I am Gururaj, India. I just started this blog as a hobby and to share what I know, but later due to an increase in the visitors response I took blogging a bit more seriously.

I have a passion towards the computer technology and have so much addicted to my PC that can’t live without it. Most of the time I live on my PC. Some times even more than 15 Hours/Day.

Game Programming is my passion. I always want to explore and come up with the new ideas. So here on this blog I’ll share my ideas with you. This blog is wide open to suggestions and feedback.

Facebook beats Orkut in India

An amazing history for Facebook subscribers in india which hit famous socialnetworking site Orkut in India.Although Orkut witnessed significant growth in countries such as Brazil and India,recent statistics by major research firm comScore shows that Facebook has taken the throne from Orkut in  india.Facebook usage rose by 179 percent as compared to last year while Orkut did a meager 16per cent.

SONY PSP 2 ?
If you are a gaming freak and having intrestead in high end graphics and good portable media along with you,here the latest prototype of brand new sony psp 2 which will be launched this october with android3.0-based and features analog controls in the form of a"long touch pad",regular PSP buttons,a 5MP camera,1GHZ snapdragon processor,as well as a large display that is anywhere between 3.7 and 4.1 inches.As for looks,the prototype is "mostly black with some silver highlights,and the gamepad area is white/silver in color."

This 'PSP2' will reportedly have access to a special games section at the Android Market,and will supposedly release by October this year.

Billiondollar companies have a penchant for acquiring technology the easy way,and Google's   take over of ITA software,   a leading flight information company,for $700 million,is  a classic example.
The industry is certainly buzzing with questions.What exactly does Google intend to do with a $700 million flight information company?

Google has not said how they intend to use  ITA,except by commenting that they'd honour all of ITA'S previous  commitments;most notably service agreements with microsoft's Bing,a part from the more obivious Kayak and Orbitz.

Google is looking to expand the offering of the Android OS,and has forceful taken aim at emerging markets,such as india and china,with cheaper handsets catering to the untapped masses.

Andy Rubin,vice president for Engineering at Google,recently commented about the potential of these markets:'the down-market opportunity is about to happen.It's actually quite a revolution".

A part from low cost handsets.Google intends to provides payment gateways for applications developers,allowing them easily accept payments and still things like subscriptions.

Low-cost handsets makers have already noises about their upcoming Android devices,such as Huawei,LG,and Samsung. 

Lemon Mobiles,a relatively recent entrant into the Indian mobiles market,has also announced a low-cost Android 1.6 mobile,called the pi ,which stands for Professional One.In related news,Reliance will also be launching first Android CDMA phones in india -the samsung Galaxy i899.

Battle For  Social Networking For Highest Authority/Power:Google vs.facebook

Just when people had started using Face-book and Google as  the two internet giants,it appears that Google will attempt to pull the ground from under Facebook's feet,by launching a new social networking services of its own called "Google Me" and simuntaneously rope in the famed services of Zynga,the social gaming developer of facebook fame.This news comes after TechCrunch's reports that Google has pumped in between $100m to $200m into Zynga.

Zynga has been doing rounds on Facebook,growing in stature and popularity with such hot games like Farm ville and Mafia Wars.Everybody is amazed by the company's potential,with the current estimates pegging Zynga's 2011 revenue at $1 billion.Google's internet in Zynga seems obvious,for Google Games with Zynga's experties will give them a hold on the social gaming sphere,and open up another battel front with the social net-working behemoth-Face-book.

Mean while,conjecture has it  that the new Google Me services will be an enchanced,and more integrated version of the current Google Pro-files.To support this,there's also news that Google Buzz's  lead Developer ,Rick Klau,is now working on Google Profiles.

A move like this,really emphasizes how much Google wants to domainate the social networking space,and they certainly do have potential, if Gmail, Docs ,Maps,calender,Orkut and even search are properly integrated .Although,out playing Facebook in the own backyard would be easier said than done .Not to forget the bungled launch of Google Buzz!

