Intro to Shaders in Unity
This meetup is a beginner-friendly, hands-on workshop focused on building shaders in Unity using Shader Graph. Instead of slides or theory-heavy lectures, we'll build real shaders together step-by-step.
The format is structured but interactive. You'll watch a quick demo, then build each shader yourself with guidance. By the end, you'll have created multiple shaders you can immediately use in your own projects—and understand how to make more.
**What to Expect:**
* Build 4–5 complete shaders from scratch
* Color tints, snow accumulation, scrolling water, dissolve effects, and more
* No prior shader experience required
* Checkpoint files provided if you fall behind
* Resources for continued learning
All experience levels are welcome. Whether you've never opened Shader Graph or just want to fill gaps in your knowledge, this is a supportive space to learn by doing.
**Food and drinks provided. Join us to learn, build, and level up your shader skills.**
I added the Unity project to the repo here - https://github.com/EricJRico/IntroToShaders.git
This is what we'll be using for the session.
Free In-Person Events: How to Let Go of the Past and Move Forward
The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience.
And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree.
In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again.
Examples of painful experiences include:
* A broken relationship or divorce.
* Death or loss of a loved one.
* Death of a pet.
* A sudden shock or bad news.
* A betrayal.
* Being part of an abusive relationship.
* A bad injustice.
* Loss of a job, position or business.
* A grave illness or injury.
The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is sponsored the Dianetics & Scientology Self-Improvement Center.

From Stability to Stewardship
A Biblical & Practical Path to Financial Freedom
This is not just a money class.
This is a restoration space.
The I AM Worthy of Ownership™ Path is a 12-step, sister-centered journey for women who are ready to build financial stability without shame, fear, or pressure—and to do it in a way that honors both wisdom and the spirit.
Many women don’t struggle with money because they lack discipline or intelligence. They struggle because of unhealed experiences, survival patterns, and the quiet belief that they are “behind” or “disqualified.” This series gently challenges those beliefs while offering practical tools for peace, clarity, and long-term planning.
Together, we will talk honestly about:
Releasing shame and money anxiety
Building stability as a form of self-respect and spiritual discipline
Understanding money as a tool, not a source of worth
Managing debt with clarity instead of condemnation
Preparing for life’s unexpected moments without fear
Laying a calm foundation for future ownership and legacy
Each session blends practical financial education with reflection, conversation, and encouragement. There is no pressure to share personal numbers or experiences. You are welcome to speak, journal quietly, or simply listen.
This is not about hustle.
This is not about perfection.
This is about alignment, wisdom, and peace.
Who this series is for:
Women who are starting over or rebuilding
Women who want stability without stress
Women preparing for future ownership or housing decisions
Women who want their financial lives to reflect wholeness, not fear
No prior financial knowledge is required.
Come as you are. Bring a notebook.
Leave a little lighter than you arrived.
Light refreshments will be served along with 30 minutes of networking.

Contra dance Feb. 21 (First Unitarian Universalist Church) note new time!
# **Band: Old Possum's Menagerie; Caller: Richard Ades**
Beginner lesson at 1:30, regular dancing begins at 2:00 pm
NOTE THAT WE ARE TEMPORARILY DANCING IN THE AFTERNOON INSTEAD OF EVENING. Dance with us in the afternoon then you can still go out in the evening!
**Sponsor: All Soles Contra and Square Dancing, First Unitarian Universalist Church, 93 W. Weisheimer Rd., Columbus OH 43214**
WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing!
Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor.
Be sure to come for the beginner's lesson from 1:30 - 2:00, followed by dancing 2:00 - 430. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner.
Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot.
Please bring your own refillable water bottle.
Morning people unite!! 🐤 ☕ + 💬 @ Good Cafe

Spec-Driven Development with GitHub Spec-Kit - Barret Blake
**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**
*Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation*
Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. 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.
