I’ve always thought that 3-D gadgets were like Twitter—impressive and charming, but rarely worth the fuss. In film, Hollywood’s garish three-dimensional visuals fail to disguise its typically two-dimensional characters and one-dimensional plots, and I can’t be the only person who balks at the idea of donning clunky glasses to watch TV at home. So I approached Fujifilm’s new FinePix Real 3D W3 digital camera full of doubt.

From WinZips to Cat GIFs, Jacob Ziv’s Algorithms Have Powered Decades of Compression

Lossless data compression seems a bit like a magic trick. Its cousin, lossy compression, is easier to comprehend. Lossy algorithms are used to get music into the popular MP3 format and turn a digital image into a standard JPEG file. They do this by selectively removing bits, taking what scientists know about the way we see and hear to determine which bits we'd least miss. But no one can make the case that the resulting file is a perfect replica of the original.

Not so with lossless data compression. Bits do disappear, making the data file dramatically smaller and thus easier to store and transmit. The important difference is that the bits reappear on command. It's as if the bits are rabbits in a magician's act, disappearing and then reappearing from inside a hat at the wave of a wand.
