Wall of the Fallen.

This is your semi-regularly-scheduled reminder to do your backups!

A photograph of the side of a metal filing cabinet, taken at an oblique angle. Spread across the surface are 17 pairs of rare-earth magnets (probably neodymium-iron-boron, the most common kind). These are used in computer hard disk drives as part of the head mechanism; so called "voice coil" drives (which is all modern drives) position the head extremely finely by inducing a magnetic field in a coil attached to the pivoting arm that holds the read/write heads. The arm and coil are placed between the surfaces of the two magnets; by changing the field in the coil, the arm can be made to push against the fixed magnetic field of the magnets, resulting in very precise control of the head position. These magnets were salvaged from disks as they died in my servers, so 17 dead disks are represented here. Do your backups!
