Joshua (JD) is a long time Open Source advocate and entrepreneur dating back to the early days of Professional Open Source. From the valleys of Usenet he sold custom Linux servers with a whopping 16 MB of ram and 1GB SCSI drives. These were the days of SLS and many, many floppy disks. Through the years he has help found multiple Internet Service Providers as well as eventually launching his own firm, Command Prompt, Inc.. Command Prompt has over the years become one of the predominant privately owned PostgreSQL support and Consulting firms.

An avid public speaker and writer, he is also the founder of United States PostgreSQL, PgConf (PostgresConf) and More than a Refresh: A podcast about the most interesting people you haven't met. He currently resides off-grid in Montana.

He divides his time between Command Prompt, off-grid projects, mentoring/leadership roles and helping those who wish to become successful, define what that means for them.
