If you use the program youtube-dl, you may have noticed that from time to time things stop working. Usually it’s because something changes on a site and youtube-dl needs to be patched to deal with it. But what sometimes happens is that someone will submit a patch and then the youtube-dl developers will ignore that patch for many months before they finally get around to merging it into the program. The speed at which the youtube-dl developers fix issues with sites can seem glacial at times.
What’s frustrating is that if you browse through the issues section of the youtube-dl support area using an appropriate search term, you may find the fix for your problem, and maybe it’s just been sitting there for quite some time. But, since youtube-dl is distributed as a compiled binary you may think you have no way to apply it. But that’s not really true – at its core, the entire program is simply a multitude of Python scripts, and it can be run without first being compiled. And if you use it that way, then you can apply patches as needed to any of the python modules, whether they are patches you have written or patches that you have found in the issues area, or elsewhere on the Internet.
So here is how you can install and use youtube-dl using actual source code.
ffmpeg is a CLI (command line based) utility for processing media files. It is a framework with a multitude of features and, because of it’s open source license, it is the base for many widespread apps such as VLC, YouTube, iTunes and many more. A number of Linux video editors use ffmpeg underneath the GUI.
What I love even more about ffmpeg is that it can be used on it’s own to accomplish many processing tasks in a very simple manner (with one or two commands). However, it’s a very powerful program that can be used in more complex ways and even replace an editing workflow.
In this ffmpeg tutorial, I’ll show you how to install ffmpeg and I’ll be covering it’s different uses. I’ll even get into some more complex features.

1. Firefox Privacy – The Complete How-To Guide
Mozilla Firefox is arguably the best browser available that combines strong privacy protection features, good security, active development, and regular updates. The newest version of Firefox is fast, light-weight, and packed full of great settings to protect your privacy.
It is for this reason that I consider Firefox to be the best all-around browser for privacy and security. It remains a solid alternative to some of the other options, such as Google Chrome, Microsoft Edge, and Safari.
Another great aspect of Firefox is that it is highly customizable, which is the point of this guide. Below we will go over how you can customize Firefox to give you the security and privacy you desire, while still working well for day-to-day browsing.
