The Lenovo ThinkPad T490 is a great laptop, but it comes with some discrete GPU challenges.

Fedora 17’s code name was Beefy Miracle and it had a great mascot. You can see it at boot time with a few quick changes.

My new T490 with a 10th generation Intel CPU and a discrete NVIDIA MX250 has arrived! Installing Linux creates some interesting challenges.

Openshift (and Kubernetes) allow you to run jobs on schedule, but these jobs can fail from time to time. You can monitor them from bash!

Monitor the power consumption of your CyberPower UPS and display the live output in your Linux desktop’s status bar.

Lower your CPU usage and increase battery life when you watch certain videos by using Chromium with VAAPI support.

All of your GNOME and gtk applications are configured in i3 with a few simple tricks.

Monit is a tried-and-true monitoring daemon that is easy to deploy. Add it to OpenShift to make monitoring even easier.

Many cloud providers give you lots of memory with each instance and you can speed up tests and builds by using a ramdisk.

Buildah and podman work well with the vfs storage driver, but the default mount options can cause problems.

Fedora 30 is a great Linux distribution for cloud platforms, but it needs a little work to perform well on Google Compute Engine.

Welcome! #This page is a work in progress!

Another Texas Linux Fest has come and gone!

My team at Red Hat depends heavily on GitLab CI and we build containers often to run all kinds of tests.

My team at Red Hat builds a lot of kernels in OpenShift pods as part of our work with the Continuous Kernel Integration (CKI) project.

My work at Red Hat involves testing lots and lots of kernels from various sources and we use GitLab CE to manage many of our repositories and run our CI jobs.

After writing my last post on my IPv6 woes with my Pixel 3, some readers asked how I’m handling IPv6 on my router lately.

We have two Google Pixel phones in our house: a Pixel 2 and a Pixel 3.

I recently picked up a Dell Optiplex 7060 and I’m using it as my main workstation now.

The i3 window manager is a fast window manager that helps you keep all of your applications in the right place.

DevConf.CZ 2019 wrapped up last weekend and it was a great event packed with lots of knowledgeable speakers, an engaging hallway track, and delicious food.

Fedora 29 now has kernel 4.

The Home Assistant project provides a great open source way to get started with home automtion that can be entirely self-contained within your home.

Managing iptables gets a lot easier with firewalld.

Firefox has some great features, but one of my favorites is the ability to disable autoplay for videos.

Repeaters are a great way to get into ham radio, but they can be tricky to use for new amateur radio operators. This post explains how to get started.

Environment variables are easy to add to OpenShift deployments, but a more secure way to add these variables is by referencing a secret.

I’m at the 2018 Red Hat Summit this week in San Francisco and I am enjoying the interactions between developers, executives, vendors, and engineers.

Walt Disney said it best:

If you’re on the latest Fedora release, you’re already running lots of modern packages.

The Overland Expo in Asheville last year was a great event, and one of my favorite sessions covered the basics about radio communications while overlanding.

After a recent OpenStack-Ansible (OSA) deployment on CentOS, I found that keepalived was not starting properly at boot time:

The latest release of the Red Hat Enterprise Linux Security Technical Implementation Guide (STIG) was published last week.

I’ve been working through some patches to OpenStack-Ansible lately to optimize how we configure yum repositories in our deployments.

Thunderbird is a great choice for a mail client on Linux systems if you prefer a GUI, but I had some problems with fonts in the most recent releases.

I have a CyberPower BRG1350AVRLCD at home and I’ve just connected it to a new device.

Tons of improvements made their way into the ansible-hardening role in preparation for the OpenStack Pike release next month.

Thunderbird can connect to an LDAP server and autocomplete email addresses as you type, but it needs some adjustment for some LDAP servers.

The interest in the openstack-ansible-security role has taken off faster than I expected, and one piece of constant feedback I received was around the name of the role.

I merged some initial Debian support into the openstack-ansible-security role and ran into an issue enabling AppArmor.

I opened up a noVNC console to a virtual machine today in my OpenStack cloud but found that the console wouldn’t take keyboard input.

Although OpenStack-Ansible doesn’t fully support CentOS 7 yet, the support is almost ready.

DISA’s final release of the Red Hat Enterprise Linux (RHEL) 7 Security Technical Implementation Guide (STIG) came out a few weeks ago and it has plenty of improvements and changes.

It all started shortly after I joined Rackspace in December of 2006.

NOTE: The opinions shared in this post are mine alone and are not related to my employer in any way.

My OpenStack cloud depends on Ubuntu, and the latest release of OpenStack-Ansible (what I use to deploy OpenStack) requires Ubuntu 16.

My new ThinkPad arrived this week and it is working well!

All systems running systemd come with a powerful tool for reviewing the system journal: journalctl.

When I came back from the holiday break, I found that the openstack-ansible-security role wasn’t passing tests any longer.
