Web ads and ad scripts can slow down your system and gum up your web experience. Browser-based ad-blockers are useful for controlling many types of popups and banners, but they are less effective with ads built into applications – and they are often difficult to implement on mobile devices. This month we look at a couple of alternative tools for blocking ads at the network level: Pi-hole and Privoxy.

Are tiling window managers still relevant for today's desktop? This month we explore the possibilities of the tiling paradigm with a modern Linux built for tiling.

Home automation is no longer the stuff of science fiction. This month we explore some versatile tools for Linux users who are interested in IoT but don't want to surrender the freedom of open platforms and open source.

Vector graphics applications like Inkscape are a popular option for creating scalable graphics. Could these tools be even better? As is often the case, the science is out in front of the mainstream. We show you some innovations that could revolutionize tomorrow's graphics apps.

Sure you've heard of the Tor Browser, but what about OnionShare? This cool tool for the invisible web lets you share files without revealing your identity. 

The bad news is that disasters happen. The good news is that Linux has a variety of powerful backup tools that will protect you when disaster strikes. This month, we cover some backup apps for the†Linux environment, including Rclone, restic, and rsnapshot.

Hardware resources keep expanding, and mainstream OS systems also keep expanding, sucking up the newfound space with more and better bloatware. But many users would rather escape the arms race and keep it simple. This month, we review some of the top resource-conscious small distros.

This month we show you how to hack a smart plug, reflash the firmware, and control it from a nearby Linux computer. If you love the concept of the Internet of Things but you don't like spending a lot of money on proprietary gadgets, read on for our low-tech high-tech solution.

Energy efficiency studies often focus on hardware, but what about the software? As it turns out, software tools created for similar tasks sometimes use energy very differently.

This month we share some advanced techniques for working with the famous Git remote version control system used by open source developers.

Modern filesystems make it easy to take a snapshot – a precise copy of your data at a moment in time. This month we review some leading Linux snapshot tools.

As computers get more powerful and computer applications get bigger and more ungainly, users end up with the same question no matter how many times they upgrade: How do I make the most of my system resources by tuning up system performance? This month we explore some tools that offer a window into the performance and health of your Linux system: Netdata and perf.

The FOSS tool known as VirtualBox is a popular alternative for easy virtualization in Linux. Many users are satisfied to spin up a virtual machine and start a system inside it,†but VirtualBox can do so much more. We show you some advanced tricks with VirtualBox. 

That drab default boot menu on your Linux computer isn't just boring; it also could be confusing users and obscuring important boot choices.
