How I know Linux
About six years ago,I had known Linux,which I just seen as a free toy compared to windows.
However,after having read an article written by wangyin who is a Thinghua student,I thought
I may have a try.

The start
The beginning is hard,I must solve each problem I encoutered such as Network access,Chinese output.I was nearly crazy!But in this process I really learnt much on how computer works.

Now
Now I began to be used to work in Linux.
Most important I understand the philosphy in Linux is completely from Windows.

There are two points.

First,in Linux you have the fully freedom to manage your computer.
That means computer must adapt to your taste,not Bill Gates's.At the same time,to be the owner yourself also means you must be responsible for yourself.

Second,simple is powerful.\\Each tool should be professional.In windows,
if you want to edit some text,you must install word,powerpoint.
If you want to write program,you must instll VC++.
Each of these program provide a integrated environment.
You must obey the rules of the environment,I think that just like an animal.
However in Linux you only need to work in shell to start each command such as vim,mutt,tex etc.Each tool complete the work professionally and then pass the work to another program so the wholework is completed by coopration.
That's the essential philosphy of Unix including Linux.
The rate is very high compared to Wins.

In summary,if you want to enjoy the pleasure of work,please love Linux,love her philosophy.

The long march through Computing methods:Runge methods

The graph above (which I made using Octave) shows the Runge phenonmenon in polynomial intepolation,

This term I chose an interesting cource called Computing method,
someone think it dull,but I am interested in it very much.
Only by that can I realize the power of Computing.
By the way Matlab is a great tool.
However I've not enough money to pay for it,so I decided to use Octave(a free numerical computing program)instead,that is good too!

MMIX:Simple is beauty

While reading The Art of Computer Programming,I realized MIX is not so good a design for I have to remember so many confusing commands just like x86.

Forunately,Knuth has found MMIX,a simple and concise RISC architecture
which leads me to the wonderful world of Computing.You just need to remember some basic and simple rule to control the whole computing process.That is the really powerful.
Maybe the secret of God is just to run the world in a simple logic,and that's why God is powerful.
How I wished I can create such simple and powerful tool someday!
