Debate Night: Free Party "Movement"
The topic of this event has been heavily inspired by [Blast](https://www.blast-info.fr)'s video on the subject matter:
[FREE PARTY : LE CAUCHEMAR OBSESSIONNEL DU GOUVERNEMENT](https://www.youtube.com/watch?v=GSvVvq3KxfI)
The history of free party events dates back to the Thatcher era. In 1987, her government passed legislation that effectively forced many bars and clubs to close at 2 a.m. As a result, groups of people began occupying abandoned factories on the outskirts of cities in order to keep the party going. While some gangs and groups attempted to take over these gatherings for profit, most remained true to the punk and squatter ethos from which they emerged.
A further pushback from the UK government came in 1994 with the Criminal Justice and Public Order Act, which, in a rather absurd manner, prohibited gatherings of more than 10 people listening to music characterized by "a succession of repetitive beats." Many free party groups, such as Spiral Tribe, Bedlam, and DiY Sound System, left the UK and settled in France, where the movement found fertile ground.
These parties can be recognized by their distinctive music and aesthetics. However, they are much more than that. They are organized in a highly horizontal manner, where even the musicians are almost part of the public, and attendees are free to branch out and play their own music with few clear boundaries, not even temporal ones. This creates an atmosphere of intense emotions, spontaneity, and very limited oversight.
People from outside these circles often claim that these gatherings are places of lawlessness, with little respect for private property, where participants seek a state of trance through music, drugs, or both.
Recently, RIPOST, a legislative proposal aimed at cracking down on free parties, passed the Senate, the upper chamber of the French Parliament. It proposes criminalizing the organization of such events, with penalties of up to two years in prison and a €30,000 fine. It would also criminalize participation in these parties, with penalties of up to six months in prison and a €7,500 fine.
While many participants consider these parties to be fully apolitical and simply an escape from the hardships of modern life and the realities they experience, others, including many observers and experts, see a deeply political dimension in these gatherings through their rejection of governmental control and conventional social structures.
One particularly haunting quote, often associated with participants in the movement during the 1990s, captures this sentiment:
*"We are dancing on the ruins of the West."*
How should we, as a society, view such organizations? Could they be regulated in a way that would not backfire? Or are they a litmus test, a canary in the coal mine whose repression signals a drift toward authoritarianism?

This debate will follow a British Parliamentary format with eight debaters split into **four teams of two.**
Participants who wish to speak are highly encouraged to bring a paper and pen. You are welcome to participate even if you have no prior debating experience.
We aim for debates that are respectful, constructive, and welcoming:
* **Respect ideas and people** Listen actively, stay quiet while others speak, and debate arguments, not identities or beliefs.
* **Be concise and civil** Keep questions short and relevant; avoid hostility, hate speech, or discrimination.
* **Respect boundaries and time** No unwanted advances or suggestive behavior; arrive on time to avoid disrupting the debate.
* **Follow moderators** They guide the discussion and ensure fairness.

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
How to Take Control of YOUR Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind.
Find out what the reactive mind is, and in the process find yourself.
Here is the secret of being positive and free:
Thinking positively is not enough.
You also have to get rid of the negative thinking.
Your mind is like a garden.
You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden.
A positive thought is like a flower in your mental garden, and a negative thought is like a weed.
You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there.
So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out!
The Meetup event will be led by a consultant who had helped many people live happier in 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 Dianetics & Scientology life improvement center.

IxDA Chat n Pancakes
You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday.
But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to.
Thanks to the team at Nationwide of supporting the group.
Columbus Arduino Raspberry Pi Enthusiasts (CARPE) (Check Location)
