I’m sure every seasoned .NET developer has been in the situation at one stage or another, probably in testing code, where they need to access a non-public setter of a property (or maybe a private member), and it can’t be mocked.  We all know the (somewhat scary) reflection trick to get at the said setter method and invoke it.   I just hit this problem today trying to mock some response messages from a Microsoft Dynamics XRM 2011 OrganizationService.  Thankfully F# gives us cool things like Quotations and s[...]

In this article we will discover how to emulate simple logic gates, and then build them up to form more complex circuits.  By the end of this 2-part article we will have created: - Half-bit adder - Full adder - n-bit ripple carry adder formed from full adders - 4:1 line decoder - 4:1 multiplexer - 1 bit ALU that supports addition, subtraction, AND and OR operations - n-bit ALU formed from 1 bit ALUs I have a great love of electronics, and everything covered in this article I have at some point built from[...]

Intro I have been using F# for a year and a half or so now for all sorts of things - general tools, scripts and utilities for work,  XNA games / graphics / AI simulations, some async layers for rx-driven silverlight applications  and so forth.  I'm still pretty new to the functional paradigm, which I have been embracing (with a great deal of mind melting, and destruction of my OOP and procedural shackles). One thing I struggled with initially was the subject of function composition, and its relationship to[...]

Back when I was in college, I took three different courses that dealt with subjects related to machine learning and data mining. Although I didn’t lose interest on those matters, my work has led me in a totally unrelated direction, so I haven’t exercised any of that knowledge in about eight years or so. A few weeks ago, I stumbled upon Stanford’s online class on Machine Learning and decided to enroll. I want to revive many of the things I have forgotten and try to put them into practice, as nowadays it’s[...]
