Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a Virtual Machine (VM) on your laptop for users looking to try out Kubernetes or develop with it day-to-day.

This isn’t so much a docker tip, as it is a jq tip. If you haven’t heard of jq, it is a great tool for parsing JSON from the command line. This also makes it a great tool to see what is happening in a container instead of having to use the –format specifier which I can never remember how to use exactly

I’m going to go with the good ol’ “It depends.” However, I first want to commend you for actually owning your own cable modem instead of coughing up $14 or so each month for Comcast to rent you one of their *meh* modem/router combinations. There’s no reason you should be paying a fee to rent that which you can purchase yourself. Of course, this also means that you’ll have to buy a new cable modem if, or when, your internet plan exceeds your modem’s capabilities.

The good news? Measuring that ROI is arguably easier than ever for small businesses. By stressing efficiency and using the right tools, uncovering and tracking new leads, traffic and revenue don’t have to feel like a guessing game. Making it all happen starts with a process of defining what positive results look like and identifying the most efficient paths to achieving those results.

The 2015 edition of the ECMAScript specification (ES6) added template literals to the JavaScript language. Template literals are a new form of making strings in JavaScript that add a lot of powerful new capabilities, such as creating multi-line strings more easily and using placeholders to embed expressions in a string. In addition, an advanced feature called tagged template literals allows you to perform operations on the expressions within a string. All of these capabilities increase your options for string manipulation as a developer, letting you generate dynamic strings that could be used for URLs or functions that customize HTML elements.

Flask is a framework for building web applications using the Python language, and SQLite is a database engine that can be used with Python to store application data. In this tutorial, you will use Flask with SQLite to create a to-do application where users can create lists of to-do items. You will learn how to use SQLite with Flask and how one-to-many database relationships work.

In React, state refers to a structure that keeps track of how data changes over time in your application. Managing state is a crucial skill in React because it allows you to make interactive components and dynamic web applications. State is used for everything from tracking form inputs to capturing dynamic data from an API. In this tutorial, you’ll run through an example of managing state on class-based components.

TLS, or “transport layer security” — and its predecessor SSL — are protocols used to wrap normal traffic in a protected, encrypted wrapper. Using this technology, servers can safely send information to their clients without their messages being intercepted or read by an outside party. In this guide, we will show you how to create and use a self-signed SSL certificate with the Apache web server on a CentOS 8 machine.

When managing a server, you’ll sometimes want to allow users to execute commands as “root,” the administrator-level user. The sudo command provides system administrators with a way to grant administrator privileges — ordinarily only available to the root user — to normal users. In this tutorial, you’ll learn how to create a new user with sudo access on Ubuntu 20.04 without having to modify your server’s /etc/sudoers file.
