Ubuntu Linux Tips : Close Not Responding Windows with xkill

Ever experience application freeze in Linux? You can easily spot them because their windows are not responding and it has blank content. Non-Responding application also eats up your memory and your precious CPU cycle. Some even prevent you from running other critical applications.

But how are you going to close a non-responding application? Clicking the close button surely won’t help because the application does not response to your mouseclicks. For some people, the solution is to quit Xwindows (GNOME) session and start it again, but that would consume too much time by re-initialising the Windows Manager back.

One thing that you can do that actually can help you eliminate non-responding application is by using the ‘xkill’ application. To use it, (either in GNOME or KDE) you need to press Alt-F2, and type xkill to run the app. Your mouse will turn into something that resemble skull bone. Click on the non-responding Windows, and the windows will be forced closed.

There you go, a not so subtle solution to non-responding windows in Linux.

Funny how this guy solve his problems by utilising excess hardware in this manner, creative indeed.

This inspires me to come up with simpler solution when I come accross such problem like this. Sometimes , the toughest problem does not always require an uber-1337 solution.

ffmpeg – How to Convert AVI video files to 3gp for phone

I know some people love to store their favorite movies or video clips in their phone (especially nokia phones). Here’s a quick how to, to convert movies and video clips to a format suitable for use in mobile phone.

For this thing to work, we will be using the multipurpose encoder/decoder – ffmpeg.

Convert from MPG to 3GP
ffmpeg -i video_clip.mpg -s qcif -vcodec h263 -acodec mp3 -ac 1 -ar 8000 -ab 32 -y clip.3gp

Convert from AVI to 3GP
ffmpeg -i video_clip.avi-s qcif -vcodec h263 -acodec mp3 -ac 1 -ar 8000 -r 25 -ab 32 -y clip.3gp

Convert from 3GP to AVI
ffmpeg -i clip.3gp -f avi -vcodec xvid -acodec mp3 -ar 22050 file.avi

With these method you wont need to spend a dime on expensive proprietary encoder anymore to transfer your favorite music files into your phone.

It should be noted that, the ffmpeg package from the default installation in Ubuntu are pretty useless for practical purposes. Please read this to enable 3gp encoding in Ubuntu : Enable mp3 and amr support in ffmpeg ( Ubuntu )

Listen to free OGG stream Internet Radio on Ubuntu Linux

Sometime, in the middle of the night, I like to listen to music while working on the computer, hacking codes or plain writing blogs on my Linux desktop.

Because of my Linux desktop default installation ‘discourage’ me from listening to MP3 streams, so I’ve to find alternative Internet radio that uses the free OGG Vorbis streams.

So far I found that Xiph Streams directory is the best internet radio directory that can be found on the internet. It feature collection stations dedicated for certain genre of songs, such as blues, hard rock, dance, alternative rock, jazz and few others.

The streams is playable on Totem Player, XMMS, Rhythmbox, and almost all music player available for the GNU Linux operating systems.

FYI, I’m currently listening to a radio station which plays oldies songs. :)

Search Ubuntu Edgy Eft package from Mozilla Firefox

Have you noticed that the Mozilla Firefox build of Ubuntu has an extra search plugin that lets you search for Ubuntu Package Repository? I have, and sometimes I miss the functionality much if for some reason I had to use other operating system to do my work.

I need the search plugin because sometime I want to quickly check the Ubuntu software repository for certain packages while surfing the internet.

So to make things easy for me, I extracted the search plugin directly from my Ubuntu Linux installation and made it available for download. Now everybody can use this plugin to search Ubuntu Edgy softwares even if they are not using Ubuntu.
