Summary:
The article talks about there a lot of computer science students in Stanford University who had cheated in some courses in the exam. Before the exam the professor always tried to warn the students not to cheat. A student who has been caught twice said he had never thought he could be caught. The university’s judicial panel reported that almost 22% computer science cases had occurred of the total honor-code violations, and there are only 75% students passing through a course before they graduated. The professor Roberts thought computer sciences courses cheating could be detected hardly. Stanford employs a new system called watchdog to detect the cheating but it can’t find all of them. Professor Roberts created a new system called “collective incentive” that is if one person cheats the whole class will face more pressure on the final exam. But still some students thought cheating is not worth doing, and some students thought the other major students also had cheating; in CS the cheating usually happened in lower-level courses.
Reaction:
Stanford University is the most famous university in the world. The students who studied in Stanford should have enough personal abilities. Computer science courses are really difficult to detect the cheating in. In my opinion the cheating cases that exist not only are the students’ responsibilities, but also show that the management system has problems. If one person cheats in the exam the whole class will be influenced, also should be doubted.
First, the most important thing we should figure out is why so many students choose to cheat in the exam and how to do it. Their purpose should be passing the courses. If the university makes the rules like if the student cheats or helps other cheaters, and he or she will not pass the exam, this will be more efficient. The students can use copy, cut or paste others work as their own. Generally, it is easier to cheat than in other majors, but different computer programs couldn’t be the same with another one. Even a part could be the same, but without another code the program couldn’t be operated. If the professor checks the students’ exam or homework carefully, I thought it can easily find the problems; We can change the exam styles too. For example the professor doesn’t ask the students to write a program instead they need to check the wrong sentences and make it able to be run; it maintains academic standards and makes the cheating more difficult.
Stanford uses the method in which one student cheats and the whole class will be influenced. I thought it is unfair. Other students didn’t do anything wrong so they should not be punished, and it can’t solve the problems. Actually some methods can be instead of it like the students supervise each other or make the rules that helping cheating and cheating are equal to stop them.
Students should be trusted; the goal of the university is try to make the students as good as possible, not only require the score, also the morality. Using the correct way to avoid cheating and helping the students to know what things they can do is the university’s’ responsibility. Students also need to know, trust ourselves, and do as much as we can; that is enough.

Summary:
This article talks about two questions; the first one is what the difference is between the C.C.F.L. laptop screen and the LED laptop screen. C.C.F.L. which is named cold cathode fluorescent lamp, is older and is a cheaper method, but it has some drawbacks, like it includes mercury and it is bad for the environment. The next one is the LED screen. It uses less power and is friendly to the environment, but it is more expensive. Some people prefer vibrant colors or may choose glossy displays. Matte display has less color depth and contrast. The second question is how to protect confidential information. The author suggests making a password archive. Different operating systems have different tools to keep security. Or we can make some copies, install a firewall or unplug the drive. At last the author introduces a tip for icons in Windows 7.
Reaction:
This article is a personal tech who invites questions and answers; he taught many useful experiences to the reader. From his article, he talks about the C.C.F.L. and LED, and how to keep the confidential information in the computer, I just want to share my experience with others.
When I was in high school, my parents had already bought a secondhand laptop for me. During that time, the laptop was much more expensive than it is today, but the quality and function were less. My computer is a C.C.F.L. laptop screen. One day I just put my laptop on the desk and typed. Suddenly the screen went dark and nothing appeared any more. I had tried to find the issues but it did not work. So at last I had given up and prepared to send it to the factory to repair. Afterward I packed the laptop. I found something like water, but it had a the silver color, on the desk. My parents were very nervous and we thought it could be mercury. And we cleaned it very carefully. After that we never chose the cheaper laptop again. And I prefer to pay more money to buy a safe computer. Actually nowdays the C.C.F.L. has almost disappeared. The famous brands of computer manufacturers choose the LED much more even though it is a little expensive.
I have never put my important information or documents on the desktop, but if the computer gets a virus, no matter where I put them, I will still lose them. So I would like to put my important documents in another device like a flash device. Even though the computer has been hacked, but I still keep them. And I don’t agree with the author’s statement that we should set a password archive. it is too easy to decipher the program, and it is inconvenient to open them. So installing security software should be a good idea.
I like the facts that they can share skills. I can learn a lot of information from these answers. So I really hope there will be more articles like this.

Summary:
This article is talking about how a hacker stole the password and why people set their password too easily. Many people prefer to set an easy password. And hackers could try the most common password and break accounts. Some web sites try to lock the account if too many incorrect passwords are typed but it is still not safe. And now, some web sites use mixed letters but social networking and entertainment Web sites still try to make life simpler for users. The experts suggest people remember at least two kinds of password.
Reaction:
After I read the article I remembered there is another kind of password could be safer. It is a card that has been separated into several rows and column; there are different that numbers in every coordinate. If you want to enter your account you need to type the number in different coordinates by random. And some bank use digital security as a one time password. It also can make our account safer.
The only problem is that people still want to remember fewer passwords in their brain. Sometimes it prevents them from forgetting the password and sometimes they are too lazy to remember the password; also typing a lot of letters is a waste of time when they enter the account. In the world today, people have lots of accounts; it is not pratical to make different passwords for each account.
In my own opinion, I suggest people choose a few passwords that are easy to remember. The important accounts use the complex password and the simple password for the less important account. Even though sometimes it is troubling, but it relates to the privacy security, so we couldn’t ignore it. And also it is better that web sites upgrade their firewall to protect from the attack from the hackers. They must Ensure the customer’s accounts safety.

