SUMMARY

I’m a Linux Engineer with skills in database administration, system administration, application development and leadership. I enjoy connecting people with technology solutions that are easy to use, affordable, and sustainable over time. I'm familiar with, and a huge supporter of, the DevOps culture and how to make it work with a large team in a fast paced environment.

Information security has also been an interest of mine. As the Chief Security Architect for Rackspace, I led a team of senior Windows, Linux and networking engineers who were dedicated to increasing security within Rackspace and for our customers. We provided critical security advisement to the business as a whole and we fueled technical security projects that reduced risk, reduced product development cycle time, and increased customer confidence.

I was previously working on the OpenStack project and its integration with Citrix Xenserver and Nicira's networking stack. I also maintained our high-availability clusters, Debian packaging and various system tools and scripts. Our team created a highly automated continuous integration system with Jenkins that allowed us to test and deploy new code much more rapidly than before. 

Use the mogrify program to resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more. This tool is similar to convert except that the original image file is overwritten (unless you change the file suffix with the -format option) with any changes you request. See Command Line Processing for advice on how to structure your mogrify command or see below for sample usages of the command.

PhantomJS is a headless WebKit scriptable with a JavaScript API. It has fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

Unless you are a MySQL performance tuning expert, it can be enormously challenging and somewhat overwhelming to locate and eliminate MySQL bottlenecks. While many DBAs focus on improving the performance of the queries themselves, this post will focus on the highest-impact non-query items: MySQL Server Performance and OS Performance for MySQL.

Most options can be set using their actual names in the my.cnf.

The zgrep program is available for Linux (and perhaps some Unix too). This will decompress the files and then grep through them.

Arch Wiki has a page about MediaWiki that provides more details, but lacks paste-able code to quickly get things up and running. So the focus here is on just the basic recipe for a quick installation. Note the following commands should be run as root user (to get into root run su, for example).
