Here is a little video of me giving my Boo presentation at the code camp
This Saturday I headed out to the Surly Brewery in Brooklyn Center for D-Day. D-Day is the one day a year that you can buy bottles of Surly Darkness. Darkness is one of the best beers I’ve ever had and waiting a whole year just to get to taste it again certainly makes it extra special.

I am making available my boo presentation source code and slide deck in case anyone would like to take a look at it. It has many examples of the various features of boo. The way the presentation starts out is by quickly running through the boo slides and answering any preliminary questions as they come up then by going project by project down the list in the solution.
If you haven’t already taken a look at the Nov / Dec 2008 issue of CoDe magazine I would highly recommend it 😉 On my last gig at Magenic I had the pleasure of working for Rocky Lhotka, Sergey Barskiy and Nermin Dibek on CSLA Light. Along the way we managed to crank out an article for CoDe Magazine related to the work we were doing. Here is a link to the article online, Using CSLA .NET for Silverlight to Build Line-of-Business Applications.
I got a copy of this magazine at the last Twin Cities Code Camp and didn’t even know that I was a co-author of one of the articles in it! It wasn’t until the following monday that a coworker of mine pointed out to me that I was in the magazine and he only knew because he recognized my picture. That was pretty funny.
Now that I’m famous if anyone wants me to autograph their copy of CoDe magazine just let me know!
As an intellectual exercise I decided to write up 3 different ways to perform the same LINQ tasks. Actually I saw a comment on one of Don Box’s blog posts where someone asked why the Find and Exists methods weren’t static and I suddenly realized that they were, just with different names!
Assembly assemblies = AppDomain.CurrentDomain.GetAssemblies();
// Find an assembly that starts with System.
Func<Assembly, bool> startsWithSystem = a => a.FullName.StartsWith(“System”);
//List<T>.Exists equivalents for any enumerable
bool extensionAny = assemblies.Any(startsWithSystem);
bool explictAny = Enumerable.Any(assemblies, startsWithSystem);
bool linqAny = (from a in assemblies where startsWithSystem(a) select a).Any();
Debug.Assert(extensionAny == explictAny == linqAny == true);
// List<T>.Find equivalents for any enumerable
int extensionWhere = assemblies.Where(startsWithSystem).Count();
int explicitWhere = Enumerable.Where(assemblies, startsWithSystem).Count();
int linqWhere = (from a in assemblies where startsWithSystem(a) select a).Count();
Debug.Assert(extensionWhere == explicitWhere && extensionWhere == linqWhere);
I read something interesting on Scott Guthries blog about the release of Silverlight 2:
This is a bit surprising but a good move I think. Scott Guthrie and the ASP team have also been creating the ASP MVC framework under an open source license so it shouldn’t be too much of a shock to see the focus on interoperability with Silverlight. I do like this trend though, I feel like it’s important to focus on interoperability and support open source as much as possible.
Specification frameworks are a great way to enable a smooth approach to test driven development. A nice and simple specification framework called Specter has been created specifically for Boo, which includes a simple and elegant internal Specification DSL. If you’re curious to learn about specification frameworks, Boo or DSLs you should check out Specter for an elegant and useful example of all 3.
Here is a really great video of the step-by-step process:
