The Linux kernel process scheduler, as you know it, has been completely ripped out and replaced with a completely new one called Completely Fair Scheduler (CFS). How fair it will be, remains to be seen, but in the meantime here's what its original creator Ingo Molnar has to say on the subject:
80% of CFS's design can be summed up in a single sentence: CFS basically models an "ideal, precise multi-tasking CPU" on real hardware.

While GNOME registry size isn't nowhere near the size of Windows registry, and thus shouldn't slow your computer too much, it's still nice to have a tool that cleans unused and obsolete entries.
OK, this is so cool and sexy, I really don't understand how I didn't find about this earlier. Possibly because it's the recent add-on to the well known script utility?
So, I suppose you all know about script. You type script, do your work, type exit, and you have your complete session logged in the file named typescript. Quite handy if you want to log everything you did in the shell for whatever reasons.
Although this may seem like a small catastrophe to you, it's actually very easy to recover from that situation. What you need to do is to reboot (power on) your system, but on the LILO prompt you should type something like:
LILO: Linux init=/bin/sh rw
Where Linux is the example image name, you should supply the actual data, of course. And same parameters should be provided to GRUB or any other boot loader you might use.

Suddenly, you need to update the BIOS on your motherboard to support some new piece of hardware, but typically the motherboard vendor is offering only DOS based BIOS flash utilities. You panic! Fortunately, this problem is easy to solve...
