BitTorrent Sync is what seems to be a great encrypted serverless Dropbox alternative. You can read more about the technical background here. It provides clients on OSX, Linux, Windows, Android, iOS, ARM and others. The client for ARM can easily be run on the Raspberry Pi. Just download the binary and copy it to your pi. Start it by executing “./btsync”. You can now access a web interface at http://[raspberry IP]:8888/gui. This interface allows you to create new “Shares” or connect a local folder to and existing one.
Reflection for Mac allows to mirror an iPad 2 or iPhone 4s screen on a Mac for presentations etc. By default the image gets scaled to 1280x720px but it’s also possible to use the native device resolution. A detailed test of the application you can find here (German).
It’s an augmented-reality, OCR-capable translation app, but that’s a poor description. A better one would be “magic.” World Lens looks at any printed text through the iPhones camera, reads it, translates between Spanish and English. That’s pretty impressive already — it does it in real time — but it also matches the color, font and perspective of the text, and remaps it onto the image. It’s as if the world itself has been translated.
