PayPal will be opening its incubation centre Start Tank in Bangalore next year to identify and nurture startups in Karnataka. It will eventually expand to Shangai and Singapore. The upcoming incubation centre will provide cost and obligation-free environment for selected startups to evolve. Currently Start Tank has its presence in Chennai, London and Boston.

The incubation centre will be hosted inside Bangalore’s development centre. According to Anupam Pahuja, General Manager of PayPal Development Centres this would help the startup ecosystem in India. It will house early-stage tech-centric startups from Karnataka for an average of 12 months and provide access to global mentors, angel investors and venture capitalists. It will help foster entrepreneurial spirit and focus on building an ecosystem that nurtures entrepreneurship and innovation.

PayPal launched it’s incubation centre in Chennai last October in partnership with The Indus Entrepreneurs (TiE). It currently houses six technology startups DoPartTimes, Kobster, Fantain, Hey Feedback, Clockwork Interviews and Demach Software.

“We are grateful to PayPal for constantly giving us mentorship support, technical expertise, and the business connects for customer acquisition. When our mobile application was in the pre-beta stage, we launched it internally among the PayPal employees, which helped us assess the app for technology and sustenance,” Aravind Ramachandran, co-founder of Fantain, a sports fan engagement and management company

PayPal was also recently recognized for providing world-class incubation space and support for entrepreneurial community. It earned the company accolade “Ecosystem Enablement – Startups” category at the 2014 Zinnov Awards in Bangalore.

“TiE Chennai is proud to be associated with PayPal in its mission to create a vibrant startup ecosystem. The incubation center created in PayPal facility – mentored by TiE Charter members and PayPal executives has made a difference to young entrepreneurs. Our dream is to the see the emergence of recognizable brands from Start Tank,” Lakshmi Narayanan, President, TiE Chennai, said.

Ms. Marianne Lake, the chief financial officer of JPMorgan Chase , the largest card issuer in the country said in a financial conference at the New York headquarters that she was excited about the company’s partnership with the technology giant Apple following the announcement of Apple Pay by Timothy D. Cook on Oct. 14th  at Cupertino, California. The involvement of JPMorgan Chase in Apple Pay was under the wraps till the debut of Apple Pay was finally put on the table. She was delighted about the company’s investment and involvement in Apple Pay since it has the potential to transform payments in the long run.

The newly announced Chase – Apple partnership allows the Chase customers to make a purchase with the touch of a finger. The Chase customers can make payments in-store and purchases within the app at selected merchants. The ubiquity of Apple Pay combined with the reach of Chase is designed to sway the consumer’s choice and dramatically accelerate the adoption of mobile payments.


The upcoming Apple Pay feature is expected to assume a central role in the financial universe and influence the customer’s default choice for payments. It is the future, a game-changer at the leading edge of the payments trend having the potential to accelerate the adoption of mobile payments. Will this threaten the existing players in the ecosystem and replace them altogether?  What makes the partnership with Apple so attractive? Apple Pay received overwhelmingly positive reception from the merchants. Apple’s penetration is such. There has been enormous pressure to make technological improvements in the current digital payments which is on the verge of collapse. The magnetic stripe authentication is stone age.  Today’s is the tokenization – getting to the heart of Apple’s announcement. This takes out the need for the merchant to know your credit card numbers. The biggest retailers in the industry like McDonalds have signed up for this initiative.

Many rival mobile wallets like Google checkout have tried similar initiatives and failed in the past.  This should start changing fairly quickly with the next generation iPhone 6 and iPhone 6 plus featuring the latest technology. Will Apple succeed in persuading the merchants to adopt mobile payments?

  1. 220,000 US businesses apparently support NFC-based contactless payments .The merchants need to install a hardware that can read the wireless signal carrying the payment information.
  2. The simple one-touch mobile payment flow is designed to sway the consumer’s choice. It’s incredibly easy to use – tap the device to make a purchase
  3. Biometrically authenticated mobile transaction can reduce fraud
  4. Apple’s clout with the retailers and sheer size of the market can lead to swift adoption of mobile payments and grab lion’s share of the market
  5. Apple pay charges a lower rate compared to the credit card networks


Thus the long awaited payment entry of Apple has sparked a healthy competition among the financial institutions. The uptake of mobile payments has been sluggish in the past. We gotta start somewhere and Apple has done it the right way with the end users.

