Tech Groups and Events: Connect Over Technology with Meetup

**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** *Tensors, Tokens & Too Much VRAM: A Developer's Guide to Running LLMs Locally* What actually happens when you send a prompt to an LLM? What are tokens, tensors, attention, quantization, and all those mysterious gigabytes of VRAM doing? And why does your GPU suddenly become the most important piece of hardware in the room? This talk takes a developer-friendly tour through the fundamentals of modern LLMs. We’ll try to demystify concepts like context windows, model quantization, and inference performance without requiring a PhD in linear algebra. Then we'll take those concepts out of the textbook and into the real world, looking at tools such as Ollama, LM Studio, and vLLM and what it takes to run useful models on your own hardware. By the end, you'll have a mental model for what an LLM is actually doing, how local inference works, and why sometimes the answer to "How much VRAM do I need?" is apparently "all of it." **YouTube Link** TBD

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!

New models, new tools, new frameworks—and a growing list of things you feel like you should already know. Keeping up with AI can feel like a full-time job. Join Columbus AI Engineering for a practical discussion about deciding what deserves your attention and turning that learning into useful skills. We’ll cover: * **Building T-shaped knowledge:** Develop enough breadth to understand the AI landscape, then go deep in one area where you can build real expertise. * **What to learn:** Prioritize foundational concepts and skills that remain useful as tools change. * **What to try:** Evaluate new models and tools through small, focused experiments connected to problems you actually have. * **What to ignore:** Filter out hype, distractions, and developments that aren’t relevant to your goals. * **Making it sustainable:** Build a manageable routine for finding useful information, practicing, and sharing what you learn. Whether you’re getting started with AI or already building with it, this session will help you make more deliberate choices about where to spend your time. Bring your favorite learning resources—and something you’re trying to figure out whether to learn, try, or ignore.

While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.

**[VS Code Documentary] Watch Party** **[https://luma.com/vscodecommunity](https://luma.com/vscodecommunity)** Erich Gamma once called VS Code an overnight success 10 years in the making. Those 10 years were pretty eventful. Before becoming one of the most widely used developer tools in the world, VS Code started with a small team building online developer tools out of Zurich, called itself Monaco, then Visual Studio Online Monaco, then Ticino (because why not?), became a desktop editor, went open source, became an ecosystem in its own right, went back to the browser, and helped establish a whole bunch of open protocols along the way. And just when it felt like the hard part was done, AI happened. This is the story of how VS Code got here, told by the people who built it and the developers who helped shape it. And now, how it's adapting once again as AI changes what a code editor can be. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

Session Abstract ### Applying Forensic Accounting Techniques using SQL and Python Forensic accountants and fraud examiners use a range of techniques to uncover fraudulent journal entries and illegal activities. As data professionals, most of us will never unravel a Bernie Madoff scheme, but we can apply these same techniques in our own environments to uncover dirty data. This session will use a combination of SQL Server and Python to apply these fraud detection techniques, which include Benford's Law, outlier analysis, time series analysis, and cohort analysis. \*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.

**Welcome to Startup Oasis** If you are a startup founder, developer, UX designer, marketer, or anyone else in the tech ecosystem looking to start, join, or help a tech startup, this event is for you! Startup founders pitch their business or idea to the audience like on Shark Tank. Except there are no winners, and founders are not pitching for money. Instead, founders get their own breakout room to continue building, workshopping, and/or onboarding the startup with attendees. Stay inside the Startup Oasis by joining the [newsletter](https://mailchi.mp/startupoasis/meetup). This is a brand-new type of structure that has never existed before, and there is so much direct value for all parties. Startup Oasis was created to pierce the illusion of accessibility of startups and tech by creating a grassroots forum for early-stage founders to pitch to those in the tech ecosystem to get real-time feedback for their idea or business. See our [overview video ](https://youtu.be/VH11MFd3X1Q?si=eavhvdVj5oSn5RI8)for more info! **Agenda:** 1. **Introductions:** during the first 10 minutes, we will give you the history, structure, and future plans of Startup Oasis and open signups for founders that want to pitch their startups. 2. **Pitches:** each founder will then get up to 3 minutes to pitch their startup. This format is recommended: name, business, the problem, your solution, target customer base, and your biggest challenge/current need. This part is similar to Shark Tank. 3. **Breakouts:** for the remainder of the event, each founder gets a breakout room, and you can talk to the founders in greater detail their about their needs and challenges in a small group setting. This part is similar to a hackathon. Use this [link](https://lnk.bio/startup.oasis) to: * Follow us on LinkedIn * Join our community on Discord * Donate to our cause * Visit our website **FAQ:** **Is this event free to attend?** Yes - Startup Oasis will always be free for anyone to attend. If you would like to donate, you can do so directly on our [website](https://donate.stripe.com/eVa2a0dV27Nlb2ofYY). You can also talk to us about volunteer or sponsorship opportunities. **How do I sign up to pitch?** RSVP here. Right when the event starts, fill out the form and then raise your hand on Zoom. That will also determine the order. You can also buy a VIP ticket to support our cause and guarantee you a spot to pitch. To be eligible to pitch, you must be the cofounder of a technology-based startup. Agencies, consultants, coaches, MLM schemes, and nonprofits are not eligible to pitch, but you can still watch the pitches and join the breakouts. **What happens after the pitches?** The breakout groups open for the remainder of the event. Each founder gets a breakout room, and you can talk more about their business and needs with them. **Can I invite other people that I know?** Yes - please have them RSVP here or on the [LinkedIn](https://www.linkedin.com/company/startup-oasis-global) event listing. **How do I get the most out of this event?** * Founders - In this event, no money is awarded nor are any winners named. We are not here to critique your pitch, just to help you find teammates, cofounders, and feedback from other professionals. Make sure your pitch is 3 minutes or less and clear about what your biggest needs are. * Attendees - If you are new to startups and tech, feel free to just watch with no pressure to participate. If you are looking to join a startup or find a side project, make sure you take notes during the pitches to join the group of the founder that you're most interested in helping. Most founders need help with either developing the product or with a go-to-market strategy. **Do we meet in person?** We do this event in Atlanta, USA each month. We will visit your city in the future to do this event in person during our world tour. If you'd like to help us organize, please let us know! **Content:** We are looking for founders to be interviewed or people to interview founders for short videos. Let us know if you are interested!

Missed Level Zero 2026 — or want to relive the best of it? Last year, sixty-six speakers delivered over a hundred hours of can't-miss OT cybersecurity programming. In this symposium, you'll hear it straight from the contributors and top-rated speakers who made it happen: the lessons learned, the ideas planted, and the moments that mattered most. Across a four hours of panel discussions, we're bringing back the voices that defined last year's conference to reflect on where ICS/OT security stands today — what's changed, what's stuck, and what the community is still wrestling with. And we're not just looking back. Throughout the day, we'll drop clues about what's coming in 2027 — a bigger, bolder Level Zero built on your demand for more. Think five full days of content, including two brand-new pre-conference days ahead of the three-day main event. Whether you were there in person, watched from afar, or are just discovering Level Zero for the first time, this is your chance to catch up on the conversations that mattered — and get a first look at what's next. **[Join us for Visions and Reflections.
