Hey Poetry Lovers! This group is on a roll. Here’s the gist: We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week. For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form). Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.) We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions. Finally, if you plan on sharing a poem, consider how you will do so. Some options include: * Print 5-10 copies to distribute in person * Take and share screenshots in the Discord chat. * Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat. Most importantly, we’re excited to meet you! Catch you on Saturday, Diego / Ian / Cayden / Nate / Otasha / Lia / An

# 🔐 Secure the Vibe: AI-Generated Code, CVEs & OWASP Risks AI-assisted development (“vibe coding”) is changing how we build — but it’s also introducing new vulnerabilities, risky dependencies, and overlooked attack surfaces. If AI writes the code… who reviews the security? Two security professionals will break down the real risks behind AI-generated applications and how to mitigate them before they reach production. *** ## 🧠 What We’ll Cover **1:00 PM – 2:00 PM \| Live Walkthrough & Demo** * Real-time AI code generation * Identifying vulnerabilities in generated output * How CVEs and insecure dependencies propagate * OWASP Top 10 risks in AI-assisted builds * Prompt injection, secret leakage, hallucinated APIs **2:00 PM – 2:30 PM \| Interactive Q&A** * Audience code review discussion * Mitigation strategies * Guardrails for secure AI workflows *** ## 🎯 Who Should Attend * Developers using AI coding tools * DevOps & Cloud engineers * Security professionals * Anyone shipping AI-assisted software AI accelerates delivery. Secure engineering prevents disaster. Let’s make sure we’re doing both. 🥨 Light bites and refreshments provided. Bring a laptop if you’d like to follow along.

We will show a variety of methods for building agents that run in Microsoft Foundry. This covers the different types of agents: Prompt, Multi, and Hosted, as well as the development lifecycle using evals and traces.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
