It is just I love to share with others on my so limited knowledge. I am in no way an expert in what I'm sharing about.The knowledge which is shared in this blog can be beneficial for some people and can be "rubbish" for some other people.

Especially on data structure. It has been a lot of problem for me.Walking through hard roadI have a project which requires complex data structure (err maybe its complex for me, but not for others) .

So what is this mean?It is simple.. since the algorithm consists of mathematical and logical, the most basic things for codinghttp://zulprog.blogspot.com/2009/03/random-thought-converting-algorithm.htmlnoreply@blogger.com (zulprog@gmail.com)4tag:blogger.com,1999:blog-1484930994604885168.post-2059503284970994514Wed, 11 Feb 2009 12:35:00 +00002009-04-27T10:18:06.516+08:00AWKI'm now revisiting AWK language for trace file processing. Awk has been widely used for trace file processing, since (I believe) it is easy to do column filtering.The column can be represented using $1 for column 1, $2 for column 2 etc.. , using other language like Tcl requires list manipulation which is not as straight as using AWK.However, of course, the syntax of AWK is a little bit http://zulprog.blogspot.com/2009/02/revisiting-awk-language.htmlnoreply@blogger.com (zulprog@gmail.com)3tag:blogger.com,1999:blog-1484930994604885168.post-4783491227193750556Wed, 04 Feb 2009 02:35:00 +00002009-04-27T10:18:21.493+08:00PROGRAMMING TECHNIQUEI have been conducting microcontroller lab for a while as a lab instructor.Microcontroller consists of both Hardware and Software.
