How many times have you reinstalled your machine? I know I long ago lost count. It isn’t that it is unreliable but, in my case, I often upgrade to new versions or reinstall to test things out. How nice would it be if you could clone your current installation and fairly easily reinstall to just about the same stage you were before you changed? This post will tell you how!

Yes, it is mplayer. And it is pretty much command line, and it is much much powerful then the wrapper GUI front end.

I have not master this great movie player, I just have use it to watch a french movie, which the english subtitle I obtained do not sync at all. If you face this, no worries, because with mplayer, you can forward or backward the subtitle by pressing your keyboard. For me I still enjoy the movie which I would not enjoy so much if I have no subtitle.

Although it is getting harder and harder to run out of disk space, some of us still manage to do it. Whether it's yesterday you had all the space in the world and today you have nothing or the space just dwindled away over time doesn't really matter: you need to either add a bigger disk or get rid of some of the junk.

If this was sudden, you should check a couple of obvious suspects: /tmp files, log files, and device files that got accidentally removed and thus became ordinary files when something writes to them. If the device were a tape drive or another disk, you could be writing a lot without realizing it.

Don't blindly delete large log files without at least doing a "tail": the contents may alert you to a ongoing system problem.

Finding large files

Each distribution has some specific tools to build a custom kernel from the sources. This article is about compiling a kernel on Debian Sarge systems. It describes how to build a custom kernel using the latest unmodified kernel sources from www.kernel.org (vanilla kernel) so that you are independent from the kernels supplied by your distribution. It also shows how to patch the kernel sources if you need features that are not in there.

I decided for my reference and by requests of various people, that I would write a full installation tutorial for Ubuntu with all of the cool features of XGL and Beryl on the T60. The cool thing about Ubuntu is it installs and configures a lot of your drivers for you (including wireless) so it is fairly painless to get everything up and running. I wrote this tutorial dual-booting Windows XP with my T60p (2007-93U).