Best Social Media Tips

Plunging into social media for the first time can be a bit daunting for individuals or businesses. There is a learning curve when it comes to becoming more social online, and it can take a while to learn what works and what doesn’t. Here are a few of the best Do’s and Don’ts that can save you time and help grow your social media authority more quickly.

1. Start small

You’ll want to start small and try a couple services out at a time. Oftentimes newbies sign up for every social network under the sun and try to grow each of them. Guess how long they last? Building profiles for multiple social sites is hard work, so it’s best to start by only tackling a couple at first.

Once you find the right ones for you or your brand, then start to narrow your focus on those. Eventually you may want to scale your social media strategy to include more services, but you have to crawl before you can walk.

Start small, and then grow to other social networks as your confidence grows. Success breeds success.

2. Get a widget

Put a widget up on your site for your social networks. The best place to find followers is your own blog or site. Also, it’s much easier to get your readers and friends to vote or retweet your content than strangers. Adding a widget next to your content can help.

Facebook has a widget generator you can use, and the Tweetmeme badge is easy to add to your site as well.

3. Frequently test your buttons and widgets  

Start testing which social media profiles have the most impact, then drop the rest. For example, if your site does really well with Facebook shares but hardly ever gets voted on Digg, then drop the Digg vote button.

Oftentimes you’ll see sites littered with tons of widgets and buttons. Having a gazillion widgets at the end of each article only creates noise and annoys the reader. Figure out which buttons are getting clicked, and drop the buttons that don’t convert. Ideally you’ll only have two or three widgets on each page.

You can tell which buttons are effective by using Google Analytics and goals to see who’s clicking what. You can also use A/B to see which types of buttons are getting more clicks.

4. Don’t annoy your followers
Sounds like common sense, right? Unfortunately, lots of companies that are just starting out with social media think the best way to “promote” their brand is to publish coupons, offers, news, and anything else related to their business.

Rule of thumb: if it’s something you personally wouldn’t like to receive, avoid it.

Your social media goal is to be helpful first. People follow and respect brands that are helpful, not self-promoting shills. Give first, then ask.

Try posting useful links to industry articles, answer questions, and engage. The followers, engagement, and ultimately sales will come if you’re helpful first.

5. Don’t fret about follower counts

Don’t believe all the spammy ebooks out there that sell you the notion that you can attract thousands of followers in a matter of days. Sure, you could do that and it’s not hard. But the types of followers who are going to be following you are mostly bots. Or they’re just following you in hopes that you’ll follow them back. Ultimately, they aren’t followers who would engage with you.

You want social media followers that are going to listen and interact with you, and 10 of those followers is worth more than a thousand bots.

It takes a while to organically build up a great social profile. Focus on building great content and being helpful, and the followers will come.

6. See what the pros are doing

Everyone has a different strategy when it comes to social media, and sometimes it’s best to take a look at people who are real social media experts. Lee Odden is a good example of someone using Twitter and Facebook to help people, which in turn grows his social media influence.

There are plenty of fantastic examples of people who truly understand how to interact and build powerful social media profiles the right way. Check out sites like WeFollow to find influential Twitter users within your niche.

7. Don’t overlook niche social media site

When people think of social media, they typically think of Twitter or Facebook. But there are literally hundreds (maybe thousands?) of social media networks and sites that you can use to help promote your brand. Jut because a network isn’t huge doesn’t mean it’s not going to impact your social media strategy. Oftentimes targeted niche social sites can bring more targeted traffic to your site than larger sites.

If you’re smart, you can use smaller social networks to help promote your site on other bigger social networks. For example, I’ve written posts on web development that have made it to the front page of Dzone, a social media site for web development. Once the article made it to the front page of Dzone, the attention brought a lot of saves on Delicious, and subsequently made it to the Delicious front page. The delicious front page brought even more traffic, and those Delicious users voted the story up to the Digg front page. So, by simply submitting my site on a smaller niche news site with a great headline, I managed to make it to the coveted homepages of both Digg and Delicious.

Niche social news sites can be very powerful, and oftentimes much easier to become influential in than the larger sites. Here’s a list of social news sites organized by category.

