Here I present my first program. It's a simple game : eptaxia. This was an old mind game I used to play since I was in high school (in boring classes). I don't know it's real name.

There's a setup package that you can easily install. Also, you can get the source codes of the program.

A Mathematically Challenged Man's Search for Scientific Wisdom
March 2009

When I started doing my homework for Optimal Filtering for Signal Processing class, I said to myself :"How hard can it be?". Soon I realized that it was a fatal mistake.

The whole thing was like a nightmare. Nothing made sense. The equations were composed of some ridiculously complex superscripted and subscripted variables combined with transposed matrices and untransposed some other stuff, which are totally unknowable to most of us.

And then, instead of aiming for the homework, I decided first fully concentrating on Kalman Filter itself. This article is the result of my couple of day's work and reflects the slow learning curves of a "mathematically challenged" person. If you're humble enough to admit that you don't understand this stuff completely, you'll find this material very enlightening.

So, enjoy it!

A review of Crumpler Notebook Bag - Wee Bee
August 2007

I'm not sure whether it's a common problem for notebook owners, but "finding the right notebook bag" was a great challenge for me. After I experienced this bag, I felt that I found the right thing for me. In this review I tried to express my experiences with it. click for Crumpler Wee Bee review

I was once, one of the people who think that the digital books will never replace the joy of reading a real paper book.

It may be true to some extent. But the convenience of reading digital books is so enormous that, I simply starting to ignore the setbacks.

I personally prefer MS Reader to Acrobat Reader for:

- True type font and easy reading
- The aid of dictionary (it's very important for non-native English speakers like me)
- Portability to Pocket PC platform

Here, I want to share e-books. In general, I'll share e-books that I'll create by myself. I also will write an article on "How to create your own e-books".

In order to read LIT files, you should install Microsoft Reader. You can read the books I deliver and thousands of other titles with MS Reader.

There's even a version for PocketPC's, which is my favorite way of reading e-books.

Go, get and install if you don't already have it.
