On Long Term Software Development - Bert Hubert's writings

Recently the Dutch Electoral Board (where I am also a very part time advisor) invited me to do a talk reflecting on their open source Abacus vote tabulation software. Much software is now provided as a service, and is typically deployed continuously (CD, continuous deployment), surrounded by enough automated testing (CI, continuous integration) that we can be reasonably sure that a new revision is likely to at least work to some extent.
