Big 5 Doomsday Scenario "2012"

While the end was not possible in the year 2012, only Allah knows, behind it, are five possible scenarios that could end human life in this world. Foreign Policy gives five possibilities that could be "the end" real. What else?
How did this happen? Objects from space have an impact on the earth all the time. Usually they are burned in the atmosphere. Tunguska event in 1908 in the Siberian forest with a blast of about 1000 times more powerful than the Hiroshima bomb had caused the damage of 2,000 square miles. Equal to the damage of a large metropolitan city.
How likely is it? Another large object hit the earth would have eventually, but not so sure. Every one million years, the object which hit the earth. According to NASA, the closest possible only in the year 2880.

2. Climate Disaster
How did this happen? Under worst-case scenario predicted by the International Panel on Climate Change, global surface temperature of Earth could increase by 4-5 degrees Celsius by the end of this century. Such a scenario would lead to increased sea levels up to five feet, flooding coastal areas, including many of the big cities of the world. Meanwhile, nearly a third of the planet could be desert and more than half will experience a drought.
How likely is it? According to the MIT global carbon levels currently at 380 parts per million, whereas the number was only 280 before the Industrial Revolution. Most scientists conclude that the impact of the disaster will begin to feel after going through the 450 level. Recent research by the National Aeronautics Oceanographic Administration shows that many impacts of climate change has not be changed.

How did this happen? Currently there are over 23,000 nuclear weapons in the world, and as many as 8000 in the operational and others are located at 2000 alert status and ready to be launched in a short time. Nuclear Doomsday has long been a popular subject for books and movies.
How likely is it? A study by ecologists at Rutgers University in 2007, found that the global nuclear inventory is still capable of destroying the global agriculture during the year causing famine for most of mankind.

4. Plague
How did this happen? Throughout history, evil has brought civilization to the level of the most rencah. Black Plague killed more than half the population of Europe in the Middle Ages. In 1918, an outbreak of flu killed an estimated 50 million people, almost 3 percent of the world's population, the impact of a much larger than the victims of World War I. Ebola virus has a mortality rate 90 per cent and so did HIV.
How likely is it? Treatment of disease has improved since 1918, but the disease is also more and more. Modern industrial farming techniques blamed for outbreaks of disease. More than 40 new viruses have emerged since the 1970s, including ebola and HIV. Biological weapons experimentation has added a new and just as disturbing complications.
5. Unknown
How did this happen? There are several theories of how human civilization ended. There is a natural: like the volcanoes that erupted as in Yellowstone National Park. Others are man-made: overpopulation causing a food crisis or the development of new technologies coincidence.
How likely is it? Sooner or later, the world will end. In about 5-8 billion years, according to astronomers' estimates, our sun will burn the hydrogen into helium and the sun will become a red giant hundreds of times from the current size, drag the earth to its inevitable destruction.
Five possible that only limited human invention. Allah scenario obviously much more unexpected. Resurrection may not happen in 2012, which is more important for us is to save his best deeds, because the big question that should always hang on our minds: where to live after this life?

