In the first part of the series I waked through how I came upon Metaprogramming and IronPython in particular. I also showed some simple examples with it. In this post I'll be going through creating a Deserializer with IronPython and hopefully learning something along the way. In case you missed part 1 it's available here Metaprogramming with IronPython - Part 1 Introducing our interface The interface we'll be using in this test is the IDeserializer interface from Seekwell using System.Collections.[...]

While writing Seekwell there were several ideas that came and went trying to optimize the deserialization from IDataReader to IEnumerable<T>. The minimum viable product was to simply use reflection. That of course was slow so we cached as much of the reflection as we could. What if we created a deserializer that would write code to do the deserialization for a given type? The .net framework has several ways of essentially compiling code at runtime. Microsoft.CSharp.CSharpCodeProvider and System.Reflec[...]

We have years worth of historical queue data in a Microsoft Sql database and the same tables that contain this historical data also keep track of pending or currently active work. Here's a highly simplified visual example. TypeSubtypeStatusParameters ExportEmailComplete"From: noreply@foo.com, To: someone@bar.com" ImportExcelActive"FilePath: c:\import.xls" ImportWebPending"Url: http://google.com" This structure leaves us with several issues: Contention: To handle volume we have many windows serv[...]

You may notice that I've changed my blog again. This time I've renounced Blogger completely in favor of Ghost. You may also notice that I have it running on Azure now which means that I actually have control of all the source code for the site. A major win compared to Blogger where everything is a widget. That's probably great for non devs, but it's much easier for me to write a handlebars template with bootstrap than it is to try and hack a prebuilt widget or theme. I'm hopeful that the formatting on[...]

That’s the title of the presentation I’ll be giving at CloudDevelop 2014, on October 17th, in Columbus, Ohio. If you read my blog at all then you’re probably interested in where software development will be headed five years in the future. Two things I recommend that you study are proving systems and homomorphic encryption. I’ve written [...]
