If you’re on the latest Fedora release, you’re already running lots of modern packages. However, there are those times when you may want to help with testing efforts or try out a new feature in a newer package.
Most of my systems have the updates-testing repository enabled in one way or another. This repository contains packages that package maintainers have submitted to become the next stable package in Fedora. For example, if there is a bug fix for nginx, the package maintainer submits the changes and publish a release....
Switching to systemd-networkd for managing your networking interfaces makes things quite a bit simpler over standard networking scripts or NetworkManager. Aside from being easier to configure, it uses fewer resources on your system, which can be handy for smaller virtual machines or containers.
Managing tunnels between interfaces is also easier with systemd-networkd. This post will show you how to set up a GRE tunnel between two hosts running systemd-networkd.
Getting started You’ll need two hosts running a recent version of systemd-networkd....
Woot suckered me into buying a 4K display at a fairly decent price and now I have a Samsung U28D590D sitting on my desk at home. I ordered a mini-DisplayPort to DisplayPort from Amazon and it arrived just before the monitor hit my doorstep. It’s time to enter the world of 4K displays.
The unboxing of the monitor was fairly uneventful and it powered up after small amount of assembly. I plugged my mini-DP to DP cable into the monitor and then into my X1 Carbon 3rd gen....
I picked up a copy of Robert Love’s book, Linux Kernel Development, earlier this year and I’ve worked my way through it over the past several weeks. A few people recommended the book to me on Twitter and I’m so glad they did. This book totally changed how I look at a system running Linux.
You must be this tall to ride this ride I’ve never had formal education in computer science or software development in the past....
When you upgrade packages on Red Hat, CentOS and Fedora systems, the newer package replaces the older package. That means that files managed by RPM from the old package are removed and replaced with files from the newer package.
There’s one exception here: kernel packages.
Upgrading a kernel package with yum and dnf leaves the older kernel package on the system just in case you need it again. This is handy if the new kernel introduces a bug on your system or if you need to work through a compile of a custom kernel module....
After a boatload of challenges with what I thought would be my favorite Linux laptop, the Dell XPS 13 9343, I decided to take the plunge on a new Lenovo X1 Carbon (3rd gen). My late-2013 MacBook Pro Retina (MacbookPro11,1) had plenty of quirks when running Linux and I was eager to find a better platform.

[][1]I’m far from being a kernel developer, but I found myself staring down a [peculiar touchpad problem][2] with my new Dell XPS 13. Before kernel 3.17, the touchpad showed up as a standard PS/2 mouse, which certainly wasn’t ideal. That robbed the pad of its multi-touch capabilities. Kernel 3.17 added the right support for the pad but freezes began to occur somewhere between 3.17 and 3.19.
Bisecting It became apparent that bisecting the kernel would be required....
The thought of using Linux as a manager in a highly Windows- and Mac-centric corporate environment isn’t something to be taken lightly. Integrating with Active Directory, wrangling email with Microsoft Exchange, and taming quirky Microsoft office documents can be a challenge even with a well-equipped Mac. I decided to make a change after using a Mac at Rackspace for six years.
Let’s get one thing straight: I’m not a Windows or Mac basher....
It’s been a little while since I last posted about installing Xen on Fedora, so I figured that Fedora 19’s beta release was as good a time as any to write a new post. To get started, you’ll need to get Fedora 19 installed on your favorite hardware (or virtual machine).
Install the Xen hypervisor and tools. Also, ensure that both of the necessary daemons are running on each boot:...
If you haven’t noticed already, full Xen dom0 support was added in the Linux 3.0 kernel. This means there’s no longer a need to drag patches forward from old kernels and work from special branches and git repositories when building a kernel for dom0.
Something else you might not have noticed is that the Fedora kernel team has quietly slipped Linux 3.0 into Fedora 15’s update channels in disguise. Click that link, scroll down, and you’ll see “Rebase to 3....
