Optimizing Long Running Processes with EF6 – Postmortem
In: C#
4 Feb 2018One of the issues my workplace has been dealing with over the past several months has been intermittent slow performance of long running processes. In several cases it was impacting the entire company until the long running process had completed, it was doing pessimistic locking on reading data, causing deadlocks, and running really really slow. […]

MapReduce in C#
25 Jun 2011MapReduce is one of “those” buzz words that is going around at the moment. Mostly in part due to Google using it so successfully for their distributed indexing algorithms. So what is MapReduce? According to Wikipedia [http://en.wikipedia.org/wiki/MapReduce] So MapReduce is an amalgamation of two higher order functions taken from functional programming. Map and Reduce :. […]

Project Euler – Problem 2 (Haskell vs C#)
19 Jun 2011Problems with the .NET 3.5 implementation During implementation of the same algorithm from Haskell to (Functional) C#, I found that I hit quite a large snag with .NET (3.5) number types. A fibonacci sequence very quickly accumulates into integers larger than an Unsigned Long can contain, in which case you would have to move to […]
Lambda calculus can be summed up doing very much with very little, sacrificing only readability. Personally i’ve found the inability to peform recusion with a lambda expression to be a little pain in what should be an elegant solution. Lets take a factorial for instance, how to write that as a lambda expression? The fathers […]
Project Euler – Problem 4 (Haskell vs C#)
16 Jun 2011Learning a new programming language is perhaps one of the most rewarding experiences. You can learn about how another language performs a task, if it seems simpler how does this compare to your current language? Problem 4 from Project Euler goes something like the folowing. A palindromic number reads the same both ways. The largest […]
Power of Haskell
27 May 2011Learning haskell recently has really highlighted the power of the built in classes of haskell. Compare a function in haskell to captialize the first letter in a sentence, vs c#. Haskell 1 2 3 4 5 import Data.Char sentenceCase :: [Char] -> [Char] sentenceCase [] = [] sentenceCase (x:xs) = [toUpper x] ++ map […]

Compiling Resources using Nant
24 Sep 2010Including an embedded resource into your Nant script is not difficult at all. Simply add a resources tag and include the Full Namespace. Note that you will also need to include /Path/To/Resource/File.resx in the include if you don’t have the resource file under the root folder of your library. Here’s a working example. 1 2 […]
Using reflection to compare two objects
In: C#|Reflection
9 Jul 2010Here’s a helper that will allow you to compare 2 objects using reflection. Note: that this will also go through the objects base class and compare the base class fields and properties. I found it necessary to do this, however for speed you may want to add BindingFlags.DeclaredOnly to type.GetProperties() and type.GetFields() to limit the […]
Every now and again it’s necessary to resolve a dependency at runtime. When this happens you don’t really have much of a choice but to insert mock objects into your test fixtures IoC container. The following patterns allow me to specify 1 abstract base class and have all dependent unit tests inherit these stubs thus […]
