DoJo (Informal Python Meeting)
**New Dojo Location!**
**Draft Day Columbus**
1130 Dublin Road
Columbus, OH 43215
We're going to try a new dojo location for a few weeks and see how it works
Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

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.

February Book Club Meetup
Welcome, readers!
Our February read is **_1984 by George Orwell._**
In 1984, George Orwell imagines a world where the government watches everyone, rewrites reality, and punishes even private thoughts. Winston Smith dares to question this system, believing that truth and love might still exist. His rebellion draws him into a chilling struggle against a power that knows him better than he knows himself. The novel leaves readers asking whether freedom is possible when reality itself can be controlled.
Looking forward to discussing with everyone!
We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **drinks must be purchased at the bar.**
Happy reading! 📖

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
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 created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
Fun Friday: EPiC: ELVIS PRESLEY IN CONCERT vs SCREAM 7 at Lennox Phoenix!
Our Fun Friday event just got better! Our event has been expanded to include your choice of TWO great films: EPIC: ELVIS PRESLEY IN CONCERT or SCREAM 7! EPiC: ELVIS PRESLEY IN CONCERT is directed by Baz Luhrmann and uses rare and previously unseen interviews and videos of Elvis in concert to create “one of the most exciting concert films you’ve ever seen!” SCREAM 7 assembles previous cast members and great newcomers for the next chapter of one of the most reliable horror franchises! In this film, a new Ghostface killer emerges with the daughter of Sidney Prescott becomes the next target. Here are details, trailers and our plan for this event:
EPiC: ELVIS PRESLEY IN CONCERT uses rare and previously unseen interviews and concert footage to create “one of the most exciting concert films you’ve ever seen!” In addition to the stellar reviews, the film was runner up for the People’s Choice Award for Documentaries at the Toronto Film Festival. The film is earning a Certified Fresh 95% positive rating on Rotten Tomatoes (and a 99% positive rating audiences)! The RT site declares, “Resurrecting Elvis Presley at the peak of his showmanship, Baz Luhrmann's truly epic concert documentary restores some joy into The King's legacy.” Film Threat adds, “The most beautiful thing about EPiC: Elvis Presley in Concert is that in connecting us so intimately to the man and showing him in all his complexity, Luhrmann cuts through the baggage we bring and gives us a fresh look at one of the most fascinating and accomplished musicians who has ever lived.” TRAILER: https://www.youtube.com/watch?v=NmqWusmzp0k
SCREAM 7: This is an opening night showing of next chapter in one of the best and most reliable horror franchises! In this film, Sidney Prescott has built a new life in the quiet town of Pine Grove, Indiana, until a new Ghostface killer begins to target her daughter, forcing her to face her past to end the killings once and for all. The stellar ensemble case includes Neve Campbell, Jasmin Savoy Brown, Mason Gooding, David Arquette, Matthew Lillard and Courteney Cox all reprising their roles from the previous films, along with Isabel May, Anna Camp, Mckenna Grace, Asa Germann, Celeste O'Connor and Joel McHale! TRAILER: https://www.youtube.com/watch?v=CsHBPYVFd3Y
PLAN: For the bite before the show, BOTH GROUPS meet in the Bar Area at BRAVO at 5:00pm. Should be pretty open, but keep an eye out for us and we’ll keep one out for you! For EITHER MOVIE, please purchase your ticket for the 6:30pm showing and meet in the lobby area between 6:10 and 6:20pm. Advance ticket purchase advised. Once you have yours please list your movie of choice and seat number in the Comments section of this event.
Should be a fun one! Look forward to seeing you there, Dan

I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve.
THANK YOU: This CMG Gives Back event provides an opportunity for YOU to get involved in helping others! Benefits go well beyond the help we give to others. Volunteering provides a wide range of personal benefits, including positive effects on mental and physical health, reduced stress/depression/anxiety, increased happiness and improved purpose, life-satisfaction and personal well-being! Plus, the opportunity to get involved, connect with others and help those in need.
PARTNER AGENCY: This event is hosted by Lutheran Social Services (LSS), which serves thousands of people in need each day in 27 Ohio counties by addressing the four core societal issues of food, shelter, safety and healing. LSS offers food through the LSS Food Pantries, housing and supportive services through LSS Faith Mission and LSS Faith Mission of Fairfield County homeless shelters, domestic violence services through LSS CHOICES for Victims of Domestic Violence, senior living and health care, affordable housing communities, and other services that uplift families and strengthen communities.

CBusData - Discover the Power of Window Functions
Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems:
* Using running totals
* Performing operations in intervals
* Identifying data gaps and islands
* Performing aggregates without losing detail
Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
