Well done to the Defence Science and Technology Laboratory at the UK ministry of Defence. They’ve started to release code on github.
I can’t imagine that getting approval for this was easy, and it probably required a fair amount of negotiation to get this far; but it’s a good sign for openness in government and hopefully it will be a good thing for both the government and the wider community.
Given that governments aren’t trying to make money selling software, open source seems an excellent fit. Hopefully we’ll see more stuff from them. (I imagine not the classified things though!)
