Debian's current stable package repository may not always contain an up to date software to be in line with our expectations. There is a very good reason for this, such as a stable system as a trade-off for running bleeding edge software. The current PHP developer's claims put PHP 7 in front of PHP 5.6 in terms of speed, where PHP 7 is supposed to be as twice as fast as its predecessor.

Netflix and Linux have a somewhat troubled past. For years, Netflix actively blocked Linux users. More recently, support for Google Chrome was added. Firefox users, however, have been out of luck until just recently. As of Firefox 49, the option of using Google's DRM from the Chrome browser to play DRM content has been made optionally available to Firefox users. This has made it possible to watch Netflix, and potentially other DRM streaming services, using Firefox and without installing Google Chrome. What's better, the DRM can be turned off when you're done watching.

Python is a big deal. It is one of the fastest growing and most in-demand programming languages in the world today. Python is so flexible and versatile that it is used for nearly every job that a programming language can do. Python powers desktop applications, is used for Linux system scripting and automation, acts as a glue language between Linux applications, is a supplemental scripting language in large programs like GIMP, Blender, and Autodesk Maya, performs crucial scientific and mathematical calculations, and runs some of the web's largest sites like Quora, Reddit, and Dropbox.

Eclipse is a powerful and feature-rich IDE for Java developers, but the versions packaged with Debian and Ubuntu lag far behind the latest releases. In fact, the version shipping with Ubuntu 16.04 was released in 2012 and was discontinued quite some time ago. Despite the fact that both Ubuntu and Debian don't package and ship new versions of it anymore, Eclipse is still easily available to users of both distributions. You just have to go about getting it a different way, and the Eclipse developers have a great solution for this.

Two of the most popular and highest quality media programs available for Linux are not available through Fedora's default repositories. Of course, these are no other than Kodi and VLC, and they are available on Fedora through RPM Fusion. Kodi, which was previously known as XBMC, has boomed in popularity as of late with both Linux and mainstream audiences.

Steam is easily the most popular PC gaming client, and with hundreds of titles available for Linux, it's not wonder why Linux gamers would want to install and use it. This is easier on some distributions than others, especially considering that Valve, the company behind Steam, officially targets Ubuntu and Debian. Fedora users won't find Steam anywhere in the official Fedora repositories. This is mostly because of Fedora's strict free software policies. It is available through a reliable third-party repository, though, and it runs great when you get it set up.

The latest AMDGPU drivers launched from AMD only a few short days ago bringing changes like FreeSync support and additional support for mobile chipsets as well as the obvious performance improvements. Like the previous versions of the proprietary AMDGPU driver, only "Enterprise Grade" distributions are supported, so you won't find official Ubuntu 16.10 support just yet. Ubuntu 16.04 is continuing to be supported, and that will be the target of this guide.
