Re: [Ilugc] Check you DNS
The root DNS servers provide the NS for the TLD and the first level
sub domains under each TLD.
If a domain name is not cached then the NS records are fetched
starting @ the root servers. The file root.hint in bind
installation is the provide the IP numbers for the root servers.
Okay I did not know that it comes with a preloaded set of IP addresses.
I just downloaded root.zone to find out the same :-)

[Ilugc] One day FOSS workshop in Sri Durgadevi Polytechnic College, Kavaraipettai
Dear all, One day FOSS workshop was conducted in Sri Durgadevi Polytechnic College, Kavaraipettai (http://www.sdpc.ac.in) on 06/07/12 for the 2nd and 3rd year students of Computer Technology totaling 126 students. The workshop was conducted as 2 separate sessions. A hands-on session was given to all the students to remotely install Ubuntu 12.04 LTS in their desktops. After installation the students were introduced to package management using apt-get / ubuntu software center. An interesting thing to note that, more than 30 students purchased Ubuntu DVDs after the workshop. I would like to thank Mr. Harikumar / Placement Officer and HOD/Computer Technology for organising the workshop. Also, in my recent workshops, I noticed ubuntu's default unity interface attracts students community at large. Now I am currently working on a new project named, Ubuntu Linux Campus to implement Ubuntu GNU/Linux in more than 2000+ technical institutions across Tamilnadu (only the project is named after Ubuntu, and we will be supporting all other major distributions as well, so no distro controversies here). I am sure that this initiative would definitely become huge success if it is well planned / supported. I am very eager to hear from ILUG-C / other community members on this. Regards S.

[Ilugc] mplayer tricks
There are plenty of music players and video players in UNIX. But I love mplayer. I have also done some foot pedal coding with mplayer I/O. But overall I love it for its ability to handle all media,all situations and all output devices. I got to know that mplayer is actually a music player as well from my former colleague several years ago. You could play video in root window(yes), you could also play tv and do several other things. $ mplayer -rootwin foo.flv You can also play streaming audio and video.From Internet radio stations or a video file available using HTTP or RTSP. Actually you could also use it to view webcam and surveillance camera. mplayer also can rip DVDs, play DVDs. You can transcode video using its companion mencoder. You can create a DVD from a bunch of video files. You need dvdauthor after converting the video to mpeg. mplayer can play a song or a playlist in a loop. It also understands playlists, it has support for OSD menus. Which is basically transparent glass like menus invoked with the mouse or keyboard.

The worst thing about it is that one cannot open multiple copies of the same program. Really? In Unity, at least you can open many instances but switching between the windows is little tricky. When the currently focused window is of program A and you want to switch to one of the many windows of program B, clicking the B's icon in the left panel (or using Alt+Tab to traverse to program B) will open the last accessed window of the program. Clicking the icon again will show a tiled view of all the windows of the program and you can click on the one you want. Using Alt+Tab to access the window that was not used last is more painful. You need to traverse to the app using Alt+Tab and press down arrow still holding the Alt key (or keep holding Alt key for few seconds) to get the tiled view of the open windows. May be Gnome 3 also has some similar ways, explore :) And I am used to having icons for all my open programs neatly lined up along the bottom of my screen, and clicking the one I want. Now I have to keep banging on the top right of my screen with the mouse to do that ... I'm used to Alt+Tab even before Unity and Gnome3 came and I find it much easier.
