Parallelizing activities In my previous post I mentioned some of the shortcomings with Amazon SimpleWorkflow (SWF) which drove me to create an extension library on top of the standard .Net SDK to make it easier to model workflows and business processes using SWF. In this series …

This is a F# implementation of the fast algorithm to count the number of inversions in an array, outlined in the Algorithms : Design and Analysis Part 1 course on Coursera.
Here’s a simple F# implementation of the merge sort algorithm (using mutable arrays) outlined in the Algorithms : Design and Analysis Part 1 course on Coursera. So refreshing to be writing simple sorting algorithms years after university, still fun!
Amazon SimpleWorkflow (abbreviated to SWF from here on) is a workflow service provided by Amazon which allows you to model business processes as workflows using a task based programming model. The service provides reliable task dispatch and state management so that you can focus on developing ‘workers’ to perform the tasks that are required to …

.Net 4.5 introduced a handy little new method Comparer<T>.Create to aid the creation of bespoke comparers, which is great because it means that you don’t have to define a new Comparer class when it is going to be needed once. In case you’re wondering, it’s still not possible to define anonymous implementation of interfaces in …

Just a quick note to say that I have made some minor changes to DynamoDb.SQL to: Add support for specifying the ScanIndexForward option(see DynamoDB API doc here for detail) in a Query operation using an optional “ORDER” clause Fixed a bug where when querying using the extension methods on the DynamoDBContext class, the LIMIT clause …
Just a quick note to say that I have updated the JSON serializers benchmark to use the latest Nuget versions of ServiceStack.Text, Json.Net and JsonFX. I have also included the JSON and BSON serializers from the MongoDB C# Driver in the test, and since BSON is a binary format I have included protobuf-net as a …
