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!

Join us for a Wellness Event combining gentle yoga + breathwork + meditation + sound bath.

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.

**A systemic constellation (also called Family Constellations) is a therapeutic group experience designed to uncover and resolve hidden family dynamics that may be influencing a person’s life.** Rooted in the work of Bert Hellinger, this method operates on the principle that unresolved traumas and patterns from previous generations can manifest in an individual’s relationships, health, or emotions. During the workshop, a facilitator guides participants as they explore these systemic entanglements using representatives—other group members who stand in for family members or key components of their issue. Through this process, participants gain deep insights into their energy field systems, fostering healing and a sense of resolution. These workshops provide a safe and supportive environment for self-discovery and transformation. Participants often experience profound emotional shifts as they witness and engage in the unfolding dynamics of their lives stories. By bringing unconscious loyalties, unresolved grief, or burdens to light, Family Constellation work helps individuals break free from limiting patterns, fostering greater harmony, self-acceptance, and a renewed sense of belonging. Whether attending as an active participant or as a representative, individuals often leave with a deeper understanding of their own lives and relationships. **Must register online FEE: $65** **Learn more and register** [here!](https://www.tealcenter.com/classes-and-events/)

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Investors move fast. Most agents don’t.** If you can’t evaluate a deal quickly and confidently, you lose credibility—and the opportunity disappears. Deal or Disaster teaches a simple, repeatable framework to determine in minutes whether a deal prints money or burns it. In this session, you’ll learn a 5-minute investment evaluation system that works across flips, rentals, BRRRRs, wholetails, and creative deals. The goal isn’t perfection—it’s speed, clarity, and credibility. We’ll break down: * How to identify the investor’s true goal before running numbers * A fast, reliable method to estimate ARV with confidence * How to calculate the real all-in acquisition cost * Simple heuristics to ballpark rehab and improvement costs * The key metrics that reveal whether a deal works—or should be killed You’ll also learn the most common red flags that signal bad deals, thin margins, and hidden risk, so you know when to pause or walk away. When you can analyze deals in minutes, you earn authority, build trust, and become indispensable to investors. Speed creates opportunity—and opportunity creates repeat business. If you want to move from real estate generalist to trusted investment strategist, this session gives you the framework to do it. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
