RoomScan is an app for iOS which draws floor plans in minutes – touching your device to a wall is the only input required. Using the iPhone’s internal sensors, RoomScan recognises a sequence of flat vertical surfaces, measuring the distance in between and creating impressively accurate plans. When you come to a door, you just tap the phone to the door frame and continue. Claiming that measurements are accurate to the nearest 10cm (or 6 inches), this app – the basic features of which are available for free - is not only great fun to play with, but also considerably useful in every day situations.
Hmmm, might be an easy (and relatively cheap) way to play around with Tor and learn a bit more about this anonymizing service. -- Douglas Adafruit’s Onion Pi is a Tor proxy that makes your web traffic anonymous, allowing you to use the internet free of snoopers and any kind of surveillance. Follow Adafruit’s tutorial on setting up Onion Pi and you’re on your way to a peaceful anonymous browsing experience. Tor is an onion routing service – every internet packet goes through 3 layers of relays before going to your destination. This makes it much harder for the server you are accessing (or anyone snooping on your Internet use) to figure out who you are and where you are coming from.
