Practical AI for Healthcare Professionals
Artificial Intelligence (AI) is a buzzword in the healthcare sphere today. However, notions of what AI actually is and how it works are often not discussed. Furthermore, information on AI implementation is often tailored towards seasoned programmers rather than the healthcare professional/beginner coder. This book gives an introduction to practical AI in the medical sphere, focusing on real-life clinical problems, how to solve them with actual code, and how to evaluate the efficacy of those solutions. You'll start by learning how to diagnose problems as ones that can and cannot be solved with AI. You'll then learn the basics of computer science algorithms, neural networks, and when each should be applied. Then you'll tackle the essential parts of basic Python programming relevant to data processing and making AI programs. The Tensorflow/Keras library along with Numpy and Scikit-Learn are covered as well. Once you've mastered those basic computer science and programming concepts, you ...

Bash Guide
This guide aims to aid people interested in learning to work with BASH. It aspires to teach good practice techniques for using BASH, and writing simple scripts. This guide is targeted at beginning users. It assumes no advanced knowledge - just the ability to login to a Unix-like system and open a command-line (terminal) interface. It will help if you know how to use a text editor; we will not be covering editors, nor do we endorse any particular editor choice. Familiarity with the fundamental Unix tool set, or with other programming languages or programming concepts, is not required, but those who have such knowledge may understand some of the examples more quickly. ...

Taking Kubernetes from Test to Production
With Kubernetes came many new concepts, particularly around networking and traffic management. Alongside these new concepts were entirely new classes of tools, designed for ephemeral, containerized, and distributed application deployments. In particular, Ingress controllers and service meshes did not exist prior to the Kubernetes era. Nor were Layer 4 and Layer 7 protocols and traffic typically managed from the same control plane. At a granular level, Kubernetes introduces new complexities around security and management. Simple tasks like load balancing are very different in a realm where infrastructure is 100% ephemeral and often moving constantly - both in terms of setting up new instances with fresh IP addresses and geographically moving around the globe. These new traffic management concepts and tools have the power to vastly improve developer experience and accelerate app development and delivery cycles through greater resilience, higher performance, and better security. But wh ...
