Should you wait to buy a tablet?

The hype around tablets is deafening this year–but is it really the right time to buy one? It’s a good question (and a loaded one), so let’s get to the bottom of it.

What features are you waiting for?
Currently, the Apple iPad holds the majority stake in the tablet market, with a growing share coming from Android-based tablets like the Samsung Galaxy Tab. The features you can expect from this current crop of tablets include the core capabilities of e-mail, Web browsing, and multimedia playback, along with Wi-Fi, cellular, and Bluetooth wireless communication. Other features–such as gaming, over-the-air media downloads, printing, keyboard support, supported App stores, e-book reading, cameras, video chat, GPS navigation, and multitasking–are also available on today’s crop of tablets.

From where I’m sitting, there’s not much more we can ask of tablets. Sure, I wish the iPad had cameras and FaceTime video chat support, but it’s certainly not crippled without it. There are the features that could always be better, such as processor speed, screen resolution, and battery life, but those are moving targets you can never pin down. 

We’ve seen some manufacturers break new ground with dual-screen designs (Entourage Edge, Toshiba Libretto W100), or impressively large screens (JooJoo), or small screens (Archos 28), but nothing that’s shaken our belief that 7 to 10 inches is the Goldilocks zone for tablets. Too big, and things get unwieldy. Too small, and you may as well be using a smartphone.

If there’s one killer feature I believe consumers are really aching for, it’s competition. Currently, the iPad is running the show and not much else is even competing in the 10-inch arena. If you wait, you’re almost guaranteed more competitors, but it’s doubtful they’ll offer many more features than the iPad, simply because there aren’t many compelling features left on the table.

Android 3.0 (Honeycomb) may bring to the OS some needed optimizations for large-screen tablets.


What products are on the horizon?
We have a pretty good idea of what to expect from tablets in 2011. There will almost certainly be another iPad, and it will likely land in April again, because Apple tends to recycle release time frames. If I had to predict it, the next iPad will be thinner, more powerful, and include front and rear cameras with FaceTime support. If those are the killer features you’ve been waiting for, April of 2011 is just around the corner–so by all means, wait. Then again, with Apple’s resale values what they are, you could probably buy an iPad now, and sell it at a modest depreciation in March without much hassle.

To keep things interesting, 2011 will likely see Google releasing a tablet-optimized version of Android (rumored for Honeycomb ), chock full of tablet-optimized apps. If Google can pull it off and keep the OS and its apps from fragmenting in a new direction, it’ll have (or, arguably, maintain) the strongest contending tablet OS to take on the iPad’s iOS.

The bad news is that there’s nothing to suggest that the other issues we’ve had with Android-based tablets will disappear. Drawing on our experience with the Galaxy Tab and the Dell Streak, the best Android tablets have so far come hand-in-hand with two-year carrier contracts or bloated off-contract prices. The Android-based tablets that have dodged carrier lock-ins (Nook Color, Archos 7) have done so without the official Google App Market, which is a critical component of Android’s appeal.

Fortunately, there are many successful companies betting on Android to work as a strong, viable tablet OS. With the reputation of so many at stake, we’re bound to see more Android-based tablets spring forward as strong contenders to the iPad. But getting back to the original question, will that day be worth waiting for?

Even if an Android 3.0 tablet arrives with must-have features, at what point is a product too late? We’ve seen how Apple swooped in and dominated the MP3 player space with the iPod, and maintained that momentum even in the face of strong competition from Microsoft, Samsung, Creative, and countless others. The tablet space could be a repeat performance from Apple, if manufacturers don’t act quickly.

Beyond Android, we know we’ll be looking at the BlackBerry PlayBook in the first quarter of 2011. It looks like a powerful competitor to the iPad. Like the Samsung Galaxy Tab, though, its 7-inch screen size puts its total dimensions at half the size of the iPad–which can be seen as a blessing or a curse. BlackBerry also doesn’t have the app inventory of Apple or Google, which may be a deal breaker for many right out of the gate.

