Philosophy of Friendship: What are the bases of "friendship"?
As you may or may not know--I didn't until late last year--Aristotle wrote extensively on "friendship" in the Nicomachean Ethics. After 69 years the concept of friendship still creates questions and uncertainty. I had close friends in high school and for a few years after high school but our interests diverged and people moved all over the country so it was hard to maintain connections.
* So if I/you haven't talked with a friend for several years, are you still friends? Are we friends who meet at Drunken Philosophy or Omnipresent Atheists?
* Can you be friends with someone with whom you have virulently divergent political views? Sartre and Camus could not.
* Aristotle regarded friendship as essential to a good life, not merely an added "bonus." Do you agree?
* In the Nicomachean Ethics (Books VIII and IX), he claims that wealth and power are meaningless without friends. Trump has wealth and power but seems to have no real friends, but wealth and power seem meaningful to him in perverted ways. Can you have meaning in your life without friends?
* Do men and women view and maintain friendships in different ways?
* Aristotle categorizes friendship into three types, based on what forms the bond:
* **Utility**: Based on mutual benefit, but this type is fragile and ends when the usefulness ceases.
* **Pleasure**: Based on shared enjoyment (e.g., humor, hobbies). Common among youth but fades as interests change.
* **Virtue (The "Complete" Friendship)**: Based on mutual respect for each other's character and goodness. You wish good for the other for their sake, not yours.
* **Key Principles of "True" (Virtuous) Friendship:**
* **Permanence**: Virtuous friendships last a lifetime whereas those based on utility and pleasure are fleeting.
* **Reciprocity**: Requires mutual goodwill; secret or unreciprocated affection does not qualify.
* **The "Second Self"**: A true friend is "another self"âtheir virtue helps you understand and improve yourself.
* **Time and Intimacy**: Deep ("complete") friendships are few, built on time and shared experiences.
* **Self-Love and Friendship:**
* Good friendship starts with being a friend to yourself.
* They distinguish shallow egoism (chasing honors) from real self-love (pursuing virtue).
* A virtuous personâs pleasant self-company allows them to be a stable, good friend to others.
* Aristotle argues that one's social circle ultimately reflects one's characterâa view with striking relevance today. Well--the Drunken Philosophy social circle certainly reflects good character!

Shut Up & Write!⢠Easton Town Center
We'll meet at The Capital One CafĂŠ, 167 Easton Town Center, Space A-103. This is in the main mall where the Microsoft store used to be, on your left if you're standing at the bottom of the AMC Theater escalator.
Join us on Saturday for an hour of uninterrupted wordmaking!
⢠What we'll do
Join us for an hour of writing! Weâve discovered that itâs strikingly helpful to write with other writers. See if itâs true for you at 10AM on Saturday mornings.
Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done.
SCHEDULE:
10:00 - SESSION 1: quick intros.
10:10 - timer starts: write for 1 hour.
11:10 - chat / take off / keep writing.
OPTIONAL SOCIALIZING happens at 11A-11:30ish. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing.
BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. (Iâll be the person with the Shut Up & Write! sign.) If you were on time, please be willing to make room for the friendly latecomer.
Happy writing and I look forward to seeing you!
⢠What to bring
Whatever you need to be able to write!
Bring earbuds/earplugs if you want to block noise or the occasional conversation by other patrons. Electrical outlets are limited, so charge your devices before whenever possible.
See you at The CafĂŠ on Saturday!
Morning people unite!! đ¤ â + đŹ @ Good Cafe
Early-bird coffee and conversation at [Good Cafe](https://goodcafeeaston.com/)!

Spec-Driven Development with GitHub Spec-Kit - Barret Blake
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
*Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation*
Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, weâll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifactsâliving documents that drive architecture, implementation, and verification.
Youâll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. Weâll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, weâll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written.
This talk will cover:
--What spec-driven development is (and what it isnât)
--How GitHub Spec-Kit fits into modern developer workflows
--Using specs to align product, engineering, and AI-assisted development
--Real-world examples of turning specs into implementations with confidence
Whether youâre building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects.

### Much Ado About Nullable - C# Nullable Reference Types Explained
In 2019 (C# 8.0) Microsoft introduced a feature that has generated a lot of confusion, debate and outright dissent. I'm talking about Nullable Reference Types. In this presentation, I we dig into this feature, explore why it exists, what problem it tries to solve, how it works, and how people have critiqued it, so that you as a programmer can decide if and how you want to use it.
