How does google work?

A quick type of letters and voila! The web page you want is right there. However , how exactly does Google works? How does the find the web page you are visiting now? Everyday Thousands of new websites are created so how does Google put them into their database?


Firstly, it has the evil Googlebot, Google’s Web Crawler!
















Googlebot is well, a bot which searches the web pages. It downloads them and sends them to google's huge database index. Googlebot consists of many computers requesting and fetching pages much more quickly than you can with your web browser. In fact, Googlebot can request thousands of different pages simultaneously. To avoid overwhelming web servers, or crowding out requests from human users, Googlebot deliberately makes requests of each individual web server more slowly than it’s capable of doing.


Google also learns of new web pages through their add page site www.google.com/addurl.html , by typing your website in here Google will be notified off your new web page and it will be linked on Google.


Also the Google indexer database doesn’t index common words such as the, is, on, or, of, how, why, as well as certain single digits and single letters. These words are so common that they do little to narrow a search, and therefore they can safely be discarded. The indexer also ignores some punctuation and multiple spaces, as well as converting all letters to lowercase, to improve Google’s performance.

Google also claims in their website that they have two types of technology to make searches faster, PageRank and Hypertext - Matching Analysis.

From google website :

PageRank Technology: PageRank reflects our view of the importance of web pages by considering more than 500 million variables and 2 billion terms. Pages that we believe are important pages receive a higher PageRank and are more likely to appear at the top of the search results.

PageRank also considers the importance of each page that casts a vote, as votes from some pages are considered to have greater value, thus giving the linked page greater value. We have always taken a pragmatic approach to help improve search quality and create useful products, and our technology uses the collective intelligence of the web to determine a page's importance.



Hypertext-Matching Analysis: Our search engine also analyzes page content. However, instead of simply scanning for page-based text (which can be manipulated by site publishers through meta-tags), our technology analyzes the full content of a page and factors in fonts, subdivisions and the precise location of each word. We also analyze the content of neighboring web pages to ensure the results returned are the most relevant to a user's query.

Thanks For Your Kind Attention.

Bits and Bytes

The two terms of "bits" and bytes" are commonly used computer terms.
Many people tend to mistake these two terms. They do not mean the same thing.
This is a scenario of a way how these two terms are mistaken.

SCENARIO

Tom has an enquiry about his internet connection speed and decided to call up his Internet Service Provider(ISP)

Tom: Hello there. I am not sure why I can't reach the maximum speed for my broadband internet service when I download. What is the problem with you guys?
ISP: I am sorry, but what is the issue?
Tom: I had just signed up for the 10Megabyte per second broadband service. Why is it that the maximum speed when I download is only about 1.25 Megabyte per second?
ISP: I am sorry sir, but I think you have been mistaken. We do not provide internet service at a speed of 10megabyte per second, but we do provide a 10megabit per second one.
Tom: ??? Whats the difference? Don't try to scam me!
ISP: Bytes are denoted as a capital letter B, but bits are denoted as the small b.
Tom: !@$# Stop B 'ing around. I'll find out myself! You dumbass! Don't try to scam me of my money! I am going to complain you to the ministry!

Tom slams the phone down.

This is the common confusion people space.

For now, let me clarify your doubts.
Bits usually refer to the data transfer rate, while bytes mainly refer to the storage capacity of a certain media.

Conversion between bits and bytes are as follows.

1byte(B)=8bits(b)
1megabyte(mB)=8megabits(mb)
1gigabyte(gB)=8gigabits(gb)

So therefore, if you have signed up with your ISP for an 8mbps broadband plan, you would only expect a download speed of 1mBps.

For example, this is showing downloading rate in bytes. -windows downloader.
Note that the byte is denoted as capital letter "B".














While here, the transfer rate is in bits, denoted by the small letter "b".














There,we had bits and bytes explained.

Software Review: Audacity

Audacity

The Free, Cross-Platform Sound Editor

Audacity is a audio editing software, which at the same time allows you to record audio in 1 or even more channels. Its simple, and all you need is just a microphone to record audio, and speakers for playback!

It is supported to open .mp3 files format, together with wav, ogg vorbis and also AIFF.
I would recommend anyone who wants to cut songs to set as ringtones to use this software as it allows you to export in .mp3 format too. However, for that you need an additional free download of the Lame MP3 encoder.
Audio editing and audio format converting is made easy. Download your copy of Audacity free now!

Click here to download.

It supports all platforms from windows to linux and mac.

Best of all , its free!

Software review : CC CLeaner.

As quote from www.ccleaner.com "CCleaner is a freeware system optimization and privacy tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. But the best part is that it's fast (normally taking less than a second to run) and contains NO Spyware or Adware! :) "

This software is great for removing unwanted or extra files and to clear up your system. It is far superior then windows disk cleanup. As it does not create fragments and also searches far more quicker and faster. It is a very very good programe also to remove traces of internet site you visited and cookies and such. However this programe does not have a 'Unwanted files compressing system' like windows disk cleanup. It also help you to due with issues such as fragmented links and files.

The layout of this software is also easy to use and it has a simple plain layout. A checklist is also present for what you want and do not want to be removed.

This programe also has the 'Analyse' function which tells you what you would removed and the amout of space which will be freed. It evens give you a case-by-case analysis of the different types of files.

