the issue of privacy in networked computer

My mom is a business woman, she has two computers. The computer for her business work and materials, she never connects to the internet. She told me about that the Internet was dangerous, the reason she does it is because there are some issue of privacy in networked computer.

Privacy refers to the ability of an individual or group to seclude themselves or information about themselves and thereby reveal themselves selectively. Along with the development of computer science and internet, new issues concerning privacy start to emerge.

In my perspective, I think the first issue mainly focused on people have a lack of the awareness of privacy protection. Through my research, about 62% of people do not how to protect their privacy online.

Without the awareness of how to protect privacy online, people are generally vulnerable when someone violate their privacy online. 

Secondly, huge internet companies are stealing people's private information through their database and sell them to other companies. For instance, Hotmail and G-mail sell their clients information to related companies, in exchange for money. The users won't directly get hurt, but it is still disrespect to its users.

Also, Facebook and Google are using a similar approach to get a big amount of money.

Thirdly, the increasing number of professional hacker and people who want to know others' privacy for various purposes also become a issue of privacy in networked computer.

Finally, the lack of internet legal protection. According to the following data, 

the legislation system towards internet privacy is not integrated. Therefore, governments and relevant organizations need to set new laws and rules to protect one online privacy.

I am so happy to take CSC 104

The semester is almost finished.

I had last CSC class last week, and I think I learned some stuff.

Computer has always been my favorite,but I am a commerce student, I don't need to master the computer. So I picked the CSC 104, to enjoy the process of learning computer and learn some practical computer programming.

I have to admit that I am not a huge fan of computer history, but the computer programming is so fancy.

In project 2, I wrote the program the professor required. At first, I found it was extremely hard. Big-Band has always been my weakness, I sometimes was confused about it.

However, I asked some of my friends who are taking the course, and we grouped up and solved the program.

The program is pretty interesting, and also complicated. I learned a lot from it.

It definitely increases my capability of writing a program with certain objects.

The second last class

I still can't believe that the course is ending soon, I still hope I can learn more from this course.Happy but sad.

We learned something really interesting this week, especially the Drracket part.

For example:

; flatten : list -> list
(define (flatten L)
(cond
[(cons? L) (apply append (map flatten L))]
[else (list L)]))

I found this was extremely difficult at first, and I had no idea about it. However, after a lot of practice, by doing the question steps by steps, I finally got the question.

I was also pretty happy about getting all quiz answers right. Hope I can do good on this course.

what's something you enjoyed this week in class? (catch up for last week since write the wrong topic)

Internet! Thanks to the internet, I gotta play this wonderful game.

LOL!

In this week's class,  we talked about the Internet. I think internet is what the world so great.It provides us information,entertainment and new ways to communication.

For example, we can find resources for our writing report,we can play game and watch youtube videos and we can talk to people through Facebook and Skype.

We also learned three different models: 

Token ring

bus configuration 

                                           and star configuration

I personally like the bus configurations, because it is the basic configuration about internet.

Questions and concerns so far in this course.

In this course, I think the course materials are generally not very hard to understand. After all, this is a intro course to computer science.

First general question is how to design a function or program. Usually, I know the result of act certain definition in drracket, but it is very frustrating to write a program with certain purpose. To conquer this, I will practice more computer programming on my laptop and read more programs.

Second question is the history of the computer. Again, with the aid sheet, it is not a problem to remember all the history. However, it is still hard to write the answer to the intuitive question about the history. To solve this, I decided to memorize the history and go beyond, think through it.

I hope everyone can have a good mark on this course.

How did the test go?

This week, I had my second term test, which was okay.

I found that the first part which refers to history are generally harder than the second part which testing the drracket skills.

I am pretty confident about the second part, but for the first part, I am not sure about it.

Good luck to me, and good luck to anyone. ;)

how does this week course material relate to other course?

In class, we talked about the revolution about the labour market along with the revolution in computer field. I think it is very closed to what I learned in Intro to Management class. 

The component of the labour market has been changed drastically, the young generation are generally looking for jobs that works 40 hours per week, instead of more hours work, even though the work with more hours usually earn more.

However, the reduction in work hours led to a higher productivity. Because that people are more efficient nowadays then before. Which matches the point of my Management course.

Without computer, I might work for 10 hours and finish my daily plan. Yet, with the computer, I can finish those work in 5 hours and do some extra work in 3 hours and if necessary to work for 10 hours and I will definitely chill for two more hours since the plan has been done.

Therefore, it is understandable the work hour has been reduced to 8 hours. And it is a really good complement to my management course.

OMG - best NBA player

Kevin Love rules!

The NBA today named Minnesota Timberwolves forward Kevin Love as its Western Conference Player of the Week for games played October 29 – November 3. Love becomes the sixth different Wolves player in club history to be named Player of the Week, earning the award for the first time in his five-year career. 

Week 1: uncertainty

uncertainty

After entering university of Toronto, I have encountered a new level of stress. Interacting with my peers had triggered questions about my future, how I did on assignments and tests, and many other things. Life in the presence is so different from before, and in this process of adjusting to the new environment, the uncertain concerns are bringing me additional stress.  

Everything seems to be happening so fast, and before you realize, it has been almost two months since school started. In this resourceful and academically outstanding institution, there are so many interdisciplinary studies to choose from in the upcoming years, each leading to different paths and opportunities. I am uncertain about the best options for me – ones that are the most advantageous for my future. 

I often hear rumors from upper year students regarding the level of difficulty of courses I am taking and the high fall out rate that occurs at this university. This brings me stress as I imagine myself disappointing my parents and not being able to meet up to their expectations. 

It scares me, the thought of failure, but it is the fear that drives me forward. This is all a new stage in life that I must learn to face, urging me to look forward to a new learning experience here at U of T, both intellectually and socially. The challenges that I will encounter are a part of this valuable learning process, for which I am excited to overcome them and grow from each mistake.




Success. How bad do I want it?
