Peer-to-Peer File Sharing

Peer-to-Peer(P2P) file sharing has been very popular for since the past few years. Programs such as Kazaa, BitTorrent, Shareaza, etc provide links to a user to huge resources of software from millions or even billions of users all around the world and allow user to download those software for "free". So far, lots of controversies have aroused due to wide usage of P2P, especially by home user and university community. From vendors' point, P2P is a big nightmare, but from users' point, P2P is a heaven. Here is an article from Wired Magazine entitled "The BitTorrent Effect".

Feedback

I find out that all the sessions so far have been very interesting. Contrary to all those criticisms and negative feedback, I really like this subject. Also, for the venue, I prefer to have the class at the IT lab because I find that the environment there is more conducive for learning. These are reasons why I love this subject:
  • I know there are some assignments we need no do each week. However, I realize that those assignments are quite challenging. From those assignments, I learn new things such as blogging, making flash presentation, HTML, etc.
  • The course structure is great. I believe with the project included it will help us to think something different and innovative to be applied in real life situation. The practical aspect is much better than just learning theory upon theory every week.
  • The lecturer, Prof. Gilbert, has done a great job. In his teachings, he always provides us with the latest news and knowledge related to technologies, features of mobile and electronic commerce.

In conclusion, so far I really enjoy the couse. I'm looking forward to joining the remaining sessions of this course.

The Power of Mobile Technology

I just found an interesting article on how mobile technology has helped people to communicate in the tsunami affected region.

Cutting-Edge Telecommunications Help Reconnect Asia's Tsunami-Displaced People (or PDF)

Little did I realize the usage of mobile communication before I read this article. However, soon after reading it, suddenly all became crystal clear to me. In a calamity such as in Aceh and Sri Lanka, home phone or fixed phone network is crippled. Well, say goodbye to wired phone. The phone line was probably swept and destroyed by the massive water. Also, the device might probably submerged somewhere below the water.

With recent technology advancement, it is not impossible anymore now to communicate in such environment. When wire is not needed anymore and when people move from one place to another, wireless and mobile technology provide the answer. In fact, they have helped a lot.

Mobile Phone Wallet

Here is an interesting article about mobile phone wallet (a possible expansion of mobile phone functionalities we discussed last seminar): link or PDF file.

In line with time, mobile phone is more than just a phone. With added features like camera, scheduler, PDA, radio, and many more, it becomes a versatile device. Because of its personal and mobile nature, manufacturers are trying to add in more features such as wallet, key, movie player, and many more. The point is that mobile phone will act as disruptive technology to sustaining technologies such as credit card, video/mp3 player, and digital camera.

In the article, Japan's NTT DoCoMo has sucessfully integrated mobile wallet feature that can store up to 50,000 Yen (US$ 450) limit for daily transactions (shopping, buying from vending machines, eating in restaurants, playing arcade, etc) by just flashing your mobile phone to the reader machine. It's so easy, quick, convenient, and no keypressing needed.



The use of mobile wallet phone in Japan has contributed much in terms of efficiency and speed. It is observed that so far the technology is still safe. There has been no attack from hacker. Also, in case people lose their handsets, DoCoMo will lock the phone so that no one can use it for calls or transactions.

However, experts are concern for further issues of security and privacy. Problems may arise when hackers develop software that can steal the virtual money instantly. In addition, government or telecom company could track individual spendings and physical movements which may disturb privacy.

Interesting Insights and Findings:

  • There is no exact corellation between cost and value. It does not mean that if we want to retrieve high-value information we must pay with high cost. There are cases whereby we obtain information that is highly valued at low cost or even no cost at all.
  • The information comes from 3 broad categories: people, electronic media, and printed materials.
  • Information that has important implications or relationship to one's personal life tends to be highly valued.
  • In addition, information that we need urgently tends to be highly valued.
  • Obtaining some information may become people's routines. For example, reading daily news and checking mailbox. However, there is also information that people acquire ignited by occurence of unexpected events. For example, when we see crowds we may to know what is happening.
