This is the second in a series on the basics of functional programming using C#. My topic today is one I touched on last time, when I described the rights and privileges of a function as a first class citizen. I’m going to explore Higher-Order Functions this time. Higher-Order Functions are functions that themselves take or return functions. Meta-functions, if you like.
Read Full Post | Make a Comment ( 8 so far )Functional Programming is probably simpler than you think. It’s based on the idea that there is often very little distinction between programs an data. This post explores the basic techniques of functional programming and demonstrates their use in C#.

Olmo made a very worthwhile suggestion on the LINQ forums recently. His suggestion was for a new operator to be added to the C# language to allow us to do away with the following kind of pesky construct:
string x;
if(a != null && a.Address != null && a.Address.FirstLine != null)
x = a.Address.FirstLine;
instead [...]
Read Full Post | Make a Comment ( 9 so far )I should have brought the code up to date weeks back - but other things got in the way. Still - all the unit tests are in the green. And the code has been minimally converted over to the new .NET 3.5 framework. I say ‘minimally’ because with the introduction of beta 2 there is [...]
Read Full Post | Make a Comment ( 1 so far )I thought it was worth describing this configuration solution, since it was so neat, and easy, and had all of the benefits of text based configuration and strongly typed inline configuration.
Read Full Post | Make a Comment ( 2 so far )I was wondering the other day whether LINQ could be used with NMock easily. One problem with testing code that has not been written to work with unit tests is that if you test business logic, you often end up making multiple round-trips to the database for each test run. With a very large test [...]
Read Full Post | Make a Comment ( 7 so far )OWL defines two types of property: DatatypeProperty and ObjectProperty. An object property links instances from two Classes, just like a reference in .NET between two objects. In OWL you define it like this:
<owl:ObjectProperty rdf:ID=”isOnAlbum”> <rdfs:domain rdf:resource=”#Track”/> <rdfs:range rdf:resource=”#Album”/> </owl:ObjectProperty>
A DatatypeProperty is similar to a .NET property that stores some kind of primitive type like [...]
When I started implementing the SPARQL support in LINQ to RDF, I decided that I needed to implement as much of the standard query operators as possible. SPARQL is a very rich query language that bears a passing syntactical resemblance to SQL. It didn’t seem unreasonable to expect most of the operators of LINQ to [...]
