Revisiting the Antikythera Mechanism Emulator
Over the past few weeks I updated the
Antikythera mechanism emulator
I built in 2007.

background and a series of overlaid images with the stark colors of the gears.

Fixing the Orientation of JPEG Photographs
I used to fix the orientation of my photographs through an application
that would transpose the compressed JPEG blocks.
This had the advantage of avoiding the image degradation of a
decompression and a subsequent compression.
