Join Sandon Jacobs on Monday, May 25th from 6:00pm hosted by Improving! 📍**Venue:** **Improving Office** 171 East Liberty St Unit 235 Toronto, Ontario M6K 3P6 **Directions (171 E Liberty St - Suite 235)** **By transit** Streetcars 504 and 509 both travel close to the office (less than 10 minute walk to the office from either), the lakeshore GO train is also a 5 minute walk from the office. **By car/parking** On street parking is available - there are a handful of paid parking spots directly in front of the entrance - with a large city parking lot across the street. **Entrance** The entrance to the office is beside the Bulk Barn entrance facing Hannah Street. There is an Improving logo on the door. 🗓 **Agenda:** * 6:00pm – 6:30pm: Welcome, Food/Drinks & Networking * 6:30pm - 7:30 pm: **From Chaos to Contract: Governing Data Streams** by Sandon Jacobs **💡 Speaker Details:** Sandon Jacobs, Senior Developer Advocate, Confluent **From Chaos to Contract: Governing Data Streams** So you’re committed to this path of data streaming with Apache Kafka. But, here’s a question: would you build a REST API and make users guess the request and response formats? Doing so opens a Pandora’s Box… * What’s the domain model? * Name the operation… POST? GET? PUT? PATCH? * What does this error code even mean? * Is the documentation - if it even exists - accurate and relevant? * Imagine the complex, repetitive logic every consuming system would need to implement to make sense of it all. In a distributed, asynchronous system, these problems are magnified. Apache Kafka's flexibility—messages as simple bytes—is a huge strength, but it's also a major risk. While your event streams likely consist of some structured data (maybe JSON strings), enforcing structure, managing evolution, and basic validations aren’t a hard requirement. This leaves consumer applications to perform this preprocessing of every event - even if that event has no business value. In this session, we'll define data contracts and how to enforce them at the source - the applications that produce events. We’ll cover the practice of using a schema registry - supporting popular serialization formats like Apache Avro and Google Protobuf - to design events in the terminology of our business domain. Because data structures change over time, let’s discuss safe schema evolution practices. Then we’ll utilize these contracts with schema registry-aware producer and consumer code. We’ll end our time by looking at how smart CI/CD pipelines and build-time checks can add an extra layer of defense against the costly problem of poison data. It’s time to stop guessing and start governing. Join us to learn how to move validation upstream and transform your event streams into high-quality, discoverable data products. You’ll walk away with a practical blueprint for enforcing schema integrity and automating evolution—ensuring your data streams are a trusted asset. \*\*\* DISCLAIMER We don't cater to attendees under the age of 18.

Can your agents scale without bankrupting your API quota or your compute budget? Join this session to explore a production-ready architecture that uses the LLM Council pattern, Google’s Agent Development Kit (ADK) for Java and Spring AI, all deployed on Cloud Run. And discover how replacing probabilistic reason-and-act (ReAct) loops with LLM Council enable goal-oriented action planning (GOAP) creates agents that are not only smarter but also significantly lighter and faster – making them the perfect workload for serverless execution. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu. Please consider helping to support the venue by planning to have supper during the talk. **Speaker Bio** Dan Dobrin is an App Architect in Google Cloud, helping customer teams adopt modern AI technologies, cloud-native patterns, practices and technologies in GCP.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

We are bringing Microsoft Build sessions to Columbus Ohio! The Central Ohio Azure Meetup and Central Ohio .NET Developer's Group (CONDG) are coming together to bring some of the labs and breakouts from Microsoft Build to your backyard.

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
