பிக் டேட்டா என்றால் என்ன? டேட்டாவிலேயே பெரிய அப்பாடக்கரா?

வண்டிவண்டியாய் டேட்டா இருந்தால் மட்டுமே அதனை பிக் டேட்டா என்று சொல்லிவிட முடியாது. பிக் டேட்டாவிற்கு நான்கு குணாதிசயங்கள் உண்டு. எளிதில் புரிவதற்கான உதாரணங்கள் சிலவற்றை தந்துள்ளேன். டேட்டா கோட்பாடுகள் இடிக்கின்றது என யாரும் வரிந்துகட்டிக்கொண்டு சண்டைக்கு வரக்கூடாது.

எது பிக்டேட்டா ?

சென்னையில் வாழும் மனிதர்களின் பெயர்களை மட்டும் டேட்டா பேஸில் ஏற்றிவிட்டால் அது பிக்-டேட்டாவாகிவிடாது. பரபரப்பான சென்ட்ரல் ரயில் நிலையத்தின் வாசலில் ஒரு ஸ்கேனர் வைத்து எத்தனை பேர் ரயில் நிலையத்தின் உள்ளேயும் வெளியேயும் சென்றார்கள் என்று கவுன்ட்டிங் செய்து பதிந்தால் அது பிக்-டேட்டாவாகாது.

அதிகாலையில் புறப்படத்தயாராக இருக்கும் ஒரு ரயிலில் எத்தனை பேர் செய்தித்தாள் விற்கும் பையனிடம் நாளிதழ்களை வாங்கினார்கள் என்று பதிந்து வைத்தால் அதுவும் பிக்டேட்டாவாகாது. அப்படி நாளிதழ்களை வாங்கினவர்கள் அனைவருமே அந்த நாளிதழ்களின் சந்தாதாரர்களாக இருப்பார்கள் என்று நாமாகவே எழுதிவைத்துக்கொண்டால் அதுவும் பிக்டேட்டாவாகாது.

பிக் டேட்டா என்ற தகுதியைப் பெற முக்கியமான நான்கு குணாதிசயங்கள் வேண்டும். அதிகமான பதிவுகள், அதிவேகமான பதிவுகள், பலவிதமான பதிவுகள், உண்மையான உபயோகத்தன்மையுள்ள பதிவுகள் என்ற நான்கும் பிக்டேட்டாவை விவரிக்கும் குணாதிசயங்கள். [ஆங்கிலத்தில் 4 V’s என்று சொல்லும் - Volume, Velocity, Variety and Veracity]. இந்த நான்கு குணங்களைக் கொண்ட பிக்டேட்டாவை பிசினஸ் உபயோகத்திற்கு கொண்டுவருவது மற்றுமொறு ’V’ என்ற Value எனும் ஐந்தாவது V.

மதிப்புதான் உயிர்

எல்லா குணங்களும் இருந்தும் அந்த டேட்டாவில் மதிப்பு இல்லாவிட்டால் என்ன உபயோகம் இருக்கப்போகின்றது? பிசினஸிற்கு வேல்யுதானே உயிர். இந்த நான்கு குணங்களைக்கொண்ட பிக்டேட்டாவை வைத்துக்கொண்டு எந்தவகையான பிசினஸ் மதிப்புகளை கூட்ட முடியும் என்பதுதான் அது.

இந்தக் குணாதிசயங்களை வைத்துக்கொண்டு மேலே சொன்ன உதாரணங்களை அலசுவோம். சென்னையில் வாழும் நபர்களின் பெயரை தொடர்ந்து முகவரி, கைபேசி எண், வீட்டிலிருக்கும் எரிவாயு கனெக்‌ஷன் கம்பெனியில் ஆரம்பித்து டிஷ் டீவி, போன், கம்ப்யூட்டர், சோபா செட் வாங்கிய கடை, ரெகுலராய் நகை வாங்கும் கடை, பிரியப்பட்டு செல்லும் சினிமா தியேட்டர், ரெஸ்ட்டாரெண்ட், துணிக்கடை, வாங்கும் பனியனின் பிராண்ட், வைத்திருக்கும் டூ வீலர், வாரா வாரம் போகும் கோவில், மருந்துவாங்கும் கடை என ஜாதகமே இருந்தால் அது பிக்டேட்டாவிற்கு முதல் தகுதியை பெற்றுவிட்ட ஒன்று.

