IBM Edge 2016 is almost over and I’ve learned a lot about Power 8 this week.

OpenStack’s compute service, nova, manages all of the virtual machines within a OpenStack cloud.

I ran into an interesting problem recently in my production OpenStack deployment that runs the Mitaka release.

The OpenStack Zuul system has gone through some big changes recently, and one of those changes is around how you monitor a running CI job.

Most of the recent Fedora upgrades have been quite smooth.

The 2016 Red Hat Summit is underway in San Francisco this week and I delivered a talk with Robyn Bergeron earlier today.

Lots of work has gone into the openstack-ansible-security Ansible role since I delivered a talk about it last month at the OpenStack Summit in Austin.

NOTE: This post is a work in progress.

When you’re ready to commit code in an OpenStack project, your patch will eventually land in a Gerrit queue for review.

I’ve gone on some mini-rants in other posts about starting daemons immediately after they’re installed in Ubuntu and Debian.

Authenticating to a wired or wireless network using 802.

Today is the second day of the OpenStack Summit in Austin and I offered up a talk on host security hardening in OpenStack clouds.

Back in 2011, I decided to try out a new method for hosting my websites and other applications: colocation.

When I started Thunderbird today, it opened three windows.

On most IPv6-enabled networks, network addresses are distributed via stateless address autoconfiguration (SLAAC).

Let’s Encrypt has taken the world by storm by providing free SSL certificates that can be renewed via automated methods.

UPDATE: The fixed version of mutter is now in the Fedora updates repository.

After getting a bit overzealous with cleaning up bookmarks in Chrome, I discovered that I deleted a helpful Gerrit filter for OpenStack reviews.

I’m always interested to talk to college students about technology and business in general.

I’m a big fan of the pyenv project because it makes installing multiple python versions a simple process.

Although I use GNOME 3 as my desktop environment, I prefer KDE’s kwallet service to gnome-keyring for some functions.

I’ve talked about predictable network names (and seemingly unpredictable ones) on the blog before, but some readers asked me how they could alter the network naming to fit a particular situation.

Updating Dell PowerEdge firmware from Linux is quite easy, but it isn’t documented very well.

Working with open source software is an amazing experience.

I’ve been a big fan of Thunderbird for years, but it lacks features in some critical areas.

I was recently asked to talk to Computer Information Systems students at the University of the Incarnate Word here in San Antonio about information security in the business world.

I spent some time working with macvlan interfaces on KVM hypervisors last weekend.

Switching to systemd-networkd for managing your networking interfaces makes things quite a bit simpler over standard networking scripts or NetworkManager.

The blog posts have slowed down a bit lately because I’ve been heads down on a security project at work.

Earlier today, I wrote a post about my first thoughts on the Supermicro 5028D-T4NT server.

I’ve recently moved over to Rackspace’s OpenStack Private Cloud team and the role is full of some great challenges.

If you’re running Fedora 22 and you’ve recently updated to systemd-219-24.

Although Time Warner Cable is now Spectrum and wide-dhcpv6 is quite old, this post is still what I’m using today (in 2019)!

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.

I’ve had a great time talking to people about my “Be an inspiration, not an impostor” talk that I delivered in August.

This post originally appeared on the Fedora Magazine blog.

Thanks to all of the people who attended my “Be an inspiration, not an impostor” talk at Texas Linux Fest 2015.

I talked a bit about systemd’s network device name in my earlier post about systemd-networkd and bonding and I received some questions about how systemd rolls through the possible names of network devices to choose the final name.

I’ve written about systemd-networkd in the past and how easy it can be to set up new network devices and tunnels.

It seems like there’s a new way to run containers every week.

Fedora Flock 2015 is still going here in Rochester, New York, and I kicked off our second day with a keynote talk about overcoming impostor syndrome.

I started working on the Ansible CIS playbook for CentOS and RHEL 6 back in 2014 and I’ve made a few changes to increase quality and make it easier to use.

I decided to change some of my infrastructure back to KVM again, and the overall experience has been quite good in Fedora 22.

I’ve recently set up a Fedora 22 firewall/router at home (more on that later) and I noticed that remote ssh logins were extremely slow.

My upgrade to Fedora 22 on the ThinkPad X1 Carbon was fairly uneventful and the hiccups were minor.

I stumbled upon a strange bug at work one day and found I couldn’t connect to our wireless access points any longer.

GNOME 3 generally works well for me but it has some quirks.

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.

My older post about rotating GNOME’s wallpaper with systemd timers doesn’t seem to work in Fedora 22.

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.
