Notes on codes, projects and everything
Generally, library holds a wide variety of reading materials and providing ample space for quiet study. A full range of services is provided in a library, such as loan, reservation, inter-library loan, reference, online resource, document delivery, photocopying, audiovisual and microform materials.
Initially, the library transactions are handled manually by the library staff. The references are stored using the filing system. This tradition method has raised many inconveniences to the library staff.
Hence, you are required to do some research on the problems that faced by the conventional library management system, and then develop a computerized library system by using the ASP.NET.
A master page is used to set up a consistent look and feel to the website. However, since it is not being discussed in class, therefore we had got to learn that ourselves. We implemented a simple master page to the website and separate the layout and data presenting element using a stylesheet file. The tool used to develop the assignment is Visual Web Developer 2005 Express Edition.
Following included are the screenshots for some main functions.
I saw this article from alistapart, which is about Javascript’s prototypal object orientation. So the article mentioned Douglas Crawford, and I was immediately reminded about my struggle in understanding the language itself. Back then I used to also refer to his site for a lot of notes in Javascript. So I went back to have a quick read, and found this article that discusses the similarity between Javascript and Lisp.
Traversing a tree structure often involves writing a recursive function. However, Python isn’t the best language for this purpose. Therefore I started flattening the tree into a key-value dictonary structure. Logically it is still a tree, but it is physically stored as a dictionary. Therefore it is now easier to write a simple loop to traverse it.
Maintaining state in Javascript is not too difficult once you catch the idea. However, as I am not a super brilliant programmer, it takes me some time to find a way to maintain state as YUI Event does in jQuery.
I was asked to evaluate fuzzy c-means to find out whether it is a good clustering algorithm for my MPhil project. So I spent the whole afternoon reading through some tutorial to get some basic understanding. Then I thought why not implement it in Clojure because it doesn’t look too complicated (I was so wrong…).
Not sure about the others, but the obsession to my coding tools is probably more than I would admit. I have just managed to do a dirty quick hack to manage my VIM configuration settings. While I am sure there are other people doing this, I would like to show my reinvented wheels.