சென்ட்ரல் ரயில் நிலையத்திற்கு உள்ளேயும் வெளியேயும் சென்றவர்களின் பயணத்திட்டம் எத்தனை நாட்கள், கையில் இருக்கும் லக்கேஜின் (பெட்டி/கைப்பை) பிராண்ட், எங்கே தங்கினார் / தங்கப்போகின்றார், டாக்ஸி பிடிப்பாரா? ஏற்கனவே கார் காத்திருக்கின்றதா? ரிட்டர்ன் ஜர்னி டிக்கெட் இருக்கின்றதா? அடிக்கடி சென்னை வருபவரா? மாமாங்கத்துக்கும் ஒரு முறையா? என பயணத்தை தாண்டிய பல டேட்டாக்கள் அந்த நபர் சென்ட்ரல் ரயில் நிலைய வாயிலை கடக்கும் நொடிப்பொழுதில் பதிவு செய்ய முடிந்தால் அதுவும் பிக்-டேட்டாவுக்கு தகுதிபெறும் மற்றொரு விஷயமாகும்.

புறப்படத்தயாராக இருக்கும் ரயில் வண்டியில் பேப்பர் வாங்கினவர்கள் எத்தனை பேர் என்ற விவரத்தைத் தாண்டி என்ன கோச், நாளிதழ், வாராந்திர இதழ்கள், புத்தகம், வாட்டர் பாட்டில், டிபன், கடலை மிட்டாய், வறுகடலை, டூத் பேஸ்ட், வாழைப்பழம் போன்றவை, தனிநபர் பயணமா, குடும்பத்துடன், அலுவலக பணியாளர்களுடன் பயணமா?, ரயிலில் வாங்கிய நாளிதழ்/வாராந்திர இதழ்களை அவர் தொடர்ந்து வாங்குகின்றாரா? அல்லது வேறு நாளிதழ்/புத்தகங்களை வாங்குகின்றாரா? போன்ற இன்னபிற டேட்டாக்களும் பதிவு செய்யப்பட்டால் அது பிக்-டேட்டாவின் குணாதிசயத்தை சற்றே உள்ளடக்கியது எனலாம்.

இந்த உதாரண டேட்டா கலெக்‌ஷனில் வரும் டேட்டாவினால் ஏதாவது ஒரு முக்கிய உபயோகமும் இருக்கவேண்டும். பிறந்த ஊர், முதலில் படம் பார்த்த டெண்டு கொட்டகையின் பெயர் எனத் தேவையில்லாத டேட்டாக்கள் பெருமளவில் இருந்தால் அது பிக்டேட்டாவாகாது.

வால்யூம் ரகசியம்

அட! இதெல்லாம்தான் டேட்டாவா? இதையெல்லாம் வைத்துக்கொண்டு என்ன செய்ய முடியும் என்ற எண்ணம் உங்கள் மனதில் தோன்றலாம். இவை டேட்டாவின் உதாரணங்கள் மட்டுமே. டேட்டாக்கள் தொடர்ச்சியாகவும் வேகமாகவும் அலசப்படும் போதுதான் பெரியபெரிய உண்மைகள் புலப்படுகின்றன. உதாரணத்திற்கு, நீங்கள் கிரெடிட் கார்ட் வைத்திருக்கின்றீர்கள்.

வெறுமனே செலவுகளை கணக்கு வைத்து வசூலைச் செய்யாமல் பல்வேறு அனலிடிக்ஸ்களை கிரெடிட்கார்டு நிறுவனங்கள் உபயோகிக்கின்றன. எப்போதும் இல்லாத அளவில் அடிக்கடி பாரில் உங்கள் கிரெடிட் கார்ட் உபயோகிக்கப்படுகின்றதா? ஏதோ சோகத்திலோ அல்லது ஊதாரித்தனத்திலோ திரியும் நம்ம ஆளு பணம் கட்டாமல் போவதற்கு வாய்ப்பு அதிகம் உள்ளது என்று கிரெடிட்கார்ட் நிறுவனம் அனலிடிக்ஸ் மூலம் புரிந்துகொள்கின்றது.

Swift: A New Programming Language Introduced by Apple For iOS and OS X Development

Swift is an object-oriented programming language for iOS and OS X development which is recently introduced by Apple at its WWDC 2014. It is intended to coexist with Objective-C, the current programming language for Apple operating systems. Swift is designed to be more resilient against erroneous code. It is built with the LLVM compiler.

Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works. On June 2, 2014, the WWDC conference app became the first publicly released Swift app.

