Re:    Thanks to those who replied...

First of all, I like to thank many of you for replying to my
informal feedback form. It is enough for me to write my short article.

I am in the midst of compiling the results of the feedback exercise.
So far, I have got 26 responses -- including two of you who replied 
from China -- thank you very much for the extra efforts you put in.
To those who have not replied and are free -- hey, I know there are
some of you out there - do send in your reply -- it is not too late.

To those who have replied -- thanks for the detailed and wonderful
comments.  It is most refreshing for me to learn from them.
I would like to compile all the comments and mail them back to all
of you-- without names or identities of the people making the comments.

To do this, I hope to get one volunteer to assist -- this volunteer
must also promise to keep the info to himself/herself. 
Can I ask for one person to email me if you are willing to 
help compile this.  Thank you in advance.
(Those doing special term should NOT do this -- special term is 
stressful enough.)

Lastly, I hope that all of you are having a rewarding and enriching
vacation / special term. Also I hope that this vacation will also
provide all of you with lots and lots of problem solving opportunities
- remember - problem solving opportunities abound everywhere and anywhere.
Let me know about some interesting ones that you come across.

Did anyone remember that in my first Problem-Solving Lecture, I 
mentioned that one of my former student sent me a puzzle?
I am enclosing it for your enjoyment and hope that you will also
send me new ones you come across.

Regards, --hon-wai

Wai Hwang:

   Thank you for the puzzle.

   And by coincidence, I was doing a lecture on problem solving
   at the time your mail was sent to me! And I gave out the
   article on "Cattywampus" to them.

   I am leading an IT stream of sorts -- this time called 
   the Special Programme in DISCS -- a programme that is aimed
   at preparing some of our top DISCS students for research.
   This pioneer batch, we have 60 studens.

   You can take a look at some un-updated info on the SPD 
   in the SPD homepage -- 
       www.iscs.nus.edu.sg/~leonghw/SPD
   and also take a look at some of my recent activities in my
   homepage
       www.iscs.nus.edu.sg/~leonghw
     
   How is work for you these days?

Regards, --hon-wai