Muttawifs... Making Hajj Easier

CAIRO — The Saudi government might manage hajj but a few number of young Muttawifs (hajj guides) strive to make the annual journey much easier for nearly three million Muslims. "We take control of the pilgrim from when he first puts his foot on the soil of Makkah," Imad Abdullah, a Muttawif, told Agence France Presse (AFP) on Monday, November 23. Muttawifs are deployed in the holy cities of Makkah and Medina to organize and help pilgrims.
Their main task is to make sure that people who have waited a lifetime to perform hajj, one of the five pillars of Islam, do that easily.
"We organize the shelter, food, transport, the rituals, and try to resolve any problems that come up," said Abdullah.
Every able-bodied adult Muslim -- who can financially afford the trip -- must perform hajj once in their lifetime.
Muttawifs also organize visits to important sites and help the pilgrims with their shopping trips so they can return home with gifts and souvenirs.
Knowing foreign languages is a particular asset for a Muttawif and many excel in the tongues of the region they handle.
Around three million pilgrims from over 160 countries are expected to perform hajj this year, which will climax on Thursday, November 26, when the faithful ascend Mount `Arafat.
While serving the pilgrims Muttawifs encounter many funny and difficult situations.
"It's magnificent," said Abdullah recalling many times when pregnant women whom he was accompanying gave birth during hajj.
"But it makes the job complicated, because we have to take them to hospital."
He also remembers the story of a pilgrim who was mentally unbalanced.
"But under the effect of the intense heat in Makkah and the spirituality of the place, he ended up recovering his senses."
Though a grueling job, thousands of young Saudis, both men and women, seek to become Muttawifs.
The job has proved lucrative with a Muttawif making from 800 to more than 5,000 dollars for a few days' work depending on his/her experience.
Helping foreigners who do not speak Arabic to navigate through the lengthy hajj ritual is an old business that remained undisciplined until the 1930s.
Then King Abdul Aziz bin Saud, the founder of modern Saudi Arabia, organized the families that controlled the business into six companies, each with rights to handle pilgrims from a specific region.
Abdullah's family, in the business for 150 years, is part of one of the companies.
"Our sons will inherit the job," said Abdullah, who has been specialized in helping Southeast Asian pilgrims for 30 years.

Change Background Colour of New Blogger Sidebar

A blogger commented that he could not find the sidebar color code in the template to change the background color of the sidebar. The CSS (Cascading Style Sheet) of every template is written different and if something is missing, all you need to do is to add the relevant missing part in.

For example, in the standard Blogger Scribe template, this is the section in the CSS (Cascading Style Sheet) for the sidebar:
#sidebar {
padding:8px 0;
word-wrap: break-word; /* fix for long text breaking sidebar float in IE */
overflow: hidden; /* fix for long non-text content breaking IE sidebar float */

There is nothing mentioned about background. So what I did was to add a single line

background: #FFFFFF;

(#FFFFFF is the hexadecimal color code for white) to that section, so that it became:

#sidebar {
padding:8px 0;
word-wrap: break-word; /* fix for long text breaking sidebar float in IE */
overflow: hidden; /* fix for long non-text content breaking IE sidebar float */
background: #FFFFFF;

You can see the result at Standard Blogger Scribe Template.

BTW, instead of using hexadecimal color codes like #FFFFFF, you can also use most names of colors like red, blue, white, etc. If you want to blend the color to the colors of the site, try typing the search term "colorpic" or "iconico colorpic" into the search box above, tick ( ) Web radio button and search, and I am sure you would see the link as the first result in the SERP (search engine result page) to download a very useful tool I use to get the color code of colors on any website. (I don't want to put too many outbound links as I understand outbound links can lower your PageRank).

I also find
Color Blender very useful if I want some "in-between" color or colors. If anyone is interested on how to use that site properly, just make a comment and I will do a new post on how to use it.

Have You Winterized Your Car Yet?

Trying to determine how bad the winter will be is close to impossible and counting the stripes on a wooly bear caterpillar is as helpful as watching your local weather forecast. Fortunately, Northeast Ohio hasn’t been bombarded by snow yet, but it’s just a matter of time before those chilly snowflakes start floating from the sky. Although you might think you have time to prepare your car for the winter, it’s important to get your car ready now.
Winterizing your car might be a foreign process to you, but if you take care of your car, it will take care of you. Gasoline as well as extra parts and labor for repairs are expensive, but if you follow the tips below, you can increase your mileage per gallon and preserve your car’s current parts for longer.

