How to delete backlog items in TFS

I'm currently taking a course in software engineering, focusing on the agile development model. And in this course we are using Visual Studio Online. Visual Studio Online is an instance of Team Foundation Server (TFS) hosted by Microsoft, and is free for teams up to 5 people (with some restrictions).

And so at this course we are split into groups of 5 for the whole semester, avoiding spending ;-)

Anyways, one of the things i found non-intuitive with TFS was in the handling of backlog and work -items. Especially deleting items.
One would think that just right-clicking on the item would bring up the option, but thats not the case.

Not here

In order to delete a backlog item you need to doubble-click the item and set it's state to "removed":

Select 'remove' and it will move to trash

And once selected removed, you can still find the item if you do a query for removed items. The trash can model.

As a first time user i find TFS to be way more time consuming than it should need to.

Coke is IR transparent

Some time ago i made a blog post explaining how to remove the IR filter from a webcam in order to turn the webcam into a IR camera, or at least NIR (Near Infra Red).
Link here to the original post:

Now i recently came across something interesting. It turns out that Coke is actually IR transparent. It's rather mind boggeling how something so dark in color can look like water with a NIR camera.

Here are some photos:

In the background you can see the webcam feed, seeing the glass as transparrent

Side-scroller skateboard game with C# and XNA

This summer i was reading this book on game development, and even tho i did make a couple fun projects, i forgot to post them here.

But these past few hours i've been trying to clean up my messy folder structures and import all my repos to GitHub. And going thru all my stuff i found a few nice bits of code.

And this little skating game i made with C# and the XNA framework. The game is called ScrollinBackground.

Skate, avoid the obstacles and grind the rails.

Arrow keys to control the skater.

Space to jump.

Arrow up to grind rails.
