what is page rank work? is there any value to concern?



Contrary to belief PageRank does not refer to the web page it is named after Larry Page the co-founder of Google Inc.  along with Sergey Brin.  

PageRank is analysis of links pointing to a website the value is derived from the weight of set of documents that contain the link.  It is a complex algorithm which contains many other factors as well. The links on the WWW pointing to a webpage are seen as votes for that page. Hence if a link from page A points to a page B it is passing a vote to it. But the whole webgraph comes into the picture when according a rank.

The PageRank metrics of all pages that link to a webpage are taken into consideration. The pages are ranked from 0 to 10 of which the highest rank 10 is assigned to the most authoritative site. It is believed that page rank does not influence the position on the SERPs since ranking on SERPs depends upon the response to the query. What  that means that how relevant is the webpage for the query. 

The rank is how Google looks at the webpage or website. It is also a value system on the WWW especially for those seeking backlinks and those interested in a link exchange scheme. To the average visitor this ranking system is unknown but for some it creates trust and authority.  The actual ranking system has not been disclosed. 

The PageRank is subject to manipulation this can happen by participating in dubious link schemes and paid text links.  Being a trade secret it is difficult to know how the leading search company determines to penalize as website.

The rank as shown by the Google Toolbar is only a rough guide to what the search company actually has determined. Google updates the rank of the website only few times a year. For greater information read the Google Web Master Central Blog.  One of the blog entry advises web master not to look at this ranking system as sole mertic for the success of a website. 

In short this system is just one of the factors in rankings on SERPs. One need not be much concerned with it. I use this system more as a yardstick in order to create a more authoritative website. What matters on the search side is relevance. 

Cloud base application security

Cloud base application security



There is a growing business in "Cloud-Based" Anti-Virus and security applications.  (e.g. Panda Cloud)  Are they any good?  


Reviewers mostly say that they are.  However, all the reviews I've read so far are based on the same type of useless methodologies as most "big-name" security applications.  (For more explanation on why these testing standards are useless, see my post:  "What's the best Anti-Virus?")

My quick answer:

At this time, I believe that Cloud-Based Anti-Virus and security applications have significant weaknesses and vulnerabilities.  I definitely would NOT use one now, nor in the immediate future.  

Why: 

One of the main "benefits" touted for Cloud AV's is that the virus signature database is not stored on your PC.  Instead, it's stored on The Cloud, where it is "updated more frequently" than it would be on your PC.  Counterpoints:
The frequency of the signature database updates -- in this kind of situation -- will provide little or no "real world" improvement on the security of your PC.  In fact, it benefits the "Cloud Provider" a lot more than it does you.
For a security application to be effective, it must be able to work faster than the virus itself can work.  If the signature database resides in the cloud, even under optimum conditions, accessing the Cloud signature database will be far slower than if it resided on your PC.  Delays in accessing the signature database can have dangerous repercussions.
It is very normal for access to the Internet to be unreliable and unusually slow.
If you have no access to the Internet, your security is severely impaired or non-existent.  ...Even the publishers of these applications admit this.
Another so-called benefit of Cloud-Based Security is that it requires less "System Resources" than applications installed on your PC.  Counterpoint:
For some older Windows XP systems, this might be useful.  However, any system that is well-maintained and "Vista Compatible"-- or currently running Vista or Windows 7 -- has more than enough computing "horse-power" to provide better security using a security application installed completely on your PC.

Is there any Different between Virus & Malware?

Is there any Different between Virus & Malware?



Technically, no. But the difference is mostly Geek Jargon. Here's a brief background to help you understand the differences, and how they affect your choices in security software...

First, there were "Viruses". These programs self-replicated and spread without assistance. They did nasty things ranging from erasing your hard drive, to turning your screen upside down. Then came "Trojans". These programs were secretly installed by non-replicating means, and compromised the security on your computer to allow hackers direct (but hidden) access.