  • Test your battery when it’s nearing the end of its warranty. If you notice corrosion (rust or a white dust) on the battery terminals and cables, use a mixture of toothpaste, baking soda and water to remove it.
  • Examine your car's engine belt for cracks, frays and missing pieces. When you have a slipping belt, it prevents your battery from recharging properly.
  • Maintain a full tank of gas during the freezing weather. By running your gas tank down to the last drop before filling up, you risk the accumulation of moisture and ice in your fuel lines.
  • Check your air filter to see if it needs replaced. This is especially important in cars with a fuel-injected engine, because if the air filter is dirty, the sensor might call for more gasoline when it's really not needed.
  • Monitor your tires when the temperature drops, because they usually run low in cold weather. Don’t forget to make sure that your spare tire is filled up too.
  • Consider investing in snow tires. All-season radial tires do work well in snowy areas, but if you’re near the snow belt or are constantly commuting in the bad weather, snow tires will make your car a little safer.
  • Change your antifreeze according to the manufacturer’s specifications, because this liquid shields your vehicles cooling system.
It’s easy to hop in your car and go without checking any of these issues, but your neglect will catch up with you eventually. Keeping tabs on your car increases your safety, and it also improves your mileage and your car's longevity.

A Dead-Simple Masthead Amplifier

Decided to take the plunge and get into digital TV? For most people, it's simple - just plug the new TV or set-top-box into your existing antenna. But for many, the old TV antenna and cable just won't be up to it. HereÂ’s a new kit from Oatley Electronics which could solve your digital woes . . .

About now, with new HD Digital “Freeview” channels starting up, many people are investing in digital TV technology.
Whether that means a new, you-beaut flat-screen TV with all the bells and whistles or perhaps a digital TV set-top-box used in conjunction with your old faithful telly sitting in the corner, you should be getting a host of new TV channels, right?
Umm, no. At the time of writing there are only ABC2, SBS2 and OneSport even worth mentioning. One or two more are imminent.
But the Freeview ads promised what, 20+ new channels? That may happen in the future but so far, the other (commercial) networks digital offerings are nearly identical to their analog offerings. And as we all know, that isn’t much of an offering.
Incidentally, Freeview have recently been ordered to change their “misleading” advertisements . . .
Programming aside, many viewers have found another slight problem with digital TV: they can’t view it!
This is usually limited to areas where the analog TV signals have been marginal anyway but the problem certainly manifests itself more with digital. With analog, your picture might be noisy or snowy but at least it’s there and sort-of watchable.
With digital, the dreaded “digital cliff” means your signal is either there or it isn’t. Unlike analog, with digital there’s virtually no “grey area”.
Just as importantly, the digital cliff can also rear its ugly head when the signal levels are too strong.
We’ve all heard the stories about people living close to the transmitters who didn’t even need any antenna to receive TV signals . . . well, many of these are in for an unpleasant surprise when they try to install digital.
The digital cliff is more like a digital plateau: there is not enough signal, so you get nothing; there is enough signal, so you get reception; and there is too much signal, so you get nothing. It’s relatively simple to attenuate the signal if you get too much, so we’re more concerned with not enough.

Green Computer with Biodegradable Peripherals

Imagine this: you buy a new computer monitor, take your old one and just bury it in the garden. 3 years later the monitor has biodegraded and your prized tomatoes are growing better than ever. The world's first 100% biodegradable computer components have arrived from MicroPro, a company based in Dublin, Ireland who produces eco-friendly computers, keyboards, mice and flat-panel monitors. The company, established in 1992, has just 17 engineers but has made a big impact with their innovative designs.The product is named iameco, and is the brainchild of MicroPro's Managing Director, Paul Maher.
 Toxic Waste
Maher's journey to create the world's first truly green computer began 15 years ago when he watched a little girl disassemble a computer with a blowtorch. "She was about five years old and was recycling the lead. She was bare foot and didn't even have a mask on. Her legs were speckled with burn marks. From then on I started working on the green computer," he says. Maher was annoyed at the short lifecycle and disposable nature of computers. Worse yet, manufacturers commonly use hazardous materials such as brominated flame-retardants, PVCs and heavy metals like lead, cadmium and mercury.

"I have been in the computer business for close to two decades and in that time, I have been aware of the astonishing waste in the PC industry. With iameco computers, we have cut this waste out, and have built beautiful, high-specification computers without any of the toxins that have traditionally been used in computer manufacture. Not only has great care gone into the outside of these machines, we have put just as much effort into ensuring that iameco computers are powerful enough for everything from 3D gaming and design, to simple e-mail and word processing, says Maher.