Download CC Cleaner free at http://www.ccleaner.com/download

On the whole i would give it a 8.5/10
Style 6.5/10
Ease of use 9.5/10
Funtionality 8/10
Speed 9/10

Connecting any audio output to a radio set

Have you ever wanted to play your mp3 songs from your mp3 player to your car stereo system? How about amplifying your mp3 player to a radio speaker?
You need not think more. Technology never fails as I always say.
It is possible for you to do it.


All you need is a simple FM audio transmitter to do the work.
This device allows you to create your own electromagnetic waves embedded with audio information into a certain radio frequency. This way, as you switch your radio receiver into that frequency, you will be able to hear audio you transmitted. Easy and inexpensive.
I got mine at Cyberactive computers at WestMall some time ago, which cost me S$9.90. Although audio quality goes down a little, but its better than nothing. For better quality, perhaps some other better brands like Belkin can do it better.

Windows Vista VS Ubuntu Studio (Boot Time)

This is our very first video review.


Using two almost identical devices to test out the boot time for the two different operating system makes the results even more accurate.

Note that both Ubuntu Studio and Windows Vista are not modified to make them boot any faster. They are original versions of each OS.

Windows Vista boots up a few seconds faster than Ubuntu Studio, even though the typing in of username and passeword for ubuntu studio is just 2 seconds.

Windows Vista may had booted up faster than Ubuntu, but I think a few more seconds would not cost users much. Also, Ubuntu has many other privileges over Windows Vista as well.(Other reviews will be posted on that)

CCCP- The Combined Communtity Codec Pack

It is recommended for you to uninstall all other codecs before installing CCCP.

Mac Donald Review!

This is a review of a mac for mac computers,firstly this is a picture of a mac ^.^

Now what are the main differences between a mac and windows OS?

Windows users have experienced the poor stability that comes with Windows. Many users have to restart their computer at least once a day. Also, when a program does not response, the entire computer usually quits functioning and hangs. However the Mac OS is a lot more stable and does not frequently have errors.

Also Mac and Windows are typically not compatible with each others except if you have installed freeware programes to allow windows documents to be used on a Mac. As for why, Mac and windows are rival (duh).

Not only that but the programmes in Mac are definitely better than in Windows , how can windows media player/movie maker compare to final cut express or iTunes?

Although Macs are typically more expensive then windows the gap between the prices are slowly becoming smaller and smaller.

Now on to the interface.The Mac has a user friendly, not to say cool ^.^ task bar. This allows many of the major programmes on the computer to be easily accessed. However for windows you have to click the start button at the side of the screen instead of just rolling over your mouse over the task bar.

A standard mac mouse however is very truoblesome if you want to right click to see properties of files or to play games. You must first press control then click, this process takes a longer time than a normal right click with standard mouses

Lastly there is a huge difference between the the two computers interface. A standard pc comes with a monitor and a separate processor. The iMac instead integrated this two components into one screen, upgrading the 'cool' factor. However the Mac Pro is an exception to this case, coming in a stylish cpu box.

Thank You for reading this Mac Review!

Pointui, the definitive user interface for mobile devices

Pointui. User Interface for Windows Mobile PDA and smartphones.



As you can see from the video, after loading up the pointui interface(which just takes a few seconds,thats fast) I reach the PointUI home page.
Point UI's Home
The different main functions can be accessed here. Firstly, on the most left of the screen is the call register(phone). Next to it is email(envelope), then sms(speech bubble), and favourite application(star).
At the bottom of the page, is where i can access my contacts, and view running or open up applications.
Browsing through all the different functions of the PointUI is a breeze as it enables touch screen on my HTC touch, together with finger gestures, I can browse through my contacts just by sliding my finger vertically across the screen. It is something common with the iphone. If I want to view my contacts alphabetically, I can move my finger to the right side of the screen and directly slide my finger on the screen again to move to the letter of contact I want.
Applet Ribbon
Sliding with my finger on the home page, I can browse from the clock option to the calendar,tasks, appointments and weather.

Volume Settings
Adjusting the volume settings is rather easy. Touching the screen, you can customize the volume settings according to the different occasions. There are also default settings like vibration mode and slient mode.

My views
From my point of view, I personally like PointUI as I can easily customize the phone settings well for the ease of use. Its design provides an alternative user interface to the normal windows mobile home. And also, its free!
There is a commercial version out there which allows full features of the pointUI.

For more information and download, visit the pointui webpage here.

Ubuntu copies

Yes! I just received my copies of Ubuntu 8.04 Hardy Heron from Canonical today.

You may borrow the cd from me if you want to try Ubuntu. It's a livecd, and also install cd. Which means if you want to give it a try on the operating system first before installing it onto your computer and perhaps destroying your data and formatting your hard drive. Perfect operating system I would say. Will post a review on Ubuntu some time later.

Oh ya. By the way, the cd image is downloadable from www.ubuntu.com

You can also request the cds from canonical directly. They said that the whole process may take up to 10weeks, but I received mine just 2 weeks later after I requested for it. You may want to consider it too as there are cool ubuntu stickers in the envelope, which i paste it on my laptop.

The spirit of Ubuntu

Ubuntu is an african word which means"humanity to others.

Browsing the main folders of my Ubuntu, I found this video, which particularly inspires me about the art of giving and humanity. I hope this video would inspire people to carry on the spirit of Ubuntu.

Respect, help, sharing, community, caring, trust, unselfishness.

These words make up the spirit of ubuntu, which now the linux operating system still insist on it being a freeware for us to share around. I respect Canonical Ltd. and will pass down the message of Ubuntu to everyone.

Its more than just an operating system. Its about the meanings of life.
USE UBUNTU!



Feeling: Inspired