Example code

let people = ["Anna": 67, "Beto": 8, "Jack": 33, "Sam": 25]
for (name, age) in people {
println("\(name) is \(age) years old.")
}

Some awesome features of Swift Programming Language

Safe 

Swift pairs increased type safety with type inference, restricts direct access to pointers, and automatically manages memory—making it easy to create secure, stable software.

Modern 

Swift includes optionals, generics, tuples, and other modern language features. Inspired by and improving upon Objective-C. Swift code feels natural to read and write.

Powerful 

Take advantage of powerful pattern matching in Swift to write simple, expressive code. Format strings naturally with string interpolation. Use frameworks like Foundation and UIKit directly from Swift.

Interactive 

Use playgrounds to experiment with new technologies, analyze problems, and prototype user interfaces

Fast 

The Swift compiler applies advanced code analysis to tune your code for performance, letting you focus on writing great apps instead of on implementing complex optimizations.

Why is My PC Crashing?

     Nothing can put a damper on productivity quite like a computer that crashes on a regular basis. Sometimes, a crash is preceded by the dreaded “blue screen of death” or another warning; other times, a computer simply shuts off without any warning at all. In either case, the end result is a whole lot of frustration, aggravation and lost work. If your computer has been crashing frequently, you’d probably like to put an end to it. Unfortunately, getting to the bottom of things if often easier said than done. The following tips about improving your computer’s performance, though, are excellent places to begin.

Possibility #1: Corrupted System Registry Files

     Every Windows-based PC has something called a Windows registry. The registry contains several files that are integral to the performance and operation of your computer. Over time, some of those files can become corrupted, be misplaced or get lost altogether. When that happens, the system registry becomes compromised – and frequent crashes are all-too-common symptoms. The best way to rule this possibility in or out is by running a Windows registry cleaning program. Such programs scan your Windows registry for problems then automatically make repairs. If you run a registry cleaner and the crashes persist, they are probably being caused by a different issue.

Possibility #2: Disorganized Files

     Windows operating systems handle file organization in a way that isn’t very intuitive. Basically, they break files up and fit them into gaps in the computer’s memory. As time goes by, these disorganized files can prompt frequent crashes. Luckily, a great optimization solution is built right into Windows-based PCs: the disk defragmentation utility. Although its location on a computer varies, you can generally locate it within the System and Security section inside the Control Panel. By running a defrag once every few months, you may be able to keep those pesky computer crashes at bay.

Possibility #3: Malicious Software

     Malicious software can take many different forms. Sometimes, it’s a virus that is accidentally unleashed after opening a strange email; other times, its adware that tags along with other information that is automatically downloaded from a website. Whatever type it is, there’s no question that malicious software can wreak havoc on a computer’s performance. Happily, there are many topnotch programs out there that regularly scan your computer for the presence of such problems – and that help guard against them, too. Buy one, install it and use it regularly; your crash issues may come to an end.

Possibility #4: Too Little Available Memory

     When you buy a new computer, it feels like there’s no end to the amount of memory that it has. Of course, this isn’t true at all. As never-ending as the available memory on your PC may initially seem, the fact is that it can be depleted with incredible speed. You can find out for sure by checking the information within “My Computer.” If it appears that your available memory is low, you can use a PC cleanup program to remove unnecessary files; such programs remove things like temporary Internet files and other file debris that can suck away much-needed memory.

Possibility #5: Overheating

     If you’ve run through all of the preceding possibilities and continue experiencing frequent crashes, a hardware issue could be to blame. An easy one to rule out is overheating. A computer’s CPU, or central processing unit, includes a fan that is designed to keep it running cool. Sometimes, the fan wears down and doesn’t work as efficiently; other times, it’s just not able to handle the work that your computer has to do. In either case, buying a bigger, better fan isn’t very expensive. If it puts an end to your PC crashing problem, it will have been more than worth it. Don’t Put Up with Frequent Crashes!

    As discussed, frequent computer crashes can be triggered by a wide variety of issues. Luckily, many of these issues are relatively easy to remedy. Work your way through the preceding list; chances are, you’ll be able to pinpoint the problem and put an effective cure to work. Nine times out of ten, a computer simply needs a little bit of routine maintenance to get it back on track again. In the future, keep these points in mind. Any time you buy a new computer, keep up with its basic maintenance right from the get-go. By doing that, you could avoid “blue screen of death” and crashing problems altogether – and that’s something that you’re bound to appreciate!