Next came "Spyware" and "Adware". Initially, these programs installed by sneaky-but-legal methods, but quickly devolved into more viral-like, illegal infections. Unlike viruses, these programs are not designed harm your computer. They secretly collect and report information about your browsing and purchasing habits, and/or generate those pop-ups advertisements we all know and hate. However, they DO often slow down your PC, and sometimes damage your system software while installing.

From these basic classifications sprung hundreds of variations and combinations, with two or three jargon terms for each of them. They were grouped into classifications by the burgeoning security software industry, which (of course) made absolutely no attempt to standardize them. A few people (myself included) started promoting the term "malware" as a general term for all MALicious softWARE. But the industry hijacked the term to apply specifically to the Spyware-Adware type of infections.

End result: The differences between "Viruses" and "Malware" are vague an confusing. However, for practical purposes, you can think of the difference primarily as legal. A "Virus" is malicious software that clearly installs itself illegally and/or for illegal purposes. "Malware" is malicious software that installs using sneaky-but-legal methods, and does not perform clearly illegal functions. Another term for this kind of software is PUP ...Potentially Unwanted Programs.

PUPs quickly became such a nuisance that a whole new industry for protection software sprung up around them. Their names usually incorporate the words "spy" or "malware".  Of course, they promoted themselves as an essential element to work alongside Anti-Virus software. However, both Malware and Viruses are detected in basically the same way, and these methods consume a lot of your computer's "horsepower".  Consequently, adding an Anti-Malware program to your computer may significantly reduce it's speed.

Today, most top-line Anti-Virus programs can now detect both Viruses and Malware. Conversely, few Anti-Malware programs also detect Viruses.  Also, the Anti-Malware companies have much less experience with Anti-Virus defense -- which is more difficult than defending against much simpler Malware.

The final difference is that "Anti-Virus" applications only delete the "viral" components of the infection.  They don't "mop-up" the leftover components.  While the leftovers do not pose a large threat for re-infection, most people (including me) are not comfortable leaving them there.

Summary:  Malware-plus-AV products (IMO) do not perform nearly as efficiently as venerable Anti-Virus products that also protect against Malware.  However, anti-malware products can perform better "mop-up" cleaning after an infection occurs, than anti-virus programs do.

On a final note, there are a number of popular, excellent, and free Anti-Malware removal programs. These are often recommended as "security" applications that can be installed alongside any anti-virus Program without impacting performance. This claim is somewhat incorrect. In their free versions these programs do not BLOCK Malware.  ...They will only REMOVE Malware AFTER it is already installed on the computer. Only the paid versions of these programs will BLOCK Malware.  Some of these programs DO include small, passive features that assist in blocking malware, but they do not actively scan files for malicious code the way that an Anti-Virus does.

Tablets, iPads Able to Replace Personal Computers?

Tablets, iPads Able to Replace Personal Computers?




Perhaps you've heard the fireworks and acclaim for iPads, along with the claims that they will quickly replace Personal Computers.  Is this true?


The answer is a little difficult, because all "Tablet" systems -- including the iPad -- are Personal Computers.  They all have the same basic components.  Only the shape is different -- and they run a different type of Operating System.  But Tablets are just as much a PC as your current Laptop or Desktop PC.

Your PC Tech's Short Answer:  No, they will not completely replace Laptop and Desktop computers. However, tablets will be a major part of future computing.  They have significant advantages for light, basic computing needs, but cannot completely replace Laptops and Desktops for "heavy-duty" applications.  (...For the near-future.)

Your PC Tech's Prediction:  Roughly half of all current PC users will buy tablet PCs within the next three years.  Roughly half of those will eventually give up their laptop or desktop PCs, and only use their Tablet PC.  The other half will continue to use both a Tablet PC and a Desktop or Laptop PC.

In addition to this, a large number of people who have never owned a PC at all  (because they were "too complicated") will buy a Tablet PC, and be very happy with it.

Summary:  Tablets may eventually dominate the market.  But for the near future, the physical, technical, and software limitations of Tablets will prevent them from completely replacing Laptop and Desktop PCs.