We also expect that HP will finally reveal a tablet running the WebOS platform it acquired from Palm. HP has a history for great hardware, and its HP Slate 500  demonstrates that the company has what it takes to pull the trigger on a feature-packed 9-inch tablet. That said, HP will need to pull off some serious PR maneuvers to raise WebOS from its grave and pitch it to consumers (and app developers) as a hot new product–not an exhumed corpse.

There are also outlier products: Linux tablets, Chromium tablets, Window 7/CE tablets. I haven’t seen anything promised from these camps to make me optimistic, but CES 2011 could have me changing my tune.

Will things get cheaper?
Technology always gets cheaper, and tablets are no exception. To me, the iPad’s most tantalizing competitor right now isn’t the comparably priced Galaxy Tab, but the Barnes & Noble Nook Color, priced at $250.

Given that most of today’s tablets already have the features we’re looking for, one of the only areas of innovation left is price. The Nook Color is a great example. It has a tenth of the features of the $500 iPad, but at $250, it’s burdened with far fewer expectations. With it, you can browse the Web, check your e-mail, read a book, and listen to music. You don’t get all the technology–the apps, GPS, Bluetooth, 3G, cameras, video chat, games–but for many, that’s just fine.

Whether you’re buying a car, a computer, or a box of cereal, the anxiety that comes along with making the right buying decision is always proportional to the amount of money at stake. Will there be a $199 tablet in 2011 that’s actually worth your time? I think there’s a good chance of it, but like the Nook Color, it won’t be riding the cutting edge.

If you really want a tablet, there aren’t many compelling arguments for waiting. From a technology perspective, there are no game-changers on the horizon, as far as we can tell. That said, we expect that low-priced tablets will flourish in the coming years, so steer clear of two-year carrier contracts if you want to stay nimble.


Jury: SAP must pay nemesis Oracle $1.3 billion

SAN FRANCISCO – Oracle Corp.’s courtroom clash with archenemy SAP AG has paid off handsomely.

Larry Ellison

A jury on Tuesday ordered SAP to pay $1.3 billion — more than half of its total profit last year — for a subsidiary’s skullduggery in stealing a stockpile of software and customer-support documents from password-protected Oracle websites.

The German software company was caught off guard by the size of the verdict. It had only set aside $160 million for anticipated damages, and already paid $120 million of that to Oracle’s lawyers.

The penalty is one of the largest on record for software piracy, and has the potential to reshape the business software landscape because of the extent of the damage to the pocketbook and reputation of one of its biggest players.

The verdict came after less than a full day of jury deliberations, and followed a three-week trial that turned into a Silicon Valley sideshow.

Stoking the drama were colorful public provocations by Oracle’s outspoken CEO Larry Ellison, the looming possibility of a crushing verdict against a company that makes ubiquitous business software, and the specter of Silicon Valley’s most elusive new celebrity, Hewlett-Packard Co. CEO Leo Apotheker.

In the end, Oracle turned the trial into a double feature: a grinding attack on SAP, whose dominance in business applications is under assault from Oracle, and HP, another technology industry heavyweight with which Oracle shares a decades-long partnership that is now coursing with bad blood.

“For more than three years, SAP stole thousands of copies of Oracle software and then resold that software and related services to Oracle’s own customers,” Oracle co-president Safra Catz said after the verdict. “Right before the trial began, SAP admitted its guilt and liability. Then the trial made it clear that SAP’s most senior executives were aware of the illegal activity from the very beginning.”

Representatives of SAP, which is based in Walldorf, Germany, expressed disappointment and said the company will “pursue all available options, including post-trial motions and appeal if necessary.”

If the size of the punishment is ultimately allowed to stand, SAP’s takeover in 2005 of a small software-support firm called TomorrowNow, which dragged the company into this mess, will end up costing SAP significantly more than the $10 million it paid for the acquisition.

