Why are apps so slow initially when switch to them, even though I have free RAM?
On my Windows 7 (64-bit) PC, when I have a few resource hungry programs going, and half a dozen others, when I switch to an app that I haven't used for a while, it takes a long time to respond and I can hear the hard drive working a lot.

Check wireless card manufacturer and model in Linux Mint 11

Is there a way to jump to an earlier part of a command line command in the Mac Terminal?
I'll often find myself writing out long commands in the bash shell - things with many arguments, web addresses, routes, etc and so on.

Prettier text dialogs in OS X scripts
I'm getting pretty sick of these default AppleScript and cocoaDialog dialogs: I'd like to replace them with something closer to this: Has anyone made a shell executable like cocoaDialog with a custom look for windows?

How do I count the total number of words of all files in a directory (and its subdirectories)?
I am thinking I can do this with wc somehow, if there was a recursive option but I am not sure. I want a grand total of the total number of words in the files under a directory and its subdirectories (not just a per-file word count). Note I am performing this with my mac. Ok, I just tried this comm…

I was wondering: What's the difference between shutting down the computer and shutting down the hard disk? Aren't they the same thing? That is: I can't use the computer if the hard disk is shut down. If I shut down the computer, isn't the hard disk shut down along with it too?
