JAVA & Internet Application System Design: 網際網路應用系統設計作業三 ( 3/14 Homework)

1. Use Google to search. List some of the critiques about Skype. Make comments on each of these critiques.

a. Are you fed up with contacts stored on local machine?

It depends. Although the new released beta version solved the problem, I still have some doubts. If the server is down, the log-in is a problem. For instance, the MSN sometimes does its maintenance, millions of people can’t chat.

b. Can 9 Million Skype Users Be Wrong?

I think this is an interesting article. When everybody is criticize the Skype’s security, however, I worried it’s too safe and it may be used by criminal to kidnap or other illegal usage. Unlike telephone or cell phone, polices can still check the communication record, but Skype is not regulated by any law.

2. RSS and Atom are two methods that can be used to support site feed. Explain RSS and Atom with examples.

RSS & Atom

What is RSS?

What is Atom?

Firstly, we can try to read the RSS history.

RSS is the milestone but not the best. From the Atom project, I find out that RSS has some problem not fixed. So the Atom Project tries to fix the mistake already exists on RSS.

Maybe simply concluded, Atom is the new concept the RSS. The Atom project would like to make different formats and protocols just one format (Atom) and one protocol (HTTP).

NO!

It’s not that simple! Resources on internet tell that it looks like a war between RSS and Atom. By the way, you can say two software giant’s war, SUN and Microsoft.

I’m not quite understood after I read “RSS, Atom, And The Syndication Standards Dance!”

Here are several links of RSS and Atom.
