To what do we owe the honor? Have the people sworn to protect us from fanatics in caves suddenly gained open source religion? Are they trying to ingratiate themselves with a new Administration which looks favorably on open source? Or are they trying to take it over, infiltrate it?
The answers to these questions are important, as is your speculation, because the welcome these projects get from the open source community will likely determine how much help they get. Reputation is vital in open source, and government often has a poor one.
Then there's the quality of the offering itself. I don't see anything in Eureka Streams I can't do in Drupal, or a number of other high-quality open source projects that have existed for years. Lockheed has reinvented the wheel -- why? And why should I help them push it up the hill?
The author of Eureka Streams, who goes by the name Sterlecki at Github, has left no previous tracks there. Linkedin lists the same picture as belonging to Steve Terlecki, a Lockheed software developer.
The stuff's legit, so we're left again with the question of motive. Is the military-industrial complex reaching out to open source, is this just proof of press reports showing our spy efforts have more bloat in them than a Macy's Thanksgiving float, are we being co-opted, or am I just too suspicious?