Modular Design
The designs are ascetically stunning and easily upgradeable. The computers modular design is what makes them different from other computers: our computers are updatable, upgradeable, reusable, recyclable and at the end of the life of them we can replace the main board and start all over again. You can remove individual parts and reuse them or replace them with more modern parts. The life span of these computers is 7-10 years, up to 3 times the lifespan of an average computer. The computers are a third smaller than average computers on the market, requiring less energy to manufacture. They require less energy to run as well: "this runs on low power - 35W in normal mode, whereas other computers use 300W, and 4W in standby mode, says Maher. Many of the keyboards, mice and monitors have a wood based frame and are made from the waste product of the pulp industry in Europe. These materials are 100% biodegradable. Other components are made of wood harvested from sustainable sources: beech from Germany, ash from the USA, and dark wood from East Africa. You can bury them in the ground and they will go back into the soil within 3 years. The use of reusable materials and recyclable packing results in a zero waste product. The product is very close to achieving the European Eco label, a world first.

Under the Hood
These computers aren't just eco-friendly; they look stunning and pack a powerful Intel Core 2 processor under the hood. Most are customizable and will ship internationally. Prices range from €699 ($914US) -€1599. Many iameco monitors double as a television; they even have 40inch flat TV/monitor and a 32inch flat HDTV TV/monitor. You can check out the whole range of products and get more information on their design by visiting

7 Cloud Computing Myths Busted

What is it about "the cloud" that has people, well, getting their heads up in the clouds over it? Almost no other IT innovation in recent memory has engendered this much enthusiasm—and furor, and confusion, and outright misunderstanding.

The cloud isn't exclusively a cure-all or a calamity in progress; neither is it a savior or sinner. It's a new tool for solving emergent problems, and like every new hammer in someone's hands it can make everything look like a nail.

In this piece we'll examine many of the current myths—good, bad, and bogus—about cloud computing. Many are borne by simple ignorance or inexperience. Others are legitimate criticisms in the guise of gripes. And some are entirely too on target, and need to be nipped in the bud by prospective cloud-creators before they get bitten by them.

1. Compatibility Issues
Myth: Cloud computing is too proprietary.
At present, no two clouds are alike—both in nature and in IT. Amazon’s cloud platform is nothing like Google's, which is nothing like Microsoft's, which is nothing like and you can insert the name of any other up-and-coming cloud provider here.
And yet "proprietary" has not proved to mean ‘useless’—not by a long shot.
Think back to the early days of the personal computer. The first wave of PCs were all from different makers, used different hardware, and weren't remotely cross-compatible. Programs written for the Apple II weren't assumed to have any interchangeability with the Atari, the Amiga, or even the IBM PC itself.

What few common platforms that existed—e.g., CP/M—were largely for the sake of porting and running existing applications to those platforms, rather than for creating a crossbar of compatibility among them. None of this stopped a remarkable amount of development from taking place—and the various platforms were able to compete heavily based on their differences.

Granted, the situation today is totally unlike that. People expect a great deal more cross-compatibility as a matter of course—between devices, between applications, between platforms and environments. What's most proprietary about the platforms isn't so much the way they work on the inside as the fact that talking to each cloud, getting data into and out of each cloud, and managing functionality within each cloud are all done differently.

The proprietary nature of the first wave of cloud computing platforms is, for lack of a better way to put it, a necessary evil. And maybe even not all that evil in the first place, when it grants you access to platforms like Linux ( and languages like Python (Google), which on their own terms are as open as they get. Things could be made less proprietary outside clouds and among clouds, although odds are the standards that will exist between clouds will develop more as a consequence of what people are actually using (e.g., EC2) rather than something drafted in the abstract.

Nexus, The Latest User Interface from Sony Ericson

With an attractive UI display can determine how much the users at home using the existing devices. And of course there is a link between the presence of the device with a display dihadirkannya UI.

