Hey there, some of the features you listed in the GeoServer section have been in the stable release for a few months already: sql views, styling SLD in data units and virtual services.

The things that will come up next are time/elevation support, and the georeferencing process, which is really just a WPS process (the GUI you saw was a GeoExt client built on top of it)

Cheers
Andrea

Comment on Scala’s Numeric type class (Pt. 2) by Michael E. Cotterell

Erik,
I didn’t know about that top-level import for Numeric implicits. That’s actually pretty cool. Anything that lets me write less code when dealing with generic type parameters is always nice!

Suggestion: rewrite NumericRange in terms of whatever you have presently, taking the (numerous) open bugs against it into account. It will either uncover weaknesses in the design, or if not, give you that much more weight to get into the standard lib.

For extra credit, prove that your @specialized NumericRange is as fast with Ints as the standard, Int-specific Range.

Joseph,

Thanks for your kind words.

I am sure that the Scala team wants to improve Numeric. The question is how much time they will have for this relative to the other improvements they are working on.

I will keep posting as I learn more.

Michael,

I agree this is nice, although in 2.9 you can actually do a top-level import to get this (import Numeric.Implicits._)

Initially I was trying to be more explicit to help people see what was happening. But yeah, for everyday use you really want to be able to use infix operators.

I like importing the Numeric view in the function body. This enables the implicitly defined numeric operations in Numeric. For example:

def square[A](a: A)(implicit num: Numeric[A]) = {
import num._
a * a
}

def square[A: Numeric](a: A) = {
val num = implicitly[Numeric[A]]
import num._
a * a
}

very nice post

hopefully you will get the proper answer and end up helping scala numerics to improve, which sounds great

imho, as a scala newbe, I really enjoy this quite in depth kind of post which actually are pretty easy to understand, while still widening one knowledge.

Thanks a lot and keep us updated !

The syntax of the double-implicit form is Sooooo nice though, I’ve taken to calling it the “pimp-my-typeclass” pattern.

I’d be surprised if it doesn’t get a special optimisation in some future release of scala.