“This will unfortunately be a prolonged process and we continue to hope that the matter can be resolved appropriately without more years of litigation,” SAP said in a statement. “The mark of a leading company is the way it handles its mistakes. As stated in court, we regret the actions of TomorrowNow, we have accepted liability, and have been willing to fairly compensate Oracle. … Our focus now is looking forward.”

SAP faces another potential problem as well. It previously disclosed that the U.S. Department of Justice is investigating the matter.

It’s difficult to think of a more thorough legal victory for a software maker pursuing a copyright infringement claim, said Santa Clara University law professor Eric Goldman.

Besides collecting the damages, Oracle was able to publicly humiliate one of its biggest rivals while making another competitor, HP, squirm as it skirted questions concerning the whereabouts of its new CEO, Leo Apotheker. Oracle repeatedly tried to serve a subpoena on Apotheker, a former CEO and top sales executive at SAP, but couldn’t find him within the jurisdiction of the Oakland federal court.

“Oracle has always dreamed big in this case and all their dreams came true,” Goldman said. “It just turned out to be a real windfall for them.”

SAP boxed itself into a corner by admitting it had trampled on Oracle’s copyrights before the trial began. That left SAP with little to do but plead for leniency and “it turned out to be a tough sales pitch,” Goldman said. “This was just a bad case for SAP, up and down the board.”

Oracle, based in Redwood Shores, is the leading maker of database software, which helps companies organize their information. Its aggressive expansion into business applications has forced Oracle into a faceoff with SAP, the leader in that space.

HP was a late addition to the dustup: After HP’s former CEO, Mark Hurd, was ousted in August in the wake of a sexual harassment investigation, Oracle hired Hurd, HP hired Apotheker, and Ellison used both of HP’s decisions as reasons to blast the company.

At the heart of Oracle’s claim against SAP was a series of golden gotcha moments, in which Oracle noticed unusual behavior on secured websites it maintained to help customers solve problems, and uncovered a scheme in which an extraordinary amount of software and documents were being plundered and shipped back to TomorrowNow servers.

Oracle technicians spotted the scam by investigating accounts that were registered with clearly bad information (such as phone numbers like “777-7777”) and user names seemingly connected to the SAP subsidiary (names such as “Tom Now”).

SAP admitted that the now-shuttered subsidiary was secretly siphoning off instruction manuals and technical specifications for Oracle’s software. But its lawyers argued that Oracle’s claims of injury were exaggerated.

Oracle demanded billions based on its estimate of the value of its intellectual property and business it lost.

SAP posited that TomorrowNow actually wasn’t that good at stealing customers from Oracle, and that SAP should only pay for money it made from the 358 customers it gained with the stolen data.

The jury sided with Oracle’s argument that the value of its intellectual property is vast, and that aggressively enforcing copyrights is critical to nourishing a healthy technology industry and funding innovation.

SAP conceivably could ask the judge to lower the damages determined by the jury, but that is usually a difficult argument to win, Goldman said.

“The size of this verdict further reduces SAP’s flexibility,” he said.

SAP shares fell 67 cents, or 1.4 percent, to $48.02 in extended U.S. trading, after the verdict was announced. The stock had fallen 71 cents, or 1.4 percent, to finish the regular trading session at $48.69.

Oracle shares rose 37 cents, or 1.4 percent, to $27.56 in extended trading, after falling 86 cents, or 3.1 percent, to finish the regular session at $27.19.

Facebookers’ Feeds Crawling With Malware, Security Firm Finds

Facebook has attempted to ramp up its security as the social network has grown, but malicious links and scams still seem to slip through. Of the 14,000 Facebook users who installed the BitDefender Safego app, 20 percent have malware somewhere on their walls or news feeds. However, “We stipulated that we were talking about 20 percent of the Safego users, not [20 percent] of all Facebook users,” a BitDefender spokesperson said.

Links to malware-infested sites and other threats lurk in many Facebook users’ news feeds, according to research from security vendor BitDefender

Among approximately 14,000 Facebook users who installed BitDefender’s Safego security and privacy app, about one in five has malware in his or her news feed.

