Professional Python® and open source consulting and programming since 2004
Mission

Our goal since 2004 has been to advance the use of open source software and related technology. We have maintained this focus by successfully undertaking a variety of professional endeavors throughout the years including, but not limited to the following: Alex Clark is the creator and project lead for Pillow; we are the organizers and leaders of DC Python, a 501(c)(3) organization; we were the lead organizers and hosts of Plone Conference 2008; we consistently provide successful open source software development, consulting, training, hosting and support for numerous organizations in the U.S. and all over the world, from Amtrak to USAID. We will continue to reinforce and expand our commitment, outreach, and involvement with both open source technology and the community that depends on it.

Pillow

Python Imaging Library (fork)

In 2010, Alex Clark created Pillow, a software development fork of the venerable Python Imaging Library (PIL). As of early 2017, Pillow has been downloaded over 15 million times. The Pillow library can be found in many major Linux distributions such as Ubuntu and Fedora Core. It is used by many Fortune-100-serving companies and was even used in April 2021 on the Mars 2020 Helicopter Mission!

Book

The approach presented in Alex Clark's instructional text book Plone 3.3 Site Administration helps users create, deploy, and maintain all versions of Plone up to and including the latest version.

The text covers Plone basics from a site administrator's perspective including (but not limited to) instructions on how to:

  • Learn the use of Buildout to develop, deploy, and maintain a modern Plone site.
  • Enhance the functionality and appearance of your web site by using third-party add-ons.
  • Learn to use many useful Buildout recipes available to download from the Python Package Index.

Wagtail

We have recently added Wagtail to our list of preferred frameworks for building Python-based web applications. It is a CMS framework rather than an out-of-the-box-CMS ("built by developers for developers"). We are highly proficient in developing with Wagtail and are able to deliver impressive results using this adaptable technology.

DC Python

In 2008, we created ZPUGDC, Inc., a 501(c)(3) non-profit organization known as the DC Python User's Group. We created this organization in an effort to expand our outreach and give back to the users and supporters of open source technology. DC Python is focused primarily on serving members of the local Washington, D.C., Maryland, and Virginia Python community, but we also support a larger area and scope of open-source technology efforts, worldwide. One of our most significant global contributions was the organization and hosting of the international Plone Conference 2008.

We continue to maintain our leadership responsibilities in the DC Python organization. We provide management and facilitate regular meetings, sprints, and many other Python-related events and activities for the local Python community. We assume all responsibilities for the organization ensuring a continued commitment to its mission.
