I started my open source work from Oregon, USA working on a project in the "Republic" of Texas. While that, at first glance, does not sound international in nature, I can assure you that Oregon and Texas might as well be different countries. I experienced both the joy and frustration of working with users from both places that had big cultural differences, as well as overlapping needs. This early experience laid the groundwork for the future, where I got to work at the international level on OpenEMR, an electronic healthcare records system. read more

Across the history of data analytics, marquee-level applications have always given rise to useful front ends and connectors that extend what the original applications were capable of. For example, the dominance of the spreadsheet gave rise to macros, plugins, and extensions. Likewise, the rise of SQL database applications ushered in database front ends, plugins, and connectors. Now, Big Data titan Hadoop is inspiring its own ecosystem of powerful extensions and front ends.

We send our programs out into the world to be run by anyone for any purpose. Think about that: by anyone, for any purpose.
