Is it OK to use toothpaste instead of thermal paste when fitting a CPU?
I was told many years ago to do this by someone who at the time knew more than I did. The CPU was a celeron in the Pentium 2 era. It ran cooler with the toothpaste between the chip and the heatsink than what it did with nothing between. Has anyone else ever heard of or tried this? What were the results?
What's causing all the disk activity on OS X?
Occasionally my Macbook Pro will slow down as the hard drive clicks away endlessly. CPU load is low, but applications and menuitems are slow to respond. Is there a utility that can help me determine what's going on, such as the number of bytes read/written or files open/closed per process, over time?
Alt+click-drag window resizing on a Mac? (Similar to X-Windows)
Is there a way I can get this behavior on Mac OS? alt + right-click-drag will resize the window, relative to where you've clicked within the window and the window's center alt + left-click-drag will move the window, regardless of where you've clicked within the window. There's a Windows port of this behavior as well: http://www.codeproject.com/KB/DLL/wm.aspx

Drag and Drop File into Application under run as administrator
Whenever I have an application running (Visual Studio 2008, Notepad, etc.) under "Run as Administrator", I cannot drag and drop files from Windows Explorer into the application.

How can I gently explain to non-techie friends they are the victim of a hoax?
We all have them. On Facebook, Twitter, even in email. That friend (or friends) that rebroadcast every hoax from abandoned puppies, abducted little girls or whichever political outrage email is currently en vogue. How can I educate my friend(s) who continue to do this and keep them as friends? If it only happened once or twice, I am sure I could just point out the appropriate page on Snopes.com or similar. I am specifically referring to serial offenders that actually think they are providing a service to the world.
How do I swap audio output of the left and right speakers?
I have two speakers stereo speakers but when I use the sound control panel applet to test my audio configuration I get sound in the right speaker when the user interface indicates the right speaker and vice versa. Is there a way to swap the audio output from left to right and right to left? UPDATE: The reason for this question is that I've recently rearranged my workspace and because of physical constraints the left speaker has to go on the right side and vice versa. I could of course solve this problem with a hardware solution but I'd rather use a software solution if one is available.

How can I check if an iptables rule already exists?
I need to add a rule to iptables to block connections to a tcp port from the Internet. Since my script may be called multiple times and there is not a script to delete the rule, I want to check if an iptables rule already exists before inserting it - otherwise there will be a lot of dup rules in the INPUT chain. How can I check if an iptables rule already exists?
SSH config - same host but different keys and usernames
I've set up two GitHub accounts, but I can't get ssh keys to work correctly. I've tried various configs. : Works for username1: at username2's repo: I've also tried with both and settings under same . The output is the same as with the last config. I think git automatically searches for Host "github.com" because the remote is such. It is said that Host can be anything you want (https://stackoverflow.com/a/3828682). Is there any way to change what Host from ssh config should specific repo use? It would be ideal if I could solve this just from ~/.ssh/config.