The first way is to implement a search engine optimization strategy or better known as SEO , the abbreviation of search engine optimation. There are 8 basic points and important elements that you should pay attention to support SEO , namely Domain Name, Title or Head, Meta Keyword, Meta Description, contents / content, Sitemap, Natural listing, and last Backilnk.

SEO techniques are divided into two, namely OnPage and OffPage. OnPage SEO is a technique that is done or applied by arranging from within the website / blog, such as maximizing keywords and descriptions to be more easily recognizable and read by google search engine .

Google Algorithms: Panda Updates

Google Algorithms: Panda Updates


Not to be confused with Panda the animal the update refers to the man behind recent algorithmic changes. The update is named after Navneet Panda the chief architect of recent changes.  This way best SEO practices have been further strengthened. 

As I have been always saying the impetus on SERPs lies on quality site building. This does not mean standard optimization practices have been done away with. The paradigm has changed, it is good quality site first. A website for users and not overtly manipulated for search engines.       

Look deeper into the site especially the design part like download speed, user friendliness, contents etc. Scraper sites or those made for Ads were completely wiped out leaving few that offer good information. Those who relied on content picked up from other sites by intent and habit have suffered the most. The sites have been pushed down deep or eliminated from the SERPs.  The Panda update has pushed the seo professional more towards understanding web design and contents though he may not be a designer. 

Dig deeper in the analytic in order to discover how visitors treat your site. Do they find information they are seeking and easily? This depends upon content creation and link architecture and your analytic will display the time spent on your website. This is called the bounce rate and it tells the search engines how much time has been spent on site - the more the merrier.

Another improvement is the cleanup code duplication, repair some of the protocols on the ICQ, IRC, MSN, and AIM applications. Pidgin 2.8.0 implement a method that allows voice calls more clearly, it is intended that the bandwidth used is not compromised.


This chat application will provide a separate distinction for those who've tried some Instant Messenger applications before, especially in the Window operating system.

Some of the key features that are almost entirely suitable for other applications, so it will give a distinct impression at the time of your chat activity, primarily because of the extra features like "voice" that you can use settings.

In other words, you want to in-app purchase, you unlock and enable the function by entering the PIN code, otherwise it’s impossible to purchase in-app.

Here’s how to disable in-app purchase on iPhone, iPad and iPod touch:

Build Short Url in Twitter


With only 140 characters allowed in Twitter, every single character in tweeting is so precious to express the emotions and feelings adequately. Hence, URL shortening is an important feature in tweeting that allows tweeters to share URLs in their tweets. Users have been relying on third-party shortening services in the past such as Bit.ly and Goo.gl to shorten the URLs into a length that can fit nicely into a tweet. Twitter has finally launched its URL shortening service where URL will be shortened to 19 characters automatically!

In order to minimize the occurrence of malicious URLs in tweets, the links are checked against a list of potential malicious sites in real time when user enters a URL for conversion and warning is flagged accordingly. Furthermore, the original URL is also showed as a shortened version where people who see the tweet will know the site that they are heading to. Alternatively, users can still continue to use their favorite third party shortening service as they wish.

The auto URL shortening feature in Twitter is really simple and instant. Here’s the steps to switch to Twitter built-in URL shorting instead using third-party URL shortener. There is no configuration required to enable or turn on the feature – just start tweeting to enjoy it:


  1. Type/Paste the long URL into the Tweet box
  2. A message appears that inform user that the link will be shortened
  3. Type/Paste the long URL into the Tweet box
  4. A message appears that inform user that the link will be shortened


The shortened version of the original URL is displayed in the tweet once the tweet is posted!


Note that Twitter is currently in the progress of rolling out the feature to everyone and just give it some time if you are not seeing the feature right now. Happy tweeting!