The Battle Hack world finals took place at the PayPal headquarters (San Jose) on November 16th, 17th. The global hackathon spanning six countries required the teams to code the best application they can within 24 hours utilizing the PayPal REST API along with other sponsor services which includes the Twilio, Nokia, Windows Azure and SendGrid. The first-ever inaugural marks the beginning of PayPal’s quest to find the best hackers across 10 cities on earth. The teams are judged based on the code/technology, the quality of the idea and the overall experience. The Director of PayPal Developer Network John Lunn announced that 2000 teams participated in the event and the team from Moscow emerged winner of Battle Hack grand prize $100,000 for the Donate Now application.

John Lunn, said “We truly believe that developers can help change the world. The goal of our Battle Hack program is to find the best and brightest developers across the globe that could do just that. The response from our inaugural Battle Hack competition has been overwhelming, with several cities selling out and bringing talented hackers.”



Donate Now app from Moscow (Grand Prize Winner)

This project resulted in an Android app that uses Bluetooth Low Energy (BLE) technology and PayPal to allow anyone to donate money instantly for causes like natural disasters, blood-drive.

RunPal from Tel Aviv (Second Place)

The team developed RunPal to help people stick to their fitness program. With this app, you are paired with a random user and form a monetary-based pact where each commit to a specifc running program and the person who fails to keep up will forfeit his share. This app uses RunKeeper’s health graph, PayPal API, Twilio’s SMS messaging while also building on top of Appcelerator’s Titanium platform

Kiva-like service from Miami (Third Place)

This team streamlines the loan process which allows a lender to lend funds without even coming in contact with the borrower. Interested lenders can use the app to input how much they can provide and the terms of the deal. If the terms match the credit score, those that need funds will select from those agreements. All payments are handled by PayPal. from Berlin (Finalist)

This team created an app called which enables to calculate wages for hourly/seasonal workers who work only for specific periods of time. It gives the capability to list the workers in a mobile app allowing administrators to manage the number of hours worked. The system calculates the pay based on the specific hourly wage of the worker and utilizes PayPal to process payments to each worker.

Get Trucked App from Washington DC (Finalist)

The Get Trucked app allows the mobile food vendors to find new locations and grow their customer base. Its like a kickstarter app for food trucks that lets the interested consumers to put down money to entice the vendors. Everyday they could monitor where the demand is and when the vendor selects the location, the money put in is committed, meaning they will be guaranteed a certain amount that day.

The customers get an email notification via SendGrid that the vendor is coming to their location and the transactions are managed through the Get Trucked’s Microsoft Azure instance.

Disaster relief app from Austin (Finalist)

Jeff Linwood developed a disaster relief fund raising platform that would help raise funds in the even of a disaster. He was inspired by the disaster that happened in Philippines and came up with the most utilitarian app that would help people post status, organize events and raise funds.

This app allows photos and YouTube videos to be embedded and can send SMS powered by Twilio. It uses Send Grid to allow people to communicate via email. These capabilities were implemented considering the fact that people in disaster can’t download an app- they just need help.

Skillfully Made from New York (Finalist)

This team created an app called Skillfully Made that will create new stores anywhere without having to worry about physical location. The iOS and Android app utilizes a QR code scanner that displays the product and enables customization to take place in real-time. The item can then be purchased through PayPal.

By Now from Barcelona (Finalist)

This group created By Now, an app that allows users to scan any product and purchase it. If you’re going to a store, but it closes right before you get there. You see the item in the window and want to know where else you can find it. By Now lets you snap a photo, then processes it to determine how much it costs, and a location.

TapIt from London (Finalist)

The service TapIt utlizes Near Field Communications (NFC) or Bluetooth Low Energy (BLE) stickers to scan information of a particular product and make a purchase right from the mobile phone

Xbox Kinect from Seattle (Finalist)

The team from seattle created an app centered around shopping for clothes using Xbox Kinect. The users can “virtually try on” the clothes while making customizations. They can take a photo using Kinect and share with their friends to help with the selection process. In the end, a QR code is displayed that users can scan using Windows phone device to make purchase using PayPal’s

Following the competition, PayPal’s Marcus said that the competition was all about finding the best hackers to help innovate the company’s platform. He had a vision for the company whereby the core product of the company will become the payment operating system for the technology of tomorrow.



This article presents two simple steps to place your eclipse workspace under GIT. EGIT is a plugin that allows you to use GIT directly within the Eclipse IDE.

Step1: Installation of EGIT

Navigate to Help  –> Install New Software



Type the URL from which the EGIT could be downloaded. Then, click select all and next.



