In Memory of a Giant: Chris Seaton — It is with much sadness that the Ruby community learnt about the death of Chris Seaton last weekend. Chris worked for Shopify, but was well known as the founder of the TruffleRuby implementation while at Oracle, for being the first(?) Ruby doctor (his PhD thesis about Ruby is here), and generally being an interesting and helpful guy. Justin Searls has posted a tribute post of his own, as has Brandon Weaver.
