What is jq? I use jq when I need a quick way to gain insights on JSON in the command line. According to the jq manual, “a jq program is a “filter”: it takes an input, and produces an output.” This post will provide examples of how jq can help you answer questions about JSON. I recommend installing jq and trying out the examples below in your terminal. I’m going to use the Google Books API to query a list of quilting books.

Message brokers, like RabbitMQ, accept and forward messages between separate applications. Messaging is useful for decoupling applications. This means that different applications are connected through a message broker, but they don’t directly rely on one another.

Publish/Subscribe architecture pattern The publish-subscribe (pub/sub) pattern is a messaging pattern where senders of messages (publishers) do not program the messages to be sent directly to specific receivers (subscribers).
I’ve written a bit about Filth Finder, an app that surfaces health inspections from NYC restaurants near you. Most recently, I wrote about the API that served the restaurants to the frontend. While this implementation worked, it was pretty slow to load. In an effort to speed up the loading time, I rewrote the backend to pull the of index restaurants from Google Cloud Storage. Check out how much faster it loads.
Filth Finder is an application that loads NYC restaurants near you and allows you to view health inspection violations at each restaurant. One problem that had to be solved when developing Filth Finder was how to calculate the distance between the user and all of the amazing restaurants NYC has to offer. The NYC Open Data API provided the addresses for each restaurant, but Filth Finder needed the geolocation of those restaurants.
If you are going to LTV Conf and want to chat about tech, please say hi. I received a scholarship to attend LTV Conf, and I’m looking forward to attending next month. The conference brings together leaders from the SaaS industry to share ideas about marketing, scaling, tech and entrepreneurship. I found out about the scholarship through Diversify Tech’s newsletter, and I applied knowing that it would be a cool opportunity to learn more about the SaaS industry.
Have you ever walked around NYC looking for a place to eat? Have you ever wished there was a way to find the health inspection info for restaurants near you? Well, now you can do that using Filth Finder, a React app with a Rails backend. This application fetches data from the NYC Open Data API. I recently took the opportunity to rewrite one of the components using React Hooks!
