Application called ‘Track Your Hapiness’ iPhone users will be contacted at random when the day to ask what they are feeling and what they do when answering these questions. The users have the option to decide when and how often they will be notified. So that was quoted from
Mashable, Friday (12/11/2010).

Results of a study published in the journal Science, examined approximately 2250 adults, 58.8 percent of male respondents and 73.9 of them live outside the U.S.. The average age of respondents was 34 years old. Respondents said that they imagine 46.9 percent of the time when the iPhone rang to check their thinking. And for those who say that they imagine are more likely to indicate that they feel unhappy.

Jonathan Schooler, a professor of psychology at the University of California, said the findings should not be used to declare that all people who are dreaming are the ones who are not happy.

According to Schooler, imagination is the key to solving the problem solving ability of a person. There is also evidence that dreaming is also important for creativity.

“Even when there are cases that people who fantasize are not happy, that does not mean people should stop dreaming,” added schooler.

Meanwhile, the applications ‘Track Your Happiness’ has been used by scientists to determine the cause of one’s happiness. To take the survey, click http://www.trackyourhappiness.org, where the user must first answer a few questions before becoming a participant.

This was announced by Northern California’s governor, Bev Perdue, who said take 18 months to complete the data-center. In addition, data centers are also expected to employ 35 to 45 people to operate it (not including the 250 jobs required during the construction process). Data-center was built in Rutherford County, located in west Charlotte, Carolina. Similarly, as quoted by Mashable, Friday (12/11/2010).

Party up and the governor also stated that the data-center is also environmentally friendly energy efficient. Data-center that will employ advanced power management and cooling innovations. In addition it is expected that the data-center energy will reduce dependence on computing and related energy consumption, the energy required by data-center before, several years ago.

Up to replace the data-center his first in January (which is based in Oregon) in order to deal with rapid growth. However the growth of social networking sites are so large, to the point that in the midst of construction, they decided to add data-center capacity.

Previous data-center up as not able to accommodate the growth of user data which soared but now Facebook has added capacity for data-Centernya their site can keep running.

Xinhua on Friday (12/11/2010), reported the virus from breaking into a security application, which then transmits the user’s SIM card to the server that is controlled by a small group of hackers. The hackers will send a message or make a phone call that contains links to games and virus ridden software.

The phone receiver is lifted to open a link or a phone call will be infected. Or messages can also be spread through emails that advise users know to click the link.

Zhou Yonglin, a member of the National Computer Network Emergency Coordination Center, said in the first week the spread of the virus were recorded approximately 1 million units of mobile phones are infected.

Although the service provider of telecommunications has taken steps to reduce the number of infected messages, Shihong Zou, a telecommunications expert at Beijing University of Posts and Telecommunications said that updating the virus may begin to send a message back, so it is difficult to see any suspicious activity on mobile users .

Oke, Kita akan langsung membahas masalah yang pertama. Sebenarnya tidak terlalu banyak yang saya ketahui. Langsung saja Hypertext bersifat non linier yang berarti memiliki percabangan/banyak pilihan, sehingga pengaksesan informasi dapat dilakukan secara random.

Selanjutnya, adalah membahas mengenai disorientation. Disorientation sangat erat hubungannya dengan masalah navigasi, masalah disorientation disini bahwa user tidak mengetahui cara untuk mengakses hypertext dan lebih bingung lagi ketika mengetahui tata ruang dari frame dalam jaringan hypertext tersebut.
Untuk mengurangi masalah disorientation dapat dilakukan hal-hal sebagai berikut:
1. Hilangkan artikel yang membosankan
2. Gunakan penunjuk arah
3. Hindari rantai link yang panjang
4. Hendaknya ada tombol “Home” atau screen Utama ataupun automatic backtracking.

Selanjutnya adalah masalah Cognitive Overload. Cognitive Overload merupakan beban yang berlebihan pada Hypertext, seperti terlalu banyaknya link yang dapat mempersulit user sehingga dapat menimbulkan ketidaksenangan user dalam menggunakan aplikasi web.
Masalah Cognitive Overload dapat dikurangi dengan :
1. Menyediakan fasilitas searching
2. Menyediakan fungsi help untuk aplikasi web
3. Menyediakan Glossary untuk istilah yang mungkin tidak familier
4. Mengurangi bilangan Hypertext pada suatu node.
