Over my almost 20 year career I have built a reputation as an industry leader, creating new trends and being results focused while representing the best interests of both the organization and those of my teams. In addition to my professional career I also have created, founded and built several large open source projects and communities in the open source realm with install counts in the millions of users. These projects include CentOS Linux, Caos Linux, Perceus, Warewulf and most recently Singularity. My core values include honesty, ethics, and integrity; Standards in which I hold both myself and my colleagues to.
Specialties: Linux (environment, services and deep system internals), open source, HPC, clustering, MPI, provisioning, scalability, system administration, architecture, automation, development (Perl, C, SQL, PHP, HTML, etc.), recruiting, team leadership, project leadership, management and public speaking.
I have taken part of a variety of open source projects over the years, and below are the ones I have had the honor of creating and leading and being part of.
Warewulf is a scalable systems management suite originally developed to manage large high-performance Linux clusters. Focused on general scalable systems management, it includes a framework for system configuration, management, provisioning/installation, monitoring, event notification, and more via a modular plugin architecture. Install the components and features you need or leverage the existing system configurations stored within Warewulf to create custom solutions to meet your particular needs.
Containers have taken the tech world by storm, and while they may be a fantastic alternative to virtual machines (when the hardware abstraction is not necessary), they are not a great fit for application portability. Until now....
Singularity combines software packaging models (such as RPM) with minimalistic containers to create very lightweight application bundles which can be simply executed and contained completely within their environment or be used to interact directly with the host file systems at native speeds.
A Singularity application bundle can be as simple as containing a single binary application or as complicated as containing an entire workflow and is as flexible as you will need.
Warewulf took a brief hiatus while I further developed it's provisioning functions under a new project (Perceus) and a corporate umbrella. After I finished developing Perceus it was determined that the best path forward is to continue with Warewulf using an open source (BSD) license under the funding of Lawrence Berkeley National Labratory.
Centos came from the Caos Foundation (which I started in 2002) and initially Centos was destined to be a build platform for the new RPM based community maintained distribution Caos Linux. When it was designed to be released to the public, it was originally coined as Caos-EL (Enterprise Linux) and it was renamed publicly in December 2003 to what it is known as today.
After founding the project I led it until 2005 and I was responsible for all of it's initial leadership, management, public outreach and partnerships during that period. Due to legal, political, and severely less then excellent people, I was forced to relinquish leadership of the project to a party in the UK (where it stayed until the core developers were able to regain control of the project). There might be some very entertaining stories to be shared over dinner and drinks among friends...
Now the project is one of the most utilized Linux distributions for servers and is run by Red Hat.
I work for the High Performance Computing Services (HPCS) group at Lawence Berkeley National Lab (http://scs.lbl.gov/).
