Cryptography

For this special session, we’re trying something a little different. Instead of the usual introductory talk, the evening will begin with a short live debate on one of the most pressing and controversial moral questions of our time: **the morality of assisted dying**. Camden Bassett (Veins of London Meetup) and Roger Jones (host of Philosophy Café London) will each take a position and present a brief opening argument, responding to one another in real time. The aim is not to “win” the debate, but to clarify the issues, sharpen the arguments, and open up the discussion for everyone in the room. After that, the emphasis is on discussion and participation. The aim is to create a space where ideas can be explored together, with time for questions, reflection, and open conversation. No prior knowledge is needed — just curiosity and a willingness to think together. **Where:** Downstairs room, Square Pig, Holborn (private room) **NB:** The event begins at 7pm, doors open at 6:50pm. Event ends at 9pm **Format:** 10-minute intro talk → vote on questions → small-group discussions → share insights with the whole room **Discounts:** If cost is a barrier, we want to make the session as accessible as possible. If you are a student, unemployed, or on a low income, please feel free to send me a direct message to get a reduced-price place. **Refunds:** If you are unable to attend and would like a refund, please send me a direct message at least 48 hours before the event. Unfortunately, I’m not able to offer refunds for cancellations made after this point, as it becomes difficult to reallocate places at short notice.

**New members of all ages always welcome!** One day in 399BC in the Athenian Agora, shortly before his trial for impiety, Socrates meet Euthyphro, another citizen involved in a religious suit and their subsequent conversation, whether fact or fiction or a mixture of the two is vividly portrayed by Plato in his short dialogue. Socrates, being prosecuted for his supposed failure to acknowledge the gods, is shown to have more concern for religious matters than his somewhat naïve friend; at the same time, however, Socrates’ probing about the logical inconsistencies in Euthyphro’s views about piety and the gods reveal him as a radical critic of Athenian social and moral values.

**🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 📓 **HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/B6fqS6HGujq8gb3a0kl5pS), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 13:45-14:00 - Arrive, grab your seat, shuffle around if you want to sit at a different table to meet new faces, and do table introductions. This is also when I check people in on the Meetup app. * 14:00-14:05 - Once everyone has been checked in, I give an explanation of Practical Philosophy read the guidelines, introduce the week’s philosophy topic, and share the jump-off points. * 14:05-14:55 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 14:55 onwards - We do a group conclusion of the things we discussed, and then we typically take a photo and go on our way :) If you don't want to be in the group photo, there's no pressure, it's just a way to close out the meeting. We occasionally have an unofficial social so the different groups can mingle afterwards too! **🧧PRICING?** Practical Philosophy Club is FREE to attend, and we operate on donations. If you'd like to donate to support our running costs, that helps keep our group self-sustaining. Donations are 100% voluntary, but your contribution is appreciated! QR codes to donate will be present. Tea’s and coffees and are paid by the individual should they wish to have them. **💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** 🗣 “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * What will we talk about? What's the topic? The topic for the week is shared every week in the Whatsapp group before the session. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/B6fqS6HGujq8gb3a0kl5pS). * Do I need to study or read anything to attend? No preparation is necessary. This isn’t a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it, but it's not required. * Is there a specific philosophy that Practical Philosophy is focused on? The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * Is it mostly men that attend? Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * Can I come alone? Of course you can, we encourage it :) * Can I be late? Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow. * Where do you meet? The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/B6fqS6HGujq8gb3a0kl5pS) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/). 🤝**POLICY** To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
