Join us for an evening of networking and insightful discussions at our Cigars & Startups Networking Night, hosted by Cigars and Startups DC. Whether you're a seasoned entrepreneur, a startup enthusiast, or a tech aficionado, this event is the perfect opportunity to connect with like-minded individuals. We'll have premium cigars, drinks and talk about the exciting topics of entrepreneurship, securing venture capital funding, and the intersection of technology startups and the cigar industry. Sip on fine drinks, enjoy premium cigars, and engage in lively conversations with fellow guests who share your passion for entrepreneurship and innovation. Whether you're looking to expand your professional network, seek investment opportunities, or simply unwind after a long day, this event promises to offer a unique blend of business insights and leisure. Don't miss out on this exclusive chance to mingle with the brightest minds in the startup ecosystem while enjoying the finer things in life. Thanks to our sponsors @Hunter from Next.Law, @Richard from Ashira Finanical and @Andrew from Zccounting.com Note: Because my company (Zccounting) is a bookkeeping and accounting firm, not a licensed tobacco dealer I will not be selling cigars and your ticket only includes "entry" to the VIP lounge and event, however, I'm super generous and will share as many cigars as you can smoke at the event from my personal collection for no fee whatsoever!

Come the whole time or if you just spend 30 minutes. All are welcome. You are welcome and encouraged to bring your own coloring supplies but, if you don't have any, I will have plenty and am happy to share! (coloring books, colored pencils, and markers). Part of the mission of this group is to provide us an opportunity to check out AND SUPPORT local businesses. So, please don't bring any outside food/drinks and, while purchasing something isn't at all a REQUIREMENT to participate in the event, I do strongly encourage you to try something from the vendor :) I look forward to seeing and meeting you there! ***\*\*DISCLAIMER*\*\*** Photos may be taken during the event to be shared here on Meetup so feel free to let me know if you'd like to be excluded from them.

Join us for our first meetup! We will have a discussion on Fiat vs Bitcoin, a little bit of learning and discussions that are important to the group. This a social group so bring your questions and curiosity, prepared to listen and share. Too often, women are left out of the conversation while they prepare to live longer, care for more people and are the heart of any community. Wouldn't it be great if we could be more educated on ways to beat inflation, have more choices, and be prepared for the changes to come? Please bring your questions, so that we can plan topics for future meet-ups.

Pitch your idea, get feedback, give feedback, meet with a mentor and most importantly, take action. Come to the meetup with a specific issue you are stuck with. **10:30 am Introductions:** 2-minute pitches tell us who you are? What you're working on? and what you need help with? **11:00 am Problem Solving:** Let's figure out how we can help, and what action you can take today to move forward. **12:00 pm** Open Networking: Keep the discussion going and connect with other attendees. Bring yourself, notebooks, laptops and anything else you need to pitch your idea and get work done. Interested in joining the Studio? [APPLY NOW](https://unstucklabs.com)

Weekly Draft night in NW. We currently meet up at Franklin Hall near 14th and Florida. U Street Metro is the closest stop. I'll have packs but feel free to bring packs if you have them. Entry is $17 (you can bring Play Booster packs to lower the cost by $3.50). If it is a special set, it will be more.

Title : Blockchain in the Quantum Era: Risks, Opportunities, and the Future of Secure Decentralized Systems Time: Feb 1 2026 8:30 am - 10:30 am EST Abstract: As quantum computing advances, the security foundations of blockchain systems face significant transformation. Blockchain relies heavily on classical cryptographic algorithms to ensure trust, authenticity, and immutability. However, quantum computing introduces new computational capabilities that could challenge these cryptographic primitives. This talk explores the risks posed by quantum technologies to existing blockchain systems, examines emerging post-quantum cryptographic standards, and highlights new opportunities for building more secure, scalable, and efficient decentralized infrastructures. Attendees will gain a clear understanding of how blockchain can evolve in the quantum era and what steps are required to prepare for the future of secure digital ecosystems.

Title: Geometric Machine Learning with Symmetries and Graphs: Applications in Molecular Problems Date: Jan 31 2026 Noon - 14:00 EST Abstract: For geometric problems, symmetry equivariant machine learning has emerged as the modus operandi. In physics, symmetry is treated as the north star, the guiding principle for problem characterization and method optimization. Geometric features are inherently compatible with continuous Lie groups (and therefore symmetries), leading to continuous parametrization and successful training methodologies. The general mapping of a classical embedding and a quantum mechanical embedding will be discussed in terms of group theoretical concepts. In the context of embeddings, graph embedding is also a powerful method for machine learning problems taking better care of inter-relations among nodal variables. Classical and quantum neural networks with different subsets of the concepts mentioned will be defined and learning attempted with. The dataset under study is geometric molecular data (from quantum mechanical models) with varying geometric complexity. Performance comparison will include accuracy metrics, generalizability metrics, and.general remarks about expressivity.

After his freshman year of college, he launched his first startup, Redistricter, which took off far faster than expected. He left school and moved to New York to pursue it full-time. ​A year later, he created *Subway Builder*, a hyper-realistic game that lets players design subway systems from scratch while navigating real-world constraints and costs. The game simulates millions of commuters using Census and Redistricter data, powered by the same pathfinding algorithms people rely on to get to work. Your job is to design a route network that gets the most people to their destination as fast as possible. — **Greg Feliu** is a data engineer and analyst focused on transportation analytics, with projects ranging from modeling subway–bus transfers to clustering NYC subway stations by ridership. Drawing on public ridership data and GTFS schedules, he builds minimal-assumption models to estimate ridership on each subway line, combining data modeling with subject-matter expertise to reveal how New Yorkers move through the system with *The Busiest Subway Lines in NYC, Ranked*. **[Please sign up on the Luma event for building access!](https://luma.com/my43kl57?tk=2BGBsd)** **[Follow us on Luma](https://luma.com/transittechies) to continue receiving updates** The event will be held at 370 Jay Street, Brooklyn, NY in Room 1201.
