The “Welcome to Interconnect” keynote kicked off the first day of IBM Interconnect 2017.

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.

IBM Interconnect 2017 is coming up next month in Las Vegas.

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.

I was in Barcelona last week for two big events: the OpenStack Summit and the OpenPOWER Summit.

Thanks to everyone who attended my talk at the OpenStack Summit in Barcelona!

There are lots of efforts underway to get students (young and old) to learn to write code.

Welcome to the fourth post in the series of What’s Happening in OpenStack-Ansible (WHOA) posts that I’m assembling each month.

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

Day two of IBM Edge 2016 is all done, and the focus has shifted to the individual.

I am here in Las Vegas for IBM Edge 2016 to learn about the latest developments in POWER, machine learning, and OpenStack.

IBM Edge 2016 starts next week in Las Vegas with an emphasis on changing how we think about technology.

I’ve recently updated this blog and icanhazip.

Welcome to the third post in the series of What’s Happening in OpenStack-Ansible (WHOA) posts that I’m assembling each month.

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.

This post is the second installment in the series of What’s Happening in OpenStack-Ansible (WHOA) posts that I’m assembling each month.

If you want to learn more about load balancers and security hardening in OpenStack clouds, join me on Thursday for the Rackspace Office Hours podcast1!

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.

The Red Hat Summit starts this week in San Francisco, and a few folks asked me about the sessions that they shouldn’t miss.

With the upcoming Red Hat Summit 2016 in San Francisco almost upon us, I decided to update the old SELinux shirts with two new designs:

The world of OpenStack moves quickly.

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.

Although there are a few weeks remaining before Fedora 24 is released, you can test out the Fedora 24 Beta release today!

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.

OpenStack comes home to Austin on Monday for the OpenStack Summit!

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.

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.

Thanks to all of the contributors that helped make a new release of supernova possible!

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