Then Deselect All and select only “Eclipse Egit” and click on next.


After installation of EGIT, we need to configure GIT on Eclipse


Step2:  Configure your Eclipse project to use GIT

Right click on your project in Eclipse. In the context menu, Choose Team –> Share Project



Then, select GIT in the Share Project menu


Then enter the name of your project and create a new GIT repository for the project


To view your project as a GIT repository within the Eclipse IDE, navigate to Windows –> Show View –> GIT –> GIT Repositories


Now you can see your project placed under GIT version control and apply all the GIT commands from your Eclipse IDE!

Here are the frequent GIT merge conflict horror stories one might encounter when one pulls the latest code changes or when the project code is rebased. If you are using GIT bash, its quite easy to configure the GIT environment with a visual GUI tool called DiffMerge that helps you clearly see the lines of code causing the conflict and resolve the merge conflict with a “single click”.


Merge conflicts while doing git pull
Output 1:

git pull
Enter passphrase for key '/c/Users/arvenkataraman/.ssh/id_rsa':
Auto-merging testSuite/sample.xml
CONFLICT (content): Merge conflict in testSuite/sample.xml
Automatic merge failed; fix conflicts and then commit the result.

Output 2:

git pull --rebase
U       testSuite/sample1.xml
U       testSuite/sample2.xml
U       testSuite/sample3.xml
M       testSuite/sample4.xml
U       testSuite/sample5.xml
U       testSuite/sample6.xml
U       testSuite/sample7.xml
M       testSuite/sample8.xml
M       testSuite/sample9.xml
Pull is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm '
as appropriate to mark resolution, or use 'git commit -a'.

Output 3:

git pull
Falling back to patching base and 3-way merge...
Auto-merging testSuite/sample.xml
CONFLICT (content): Merge conflict in testSuite/ sample.xml 
Auto-merging testSuite/sample2.xml
CONFLICT (content): Merge conflict in testSuite/ sample2.xml 
Auto-merging testSuite/sample3.xml
CONFLICT (content): Merge conflict in testSuite/ sample3.xml
Failed to merge in the changes.
Patch failed at 0001 test changes


Step 1: Download DiffMerge tool

The SourceGear DiffMerge tool could be downloaded from the below location:

Step 2: Configure GIT to use DiffMerge tool

Open GIT Bash and navigate to the GIT repository. Then give the below commands to configure GIT with the downloaded DiffMerge tool

git config --global merge.tool diffmerge
git config --global mergetool.diffmerge.cmd "C:/\"Program Files\"/\"SourceGear\"/Common/DiffMerge/sgdm.exe --merge --result=\$MERGED \$LOCAL \$BASE \$REMOTE"
git config --global mergetool.diffmerge.trustExitCode true

Step 3: Invoke DiffMerge from GIT bash


If the git pull command doesn’t succeed due to merge conflict, please give the below command:

git difftool

The DiffMerge opens up as below with automatically selected merge conflict files for comparison

Step 4: Shift the highlighted piece of code to resolve the merge conflict

On the top of the DiffMerge tool there is an arrow to apply changes from the right to left:
step2 DiffMerge for merge conflict
The files are displayed side-by-side for comparision and the differential piece of code to be merged is highlighted in violet color:
step3 Merge changes
Select the piece of code highlighted and click on the “apply changes from the right” arrow at the top. After merge the code will look like below:
step4 After merge

Similarly we could resolve all the merge conflicts with a single click. It is a lot more easier since this is a visual tool for merge.

Here are the steps to do extensive debugging of java code using Eclipse IDE with watch variables, expression and Inspect.

Step1: Enable breakpoint

Set the breakpoint at the line of code or point of method entry from where you would like to start debugging the code. Right click on the left margin of the editor next to the line of code and a context menu pops up. Select toggle breakpoint in the context menu as shown below:

Figure1: Toggle Breakpoint



Step2: Configure the breakpoint to stop execution

To start debugging, the execution should stop at the breakpoint specified. For this click on breakpoint properties (refer Figure1)  and do the following:

  1. Check Hit count
  2. Specify value as 1
  3. Select “Suspend thread” option

This will stop the execution when the program hits the breakpoint.



