Next Two Weeks
Penguicon is a combination scifi convention and open source conference that's been running annually for 15 years. I'm a guest of honor at Penguicon 2017 (my schedule), as is MeFi's own Cory Doctorow (schedule) and Ada Palmer (schedule) whose work's been discussed on MetaFilter several times. Other speakers include MeFi's own John Scalzi. [more inside]
