Last week I was playing with a photomosaic composer toy project and needed a simple search by image engine. By search by image I mean searching a database for an image similar to a given one. In this tutorial I will show you how you can implement this functionality –with some obvious limitations– in an [...]
I’ve seen things you people wouldn’t believe. Source code copied and pasted several times. I watched user interface events glitter in the dark down to the business logic. All those lines will be lost in time… like structs on the stack. Time to die.
The second project I recently completed in F# is a completely different animal. While the first one is a pet project I’ve put together in my spare time (with no deadline at all), this one has been a full-time work for my company (for this reason I cannot disclose some details or share source code). [...]
I’ve been playing with F# on and off for about one year, but only recently I was able to complete a few “real world” projects. I was so impressed that I decided to share my experience. In this two-part series I will talk about two very different projects to give you an idea of how [...]
in TDD you are often confronted with the question “should I restrict my unit test to public methods or include private ones as well?”. There isn’t a widely accepted consensus and there are many articles around on the subject. I’ve been thinking about it recently and this is my take on it. A class’ public [...]
It may be obvious for most of you, but it took a while to my caveman brain to realize this, so I figured I could post it for other cavemen. You (we) have got an excuse though: the short release cycle of Silverlight means that most stackoverflow questions and blog posts on the subject are [...]
UPDATE: Xavier Decoster already wrote a nice article on this topic some time ago. Please check it out! (Note to self: improve google skills) First, let me say that I’ll take the long route, so if you are already familiar with dynamic typing in C# you can probably jump straight to the last section. Otherwise [...]
After playing with some Silverlight beta bits, going back to RTM, etc. I could not compile F# projects for Silverlight 4 anymore. Even after reinstalling everything in [what I think is] the right sequence I was still getting this error: F# runtime for Silverlight version v4.0 is not installed. Please go to http://go.microsoft.com/fwlink/?LinkId=177463 to download [...]
Windows Phone 7 like every other phone OS turns off the screen after a period of inactivity. This is not a problem most of the time because any user activity (namely finger interactions on the screen) resets the countdown, so if you are using an application the screen saver will not get in the way. [...]
Pinch zooming is one of those things that look incredibly simple until you actually try to implement them. At that point you realize it hides quite a number of intricacies that make it hard to get it right. If you tried to implement pinch zooming in Silverlight for Windows Phone 7 you probably know what [...]
