Continuations, futures, and whatnot - Thoughts on some asynchronous patterns

This sounds like one of those posts that's about to draw scientifically sound conclusions. It isn't. The other day I had a discussion about various ways to express asynchronisity (or asynchronousness, whatever spell checker upsetting word you prefer) in API designs. The answer might be shocking...

Why the **** all this Comega and Spec# stuff?

That's the paraphrased summary of a mail I received yesterday... :-). Let me give a very short answer: read this stuff, check out the C# 3.0 stuff which is due to be made public later this year at the PDC in LA and you'll get an aha erlebnis. And watch the Channel 9 video with Anders Hejlsberg on Programming...

Adventures in Comega - part 5 (database access)

Adventures in Comega - part 4 (Possibly-null values)

Introduction In the 4th episode of my "Adventures in Comega" series I'll be talking about a (smaller) language feature called "possibly-null values". As an example, consider a boolean value which has only two values (binary logic): true or false. However, what happens if you want to express that the...

Adventures in Comega - part 3 (Content classes)

Introduction One of the targets of the Comega language is to build a bridge between semi-structured data (read: XML) and objects. In future posts I'll describe how Comega fills the gap between relational data (read: SQL) and objects. But in this post, let's concrate on the former case. About DTD and...

Adventures in Comega - part 2 (Streams)

Introduction Streams in Cw are a way to create a kind of arrays (which consist of elements of a certain defined type) that are only created when these are needed (we call this lazy construction). As the matter in fact, streams are nothing more than autogenerated classes that are spit out by the compiler...
