Aesthetically editing grub.cfg
EDIT: (for clarity) I'm looking to change the appearance of the grub boot menu, by editing the configuration files (possibly but not necessarily grub.cfg). So, any ubuntu user knows how filled up the boot menu gets after a few kernel upgrades. Back in the days of menu.lst, you could tweak the menu …
Why does my MagSafe power connector only work one way round?
It's not a major problem, just a little niggle, but just lately the MagSafe power connector on my white 13" MacBook only seems to charge one way up. Previously it didn't matter which way up it was. Anyone any (sensible) suggestions as to why this might be?
How can I remove duplicate files across separate directory trees?
I have two directories: and . Some of the files in are duplicates of those in . Some merely have the same name, and a few may even have identical content but different names.

During just last year, I've had: two broken 500GB Seagate hard drives; one was new, broke completely, got different one - refurbished, but a little bit broken too (after running for a little while it just hangs) new 1TB Seagate hard drive that is semi-reli…
Prevent display from turning off due to inactivity when watching full screen video (windows 7)
In power options the monitor is configured to turn off (go to power saving mode) after 10 minutes of inactivity. The problem is it also turns itself off when I watch long YouTube videos in full screen. I like power saving, so the default behavior is OK, but it shouldn't kick in when I watch fullscr…

If a computer is connected to internet via wireless and lan both, which way Internet traffic would flow?
How does this actually work? How different ip addresses on ethernet adapter and wireless adapter are handled for internet data? I know these ip are translated in NAT table but the whole process involving ethernet and wireless adapter together is not clear to me.
Is it possible to have Google Chrome always open shortcuts in a separate window?
If Chrome is already open, it opens new sites (e.g. from Windows shortcuts, application shortcuts, or from the Run dialog) in new tabs of the existing instance. I'd prefer to open new sites in a separate window (a new instance of Chrome). I don't see that in the options - is it possible?

VMware Player loses internet connectivity
Periodically, the internet simply stops working in my virtual machine, and the only way I can get it working again is to restart the host computer.