About LED TV


If you've looked at all the fabulous photos of a TV LED catalogs this year and get to buy one for yourself, it really will be useful for your purchase if you know some facts about the first technology. The LED TV had a great reception at CES this year's Trade Show and Samsung was the first that have brought the technology to market with its range 7000 Samsung TV.

In short an LED TV is actually an LCD TV that incorporates additional technology. LEDs are light emitting diodes are an efficient light source while other methods before turning on the LCD screen are used as fluorescent tubes, since the LEDs are used to illuminate the LCD.

While fluorescent tubes providing a light, have some disadvantages. They occupy more space and are heavy in weight. Also not provide enough color quality, and that blacks are not true blacks, which reduces the vibration of all the other colors. This is basically why LED technology came along - which could provide a source of light that can show the pure blacks and whites.

At present there are a couple of LED TVs available to consumers. One is the model with backlit LCD screen allows illuminated with back lighting through a series of LEDs placed behind the panel television. The other is to break through the illuminated edge version, which uses LEDs as a light source placed around the edges of the TV screen. The use of LEDs in the lights back requires a lot of space in the back of the TV, so LED TV thicker in size. The edge-lit LED however, requires less space in the rear and therefore, the designs are much more slender and elegant.

Another useful feature of edge-lit LED TV consumes less energy is not only good for the environment but also save on the monthly electric bill. So the first thing you need to go buy the LED TV is whether I want it back on or edge-lit and the back will be on the expensive to buy. There are also a number of accessory options for LED TVs.

The TV screen can be used as an interface to a personal computer. This makes a TV capable of playing all your favorite songs from your computer, including live feed from any website on the Internet and watching movies online. You can even watch your home videos that are saved on your computer. LED TV sets also come with a USB port that can be used to view the material in your USB flash drive and watch movies, videos or pictures.

Other accessories can be added to the LED TV is Blu-Ray, satellite receivers and digital dish and even game consoles. This is because HDMI ports, which eliminate the need for cables (both A / V and coaxial) and adapters. You can also purchase a wall mount kit with LED if you're interested in mounting the device on a wall in your home. Sets LED TV is much lighter than previous LCD TVs are much easier to hang on the walls. This is especially true for the edge-lit LED TV, which is much lighter and thinner and more able to be mounted.

Installing Cplex in Linux Ubuntu

Installing Cplex in Linux Ubuntu




I've been trying to install ILOG's Cplex product on a 64 bit Ubuntu machine. There are a few small hiccups I encountered.

First, try to install as root with

./cplex_studio122.linux-x86.bin

On my machine I'm installing to /opt/ILOG/CPLEX_Studio122. If you get an error like "jre/bin/java: not found" then you need the "32 bit libs" package:

apt-get install ia32-libs

(You may also need to set the path with LD_LIBRARY_PATH=/usr/lib32). The 32 bit libraries seem to be required only for the installer (at least, they are not needed for programs that just link with the static Cplex libs).

After installing, you may get a build error (running as a non-root user) that it can't find the cplex header files. Try ls /opt/ILOG/CPLEX_Studio122 and see if there are permission denied messages - the installation seems to screw up some permissions on this folder, however this is easily fixed with chmod +r /opt/ILOG/CPLEX_Studio122.

If you are using COIN-OR's Osi class OsiCpxSolverInterface you will also need the following at the top of your OsiCpxSolverInterface.cpp file:

How to Determine the Quality of Software / Web Applications

April 25, 2011 Add Comment
It is not easy to determine the quality of a software or desktop and web applications. Techniques how to determine the quality of software continues to grow in accordance with the development of technology today.


If we look for bugs in the software, we actually will not know exactly how many bugs are contained in it.

Constraints in How to Determine Software Quality


Here are some points that become the reason why determining the quality of software is not easy.
If a programmer tests the program for his own work, the tendency to assume that the program he created is really good could happen. This does not mean that programmers should not test. Testing is limited to unit testing only.

Testing a software takes a long time. So, if the programmer also perform testing then the main task, that is making a program, should be postponed first.

