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.
When one start writting Javascript in patterns like the module pattern, then sooner or later he would want to maintain the state when an event handler is called. The reason I am still using YUI to handle my event handling code is because I like how state can be maintained.
The making of this plugin was completely a random act of hand-itchiness. A friend of mine (@cornguo) published a fun app online. There is a name for this kind of app, but I can’t recall at the moment. It typically displays some buttons (usually in a grid), and clicking them causes some sound to be played. The interesting part in cornguo’s app is that there’s a text-input field where the name of the buttons can be typed-in for replaying.
Just happened to see this post a few months ago, and the author created another cloud that uses almost the same technique to ‘visualize’ a list of countries. The author uses PHP to generate the cloud originally and I thought I may be able to do in javascript. After some quick coding I managed to produce something similar to the first example, source code after the jump.
Recently I am being assigned to work on a FSM based workflow system to enable my other colleagues to use it in their application. I am rather impressed with the simplicity of the workflow system (initially designed by my Technical Director) and decided to post some notes here. The workflow system was developed for CodeIgniter PHP framework and Drupal CMS.
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.
