computational tools

Today I found that the main problem-- no proper computational plateform, has been resolved. In factly, the zaphon machine is very good for programming and do computation. I just thought the machine is a little strange, and Kai should install little software on it. So did not inspected it carefully. And install two computer is a tire work, so i alwarys ignore it.

Then i should use it!

And i should ask kai whether i should intall a matlab on this mathine to analysis the data directly. So some programming rules on this machine.

besides editor many other things are also important. Spend much time on ftp/make script is not a good thing for me. So try to get to use some power tools is important for me.

Programming tools on win32 is good, and use emacs to programming seems too smart. I wanna to use some stupid toos.

X Window System - Wikipedia, the free encyclopedia

X Window System - Wikipedia, the free encyclopedia: "Limitations and criticisms of X

The UNIX-HATERS Handbook devoted an entire chapter, 'The X-Windows Disaster', to the problems of X in the late 1980s and early 1990s. Why X Is Not Our Ideal Window System (1990) by Gajewska, Manasse and McCormack detailed problems in the protocol with recommendations for improvement."

The C Shell

The C Shell: "A special form of redirection is used in shell scripts.

calculate << END_OF_FILE
...
...
END_OF_FILE

In this form, the input is taken from the current file (usually the shell script file) until the string following the '<<' is found.

If the special variable, noclobber is set, if any redirection operation will overwrite an existing file, an error message is given and the redirection will fail. In order to force an overwrite of an existing file using redirection, append an exclamation point (!) after the redirection command. For example for the command:

date >! datefile

The file datefile will be overwritten regardless of its existence.

Adding an ampersand (&) to the end of an output redirection command will combine both the standard error and the standard output and place the output into the specified file."

At the end however, is another redirect which is indicating that stderr (file descriptor 2) should also be sent into the stdout (file descriptor 1), which in this case is our out_file. To say the same thing in C Shell the syntax looks simpler, but is harder to read because the descriptor numbers are "
