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.

Don't be disappointed if you don't see a bunch of people attending. I advertise this on multiple platforms and the class usually sells out. Improv comedy uses several techniques to create laughter. These include, creating an atmosphere free of judgement, saying 'yes', active listening, being positive, putting your focus on others, and the importance of play and laughter. Not coincidentally, these are the same things that happen to us naturally when we are bonding with another person. In this class, we'll explore these techniques not with the goal of being funny, but with the goal of being people that other people want to be around. The organizer, Ralph MacLeod, is a co-founder of two independent improv clubs in Toronto - Bad Dog Theatre and Social Capital Theatre. He's been teaching improv for over 30 years. He also teaches these same techniques to several organizations including UofT, Google, Kraft, Shopify and many, many more. Please feel free to ask any questions you may have! FAQs and Good To Know.... After every event, a group from this class sit down and have a drink together so be prepared to stay if you want! Of course, you don't HAVE to. You also don't have to be single or bring a friend. The vibe of this class is much more 'making new friends' than a 'singles' mixer'. We usually run to 8:15 so pay for extra parking!

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Main Library, Meeting Room 2B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. 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