More than 60 percent of the attacks detected by Safego are malicious apps that promise various benefits but install malware when they’re downloaded, BitDefender spokesperson Dan Wire told TechNewsWorld.

Sixteen percent of attacks use worms that spread using specially crafted messages that are likely to attract attention.

However, Wire warned against using those statistics to reflect on Facebook as a whole. “We stipulated that we were talking about 20 percent of the Safego users, not [20 percent] of all Facebook users,” he pointed out.

“The tools and systems we’ve built, combined with concerted campaigns to arm users with the information to make smarter and safer decisions online, have limited the number of Facebook users impacted by security issues to less than 1 percent, and that’s since the founding of the site more than six years ago,” Facebook spokesperson Fred Wolens told TechNewsWorld.

Breaking Down the Safego Stats

To date, about 14,000 people have installed the beta version of Safego, a privacy and security app for Facebook that BitDefender launched about a month ago.

Safego has scanned more than 20 million objects on those users’ pages since then, and it’s found that 20 percent of the users have malware in their news feeds. That means “everything that the user sees — his wall and what his friends post to their walls,” BitDefender’s Wire explained

Just over 21 percent of the malware lets users perform actions normally prohibited by Facebook. Just over 15 percent sucks in victims by offering bonuses for various games hosted by Facebook. For example, they offer free coins on “Farmville” and “Mafia Wars.” More than 11 percent provide features Facebook doesn’t offer. For example, they let you change your background or include a “dislike” button.

Various other forms of attack were also used, but less frequently.

What Safego Does

Safego checks users’ privacy levels and identifies personal information that’s visible to strangers. It also scans the user’s wall, inbox and comments for malicious links and compromised shared content such as videos and photos.

The app also protects users’ friends — users can warn their friends about infected links in those friends’ Facebook accounts.

However, Safego doesn’t block anything; it only warns users of malware.

Going Beyond Facebook

Despite having its own IT security team, Facebook has repeatedly been hit by malware and spam. Only last week, it was hit by a new attack in which a fake email told users their Facebook password had been changed and asked them to install an attached app. When they did so, a Trojan was downloaded instead.

Further, WebSense statistics showed that between June 22 and July 12, 40 percent of all Facebook status updates contain links and 10 percent of those links were either malware or spam.

“We analyzed half a million posts that were collected by Defensio,” Websense spokesperson Patricia Hogan told TechNewsWorld. Defensio is a Facebook security app from Websense.

However, Facebook contends it’s ahead of the game. “The systems we’ve built have helped us stay one step ahead of our attackers so that, as we’ve more than doubled in size over the last year, the actual effect of the attacks on Facebook hasn’t changed,” company spokesperson Wolens said.

Then can Safego spot malware when Facebook’s own security can’t?

“We use our cloud scanning technology in which there’s a synergy of all our products — our antispam, antiphishing and antimalware technology,” BitDefender spokesperson Wire explained. “We also look at applications that don’t necessarily have a malicious payload like stealing money but spread like a worm instead.”

Facebook has begun urging users to make its website their homepage, and that could increase the threat to PC users.

“If you make Facebook your homepage after you’ve been a user for some time, probably nothing dramatic will happen; Facebook will probably just get more users,” BitDefender’s Wire said. “But if Facebook’s site comes as the browser default on a new computer and the user is not aware of security and privacy issues, that would make the problem worse.

New Newspaper Could Be Published Only on the iPad

New Newspaper Could Be Published Only on the iPad

Rupert Murdoch’s News Corp. could produce the first newspaper that would be for the iPad only, with no print or web edition. Murdoch’s The Daily would reportedly cost 99 cents a week or $4.25 monthly, with news gathered by a staff of 100. While Murdoch wants to end free news, The Daily on the iPad could face the sorry fate of other attempts.

As far back as last year, when Apple’s iPad was nothing but an unconfirmed rumor, there have been reports that the computer giant was talking with media conglomerates about developing content exclusively for the device. But so far, the top-selling tablet computer has only featured applications that optimize media presentations on its 10-inch screen.

