The role of computers

Soon people who cannot work with computers will be disadvantaged. To what extends do you agree or disagree?

Many people are talking about the role of computer in the modern life. While some people think that it is best to work as a traditional way which do not need to depend on computer, others believe that it is a huge disadvantages to work without helping of computer. In my opinion, I obviously believe that everybody could gain more advantages if they know how to use computers for processing their work; however, people should not overuse them and I will analyze these aspects in my essay.

Firstly, comparing with traditional way, working with the support of computers can save time. For example, an accountant who uses a normal calculator will spend days on calculating the salary for hundred of employees; but it only take this accountant just under one hour to get the output by using a computer which has been built in an suitable software program. From this example, it is clearly seen that computer help people lessen the time which need process to achieve a task and therefore is a reason that I want to mention.

Furthermore, computers are a cheap meant which people use for exchange information with friends or colleagues. For instance, some softwares running on computer such as yahoo, Gmail allow people to send email to their friends over the Internet without paying no fees. An another example is that people only take a small amount of money to pay for service each month when they use computers to chat or video conference with faraway friends. The above examples totally show that it is very cheap to communicate via computers.

On the other hand, computers can harm to your health. According to the researchers, staring the monitor for hours directly cause your eyes problems such as short sighted. Besides, people play games or overuse computers can easily lead to computer addiction and the consequence is that they do not have time to do exercises to enhance their health. These people become weaker and get some health problems such as heartaches, backache, and so on.

To sum up, people get vast advantages with computers aided working; however the computer should be used reasonable. People take control their time using computer or addict computer. In the future, I believe that people can get more convenient from computers which have more and more applications are implemented and installed.

one side Argument essay

Some people like to eat out while others prefer to have meal at home. Which do you prefer? Use specific reasons and examples to support your answer.

Argument essay

Opinions on food vary tremendously as does an individual’s culinary skill. Thus some people like to eat out while others prefer to stay at home and cook for themselves. For me, I prefer to go to food stands or restaurants as opposed to preparing food at home. Eating in this manner is both more convenient and tastier and I will analyze these areas in my essay.

Firstly, eating in a restaurant is much more convenient than eating at home. For example, when I finish a long day of work, I often do not have enough time to prepare meal for myself at home. Further, many international restaurants line the street where I live. Thus, going to a restaurant is a much more convenient option for me. This is therefore one of the main reasons I prefer restaurant to cooking at home

A second reason is that restaurant food always tastes better than the food I cook. I am not a talented chef by any stretch and the foods I cook never turn out the way I plan. For example, I often overcook foods to the point that they are unpalatable. For this reason, restaurant food is consistently a tastier opinion and is therefore another reason why I prefer buying my meals to preparing them at home.

In conclusion, restaurant food is both more convenient and tastier than my own cooking. Thus, I choose to eat the majority of my meals outside my home and strongly prefer this to cooking for myself. I believe I will continue this lifestyle as long as I am a working person.

Environmental disasters

Nowadays, there have been a variety of environmental disasters that do have huge influence on human species. However, the two terrific issues, which people must not only concentrate on but also give out solutions quickly, are air pollution and global warming. The former causes many serious diseases to human being while the latter creates nature diseases killing people.

First of all, air pollution and global warming kill people in many ways. Air pollution is the main reason that increases a lot of dangerous diseases. For example, lung cancer is caused by breathing and living in a dusty air area and if anyone does have this illness, it will be very hard to treat and the consequence is that most of people who have this kind of illness will be died after several years. From this example, it can be clearly seen that air pollution is a dangerous issue. Furthermore, global warming is the huge second problem that people are facing. As the weather becomes hotter and hotter, the ice in south and north poles melt causing the sea face is higher and is therefore reasons create a lot of disasters which killing thousands of people each year such as flood.

