18F pushes for an even more open 'open source' rule

"Open source by default" ought to apply not only to code developed by government agencies, but also to virtually all code that vendors supply the government, a developer with GSA's startup urged.

The government startup that develops all of its code in the open wants the rest of government to follow suit.

Following the March 10 publication of a new draft Federal Source Code policy, the General Services Administration's 18F penned a response to one of federal CIO Tony Scott's questions.

Would "open source by default" be the way to go for federal code?

Absolutely, 18F Developer Eric Mill responded.

"Good software practices, such as writing appropriate documentation and separating passwords from the software which uses them, are good for all software and not unique to open source software," Mill wrote. "However, working in the open makes following these practices more consistent and more likely, even for the most competent staff — and when mistakes are made, working in public makes it more likely that they will be spotted and corrected early."

The draft federal policy, however, requires 100 percent open sourcing only for code developed in-house. When custom code is developed by third parties, agencies would have to release only 20 percent to the public.

There shouldn't be a distinction between internal and external development, Mill argued.

"This would eliminate entire classes of metrics that the White House would otherwise need to measure, and greatly reduce the overhead of implementing and overseeing this policy for OMB and agencies alike," he wrote.

If agencies need to keep vendor-developed code proprietary, they ought to go through a written justification process, Mill's response suggested.
