Recently, upon the recommendations of a few people, I picked up a copy of the book “Beautiful Architecture: Leading Thinkers Reveal the Hidden Beauty in Softwareâ€�.  This book is a great read and includes essays from some of the top minds in software today.  Some of the topics covered a...

In the past I’ve extensively talked about creating monads, but not as much more around them in terms of why you might use them and what problems they are trying to solve.  Since that time, I’ve been challenged by others to actually prove not only that it can be understood by everyone, but t...

Lately I've been getting back to basics with regards to recursion.  This is a basic and essential skill, especially in the functional programming world.  Today's dive will be into immutable lists and recursion.  I'll do my best to provide the F# and C# equivalent to each call.  T...

Lately, I've been doing some functional C# in both user groups and on this blog.  As the C# language has evolved it has definitely taken some functional programming aspects, such as high order functions, extension methods, LINQ and so on.  But with that, there is a cost.  Functional p...

As I've covered earlier, I'm very interested in the unit testing and behavior testing story in F# and functional programming.  And as I've indicated earlier, I'm pretty fascinated by Domain Specific Languages (DSLs) as well in this regard.  In the past, I've posted about some of the intere...

It was often asked during some of my presentations on F# and Functional C# about the future direction of C# and where I think it's going.  Last night I was pinged about this with my F# talk at the Philly ALT.NET meeting.  The question was asked, why bother learning F#, when eventually I'll...

This past weekend was the Northern Virginia Code Camp in Reston, Virginia.  There was a pretty good turnout for my two sessions which were the first two of the day.  Unfortunately, I could not stay the whole day to attend some of the other sessions including fellow DC ALT.NET'er John Moral...

In one of my previous posts about Command-Query Separation (CQS) and side effecting functions being code smells, it was pointed out to me again about immutable builders.  For the most part, this has been one area of CQS that I've been willing to let break.  I've been following Martin Fowle...

After talking with Greg Young for a little this morning, I realized I missed a few points that I think need to be covered as well when it comes to side effecting functions are code smells.  In the previous post, I talked about side effect free functions and Design by Contract (DbC) features in ...

I know the title might catch a few people off guard, but let me explain.  Side effecting functions, for the most part, are code smells.  This is a very important concept in Domain Driven Design (DDD) that's often overlooked.  For those who are deep in DDD, this should sound rather fam...
