Binomial probabilities
Simple function for commute binomial probabilities. For quick summary about binomial distribution: 1.) There are a fixed number of trials (n). 2.) Each trial has two possible outcomes: success of failure 3.) The probability of success (p) is the same for each trial. 4.) The trials are independent, meaning the outcome of one trial doesn't influence that of any other.

version 1 is http://fssnip.net/62. This new version support convert from any existing function to a converter function by using composition and pipeline. The convert function is to make the function signature agree to the IValueConverter interface. You can add new functions in the FunctionLibrary module and reuse the class definition to reduce the coding effort. The first sample is to show how to make the converter pipeline work, the second one is a debugger converter used to debug the data binding problem.

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.

Posted: 3 years ago by Neil CarrierImplementing active objects with a MailboxProcessor
Mailbox processors can easily be used to implement active objects. This example shows how to do that with a reusable wrapper type and minimal boilerplate code in the actual class definitions. Supports both asynchronous calls and synchronous calls. For the latter case, exceptions are automatically propagated back to the caller.
