Lockergnome tipped people off to this page which talks (among other things) about adding "Copy To" to the context menu. I considered adding this tweak to Tweak UI but ultimately decided against. Here's why: The "Copy to Folder" and "Move to Folder" options weren't designed to be on the context menu. They were only meant to be placed in ...

Jeff Davis tipped me off to this Ikea walk-through. Frustratingly, the walkthrough doesn't include any cheat codes. Even though Ikea was founded by a Swede, its company colors match the Swedish national colors, all its product names are Swedish, and it is clearly associated with Sweden in the minds of everyone, it is in fact headquartered in...

Your DllMain function runs inside the loader lock, one of the few times the OS lets you run code while one of its internal locks is held. This means that you must be extra careful not to violate a lock hierarchy in your DllMain; otherwise, you are asking for a deadlock. (You do have a lock hierarchy in your DLL, right?) The loader lock ...

I'm pulling for the Mars rovers as much as the next geek, but you still have to scratch your head at the following statement: Charles Elachi, the JPL director, said: "I am completely confident, without any hesitation, that I think we will get that rover back to full operation." So he's absolutely sure that he "thinks" something...
