The New Frontier of Bitcoin Mining at PubKey DC
Bitcoin mining today looks very different from what it was a decade ago. What began largely as a hardware race has evolved into a complex global industry shaped by energy markets, infrastructure development, and new demands on data centers. Companies that adapt to this new reality don’t just survive. They position themselves to lead the next phase of the industry.
👉 [RSVP on Luma](https://luma.com/cmlndtin)
In this panel, executives from publicly traded mining companies will discuss how their strategies reflect this new frontier. From hardware innovation and home mining to heat reuse, large-scale energy infrastructure, and the growing intersection with AI and high-performance computing. The conversation will explore how the industry has changed, where it is headed, and why these companies remain committed to building in Bitcoin.
**Guest Speakers**
* James Cheng (CFO, Canaan Inc.): A seasoned finance leader with over 20 years of experience at Fortune 500 companies, James oversees the financial strategy for a major NASDAQ-listed hardware pioneer, focusing on investor relations and debt/equity financing.
* Darcy Daubaras (CFO, HIVE Digital Technologies): A strategic financial expert and Corporate Director, Darcy leads global growth for HIVE, specializing in public company regulatory reporting and the intersection of crypto mining with high-performance computing.
* Elizabeth Frei Duchek (Government Relations, Bitdeer): With over 15 years of experience in government affairs and policy analysis, Elizabeth leads government relations for Bitdeer (NASDAQ: BTDR). Her background in appropriations and public policy brings a critical perspective to how regulation, infrastructure, and energy policy intersect with the future of Bitcoin mining.

"The Optimist's Daughter" by Eudora Welty
We've never read Eudora Welty here, so we're going to discuss her best-known work, the Pulitzer Prize-winning "The Optimist's Daughter." This short novel, which began as a story in the New Yorker, is about a woman who travels to New Orleans to take care of her father after surgery. I've been meaning to read Welty for years, so I'm happy we're doing this now.
Python Packaging 101: From Code to Installable Package
Have you written Python code you’re proud of and wondered how to turn it into a proper, installable package? Join us for a hands-on, in-person workshop on **Python packaging**.
In this session, we’ll walk through the modern Python packaging workflow — from structuring your project to building, installing, and publishing your own package. You’ll leave with a better understanding of tools like `pyproject.toml`, build backends, and how packaging fits into real-world development.
This is a practical workshop, so come ready to code. We’ll work step by step together
### What we’ll cover
* Recommended project structure for Python packages
* Understanding `pyproject.toml`
* Building your package locally
* Installing and testing your package
* Publishing a package to Test PyPI
Whether you’re contributing to open source, building internal tools at work, or preparing your own library for distribution, understanding packaging is an essential Python skill.
***
### Recommended Experience
This is an intermediate level workshop, to get the most out of this tutorial, you should be comfortable:
* Writing Python code
* Using functions
* Working with Python environments (e.g., virtual environments)
This is not a beginner Python session, but you don’t need prior experience with packaging.
***
**This event is primarily intended to create an empowering and supportive space for women and non-binary individuals to find community, learn new technical concepts, and expand their software development skills. We welcome allies, and we ask that you remain mindful of the event’s focus in creating an inclusive environment where women and non-binary participants can connect and fully express themselves. Thank you for your understanding and support.**
***
### Schedule
5:30–6:00pm – Networking and getting to know each other
6:00–8:00pm – Hands-on Packaging Workshop
8:00:–8:15pm – Wrap-up and Q&A
***

* Laptop — this is a hands-on event
* GitHub account
* Create a free GitHub account if you don’t already have one: [https://github.com/](https://github.com/)
* Test PyPI account (we’ll use this to practice publishing packages)
* Create a free account on Test PyPI: [https://test.pypi.org/account/register/](https://test.pypi.org/account/register/)

Disaster+Travel+Wilderness First Aid (In-Person) Certification Course
Hands-on learn how to save life & limb, when mired in the wilderness of an urban disaster zone, travel or rural area far from hospital, or natural area miles from an access point, during the critical minutes or hours before ambulance arrival. Come away with actual do-it-yourself care-giving skill and confidence, and 2-year SOLO certification. Counts as WFR Recertification, too. No prerequisites.
YOUR SPOT IS NOT RESERVED UNTIL YOU'VE COMPLETELY REGISTERED AT WWW.SOLOWFA.COM \***Spaces are limited. REGISTER: www.solowfa.com or 434.326.4697**
Can't make these dates? Check out more course locations and dates on our website.
WHO: Open to the general public, adults & teens with solid attention spans. Know your loved ones are safe wherever they are.
WHY: Mired in a disaster zone, travel or rural area far from a hospital, or natural area miles from an access point ... accidents, destructive weather, and terrorism happen, and all-too-often members of a group are not capable of dealing with the emergency. This leads to improper care of the patient, and endangers the entire group. Many recreational accidents are preventable, and improper care of trauma can compound even simple injuries. Very few first aid programs actually address the issues of providing emergency care in a setting where 911 is overwhelmed or not immediately reachable. In this course, classroom instruction and Q&A are interwoven with practical work and problem-solving exercises. Hands-on experience - a most powerful learning tool - during scenarios comprise \~50% of class.
TIMING: This is a 2-day class, Saturday and Sunday, 8:00am -7pm each day.
Fee: $295 (Earlybird)

Take a Hike! @ Turkey Run (shorter version)

The trail includes shallow stream crossings, adding some fun technical elements along the way. We’ll take regular breaks to regroup, hydrate, and enjoy the scenery. **Hiking shoes are a must -** the trail is slippery, and the extra grip of hiking shoes is essential for safety. Also, don’t forget your **hiking poles**; they’ll be helpful at the stream crossings.
After the hike, join us for a social gathering at **Chiang Mai Thai Cookhouse (6828 Old Dominion Dr., McLean)** to unwind, grab a bite, and enjoy time with fellow hikers.

A steady, comfortable pace that’s manageable for most hikers with a reasonable fitness level. Breaks are regular but not overly frequent, allowing for a balanced experience of exercise and enjoyment.
**Parking**
Park in Turkey Run’s **Lot C-1,** where there's plenty of room for all. Grab a spot, lace up, and get ready to hit the trail!

Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!
Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life.
Mission: grow, support, and provide community for atheists in Central Ohio.
Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision.

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
