Tired of `git rebase` conflicts? Wish you could edit your commit history without fear? Join us for a hands-on introduction where we'll cover some \`jj\` basics and get to use it in action! \`jj\` is a modern version control system that's compatible with Git but designed from the ground up to be: simpler and easier, but also more powerful ! Pretty bold claim, right ? In this hands-on session, we'll explore: * What jj is and why developers are excited about it * Basic jj commands and how they compare to Git * Setting up and using jj with Git repositories * (yes, you can use it on your existing projects!) * (and, no, the rest of your team doesn't have to adopt it!!) * Core workflows: creating commits, viewing history, and making changes * A quick look at what makes jj different (automatic commits, simpler history editing) **What to bring:** * Your laptop (ideally with \`jj\` [installed](https://docs.jj-vcs.dev/latest/install-and-setup/) ) * Curiosity about alternative version control workflows **Who should attend:** Developers of all levels who use Git regularly and are curious about modern alternatives. Whether you're frustrated with Git's complexity or just interested in exploring new tools, this workshop will hopefully entice you to try out something new that will spice up your daily workflows! No prior jj experience required—just familiarity with basic version control concepts. **Sponsors** Our sponsors for this meetup are [Yodeck](https://www.yodeck.com/) \- who are not only kindly providing the venue\, free of charge\, but who will also treat us to some snacks / drinks for the networking session after the meetup\! Do stick around and say hi!

Based on my MBA research, this talk explores the current state of Agile adoption in Greek organizations. Drawing on survey data from executives and Agile team members, it examines how Agile is practiced today, which frameworks are in use, what success looks like and where things quietly start to break down. The research reveals a growing gap between how leaders believe Agile is working and how teams actually experience it. Using a data-driven lens, we explore the real challenges of scaling Agile in Greece, the underestimated role of culture and people, and what it takes to build truly adaptive, innovation-driven organizations. While the data was collected in Greece, the findings are compared with some of Europe’s most mature Agile environments, particularly Denmark and the Netherlands. This comparison places the Greek ecosystem in a broader EU context, distinguishing local constraints from universal Agile challenges and highlighting what can realistically be adapted. **What you’ll take away** * Uncover critical perception gaps, such as the ‘Culture Blind Spot’, that are holding teams back without leadership realizing it. * See the shared roadmap executives and teams actually agree on for scaling Agile beyond pilots and isolated successes * Identify the human factors currently undervalued, contributing to stalled innovation in the majority of organisations and talent loss eventually. * Learn how to move beyond the ‘delivery’ toward healthier, more resilient organizations This session is ideal for leaders, managers, Agile practitioners, and anyone interested in the future of work and organizational agility.

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.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. (NOTICE - Location change!) This session will be at the Karl Road Branch of the Columbus Library in the Conference Room 2.

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.

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
