Esri/Geoloqi/Foursquare Hackathon Recap from San Francisco!
Geoloqi/Esri had a great time at the Foursquare Hackathon this weekend! Not only did tons of people show up to hack (over 200 globally, 100 at the NYC office, and around 50 at the SF office), we got to hang out with our friends Jim Young and Bronwyn Agrios from Esri’s SF office!
Together we built interesting stuff, saw interesting hacks, and met lots of new people.

We awarded an iPad prize to Leah Vaughan (second from left) for her great use of an Esri map! Her app was called “Stuck at the Airport”. It recommends interesting places/things to see around you when you’re in transit areas (train satins, airports, rest stops, etc.).
Also, Kyle Drake, Aaron Parecki and I put together a hack using the NASDAQ and Foursquare APIs called NASDAQ Facts (below).
NASDAQ Facts for Foursquare tells you the stock price of every public company you check into. Stock markets are about more than numbers. Discover which places on Foursquare you visit are public companies, get information on how they are doing, and learn more about them by clicking on a link. The information automatically appears on your Foursquare app after checking into a place! (We ended up winning a flying shark for this hack!).

We finished our hacking early, so Kyle Drake hung out in the Foursquare office hammock.
See you next time!
You can see a list of all the Foursquare Hackathon projects here, as well as the local winners and global winners! If you’d like to build cool stuff with us in the future, let us know! Who knows? We may soon be coming to a hack day near you!

Like PacMan for heritage trees! You go around town finding trees and collecting points. You get bonus points for collecting all trees in a neighborhood. You receive your score via an SMS from Tropo. When you’re near a tree, you can call Tropo and it will quiz you to identify it, getting you even more points! It was this clever use of the voice recognition capabilities of Tropo that made this application stand out.
“Don’t Eat That!” pulls health inspections from the county web page. If you use Geoloqi, you can subscribe to notifications of scores under a certain threshold for restaurants within 100 meters of your current location. You’ll get an SMS that says “What ho! You might not want to eat at Backspace, their last inspection score was 93!” That way you can gawk at dirty restaurants near you! This app will also post links to the reports as tips on Foursquare!
Honorable Mention. Finds all the bars in the business license dataset and matches them to Twitter feeds by searching Twitter lists. The map shows notification icons on the map and shows the latest tweets from every bar. A future mobile version could use the Geoloqi API to track your location and receive Geonotes for specials at bars near you.
Honorable Mention. Finds pets available for adoption from the Multnomah County Animal Services database and petfinder.com. You can read the descriptions of the animals and send out a tweet for them. Using the Tropo API, the non-technical foster homes can call in and ask for a short update about the pet, so the shelters aren’t required to know how to use Twitter. On “Woof Wednesday” the dogs that are looking for homes will tweet their latest updates or a random pet.
