The Kennedy Center was supposed to present this play last year with a cast from Broadway, but the producers cancelled. Luckily, Theater J has taken up the baton. I saw it a few years ago, I believe at Mosaic, and it is laugh-out-loud funny.

The Eureka Day School in Berkeley, California, is a bastion of progressive ideals: **representation, acceptance, social justice**. In weekly meetings Eureka Day’s five board members develop and update policy to preserve this culture of inclusivity, reaching decisions only by consensus. But when a mumps outbreak threatens the Eureka community, **facts become subjective and every solution divisive**, leaving the school’s leadership to confront the central question of our time: **How do you build consensus when no one can agree on truth?**

Tantra is a special inner science that teaches how we can change our mind, ourself and our life. Although the idea of Tantra is very popular these days, many people misunderstand its real meaning and so it is often misused. In reality, Tantra is a very special practice that harnesses the power of our imagination and the power of Buddha’s blessings to quickly lead us to a state of permanent peace and happiness. The profound Tantric practices show us how to overcome the limiting views of ourselves, others, and the world around us that give rise to fear, anxiety, and other painful thoughts. Tantra helps us create positive energy and wisdom through special meditations that lead us quickly to enlightenment. This series is open to everyone and in particular provides a great opportunity to prepare those who wish to receive Highest Yoga Tantra Empowerments. March 5: What is Tantra?

Treat your children to GALita’s ***Séneca, ratón de biblioteca (Séneca, The Library Mouse)***, a bilingual play by Chilean playwright Jorge Díaz with original music by José Gabriel Lora. Directed by Elena Velasco, this fun-filled play touches on the importance of reading and respecting differences, and runs March 14 through March 28, 2026. When a brainy library mouse meets a swaggering crew of street mice, sparks fly and stories take off—spilling from the shelves into a world of comic chases and big laughs. Along the way, unlikely friendships form and lessons unfold about listening, learning, and belonging. Brought to life through imaginative puppets and original music, ***Séneca, The Library Mouse*** invites young audiences to celebrate difference, delight in the joy of books, and discover confidence and pride in who they are—proving that brains, creativity, and curiosity can be just as powerful as bravado. **PERFORMANCES:** Weekdays from March 16-20 and March 23-27 at 10:30 am, and Saturday, March 14 & 21 at 3 pm and Saturday, March 28 at 2 pm. This family show is about 60 minutes long and suitable for ages 5 and up! **TICKETS:** General admission tickets are $10 children and $12 adults. **[GET TICKETS HERE](https://ci.ovationtix.com/35923/production/1245619)** **CAST:** Daniela Lock as Séneca, Delbis Cardona as Rafael, Ramón, and Raúl, Máximo Cáceres as Benigno (Dog), Rachael Small as Bellaco (Cat), and H.

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid.

Projects that are over budget, delayed, or that fail to scale past the POC phase are very common. In many of these scenarios, choosing the right approach can be as critical as the solution itself. Should you build a tailored machine learning model, leverage the power of large language models (LLMs), or integrate with AI copilots? Each option has unique strengths, trade-offs, and resource requirements, and the key to success lies in aligning your choice with your business goals and technical constraints. In this talk, we will go beyond the basic concepts and definitions to provide a practical guide that allows attendees to navigate these decisions through real-world case studies. We will examine scenarios in which different AI paradigms were chosen, discuss the factors that influenced those decisions, and outline the process for evaluating needs, constraints, and outcomes. From assessing data availability and team expertise to balancing cost and scalability, you'll gain insights into the critical considerations that guide the selection process. By the end of this session, you’ll have a clear process for determining whether machine learning, LLMs, or copilots are best suited to your AI challenges and understand the resources and strategies needed to bring your chosen solution to life. This talk is ideal for decision-makers, technical leads, and innovators seeking to demystify AI implementation and maximize the impact of their investments.

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.
