To study Fourie transform

I am studying computing Fourie transform.

It is difficult for me to convert from computing integral to sum.

I am wrong about width of terms, so I miss that sum of each terms divided by length.
I awake that length is a number of input data times width, therefore sum of each terms divided by a number of input data.

I am ashamed.

I can not believe Windows is more popular than Ubuntu

I live in Japan.

My friends and person in my office like windows, since it is useful.

I can not believe their words.

Windows do not have develop tools in default.

Additionally, it is difficult to install software because dynamic load system is complication.

Ubuntu is different from windows. Installing software is easy! There is a lot of develop tools.

Anything can be done in Ubuntu, to program, to hear music, to see movie.

But my friends and person in my office can not tell great things about Ubuntu.




I think Ubuntu is good, but I don't think it's perfect. Ubuntu is lacking 3D game!!

I find out good page for programming of load 3ds.

When I search web page writted 3ds file format, I find out good web page.


This page address is http://www.xbdev.net/3dformats/3ds/3ds.php.

It is important for me that text of page is easily understandable and sample is writted in page simply.

This page fit well with my needs.

I am a programmer.

I start to weblog in blogger.

I am japanese, but this blog is writted in English.
Maybe I miss spell, sorry.

Kind regards.