When a programmer tests generally he tends not to record the errors found. If it is done it can happen that bugs that have been found are not fixed.

If we examine further, to get a good software quality, separate program tester is required. However, even if there is a tester, testing can not guarantee the quality of good software.

This depends on several things like good test case design, which can cover almost all possible program errors that occur.

Improper test case design will cause escape test. Escape test can occur because A low fidelity test system, testing the system that includes almost all the features but the very important feature is not tested.

Usually this happens because of poor engineering. The second possibility is the occurrence of a regression test gap, ie the test case does not include where the bug was found. Generally this happens because of limited time or resources.

To manage your software development properly, visit the " How To Manage Application Software Development " tutorial .

Conclusion How to Determine Software Quality


To get a good software quality needs a special division for software testing.

The design of the test case plays a role in determining the quality of the software, when the design of the  test does not cover all the important features, so it can happen low fidelity test or regression test gap. Both of these cause the bug to pass the test.

The purpose of the testing division is to not only look for bugs. The scope of this test includes the performance of the software viewed from the response time when the amount of data and its users a lot, reliability reliability of a software, security, efficiency, and maintainability.

Develop Websites with Bluefish in Ubuntu



Linux is at the forefront of web development, and Ubuntu is a great distribution to use to build and design a website for the first time. Recently, I've been developing web applications using frameworks, and Linux in general makes these things quite a bit easier. Therefore, I figured I should present some of the basic tools you can use to create, develop, and host a website. This may abstract a bit away from the idea of "applications" in and of themselves, but I thought you may all be interested anyway.

The most logical first step for most users is selecting a development environment. Today, I'll highlight Bluefish. Later on, I'll focus on a WYSIWYG editor. (Which, by the way, is kind of difficult to find. Please, if you have any ideas, leave a message in the comments.)

Of course, to put your webpage on the Internet, you'll probably want to use a reliable web hosting. There's about a million out there, and it's hard to figure out the differences between them. I used to have a site on Bluehost, but I eventually cancelled because I thought their support was poor, and I didn't want to fax in a copy of my driver's license just to have SSH access so I could use Rails. I switched to ThinkHost a few months ago, and I've been really happy thus far. They offer reliable Linux hosting with unlimited bandwidth, space, and domains. Better yet, the servers are powered with wind and solar energy, and they plant a tree on your behalf.

Bluefish is a code editor, so users should have a basic understanding of XHTML and CSS, along with any other development languages. I learned HTML rather painstakingly from an outdated code reference, and I don't recommend you do it that way. Instead, try HTML & XHTML: The Definitive Guide published by O'Reilly, which can help even the most talented developer learn new tricks. In fact, it taught me all about the <label> tag, and I felt kind of dumb for previously embedding form labels in only a paragraph tag and wrestling with CSS, but alas...




One of the nicest things about Bluefish is that it uses 30 to 45 percent less memory than other editors. This makes quick edits less of a hassle. Sometimes, other editors can be too clunky, and I found myself reverting to a console-based text editor to make a minor change, but Bluefish should stop this from happening. It has built-in project support, so you can easily open multiple files and keep them organized in the right path. It has all the standard stuff, like line-numbers, search and replace, and code highlighting for languages like HTML, Ruby (go Rails!), Python, and PHP. Best of all, the menu bar allows you to instantly drop in code that developers use often.
Bluefish allows you to connect to a remote server and edit files, so here's a quick guide to using Bluefish with ThinkHost. This tutorial assumes you are using GNOME, though I'm sure you can do the same thing with KDE.
Click on the "Places" menu, and select "Connect to Server...".
In the dialog box, type in your FTP address in the "Server" box. You should be prompted for a username and password.
Now, open up the mounted server in Bluefish, and now you can easily edit and save all of your files on Thinkhost.

How to Hosting a WordPress Blog Website using CPanel

March 15, 2011 Add Comment
How to host a website or blog is very easy if we use CPanel, another story if we use a hosting venue or still not installed anything, we must prepare mysql (for those who use mysql), apache (for those who use php) other.

