Information technology in Indonesia

Jakarta: Indonesia must it was thought straighten out technological education, including information technology, since early to change from the agricultural nation to the based country the industry.

Wahidin Wahab, President Robot the Olympics Committee Indonesia (ROCI), said Indonesia was left five to 10 years in the technological field from our neighbouring country like Malaysia, the Philippines, Singapore, and Vietnam.

"When our neighbouring country was competing to level itself to the country that had the technological capacity that was competent like Japan, Indonesia precisely still in the beginning stage in developing this technology," he said in the seminar made Robot find it easy in implementation gaps of the exhibition of the Bazaar clouds computer in JCC Jakarta, last week.

According to him, the technological gap became one of the factors why most Indonesian communities experienced technological retardation. The command or access to technology only was obtained by a small number of people who had the fund and the adequate cost. That caused technological knowledge to be not equitable.

A Riza Wahono from Creative foundation said the lesson that was based on technology must be made pleasant and caused curiosity from the student. The studying concept must be changed in a playing manner while studying, with that the student will more be attracted by the world of technology.

Get Yourself Started In Blogging

As of September 2007, more than 106 million blogs have been tracked which makes one wonder just what blogging is.Blogging is that wonderful world where you can write your personal thoughts about what you think on any subject imaginable, whether good or bad, with or without anonymity, although in reality anonymity really doesn’t exist when it come to the Internet. Your website, your email has an ISP address which is easily traceable to any given computer.

In general, blogs are articles you write and post on the web for the entire world to see. Your blog puts you, your thoughts in the forefront, which lets others see your brilliance or idiocy. You can have your own website dedicated to your thoughts, or you can respond to a particular article that has been written which allows you to voice your opinion about the subject or article, although use tact when responding. Most news media allowing you respond to a written article requires you to provide a valid email address in order for you to make a comment.

Most subscribers to the Internet post there blogs on personal web pages or websites their ISP provides. Other bloggers post their comments on the multitude of websites available for posting their thoughts, usually indexed by subject. To find a blog site, simply type “blog/s” in any search engine and behold you will find thousands of blog sites you can read or post.

Methods for blogging vary which you should consider before doing any posting. Blogging in response to a particular article, as well as posting on dedicated blog sites are permanent blogs, in that they can not be changed once posted. With that in mind, you really need to think about what you want to say before posting your thoughts. It’s somewhat like making a comment, once spoken it can’t be undone.

The other side of posting on an open blog site is the libel issue. At present, blog sites are not libel for what you say, so use caution when blogging.

The other method of blogging is to have your own website or page where you write your own blog. Using this method, you can edit your blog, write about another subject or simply delete the blog entirely. This method in my opinion is perhaps the safest method of blogging, but there is a caveat to this method. When you write something on your computer using a word processor and save the document, even if you delete the article, or document, it still resides on your computer and unless you completely reformat or destroy the hard drive, it remains on you computer forever. If someone wants to prove you wrote the article, with the proper software they can retrieve it.

You may wonder if blogging is without peril. That depends. If you are blogging about your Aunt Tilly’s super fruit cake recipe, you’re safe, but if you’re blogging about a politician, an organization, the government, religious leaders, a company, an individual, you need to be careful about what you have to say, as you just might be libel. Presently, in the US, the courts are undecided about blogging, weighing in on the free speech side of the argument, however; individuals have been imprisoned and/or fined for their blogs.

To be safe when blogging, it’s important to use the correct adjectives, or follow the method the news media use when writing an article. Words like; alleged, subject to, suspected of, and the like may keep you out of trouble. Although, innuendos you make can been seen as an attack, an accusation, by some very sensitive people and they just might decide to take action against you.

Even when using safe words, that doesn’t mean you’re not going to suffer the consequences for your big mouth. Many states have what is known as; “The Right To Work Law,” which simply means employers can fire an employee for any reason, or for no reason. Individuals have been fired from their jobs for posting blogs about their company.

Many blogs are instructional in nature from how to grow a tree, wash a cat to building an explosive device. Here again you need to be careful. Those blogs about explosive devices just might cause a visit from a federal agency. Unfortunate as it is, when it comes to blogging, “Big Brother Is Watching!”

How is PageRank calculated?

To calculate the PageRank for a page, all of its inbound links are taken into account. These are links from within the site and links from outside the site.

PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))

That's the equation that calculates a page's PageRank. It's the original one that was published when PageRank was being developed, and it is probable that Google uses a variation of it but they aren't telling us what it is. It doesn't matter though, as this equation is good enough.

In the equation 't1 - tn' are pages linking to page A, 'C' is the number of outbound links that a page has and 'd' is a damping factor, usually set to 0.85.

We can think of it in a simpler way:-

a page's PageRank = 0.15 + 0.85 * (a "share" of the PageRank of every page that links to it)

"share" = the linking page's PageRank divided by the number of outbound links on the page.

A page "votes" an amount of PageRank onto each page that it links to. The amount of PageRank that it has to vote with is a little less than its own PageRank value (its own value * 0.85). This value is shared equally between all the pages that it links to.

