For quite some time creating proper video-tutorials with Linux wasn't very comfortable.
I tried it with Cinelerra before, but since it's a fully featured video-editor it's too blown up for this simple task. Other solutions, like for example VNC2SWF only record video, but no sound.
Recently I came across the command Ctrl-R in the bash shell. It allows you to search and browse your bash history.
For instance you ssh into your server every day, in between each ssh you do a bunch of other things, this makes in impractical to use the Up arrow key to go through your history to find the command. Instead hit Ctrl-R, and start typing ss, it will search your bash history for the last time you used a command with ss in it:
During the last couple of days I stressed my internet-line a little and downloaded some CD-images. One of these was Nexenta GNU/OpenSolaris Alpha 6.
I didn't have much experience with Solaris before and it also wasn't very good, because on the Solaris 9 machine we have in the office I missed quite some comfort which I'm used to from Linux.
I guess we all remember Jurassic Park, and especially one feature of this movie: The "Unix-system" with that cool 3D file-browser. Well that file-browser was SGI's 3D File System Navigator, which also helps us to know what that "Unix-system" really was, Irix.
We all know that CDs don't live forever. Often loss of data is predictable when the disc is starts to take longer to read, but these changes in speed are often enough too small to be noticed or something else (like the overall system load) is taken responsible for it.
