[Click To Learn More About & Get Your Tickets](https://aagc.africa/?mc_cid=294c8e0d0d&mc_eid=UNIQID)
This May in Accra, as part of Africa Day celebrations, the Timeless Women of Wonder Foundation (TWOWF) is convening leaders, investors, policymakers, and operators from across sectors in Africa through the Accelerate Africa’s Growth Connect (AAGC)—a platform designed not just for dialogue, but for partnerships and tangible outcomes.
If you’re looking to explore investment and trade opportunities, build meaningful relationships on the continent, or deepen your engagement with Africa’s growth story, this is your invitation into the room where that becomes possible.
AAGC sits at the intersection of influence, access, and execution—bringing together those actively shaping Africa’s economic transformation and global competitiveness.
What makes it stand out isn’t just who is in the room— it’s what the room is built to enable. Across two powerful days, you’ll gain direct proximity to:
-Policymakers and government leaders shaping national agendas
-Investors and business leaders unlocking capital and opportunity
-Innovators and entrepreneurs building across key sectors
-A global network aligned around growth, collaboration, and impact
-Curated deal rooms connecting capital with real opportunities
From high-level dialogue to investor forums, curated networking, and deal rooms — this is where ideas evolve into partnerships, and partnerships translate into impact.

It’s Monday! Let’s go Bowling!
**!!Please read to the end for important information!!**
Monday night bowling?! What a great idea! Join us for good times and lousy bowling.
Lane assignment may vary each week. To find us, tell the front desk you are here for the "OG Lousy Bowlers."
We often have a wait list. Too ensure that those who want to attend get a chance to do so:
please confirm your plans at least two days in advance (Saturday) of each event and update your RSVP if you can no longer attend. Members will be removed from the group after their second unannounced no-show. **Consistent RSVP changes less than two days before our events will result in a warning, after which they will be considered as a no-show.**
***Check and keep checking***
If you are on the wait list, be diligent in checking Meet Up to see if you have been moved to "Going"! Meet Up email and app notifications are often very slow. Please don't rely on an email or notification to inform you that you are "Going". Open the event and click on the Attendees list to see if you are "In".
Frequently, wait listed members get "in". If you are on the wait list, check Meet up. Lack of paying attention to when you get off the wait list will not be an excuse for being a No Show.

Your Evals Are Bad: Evaluation and the Model Development Lifecycle
**REGISTER AT THE LUMA EVENT PAGE!!!**
https://luma.com/27ja5gwl
Join us for an exciting talk by Mary Gibbs, Senior Applied Scientist at Relativity.
**Agenda:**
6:00 - 6:30 PM - Welcome and mingle
6:30- 6:45 PM - Introductions
6:45 - 7:30 PM - Talk
7:30 - 8:00 PM - Wrap up
**Description:**
If you have ever shipped a model, watched your metrics improve, and later learned from your users that something was wrong, the metrics were always wrong. You just didn’t know it yet. An evaluation consists of three components, a benchmark, a scorer, and a claim about what a score represents. Each component has its own weaknesses. Benchmarks can suffer from narrow coverage, contamination, or saturation. Scorers are often chosen for ease of automation or computation rather than for their alignment with user outcomes. And the claim connecting a score to reality is rarely made explicit. These gaps compound across the model development lifecycle. When metrics improve, teams treat that as a signal and optimize directly against it, which is how a measurement problem becomes a model problem. This talk maps where evaluations can go wrong, considers counterarguments, and ends with practical advice for building better ones.
**Speaker Bio:**
Mary is a Senior Applied Scientist at Relativity, tackling data science challenges in the e-discovery and legal tech space.

Mary's experience spans various domains. She has developed data science solutions related to job search and career progression at Teal, cybersecurity challenges at LiveAction Software, and commercial and government consulting at Mosaic Data Science.

