New Development of XML

XML (Extensible Markup Language) has been very popular for web application development. Derived from SGML, XML is a very flexible text-format. For more information, visit: http://www.w3.org/XML/.

XML usage is not just in the Web application. There are other areas that use application based on this language, one example is the US Air Force. In order to increase combat effectivity and efficiency, it uses so called "binary XML". Click here for more information: http://www.mitre.org/news/events/xml4bin/pdf/gilligan_keynote.pdf

In response to the rapid usage of XML, W3C, Web standards body, is planning to speed up XML-based software/application in order to benefit all the users from cell phone carriers to television broadcasters to the military. Users find that XML is too bulky for certain applications such as interactive program and sending data to set-top boxes. W3C proposed to increase the speed processing of XML based applications.

Handphone Virus

Handphone is not protected anymore. There were recents news of handphone virus. One example can be found in: http://newpaper.asia1.com.sg/printfriendly/0,4139,84329,00.html.

The expert views that the threats maybe coming soon through various ways such as MMS, bluetooth, etc.

In my opinion, since their first success in spreading virus, hackers will not stop spreading more and more virus to damage handphone software and even hardware. The first virus, known as Cabir, has caused panic to arise among users. More information about Cabir can be found at:

In conclusion, it is just a matter of short time for all of us to equip our device with a defensive antivirus software. In addition, the damage caused by handphone virus maybe far greater than that of computer due to rapid information flow among users through SMS, MMS, bluetooth, internet, etc.

The techology discussed in the case study is RFID. RFID stands for Radio Frequency Identification. More information about RFID can be found at http://en.wikipedia.org/wiki/RFID. RFID usage all over the world is spreading widely, ranging from animal identification, library loan system, airport baggage tracking, and many more. One example of RFID usage can be found at the following link or can be downloaded here (Note: file size is big). The link provides excellent and clear diagram on the use of RFID in retailers' supply chain management.

In my opinion, RFID is an excellent technology, simple, cheap, yet powerful. I believe in near future its usage will be widespread. The drawbacks of this technology is high cost for its active chip and high concern of customer privacy.
