conclusion

This is the last week of 236. Some classmates feel that this course is very easy. I don’t think so. This course is the most difficult one I have taken. Base on my programming experience, I feel some courses most students consider as tough, like 209, are not famous as their reputation. But I lack some theory fundamentals of computer. I had not learned any theory of computer before. I should learn some by myself. (Actually no theory skills need to be used during my work) That is the reason why I come back to school at this age. 236 is one of challenging courses for me, another one is mathematics. 

We are going to take final next week. Due to my poor term test 2, I had to go over the materials carefully for getting better mark.

About Blog

This is the first curse to require us write down a blog. I have not token higher level courses. Maybe there is another one asks us to do the same thing. I don’t know. Is that challenging? For me, No. I am keeping my personal blog since 2005. In my personal blog, I wrote articles for questions of interview, my opinion of programming, and some updated processing of the book I am translating. But, I have never thought about putting down my feeling about course. That should be a good idea to extend the topic of my blog. I will figure out a new category during the holiday break.

I do not write their blog by weekly. Sometimes I prepared the tests or quizzes, so I had to postpone updating my blog. But most time I could not remember to do this until some classmates asked “do you write your blog recently?” when we were chatting. So, everyone who always forgets to keep blog should set their clock alert to “wake up wake up, you have blog to write.”

Chapter 7: Regular Expression

The last part of this course is about regular expression. I have being used regular expression for a long time.  The material of lecture introduced is easy for sample. They include 0 and 1 only. (Oh, I am wrong, empty and null are included.)In practice, regular expression involves all characters and signs, like email address, http links or formatted numbers. So, the content we learned looks no useful. Maybe there is higher level course that expends this basic skill to introduce more complicated samples like we meet in the work.

So far, I do not know the usage of automata in the live. I remember I started to use regular expression at beginning of this century with some programming language(JAVA or C#??). Base on my opinion, regular expression and automata were developed with language development. So, we use regular expression to match search. Is it the unique application for regular expression?