Nokia Finally Releases Its First Android Based SmartPhone. Here Is All About It

     For those of you who know the finer details of their smartphones, you’ll know that Nokia’s smartphones have been running different variants of Windows OS for mobile devices. But this year the Finnish company took things in a completely different direction by unveiling their first series of Android smartphones at the 2014 Mobile World Congress

The company has revealed it’s new Nokia X series of Android smartphones which will run Android OS, with a few modifications. This Nokia X is not only the name of the smartphone series but also the name of the operating system.

This “three way mashup” uses the Android 4.1 as a base and adds element of the Asha and Windows phone lineups creating an OS that can run Android apps, although with no access to the Play Store since Nokia will be curating the user’s app experience

Currently the range will have three phones spanned over three different price ranges. The lowest in the range is the Nokia X, a phone with a 4-inch screen and a dual core 1GHz Snapdragon processor. The next in line is the Nokia X+, which has a larger internal memory and a slot for a micro SD card. The phone at the high-end, the Nokia XL, is also the largest (as the name suggests) and a 5-inch screen, a 5 megapixel rear camera and a 2 megapixel front camera.

This new development by the world famous mobile company is certainly amazing, especially since Windows and Google have been competitors in the tech market for years now. But the X series of phones will give users a slightly different experience from what they would be expecting upon first hearing the phrase “Android Nokia”.

Facebook Buying WhatsApp for $19B.

Facebook Buying WhatsApp for $19B.

Facebook is buying mobile messaging service WhatsApp for $19 billion in cash and stock, by far the company's largest acquisition and bigger than any that Google, Microsoft or Apple have ever done.

The world's biggest social networking company said Wednesday that it is paying $12 billion in Facebook stock and $4 billion in cash for WhatsApp. In addition, the app's founders and employees — 55 in all — will be granted restricted stock worth $3 billion that will vest over four years after the deal closes.

The deal translates to roughly 11 percent of Facebook's market value. In comparison, Google's biggest deal was its $12.5 billion purchase of Motorola Mobility, while Microsoft's largest was Skype at $8.5 billion. Apple, meanwhile, has never done a deal above $1 billion.

The deal's price tag stunned Gartner analyst Brian Blau. "I am not surprised they went after WhatsApp, but the amount is staggering," he said.

Facebook likely prizes WhatsApp for its audience of teenagers and young adults who are increasingly using the service to engage in online conversations outside of Facebook, which has evolved into a more mainstream hangout inhabited by their parents, grandparents and even their bosses at work.

WhatsApp also has a broad global audience. Facebook CEO Mark Zuckerberg said the service "doesn't get as much attention in the U.S. as it deserves because its community started off growing in Europe, India and Latin America. But WhatsApp is a very important and valuable worldwide communication network. In fact, WhatsApp is the only widely used app we've ever seen that has more engagement and a higher percent of people using it daily than Facebook itself."

Microsoft appoints India-born Satya Nadella as CEO

     During this time of transformation, there is no better person to lead Microsoft than Satya Nadella,” said Microsoft co-founder Bill Gates.

Hyderabad native Satya Nadella (46) is the new CEO of Internet giant Microsoft, the company announced on Tuesday.

“During this time of transformation, there is no better person to lead Microsoft than Satya Nadella,” said Bill Gates, Microsoft’s founder and Chairman of the Board, adding, “Satya is a proven leader with hard-core engineering skills, business vision and the ability to bring people together.”

After a selection period that saw numerous outside candidates drop off, the Microsoft Board the Microsoft Board signalled its intention to focus on innovation by selecting the man credited with developing the company's cloud computing and Bing search engine businesses.

In his email to Microsoft employees on his first day as CEO Mr. Nadella said, “Today is a very humbling day for me. It reminds me of my very first day at Microsoft, 22 years ago… I saw then how clearly we empower people to do magical things with our creations and ultimately make the world a better place.”

While some have argued that Microsoft was slow to respond to the shift towards cloud computing, conceding a lead to others such as Google and Amazon, Mr. Nadella underscored his intention to reverse this saying, “Our industry does not respect tradition – it only respects innovation.”

Mr. Nadella who holds a bachelor’s degree in electrical engineering from Manipal University, a master’s in computer science from the University of Wisconsin, and an MBA from the University of Chicago, joined Microsoft in 1992.

His long career as a Microsoft insider saw him promoted to numerous high-level positions before he was appointed Executive Vice President (VP) for the cloud and enterprise group in 2012.

He is married and has three children.