In the previous tutorial we have discussed how to register the domain, if not please visit the tutorial " How to Register Domain Blog Website Complete " and now it's time we discuss the tutorial how to web hosting or blog with cpnel. Oh yes, in web hosting or blog, whatever it is the kind of blog or its web, the way is still the same. The basic steps are as follows:

  1. Set up local database (can be dumped first)
  2. Prepare php files or similar (asp or other)
  3. Filezilla or other upload tool (ftp)
  4. Where to host (yes yes it is)
  5. Make sure the hosting place is available where our database and php running (usually there is cpnel for this)
  6. Setting the local database settings to the hosting database on the connection php file connection
  7. Testing and running

How to Hosting a WordPress using CPanel

Note the point number 5 above, so that the tutorial is not too widened, in this tutorial we just discuss how to web hosting or blog with cpnel. For those candidates where his hosting does not exist CPanel, will be made a special tutorial to install the mysql and apache database manual. For the type of blog or website we will be hosting in this tutorial is "WordPress".

Still remember the tutorial " How to Install WordPress Offline in Xampp Manual ", there we have installed wordpress locally on our pc, usually this way taken in the framework of development theme. In this tutorial, we will be hosting our local wordpress blog to a hosting provider which of course has provided CPanel.

By following the process in this tutorial, we will move all of our content on localhost (posts, pages, images, etc.), templates, and plugins from the local server to the hosting site.


Step One: Export the WordPress Local Database

The first thing we need to do is export the Local Database database. We will use phpMyAdmin to export. To access phpMyAdmin just type the address http: //localhost/phpmyadmin/in the browser and click the WordPress database. Next, click the Export button on the menu bar.


  • Note that what is exported is the database that we want to host
  • select export menu
  • Export menu
  • Select Custom
  • Select All Tables
  • Compression, select gzip

In the Export Method option select a custom method, which will give us more options to export the database. Select all tables for export and gzip for compression. Scroll down to the bottom of the page and press the Go / Send button to download the database.

Step 2: Uploading a WordPress File (WordPress Hosting)


Now open FTP software and connect to web hosting. Once connected to the site, make sure we upload the files in the proper directory. For example if we want the site to be hosted on yoursite.com, then we will upload all the files in the public_html directory in the hosting server.



  1. Local wordpress web address
  2. Web hosting address
  3. Select all files, right-click and select upload

Step 3: Create a MySQL Database in Server Hosting

When FTP uploads WordPress files, we can all import the database to the hosting server. Because this tutorial discusses how to host a wordpress blog with CPanel, so we will discuss how to create a database using CPanel. Login to the CPanel dashboard and click on the MySQL database icon that can be found in the database section.

After creating the database, scroll down to the MySQL user section and create or add an existing user to the database. After adding the user, CPanel will take us to set the MySQL privilege for that user. Just give all the privileges to the user we just added or created earlier.

Step 4: Importing WordPress Database in Server Hosting

The next step in this process is to import the WordPress database. Please go to the CPanel dashboard, scroll down to the database section and click phpMyAdmin. This will take us to phpMyAdmin.

phpMyAdmin will show you the new database we have created earlier. Click on the Import tab in the top menu. On the import page, click on the file select button and then select the gzip database file (the gzip file we created in the previous step). Finally, press the Go button at the bottom of the page. phpMyAdmin will now import the WordPress database.

Step 5: Change the Web URL

Now we need to change the URL of the web or blog, so we can make the WordPress website can be accessed online. In phpMyAdmin, look for the wp_options table in the database we just imported in step 4. If you change the database prefix, then not wp_options.

Click on the browse button (browse) next to wp_options or links on the sidebar to open a page with a list of fields in the table wp_options. See image below:



Below the field options_name, look for row with value siteurl. Click the Change icon that can be found on the far left at the beginning of the line.

