This month, we'll have a recorded talk, followed by discussion, on API design and single-header libraries. How should we structure and program libraries to impose as few usage constraints as possible? We’ll look at [the STB libraries](https://github.com/nothings/stb) and other examples as case studies. We're still at the West End Library - see the location in the sidebar for details. **Agenda:** \- 2pm \- 3pm: Library discussion \- 3pm \- 4pm: Open\-ended discussions\, presentations\, etc\. \- 4pm \- whenever: We'll go get food nearby\! **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

Reclaim your soul’s truth.** Beneath all the noise, the patterns, and the pain, your soul has never stopped whispering. It holds the memory of every choice, every wound, every triumph across time. This vibrational archive—your Akashic Records—awaits you. And within them: clarity, healing, and a return to the Divine spark of who you truly are. Let’s take a breath and reflect… \~Have you been feeling like you're moving through life in a loop—taking one step forward, only to be pulled back again and again? \~Does life feel like an ongoing storm of confusion, struggle, or emotional unrest? \~Do you long for heartfelt, soul-level connection—but feel it remains just out of reach? \~Are you living the life your heart calls you to…or the one others expect? **If you’ve felt this, take comfort: you are not broken. You are awakening. You’ve been guided to this moment for a reason. Your soul knows it's time to return home to your truth.** **\*\*Welcome to the Akashic Records\*\* a timeless sanctuary of compassion, wisdom, and love.** In this deeply healing workshop, you're invited not just to explore your story—but to rewrite its energetic imprint. Guided by the compassionate presence of **Bill Sanda**, you'll step into a space where healing is not only possible, but inevitable—when met with an open heart. This isn’t just another offering. This is a soul-remembrance. During our time together, you will: ✨ **Uncover the hidden patterns of your past**, including the emotional echoes, ancestral threads, and past-life imprints that continue to influence your present reality ✨ **Liberate yourself from repetitive cycles** of fear, doubt, or stagnation, so you can move forward in alignment with your soul’s highest expression ✨ **Receive healing directly from your Akashic Records**, reconnecting to your innate wisdom and Divine blueprint ✨ **Remember who you are beyond this lifetime**, as insights from past incarnations help you navigate your current path with grace ✨ **Experience the sacred sound of Light Language**—a celestial, soul-coded vibration that speaks beyond the mind, clearing density, activating remembrance, and harmonizing your energy at the DNA level Bill’s sacred gift of channeling the Akashic Records—woven together with the high-frequency transmission of Light Language—creates a multidimensional space for profound transformation. You’ll also receive personal attention during the workshop through mini-healing sessions, and we'll culminate in a group integration, inviting a collective shift in vibration and consciousness.

The shift happening for each person was actually physically visible.”* — *Cindy W.* *“Finally, I understand what has been causing the sabotaging behaviors. Two days later, I’m clearer and more spiritually connected than I’ve ever been. Thank you, Bill, for your healing gifts.”* — *Wendy W.* ***About Bill Sanda*** *A lifelong seeker and heart-led healer, **Bill Sanda** walks with humility, clarity, and deep reverence for the sacred. His journey has led him to study with some of today’s most respected spiritual masters, but it was through divine revelation that his ability to work within the Akashic Records and transmit Light Language fully emerged.* *Bill now offers this work as a gift of service—to support others in awakening to their truth, releasing what no longer serves, and remembering the wholeness that has always been within. His mission is simple and powerful: to support your healing on all levels—**emotional, physical, mental, and spiritual**—so you can live more aligned, more free, and more fully alive.* **Investment: $75** Pre-registration and Payment required: [https://www.wellnessliving.com/rs/event/teal_center?k_class=919488](https://www.wellnessliving.com/rs/event/teal_center?k_class=919488)

Title: What Is Space Density? From Medium Ontology to the Spacetime Constant K Date: March 8 2026 10:00 am - Noon EDT Abstract: Spacetime plays an active role in gravity, wave propagation, and quantum behavior, yet physics rarely treats it as a physical medium with intrinsic properties such as density or inertia. This missing layer creates a major conceptual gap—especially when interpreting large-scale gravitational anomalies that are often attributed to dark matter. In this talk, Lynn will propose a clear conceptual framework for what it means for spacetime itself to possess a density-like property, and Lynn will explain why Unified Field Theory (UFT) naturally encodes this property through the constant K, called the spacetime background inertial intensity constant. Lynn will introduce a space-density constant μₛ as a universal property of space itself—independent of matter, energy density, or gravitational sourcing. However, μₛ cannot be inserted directly into field equations, because it belongs to the ontological level: it describes what space is, not how spacetime responds. To influence dynamics, μₛ must be expressed geometrically. This leads naturally to K, which carries the same physical meaning but operates at the level required by geometric field dynamics. This is a change in representation—not the addition of new physics. This approach provides an alternative way to interpret dark-matter-like effects. Instead of requiring unseen particles, gravitational anomalies can be viewed as consequences of spacetime’s intrinsic rigidity and its global, cumulative response in large coherent systems such as disk galaxies. In local, weak-field environments, standard Newtonian and relativistic gravity remains an effective approximation. The goal of the talk is not to present a final empirical model, but to clarify the physical meaning of spacetime constants and open discussion between UFT and mainstream theoretical physics. Keywords: Spacetime ontology; space density; intrinsic spacetime properties; Unified Field Theory (UFT); spacetime background constant K; geometric response; gravitational coupling; dark-matter-like phenomena Brief Biography Lynn Lou Beran is a Senior IT Security Analyst and an author, translator, and editor working at the intersection of science, engineering, and communication. She translated and edited multiple editions of Zhang XiangQian’s Unified Field Theory and co-authored recent manuscripts developing a geometric, motion-based view of physical reality. Lynn’s broader work focuses on making advanced ideas accessible without sacrificing rigor, and on connecting conceptual insight to testable predictions and practical tools.

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.

**Our March pick is *God of the Woods* by Liz Moore.** **This month’s novel is an award-winning literary mystery that blends family drama with psychological suspense. It explores women’s voices and relationships while delivering an exciting, eerie, and deeply suspenseful story. The book is 576 pages in print or 14 hours and 35 minutes on audiobook.** Early morning, August 1975: a camp counselor discovers an empty bunk. Its occupant, Barbara Van Laar, has gone missing. Barbara isn’t just any thirteen-year-old: she’s the daughter of the family that owns the summer camp and employs most of the region’s residents. And this isn’t the first time a Van Laar child has disappeared. Barbara’s older brother similarly vanished fourteen years ago, never to be found. As a panicked search begins, a thrilling drama unfolds. Chasing down the layered secrets of the Van Laar family and the blue-collar community working in its shadow, Moore’s multi-threaded story invites readers into a rich and gripping dynasty of secrets and second chances. It is Liz Moore’s most ambitious and wide-reaching novel yet.
