Daikon on Windows 7

Make sure you set the Classpath (not path) environment variable to the following:

.;C:\Program Files\Java\jdk1.7.0_17\lib\*;D:\C Drive\Desktop\Daikon\daikon\daikon.jar;

or

.;C:\Program Files\Java\jdk1.7.0_17\lib\*;D:\C Drive\Desktop\Daikon\daikon\daikon.jar

Command to compile

cd /d "D:\C Drive\Desktop\Daikon\daikon\examples\java-examples\StackAr"

javac -g -source 5 -target 5 DataStructures/*.java

Method A. Combine the Intrumentor and invariant detector (sometimes it does not work)

java daikon.Chicory --daikon DataStructures.StackArTester

Method B. Split the Intrumentor and invariant detector

java daikon.Chicory  DataStructures.StackArTester

java daikon.Daikon StackArTester.dtrace.gz

Highlighting the different between Latex Documents in Windows 7 using Latexdiff

Wondering is there a way how to make a diff for latex files or documents?
The answer is a definite Yes! You need latexdiff which comes with Miktex

Following is a step by step guide for installing it in Windows 7:
Prerequisite
You need to install:

1. Miktex (http://miktex.org/2.9/setup)
2. Perl (can use Strawberry Perl: http://strawberryperl.com/releases.html)

Step By Step Guide
Assume Miktex and Perl Interpreter are installed, and Miktex is installed in "C:\Program Files (x86)\MiKTeX 2.9\" (Other directory is fine, just adapt accordingly)

1. Go to  "C:\Program Files (x86)\MiKTeX 2.9\scripts\latexdiff\"
2. Create a a new folder "perl" in "C:\Program Files (x86)\MiKTeX 2.9\scripts\latexdiff\"
3. Copy all files in "C:\Program Files (x86)\MiKTeX 2.9\scripts\latexdiff\" to new folder "C:\Program Files (x86)\MiKTeX 2.9\scripts\latexdiff\perl"
4. Rename all files (without extension) in "C:\Program Files (x86)\MiKTeX 2.9\scripts\latexdiff\perl", with an extension .ple.g., latexdiff to latexdiff.pl
5. Add "C:\Program Files (x86)\MiKTeX 2.9\scripts\latexdiff\perl" to the PATH environment (if you are not sure how to do so, see here)
6. Open Command Prompt, and type in
   latexdiff.pl --flatten PreviousFile CurrentFile> diffe.g., latexdiff.pl --flatten "C:\old.tex" "C:\new.tex" > "C:\Diff.tex"

Sample
Below is  a sample for Diff.tex, where you can see what's old (cross out, red color) and new (underline, blue color) easily, pretty cool right :)

ISynchronizeInvoke implementation example

Put the following code for classes you want to implement ISynchronizeInvoke should do the job

        private readonly object _sync= new object();

        public IAsyncResult BeginInvoke(Delegate method, object[] args)
        {
            var result = new SimpleAsyncResult();

            ThreadPool.QueueUserWorkItem(
                delegate
            {

                result.AsyncWaitHandle = new ManualResetEvent(false);
                try
                {
                    result.AsyncState = Invoke(method, args);
                }
                catch (Exception exception)
                {
                    Debug.WriteLine(exception.Message);
                    Debug.WriteLine(exception.StackTrace);
                    result.Exception = exception;
                }
                result.IsCompleted = true;
            });


            return result;
        }


        public object EndInvoke(IAsyncResult result)
        {
            if (!result.IsCompleted)
            {
                result.AsyncWaitHandle.WaitOne();
            }


            return result.AsyncState;
        }


        public object Invoke(Delegate method, object[] args)
        {
            lock (_sync)
            {
                return method.DynamicInvoke(args);
            }
        }


        public bool InvokeRequired
        {
            get { return true; }
        }
        public class SimpleAsyncResult : IAsyncResult
        {
            private object _state;


            public bool IsCompleted { get; set; }


            public WaitHandle AsyncWaitHandle { get; internal set; }


            public object AsyncState
            {
                get
                {
                    if (Exception != null)
                    {
                        throw Exception;
                    }
                    return _state;
                }
                internal set { _state = value; }
            }

            public bool CompletedSynchronously
            {
                get { return IsCompleted; }
            }


            internal Exception Exception { get; set; }

        }
