A few months back, when I started working on the .Net Micro Framework “Dare to Dream Different” contest, I started thinking about Netbooks.  The longest time before that I always wanted the biggest and fastest laptop I could get.  But the thinking changed when I thought about the fact if I won the contest I would need to pack up my project and a laptop… and being the photo geek that I am I would want at least one of my cameras with me as well.  Now stuffing a 15....

While not as bad as calculating PI in BF this LINQ statement is pretty impressive. Being able to define a full ray tracer in a single, complex, fuctional, recursive statement is very interesting. Ray Tracing in LINQ

  In the sprit of playing with a string chop question on stackoverflow… I somehow got myself into the middle of some fun code profiling.  So this is a report of the code and results. (this is related to a previous most I made as well http://hackersbasement.com/?p=134) Charted Short String Results Person Version Run 1 Run 2 Run 3 Str SB J Str SB J ... [More]

In coming across this question on StackOverflow I  inspired to write my own version for the question.  I started to think about using a List<string> but decided to create sized array up front.  My version was taking longer than I hoped (mainly because I kept refreshing the site) but I did create a version that used string.Join and Array.Copy.  Wanting to compare the speed differences between a few of the answers I put together this little test of code. (as a side note... [More]

Two chucks of code... both do the same thing. Why is the version with the goto so much worse? I would even debate that i Dim password1 As String While True Console.WriteLine("Enter Password: ") password1 = ReadHiddenString() If String.IsNullOrEmpty(password1) Then Continue While Console.WriteLine("Reenter Password: ") Dim password2 As String = ReadHiddenString() If String.IsNullOrEmpty(password2) Then Continue While If password1 password2 Then Continue While...

Two chucks of code... both do the same thing. Why is the version with the goto so much worse? I would even debate that it is clearner.

After playing a little with Inversion of Control Containers... and being annoyed by the backing of a Hash Table or Dictionary, I decided to use some generic magic. And just for giggles I tossed in some .Net 3.5 Extension method love. Oh, as a warning... I build this on VS2010 Beta 1 so the Range object's constructor has optional parameters. Please feel free to leave questions and comments. -Thanks, Matt using System; using System.Collections.Generic; using System.Linq; using System.Collect... [More]

I decided to play around with VS2010 Beta 1 this weekend. While talking with one of my dev friends, I was asked what I thought about the Parallel extensions. Having not used them yet I figured I'd give them a go... [More]

After running across a "code golf" question this afternoon on stack overFlow I answered with a short answer... using (var inFs = File.OpenText(args[0])) using (var outfs = File.AppendText(args[1])) { outfs.Write("<table border="0">"); while (!inFs.EndOfStream) outfs.Write("<tbody><tr><td>" + string.Join("</td><td>", inFs.ReadLine().Split(',')) + "</td></tr>"); ...

Okay... those guys over at MSR (Microsoft Research) as just INSANE. Photosynth is too cool. Here is a synth of a scupture I own. Dragon Egg Savannah Clipper ... Enjoy, Matt
