OOPSLA / Steele / Fortress

From: "andrew cooke" <andrew@...>

Date: Sat, 28 Oct 2006 14:43:04 -0300 (CLST)

Excellent talk.  Traits (see earlier comments on adapters or expanders or
whatever they were) reappear here.  Used, for example, to indicate
algebraic properties on types (associateive, commutative, etc).  Allows a
lot of functionality to be pushed into libraries.

Also extracts generators and reducers so that execution strategies can be
extracted.  Catamorphisms.  Looked like algebra followed by co-algebra.
Someone in questions just mentioning monads.

Lots of neat ideas here.  Haskell name-checked repeatedly.  "May regret
not having started with Haskell and [moving towards Fortran]".  Pattern
matching on the left seemed to be missing from fortress, which was
surprising given the emphasis on mathematical notation.

Really need to find the slides and go through this again.  Very
impressive. Not open source yet.

Oh, and type inference to some extent.

Fortress Loses Funding?

From: "andrew cooke" <andrew@...>

Sun just lost out to IBM and Cray in the latest DARPA HPC decision.  Does
that mean the end of Fortress?  The article below implies not, but if Sun
is out of the HPC competition, how likely is Fortress to succeed?

"The Programming Language Research Group (PLRG) at Sun Microsystems
Laboratories has just released the first reference implementation of the
Fortress programming language. The interpreter runs on the JVM and the
source code is available for download, by anyone, at:
http://fortress.sunsource.net "

(Thanks to Josh Simons, http://blogs.sun.com/simons/ for the heads-up;
