This got posted earlier and flagged, presumably by someone who didn't realise it was meant as humour (come on - "data.map.reduce" and you took it seriously?).

This got posted earlier and flagged, presumably by someone who didn't realise it was meant as humour (come on - "data.map.reduce" and you took it seriously?). This is actually quite clever satire (although tagging it as such makes it slightly less subtle :)). It spoofs the "Hadoop is trivial in R" article it links to (previously discussed at http://news.ycombinator.com/item?id=945196 http://news.ycombinator.com/item?id=945196) and gently knocks the breathless tone of some Ruby articles at the same time. There's even a dig at Guido in there. The following is on the money: "As a rule of thumb: a continuation is a block that has been captured inside a scope where a do is in effect, and cannot be passed to a proc, only to a lambda. It's really quite simple."
