Matrix is an up-and-coming chat protocol that provides a real alternative to proprietary solutions like Slack. Unlike Slack, Matrix is free, open source, and completely decentralized. With Matrix, you own your chat.

Most people have terrible passwords, and WiFi is no exception. Your WiFi password is your primary line of defense against unwanted access to your network. That access can result in a whole host of other nasty things because an attacker can monitor the traffic on your network and even gain direct access to your computers.

MAC address whitelisting sounds like a great way to prevent unauthorized access to your wireless network, but it doesn't work. The purpose of this guide is to demonstrate exactly how easy it is to spoof a whitelisted MAC address and gain access to a restricted network.

AMD's Ryzen CPUs were designed to be overclocked. They're excellent at it, and they benefit greatly from it. Most Ryzen CPUs can even overclock a few hundred MHz using a stock cooler. That's impressive no matter how you look at it.

The open source AMDGPU drivers don't have a fancy GUI interface that lets you overclock your card. Actually, they don't come with any kind of control center at all. That's alright, though, you can still overclock your card by modifying a couple of values in configuration files, a perfectly Linux solution if you think about it.

Modifying a bash script behavior via runtime options, just like we normally do with command line programs, can be very useful. The bash shell provides the getopts builtin command, a standard way to achieve this. How to use it is what we will learn in this tutorial.

In this tutorial we are going to learn how to restrict access to a Linux machine by interacting with two files: /etc/securetty, which let us specify from what console it's possible to login directly as root, and /etc/security/access.conf, in which we can set some rules to restrict access for specified users or groups from certain origins.

The following post is a little bit different from my other posts as it does not solve any of your Linux configuration problems. Apologies there! This post is an attempt to kill multiple birds with one stone, hence expose children to a command line, avoid web flash and ads driven multiplication practice tests online and most importantly gain some multiplication skills along the way.

Internet radio is a great way to listen to different radio stations from across your country or the world in real time. Unlike listening to your own music collection, it gives you the opportunity to discover new artists and genres that you might not have explored otherwise. Many Internet radio stations are browser-based, meaning they're easily accessible regardless of your operating system, but having yet another browser window open isn't all that convenient, and it eats into RAM. Plus, you're on Linux, why not have an awesome command line hack to tune into your favorite Internet radio station in seconds?

Bash isn't bad. It gets the job done just fine, but have you ever considered what it'd be like if Bash had some extra features to make it more convenient to work with? That's more-or-less what ZSH is. It includes all of the features that you'd expect from Bash, but it also has some really nice additions to make your life easier. Actually, you'll be amazed at how much easier they make working in the command line.

For over a year now, one game has been the white whale for Linux gamers. That game, of course, is Overwatch. For many, it's a game that should have been simple. Every other Blizzard game has had a Mac port and worked fine under Wine. Overwatch has been that one glaring exception.

UFW also known as Uncomplicated Firewall is an interface to iptables and is particularly well-suited for host-based firewalls. UFW provide an easy to use interface for beginner user who is unfamiliar with firewall concepts. It is most popular firewall tool originating from Ubuntu. It supports both IPv4 and IPv6.

No one wants to spend hours configuring and customizing their tiling window manager only for an ugly, poorly rendered notification window from GNOME to keep popping up and ruining the overall feel of their desktop.

Sure, there are backup utilities for Linux, but with a couple of scripts, you can keep your important files backed up regularly with little to no effort. A very simple Bash script will do the bulk of the work. For the rest, you'll take advantage of the cron system already on your computer.

If you've been using a window manager(tiling or otherwise), or you're thinking about it, you've probably looked into different options for menu bars. Most window managers either don't come with one, or they're packaged with something that's not all that useful. Polybar is an excellent answer.

One of the core activities of a system administrator is that of monitoring and interacting with the processes running on a machine. In this tutorial you will be introduced to the use of some fundamental tools that will help you accomplish that vital task.

AMD's Ryzen CPUs have been out for several months now, but AMD still hasn't released any specifications or code to get temperature monitoring support for CPU sensors in Linux. Thankfully, there are fairly accurate sensors on Ryzen motherboards, and they are accessible through Linux.

Audio formats are often easier to manage than video ones, but that doesn't mean that they don't come with their own headaches. For the most part, audio problems stem from DRM and losses in quality. While FFMPEG can't always help with DRM, it can help you to convert your files without losing quality.

Video formats can be a real pain. Some programs and devices only support a select few. Others take up loads of space on your hard drive. Even worse, the playback on poorly converted media is terrible.

FFMPEG puts the power in your hands and all from the command line. You can use FFMPEG to wrangle your video files into exactly the right file formats without sacrificing quality or dealing with clunky and incomplete GUI tools that have more dependencies than functionality.

Taskwarrior is a simple but powerful command line tool for managing tasks and objectives. Taskwarrior has been around for a while, and it's still in active development and going strong. As of today, Taskwarrior is probably the best command line task management utility available.
