If you use an Android phone with location services turned on Google is tracking your location. Want to see where you have been? Just go to https://maps.google.com/locationhistory/b/0 and log in with the same account that you use on your phone. The map will show you where you have been for the last day, week, or even month. Now, this works best if you travel long distances or in areas with a lot of cellular phone towers, but should show up some general locations even if your travels are minimal. Is this amazing, scary, or some of both?

If you are ever looking for a good power source for 12 V or 5 V devices, look no further than an old PC power supply. A few simple modifications are all it takes to get one of these to provide clean 12 V and 5 V power. Most modern PC power supplies do not have real "on-off" switches and require the motherboard to tell the power supply to turn on. You can simulate this by connecting the on-off wire (usually green) to the common (usually black). If your power supply is a standard ATX supply, refer to the pinout to verify the location of these pins. You can then use the 5 V (usually red) and 12 V (usually yellow) power pins to your device. These supplies can also supply -12 V & 3.3 V (usually orange). These are also useful for some electronic devices. If you do attempt to convert your old computer power supply be very careful as there are hazardous voltages inside.
Has Windows reported that your hard drive is failing? If you have, heed its warning and backup your files immediately. I am currently trying to recover files from such a device. It's difficult, to say the least. One of the most difficult aspects of a failing hard drive is recovering the files from the user folders. Copy these files to your backup choice as quickly as possible. These files are password protected so moving the drive to a new machine and attempting to copy them is not as easy as copy and paste.
If you ever find yourself trying to copy files from an old hard drive that is failing, or otherwise has files tucked away in a user account folder, here are a few tricks you can use to unlock the files for access, after all, it's your data anyway.
1] Install the "Take Ownership" Registry hack and use as described.
2] Use the security tab to give the administrator access.
3] Copy files in as small of groups as possible to reduce load on the failing HD.