Now there are reports that the first iPad-specific newspaper, The Daily, may be produced by Rupert Murdoch’s News Corp. for the iPad’s seven million (and counting) users. The start-up would have no print edition or web site, nor links to or from web sites.

Product of Sleepless Night

The Daily would reportedly have an initial staff of 100 with three veteran managing editors. It would be available on the iPad for 99 cents a week or $4.25 monthly, according to Women’s Wear Daily.

The publication said Murdoch had a vision of the iPad newspaper during a sleepless night in May and proceeded to invest $30 million and staff the new venture. At that time, the newly launched iPad was clearly a hit, but the extent of its popularity had yet to unfold. Apple now says more than seven million iPads were sold through September.

WWD said Jesse Angelo, a former New York Post official and top Murdoch confidant, is closely involved in the project and in line to be editor. Also reportedly hired as managing editors are Mike Nizza, formerly of AOL, The Atlantic, and The New York Times; Pete Picton, the former online editor of The Sun; and former ABC News producer Steve Alperin. Also on board are Richard Johnson, the Post’s top celebrity-news reporter and New Yorker magazine music critic Sasha Frere-Jones, according to WWD. The Daily would be mostly original content with some video  from Fox Sports.

Looking for Net Gains

News Corp. has struggled to find ways to reverse the trend of free news content on the Internet and recently started charging users for access to articles on The Times of London and The Sunday Times. Most newspapers have found that approach futile.

When New York Newsday, which is owned by Cablevision, began that approach, it only gained 35 customers who weren’t subscribers to the paper or Cablevision, according to reports. The New York Times said News Corp. only received about 100,000 payments for stories in the first four months of paid content, including those from existing subscribers.

On the other hand, Wired magazine in June launched an edition for iPad and other tablet users that sold more than 100,000 copies via Apple’s iTunes Store, more than its usual newsstand sales, although that figure has since trailed off.

“[That] should give some indication of how well received [The Daily] idea will be,” said Jeff Orr, an analyst with ABI Research.

iPad Gets a Little iPhonier

 iOS 4.2, the new version of the mobile device operating system Apple pushed out Monday, includes several new features for iPad users — and a few of them are features iPhone owners have been using for some time. The update puts all three types of iOS devices more or less on equal footing in terms of features. In addition, users will now be able to use the Find My iPhone feature for free.

Apple (Nasdaq: AAPL) released iOS 4.2 on Monday, managing to put the update in users’ hands within the month of November. Some users, however, had expected the completed iPhone, iPad and iPod touch update to be released earlier this month.

The delays were reportedly due to bugs that required fixing.

The latest release of Cupertino’s mobile device operating system incorporates several new features, including AirPlay and Game Center for iPad.

It also incorporates the Find My iPhone feature, which is now available free.

Another new feature lets users rent TV episodes directly to the iPad.

Apple also released an Apple TV update, version 4.1, in a move that could be interpreted as injecting power into AppleTV in a bid to fend off Google (Nasdaq: GOOG) TV.

Apple did not respond to requests for comment by press time.

Details of iOS 4.2

The iOS 4.2 update works only with the iPad, the iPhone 3G and later and iPod touches released in late 2009 or afterward with 32 or 64 GB of storage.

For iPad owners, the OS update also lets users organize their apps into folders using drag-and-drop, a feature that iPhone users have already been able to use. The iPad’s Mail feature has a unified inbox, and it offers fast inbox switching and a threaded message view.

Another feature, Game Center, lets iPad users play games online or be matched automatically with new opponents.

The iOS 4.2 update includes AirPlay, a feature that lets users stream music, video and photos wirelessly from their iDevices to Apple TVs. Users can also use AirPlay and AirPort Express to wirelessly stream content to stereos or powered speakers, or directly to AirPlay-enabled speakers. The latter will hit the market soon, Apple disclosed.

