Although there are a few weeks remaining before Fedora 24 is released, you can test out the Fedora 24 Beta release today! This is a great way to get a sneak peek at new features and help find bugs that still need a fix.
The Fedora Cloud image is available for download from your favorite local mirror or directly from Fedora’s servers. In this post, I’ll show you how to import this image into an OpenStack environment and begin testing Fedora 24 Beta.

Let’s Encrypt has taken the world by storm by providing free SSL certificates that can be renewed via automated methods. They have issued over 1.4 million certificates since launch in the fall of 2015.
If you are not familiar with how Let’s Encrypt operates, here is an extremely simple explanation:
Create a private key Make a request for a new certificate Complete the challenge process You have a certificate! That is highly simplified, but there is plenty of detail available on how the whole system works.

I’ve decided to start a series of posts called “Chronicles of SELinux” where I hope to educate more users on how to handle SELinux denials with finesse rather than simply disabling it entirely. To kick things off, I’ll be talking about dealing with web content in the first post.
First steps If you’d like to follow along, simply hop onto a system running Fedora 21 (or later), CentOS 7 or Red Hat Enterprise Linux 7.

For those of you in the market for a cheap webcam for videoconferencing or home surveillance, the Logitech C270 is hard to beat at about $20-25 USD. It can record video at 1280×960 and it’s fairly good at low light levels. The white balance gets a bit off when it’s bright in the room but hey — this camera is cheap.
ZoneMinder can monitor multiple cameras connected via USB or network.

Docker is a hot topic in the Linux world at the moment and I decided to try out the new trusted build process. Long story short, you put your Dockerfile along with any additional content into your GitHub repository, link your GitHub account with Docker, and then fire off a build. The Docker index labels it as “trusted” since it was build from source files in your repository.
I set off to build a Dockerfile to provision a container that would run all of the icanhazip services.
