As professor mentioned, I am going to talk about “Computer Ethic” in my blog. According to Wikipedia, Computer ethics is a branch of practical philosophy which deals with how computing professionals should make decisions regarding professional and social conduct. The term "computer ethics" was first coined by Walter Maner in the mid-1970s, but only since the 1990s has it started being integrated into professional development programs in academic settings. The conceptual foundations of computer ethics are investigated by information ethics, a branch of philosophical ethics established by Luciano Floridi. Computer ethics is a very important topic in computer applications.
I have search couple of articles which relate to our topic Computer Ethic. “The iPhone Hacking Kit, step by step” is the one I like because iPhone is the hottest topic recently. The author teaches everyone hacking iPhone step by step. People can install other applications after unlock the iPhone. It is free software, just taking 30 – 45 minutes.
This is good news for publics, who have iPhone, but it is painful for AT&T. Publics will be more flexible about using their phone; however, AT&T will lose the ability to hold their customer using their service.

Negotiation
According to Wikipedia.com, broadly speaking, negotiation is an interaction of influences. Such interactions, for example, include the process of resolving disputes, agreeing upon courses of action, bargaining for individual or collective advantage, or crafting outcomes to satisfy various interests. Negotiation is thus a form of alternative dispute resolution.
Last class we did negotiation in class. Professor gave us 1 group assignment which divided by 2 steps. First of all, each individual had their own values sheet. Everyone knew which solution the best for his/her is. After discussion, because we wanted to make us to be “win-win” status, our group decided to share our value sheets and use Microsoft Excel to calculate one best solution which makes everyone to get maximum value. However, we had a problem. There was one student’s score having a very low score. Excel gave us two best solutions for solving our question. First one the score average was great. It was 4.7. Two of us got around 9 points, but one of us just got 2 points. Second one, the average was 4.3, but the two guys’ 9 points changing to be 6-7 points. The one who got only 2 points in the first method got 4 points. Because this problem, we did grouped negotiation. Finally, the lower score student decided chose the first one. She wanted to keep other student with a high score.
Later, professor gave each group another values sheet. Students tried to use the same strategies as the first step. We shared the value sheets importations; however, this time the rule had changed a little bit. The score was based on the difference of the each group’s choice. Based on this rule, we used a lower score. Fortunately, we got a nice score at the end of this class.
Through this class, we learned that negotiation involves three basic elements: process, behavior and substance.
The process refers to how the parties negotiate: the context of the negotiations, the parties to the negotiations, the tactics used by the parties, and the sequence and stages in which all of these play out.
Behaviors to the relationships among these parties, the communication between them and the styles they adopt.
The substance refers to what the parties negotiate over: the agenda, the issues (positions and - more helpfully - interests), the options, and the agreement(s) reached at the end.Skilled negotiators may use a variety of tactics ranging from a straight forward presentation of demands or setting of preconditions to more deceptive approaches such as cherry picking. Intimidation and salami tactics may also play a part in swaying the outcome of negotiations.

Systems Development Life Cycle
Last class professor mentioned about program life cycle. It is a very interesting topic. Systems Development Life Cycle (SDLC) or sometimes just (SLC) is defined by the U.S. Department of Justice (DoJ) as a software development process, although it is also a distinct process independent of software or other information technology considerations. It is used by a systems analyst to develop an information system, including requirements, validation, training, and user ownership through investigation, analysis, design, implementation, and maintenance. SDLC is also known as information systems development or application development.
I searched some articles about SDLC. “Using the Program Life Cycle Can Increase Your Return on Time Invested” is one which shows the benefits of SDLC. It truly describes how SDLS works and increases the return on time invested. It gives some examples about each SDLS steps to explain why SDLC is worth. It claims that maximizing the quality and quantity of programs is key to an Extension educator's success. I believe this is a very helpful article for who is first time touching SDLC and who is developing a software.

Brigadoon Bed and Breakfast
The most interesting thing I learned in this week is Brigadoon Bed and Breakfast. Two teams pointed out lots of problem they have. There is one problem I am really interested in which is Website homepage. Theirs homepage just simply has Links to other Brigadoon Ads, Request more info on Brigadoon B&B, and How to find us. It is a very boring and unfriendly homepage. They are refusing customers who want to order room through WWW. I look up other hotel’s homepage such as Sheraton. They offer on-line reservation and vacation ideas. It makes customer more satisfied and friendly. People even have not been there, they have already experienced home feeling. Sheraton’s homepage uses orange as the main color. It make people feel warm even thought it’s now winter. In contrast, Brigadoon Bed and Breakfast still using blue and gray as the main color. We have to say that Brigadoon B&B does not pay attention on their image and customer service.
These two website are good for people or travel agency who want to order room, because they can directly get information from these two web pages. It is good for Sheraton, but Brigadoon B&B. Sheraton will gain more customers since their homepage.
