Tech & Truth Café
An open space for real conversation about how technology is shaping our world, and how we can respond with wisdom, purpose, and values.
## COMING UP:
## Life with Augmented Intelligence
**Shaping how we live, work, and build in an AI-driven world**
From assistants → to collaboration → to autonomous systems
***
**A different way of thinking, working, building.**
Most people are still using AI at the surface.
Answers. Shortcuts. Quick help.
But underneath, work is starting to look different:
* systems instead of tasks
* collaboration instead of commands
* design instead of effort
This is a space to step into that.
Not a workshop.
Not a panel.
A place to see what’s emerging, hear how others are thinking, and explore what it means for your own life and work.

ASL Brunch on Sundays in Greenbelt
Join our ASL Brunch on Sundays in Greenbelt! All ASL users and learners are welcome.
Brunches are alternately held at two restaurants in Greenbelt, both in the same town plaza.
ODD WEEKS: 1st, 3rd, and 5th Sundays, we meet at Cedars of Lebanon, 103 Centerway.
EVEN WEEKS: 2nd and 4th Sundays, we meet at New Deal Café,113 Centerway.
We are the Greenbelt ASL Community, a group of both Deaf and hearing people who hang out, chat about everyday goings on, trade stories, get to know each other better, and of course, enjoy food together. Many members use ASL as their primary language, several are interpreters or other fluent ASL users, while others are ASL learners who wish to improve their skills while making new friends.
Before or after brunch, you can visit the farmer's market and small coop grocery store in the plaza.
Please RSVP so we can contact you via email if needed.
Our group is on Facebook as Greenbelt ASL Community. Some long-time group members don't mark their attendance here, so feel free to stop by even if you don't see others who have RSVP'd on Meet-up.
Mantra Drum Circle for Rain
Join us to drum for rain! The drum circle will be at the Guru Rinpoche statue at the entrance to the Peace Park, across the street from the temple. We will be chanting sacred mantras as we drum, praying for abundant rain to ease the drought.
All are welcome!
Please bring any percussion instruments you have - the more the merrier! If you don't have any drums, there may be extra available. Either way, you can chant along with everyone. Seating is limited so we recommend bringing a chair or blanket to sit on.
In the event of inclement weather, we usually drum as long as we can before the storm starts, or wait it out and start a little late. We hold out until the last minute to cancel so if the weather seems iffy, keep an eye on our Facebook page for announcements.
The DC region is currently experiencing moderate to severe drought. Many other regions of the world are also experiencing drought conditions. We will dedicate our prayers to bringing life-giving rain to all who need it!

In Person: Partnering with Spirit to Solve Problems
“When you open yourself to divine truth, the mere fact that you can
identify a problem means that you have the solution within you. What
you are attempting to achieve through the Spiritual Exercises of ECK is
the expansion of consciousness whereby you can better see the
solution to your problem.”
─ Harold Klemp, The Golden Heart, p. 88
You are Divine Soul – and have the godlike power of creative imagination within
you. Using this power, you can find solutions for every problem and take charge
of your own life.
But how do you actually do it? How can you best tap the creativity of your true
self, and manifest a happier and more productive life for yourself now?
During a lively discussion, we’ll explore ways to more consciously connect with
the Divine power, more effectively address our fears, and transform the way we
identify and work with problems.
All attendees will receive a free copy of the book, “ECK Wisdom on Solving
Problems.”
We look forward to seeing you there!

Data & Analytics Wednesday - Mapping and Dashboards
**Total Eclipse of the Chart: School Redistricting Dashboards**
In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these.
While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics.

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs.
This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context.
We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing.

CBusData - Practical AI for Power BI Developers
Practical AI for Power BI Developers
A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective.
This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly.
Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
