The talk focuses on 1D and 2D barcode applications with interference possibilities for the ordinary citizen. Ever wondered what is in these ... all » blocks of squares on postal packages, letters and tickets? Playing with them might have interesting effects, reaching from good old fun to theft and severe impact.
Barcodes have been around for ages, but most of the time were used as simple tags with a number. The rise of 2D barcodes started to put them into customer hands as authentication, authorization, payment method and other arbitrary data transport. The implicit trust in them is enormous. The talk gives a very quick intro into barcodes and then proceeds to review the contents of selected samples, including their usage in the real world. This is going to be fun, tool release included.

Chinese lunar orbiter to begin observations
Chinese lunar orbiter to begin observations - New Scientist Space
China's lunar orbiter is set to begin switching on its science instruments. The spacecraft should help determine the thickness of the lunar soil and shed new light on the Moon's internal composition, which could help in understanding its origins.
......
Like the other missions, Chang'e 1 has spectrometers to map the chemical composition of the Moon's surface, a laser altimeter to map the Moon's topography, and a camera to photograph the surface.
However it does have one unique instrument – a radiometer that operates at microwave frequencies. The microwave radiometer will measure heat radiation coming from the Moon. This will allow it to map the depth of the lunar soil across the Moon's surface because the layer's thickness affects the flow of heat.