End of Windows xp ???? - 8th April 2014

Microsoft to stop support for Windows XP on April 8, 2014

Microsoft’s one of the most popular operating system running desktop computer systems, will stop getting any support from the company after April 2014.

Microsoft has provided support for Windows XP for the past 11 years. But now the time has come for us, along with our hardware and software partners, to invest our resources toward supporting more recent technologies so that we can continue to deliver great new experiences.

As a result, after April 8, 2014, technical assistance for Windows XP will no longer be available, including automatic updates that help protect your PC. Microsoft will also stop providing Microsoft Security Essentials for download on Windows XP on this date.

If you continue to use Windows XP after support ends, your computer will still work but it might become more vulnerable to security risks and viruses. Also, as more software and hardware manufacturers continue to optimize for more recent versions of Windows, you can expect to encounter greater numbers of apps and devices that do not work with Windows XP.

For those who are on this old version of operating system, they need to shift to the new OS soon.

Different types of servers. . . we must know this. .

12 Type Of Servers And What They Do!

1. Real-Time Communication Servers
Also known as chat servers or IRC, and sometimes known as instant messaging (IM) servers, these servers are meant to allow huge number users to exchange information instantly.

2. FTP Servers
This is one of the oldest of the Internet services available. The FTP or File Transfer Protocol allows the users to securely transfer one or more files of any size between two computers.

3. Collaboration Servers
In many ways, collaboration software, once called 'groupware,' demonstrates the original power of the Web. Collaboration software designed to enable users to collaborate, regardless of location, via the Internet or a corporate intranet and to work together in a virtual atmosphere.

4. List Servers
List servers lets users better manage their mass mailing lists like open interactive discussions or one-way lists to deliver newsletters, announcements or advertising.

5. Telnet Servers
The Telnet server lets the users on to a host computer control and work on remote computers.

6. Web Servers
At its core, a Web server serves static content to a Web browser by loading a file from a disk and serving it across the network to a user's Web browser. This entire exchange is mediated by the browser and server talking to each other using HTTP.

7. Virtual Servers
A virtual server is a web server which shares its resources with multiple users. It's another way of saying that multiple web sites share the resources of one server.

8. Proxy Servers
Proxy server is a server which acts as an intermediary for requests between the users and the servers. Client connects to the proxy server and the proxy server evaluates the requests sent by the users simplifies them and control their complexities.

9. Mail Servers
Mail servers help in moving and storing the e-mail over a network via LANs and WANs or across the Internet.

10. Server Platforms
Normally used in same context with that of operating systems, server platforms are the platforms that are under the hardware or software of a system and the hence in the engine that drives the server.

11. Open Source Servers
Similar to server platforms, Open source server are referred to the underlying open source operating system used in the IT infrastructures of the companies.

12. Application Servers
Application servers are a type of middleware which connects the database servers and the app users.

Microsoft launches women’s safety app

HYDERABAD: Microsoft India today said it is introducing Guardian, a new safety application (app), available exclusively for Windows phone users in India.

Incidents such as ‘Nirbhaya’ prompted the global IT giant to come out with an app aiming at protecting women, Microsoft-IT India managing director Raj Biyani said.

Explaining its features, Biyani said Guardian enables users to switch on a ‘track me’ feature in the app that lets friends and family track them in real time using Microsoft Windows Azure cloud services and Bing Map APIs. Guardian users can call for help through an ‘SOS’ alert button and also connect to security agencies, police and hospitals easily via this app in times of distress.

The app was developed over six months by a group of enthusiastic Microsoft employees in India, within the Microsoft Garage. Microsoft Garage is a global employee innovation initiative that gives Microsoft employees an outlet to explore ideas in their free time, Biyani said.

“Our employees wanted to do something to enable people to feel safer in our cities. So they used their spare time to develop Guardian. It is a robust personal security app with more safety features and capabilities than any other comparable app available to Indian smartphone users today,” Biyani told reporters after launching the app.

To use Guardian effectively, users need to add the names of friends, family members and security groups to the settings and in an emergency situation, the app can be used to alert them, via the SOS button. All the user has to do is tap the SOS button, a Microsoft official said.

“The phone then sends a distress SMS to all buddy mobiles, notifying them of the emergency along with location details. At the same time the SOS button also sends emails to buddy email IDs and posts to private Facebook groups, if registered,” the official said.

Guardian uses Microsoft Windows Azure cloud services and Bing Map APIs extensively and can help security authorities and medical teams track the user. The phone can be traced even if it is broken. The application is capable of one touch video recording that may be used later as evidence, the official added.