Disaster+Travel+Wilderness First Aid (In-Person) Certification Course
Hands-on learn how to save life & limb, when mired in the wilderness of an urban disaster zone, travel or rural area far from hospital, or natural area miles from an access point, during the critical minutes or hours before ambulance arrival. Come away with actual do-it-yourself care-giving skill and confidence, and 2-year SOLO certification. Counts as WFR Recertification, too. No prerequisites.
YOUR SPOT IS NOT RESERVED UNTIL YOU'VE COMPLETELY REGISTERED AT WWW.SOLOWFA.COM \***Spaces are limited. REGISTER: www.solowfa.com or 434.326.4697**
Can't make these dates? Check out more course locations and dates on our website.
WHO: Open to the general public, adults & teens with solid attention spans. Know your loved ones are safe wherever they are.
WHY: Mired in a disaster zone, travel or rural area far from a hospital, or natural area miles from an access point ... accidents, destructive weather, and terrorism happen, and all-too-often members of a group are not capable of dealing with the emergency. This leads to improper care of the patient, and endangers the entire group. Many recreational accidents are preventable, and improper care of trauma can compound even simple injuries. Very few first aid programs actually address the issues of providing emergency care in a setting where 911 is overwhelmed or not immediately reachable. In this course, classroom instruction and Q&A are interwoven with practical work and problem-solving exercises. Hands-on experience - a most powerful learning tool - during scenarios comprise \~50% of class.
TIMING: This is a 2-day class, Saturday and Sunday, 8:00am -7pm each day.
Fee: $295 (Earlybird)

Young Adult Daylong Retreat
Young Adult Daylong Retreat
During this daylong mindfulness retreat, we will come together with others in the young adult phase of life (20s and 30s) to share in sangha (community). We will be focusing on connecting with our inner landscape through experiential and grounded contemplative practices.
This daylong mindfulness retreat will include:
* Guided meditations
* Dharma talks
* Periods of supportive silence
* Opportunities to share in small groups and connect with others
* Mindful movement
Through these practices, we will build a strong relationship with ourselves and our inner landscape, allowing us to deepen our capacity to be with ourselves and others no matter the circumstances. While this is an inner journey, it's and inner journey that we are all on together and can better achieve with the support of community.

Meaningful Conversation and Coffee - Northside Social Falls Church
**Join us in Falls Church for conversations that go beyond small talk.**
Higher Grounds – Falls Church is where this growing network of gatherings began: a space for thoughtful, authentic dialogue about what matters most. Whether we’re exploring the nature of happiness, the challenges and possibilities of midlife, spirituality, culture, capitalism, parenting, or the role of art and travel in a meaningful life, every conversation is shaped by the people in the room.
There’s no set leader or rigid agenda—just a shared commitment to listen as much as we speak. We start with brief introductions focused on what makes you *you* (not your LinkedIn bio), then dive straight into whatever is on people’s minds. The direction of each meetup emerges organically, making every event unique.
MANDATORY: PLEASE REVIEW OUR COMMUNITY GUIDELINES IN THE GROUP DESCRIPTION. Everyone is expected to engage in respectful conversations and listen deeply as well as share. We have a zero tolerance policy of sexual harassment and hate speech.
Come ready to share, reflect, and connect with others in Falls Church who are also seeking deeper conversations.

**Abstract**
Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod.

What Causes Your Roller Coasters in Life?
Do you sometimes feel like you do well in life then something happens and you slide back, never quite getting ahead.
At this Meetup you'll find out how to identify what actually causes the lows, the highs and everything in between. More importantly you’ll get the secret of how to gain control over your life so the highs are higher and the lows go away.
Wouldn’t it be nice to stop the wild roller coaster ride for good? Or at least make it a fun roller coaster ride, with more ups and downs.
There is a hidden factor that will be going over and you’re going to be quite surprised what it is and how much it affects your life.
Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there.
This group is hosted at the Dianetics and Scientology Life Improvement Center.
