I'm trying to serve an image from Play, where the image originates from Gravatar. This code doesn't seem to work, but the URL is correct.

	import play.api._
	import play.api.mvc._
	import play.api.libs.ws.WS
	import play.api.libs.concurrent.Execution.Implicits._
	import java.io.File

	object Application extends Controller {

	def index(email: String) = Action {
	Async {

I'm trying to understand how to best deal with sending an async request to a web service

	def measures(user: User): List[Measure] = {
	val prefs = UserPreferences.findByUser(user) // get my prefs
	val request = generateRequest(prefs) // build up a WS request
	val promise = WS.url(exportEndpoint).post(request)
	promise.orTimeout(Nil, 100000).map { responseOrTimeout =>
	responseOrTimeout.fold(
	response => {
	val body = promise.value.get.body
	val lines = body.split("\n").map(_.split(","))
	lines.map {

The answer to Project Euler #11, using the Scala Actor library

	package euler

	import scala.actors.Actor
	import Actor._

	object Euler011 extends Actor {

	type Matrix = Seq[Seq[Int]]
	case class CalculateMaxRequest(matrix: Matrix, from: Actor)
	case class CalculateMaxReply(matrix: Matrix, max: Int)