When you click the edit icon, a new window will appear. In the input box ' option_value', we will see local URL like: http://localhost/wordpress. Be careful to enter new site urls in this field, for example: http://www.yousite.com. Save by clicking the Go / send button. Do the same for a field options_name containing home.

Step 6: Setting Database Connection


Now that we have imported the database, and all our content has been uploaded, it is time to configure WordPress. At this time, if we try to access the site, then our site will menu error page in the form of database connection error.

Step 7: Fix Image Url and Broken Link with Update Database


Every time we move a WordPress site from one domain to another, or from a local server to a Hosting site, we will find broken and missing links that also cause problems with image loads. We can use SQL queries or use the WordPress Velvet Blues plugin .
For those who want to do it via SQL, here is a simple SQL query that can solve this problem:


Conclusion How to Hosting Blog or Website

For other settings, we can learn  through the Awesome Examples Fonts page . In the page, we can set the icons to rotate, reversed, given the border and much more. Similarly tutorial install and use the Awesome Font. Similarly tutorial how to install and use awesome fonts , Need to know if in previous version (version 3.2.1), Awesome Font changed the calling code of icons and also on the link from Netdna to MaxCDN , for that before deciding to update the icon, we must learn more about how to retrieve the link and call the icon (fear that there is another change).




Windows 8 to Integrate Xbox Live Gaming and Entertainment Service

Windows 8 to Integrate Xbox Live Gaming and Entertainment Service



Xbox Live online multi-player gaming and digital entertainment service first introduced on Xbox 360 game console are one of the few markets that Microsoft really succeeds in. Thus it’s kind of expected that Microsoft wants to bring the online gaming and entertainment experience to all kind of devices and platforms. The long term initiative is called Live Anywhere where among targeted platform is Zune, Windows OS, and Windows Mobile phone, in addition to Xbox.

Microsoft already integrates Xbox Live into Windows Phone 7 as one of native feature, and will also integrate Xbox Live natively into Windows 8, as one of new features of Windows 8. In fact, Windows XP, Windows Vista and Windows 7 already has an online gaming platform based on Xbox Live called Games for Windows – Live, where all users also get to download Tinker PC game for free. But Games for Windows – Live is not come pre-installed on Windows, nor tightly integrate with Windows, and it’s mainly tilted towards gaming. In Windows 8, Xbox Live will be tightly integrated, and expands beyond gaming with digital content delivery to make Xbox Live the core entertainment service.

According to Mike Delman, vice president of global marketing at Microsoft’s Interactive Entertainment Business group, when he was interviewed by Seattle Times, “Xbox Live will be built into the PC. It will be the service where you get your entertainment. We were talking about it — you will not just see consoles and handhelds at this show next year, this show’s going to morph into other devices.” With the availability of Live TV and VOD (video-on-demand) from major cable networks and service providers, Xbox Live is gearing up to fight off increasing competitive market in providing entertainment services, chief among all, the iOS ecosystem of iPhone, iPad, iPod touch and Mac OS X with iCloud and cloud-based iTunes offerings.

Mike Delman also gave some clue on how Xbox Live services and content be part of Windows 8:

There will be a lot of similarities in design and service philosophy. Whether it’s us or Apple or anybody else, people want to be able to navigate through multiple devices in a certain ecosystem very seamlessly so we’re committed to that.

And the Xbox Live will also go the way of “buy one play it anywhere”. Xbox Live has already built based on cloud service concept, and with Xbox Live been integrated more and more platforms and devices, Microsoft promises Xbox Live will be the pervasive cloud media service across devices, that works with Windows PC as well as Windows Phone and Xbox.

It’s our job to make “buy a movie in one place and play it everywhere, buy a game in one place and play it everywhere.” Making things portable will be a big focus of ours.

Microsoft has already prepared Xbox Live to elegantly blending into the new Windows 8 and Windows Phone 7 tile-based user interface. During E3 keynote address, Microsoft revealed that Xbox Live will have a new Dashboard design, which is also based on the “live tile” on immersive Metro UI.
