Time Series Analysis

MDC DSA’s Labor Magazine Discussion Club seeks to provide a monthly discussion space to think through and debate tactics, strategy, and theoretical analysis within the currently existing Labor movement. We hope to be a nerve center for germinating new and incisive analysis useful for the cause of workers self-emancipation. All are welcome to join the club’s meeting, where we will discuss 3 articles from labor magazines currently circulating. For more details and links to the readings, check out [the group's info doc](https://docs.google.com/document/d/1rq5JzlubZrLNML0EbGUHiNvXNC42VRz8bmJgLH4GE-s/edit?tab=t.0).

Details Location: Crimson Whiskey Bar (Either the downstairs whiskey bar, or main floor bar, TBD) The purpose of Thinkers and Drinkers is to facilitate casual but meaningful and interesting conversations with other people in a face-to-face setting. The topics cover a wide variety of issues and are different for every meeting. While conversations may get heated at times, we ask that all members be respectful of each other and refrain from personal insults. Topic: The Gamblification of Everything Gambling is certainly not anything new. The idea of making a quick buck based on a game was just as appealing to ancient Mesopotamians as it is to estranged uncles who moved to Las Vegas. In the US, sports gambling has exploded since the Supreme Court ruling in 2018 that struck down a nationwide ban on sports betting. A [survey](https://sri.siena.edu/2025/02/18/22-of-all-americans-half-of-men-18-49-have-active-online-sports-betting-account/) released last year revealed 22% of Americans had an active sports betting account, and nearly half of men aged 18-40. This growth has mainly been associated with mobile apps like DraftKings, which thrive on allowing many small bets anytime, anywhere, on people's phones. Unsuprisingly this has led to a dramatic increase in gambling addictions for people in their 20s. It's not just sports gambling that has taken off, but other new betting markets like Polymarket that allow users to bet on anything from elections and international conflict to earthquakes and video game release dates. Meme/Joke markets like "[Whether or not Jesus will return this year](https://polymarket.com/event/will-jesus-christ-return-before-2027)" have popped up that have volume in the tens of millions of dollars. With prediction markets becoming legal in the US after a CFTC decision in October 2025, these prediction markets are set to grow more, both in terms of volume and the number of things they bet on. Questions to Consider: * Are sports gambling addictions overhyped? * Should the federal government put restrictions on sports betting and prediction markets? * How does the role of social media influence people's views on taking extraordinary risks to get rich fast? * What type of impact do prediction markets have on the things they are trying to predict? Could this provide adverse incentives for someone to influence an election just because of the bets they have taken?

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.

Learn to manage stress and achieve self-growth through simple relaxation and Meditation. Heartfulness Meditation is a simple, modern, methodical approach to meditation. Rather than homing in on your breath or repeating a mantra, you simply focus inward, on your heart, to cultivate inner strength and serenity. Heartfulness meditation is gaining traction in recent years. It focuses on the heart, allowing individuals to connect with themselves on a deeper level, and ultimately achieve peace, relaxation, and clarity. It is a practice that encourages patience, self-compassion, and acceptance, helping cultivate a deeper appreciation for the present moment. This practice is offered with love and at no cost

**To receive future event updates, register on Luma:** **[https://luma.com/6qii7007](https://luma.com/6qii7007)** Let's discuss a podcast by Anders Ericsson, author of the renowned book "Peak: Secrets from the New Science of Expertise". Anders demonstrates that talent is overrated and peak achievement is dependent on a specific type of learning called "deliberate practice", and that your skill in any area is a function of the quantity and quality of “mental representations” you have for that activity. We explore the science of learning and of skill mastery -- how it happens, and how to do it. **Please watch this YouTube video (try 1.25x speed) before joining the discussion:** [https://www.youtube.com/watch?v=qiBne5EGBQ8](https://www.youtube.com/watch?v=qiBne5EGBQ8) If more than 8 people join the discussion, we will break out into smaller groups. **(max 8 people per group)** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 1. **Mastery requires focused quality over mere repetition. How can we ensure our daily efforts are intentional enough to foster genuine growth?** 2. **Effective mentors provide the roadmap for stretching our abilities. How might we better identify the guides who can point out our hidden obstacles?** 3. **Immediate feedback loops are essential for identifying and correcting technical errors. How can we build systems that provide the rapid insights necessary for our collective improvement?** 4. **Peak performance often requires unlearning habits that limit our ultimate potential. What fundamental methods could we refine to ensure our foundations support world-class excellence?** 5. **Growth occurs when we consistently set goals just beyond our current comfort zones. How do we determine the ideal balance between manageable challenge and productive discomfort?** 6. **Elite performance is sustained through intense concentration followed by restorative rest. How can we better value recovery as a vital component of our highest achievements?** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- To provide an enjoyable experience for fellow participants, here are three ground rules during discussion events: 1. Step up and step back. (If you feel that you’ve been talking too much, step back to listen more. If you feel that you’ve been relatively quiet, step up to share your perspective or ask a question) 2. Listen to understand, not to respond. 3. Be open-minded and value differences.

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.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
