Kotlin Thursdays
Kotlin is a statically-typed language that runs on the JVM. Developed by a small JetBrains team in St. Petersburg, Kotlin is one of the hottest upcoming languages being used around the world. We're here to grow together as an open-source community and to learn collaboratively!
Crowdsourcing Kotlin-focused Tutorials
From content on the Kotlin language itself to programming paradigms to frameworks, we encourage anyone to submit content on anything Kotlin related. Our goal is learn collaboratively, meaning that the Kotlin Thursdays team is ready to help you submit content to share with others.
How do Kotlin Thursdays work?
Every Thursday, we release new content every season. We have blogs available here in KotlinTown. This season, we're creating webisodes to compliment that content. Code and documentation related to content is available on Github.
Interested in contributing? Head over Github to learn how you can get started :)
Happy 10th year, JCertif!

Cassie Shum discusses the architectural evolution of GraphRAG and why data foundations are critical for advanced AI workflows. She explains how traditional vector RAG falls short when addressing global context, multi-hop reasoning, and provenance. She shares enterprise strategies for building semantically structured knowledge graphs that shift raw orchestrating logic down to the data layer.

The library has experienced many updates since its release, and migration from the previous version is necessary.
By Daniel CurtisPresentation: The Infrastructure Challenge Behind Production AI
The panelists explain the realities of running AI systems reliably at scale. While building models is solved, maintaining production databases under constant pressure is not. They discuss the emerging architectural decisions separating teams that scale gracefully from those facing catastrophic outages, and what engineering leaders must rethink today.
By Simerus Mahesh, Alex Infanzon, Meryem Arik, Luca Bianchi, Renato LosioPresentation: Trustworthy Productivity: Securing AI-Accelerated Development
Sriram Madapusi Vasudevan discusses industry-converging patterns for securing autonomous AI agents in production.