Step3: Switch to debug perspective

In Eclipse, select Window –>Open Perspective –> Debug as shown below:

Step4 switch to debug perspective


Step4: Run in debug mode

Now run the program in debug mode. Select Run –> Debug

Step5 Run in debug mode

Now the program starts running in debug mode and you would see the state of the thread as “running”

Step6 running thread

When the program hits the breakpoint the state of the thread changes from “running” to “suspended

Step7 suspend thread


Step5: Debugging the code with Expressions \Watch variables \ Inspect

Now the code stops at the breakpoint. You could use the watch variables / expression to monitor the current value of the debug variable.

Suppose you set the breakpoint at the variable named “counter” and the program stopped at counter variable as shown below:

step8 stops at code\

Add the expression with the variable name “counter” which allows you to monitor the value of the variable as you execute the program:

Step11 watch variableexpressions

You could also right click on the counter variable and select “Inspect” from the context menu

Step12 right click to inspectstepinto

If it is a method then, select the method name and click on “Step Into Selection“. This will allow you to monitor or debug the method execution line by line.


Step6: Use F6 key to step into the method

To “step into” the next executable line of code in the current method, press the “F6 Key”. This will pass the program control from the current line to the next executable line of code.

Step9 Press F6 key


This is a very common issue that most users face after installation of GIT.

Extensive troubleshooting of this GIT issue “Git – Permission denied (publickey)” can be done with the below command:

ssh -vT

Step 7:  Click on Add SSH key, paste the key copied to the clipboard (in Step 3) and store the key




If you have several suites to be run, you could run them in parallel at the same time in different threads.

Parallel suites

In command line the ant task suiteThreadPoolSize can be used to run several suites in parallel using org.testng.TestNG as shown below:

java org.testng.TestNG -suiteThreadPoolSize 3 testng1.xml testng2.xml testng3.xml

This command runs the three suites in 3 different threads in parallel

Parallel methods, tests, classes

In testng.xml file, using the attribute parallel inside the suite tag instructs TestNG to runs tests in parallel in different threads. The attribute parallel accepts certain values as outlined below:

<suite name="mysuite" parallel="methods" thread-count="5">
<suite name="mysuite" parallel="tests" thread-count="5">
<suite name="mysuite" parallel="classes" thread-count="5">
<suite name="mysuite" parallel="instances" thread-count="5">

1. parallel=”methods”: TestNG will run all the test methods in parallel in different threads. The dependent methods will also run in different threads but would respect the order that was specified.
2. parallel=”tests”: TestNG will run all the methods in the same test in the same thread but each test will be run in separate threads. This allows to group the thread-safe classes in the same test so that they will run in the same thread while taking advantage of TestNG’s capability to run tests in several threads.
3. parallel=”classes”: TestNG will run all the test methods in the same class in the same thread and each class will be run in separate thread.
4. parallel=”instances”: TestNG will run all the test methods in the same instance in the same thread and each instance will be run in separate threads.

Also, the attribute threadPoolSize of the @Test annotation could be used to run tests in parallel as shown below.

@Test(threadPoolSize=5, invocation-count=10, timeout=10000)
public void testMethod()

This will invoke the method testMethod 10 times in 5 different threads. The timeout of 10 seconds ensures that the thread is not blocked for more than 10 seconds. The timout applies for both parallel and non-parallel mode.

TestNG allows to perform groupings of test methods. The methods can be declared to belong to groups and TestNG can be invoked to include/exclude certain set of groups. This provides maximum flexibility to structure the tests in a more intuitive way.

Step1: Declare groups in java class

Suppose we would like to group the test methods into two categories functional and sanity. We declare the methods to belong to either of the two groups using the “groups” attribute of @Test annotation.

public class Test1
  public void testMethod1(){
  public void testMethod2(){
  public void testMethod3(){


Step2: Specify groups in TestNG.xml file

Suppose we would like to run the sanity tests alone. We specify the groups in the TestNG.xml file using the <groups> tag inside the <suite> or <test> tag as shown below:

<suite name="mySuite" verbose="1">
  <test name="Regression">
        <include name="sanity"/>
      <class name="sample.Test1"/>

TestNG is a testing framework designed to simplify the testing needs.


Quick overview of TestNG.xml file

  • A suite is an xml file represented by <suite> tag. The TestNG suite can contain one or more TestNG tests
  • A test is represented by the <test> tag. A TestNG test can contain one or more TestNG classes
  • A class is a java class having TestNG annotations. It is represented by the <class> tag. A TestNG class can contain one or more TestNG methods
  • A method is method configured with @Test annotation


Sample TestNG.xml file



Also, it is possible to use packages instead of classes in TestNG.xml file. For this package tag is used as shown below:
