UNIX’s history was marred by power struggles and fights over its direction and core. This meant that at some point in time, different factions went to war to control the future of UNIX. As part of our recent write-up, we’re taking a look at the wars that shaped UNIX’s future and the events that followed.

A lot of great papers have been written throughout the history of FreeBSD. For most of the features you see today in a modern FreeBSD Operating System there is a corresponding paper that was written during its development or after its inclusion to document its addition.
Today, we’re looking at two of our favourite papers, trying to highlight their contribution to the FreeBSD Operating System.
We all know and have at least once used the top(1) command on FreeBSD to track information about our cpu and processes, but how many of you know what each field means? By default, top(1) displays the ‘top’ processes on each system and periodically updates this information every 2.0 seconds using the raw cpu use percentage to rank the processes in the list.
This article will give you some insight on how to better understand top (1).
We’ve all been there: that moment of panic when a system fails to boot back up. Perhaps there was a glitch with an upgrade. Maybe you’re wondering if you fumble-fingered a typo when you made that last change to loader.conf.
Fortunately, with FreeBSD and its built-in rescue mechanisms it is possible to quickly recover from most scenarios that prevent a system from booting into normal operation. And if you’re using OpenZFS, you can rest assured that your data is intact.
With this article, let’s take a look at some common recovery scenarios.
If you are eager to start FreeBSD development, but don’t know where to begin, this short guide is for you.
This article will provide some pointers into how some FreeBSD committers work on the Operating System and ports collection. We will discuss the hardware configurations that are used day to day to implement, build and test the operating system.

OpenZFS 2.0 has been released for a while now and, needless to say, FreeBSD 13 was shipped with OpenZFS 2.0. However, there are still questions about how the change from feature flags happened and why version 2.0 of OpenZFS was decided.
With this article, we’re hoping to clear the air around the release of OpenZFS 2.0.
In our previous articles, we introduced you to the basics of ZFS snapshot management, and explained concepts such as creating OpenZFS snapshots, restoring files from a snapshot, and deleting snapshots.
With this article, we dive a bit deeper into OpenZFS snapshot management with snapshot holds, clone creation and promotion, and assigning permissions to snapshot-related operations.
In this article, we’re talking about the OpenZFS SLOG. Find out, among others, about synchronous vs asynchronous writes and the ZIL, why you should use a SLOG and on what type of devices.

One of the newer OpenZFS features that became available with FreeBSD 12.0 is ZFS Channel Programs. This article addresses questions to clarify what a ZFS channel program is, why you should use it, what are the operations supported by channel programs, or what a channel program looks like. Follow our guide and resources to learn how to create your own Channel Programs.

Since its first release for the i386 processor in 1993, FreeBSD has been ported to run on a wide array of different CPU architectures and platforms. In this article, we will look at the youngest of these architectures on which FreeBSD currently runs: the RISC-V instruction set architecture.

RISC-V is a relatively new chip architecture that is quickly making its way in the tech world and is proving to be quite a rival for the existing well-known architectures.
Today, we will look at the history of RISC-V and how it differs from the other offerings.
With the release of FreeBSD 13, arm64 has been elevated to Tier 1 status. FreeBSD support for arm64 has grown steadily since the architecture was incorporated in 2015 based on work supported by the community, ARM and Marvell (then Cavium). Learn about processor performance, hardware factors, and Big.Little in our latest article.

FreeBSD/arm64 is the FreeBSD port to the 64-bit ARM architecture, also known as AArch64 or ARMv8. All supported FreeBSD releases include support for ARMv8 and there are many packages and ports (3rd party applications) available to support the software you normally deploy with FreeBSD.
