(Spring) Booting Java to accept digital payments with USDC
Posted on June 16, 2023, Level intermediate Resource Length medium

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.

Posted on June 9, 2023, Level intermediate Resource Length medium
Long before Python 3, and ChatGPT, and TikTok, poor developers had to write their web servers using *shudders* Python 2 native features. This meant no asynchronous operations. 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.
