Comment A Fan of Security (Score 5, Funny) 258
I was deployed to Iraq, and we had to download a very large file. Unfortunately, we were working on laptops that would lock the screen after 15 minutes, and then the laptop would loose connection. Considering that the file was going to take 8-10 hours to download, this was not acceptable.
I found an oscillating pedestal fan, and I duct-taped a yardstick between the fan and a mouse connected to the laptop. Since the laptop would not lock due to the mouse movement, all I had to do is to place a few books to limit the moment area; the next morning the file was downloaded. I realize this might not be the hack for which you were looking, but since it involved duct-tape I thought it would count.
