While we’re all still recovering from our Thanksgiving-induced food comas, we wanted to share some of our upcoming events for December! This Thursday, some of our engineers will be giving lightning talks at the Women Who Code meetup so make sure to come! We’re also very excited to be sponsoring the Women Who Code Holiday Party in Waterloo Ontario on December 11th. If you’re in the area, RSVP and stop by! For the rest of the week (through December 5th), Yelp will also be matching donations to Women Who Code (up to $5,000 total). Please consider donating and helping them...

We recently held the 15th edition of Hackathon, a two-day event comprising of pure, unadulterated hacking, innovation, creativity and fun. Folks clustered together, hammering on their keyboards, scribbling on whiteboards, and some electrical engineers were plugging away on their breadboards. The kitchens were filled with delicious catered food, and fresh fruits and snacks lined up in the common spaces. We even had a school of remote-controlled sharks lurking around the office and taking over the meeting rooms. Those ominous-looking RC sharks do not seem to deter our intrepid hackers! Close to 60 great projects came out of the event from...

Yelp uses Elasticsearch to rapidly prototype and launch new search applications, and moving quickly at our scale raises challenges. In particular, we often encounter difficulty making changes to query logic without impacting users, as well as finding client library bugs, problems with multi-tenancy, and general reliability issues. As the number of engineers at Yelp writing new Elasticsearch queries grew, our Search Infrastructure team was having difficulty supporting the multitude of ways engineers were finding to send queries to our Elasticsearch clusters. The infrastructure we designed for a single team to communicate with a single cluster did not scale to tens...

As you probably heard, Yelp attended Grace Hopper this year. Nine software engineers from different teams attended and, for many of us, it was our first time. It was a unique experience to see so many talented women in one place. In addition to the talks and panel discussions, we also had the opportunity and pleasure to represent Yelp at the career fair. It was amazing to see a consistent flow of students and industry talent, all happy customers, stop by our booth to speak with us and tell us their stories of using Yelp. We had such a great...

At LAUNCH Scale last week, I gave a talk to over 75 co-founders (CEOs and CTOs) on how we’ve scaled traffic here at Yelp. It brought back memories of Darwin biting through our ethernet cable and reminded me of the run up to our IPO, making sure we had enough capacity to handle the expected surge in traffic from the world’s press (and more recently, the launch of Yelp in Hong Kong!). For close to 8 years, I’ve had the privilege to work alongside some of the best engineers in the world and have seen the meticulous work and thought...