Another feature, Find My iPhone, is now available for free as part of iOS 4.2. Previously, users had to sign up for the MobileMe service at $99 per year in order to use this feature.

The OS update lets users rent TV episodes directly on their iPads through the iTunes app. They get 30 days to watch the episode and 48 hours to view it once they begin playback.

Further, iOS 4.2 lets users easily find and highlight specific words and phrases on Web pages in Safari. It has enhanced enterprise support capabilities with increased security and better device management.

Parity With the iPhone

Release 4.2 of iOS lets iPad users multitask, switching between apps on the fly. This feature has been available on the iPhone for some time, so iOS 4.2 unifies the two platforms.

“The major value of iOS 4.2 is bringing iPhone 4 parity to the iPad,” Carl Howe, director of anywhere consumer research at the Yankee Group, told MacNewsWorld. “For the past six months, iPads have had the bigger screens, but lacked many of the features of the iPhone 4. Now, consumers can choose between them based on hardware preferences, not software differences.”

AirPlay Gives You Content Anywhere

AirPlay lets users stream content through their homes wirelessly. The technology will be fully integrated into speaker docks, AV receivers and stereo systems from companies such as Bowers & Wilkins and Denon, Apple said.

AirPlay will likely be used to boost the profile of Apple TV, a product Apple CEO Steve Jobs has repeatedly described as his hobby and one which only began taking off recently after being updated and having its price slashed to US$99.

In launching iOS 4.2, Apple said AirPlay transforms Apple TV into a great accessory for iPad, the iPhone and the iPod touch.

Apple helped things along by releasing its 4.1 update for Apple TV Monday. This will reportedly enable full video streaming and offer spoken menus.

“Airplay is Apple’s way of increasing the value of its ecosystem and further differentiating its ecosystem from those of the competition,” the Yankee Group”s Howe opined.

With Google TV generating considerable excitement, Apple needs to boost Apple TV if it wants to remain a player in the streaming TV game.

Where in the World Is My iDevice?

The Find My iPhone feature, which is available for free in iOS 4.2, may give rise to some controversy for Apple.

The feature lets a user locate an iOS devices if it has been misplaced. Previously, users had to sign up for the MobileMe service, which costs $99 a year.

The newly free offering “is actually the best feature of the upgrade,” the Yankee Group’s Howe said. “My wife and I used that just last Friday — we’d gone to a restaurant for lunch, but then stopped back at my office when she couldn’t find her phone. I used Find My iPhone on MobileMe to discover it was still at the restaurant, displayed a message for the wait staff that we were coming back to get it, and when we went back to collect it, it was waiting for us at the front. That’s not just a product feature; it’s a valuable consumer service.”

Will Apple provide a refund of the fee consumers paid for MobileMe in order to use the Find my iPhone feature?

“MobileMe provides synchronization across multiple devices as well as backing up data in the cloud, and Find My iPhone is only one of its features,” Chris Hazelton, a research director at the 451 Group, told MacNewsWorld.

“While Find My iPhone is arguably the most valuable capability of MobileMe, it’s not likely that Apple will refund users, although it may feel some pressure to reduce the price of MobileMe,” Hazelton said.

MobileMe provides access to email, contacts, calendars and photos.

(basic)Obj C Tutorial Part 2: Why Objective C?

In this section we will learn about the importance of Objective C and “Why Objective C?” is used as programming language to develop applications for Mac System and iPhone.

Why we use objective c? 

It has a lot of features to make a powerful and object oriented program in a easier way. Some are listed below:

1. It is a powerful language, 
2. Easy-to-learn,
3. Object-oriented version of C, 
4. Provide dynamic binding, 
5. Run-time type identification, and persistence
6. Easy to understand code
7. Well organized language


(Basic) Obj C Tuto Part 4 :Objective-C keywords

Here in this section we will know about the keywords used in objective-C language. Objective-C is a superset of C language, so program written in c and C++ should compile as objective-c. It provides some additional keywords, to avoid conflict with keywords in other language it uses ‘@’ at the beginning of keyword. These keyword are called Compiler Directives.

