Sorry to all requests: I cannot fulfill it. I thought that I would be quite relaxed in the winter break, but I was wrong. Sheer amount of workload haunted me during the holiday. I am really sorry I cannot make my promises. Short e-mail questions I did reply, but longer ones: Sorry if I didn't reply. Moreover, some of the e-mails were lost during last system crash. If you didn't get reply, I apologize for this as well.

It's been a very long time since the last update. I'm a bit relaxed now. Hopefully I can write some more chapters this holiday season.
Please people, do not apply web harverster / subscriber / reaper -- what you may call this. This put a very large burden on Geocities. I've got several warnings on bandwidth usage, which is very strange for a small site like this. I suspect that some of you may have used these kinds of tools. Please don't do that. You can download the tutorial if you want to.
Or, if you want to mirror this site, please e-mail me personally. Don't use crawlers. It puts burdens on the server.
I've got several requests on algorithm columns. OK. I'll try to put up some. If you have Rivest's book, probably you'd notice that's where all my knowledge is from. ;-)
Lastly, an update! On Gauss-Jordan elimination used in calculating matrix.

My condolences to the victims family and relatives in New York, pentagon, and Pennsylvania.
I'm very busy. Nothing new yet. I don't know whether I could write another tutorial before I defend my thesis. So, for requests: Sorry, I can't fulfill it for now.

Hi everyone! I'm still alive! John Mathys points an error in Pascal lesson 1 chapter 14. It is now corrected: here.
I'm very busy, as usual...

Finally: An Update! This is a half done chapter 2 lesson 1 of C/C++.
I've been very busy. Even at this time. Sorry for the unanswered e-mails.
This site is more than a year old now. Or more precisely, it has been more than one year since the resurrection of this site. Yes, resurrection. This site was once dead from 1997-2000.

I cancelled the idea on having the tutorial done with KPresenter. The files it creates are simply too big. I can't get all the tutorial setup in this tiny 15 MB space.
Then, I create my own, based on the template of KPresenter. Click here for a preview of the new C Lesson 1 Chapter 1.
