Jeff Linwood, a software developer with Biscotti Labs, loves dogs. He and his wife even adopted one from the Austin Pets Alive shelter.
But helping one dog wasn’t enough, he said.
He wanted to do more, but he couldn’t adopt any more dogs. That’s where he got the idea for a mobile phone app to help match dogs with potential owners.
He signed up for the PayPal Battle Hack competition, held last weekend at TechShop in Round Rock, and he spent Saturday and Sunday working on the project.
It paid off.
On Sunday night, PayPal announced PayPup, Linwood’s app, won Battle Hack. The mobile phone app lists all dogs available for adoption from Austin Pets Alive along with a donation button for each dog to help pay for medical expenses.
Linwood, who also works as an adjunct professor in journalism at the University of Texas, received a laser-etched glass trophy and an 4.3 pound 21-inch solid steel axe trophy.
PayPal will fly him and nine other city winners to the world finals in San Jose in November for one last hack-off where one team will receive a $100,000 grand prize.
So far, PayPal has had competitions in New York, Miami, Seattle and now Austin in the U.S., said Jonathan LeBlanc, developer evangelist at PayPal. It has held international Battle Hack competitions in Tel Aviv, Moscow and Berlin. It still plans Battle Hacks in Washington, DC., London and Barcelona.
“We chose Austin for its innovative culture,” LeBlanc said. “The city is known as a place that is changing the technology industry and creating start ups.”
More than 150 people signed up for the Battle Hack. At TechShop, the hackers had access to laser machines, 3-D printers and all kinds of software and hardware throughout the weekend.
They also had plenty of food and many teams stayed up for days on end.
Tap to Pay, a hardware hack that turns a Raspberry Pi, a credit-card sized computer that plugs into a keyboard, and mobile phone into a mobile payment system, received second place. Lana Jones and Alejandro Vidal created Tap to Pay. They met at the event and worked until 4 a.m. Sunday morning to finish their hack.
“It allows for small transactions on the fly,” Jones said. A kid can use one at the lemonade stand to take payments from customers, she said.
Jones programmed a Raspberry Pi to communicate with a mobile phone to allow for payments anywhere with a simple tap of the phone on the device. It only costs $35.
Trust in Dragons, a crowdfunding platform for non-government organizations that ensures transparency and accountability with gamifaction features, received third place.
The focus of the Battle Hack competitions is to reconnect with PayPal’s developer community, said LeBlanc with PayPal.The company’s developer tools and API were focused primarily on web transactions until recently when the company began to focus more on mobile payments.
“What we are seeing with the Battle Hack competitions is a complete culture shift at PayPal,” LeBlanc said. “PayPal’s President David Marcus has made it clear that our goal is to fix and make better our infrastructure for the developer community.”
The sponsors of the event included Twilio, SendGrind, Microsoft and Nokia. They also gave out sponsor prizes to the teams.

  2. Hello to every one, because I am truly keen of reading this webpage’s post to be
    updated daily. It contains fastidious stuff.

  3. Woah! I’m really enjoying the template/theme of this blog.
    It’s simple, yet effective. A lot of times it’s very difficult to get that
    “perfect balance” between user friendliness and
    appearance. I must say you have done a amazing job with this.

    In addition, the blog loads super quick for me on Internet explorer.
    Exceptional Blog!

  4. I did this with my personal cell phone, which ‘ unlike my
    work Blackberry ‘ had no password on it. ” I do not believe “true love” can exist indefinitely without both components. It’s very easy to fall deeply in love with a woman with these “magical” skills.
