There is a very nice Graph Visualization Software from AT&T called Graphviz. You can have a look at the types of graphs that can be generated using it. It consists of a few tool named "dot", "neato" etc... It is realeased under a open-source type of license. As a result of which good a number of tools, library, language bindings, third-party apps have been developed around it. It has been ported to window by Ood Tsen as a co component with support for various languages like c++, vb, asp and perl. It is called WinGraphviz

Here is the code that is used for generating it

#include <atlbase.h>
#include <iostream.h>
#include "WinGraphviz.h"

const IID IID_IDOT = {0xA1080582,0xD33F,0x486E,{0xBD,0x5F,0x58,0x19,0x89,0xA3,0xC7,0xE9}};     
const CLSID CLSID_DOT = {0x55811839,0x47B0,0x4854,{0x81,0xB5,0x0A,0x00,0x31,0xB8,0xAC,0xEC}};

int main(int argc, char* argv[])
{
 USES_CONVERSION;
 HRESULT hr;
 IDOT * pIDOT;
 unsigned short* result;
 IBinaryImage *img;

 hr = CoInitialize(NULL);
 if (FAILED(hr)) {
  cout << "CoInitialize Failed: " << hr << "\n\n";
  exit(1);
 }
  
 hr = CoCreateInstance (CLSID_DOT, NULL, CLSCTX_ALL, 
  IID_IDOT, (void**)&pIDOT);
 if (FAILED(hr)) {
   cout << "CoCreateInstance Failed: " << hr << "\n\n";
   exit(1);
 }
 
 hr = pIDOT->ToPNG(A2BSTR("digraph G {      A -> B; E -> B; E -> D; D -> C;    B -> D; D -> E; F -> D; G -> A;    D -> A; B -> G; H -> C; G -> H;    C -> A; B -> H; E -> H; H -> A; }"),
   &img);
   
 img->Save(A2BSTR("Hi.png"),(VARIANT_BOOL*)&result);
 
 if (FAILED(hr)) {
   cout << "ToSvg Failed: " << hr << "\n\n";
   exit(1);
 }

 CoUninitialize();
 return 0;
};

I have a dream; To create stuffs that are used by millions and millions of people, like Yahoo, Google and Windows, not neccessarily making billions of dollars. Making money is not a big priority for me, but making stuffs used by millions of people is a dream of me. I don't know whether I will ever succssed in realizing my dream or not. My e-books link collection on geocities and its further porting to blogger is just a consequence of it.

By looking at nice softwares (both small and big), an internal force within me bugs me to make such nice stuffs. I agree making such stuffs single handedly without a team is a day-dream. But still, I don't know why, I always feels that I can do that, I have enough capabilities, but I am not utilizing to its fullest extend because of "N" numbers of reasons. I have made few small goddies (These are too small to be called as a software, little bigger to be called as program). Some of them are incomplete or partial or not upto my visualized system.

Using my blog as a medium, I am interested to extends my ideas to some distant soul who might find usefull to it, might contribute something make it more usefull or might enable me to achieve my dream mentioned above.

I have always a plan to make a unix like shell in windows. It can be easily made in console mode. But I have laways interested it to be in GUI mode, something similar to matlab or ssh console. I have a plan to add basic functionalities of the language and extend it further to have similar capability as matlab (like that of octave but not using gnuplot for plotting but with own plotting library).

I have made a small step into it by making a gui using MFC. I have implemented only 3 systems command till now i.e. pwd, help, and ls. I will be adding much ore functionalities in near future. I am also learning python to evaluate possibilities to using it to simplify my design process. Let's see how much I can progress to achive a complete unix like shell.

It is called as "Patel Shell", in the name of the hall of residence I am currently in at IIT Kharagpur, India.

Hi friends,

I have recently designed a new blogger template. You can have a look at it at http://indiabloglist.blogspot.com/

you can use the template if you like. I have made a zip file and uploaded to geocities for convinience. It is at http://www.geocities.com/x_scn/template.zip

To use it just download it, unzip it and copy and paste the content of the text file in your template. Make sure that you have backed-up your previous template in ur computer. It is highly advisable because it is the only solution in case you have changed your mind to move-back to your old template.

This can be considered as "something-like" beta version of the template. I will try to improve it upon in near future.

Scott Adams has again quoted IIT in his recent dilbert clip on 3rd September. Here is the link of it http://www.dilbert.com/comics/dilbert/archive/dilbert-20050903.html Here is the Clip:-

Today seems to be a great day for me. Firstly I have done fairly well (as compared to previous mockCAT PT tests) in today's PT PracCAT test 01. Hope I will get a better percentile than previous tests.

Secondly today there was water-polo match between "Patel Hall" and "Neheru Hall". I happens to be the senior most player of Patel Hall. Frankly speaking towards the beggining of this year when we have not done enough practise i was quite sceptical about the performance of our team. But our confidence got a boost when we gave a good competition to "Azad Hall" water polo team during some friendly water-polo matches before the actual inter-hall competition started.

Today we had our first inter-hall water-polo match with neheru. Neheru has got a very strong team. It had already beaten RK in yesterday's match. The game strategy developed after viewing yesterday's match between RK and Neheru really does a miracle to us. Using that strategy we can almost successfully resisted neheru's attack. Co-ordination amongst fellow team-mates are at its best. Everyone in the team has given more than 100% of them in today's match. I myself got hallucinated by the coordination, effort, and performance of my team. Unlike previous years matches there were minimal amount of foul in this match. Today's match between patel and neheru is worth viewing.

But Unfortunately we loose from neheru by 11-9. But the unexpected and unassumed effort, coordination, and performance shown by patel hall team will be a great asset in future matches (happens to be on tommarow). Hopes we will win the coming game with RK.

Very few moments came to ones life when one get satisfaction even in the face of faliure. Such a moment had came to me today after the match. Even after loosing the match from Neheru I was quite satisfied and happy with the performance we gave today. No doubt there was unhappiness due to the loss of match, but the satsifaction because of achieving the unexpected, clearing the pshycological barier to achieve new hights are far strong to eclispe the previous one. By the way the true playing spirit lies in zeal to play with 100% of you, not in winning or loosing.

Truely today is a great day for me.
