If you’re reading this post then you probably want to use an MP3 file as the sound played by your Android phone when it wakes you up in the morning.
To do that you just need to create a folder named alarms (lowercase) and put the MP3 file under it.

IMPORTANT NOTE: you might need to reboot your phone in order to see the new alarm tone

P.S.: I’ve got a Samsung Galaxy i7500 and that worked for me. However, it should work for every Android phone.

I don’t know about you, but I love the Firefox’s undo-close-tab feature (Ctrl+Shift+T). If you use Eclipse you might be glad to know you can undo the close-tab action in Eclipse as well. You can do that both using your mouse by clicking on the yellow left arrow you can see in the Eclipse toolbar and through the keybord using the Alt+Left Arrow key combination.

I hope this helps.