 Directives used to declare and define classes, categories and protocols:

Directive Definition
@interface used to declare of class or interface.
@implementation used to define a class or category.
@protocol used to declare a formal protocol.
@end ends the declaration, definition, category or protocol.

Directive used to specify the visibility of the instance. Default is @protected.

Directive Definition
@private Limits the scope of an instance variable to the class that declares it.
@protected Limits instance variable scope to declaring and inheriting classes.
@public Removes restrictions on the scope of instance variables.

Exception handling directives.

Directive Definition
@try Defines a block within which exceptions can be thrown.
@throw Throws an exception object.
@catch Catches an exception thrown within the preceding @try block.
@finally A block of code that is executed whether exceptions were thrown or not in a @try block.

Directive used for particular purpose.

Directive Definition
@class Declares the names of classes defined elsewhere.
@selector(method_name) It returns the compiled selector that identifies method_name.
@protocol(protocol_name) Returns the protocol_name protocol (an instance of the Protocol class). (@protocol is also valid without (protocol_name) for forward
@encode(type_spec) Yields a character string that encodes the type structure of type_spec.
@”string” Defines a constant NSString object in the current module and
initializes the object with the specified 7-bit ASCII-encoded string.
@”string1″ @”string2″ …
Defines a constant NSString object in the currentmodule. The string
created is the result of concatenating the strings specified in the two
@synchronized() Defines a block of code that must be executed only by one thread
at a time.

Some keywords of Objective-C are not reserved outside. These are…..

in out inout bycopy
byref oneway    

Keyword for memory management in Objective-C 
These are looking as keywords but infact these are methods of root class NSObject.

alloc retain release autorelease

Some other keywords:

1.  bool is a keyword used in objective-C but its value is here YES or NO. In C and C++ it has value either TRUE or FALSE.
2. ‘super’ and ‘self’ can be treated as keywords but self is a hidden parameter to each method and super gives the instructions to the compiler that how to use self differently.

Preprocessor Directives
The preprocessor directives are special notations:

Directive Definition
// This is used to comment a single line.
#import  Like C and C++ it is used to include a file but it doesn’t include more than once.

Infosys to build new facility in Bangalore

Nandita Gurjar, senior vice-president and group head – human resources – Infosys said the company is going anywhere where there is space.

“Last year, we built the Pune facility and it is ready for occupation this year. The decision to locate employees at a particular centre is purely based on capacity at a facility,” said Gurjar.

She said Infosys has been unable to expand its facility in Bangalore because of space constraint.

However, with the availability of land in the Sarjapur area of Bangalore, the company will start building a new facility next year.

Most information technology firms are looking at expanding their centres in Tier II cities to slash their human resource and real estate costs, which tend to be lower in these places.

Gurjar says her company does not benefit in terms employee cost by sending them to Tier II cities because Infosys has uniform pay scales across all centres.

“If we differentiate on salary (for different centres) then people will not be ready
to go to smaller towns,” she said.

On savings on real estate costs, she said Pune did work out cheaper than Bangalore.

Ruby on Rails regains lost performance

The Ruby on Rails 3.0.3 Web development framework was released this week, restoring performance lost when the open source framework was upgraded to Rails 3.x.

The upgrade bolsters the Active Record technology in Rails, which provides the basis for models in Rails applications along with such capabilities as data validation and database independence. “How about some free speed? Well, here you go. Rails 3.0.3 includes a much faster version of Active Record that reclaims the performance lost when we went from Rails 2.3.x to 3.x and then some,” Rails founder David Heinemeier Hansson in a blog post.

Version 3.0.3 also features minor fixes, Hansson said. “So everything just works better and faster. What more can you ask for? Oh, that it’s a drop-in replacement for Rails 3.0 — there are no API changes. You got it Rails 3.0 was released in late-August, offering boosted performance capabilities as a result of a merger with the Merb framework. Cross-site scripting protection by default also was included.