So did it with what is experienced by Sony Ericsson, the article after the Sony Ericsson brings a great device like mobile device Xperia Android-based X10, now is the time for presenting a user interface display to be juxtaposed New with these devices.

View the latest SE UX platform named Nexus. Nexus itself was introduced first time in the Android based mobile device Xperia X10. And not closed the possibility of the same thing will happen to the other Sony ericsson devices are planned to be realized in 2010 and 2011 that will come.

User Interface applications include signatures, charts display the latest UI and various levels of integration of services. Associated with the Sony stated that if the platform is designed for operation with the Android operating system and other platforms, although not specifically.

Sony Ericsson will collaborate with his colleagues, developers and operators to mengoptimisasikan and mengkostumisasikan Nexus itself. The aim of Nexus itself is only able to assist and manage all data, media and communication and how to find the data and that based on recent media habits and preferences of the users so far.

Greenpeace challenges ASEAN to get serious about climate threat

Hua Hin, Thailand — Greenpeace today challenged ASEAN leaders to demonstrate collective leadership to protect Southeast Asia’s 850 million people from the debilitating impacts of climate change by committing to zero deforestation and low carbon development, and to force the leaders of the developed countries to agree to deep and binding cuts in global greenhouse gas emissions at the UN Climate Summit in Copenhagen in December.
Volunteers from the environment organization made their way to the Dusit Thani, venue of the ASEAN Summit, pushing a gigantic “earth ball” with the message “ASEAN leaders: U turn the Earth.”

“ASEAN citizens are already reeling under catastrophic impacts of climate change, as was made brutally clear by Typhoon Ketsana last month.  Yet, instead of recognizing their enormous obligation to safeguard the region, the ASEAN appear to still be in denial over these threats, expressing only token concern when catastrophe strikes but failing to match the same concern with real action and leadership to avert the climate crisis,” said Tara Buakamsri, Greenpeace Southeast Asia Campaign Manager.

“It is critical that ASEAN member states, collectively and en bloc support the completion of a strong climate deal in Copenhagen in December, and as a sign of their contribution to the needed emission reduction targets, announce zero deforestation and prioritize options which will strategically liberate our societies from the treadmill of carbon intensive and fossil-fuel based systems," he added.

The ASEAN has only very recently started tackling climate change and its statements on the issue so far have been very general and lacking in clear action plans.  In December’s climate summit, the world has a historic opportunity to step back from the brink of catastrophic climate change.  The burning of fossil fuels such as oil, coal and gas is not the only cause of global warming.  Tropical deforestation is responsible for about 20% of global greenhouse gas emissions, a share more than that of all the world’s trains, planes and cars put together.

In order to achieve a significant deviation from business as usual growth of emissions in developing countries, action on forest protection is urgent.  Together with other groups, Greenpeace has developed a proposal showing that tropical deforestation in countries like Indonesia can be halted by 2015.

“We hope that given the converging interests of Southeast Asian countries on the issue of forest protection and climate change, the ASEAN would support our call for industrialized countries to provide at least USD 40 billion annually by 2020 to support efforts to halt deforestation in developing countries, as an immediate step in mitigating climate change,” said Zelda Soriano, Greenpeace Southeast Asia Political Advisor.

The Greenpeace activity is among the 4,457 activities in 172 countries for today’s Global Day of Action on climate change

Amikom Speech Contest 2009

In the name of Allah, Most Gracious Most Merciful
Assalamualaikum wr.wb

Good Morning

The honourable Adjudicators
Ladies and gentlement,

First of all I’d like to introduce my self My name is Yuni Ardita Sari Dewi. I’m from Bachelor Degree in Information Technology at 4th semester in class A.
Allow me to commence this occasion by saying that it is a great honour for me to have an opportunity to deliver a speech before the intellectual community of audience. And I’d like to thank “Amikom English Club” for such moment. The title of my speech is “ Information Technology makes Education so simple and flexible”.

