Some of the best technology is a moving target. When technology stagnates, society tends to outpace and outgrow it. Linux, the widely used open source operating system (OS), is a foundational technology and the basis for some of the most progressive modern computing ideas. So, while it’s startlingly unchanged after three decades of development, it also allows adaptation. As a result, Linux is in a unique position of being both a sound investment in skills because it doesn’t change and a seemingly eternal driving force for new skills to learn.

The year 2020 has been a strange one—by any measure—but for Linux, it’s been a typical development cycle. Here’s a look back at the year so far and a review of what you need to know about Linux in 2020.

ZFS on Linux

The ZFS filesystem offers integrity checking for data and metadata, redundancy with mirroring, support for up to 256 trillion yobibytes of storage, hardware-accelerated native encryption, and efficient replication. ZFS is a Sun Microsystems innovation that, unfortunately, has a license that prohibits it from being bundled with Linux by default. However, the OpenZFS group has ported the project to BSD and Linux so that you can run ZFS on anything from your laptop to your data center.

Getting started with ZFS is surprisingly simple on Fedora Linux, as Sheng Mao demonstrates in his article on setting up ZFS on Linux.
