Over this past week at PDC I was lucky enough to see some fantastic sessions and spend time with members of the F# and greater Visual Studio language teams.  Naturally, these experiences have left me both floored and swimming in new ideas.  This edition of Discoveries This Week includes both the very best of what I saw at PDC 2009 and ...

F# events are popping up all over the place and so I’ve included a separate section for them today.  As far as posts go I’ve stumbled across immutable queue and range libraries,  a post on the underlying implementation of discriminated unions, using the reactive framework and finally, a Microsoft research project: F7 Refinement ...

I’m back from my three week vacation and am just about buried in fascinating functional programming links.  I’ve managed to get through most of them and have selected the best of these for this very special welcome back edition of Discoveries This Week.   CUFP (Commercial Users of Functional Programming) 2009 Videos “Functional ...

With the start of our F# User’s Group this next Monday and New England Code Camp 11 last weekend, things have been extremely busy this past week.  Meanwhile, the F# sociocosm is growing at a rapid pace.  This week we have a talk by Don Syme, a look at F# quotations, and finally, some discussion on Seq.unfold.   Chris Bowen’s Post, ...

This week we have MapReduce, WebTools and yet another F# to C# language comparison.  I spent yesterday at a seminar led by Michael de la Maza.  He, Talbot Crowell and I will soon be starting a F# user’s group in Boston, Massachusetts.  I’m interested in any comments you might have.  Please feel free to send me an email if you ...

This week I have a very diverse set of topics:  First, using the functional programming concept of folds in C# to reimplement much of LINQ.  Then a bit of reflection on F# Grammar Parsers.  Finally, some community discussion on real world F# applications.   Blog – Matthew Podwysocki’s Functional C#, Fun With Folds In this ...

This week we have practical examples of Lazy Evaluation with Memoization, an interview with Don Syme and a discussion on the Visitor Pattern’s place in F#.  Also, any comments on the new title for my weekly posting would be appreciated.   Forum – Memoization and Lazy Evaluation in F# on HubFS In this thread brianmcm (Brian ...

Another very exciting week.  I’ve barely had time to catch my breath. Meanwhile I’ve decided to take my weekly roundup post consistently in the direction of functional programming in the Microsoft universe for the foreseeable future.  This will be with a heavy slant towards software engineering and, of course, F#.    Post: ...

This week’s theme is functional programming.  Included are discussions on Software Transactional Memory, Functional Architecture and the impact of the CLR on functional Programming in .NET.   Blog: Brandon Werner’s Software Transactional Memory: Debunked! In starting with a title that is decidedly sensationalistic, Brandon effectively ...

It’s been a very exciting week.  I actually had more things to post than time would allow me to write about.  I’ll have to save them for next time.   Blog: Daniel Spiewak’s What is Hindley-Milner? (and why is it cool?) Hindley-Milner is the algorithm all these fancy programming languages like F# and Haskell for type ...
