We’re joined by C J Silverio, aka ceejbot on Twitter, aka 2nd hire and former CTO at npm Inc. We talk with Ceej about her recent JS Conf EU talk titled “The Economies of Open Source” where she laid our her concerns with the JavaScript language commons being owned by venture capitalists. Currently the JavaScript language commons is controlled by the npm registery, and as you may know, npm is a VC backed for profit start up. Of course we also talk with Ceej about the bomb she dropped, Entropic, at the end of that talk — a federated package registry for JavaScript C J hopes will unseat npm and free the JavaScript language commons.
