Accelerating Datacenter Energy Efficiency by Leveraging FreeBSD as Your Server OS
Explore how FreeBSD aids datacenter energy goals, promoting efficiency in design & operation, while supporting industry & government initiatives.
FreeBSD History – Understanding the Origins of DTrace
DTraceis a powerful tool for system administrators to diagnosis system issues without unduly impacting performance. DTrace became part of FreeBSD with the release of FreeBSD 7.1 in 2009—two years before Oracle began porting DTrace, and nine years before Oracle eventually solved the inherent CDDL vs GPL license conflict.
FreeBSD vs. Linux – Tracing and Troubleshooting
When troubleshooting a Linux or FreeBSD system, you need to be able to probe the system to find answers as to why it is behaving in a particular way. In this article, we’ll provide an overview of some of the basic tools and introduce the FreeBSD equivalents of common Linux tracing and troubleshooting tools.
Sysadmin Series – How to Catch a Bitcoin Miner
What first looked like some CPU oddity in a monitoring graph became a full-fledged hunt for a bitcoin miner. Figuring out what happened and how they were operating is part of the investigation. Collecting evidence to make a case soon became akin to a detective story.
Automation and Hacking Your FreeBSD CLI
The more we automate, the more we can save time and boost our productivity to higher levels. In this article we plan on looking at how to build more human-readable outputs in FreeBSD by leveraging tools like libxo to drive better output for automation APIs.
OpenZFS – Data Security vs. Integrity
Data security is about preventing data from being disclosed, ensuring that only the correct people can access it. Data integrity ensures the data is correct, that it has not become corrupt due to hardware failure or other issues. With ZFS, you can get both.
FreeBSD vs. Linux – 5 Factors When Considering FreeBSD vs Linux – Package Management
The popularity of package managers permeates all Unix distributions. Yet there are subtle differences in the approach that Linux vs. FreeBSD take in handling packages. How does Linux compare to FreeBSD’s way of managing packages? We have identified key points to consider in the software lifecycle management of both in the article below.
FreeBSD vs. Linux – Key Differences Between FreeBSD and Linux Networking
The question isn’t as much “Should I choose FreeBSD or Linux”, the question should be “Which OS fits my needs best?”. In our most recent comparison article, we go over the two implementations of the networking stack and look at how Linux implements networking and how FreeBSD fares in most cases.
The Role of Operating Systems in Iot
The number of Internet of Things devices both in our homes and in the world has exploded in the last few years. Smart IoT devices can now replace everything from the humble light switch all expand all the way to smart lawnmowers, All of these devices are driven by an Operating System of some sort. What Operating Systems are available and what do you need to consider when selecting an OS for a new product?
FreeBSD vs. Linux – Virtualization Showdown with bhyve and KVM
The bhyve hypervisor makes it easy to run reliable, high-performance virtual machines on a FreeBSD host system. In this article, we test the performance of virtual machines running Windows, Linux, and FreeBSD itself under bhyve—and we compare and contrast with performance of the same virtual machines running under Linux’s well-known KVM hypervisor. Understanding the pros and cons of each hypervisor helps you make confident, informed decisions when deciding how to set up your virtualization hosts.
