We are excited to announce our upcoming Spring Community Showcase. This event is an opportunity for individuals at all skill levels to come together and share their experiences with Rust. Whether you’re working on a personal project, contributing to an open-source initiative, or teaching a concept related to Rust, we invite you to present your work and insights. Take this opportunity to build your confidence and share what you are doing. Speakers === If you would like to give a presentation, please send Ernest a direct message with your talk title and a brief abstract of approximately 60 words. Each presentation will last about 25 minutes, followed by 5 minutes for questions and answers, for a total of 30 minutes. We have four slots available this month. **Dan Groshev** Okmain Library: You have an image, but you want a colour How do you pick a colour that represents an image but also looks good? Dan will talk about his Okmain library, colour science, auto-vectorisation, SIMD, and his experience building it in Rust and PyO3. **Jérôme Étévé** Mockapot: A percolator library in Rust Jérôme is the author of the Mokcaccino library, which started as a way to marry my interests for Rust and for search technology. He will discuss the design, the tricky aspects of Rust he learned along the way, and how Rust and Python complement each other. **Evadne Wu** JavaScript Sandboxing using Deno on top of Elixir & Erlang/OTP. Intelligent AI agents can write code that calls existing APIs in secure sandboxes, allowing higher token efficiency, better performance, and lower per-turn latency. Deno’s primitives in Rust can be integrated into such an agent harness, utilising the Elixir programming language and the Erlang/OTP runtime, which allows you to construct agentic systems that are massively concurrent and fault-tolerant.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
