Hadoop Technology

Introduction:-

       Hadoop is a new technology. Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware. It provides massive storage for any kind of data, processing power and the ability to handle virtually limitless concurrent tasks or jobs.

History:-

        As the World Wide Web grew in the late 1900s and early 2000s, search engines and indexes were created to help locate relevant information amid the text-based content. In the early years, search results were returned by humans. But as the web grew from millions of pages, automation was needed.

Why is Hadoop important?

• Ability to store and process huge amounts of any kind of data, quickly. With data volumes and varieties constantly increasing.
• Computing power.
• Fault tolerance.
• Flexibility.
• Low cost. The open-source framework is free and uses commodity hardware to store large quantities of data.
• Scalability. You can easily grow your system to handle more data simply by adding nodes. Little administration is required.

What are the challenges of using Hadoop?

• MapReduce programming is not a good match for all problems.
• There’s a widely acknowledged talent gap.
• Data security– it is also provide data security for hadoop and big data users.
• Full-fledged data management and governance. Hadoop does not have easy-to-use, full-feature tools for data management, data cleansing, governance and metadata.

How Is Hadoop Being Used?

• low-cost storage and data archive.

  

• Sandbox for discovery and analysis.
• Data Lake.
• Complement your data warehouse.

What is Big Data?

Introduction:

            Big data is a term that describes the large volume of data ` both structured and unstructured ` that inundates a business on a day-to-day basis. But it’s not the amount of data that’s important. It’s what organizations do with the data that matters. Big data can be analyzed for insights that lead to better decisions and strategic business moves for any organizations or company.

History:

            While the term “big data” is relatively new, the act of gathering and storing large amounts of information for eventual analysis is ages old. The concept gained momentum in the early 2000s when industry analyst Doug Laney articulated the now-mainstream definition of big data as the three Vs:

1. Volume:-Organizations collect data from a variety of sources, including business transactions, social media and information from sensor or machine-to-machine data.
2. Velocity:-Data streams in at an unprecedented speed and must be dealt with in a timely manner.
3. Variety:-Data comes in all types of formats ` from structured, numeric data in traditional databases to unstructured text documents, email, video, audio, stock ticker data and financial transactions.

Why Big Data important?

The importance of big data doesn’t revolve around how much data you have, but what you do with it. You can take data from any source and analyze it to find answers that enable 1) cost reductions, 2) time reductions, 3) new product development and optimized offerings, and 4) smart decision making. When you combine big data with high-powered analytic, you can accomplish business-related tasks such as:

• Determining root causes of failures, issues and defects in near-real time.
• Generating coupons at the point of sale based on the customer’s buying habits.
• Recalculating entire risk portfolios in minutes.
• Detecting fraudulent behavior before it affects your organization

Who uses Big Data?

Today’s life we have large amount of information to gathering and storing but that doesn’t matter how much amount of data you have.

Below points shows where big data is important-

• Education
• Government
• Healthcare
• Banking
• Manufacturing
• Retail etc.

Google now becomes strict against android spammer

Number One Search Engine Google has now introduced stricter policies for application developers & managers to stop  malicious apps on its Androidplatform.

Policy changes for apps submitted to the Google Play app store include new guidelines on app renaming, a ban on apps that disclose personal information without permission and more details on the payment policy. “We are constantly striving to make Google Play a great community for developers and consumers,” the Android team wrote in a letter to app developers.

“This requires us to update our policies when we launch new features, like subscription billing, and also when we see unhealthy behavior, like deceptive app names and spammy notifications,” the letter added. According to the Telegraph, Google’s new terms tell developers ‘not to pretend to be someone else’.

“And don’t represent that your app is authorized by or produced by another company or organization if that is not the case,” the rules say.

Developers/Programmers  are also notified that applications that introduce security vulnerabilities or ‘harm user devices’ will not be permitted.

India planning to send jaintheme in mars | Mission 2013

India | The second most developing  country  planning to send jaintheme to Mars in 2013 . This jaintheme will help us to monitor small part of India .

Rocket will launch from the south east part of India under the supervision of Indian Space Research Organization .If this mission completes ,India will become sixth county to do this after US,Russia,Europe,China and Japan.

The Rocket is expected to be launched from India Spaceport “Sriharikota” in AndraPradesh and may take up to 360 days to reach Mar.

In Addition to this , India is planning to launch one more rocket in mars to study atmosphere of Mars .

Government of India is  giving full support to ISRO for this project and said that if this mission failed , they will support again in 2016 and 2018  for the same cause .

Hope ,Prime Minister Dr. Manmohan Singh will help our space centers to grow as NASA .

32 bit versus 64 bit ! which is faster and secured?

32 bit v/s 64 bit,which is faster and secured?

Microsoft launched its first 64 -bit operating system on  windows vista and windows 7  along with all latest security patches.But it is interesting to inform you that 64-bit processor exist early 1970’s in supercomputers.In 2003 ,they were introduced in personal computers.

Many  Programmers now works on 64-bit operating systems because  now the future is 64-bit.but,since now,35% of applications(B,C grade) are not fully compatible with 64 bits.But whether adobe reader,Microsoft Office 2003,2007,2010 ,dreamweaver,browsers(chrome,firefox),Nokia PC-suite are fully supported by 64-bits operating systems because they all are A-grade.

The meaning of 64 -bit is that it has 64 bit register which allows once at an  instant to processes 64 bit data with multiply ram size for  performance.A common misconception is that 64-bit architectures are no better than 32-bit architectures unless the computer has more than 4 GB of main memory. This is not entirely true.

I am using 1 gb ram laptop(IBM) with 64-bit processor

and all works fine with better performance than 32 bit.

Advantages in using Windows 64-bit Operating systems:

1.Microsoft has enhanced security in Windows 64-bit that is not available in 32-bit.Latest security updates and Patches boost your security and performance.

2.Hardware-based Data Execution Prevention (DEP): Modern CPUs are now supporting hardware-based DEP but only 64-bit of Windows supports hardware-based DEP.

3.Kernel Patch Protection (PatchGuard): One type of malware is called Rootkit. If you have 64-bit edition of Windows, you can enjoy protection against kernel-based rootkits. You can also avoid BSOD if you have 64-bit edition of Windows because PatchGuard does not allow any drivers to modify the kernel in Windows.

4.Driver Signing: 64-bit of Windows will only allow installation of device drivers that is digitally signed by its developer.
Disadvantages of using Windows 64-bit Operating system:

1.All softwares/applications are not fully supported by 64-bit operating system.

2.Allow restict for making illegal experiments on windows files.Therefore ,you now not allow to experiment on windows graphics,drivers to make it compatible.

3.Many Internet Security not compatible in real sense:I think you are not well-aware of the fact that even in market many antivirus make promises that they are 64 – bit compatible.But in real sense,only 40% of the total antivirus in the world are compatible(100%) rest 60-90%.Its create Problems in your performance,speed and security.so,choose correct one.
