The rise of practical AI tools is exciting. Right now, tools like ChatGPT and other LLMs are our primary touch points with generative AI. But this doesn't mean we should only be generating content with LLMs (for context we'll also briefly touch on non-LLM probabilistic approaches as well). Since these powerful tools are new to all of us and none of us know the future, we'll explore together other ways of using generative LLMs and how this intersects with automation in general. **About David** David works with organizations in early planning for big transformations of complex suites of websites, applications, and systems.

### **What’s Unhappy Hour Breathwork, you ask? It’s our conscious breathing session to embrace our discomfort, sip some soothing tea, and dive deep into the beautiful chaos that is our childhood trauma, daddy issues, mommy issues, work stress, and those oh-so-fun failed relationships. Think of it as a cozy gathering where we can unpack our baggage together, all while sharing a laugh or two (or maybe a few tears).** Let’s be real life isn’t always sunshine and rainbows, and that’s perfectly okay.**We will give ourselves permission to be gloriously miserable for a full 90 minutes to** release the weight of our struggles. By using our own conscious breathing we’ll transform our experiences into something powerful and healing. Session will end with a soothing sound bath. Tea will be provided! Mark your calendars for this weekly dose of camaraderie and self-discovery. **What is Breathwork?** Breathwork falls under an umbrella term with many different marketing names and techniques. For this session we will be focusing in one technique while laying down on our back. This is NOT your typical relaxing breathing and it DOES NOT INVOLVE ANY YOGA movement. Breathwork takes us deep into the subconscious mind to make necessary changes and improve our lives by releasing emotional baggage and healing emotional wounds. When we tap into deep states of consciousness emotional release may take the shape of crying, laughing, even screaming. Many people like to call it years of therapy in one single session. It is very common to experience moments of clarity, bliss and many Aha moments during this session. Each person will experience something different with every session. All you need is an open mind and your own breathing to achieve results with no prior experience. Please note breathwork cautions before booking. **What you may experience during this session:** -Deep healing of emotional wounds, grief and traumas -Ability to connect to your higher self, Ancestors and the divine -Release anxiety -Improve emotional balance -Increased feelings of joy, happiness, and inner peace -Ability to create self-love and improve relationships **What to bring:** -Your own water bottle -A pen and notebook -A Yoga mat (or use one at the studio) -A blanket ( or use one at the studio) -Eye mask (if you have one) -Comfortable clothes to breathe and lay down **About Jenny Perez Curandera:** Jenny is a Curandera Shamanic Healer born into the Curanderismo Tradition.

**To receive future event updates, register on Luma:** **[https://luma.com/6qii7007](https://luma.com/6qii7007)** Let's discuss a podcast by Anders Ericsson, author of the renowned book "Peak: Secrets from the New Science of Expertise". Anders demonstrates that talent is overrated and peak achievement is dependent on a specific type of learning called "deliberate practice", and that your skill in any area is a function of the quantity and quality of “mental representations” you have for that activity. We explore the science of learning and of skill mastery -- how it happens, and how to do it. **Please watch this YouTube video (try 1.25x speed) before joining the discussion:** [https://www.youtube.com/watch?v=qiBne5EGBQ8](https://www.youtube.com/watch?v=qiBne5EGBQ8) If more than 8 people join the discussion, we will break out into smaller groups. **(max 8 people per group)** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 1. **Mastery requires focused quality over mere repetition. How can we ensure our daily efforts are intentional enough to foster genuine growth?** 2. **Effective mentors provide the roadmap for stretching our abilities. How might we better identify the guides who can point out our hidden obstacles?** 3. **Immediate feedback loops are essential for identifying and correcting technical errors. How can we build systems that provide the rapid insights necessary for our collective improvement?** 4. **Peak performance often requires unlearning habits that limit our ultimate potential. What fundamental methods could we refine to ensure our foundations support world-class excellence?** 5. **Growth occurs when we consistently set goals just beyond our current comfort zones. How do we determine the ideal balance between manageable challenge and productive discomfort?** 6. **Elite performance is sustained through intense concentration followed by restorative rest. How can we better value recovery as a vital component of our highest achievements?** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- To provide an enjoyable experience for fellow participants, here are three ground rules during discussion events: 1. Step up and step back. (If you feel that you’ve been talking too much, step back to listen more. If you feel that you’ve been relatively quiet, step up to share your perspective or ask a question) 2. Listen to understand, not to respond. 3. Be open-minded and value differences.

It has allowed them to heal confidently and consistently in the shortest learning time possible. These professionals find PRANIC HEALING® very effective and easy to apply. Other topics covered in PRANIC HEALING® Level 1: Energetic anatomy: You will learn to work with the network of chakras, meridians and auras to accelerate the healing processes of your body. Preventive healing: You will learn to remove the negative energetic patterns of a disease to prevent it from fully manifesting as a physical ailment. Self-Pranic healing: You will learn to apply these healing techniques to accelerate your own healing.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break.

These open mic–style events give anyone in the community up to **5 minutes** to present a project, share a tool, pose a question, or offer a perspective on the evolving AI space. No slides required — just a welcoming space to exchange ideas and keep the local AI conversation moving.