8. Find people within your niche to follow on Twitter

The ideal follower on Twitter is one that has similar interests within your niche. You can find like-minded people to follow on Twitter through these directories and odds are many will follow you back.

Once you’ve started following these people, start interacting with them. Participate in discussions, and retweet things they say that would be helpful to your community.

Not only will this method help build your follower counts, it also gives you more influence within your niche. You’ll find great friends that will help you promote your content and site too. Always remember to give first and ask later.

9.Stay Humble

Social media beginners often try to quickly establish themselves as “experts” within their field, but they have nothing to back it up. (For example, search for “social media experts” on Twitter. You’ll find many with only a handful of followers. Shouldn’t an “expert” have more?)

As with anything in life, nobody likes a know-it-all. Be humble. Ask questions. Teach, but don’t preach. Let others do the hyping for you. And they will if you’re helpful and humble.

In September and November 2010 scientists and astronauts at NASA will be  bidding firewall two of their space shuttle flights  the 133rd and the 134th.The mission duration of these flights will last for 11 and 10 days respectively ,both the flights will carry major components  for the ongoing build of the International Space Station(ISS).The STS 133 will be carrying  the Discovery space shuttle  while  the STS 134 has the responsibility to load the Endeavor in to the Low Earth Orbit Where the International Space  Station is being assembled piece by piece.A major aerospace engineering  endeavor the ISS project was launched in November 1988 and as of Summer 2010,25 Space Shuttle flights  have docked with ISS to add elements.

Run Multitasking in i Phone 3GS i OS 4

Finally Multi tasking allows you run multiple applications at the same time. This means for example you can continue listening to music on iPod while browsing the web or sending an email. Or, you can now receive VoIP calls and have conversations while using another app.

For the most multitasking seems to work transparently and very quickly without you even noticing it. For example you are now able to upload photos to Flickr but without having to keep the Flickr app open. In this case, the Flickr application will keep uploading those photos while you go read your email or check the weather.

iphone iOS4 multitasking

Play music on the back-ground and access the music controls in the multitasking bar This feature I really like. When playing music on i Pad and using other apps, double tap the home button and swipe to the left to see the i Pod controls. See below.

i Phone i OS 4 multitasking bar i pod

What can’t  apps do while in the background?

Grab new updates: those of you who were hoping that your Twitter, IM, or IRC client would pull down updates while hanging out in the background will be disappointed. Unless those apps make use of push notifications to alert you of new messages (as the AIM app does), apps won’t be able to check for updates on their own unless they’re in the foreground.

Multitasking and performance
There has been some cancers that multitasking might slow down the iPhone. As you will be see from the video on top of this post, I had about 12 apps open including video and audio, and didn’t notice any speed issues.

iOS 4 Compatibility

iOS 4 will work with iPhone 3G and iPhone 3GS. Support for the second and third-generation iPod touch will be available this summer, iPad support will be available in the fall.

How do I close any of the open applications?
To see all your open applications double-tap on the home button to pull up a pane that shows which apps are open in either a live or suspended state. To close any of the apps hold your finger on any of the ions to see the minus signs. See the picture below.

Plaintext_len_min Plaintext_len_max

table_index chain_len chain_num part_index

The table_index is used to define which reduce function to use for the table and the part_index is for deciding how to generate the initial starting point for the rainbow table.

The settings recommended by the creators for the software for a 99.9% probability of cracking hashes are (for md5): rtgen md5 loweralpha-numeric 1 7 0 3800 33554432 0 Instead of md5,you could have used any other algorithm here.Rainbowcrack can be extended using dlls to support hash algorithm.Here we are generating a rainbow table with the following specefications.


hash_algorithm	md5
charset	loweralpha-numeric=[abcdefghijklmnopqrstuvwxyz0123456789]
plaintext_len_min	1
plaintext_len_max	7
chain_len	3800
chain_num	33554432

This command has to run 6times for each table index,from 0 to 5,and each time it will take around 2hrs on a Core i5 system!Each resulting file will be around 512MB,making the whole table collection around 3GB in size.

