Today, Vice President, Prof. Kar Yan Tam came as a guest speaker at the ISMT101 class.� He gave some very nice arguments about how IT is needed in the industry and how students can benefit from a degree in IT.� Some numbers are worth taking down:

The students in “Global Business” track are the students came in with highest� scores, followed by “Quantative Finance”. At the point of graduation, the “Global Business” students indeed obtain the highest entry salary, around HK$14,000/month.� However, the runner-up in terms of highest paid graduates is not QF, but IT.� Other majors, like accounting, etc. lags behind to get an average salary around HK$11,500.

The other speaker Leroy Yau from Ernst&Young also reported something interesting about IT auditing.� When he joined the firm 10 years ago, there were only 5 people working in IT auditing, then 5 years ago, his group had 20 people.� This year, the number of people is more than 200, and it is still increasing at the speed of 30-50% per year.

I suspect we are going through a period for IT jobs similar to the one for IT investment that confused� practitioners and academics alike: the Productivity Paradox period.� (c.f. Robert Solow)

Maybe the IT jobs are shifting toward more sophisticated IT professionals rather than staying for the programmers.� Similar for the case of shifting from blue-collar jobs to white-collar jobs in the past.

David Autor from MIT wrote a paper long time ago about skill content: The Skill Content of Recent Technological Change: An Empirical Exploration (David H. Autor, Frank Levy and Richard J. Murname, November 2003, Quarterly Journal of Economics, 118(4)) . Another his famous paper is :Wiring the Labor Market. (David H. Autor, Winter 2001, Journal of Economic Perspectives, 15(1))

I think these all point to one direction: IT job is in great need, but people need to be prepared to change the mind set.� They are not about programming.� They are about using IT effectively in the corporate context, and a good understanding of both IT and business/management is needed for these jobs.

IT auditing is probably a good marriage between IT and accounting, I can think about other good examples: IT&Marketing, IT&Finance, IT&OM, in fact IT can be used in all aspects of the business world, and a good knowledge in these surely creates a nice competitive advantage over other potential combinations.

Using the worst artistic tool (a.k.a Microsoft Paint) to draw Mona Lisa, very impressive.

This one draws John Locke from “Lost” in� Photoshop.

Youtube clips appear quite often in my recent blog entries.� I do it only because I can (with this Viper’s Video plugin).�� A deeper reason is that you can find a lot of extremely creative works in youtube.

A little boy was doing his math homework. He said to himself, �Two plus five, that son of a bitch is seven.
Three plus six, that son of a bitch is nine�.�
His mother heard what he was saying and gasped, �What are you doing?�
The little boy answered, �I�m doing my math homework, Mum.�
�And this is how your teacher taught you to do it?� the mother asked
�Yes,� he answered.
Infuriated, the mother asked the teacher the next day, �What are you teaching my son in math?�
The teacher replied, �Right now, we are learning addition.�
The mother asked, �And are you teachingthem to say two plus two, that son of a bitch is four?�
After the teacher stopped laughing, she answered,
�What I taught them was, two plus two, THE SUM OF WHICH, is four.�

No thoughts, sorry. I decide to remain silent for this one.

Came across the fascinating website: Prime Number Spiral

Number spirals are very simple. To make one, we just write the non-negative integers on a ribbon and roll it up with zero at the center. The trick is to arrange the spiral so all the perfect squares (1, 4, 9, 16, etc.) line up in a row on the right side: Figure 1 If we continue winding for a while and zoom out a bit, the result looks like this:

If we zoom out even further and remove everything except the dots that indicate the locations of integers, we get the next illustration. It shows 2026 dots:

Figure 3

Let’s try making the primes darker than the non-primes:

The primes seem to cluster along certain curves. Let’s zoom out even further to get a better look. The following number spiral shows all the primes that occur within the first 46,656 non-negative integers. (For clarity, non-primes have been left out.)

Figure 5

It looks as though primes tend to concentrate in certain curves that swoop away to the northwest and southwest, like the curve marked by the blue arrow.

On the next few pages of this website, we’ll investigate these patterns and try to make sense out of them.

The young generation may not appreciate Michael Jackson’s music, but when I was young, his music video was the first I have ever got on hold and really liked. (The sample may not be representative for me as by that time in China, all music are the same, and they are meant to praise something). Anyway, it was refreshing to watch the fatastic dance.

My favorate music of MJ? To me, it was “Heal the World”, I really like the soft melody.

Today, I wanted to search for a Harvard Business Review article on online collaboration. So I typed “Harvard Business School” as the search term, below is what got returned.
