Download Tech Beacon
A Mindtree Publication I Volume 4 I 2018 ABOUT Technology is core to Mindtree. It is extremely important in building capability and capacity for us to keep a sharp focus on emerging technologies. We also make it a point to understand the application of these technologies in the context of our customers. In this effort, we constantly explore and experiment with emerging technologies and gauge their maturity levels for consumption by enterprises. We do this by comparing and contrasting them with similar tools already in use. Tech Beacon is an initiative to compile outcomes of our experimentation and technology adoption guidance for enterprises. We group technologies under three categories: Invest, Experiment and Watch. We explain these categories in detail in this report. Direction Tech Beacon provides direction to enterprises on various technologies by categorizing them as Invest, Experiment or Watch technologies. Invest These technologies have a high potential for generating business value in the near future. Mindtree intends to build capability internally or identify a partner who can help our project teams learn to bootstrap these technologies. We arrive at these technologies by observing customer demands, industry trends, opportunities and open source community support. Most of these technologies were either implemented in production-grade applications for customers, or in internal reference implementations. Experiment These technologies have not yet seen mainstream adoption but show huge promise for the near future. We arrive at these technologies by listening to our customers’ interests, following industry buzz, and noting indications of increased activity in various forums and analyst reports. We need to experiment and build capability in these technologies to have an early adopter edge. -

HACKING WITH SWIFT COMPLETE TUTORIAL COURSE Learn to make web E PL apps with real-worldAM S Swift projects EE FR Paul Hudson Chapter 1 Million Hairs www.hackingwithswift.com 2 Setting up The first project of any book is always difficult, because there’s a steep difficulty ramp as you learn all the basics required just to make something simple. I’ve tried to keep it as simple as possible while still teaching useful skills, so in this initial project you’re going to create a website for the Million Hairs veterinary clinic. Along the way you’re going to learn how to create and configure a project using the Swift package manager, how to route users to different parts of your code depending on the URL they enter, how to log information, and how to separate your code from your presentation – i.e., how to keep Swift separate from HTML. Now, it’s possible you think I’m already patronizing you: surely you already know how to create a new Swift project? You have to remember that server-side Swift is designed to work across platforms, which means that it relies on Xcode far less. In fact, by default Xcode isn’t involved at all: you create your project using the Swift package manager, which comes bundled with the open-source Swift distribution. If you’re using macOS with Xcode installed, you already have access to the Swift package manager. If you’re using Docker with IBM’s Kitura container, then that pre-installs the Swift distribution and gets the package manager that way.
