In June, I wrote about Sproutling, a smart anklet designed for infants, in the first part of a series looking at how wearable technology is making more and more inroads into daily life. In this article, we explore Whistle, the “Fitbit for dogs."

In the United States alone, people will spend more than US $60 billion dollars on pets in 2015, according to the American Pet Products Association. Given that pet owners spend so much money, a dog wearable should come as no surprise. Skeptics may be quick to dismiss spending nearly $100 on such a wearable, but up until now, unless you're a dog whisperer, much of pet care has been guesswork, with issues mostly identified in hindsight.

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.
