Reverse Image Searching

In this form of searching, you upload an image, sketch or 3D object, and you get results based on where the image comes from, where else the image is placed and if (and where) there are similar images on the net.

Raise the speed limit!

As an example, Peterson pointed to changes made along a section of Interstate 496 outside of Lansing, which accounted for 40 percent of reported incidents of aggressive driving in that area. When the speed limit was raised from 55 mph to 70 mph, incidents of aggressive driving dropped to zero.

“The low speed limit frustrated many drivers, so they drove over the speed limit. This caused problems for other drivers who were driving at the limit. The speed differential caused the tailgating, passing, and speeding that were reported as ‘aggressive’ driving,” Peterson said.

His data also showed accident rates in that area also fell when the speed limit was raised.

Surprisingly, the higher speed limit also improved traffic flow, nearly eliminating all symptoms of rush hour congestion along that stretch.

UK: CCTV snooping becomes a game

Yup – someone had to think of a way to turn those CCTV camera’s into something that everyone had access to! In an internet game, people are encouraged to use the CCTV network to spy on people in the street. Whoever catches the most “criminals” (say litterers or jaywalkers) gets GBP 1000,- every month! Have fun participating in the spy state!

Internet game that awards points for people spotting crimes on CCTV cameras is branded ‘snoopers paradise’ | Mail Online.

Pirate Bay continues

The whole Pirate Bay saga continues: after strange court orders, dodgy sales, bans on Google, etc, etc, here is the  latest:

Pirate Bay’s Peter Sunde has gone to the Dutch police and has charged the Brein organisiation with fabrication of evidence and fraud.

Pirate Bay doet aangifte tegen Brein en Kuik – update 2 | Webwereld.

Brein has been trying to get the Pirate Bay down globally – due to Brein suboepna’ing the 3 mere conduits for the IP range they use:

That block has been circumvented by a Dutch guy working for a German host

Default Contact Country

Oh the idiocy of it all!
In the Apple iPhone 3.0.1, you can set the default contact country by going to settings -> general -> International and then changing the region format. This means that even if you won’t see the country name in the contact, when you look it up in Google Maps for the location, it’ll add that country name to the address bar. (NB Not fixed in 3.1)

Outlook 2007 suffers from the same lunacy – In Control Panel -> Regional and Language Options -> Formats Tab – this is where outlook gets the country from when adding new contacts. No, it doesn’t use the country in the you would have thought this is obvious ‘Location’ tab.

Not a big deal? So what if you’re an expat? Say you’re an Englishman living in Malaysia or Belgium or Holland. Yup, all the addresses you add will be in those countries, but you’ll manually have to set the country every time.

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.

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.

Skynergy Memoriser

Memoriser is a utility to help you remember phone numbers, account numbers, passwords, birthdays and anything that is important for you to remember but you haven’t actually taken the time or effort to do so.

Define a question with an answer and let Memoriser quiz you until you remember this question’s answer without even thinking but just knowing the answer! Memoriser uses a scoring system to make sure that you focus more on questions answered incorrectly. Answering a question correctly increments the score. Correct answers will be asked less frequently than wrong answers.

Augmented Google Earth Gets Real-Time People, Cars, Clouds | Popular Science

Researchers from Georgia Tech have devised methods to take real-time, real-world information and layer it onto Google Earth

They use live video feeds (sometimes from many angles) to find the position and motion of various objects, which they then combine with behavioral simulations to produce real-time animations for Google Earth or Microsoft Virtual Earth.

They use motion capture data to help their animated humans move realistically, and were able to extrapolate cars’ motion throughout an entire stretch of road from just a few spotty camera angles

Now where would you happen to have loads of CCTVs you could use to spy on everybody realtime? I wonder…

UK wants your DNA

Lovely. If you’re an asylum seeker, the UK border patrols will want to take you DNA through your hair and nails to determine your nationality. Not only is this an insane breach of your person, there is also no scientific methodology being given out to show how exactly anything will be accomplished by the investigating company (whoever that is).
