| Dear Reader, Reactive must be one of the most overloaded terms of the last year in computer science. In the last week on the site we've run a number of pieces trying to separate hype from reality. Our most recent eMag covers reactive programming in Java with examples using rxJava, Pivotal's Reactor, and Akka. Meanwhile, Jonas Boner, CTO of LightBend, co-author of the reactive manifesto and creator Akka, spoke to Wesley Reisz on using Akka when developing distributed systems. He talks about the Actor Model, reactive systems, and how every Microservice needs to be viewed as a system to be successful. A second big theme for the week was IoT. WSO2 has announced a new, fully-open-source WSO2 Internet of Things Server edition. As Kevin Farnham points out "... while WSO2 has been involved in the IoT marketplace for some time, the announcement that their IoT Server is now 100% open source is significant." In addition, the recently released Developer Preview 2 (DP2) for Android Things makes it easier to use TensorFlow for machine learning and computer vision on IoT devices. We also took a look at a complete DevOps lifecycle for an Internet of Things (IoT) application using Microsoft frameworks and components. The concepts can be generalized to other IoT platforms with some changes. Elsewhere on the site, in the first of three articles Erik Hogan describes how PayPal went from a monolithic, siloed architecture to a much more loosely coupled set of over 150 services with well designed, modern APIs over the course of three years. Apple has proposed a new GPU API for the browser, called WebGPU. Twitter recently switched all of their mobile web front-end users to a modern, JavaScript-based web stack. In doing so, they demonstrated how advancements in mobile web technologies rival the performance of native-based apps. The new browser-based UI is built atop React with Node.js and Express handling the server side. The fashion industry is one sector making considerable use of deep learning. We took a look this week at some of what Gilt has been doing with regards to product recommendations and clothing properties categorization. Related, in a previous edition of the InfoQ podcast we talked to Randy Shoup, vice president of engineering at Stitch Fix, about the firm's use of ML. |