As you increase the number of characters in the character set and the length,the size will go up drastically.

This will result is file named "md5_loweralpha-numeric#1-7_0_03800x33554432_o.rt" to "md5_loweralpha-numeric#1-7_0_3800x33554432_5.rt" The resulting rainbow table will not be stored,and hence will not be easy to search in.So the next step is to sort the table using the rsort command.This command simply takes the filename of the unsorted tables as a paramater.

This takes under a minute to execute. Since rainbow table are large,you can also use rt2rtc command to compress the table into".rtc" files which can be used with the cracking applicaions without needing to be decompressed. Now that we have out rainbow tables,what do we do next?Use them of course! The following images show how easy it is to do with the graphical Rinbowcrack GUI.

The Windows registry

For all the people using Windows,it is very helpful to learn about one of the most important aspects of any windows system,the windows Registry.The registry in windows is a central database of all configuration settings for most of the application installed on your computer.It is used extensively by Windows for storing all its setting and by most Windows  application.The Windows registry allow one to configure many settings for windows and other application which are otherwise not accessibly by any  interface that the application provides.

By Understanding a few things about the windows registry you can go for long way towards hacking your system into what you want it to be.Editing the windows registry is one of the most Powerful ways of manipulating yous ystem settings,which is something that makes it equally dangerous.

So before you set out to do anything with the registry,please back up your system registry.If you are using the system Restore/System protection feature in windows create a recovery Point.

Even so,there are many tools out there which  will help you accomplis some advanced registry manipulations without needing to edit it manually.

To edit the Windows registry,the simplest tool to use--One which is free and works reasonably well-is the registry editor which comes bundled with Windows:regedit.It can be launched using the RUN dialog(Windows Button +R)by entering the command regedit and hitting[enter]

The Windows regedit in any  recent Os will display the following 5 root key entries:

HKEY_CLASSES_ROOT

HKEY_CURRENT_USER

HKEY_LOCAL_MACHINE

HKEY_USERS

HKEY_CURRENT_CONFIG

All this settings are not stored in a single file,but are instead spread across multiple files in logical

groups called "hives".The combination of data  from these "hives"makes up the windows registry.

HKEY_LOCAL_MACHINE

Abbreviated as HKML.According to its description in Microsoft  TechNet:TheHKEY_LOCAL_MACHINE sub tree contains information about the local computer system,including hardware and operating system data,such as bus type,system memory, device drivers,and start up control parameters.The software sub key in this key contains the bulk of the system-Wide settings for application installed in windows.The setting in this  section are usually arranged as company/Product/version as those are Microsoft's guidelines.setting for Microsoft's own applications will thus be found in HKLM/software/Microsoft own applications will thus be found in HKLM/software/Microsoft,with settings for windows itself under Windows.

HKEY_USERS

This key contains user configuration Keys for each user.It has one subkey for each user is named after the user's security ID.For explanation of what is combined in the subkeys read on for HKEY_CURRENT_USER.

HKEY_CURRENT_USER

Abbreviated as HKCU.According to its description in Microsoft  Tech Net:The HKEY_CURRENT_USER Sub tree contains the user profile for the user who is currently logged on to the computer.The user profile includes environment variables,personal program groups,desktop  settings, network connections, Printers,and application preferences.The data in the user profile is similar to the data  stored in the Win.ini file in Windows3.x.

The HKEY_CURRENT USER Sub tree does not contain any data .It just stores a pointer to the content of the HKEY_USER\security ID(SID)of current user sub key .Therefore,the content of that  sub key also appear in HKEY_CURRENT_USER,and it can be viewed and changed in either location.This sub tree provides easier access to the data.

HKEY_CLASSES_ROOT

Abbreviated as HKCR,this part of the registry is for storing file associations and information about application registered for handling different data types.These settings can be overridden by the current user's settings for the same stored in HKEY_CURRENT_USER/Software/Classes.

HKEY_CURRENT_CONFIG

It merely links to HKEY_LOCAL_MACHINE\System\Currentcontrolset\Hardware Profiles\Current and contains information generated at run time.©®
