What happens when two computers on the same network have the same MAC address?

What do you do about wrist pain?
I use the computer for many more hours per day than any human should, and consequentially I have wrist pain. It hurts to hold the mouse in my hand.

How do I make Windows 7 boot further than a blank screen with only a mouse cursor?
My Windows 7 machine was powered down without logging out first. Now, when booting the PC Windows 7 does not completely start.

Why does Windows 7 ask for additional drivers when installing from a USB 3.0 drive?
I just bought a new config ( ASUS p8z68-v lx, i5-2500k + ram and new graphic card ). Coming back and installing it in my old computer, I just saw that my DVD player was on IDE (yup…).

How to type zero-width space character (U+200B) on a laptop keyboard?
There is a very similar question to this one already (How can I type U+200B character?) but all the answers are about how to type this character on a PC keyboard with a num pad which is not my case.

How does Safari's Reader work and when does it show up?
Safari's Reader feature is a cool little app that displays a web page as a newspaper article --- without all the distracting sidebars, comments, and ads.

Switch between columns' active tabs in Sublime Text 2
