Open source warfare, Matisyahu leaves Lubavitch, RPG studies

• Following my mention yesterday of the Atlantic piece on primary loyalties and current warfare, also worth mentioning is Robert Charette's article 'Open-Source Warfare' in IEEE Spectrum. (I'm not really that fond of the term 'Open-Source Warfare', but it seems like an adequate descriptor.) Mentioned in the article are John Robb, originator of the term, as well as Eric Raymond, open source software theorist.
