TensorFlow is a free, open-source machine learning framework that’s geared towards deep learning. Optimization algorithms are at the heart of artificial neural networks. We can therefore let TensorFlow solve numerical optimization problems.
Over the years I have worked with some good product managers, heard of a few great ones, and endured others who were less than stellar. From these observations and my own experience, I have distilled a set of principles for product managers, a collection of dos and don’ts.
Scio is Spotify’s open-source Scala API for Apache Beam and Google Cloud Dataflow. It’s used by data engineers at Spotify to process many petabytes of data each day. Let’s look at the different joins it supports and how and when to use each.
While you can take great stereoscopic pictures with a smartphone using sequential shots, as I described in the first and second parts of this three-part series on smartphone stereo photography, sometimes you want to capture a three-dimensional scene in motion. Even that’s possible but you do need additional gear, for instance the Kúla Bebe.
There are a few subtle changes between Scala 2.11 and 2.12/2.13 when it comes to conversions between Java and Scala types that you may not be aware of: nullable boxed primitives, such as numbers.
Algebird, Cats, and Scalaz are Scala libraries that provide, among other things, type classes that are based on algebraic constructs, such as groups, rings, and monoids. Contrary to what I had initially believed, perhaps naively, these libraries do not perform compile- (or run-)time checks on the laws governing these algebraic structures, which means it’s possible to create a class that is an instance of such a type class, but it violates the laws of that type class.
