Step into 2026 with intention, clarity, and a creative practice designed to help you see yourself more clearly. In this special Confidence Lab session, we’ll explore confidence as something you can curate - through the choices you make, the qualities you amplify, and the story you choose to step into. We’ll start with a short guided reflection to surface the traits, habits, and energies you want to nurture in the coming year. Then, using collage materials selected specifically for this workshop, you’ll translate those insights into a visual composition that represents the version of yourself you’re ready to grow toward. This isn’t about resolutions or perfection. It’s about crafting a grounded, imaginative vision of your next chapter - one that feels honest, energizing, and fully yours. All materials are provided. Just bring yourself (and a friend) and a willingness to explore what confidence can look like for you in 2026. **Featured Partner: Columbus Collage Collective** The Columbus Collage Collective was started in August of 2023 by Emily Morgan (aka Lovely But Dead) and Douglas Cuckler (aka Wonder Doug) as a place for collage enthusiasts to gather and create art together. The collective has since become a 501(c)(3) non-profit organization with the mission to hold free or low-cost collage events across central Ohio. The CCC welcomes all artists of all backgrounds and skill levels and encourages folks to take this time to step away from everyday existence and create art with people who share a love for this dynamic art form. All materials—magazines, scissors, craft knives, glue, paper, cardboard, and more—are provided, so there's no need to bring anything at all (though you're welcome to bring a friend or a favorite tool if you'd like!). We also encourage folks to take home magazines and materials from our events to support continued creativity!

Whether you’re launching a business, leading a team, navigating change, or simply striving to show up more fully—you belong here. Our work demands clarity, courage, and conviction—but the pace of daily life can erode our sense of self. Confidence Lab creates space to reflect, reconnect, and grow with others doing purpose-driven work. It’s designed for entrepreneurs, nonprofit leaders, creatives, corporate professionals, activists, and anyone ready to lead with authenticity and impact. ***Please note:*** *All are welcome! If cost is a concern, please use promo code PUBLIC to access a free ticket—we want you to join us.*

**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.

**Doing KPIs Right: a KEY to Analytics (and AI!) Impact!** On the one hand, KPIs are such a Business 101 concept that it may seem a little silly to dedicate an entire session to the topic. On the other hand, KPIs get handled so poorly so often that a case could be made that this meetup could just be one of the most impactful sessions of the entire year! We’re starting off the year at a new location: [COhatch Upper Arlington](https://www.cohatch.com/locations/columbus/upper-arlington/) but with a familiar speaker, Tim Wilson! We’ll be back at Rev1 in February, when the speaker will presumably not be Tim. Tim will make the case that effectively measuring performance of projects, campaigns, and initiatives (and even meetups!) should be a foundation for any data analytics program. Topics covered will include: the “two magic questions” of performance measurement, how to help business partners distinguish between outcomes and outputs, and effective tactics for collaboratively establishing KPI targets. He will also stick his neck out by demonstrating some of these techniques in real-time by measuring whether his talk lives up to the promise of this description! All CBUSDAW events are free thanks to our 2026 Sponsors: Clarivoy, Conductrics, What Box Consulting Group, and Piwik PRO. Check out [cbusdaw.com](https://cbusdaw.com) for more information.

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

**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 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA

**Details:** In recent years, the development of scalable continuous optimization solvers on GPUs has made significant progress, primarily driven by advances in GPU-based sparse linear algebra. We first introduce MadNLP.jl, a GPU-native solver for nonlinear programming (NLP) based on interior-point methods and sparse direct solvers. It was the first solver in the suite and remains central to solving general nonlinear problems efficiently. Building on this foundation, MadNCL.jl is a robust meta-solver that orchestrates multiple NLP solves to handle degeneracy, ill-conditioning, and to achieve high-accuracy solutions with tolerances below 1e-8. The latest solver MadIPM.jl, targets large-scale linear and convex quadratic programs (LP / QP). All three solvers are based on second-order algorithms, enabling robustness and accuracy compared to purely first-order methods. We present performance results on real-world benchmark instances, demonstrating substantial speedups between CPU and GPU implementations, while maintaining high solution quality. **Audience Takeaway:** * Second-order methods scale on GPUs * Unified GPU solver suite (NLP / LP / QP) * Robust, high-accuracy solutions * Demonstrated real-world CPU–GPU speedups **Zoom: This is an online event.