Summary:
This article talks about the customers seem to be increasing online shopping and decreasing the store shopping on thanks giving holiday. Online shopping appears to be up from last year, and this year the sales were led by bigger discounts. Many online shopping stores give different discount to customers. Though online shopping is increasing but it is still a little part of total retail. The reason is shopping online is more convenient than go to the store. But do not expect steep discounting which was offered by e-commerce.
Reaction:
In thanks giving holiday I have ordered some gifts from the store because the e-commerce sites provide free shipping if you consume the money more than XX dollars. For my onion, I prefer to order online instead of go to the busy mall. After compared I found the price has little difference between the online and in store, so I choose the convenient way to by the things I want. The e-commerce uses this method to attract customers. Actually during thanks giving holidays. The shop couldn’t give too much discount any matter you choose which method to consume.
I found some interesting things, that is some store provides coupons to customer but it also can be used by online shopping, you just need to type in the code number and the price will have the same discount. So online shopping is tending to in place of store shopping. The biggest problem for online shopping is the transformer fee will increase the prime cost. But I found that some shop create a good way to solve it. After receive the order online, they will check the local store first. If there has on item that customer wanted, they check the nearest store which has the goods and then lock it. If the customer choose the standard shipment. They will ask the customers to wait for few days. And after all the items, which need to be, send in one place has been prepared. The store will delivery them together. It saves lot of money for transformed. Compare with the prime cost I believe that store still earn the money a lot.
The benefits from information century are people feel convenient. Internet provides a plat to make it to be come true. And public should support the new kind of thing. It needs every person to make contribution.

Summary:
This article talks about a new button named Readability on the Web browser’s toolbar which can eliminate useless things from the web pages when the reader is reading, it aslo can change the font, size and background. The author thought that he don’t like to see the Times-Square blinking when he was reading, but some resmarks doubt about his thought. So author explained that first the button need to be clicked and then worked, second he thought the advertisers should be appeared in the first place, and just click refresh the page to turn back to original. And Readability has more function than ad blocker.
Reaction:
I have the same experience with the author, when I was reading the Web page, some advertisement get out and influence my reading. It was very irritating, and I also use some Web page tools to eliminate the trouble makers. But acturally I thought the reason is not here, the Web makers should consider about the readers situation and make some progress.
As the author said, Web makers should put a fixed place to show the advertisement. Like before the main article, in the top of the page or in the end of the page, also liftside or rightside could be a good choice. If the put the ads everywhere in the article, the reader should turn up or turn down the page and it is very unconveninet. The next idea is the creativers really don’t need to make the ads so complex. Like the bliking, animating and distracting. Maybe they thought it could make the ads more attractive. But if they change the role and become a reader. They will understand the reader couldn’t pay much attentation on their product except they really need. In the same time, the ads make a lot of trouble for reader like somebody careless and click it, it turn on a new Web page immediately. It really makes reader feel boring.
The Web page company rely on the ads to earn money and amount of clicking. But the essence is the more good content the page has, the more visitor it will has. So just make a comfortable reading environment for readers. I think the reader could be more approciate about it and also has the good impression on the Web page.

It is backed by $6 million from investors.

eBay and Amazon.com are the most famous online e-commerce companies. It is difficult for Glyde’s competing, but Glyde was figured out a good idea to attract customers. If they really can make the deal-making process more convenient, a lot of sellers and buyers who felt trouble with the online deal process will tend to choose it.
But they still need to consider some important questions. First, as the article said, they still have no solutions for some sellers who list stolen or bootlegged meterial online. eBay and Amazon.com because of their perfecting process and their online deal making have become very complex. If we just care about the convenient elements, it will cause many unknown problems without safety identification such as the selling of fake. And another problem is how to make customers consent to the credibility of the website. In my opinion, I thought most buyers prefer to choose the complex but safe way to make deals instead of this dealing way. Nobody wants to spend money in an unfamiliar e-commerce website.
Even though they need to face a lot of problems, their idea is creative. It also can make eBay or Amazon.com consider their deal processes. And as in time past, dealing online could be the most convenient way to buy goods for customers without going to the shop.

Summary:
This article talks about how the Chinese online game companies are ready to join the Western markets. It becomes a challenge to the leaders of online games, Electronic Arts and Activision Blizzard. One of the companies is in the final testing stage for an online game which is for the U.S. market. But most U.S. game players prefer to online play with consoles, but analysts said there is a shift toward online gaming which can be played at Internet terminals and cell phones. The analysts think online gaming would be different from console side, and Chinese computer game companies have the operational expertise and business model for global rivals. The revenue of online games is growing fast, but Chinese companies still need to spend much more to promote their products.
Reaction:
Online games have become more and more popular these days, especially for teenagers. It is a potential market for Chinese online game companies. Some of them grab the chance to sell the products abroad; it must be a new challenge for Chinese game makers.
I think there are two big problems that they need to consider. The first is culture shock. Chinese game makers like to combine the Chinese traditional elements into games. For Chinese game players it was very attractive, but the players in western countries maybe don’t like it. If they give up the traditional way to make games and use western cultures, they will have big problems competing against the western companies. Another problem is language. The games need to be translated into English. But the different language may cause negative understanding. For example, a sentence in Chinese may very humorous, but in English it not or it is rude. Also the companies need to pay for translating too many sentences. It costs extra time and money.
But I thought everything needs to be step by step; Chinese online games are joining the western market is quite definite. At first they must face so many troubles. Also I hope that the makers can make some games that still have the Chinese elements for western players; it will help the communication between the different countries. Different players from the world can enjoy the same game; I expect the day is coming.
