Generate a X509 Certificate for testing purposes
Small script to generate a X509 certificate for testing purposes. In my case, for generating signed PDF documents. This will write the certificate and it's key out into a Pkcs 12 store. It relies on the BouncyCastle library (version 1.7 worked fine).

The Haskell const function
The const function is simple, but you can use it to make your code more legible. In this example we convert a unary function to a function of arity 2 (that ignores the second argument). Also by using the flip function from Haskell (which is equally easy to define) you can ignore the first argument.

Continuation-Passing Mnemonics
Continuations provide a means whereby heap space can be traded for stack depth (heap space being generally more plentiful than stack depth). They are especially useful where tail recursion is not possible. Here are a couple of simple continuation examples that can be extended to cover more complex scenarios.

ObservableObject
The ObservableObject type implements the INotifyPropertyChanged interface used in WPF and Silverlight to notify on changes to properties that are bound to a control. Specify property names type safely using F# Quotations, i.e. <@ this.PropertyName @> when invoking the NotifyPropertyChanged method. If you are following the MVVM pattern then your View Model class can inherit from the ObservableObject type.