It is clearly seen that human being are severely suffering from these optional disasters. The question is how people tackle these problems. In my opinion, it must be a difficult answer and take years for solving. However, the solutions should be divided into two terms which are short term and long term. The short term includes some actions related every citizen such as holding meeting, saving resources as much as possible, and educating people on environmental knowledge while the long term must aim longer time. One of important things of long term is that the government must legislate at reducing emission pollution air from automobiles, air conditioning. Another one is that the company must quickly find out an alternative fuel replacing coal and petrol as well as improve the quality of vehicle engines.

To sum up, air pollution and global warming are the two of dangerous environmental disasters that people are facing. To deal with these issues, people should have many policies which involve in short and long term. I obviously believe that these problems will be solved in the future depend on well-education of youth generation.

You can download the driver from the Nvidia site.
Then you do install as following steps.

If you've enabled the restricted driver make sure you disable/deactivate it before doing the following.

1) Press Ctrl + Alt + F1. This will open up a terminal. You have to login with your username and password.

4) The installer will start. If it asks you whether you want to download a kernel interface it's probably best to say no (never worked for me). If you choose not to it will then ask whether you want to compile a new kernel interface. Say yes. Then it starts installing. After it finishes it will ask whether you want to run nvidia-xconfig to configure xorg.conf . SAY YES. Installation complete.

5) You can start gnome again by running:

sudo /etc/init.d/gdm start

So that's it installation complete and it should be working well.

Install and Config Virtualbox_2.4.x on Ubuntu 9.04 host (part 1)

Overview

I have just installed Ubuntu 9.04 and used as the primary OS. Ubuntu have been enormously developed in recently time with the support of developers. Ubuntu was integrated almost features which Window OS had, but there are some tasks the users need to use window such as control a scanner. I hope this features will be added on Ubuntu so far, however this disadvantage can be temporary tackled by using the above solution. Firstly, the users can install Virtualbox as an Virtual Machine on Ubuntu host. Secondly, create a new virtual machine in Virtualbox and install Window OS to use in some cases. Furthermore, the users can configure some add-on to use sharing Data between Linux host and window client. Here are some instructions in detail.
I. Download and install Virtual box
You need to download this software from website Virtualbox, then install it. However, i recommend that you do not do this manner because it is not convenient. I suggest that you should do as following steps:
1. Adding an CA into your "Software source" (Repository) by using terminal command (root mode)

wget -q http://download.virtualbox.org/virtualbox/debian/sun_vbox.asc -O- | sudo apt-key add -

2. from "System->Administration->Software Sources", selecting tab named "Third Party Software" , and click add button to type this text:
deb http://download.virtualbox.org/virtualbox/debian intrepid non-free
3. Reinstall or install
- for reinstall:
sudo apt-get remove virtualbox-ose virtualbox
- for new install:
sudo apt-get install virtualbox
or type this command:
sudo aptitude install virtualbox
4. Find your icon in Applications->System Tools->Sun VMx VirtualBox
or Accessory - > sun virtual box.
the above image is about Virtual box after installing and creating an new VM XP OS

My Introduction

Hi All, :)

I would like to introduce something about myself. My first name is Dong; however, you can call me Livvn as nickname. I had a fantastic childhood in Hue suburb where my little house opposed of a large field. I used to get up early and went through the field together with my friends. I could really have a the smell of grass and rice growing on the field while i was charmed by the gorgeous landscape of sunset. My childhood, adolescence went by smoothly and happily.

I have been in danang since the year 2001. It took me 5 years to accomplish graduated degree. I left university in June 2006 after receiving degree. I had a huge plan to promote myself and help many people; however, there was a pity that i could not apply my plan. At the moment, as a lecturer of IT faculty of Danang University of technology, i must continue to study and do research to get higher degree. I am under learning pressure so that i concentrate on studying and free worry about running my plan. I am sure that i never stop move on my prospect which i will keep going on.
I think the happiness of a person is that she/he has own forward motivation for clearly goals. I am thinking and finding the best solution with the support of my friends to identify my goals clearer and more detail.

I have some words to share with you whom read my introduction. I hope you will have enough brave and strong to pursuit your dream. One day, your dream will come true.
Be keep gong on.
Good Luck!
Dream of innovation.
Best regards,
