Here is a problem we encountered with NixOS:
The nix-channel we were on didn’t have the latest version of something we needed. This happened recently when my coworker upgraded to Postgres 9.5 from 9.4 but the PostGIS version in nixpkgs hadn’t been updated to a 9.5 compatible version.

Continuing from here, I have lists of tuples and I want to group them. Here I have a list of 4-tuples and I want to group the second tuple by the first. The fact that I need to do this probably represents some greater problem, but that is a story for another time
import shapeless._
import syntax.std.tuple._
import poly._
object GroupLists {
def group1TwoExtra[A,B,C,D](t : List[(A,B,C,D)]) : List[(A,List[B],C,D)] = {
val map = LinkedHashMap[A, LinkedHashSet[B]]()
val mapOther = scala.collection.mutable.Map[A,(C,D)]()
for (i <- t) {
val key = i.head
map(key) = map.lift(key).getOrElse(LinkedHashSet[B]()) + i.drop(1).head
mapOther += (key -> i.drop(2))
}
map.map(b => (b._1, b._2.toList) ++ mapOther(b._1)).toList
}
