If you’ve ever uploaded a picture to Facebook or tried to attach a file to an email using the “add attachments” button, you know it can be a pain using the tiny pop-up file uploader window to navigate through your folder structure to the file you want. If you’re on a Mac (and some versions of Windows) you can make this process much quicker by dragging the file to the upload window.
The next time you want to upload a file, keep the folder it is in next to your browser window (or on the desktop). When the upload window appears, simply drag the file over top of it and drop. The upload window will automagically snap to the correct folder and highlight the file. All you have to do is click the upload button.

It may not give you invisibility or the ability to walk through walls, but Windows 7 has it’s own GodMode.
Create a new folder anywhere on your machine. Then, change the name to read:
GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}
Once you hit enter, you will discover a world of Windows 7 hackery and tweaks. Open the new file that is created and you should see a screen that looks like the one below.
Be warned, with great power comes great responsibility, of which I share none with you.

Use this at your own risk.
Up, down, left, right, A, B, start!
