Want to make a change in an open source project? Take the Nike approach and Just Do It. 👟

Some people say I just enjoy the sound of my mechanical keyboard too much. 🤭 I see it as a simpler, more consistent workflow.

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

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

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

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.

Working with open source software is an amazing experience.

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 started supernova a little over three years ago with the idea of making it easier to use novaclient.

I’ve been getting involved with the Fedora Security Team lately and we’re working as a group to crush security bugs that affect Fedora, CentOS (via EPEL) and Red Hat Enterprise Linux (via EPEL).

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.

We’re all familiar with live booting Linux distributions.

As I wait in the airport to fly back home from this year’s Red Hat Summit, I’m thinking back over the many conversations I had over breakfast, over lunch, and during the events.

I’ve made posts about the DevOps Weekly mailing list before.

A coworker heard me grumbling about Linux system administration standards and recommended that I review the CIS Security Benchmarks.

Python’s virtual environment capability is extremely handy for situations where you don’t want the required modules for a particular python project to get mixed up with your system-wide installed modules.

I had a peculiar situation today where I cloned a repository into a directory which was inside another repository.

It’s no secret that I’m a fan of Twitter and OpenStack.

While working on multiple nova (OpenStack Compute) environments at Rackspace, I found myself thrashing between multiple terminal windows where I had exported environment variables for python-novaclient to use.

My quest to get better at Python led me to create a new project on GitHub.

I found myself stuck in a particularly nasty situation a few weeks ago where I had two git branches with some commits that were mixed up.

A fellow Racker showed me httpry about five years ago and I’ve had in my toolbox as a handy way to watch HTTP traffic.

The discussions about the paravirt_ops, or “pvops”, support in upstream kernels at Xen Summit 2010 last month really piqued my interest.

Most web developers expend a lot of energy optimizing queries, reducing the overhead of functions, and streamlining their application’s overall flow.

I finally remembered this book when someone asked me about how to get started with PHP and MySQL development.

I’ve been flooded with requests for MySQLTuner and I’ve answered them this weekend.

If there’s one question I get a lot, it would be “Hey, how can I speed up MySQL?

On some servers, you may notice that MySQL is consuming CPU and memory resources when it’s not processing any queries.

If you need to strip query strings from a URL with mod_rewrite, you can use a rewrite syntax such as the following:

To install PayFlowPro, you will need a few things:

If you can’t use PHP to force HTTPS, you can use mod_rewrite instead.

To force HTTPS with a PHP script, just put this snippet near the top:

I rarely try to toot my own horn, but I’ve created a pretty handy site.
