk." Here is the full release announcement listing the most notable changes. Download (MD5): crunchbang-11-20130119-amd64.iso (751MB, torrent).
