OSNews covered the One night in Prio article, and now a new version of its umbrella project, Arcan, has been released (which only happens two or three times a year). The actual details are covered in the release post.
So, what is Arcan?
Arcan is a powerful development framework for creating virtually anything between user interfaces for specialised embedded applications all the way to full-blown standalone desktop environments.
At its heart lies a robust and portable multimedia engine, with a well-tested and well-documented interface, programmable in Lua. At every step of the way, the underlying development emphasises security, performance and debugability guided by a principle of least surprise in terms of API design.
