real type system. We're in the process of getting a public release together this term. I really need to get all my web content moved off Yale - I'll be happy to share the software / papers with anyone that's interested. My slides and papers should re

Just to clarify - I was the contact for Haskell.org but the email address was no longer being forwarded. I had assumed I had been removed as the contact but unfortunately only the technical contact had been changed. All was finally resolved with the help of Yale, where they resurrected the old

[Haskell-cafe] Computer Camp for kids 13 - 15 years old in Colorado featuring Functional Reactive Programming

2010-02-11 Thread John Peterson
Western State College in Colorado has a computer camp for kids aged 13 - 15. Although we don't use Haskell (it's Python on the inside) the underlying engine is Functional Reactive Programming. We use a 3-D game engine to explore more than just programming - we cover a lot of math and physics.

[Haskell-cafe] A bright future for Haskell

Especially if SPJ decides to grow a beard. Unfortunately Paul is now clean shaven so maybe Haskell is in trouble. http://blogs.microsoft.co.il/blogs/tamir/archive/2008/04/28/computer-languages-and-facial-hair-take-two.aspx John ___ Haskell-Cafe ma

[Haskell-cafe] map and list comprehensions

2006-02-05 Thread John Peterson
I think the point was that all syntax (like list comprehensions or pattern matching) in Haskell is tied directly to the Prelude. So [ f x ...] is ALWAYS using the Prelude definitions of things while "map" could be hidden and redefined. The inability to change the meaning of constructs expanded fr

Re: [Haskell-cafe] wxFruit examples

2005-01-25 Thread John Peterson
Hi there! The wxFruit effort was a senior project that focused pretty much exclusively on the paddleball game. It didn't really create any software that we intend to maintain and distribute. I have a couple of students working on a continuation of this but I don't expect to release anything for

Here are some comments regarding Haskell and the website. I think there are some things we can do to make it a little easier on people that enter haskell.org from outside the sheltered halls of academia. I think the comment about the organization of haskell.org is fairly accurate - we have been

Re: bugs from n+k patterns (was: Re: Preventing/handling space leaks)

2003-12-11 Thread John Peterson
The n+k pattern issue inspired endless debates on the Haskell committee and this feature was considered for removal in nearly every iteration of the Haskell report. We all agreed that n+k is extremely ad-hoc but that certain programs can be expressed slightly more elegantly using them. Unfortunat

If the spam storm gets too heavy on haskell-cafe we can switch to moderator approval as on the main Haskell list. We have the spam assassin available at haskell.org but I've been reluctant to turn it loose on the lists. Maybe the time has come ... John

Re: newtype | data

You can't recreate "newtype" with "data". There's a long discussion of this in the report: check section 4.2.3 http://haskell.org/onlinereport/decls.html#sect4.2.3 John ___ Haskell-Cafe mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman
