This Week I Learned -

* You can think of microservices as “SOA done right,” with principles and patterns like autonomous services, Bounded-Context pattern and event-driven all having their roots in SOA and DDD. As the name implies, microservices architecture is an approach to build a server application as a set of small services, each service running in its own process and communicating with each other via protocols such as HTTP and WebSockets. Over the long term, microservices enable superior maintainability in large, complex and highly scalable systems by designing applications based on many independently deployable services that allow for granular release planning. Azure Service Fabric is a new platform built from the ground up and especially designed for hyperscale and microservices-based systems - MSDN Mag

Two professors of National Tsinghua University in Taiwan, have used machine learning to create a system where bots watch a video, determine its highlights, create a relevant title for easy searching, and recommend who might want to be tagged to watch it. Their work was inspired by Microsoft Research’s COCO (Common Objects in Context). COCO is a new image recognition, segmentation, and captioning dataset that recognizes more than 300,000 images, in context, and because videos are essentially a succession of images, this dataset could help with video title generation - Microsoft Research Blog

* Cognizant recently announced that it has cloud-enabled the IT infrastructure at ACCO Brands Corporation (NYSE: ACCO), one of the world’s largest suppliers of branded school, office and consumer products and print finishing solutions, for improved business agility, performance and reduced costs. By migrating mission-critical workloads in enterprise SAP systems from an on-premise data center to the Microsoft Azure cloud platform and implementing a pay-per-use Infrastructure-as-a-Service (IaaS) model, ACCO Brands has improved the flexibility, availability and scalability of its IT environment, reducing risk and enabling it to quickly respond to changing business requirementsET

* Videoconferencing equipment is often left vulnerable to hackers. Most of these new systems were designed with visual and audio clarity — not security — in mind. The most popular units, sold by Polycom and Cisco, can cost as much as $25,000 and feature encryption, high-definition video capture, and audio that can pick up the sound of a door opening 300 feet away. But administrators are setting them up outside the firewall and are configuring them with a false sense of security that hackers can use against them. After a security breach at the United States Chamber of Commerce last year, the Chamber discovered that its office printer, and even a thermostat in a Chamber-owned apartment, had been communicating with an Internet address in ChinaNY Times

* The messaging app Snapchat allows motorists to post photos that record the speed of the vehicle. The navigation app Waze rewards drivers with points when they report traffic jams and accidents. Even the game Pokémon Go has drivers searching for virtual creatures on the nation’s highways. Most new vehicles sold today have software that connects to a smartphone and allows drivers to place phone calls, dictate texts and use apps hands-free. Ford Motor has its Sync system, for example. Others, including Honda, Hyundai and Mercedes-Benz, offer their own interfaces as well as Apple’s CarPlay and Google’s Android Auto. After steady declines over the last four decades, highway fatalities last year recorded the largest annual percentage increase in 50 years. Insurance companies, which closely track auto accidents, are convinced that the increasing use of electronic devices while driving is the biggest cause of the rise in road fatalities - NY Times