From this, we could conclude that a link from a page with PR4 and 5 outbound links is worth more than a link from a page with PR8 and 100 outbound links. The PageRank of a page that links to yours is important but the number of links on that page is also important. The more links there are on a page, the less PageRank value your page will receive from it.

If the PageRank value differences between PR1, PR2,.....PR10 were equal then that conclusion would hold up, but many people believe that the values between PR1 and PR10 (the maximum) are set on a logarithmic scale, and there is very good reason for believing it. Nobody outside Google knows for sure one way or the other, but the chances are high that the scale is logarithmic, or similar. If so, it means that it takes a lot more additional PageRank for a page to move up to the next PageRank level that it did to move up from the previous PageRank level. The result is that it reverses the previous conclusion, so that a link from a PR8 page that has lots of outbound links is worth more than a link from a PR4 page that has only a few outbound links.

Whichever scale Google uses, we can be sure of one thing. A link from another site increases our site's PageRank. Just remember to avoid links from link farms.

Note that when a page votes its PageRank value to other pages, its own PageRank is not reduced by the value that it is voting. The page doing the voting doesn't give away its PageRank and end up with nothing. It isn't a transfer of PageRank. It is simply a vote according to the page's PageRank value. It's like a shareholders meeting where each shareholder votes according to the number of shares held, but the shares themselves aren't given away. Even so, pages do lose some PageRank indirectly, as we'll see later.

Ok so far? Good. Now we'll look at how the calculations are actually done.

For a page's calculation, its existing PageRank (if it has any) is abandoned completely and a fresh calculation is done where the page relies solely on the PageRank "voted" for it by its current inbound links, which may have changed since the last time the page's PageRank was calculated.

The equation shows clearly how a page's PageRank is arrived at. But what isn't immediately obvious is that it can't work if the calculation is done just once. Suppose we have 2 pages, A and B, which link to each other, and neither have any other links of any kind. This is what happens:-

Step 1: Calculate page A's PageRank from the value of its inbound links

Page A now has a new PageRank value. The calculation used the value of the inbound link from page B. But page B has an inbound link (from page A) and its new PageRank value hasn't been worked out yet, so page A's new PageRank value is based on inaccurate data and can't be accurate.

Step 2: Calculate page B's PageRank from the value of its inbound links

Page B now has a new PageRank value, but it can't be accurate because the calculation used the new PageRank value of the inbound link from page A, which is inaccurate.

It's a Catch 22 situation. We can't work out A's PageRank until we know B's PageRank, and we can't work out B's PageRank until we know A's PageRank.

Now that both pages have newly calculated PageRank values, can't we just run the calculations again to arrive at accurate values? No. We can run the calculations again using the new values and the results will be more accurate, but we will always be using inaccurate values for the calculations, so the results will always be inaccurate.

The problem is overcome by repeating the calculations many times. Each time produces slightly more accurate values. In fact, total accuracy can never be achieved because the calculations are always based on inaccurate values. 40 to 50 iterations are sufficient to reach a point where any further iterations wouldn't produce enough of a change to the values to matter. This is precisiely what Google does at each update, and it's the reason why the updates take so long.

One thing to bear in mind is that the results we get from the calculations are proportions. The figures must then be set against a scale (known only to Google) to arrive at each page's actual PageRank. Even so, we can use the calculations to channel the PageRank within a site around its pages so that certain pages receive a higher proportion of it than others.

You may come across explanations of PageRank where the same equation is stated but the result of each iteration of the calculation is added to the page's existing PageRank. The new value (result + existing PageRank) is then used when sharing PageRank with other pages. These explanations are wrong for the following reasons:-

1. They quote the same, published equation - but then change it

from PR(A) = (1-d) + d(......) to PR(A) = PR(A) + (1-d) + d(......)

It isn't correct, and it isn't necessary.

2. We will be looking at how to organize links so that certain pages end up with a larger proportion of the PageRank than others. Adding to the page's existing PageRank through the iterations produces different proportions than when the equation is used as published. Since the addition is not a part of the published equation, the results are wrong and the proportioning isn't accurate.

According to the published equation, the page being calculated starts from scratch at each iteration. It relies solely on its inbound links. The 'add to the existing PageRank' idea doesn't do that, so its results are necessarily wrong.

What is PageRank?

PageRank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page's importance from the votes cast for it. How important each vote is is taken into account when a page's PageRank is calculated.

PageRank is Google's way of deciding a page's importance. It matters because it is one of the factors that determines a page's ranking in the search results. It isn't the only factor that Google uses to rank pages, but it is an important one.

From here on in, we'll occasionally refer to PageRank as "PR".

Not all links are counted by Google. For instance, they filter out links from known link farms. Some links can cause a site to be penalized by Google. They rightly figure that webmasters cannot control which sites link to their sites, but they can control which sites they link out to. For this reason, links into a site cannot harm the site, but links from a site can be harmful if they link to penalized sites. So be careful which sites you link to. If a site has PR0, it is usually a penalty, and it would be unwise to link to it.

