Connecting My LangGraph AI Agent to Postgres

A stateful LangGraph agent was developed to streamline a 15-minute booking process, mimicking a customer service representative. It features a user-friendly Streamlit UI and a backend powered by a Postgres database. The agent can respond to customer queries, calculate service prices, manage acceptance or rejection of services, propose appointment time slots, and confirm booking details. The agent operates in two persistence modes: in-memory for quick testing and Postgres for durability. Testing can be conducted locally with Streamlit or using Docker to simulate a production environment. Docker allows the application to interact with a PostgreSQL server without local installation, enhancing reproducibility. The project includes a docker-compose.yml file to initiate a PostgreSQL container, and users can also utilize a cloud-based Postgres solution. The application behavior remains consistent regardless of the database setup. The complete source code is available on GitHub for testing and further enhancements.

Connecting My LangGraph AI Agent to Postgres

A stateful LangGraph agent was developed to streamline a 15-minute booking process, featuring a user-friendly Streamlit UI and a backend powered by a Postgres database. The agent responds to customer queries, calculates service pricing, manages service acceptance, suggests time slots, and confirms appointment details. It operates in two modes: in-memory for rapid testing and Postgres for persistent storage. Testing can be done locally using Docker, which simulates a Postgres environment, or with a hosted Postgres instance. The project includes a docker-compose.yml file to initiate a PostgreSQL 16 container, allowing the application to connect to the database. Data persistence is ensured through Docker volumes, and the application can be run with specific commands after setting up the environment variables. The system has been tested successfully, demonstrating its ability to manage bookings and maintain data integrity across sessions. Future enhancements are planned to improve the booking workflow and integrate additional communication channels.

Clown of Slipknot states that “AI is part of life” and talks about his passion for Minecraft

M. Shawn “Clown” Crahan, the percussionist and creative director for Slipknot, has launched a custom ‘Minecraft’ server called ‘Vernearth’, which he describes as a significant artistic endeavor reflecting his lifelong passion for video games. His gaming journey began with early consoles like Atari and Intellivision, and he views ‘Vernearth’ as a culmination of his creative exploration, influenced by various games including ‘Quake’, ‘Goat Simulator’, and ‘World of Warcraft’. Crahan has a personal connection to ‘Minecraft’, having introduced it to his children and used it as a means of coping with grief. He also shared his perspective on artificial intelligence, likening it to a personal assistant and suggesting its potential for enhancing creativity in music. Crahan believes that younger generations will embrace AI technology, contrasting their views with those of older generations who may be more apprehensive about its implications.

URI art professor’s work featured in ‘Minecraft’video game

Travess Smalley, an assistant print media professor at the University of Rhode Island, discovered Minecraft over a decade ago and began exploring its creative potential. He has integrated his artistic expressions into the game, which has sold over 350 million copies globally. Smalley uses a "chance flower" program to generate unique art, similar to the procedurally generated worlds in Minecraft. During the COVID-19 pandemic, he developed work on a dedicated Minecraft server, creating a digital world that transforms the game into an expansive poem. His projects include "pixel rugs," generative digital artworks translated into hand-woven rugs, and "CRAWL," a video maze game featuring 512 distinct artworks. Smalley plans to release a book titled "Pixel Rugs" in January 2026 and encourages his students to use Minecraft as a medium for artistic expression.
