Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

It's not specifically just for me but for my team at the World Largest Trivia Contest [0]. It's a 54 hour long contest, questions are broadcast over the radio, you have the length of 2 songs to call in the answers, and you can use any source to find the answer. Sounds easy, right? Just Google it? Nope. "In a big screen flick, XYZ is talking to ABC about something. In the background, a train passes. What does it say on the train?"

This has led to a ton of fun little coding projects to help us answer questions better. A lot of very hard to Google questions involve album covers, so I ran every album cover I could get through Google Vision and built a little search engine. Another part of the contest is short (1-2s) clips of songs being broadcast and you have a few hours to come up with what they are. We built a massive fingerprint library ahead of time and used it to answer some of those (Google finally got better at this too, before we built this, it'd never work because the clip was so short). We also use AWS to live transcribe the broadcast because one of the hardest parts was remembering "were they asking for the actor? their character? the movie?" and having to wait until they ask the question again between songs.

Next up is a parallel auto-dialer. There's only a handful of people answering phones, so actually calling in the answer can be a struggle.

See if you can answer in about 6 minutes:

What is the name of the first number one single on the billboard hot 100 to include the voice of Bob Dylan?

This question was worth 110 points (points are 2000 / number of teams that answered), so only 18 or 19 teams answered it correctly out of over 300.
