A good server design has no, or very few, single points of failure. One of the most common server component that fails, are disks. So data redundancy becomes essential to recoverability.

Running your TeamCity builds from PowerShell for any Git branch

Mon, 06 Feb 2012 19:46:55 GMT

I love TeamCity and use it since a while to automate my build/release processes. As human we should never do the work a machine can do, we have certainly better and more interesting things to do. The habit I saw in the different projects I worked for is to create new TeamCity builds for the branches you work on. It take quite some work to do, even with templates. So I came with another way of doing it. It is leverage Git, PowerShell and the possibility to run TeamCity builds by "Accessing Server by HTTP"

MVC Asynchronous Controller : The Basics

Tue, 17 Jan 2012 14:43:37 GMT

When I first saw the Asynchronous Controllers introduced in MVC 2, I couldn't wait to start playing around. I thought that it would be a really easy to get up and running with a simple example, but after searching online for a few working examples - pretty much all of them used an event based pattern that wasn't easy to understand. In this blog post I am going to run through a really simple example that will show you the basics of Asynchronous Controllers, and show you how easy they really are.

Simple explanation of the Repository pattern

Wed, 11 Jan 2012 15:36:50 GMT

One of my favorite design patterns is the 'repository pattern'. That's why I decided to dedicate a complete blog post to it. Using the repository pattern in your application can yield a lot of benefits, such as improved testability, easier ways to implement caching and transactions, avoidance of code duplication and it allows you to replace the data source easier (although that probably won't happen too often).

According to the Latest Tiobe Index, C++ is about to be dethroned by C#

Wed, 07 Dec 2011 16:56:35 GMT

Since the beginning of the TIOBE index back in 2001, the programming language C++ has been number 3 of the chart in a very consistent way. Perl, Visual Basic and PHP have been number 3 too, but these languages could keep this position only for a few months. Now C# is knocking on the door. It will certainly be a tough battle again. C# is Microsoft's most active and evolving programming language, whereas Microsoft recently announced to revive C++ in favor of... C#. We will see what will happen the next few months.
