(Spring) Booting Java to accept digital payments with USDC
Posted on June 16, 2023, Level intermediate Resource Length medium
It's funny how a seemingly meaningless event in one's life can lead to an unexpected change. For me, one of those events happened in July 2021 when my flight home was delayed by so much that I paid for my very first Uber. For this article, I wanted to see how easy it is for a web2 developer to use Java in order to perform some Fintech transactions using web3 and USDC over the Ethereum blockchain. My plan is to use the Circle Java SDK, Java 17, and a Spring Boot 3 RESTful API. By John Vester.

How to upgrade your Flask application using async
Posted on June 9, 2023, Level intermediate Resource Length medium

The frameworks that arose from this era proliferated and became cornerstones of web development. There might even be a synchronous Python web server showing you this text right now. But things change, and with Python 3's native support of asynchronous operations came a new standard - Asynchronous Server Gateway Interface (ASGI). By vidavolta.io.

How to use Azure functions with MongoDB Atlas in Java
Posted on May 15, 2023, Level beginner Resource Length medium
In this article, we are going write the function as a service (FaaS) — i.e., a serverless function that will interact with data via a database, to produce meaningful results. FaaS can also be very useful in A/B testing when you want to quickly release an independent function without going into actual implementation or release. By Mohit Sharma.
