Following my recent webinar with SharpCrafters on how to setup pseudo real-time performance monitoring using Aspect Oriented Programming and Amazon CloudWatch, I’d like to say thanks to the guys for having me, it was a great fun For anyone interested, the source code is available at: http://aop-demo.s3.amazonaws.com/RTPerfMonDemo.zip If you want to run the demo console …

I love using F#’s Record and Discriminated Union types, they work nicely with pattern matching inside your F# code and can often alleviate some of the ceremony involved around creating and using a complex object hierarchy. However, on the odd occasion when you need to serialize them into JSON/XML/Binary format, it might not be immediately …

I will be doing a webinar with the good folks of PostSharp on the 22nd March to talk about the use of AOP and AWS CloudWatch as a pseudo real-time performance monitoring tool (see high-level overview here). It’s a free webinar, it runs from 22nd March 3PM – 4PM GMT, the registration link is here. …
Note: don’t forget to check out the Benchmarks page to see the latest round up of binary and JSON serializers. Since my last round of benchmarks on binary serializers, there’s a new player in town – MessageShark, which at the time of this writing does not support serialization of fields, but offers comparable speed …
For illustration purposes only, here’s how you can implement the QuickSort algorithm in a few lines of code: Note that I’ve not made the list generic to avoid complications and performance overheads associated with dealing with generics. Even then, my 5-line implementation pales in comparison with the built-in sort function: This just goes to show …

This is something I’ve mentioned in my recent AOP talks, and I think it’s worthy of a wider audience as it can be very useful to anyone who’s obsessed with performance as I am. At iwi, we take performance very seriously and are always looking to improve the performance of our applications. In order for …

C# By default, arithmetic operations and conversions in C# execute in an unchecked context, you can use the checked keyword to switch a block of code to the checked context so that any arithmetic overflow that occurs in that block of code will cause the OverflowException to be thrown: However, the scope of the checked …
In C#, you can use the object/collection initialization syntax like this: The F# equivalent of object initialization is done like this: As for collection initialization, you have a far more diverse range of tools available to you, for example: You can also create slices of an existing array: You can even add your own multi-dimensional …

If you’re reading this post, you probably know about F#’s Units of Measure already, it’s very useful when working with real-world units and adds extra safety to code that needs to work with and convert from one unit to another. Here’s a quick snippet that shows you how to define and use units-of-measure: This code …
