**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9

Join us for an engaging panel discussion on **AI Agentic Coding** and how autonomous AI systems are transforming the way software is built. Experts in AI, software engineering, and developer tools will share insights on how agentic AI—systems that can plan, reason, and execute coding tasks—is reshaping modern development workflows. The discussion will cover topics such as AI-assisted development, productivity gains, challenges around reliability and governance, and what the future of software engineering may look like with AI agents as collaborators. Whether you’re a developer, tech leader, or AI enthusiast, this session is a great opportunity to learn, ask questions, and explore how agentic AI is redefining coding

The aim of this group is to get together and practice our German. Doesn’t matter if are a beginner or a native speaker. The goal is to speak and improve our German. Everyone is welcome! If the weather is good, look for us in the Biergarten. Pro Tip: Get there before 6:00 for happy hour pricing.

Hey Everyone! Let's meet at Belle's Bread Bakery and Cafe. There is lots of free parking and easy access to the cafe and many shops and restaurants as well.

Looking forward to seeing you soon.

**We'll hike 3.4 miles on the Killdeer and Yellowlegs Trails - both out and back gravel trails. If we want more mileage we can repeat an out and back. Pace of around 3.5 mph, no one left behind and those who want to go faster sure can!** **As always optional lunch after.** **This is the second Metro Park in the lineup - with 21 to go (plus more are being added).** **Also I have a conflict and am not available so have asked Karin to lead!**

Short North Street Skates return Saturday, April 4 and we’re excited to get back rolling together. These weekly rollouts are a chance to move through the city as a group, build community, and create more visibility for skating and small-wheeled movement in Columbus. Details: Meet: 1160 N High St 9:30 AM meet 10:00 AM rollout All wheels welcome We’ll be skating through the Short North and surrounding areas at a steady, social pace. Routes will use a mix of streets and bike lanes, so comfort navigating the city is helpful, but you don’t need to be an expert. If you’ve been meaning to come out, this is a great place to start. Come solo or bring a friend!

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!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches. * **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason. * **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes. ## Discussion Questions 1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie. 2. **Can good intentions rescue a bad outcome?** 3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome? 4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend? 5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles? 6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way? 7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time? 8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?
