The previous article in this series described the special features that make functional programming attractive. This article applies those concepts to programming today. Some Important Influences of Functional Programming Although functional languages have always been held at arm’s length by … Read more

While we have talked a lot about application deployment, we still need to cover how to keep these applications up and running. The DevOps Tools Engineer exam covers Prometheus Monitoring for this task. Modern IT operations have evolved from merely … Read more

I hope this series has given a sense of how the data mosaic works: how small and innocent-looking details about you can be combined to uncover sensitive information. Data collection will only improve over time. Theoretically, you can be identified … Read more

Objective 703.2 of the DevOps Tools Engineer 2.0 exam covers Basic Kubernetes Operations. It represents a significant portion of the exam and requires a solid understanding of how to deploy and manage applications in Kubernetes. Candidates should be able to: … Read more

This article is part of a continuing series about data collection today. I wanted in the previous articles to demonstrate how pervasive information intrusions are among all kinds of institutions, before turning in this article to governments, where most people … Read more

Functional programming is one of the fundamental divisions among programming languages, and can be traced back very early in programming history: notably to LISP and ML. This series interviews leading proponents of some current functional languages to look at their … Read more

In previous discussions about DevOps tools, we explored container virtualization and how containers transformed the way applications are packaged and deployed. One of the major advantages of containers is their extremely fast startup time combined with minimal resource overhead compared … Read more