Information Technology is part of technology for arranging, manipulating, organizing and processing data in many kinds of way to get some information  which is accurate, relevant   and   just in time. Information Technology have a dominant sector in the world that used to support establishment in business, education, privacy, government and also to make decisions. This technology consist of   computers for organizing data and networking system to connecting all over computers in the world

Growth of Information technology can improve performance and enable various activity can be executed swiftly, precisely and accurate, so that finally will improve productivity. Growth of Information Technology show the popping out of various activity type being based on this technology, like e-commerce, e- education, e-government, e-medicine, e-laboratory and other, which is that all things have electronics based.

The main point I’m going to make concerns that Information Technology gives us a lot useful especially in education. In the wonderful computer age, globalization can improve transition from conventional education to flexible education. For example, in France, there is “FLEXIBLE LEARNING”. It’s remind us, in beginning of 1970, Ivan Illich found that education in the future , extremely, the teacher will not teach students in class like we are doing now, but education will determined by networking system, that will allowed us to have interaction and collaboration with our lecture closely, not school buildings. Education in the future, will be open source, easily access, more discipline, and also enhance productivity for  the student itself.

Tendency  of Indonesian education in the future:
  1. Education development by long distance learning. It’s makes student easier to take education in long distance.
  2. Library and instrument of education (like teachers and laboratory) have a change function become information source more than stack of books in the cupboard.
  3. Using Interactive Information Technology devices, like Multimedia CD ROM to replaced TV and video.
I wish it’s it will be happen in Indonesia..

In concluding, I would like to say: Information Technology had produced the role of innovations in the globalization and given our education become increasingly more simple and flexible. So,my suggest,we have to be wise about Growth of Information technology, because using and advance technology it’s our duty, as a student.
I think that’s it enough. I beg your pardon if I make any mistakes. Thank you very much.

Intel, Processors Environmentally Friendly

    Intel Corp.. developing a new microprocessor technology with Hi-K materials, ie materials with high dielectric constant values, and free Pb (lead). Meeting representing the dielectric constant of electrostatic flux in a material when given electric potential. Dielectric constant is a parameter in a variety of electronic devices, especially transistors. The higher the K value of the capacity of the larger transistor. So when is off, the current still came out very little while when you're on, the flow comes out very large. Therefore, the Hi-K material then the processor performance will improve. 

   Then the lead. Lead has long been used in the manufacture of the processor as an alloy in Soldering process. But the lead is one of the heavy metals and hazardous materials that can harm human and environmental damage. Therefore the use of lead should not happen, so to look for solutions to overcome the problems of lead. Research Intel Corp.. find a replacement lead, the tin - silver - copper solder (lead free). The benefits of these materials is leburnya points higher than lead, which is 220oC, the value of increased strength, and also environmentally friendly. Therefore, the Pb-free this can improve the performance of a processor and also friendly to the environment. Remembering the ultimate goal of technology, namely to save life on earth, not shorten the life of the earth.

Greenland ice sheet

The Greenland Ice Sheet is a vast body of ice covering roughly 80% of the surface of Greenland.
It is the second largest ice body in the world, after the Antarctic Ice Sheet.
The ice sheet is almost 2,400 kilometres long in a north-south direction, and its greatest width is 1,100 kilometres at a latitude of 77° N, near its northern margin.
The ice sheet, consisting of layers of compressed snow from more than a hundred thousand years, contains in its ice today's most valuable record of past climates.
In the past decades, scientists have drilled ice cores up to three kilometres deep.
With the ice cores, scientist have obtained information on (proxies for) temperature, ocean volume, precipitation, chemistry and gas composition of the lower atmosphere, volcanic eruptions, solar variability, sea-surface productivity, desert extent and forest fires.
This variety of climatic proxies is greater than in any other natural recorder of climate, such as tree rings or sediment layers.
The Greenland Ice Sheet has experienced record melting in recent years and is likely to contribute substantially to sea level rise as well as to possible changes in ocean circulation in the future..
