I began typing a response but after some thought, I realize that the answer to your dilemma is complicated by the fact that you may seek 2 positive outcomes rather than 1 for your problem. Here's a potential solution: "Work-Productive" Saturday computer/coding related and results in a viable product + full-time involvement by other participating individuals = hackathon/co-founder meetup for projects (perhaps non-profit ones would circumvent IP/competitive issues?) "Personal-Productive" Sunday not drinking/pub related + can result in friendships/relationships = any activity that you truly enjoy/want to try out that is NOT computer-related and NOT solitary by default (e.g. going to the gym to lift weights, while is a great activity, may not be recommended for this purpose because it's hard to chat people up when they are concentrating on their new max reps. Whereas a team sport that requires communication may be more amenable.)
