The "when requested" is the point I was making. FOIA is how you request such software. If you want a copy of the elisp libraries I wrote to automate creation of field devices on military fuel farm SCADA systems, you'll have to submit an FOIA request. Unless someone at the DoD decides to share it out of the goodness of their hearts, you have to ask for it.
Sounds fascinating! Other than the FOIA bit. Do you have a blog post or something with more detail about this work?
Naw, it's not really all that interesting. A SCADA system has a bunch of field devices it needs to talk to. Most SCADA software has some method of importing lists of device information and creating objects from it.
My engineer gives me a list of (for example) valve actuators on a site. I open that list in Emacs, manipulate it a bit, and then use it as input to a function I've written. That function generates a CSV file with things like tag name, Modbus ID, polling method, etc. that I can import into Wonderware. It's considerably faster and less error prone than manually creating and configuring hundreds of instances.
I say it's not interesting because most people in my position write little bits of code like this to automate the repetitive parts of our jobs. I just do it with elisp instead of Excel or Python.
I guess I should have been clearer - the "private repository" mentioned in that bill only has to be available for government employees, and even then only on request. Public repositories are an option, but the government doesn't have to choose that option. The main point is to encourage reuse within the government, not to be a source of free public domain software for the public.
Almost everything the government makes IS public domain, including the software.

Just because it's public domain doesn't mean they are obliged to make it available to the public. As noted above, they do have to make it available to other government agencies, but it's the government's choice to place it in a public repository. All public domain means is that if you happen to acquire a copy of it, you can do whatever you like with it.
