U.S. Defense Department Promotes Open Source
An open memo from the U.S. DoD declares that open source software is no worse than traditional software, perhaps even more useful.
The DoD needs to take faster steps at increased care and maintenance of its software infrastructure, where open source provides a marked advantage, according to acting DoD chief information officer David M. Wennegren in his recent memo to defense entities. In it he asserts that knowledge gaps and misunderstanding have prevented effective use of open source in the DoD. His "Clarifying Guidance Regarding Open Source Software (OSS)" addresses joint chiefs of staff, the defense secretariat and other decision-makers in IT, acquisitions and related entities, and includes some enlightening material.

The memo recommends taking a good look at open source software to determine which market products can best address a stated task. Wennegren states his case with seven arguments for open source: its (1) broad peer review provides stability and reliability, (2) adaptability to changing conditions, (3) independence from single developer reliance, (4) unrestricted licensing, (5) cost growth mitigation, (6) shared maintenance opportunities and (7) rapid prototyping and experimentation opportunities.
Wennegren's memo goes on to dash some current misconceptions among
DoD folks about open source. For example, he clarifies that "many open
source licenses permit the user to modify OSS for internal use without
being obligated to distribute source code to the public. However, if
the user chooses to distribute the modified OSS outside the [DoD], then
some OSS licenses (such as the GNU General Public License) do require
distribution of the corresponding source code to the recipient of the
software." In other words, if further developed open source code is to
be used only internally (is classified), the source code need not be
distributed externally.
The six-page document dates from October 16, 2009 and is available off the DoD FOSS webpage, which also includes the FAQ and a document from 2003
that Wennegren claims resulted in some misconceptions he wanted to
resolve with the current memo. The older document likewise targeted OSS
in the DoD, but focused almost entirely on compliance with policies
instead of providing clarification.
