Everyone, please join us on Monday, June 22 at 7 p.m. to discuss [Discipline And Punish](https://www.amazon.com/Discipline-Punish-Prison-Michel-Foucault-ebook/dp/B007OLYO7I/ref=tmm_kin_swatch_0) by [Michel Foucault](https://en.wikipedia.org/wiki/Michel_Foucault)\. \| 309pp\. ***Discipline and Punish*** is an analysis of the social and theoretical mechanisms behind the changes that occurred in modern Western penal systems. Foucault argues that prison did not become the principal form of punishment just because of the humanitarian concerns of reformists. He traces the cultural shifts that led to the predominance of prison via discourse on the body and power and by examining the parallel use of discipline in schools, hospitals, and the military. A long list of other books we are considering reading is available [here](https://docs.google.com/document/d/1coctalgTkYrjCFUtZniKSksN6wvALCjH7NvR7M02rMA/edit?usp=sharing). Our meetings have a $3 fee, purely to offset the cost of Meetup. This can be paid via Venmo, Paypal, or in cash. We do not accept requests from authors to read their books. We will never ask for money beyond the above fee. If you receive offers purporting to come from the club they are part of an online scam.

Title: Quantum Computing for Business (Exploring Opportunities Available Today) Date: June 27 2026 Saturday Noon - 14:00 EDT Summary: Big media reports that current quantum computers are not able to attack business problems at scale. In Ron's experience, this is only about 95% true. He has found that certain types of quantum computers, specifically quantum annealers, are very good at solving constraint based optimization problems at business scale. This presentation will answer the question “What is quantum computing?” by comparing quantum computers to classical computers and describing the various types of quantum qubits. Ron 'll introduce what quantum computers can be used for and what they shouldn't be used for. Next, Ron will look at a number of quantum computing use cases that are currently available to businesses today. Finally, Ron ’ll present conclusions with a brief discussion of future hardware. There will be time for Q & A. Speaker: Ron has been fortunate to have worked in a broad range of technical disciplines during his career. Areas in which he developed expertise and innovative results include, digital hardware design, silicon functional architecture (chips), computer language compiler development, and medical software. Ron has recently immersed himself in quantum computing technologies and has obtained more than a dozen certificates across the quantum spectrum. These technologies include various hardware platforms, numerous quantum programming frameworks and quantum sensors. As a co-founder and CQTO of B2Quantum, Inc, Ron has served as a quantum computing Subject Matter Expert (SME) for a large pharma company. As a SME, he performed quantum computing use case analysis, strategic planning, budget guidance and risk analysis. Outside of the technical arena, Ron is a licensed pilot, certified open water SCUBA diver, bicyclist, wood worker and a once in a while artist.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. 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.
