The Discussion

• 

  Love the Holland shirt, Dan! Thanks

• 

  When are you guys going to post up the code for that laser graffiti wall you had a the PDC?  Just wondering...

• 

  That GPS plotting thing screams for somebody to create some sort of gigantic digital etch-a-sketch drawing. Guys, what are the odds of you people buying me a flight and tickets to Mix if I promise to drive around and plot a gigantic Nine Guy in the Nevada desert as a sort of scam promotional thing?

• 

  rofl. Thanks guys

   

  For anyone coming over, at my front door I have a gun, I mean a cannon, or a bazooka, all wired up using the sensor API. Pity the unannounced flower delivery guy or random CH9 stalker.

• 

  I love Holland, I need an excuse to visit, but it's hard with a 6-month old

• 

  Bas, agree on the etch-a-sketch, it was the first thing that popped into my mind.

   

  As for your odds of us getting you a ticket, hmm, probably low, the problem is we have plenty of other folks who are paying their own way and are asking us for permission to get inside the inflatable Channel 9 guy (which is pretty cool I must say)

  Re: destructors and finalizers:-

   

  No wonder there was so much confusion in the teaching of these concepts in the early days of .NET if the C# spec got it wrong! I remember so many tutorials where people were told all about finalizers "and this is how you can clean up like you do in a C++ destructor". NO NO NO!  The equivalent of a destructor is implementing IDisposable (and calling it in the appropriate place) - finalizers should never have been taught, even in intermediate programming books, let along beginners ones.  Interestinly Managed C++ as included in Visual Studio 2003 actually emboddied this error in that C++ destructors were implemented as finalizers, thus causing much confusion. The sucessor, C++/CLI, included in Visual Studio 2005 onwards changed it so that if a class has a destructor, in the CIL code it will actually implement IDisposable instead and calls to Dispose() are made in the same places they would be to the destructor of an unmanaged class.

   

  Re: Visual Basic 2010 feature cut.

   

  No iterators? What the heck guys, you had over 2 years!

   

  Re: HLSL

   

  It's not that hard. You know before HLSL you had to write what was essentially assembler code for the GPU. That was hard (although back then GPUs were a lot simpler - you couldn't have loops for example).

  Welcome back Brian!

• 

  Great show, thanks for the link guys.

• 

  @Chadk,

  Thank you, sir! It's so good to be back.

   

  @Pete,

  LOL!

  Hey PerfectPhase, the current ETA for the PDC laser graffiti is Febuary/March but we also will shortly be posted a simplified version called "Light Painting" of this that does far more of the "how / what" while Jeremiah's laser graffiti article will explain how he did a bunch of the more complex stuff.

   

  I also was afraid of posting 5 30 page long articles back to back.
