'... In layman's terms, an algorithm is a step-by-step procedure for calculating the answer to a problem from a given set of inputs, Ziewitz says. Algorithms at the heart of Google's search engines, for example, take a search term, sort through web pages, calculate their relevance to the term and pick the top 10 pages.

Algorithms can also be simple. To structure their walk, Ziewitz and a friend wrote this one on a sheet of paper: "At any junction, take the least familiar road. Take turns assessing familiarity. If all roads are equally familiar, go straight."

They could have created any number of instructions, such as "take every third left." But that would not have solved the problem they decided to tackle – a crucial requirement for algorithmic processing. "The key here is that you have to define the problem before your code can make any sense," Ziewitz said.

Why was Python chosen by Google to make TensorFlow? "The most important thing to realize about TensorFlow is that, for the most part, the core is not written in Python: It's written in a combination of highly-optimized C++ and CUDA (Nvidia's language for programming GPUs). Much of that happens, in turn, by using Eigen (a high-performance C++ and CUDA numerical library) and NVidia's cuDNN (a very optimized DNN library for NVidia GPUs, for functions such as convolutions)."

"The Florida State University-headquartered National High Magnetic Field Laboratory has shattered another world record with the testing of a 32-tesla magnet—33 percent stronger than what had previously been the world's strongest superconducting magnet used for research and more than 3,000 times stronger than a small refrigerator magnet."

... The big VR story this year isn't another headset from Oculus or HTC -- it's Microsoft's entry into the space with Windows 10 Mixed Reality devices. They promise to be cheaper and easier to use than the Rift or Vive, thanks to a bit of help from HoloLens' 3D tracking technology. Acer's was among the first we saw in action, and it was a promising example of what an inexpensive VR headset could look like. Samsung, meanwhile, was late to the party with HMD Odyssey, but it also gave us a glimpse at high-end Mixed Reality headsets. Now that we've spent some time with both (along with HP's headset earlier this week), it's time to decide which handles Mixed Reality best. (Spoiler: It isn't Acer.) ...
