Firmware Development

**Location**: Tysons-Pimmit Regional Library (Virginia) Conference Room A game development **Working Session** involves 3 key parts: 1. Tell people what you're going to do 2. Actually do stuff 3. Show people what you did That's what we'll be doing for this meeting. We'll briefly tell each other what we're going to do, then work on our projects, then at around 5:30 wrap up to show each other what we did and chat for a bit. You don't have to stay the whole time, so feel free to drop in and out as you have time. All game development skill levels welcome. Whether you're bringing a game you're trying to ship in a month, or you're just planning on following some tutorials or trying out a new tool to improve your skills, use this time to make progress. Working sessions also train you to think about the scope of your work: pick a chunk of work that you can complete in the time that we have. That way you can end the working session with a feeling of accomplishment! **What to bring**: Laptop, Charger, maybe a power strip if you have one handy, any other game development tools you need. Try to download any software you need before the working session. There is Wifi at this location, but it may be slow if you have to download any large files.

**Join a work party to organize the Velocity Bike Co-op warehouse on the first Saturday of each month from 9 a.m. to noon.** Mike Pattisall, Velocity's business manager, will guide volunteers in improving the space where we work. You don't need to be there the whole time. Just come when you can, and wear clothes you don't mind getting dirty with bicycle grease. **Help keep the warehouse organized so there's space to work on bikes on volunteer nights!**

Each week we’ll revisit the core cyberpunk classics — starting with Blade Runner (1982), then Ghost in the Shell (1995), Johnny Mnemonic (1995), Strange Days (1995), The Matrix (1999), eXistenZ (1999), and Blame! (2017).

Date : Feb 7 2026 13:00 - 15:00 EST Title: Symmetry, Topology, and Magnetoelectric Multiferroicity — Ferroelectric 'Tweezers' for Quantum Magnetism in Hexagonal Ferrites Abstract: The scalability of future quantum and spintronic hardware is currently facing a "physical wall": the challenges of excessive heat dissipation and environmental magnetic noise. To overcome these barriers, materials where magnetism can be controlled with high precision and minimal energy will be highly desirable. Magnetoelectric multiferroic hexagonal rare-earth ferrites (h-RFeO3, R: rare earth) have emerged as an important platform for this mission, offering a unique "playground" where symmetry and topology dictate functionality. In this talk, I will provide a comprehensive overview of research progress on these materials over the last decade. We will explore how a specific structural transition—trimerization—breaks symmetry to create a robust state known as improper ferroelectricity as well as weak ferromagnetism. The coupling between the ferroelectric and magnetic orders leads to a "ferroelectric tweezer" effect, where the material's ferroelectric domain spatially anchors and manipulates magnetic domains. Furthermore, we will address the "readout challenge": how to detect the diminutive magnetic moments inherent in these systems. I will show how the non-coplanar spin topology acts as a signal amplifier, enabling high-fidelity readout of magnetic states through spin-transport. By understanding the "solid science" of these complex oxides, we can define the roadmap for a new generation of stable, low-power topological electronics. Biography: Xiaoshan Xu is Susan J.

Title: Biology-Inspired Neural Networks with Multi-Directional Propagation of Values and Distributions Date: Feb 8 2026 10:00 am - Noon EST Summary: While biological axons can propagate in both directions, current ANNs are focused on unidirectional propagation. Also usually they only propagate values, while uncertainty is shown also crucial for making decisions of biological organisms - suggesting to propagate also variance, probability distributions. I will talk about novel KAN-like approach to ANNs repairing these lack by using neurons containing inexpensive local joint distribution model as polynomial, allowing to freely change propagation direction by just switching indexes, also propagate entire probability distributions represented by vectors of moments. Beside backpropagation, it also allows many additional training approaches, like direct estimation, tensor decomposition, and through information bottleneck.

***Arcs*** is a sharp, tactical space opera game, for 2–4 players, set in a dark yet silly universe. Players represent officials from a distant, decaying and neglectful Empire who are now free to vie for dominance whether through battle, gathering scarce resources or diplomatic intrigue. Ready yourself for dramatic twists and turns as you launch into this galactic struggle. A deck of cards in 4 suits with ranks from 1-7 (2-6 for fewer than 4 players) defines the action selection system. These cards are played in a trick-taking adjacent system to select actions, take the initiative and declare Ambitions. The 3 declared Ambitions are what will score in that deal. Timing is everything. Bad hands must be mitigated by careful card play and benefitting from other players' card play. Battles are resolved quickly with the attacker choosing their level of risk. The defenders must be prepared with adequate defensive ships and cards in their tableau.