New Hope for Domain Parking

by: David Doggett

Domain parking has had a bit of a bad reputation, and rightfully so. Most parked domains are setup with a domain registrar and they are the ones who end up making most of the income from clicks on your parked pages, that is, if your parked page gets any clicks at all. In truth, the domain registrars are likely only interested in making money from your domain name registration.

I have been intrigued with the domain parking concept however was discouraged until recently with the potential of parking my domains. It is true, almost all parked pages are shunned by the major search engines because they lack any quality content and are simply filled with ads. Simple logic told me that if the search engines are not interested at all with parked pages filled with ads, and this means the chances of people finding my parked pages is slim to none.

Thankfully there is new hope for parking domains with rich content parking systems, for example the one I now use, WhyPark (http://cyberflash.whypark.hop.clickbank.net/). These domain parking systems don't just set you up with a page full of ads and forget about you, they provide you with simple tools that let you create rich content websites full of relevant articles that search engines love. This is the most exciting development in domain parking history because it means anyone can create a quality web site containing your own advertisements that you earn all or most of the income from.

This revolution in domain parking opens the doors for anyone interested in creating powerful websites and capitalizing on their income potential.

While it is possible to invest just twenty minutes of your time setting up a domain with one of these rich content parking systems, the more time and effort you invest in promoting your domain, the more traffic your domain will receive in turn increasing your domains earning potential.

Variations Of Software Programs

Consumers are enthralled by the software installed in electronic devices because these programs allow them to be more productive and provide them with a source of entertainment that is suitable for every member of the family. Some electronic devices will not work at all without the software installed, and others work better because the software programs have been added since the device was bought.

People are more familiar with the software programs that run their personal computers, but other digital devices are equipped with software. The operating system software is the controlling force behind all computer operations, This software allows the user to perform independent tasks using word processing software programs, or includes software that will allow the user to complete complex mathematical calculations using formulas in spreadsheet formats.

The operation of this type of software is independent of any other type of custom software that has been installed on the computer. Many computer users must install software that allows them to view videos and graphics. These software programs are easy to download but will require update to be installed from time to time to keep the software program running smoothly.

The software updates are written with scripting software that simplifies updates by creating screens that are presented in an easy to understand language that requires the user to click a few buttons and step back while the software does the rest of the installation on its own. Other software is embedded into the installation program that will notify the computer user that the installation is complete. In most cases, the computer software will require that the user restart the system for the changes to go into effect.

Some customized software programs will be created for businesses to track inventory or provide a certain service to a client or the public at large. Some computer operating systems work on the Windows platform and other software program are open source and can be edited by users who know the coding used in the software programs. These programs can be modified by each user and uploaded to the site where it was obtained so that other users can benefit from the changes that were made.

People prefer to use open source software because it is available for download through internet websites. The open source software is considered freeware and is the product of computer users who have a talent for creating programs that enhance productive tasks found in other software or the software could be scripts that make mundane tasks tolerable and easier to complete. Some programming artists create freeware to establish a web presence and build a business from software popularity.

The software programs installed on electronic devices allow people to connect to the internet and the user will have all the tools and storage space required to download files from a computer at work. The PDA devices contain software that will also allow users to check email and store it for future reference. Some personal digital assistants are equipped with software that allows people to access maps and obtain directions to a desired destination.

Holiday Facial Fitness

by: R. Forrest-Young

It’s the time of year when the weather has changed and you’re busy running around, caught up in the hustle and bustle of the holiday rush. Along with having parties and making sure things around the home and office are filled with plenty of holiday cheer, you continue with your normal chores of paying bills, helping with homework, attending school functions and household upkeep. You’re probably doing a lot more in the day and getting a lot less sleep at night. Needless to say, this creates a lot of wear and tear on your mind, body and face. Yes, your face!

It’s no secret that added stress and less rest can cause you to feel and look worn out. You may have found that your face is starting to reveal signs of holiday fatigue. Puffiness and dark circles under the eyes, as well as a change in texture and clarity of your skin from lack of adequate rest, cold weather and wind, can put a damper on your seasonal celebrations. You need facial rejuvenation and you need it now!

The fastest, easiest and cheapest way to get back your facial glow or achieve a glow that you never had is by facial stimulation and massage. This technique has worked wonders on countless faces across the globe and was actually part of the beauty regiments of many ancient civilizations. What’s even better is that this is something you yourself can do for free. You don’t have to go to some doctor for surgery or injections nor do you have to go to a massage parlor or salon.

Studies show that stimulating your face with certain patterns of finger tapping and massage improves skins clarity and texture, prevents and reduces wrinkles and breakouts as well as reduces swelling. What you are doing is stimulating and waking up cells that have become dormant beneath the skins layers. This produces a lifting effect and promotes a firm and supple face. You are also unblocking and clearing clogged cells which increases the blood flow and circulation, thus, giving you a glowing and refreshed face in a matter of days. A noticeable improvement is often seen after the first day. Experts have said it restores a lost youthfulness to the face and can even give the appearance of having a facelift.

Facial stimulation and massage should become a part of your daily beauty routine during the holidays and everyday. It’s fast, free and easy, yet it yields great results. Try it and you’ll never have a dull face again.
