Fearless concurrency with cats-effect IO
Build rock-solid concurrent apps in Scala without the headaches. In this hands-on workshop, you'll master cats-effect IO, from structured concurrency to blocking vs. non-blocking IO, and leave ready to crush any concurrency challenge with confidence.

Implement a Functional Language in Scala
Build a tiny functional language in Scala! In this workshop, you'll implement a simplified version of Dhall from scratch, learning about syntax, type-checking, and evaluation through hands-on coding and interactive exercises.

Orchestrating AI Coding Assistants with Actor-Based Specifications
Discover how actor-based system modeling turns unclear business needs into structured specs that AI assistants can implement consistently. This workshop teaches a specs-first approach with specialized AI agents, giving you architectural control while accelerating development.

Crafting Elegant DSLs in Kotlin
Type safe builders, or DSLs (Domain-Specific Languages), allow us to describe complex logic in a readable and elegant way. Kotlin is an excellent language for building DSLs, offering features specifically designed with DSL construction in mind. This workshop explores the key techniques required to build such DSLs, and together we'll create a production-worthy example.

Solid Code with Liquid Types!
Are you tired of writing tests only to see production crash at 5:00pm on a Friday? Traditional type systems can save you from adding an integer to a string but can they save you from being fired? We intoduce Liquid Haskell (don't worry, no previous Haskell knowledge is required) a tool to definitively prove that your code does what you want, no tests needed!

Pure Functions, Powerful Effects
Effects (systems) help us understand the behavior of our functions, and document those in the signatures. Kotlin provides several facilities that make it possible to track effects in the language in an idiomatic way. This workshop explores those techniques, and how they are reflected in popular libraries in the Kotlin ecosystem.

KDB-X: Experience the Fastest Time-Series Database for Free
KDB+ is the world's fastest time-series database, now freely available for non-commercial use with KDB-X, PyKX, and KDB.AI. This workshop shows how to express powerful analytics with q, connect Python workflows with PyKX, and add real-time intelligence with KDB.AI through live examples.

Match the BEA(M)T: Real-Time Generative Music with Elixir
What if pattern matching could make music? In this hands-on workshop, we'll build a real-time generative music system in Elixir, where pure functions shape melodies, concurrent processes run virtual instruments, and supervisors keep the groove alive, even after crashes. Using the BEAM as our conductor and an external audio engine, we'll turn code into sound and end with a one-of-a-kind live performance.

Which [X] Are You? Vector Similarity in Rust with Axum and SurrealDB
Build a "Which [X] are you?" quiz application using pure geometric vector matching. Users answer three 1-5 Likert scale questions, creating a coordinate in 3D space. We'll store potential outcomes as vectors in SurrealDB and use vector similarity search to find the best match. Through this hands-on workshop using Axum and simple HTML, you'll learn practical Rust web development while demystifying how vector search actually works - just distance calculations, no ML required.
