Wireless network modded to see through walls

the way radio signals vary in a wireless network can reveal the movement of people behind closed doors. Joey Wilson and Neal Patwari have developed a technique called variance-based radio tomographic imaging which processes the signals to reveal signs of movement. They’ve even tested the idea with a 34-node wireless network using the IEEE 802.15.4 wireless protocol

Carrier Command: Gaea Mission

Carrier Command: Gaea Mission is a rebuild of the excellent classic Carrier Command, which allows you  to command from the deck of a futuristic aircraft carrier. Your job is to colonise islands as manufacturing, defence or mining and build up a logistics base for your carrier. You can launch ground vechiles (Walrusses) and UAVs (MANTA’s) to go about scouting your way, building colonies and attacking the enemy carrier which is trying to block your way. At the time, the original was an awesomely fluid 3D engine using filled vector graphics. The new version adds troops and looks awesome, as well as true to the original. You can download the original here, I’m very much looking forward to it.

The only game that has come anywhere near to this was the very very buggy Battlecruiser series by Derek Smart.

Dutch passports require unsecure fingerprints

We should all know by now that the fingerprint biometric is a bad one: not only can you duplicate it fairly easily using just gummy bears, or increase the risk of having your finger cut off for you, they also give too many false negatives; some people will never be able to use fingerprint scanners.

The problem here is that because they have to automate the fingerprinting process, you get a lower level of accuracy in the scans. No two prints by the same finger are ever exactly the same. This is corrected for by error correction codes, which adds information to the prints to allow the computer to correct for these disparities. If you can get to these codes, you can find out information about the original fingerprint and the amount of data loss that is expected. So searching through the error correction code database allows you to find a fingerprint that is similar to yours and has a large correction. This means you can become this other person fairly easily.
