Iptables is a firewall that plays an essential role in network security for most Linux systems. While many iptables tutorials will teach you how to create firewall rules to secure your server, this one will focus on a different aspect of firewall management: listing and deleting rules.

In this tutorial, we will cover how to do the following iptables tasks:

• List rules
• Clear Packet and Byte Counters
• Delete rules
• Flush chains (delete all rules in a chain)
• Flush all chains and tables, delete all chains, and accept all traffic

Dans ce cours, nous allons commencer par expliquer ce qu’est Git. Pour cela, nous allons définir ce qu’est un système de gestion de version et comprendre en quoi Git est différent des autres systèmes de gestion de version et pourquoi il est si populaire.

Nous allons ensuite découvrir les fonctionnalités principales de Git et apprendre à les utiliser. Nous apprendrons notamment à créer un nouveau dépôt Git avec la commande git init ou à cloner un dépôt existant avec git clone, à observer l’état d’un projet avec git status, à ajouter des fichiers à l’index avec git add, à valider des modifications avec git commit, etc.

Nous étudierons également le système de branches de Git qui est l’un des composants qui rendent ce système de version très puissant et flexible.

Finalement, nous découvrirons GitHub et apprendrons à gérer nos différents dépôts et à travailler sur des dépôts hébergés.

GraphQL is a powerful tool for querying data from remote servers and my preferred way of building APIs (Application Programming Interface). For some people, it might be difficult to learn as the tutorials are usually written using tools such as Apollo or Relay. These tools are great but often suited for more complicated projects. In certain scenarios, there might be better to choose a more lightweight approach and not increase bundle size with additional libraries. In these cases, you can work directly with the tools available in the browser. In this quick tutorial, we will use fetch, commonly available in your browser. Let’s first quickly revise what fetch is and how it is usually used with REST API, then we can move to simple GraphQL queries execution.
