Denver Open Source Users Group

Matthew McCullough, Tim Berglund, Mike Barker, Dan Hillenbrand, Mark Nelson, and Jordan McCullough welcome you to the Denver Open Source Users Group site. Shortened to the acronym DOSUG by our members, this group was founded in 2005 to help developers share information about Open Source projects in use at our day jobs.

Join us »


The DOSUG board welcomes speaker submissions on anything open source. Just send the board an email describing your topic, the audience requirements, your speaking experience, and ability to travel to Denver, CO if you have an OSS topic you are passionate about.

Propose a talk »


Slides from past presentations are shared for any presenter willing to share them. Slide uploads are hosted and tagged as DOSUG at SpeakerDeck and SlideShare.

Mailing List

DOSUG uses a based member list for meeting notifications and member communication. In the spirit of education purity, we never sell, rent or disclose any aspect of member data, and we only send email regarding DOSUG events.

Joining the Meetup group is the best way to RSVP for upcoming events so that we'll be able to request sufficient food from our meal sponsor. In the rare case of weather-related hindrances, this list will also be used to notify members of event cancellations.

Our meetings are made possible by our generous sponsors, Their support of product giveaways, meeting room space, travel, speaker time, and food are greatly appreciated.
