Taking screenshot of app in BB10 Dev Alpha Device

I was trying to search a nice screen capture application for BB10 Dev Alpha device. I could not find any such application.

But after searching blackberry support forum for a while. I found that there is quite a easy way to take screen shot.

On Dev Alpha device if you press the Volume Up and Volume Down buttons at the same time. It will take a screen shot of whatever currently displayed on screen.

Recording screen acrivity on Ubuntu

Some time we need to record screen activity in video, there are many option in windows but on Ubuntu I found one cool command line utility that can record your screen activity.

Tool is "recordmydesktop", there is also GUI version of it but I found it quite limited in capability. Like I can not record some portion on particular windows. Using this command line tool I can do so and there are quite other interesting feature as well.

To install this tool use "sudo apt-get install recordmydesktop" on command line.

And to start recording particular portion of you desktop, you can use following command.

"recordmydesktop -x 700 -y 180 --width 720 --height 400"

This command will start recording your screen activity, to stop just press CTRL + C on command prompt and it will save recorded video on out.ogv file in current directory.
