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.
To do node selection for DOM operations, one typically uses CSS selectors as (probably) popularized by jQuery. However, there is another alternative that is as powerful if not better known as XPath. XPath may be able to do a lot more than just selecting node (which I have no time to find out for now) but I will just focus on how to do node selection in this blog post.
Semantic Web is not just about putting data on the web, but also making links to allow a person as well as a machine to explore the web of data. Links are made in the web of data connects arbitrary things together as described by RDF as opposed to links in the web of hypertext, where links connects to only web-resources. Linkage of arbitrary things then allow related things to be found while performing search.
I wanted to try using virtuoso as the storage engine for Redland but unfortunately there is no librdf-storage-virtuoso package for Ubuntu. After getting some help from @dajobe, I attempted to build the packages myself. Although it takes quite some time to build packages, but not too difficult it seems.
I often struggle to get my Javascript code organized, and have tried numerous ways to do so. I have tried putting relevant code into classes and instantiate as needed, then abuse jQuery’s data() method to store everything (from scalar values to functions and callbacks). Recently, after knowing (briefly) how a jQuery plugin should be written, it does greatly simplify my code.
