A pattern a week...

I know some design patters, and I have used some, but I haven't studied them properly, so now I am thinking I will pick up all the books I have and study 1 pattern per week. Lets see how it goes.

Shuffle a deck of cards

hmm I never thought of this before, if I had to write a program to shuffle a deck of cards, how would I do that?

Fisher-Yates shuffle

PDF Is Now ISO 32000

Check out : iso_ballot_for_pdf_17_passed

So what does that mean? what is this ISO 32000 standard?

Anyway, here's how you can create your own PDF

• PDFCreator This software installs a printer which can print any document as a PDF.
• 2007 Microsoft Office Add-in After installing this, you will be able to save all Office 2007 documents as PDF.

Forget Vista Animation

Check out XGL it looks way to advance than what vista can offer.

Time difference logger

Did you ever have to log time taken by some chunk of code? I hate writing log statements every where to get time difference - so I came up with this :

   1: using System;

   2: using System.Collections.Generic;

   3: using System.Linq;

   4: using System.Text;

   5: using System.Threading;

   6:  

   7: namespace TimeLogger

   8: {

   9:     class Program

  10:     {

  11:         static void Main(string[] args)

  12:         {

  13:             using (TimeLogger tl = new TimeLogger("sleeper"))

  14:             {

  15:                 Thread.Sleep(3000);

  16:             }

  17:         }

  18:     }

  19: }

   1: using System;

   2: using System.Collections.Generic;

   3: using System.Linq;

   4: using System.Text;

   5: using System.Diagnostics;

   6:  

   7: namespace TimeLogger

   8: {

   9:     public sealed class TimeLogger:IDisposable

  10:     {

  11:         private Stopwatch sw;

  12:         private string codeDescription = string.Empty;

  13:         public TimeLogger()

  14:         {

  15:             this.sw = Stopwatch.StartNew();

  16:         }

  17:         public TimeLogger(string codeDescription)

  18:         {

  19:             this.codeDescription = codeDescription;

  20:             this.sw = Stopwatch.StartNew();

  21:         }

  22:  

  23:         void IDisposable.Dispose()

  24:         {

  25:             sw.Stop();

  26:             if(string.IsNullOrEmpty(codeDescription))

  27:                 Console.WriteLine("Time taken by = {0} ms", sw.ElapsedMilliseconds);

  28:             Console.WriteLine("Time taken by {0} = {1} ms",codeDescription, sw.ElapsedMilliseconds);

  29:         }

  30:     }

  31: }

What do you think?

VS 2008 and .net 3.5 is out

Multithreading is a pain

synchronizing pieces of code is a lot lot harder than i thought... basically this is the first time i am working on multithreading stuff. I added a lot of variables just to keep track of the state... then my manager gave me a solution to have a seperate entity which will co-ordinate and supervise all the threads... hmmm lets see how that one goes.

Make Vista go ....zzzZZZ

Technorati Tags: Vista, shutdown, sleep, rundll32, power options

Looks like you cannot make Vista machine go to sleep using the shutdown command, but there is this pill available :
