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 est un framework permettant de créer des applications Web à l'aide du langage Python, et SQLite est un moteur de base de données qui peut être utilisé avec Python pour stocker des données d'application. Dans ce didacticiel, vous utiliserez Flask avec SQLite pour créer une application de tâches dans laquelle les utilisateurs peuvent créer des listes d'éléments de tâches. Vous apprendrez à utiliser SQLite avec Flask et comment fonctionnent les relations de base de données un à plusieurs.

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.

By default, Jenkins comes with its own built-in Winstone web server listening on port 8080, which is convenient for getting started. It’s also a good idea, however, to secure Jenkins with SSL to protect passwords and sensitive data transmitted through the web interface. In this tutorial, you will configure Nginx as a reverse proxy to direct client requests to Jenkins.

Slack is a communication platform designed for workplace productivity. It includes features such as direct messaging, public and private channels, voice and video calls, and bot integrations. A Slackbot is an automated program that can perform a variety of functions in Slack, from sending messages to triggering tasks to alerting on certain events.
