Cryptography

This June we're at FundApps offices in HYLO, Bunhill Row. Chris Simon's back in town, and will be joining us to talk about streams and queues; plus Tiago Sousa from SteelEye will be talking about the work they're doing around using AI in comms surveillance. Our hosts at FundApps will be providing drinks and snacks, and there will be plenty of time to chat beforehand and in the pub afterwards. **Chris Simon: It's like 10,000 streams when what you need is a queue** *🎶🎵 A new dev team adopted E-D-A* *Got head of line blocking, on their very first day* *Isn't it ironic, don't you think 🎶🎵* The last few years have seen widespread adoption of Event-Driven Architecture, supported by DDD practices such as event storming. But what does that orange sticky note become when we start implementing our design? Common implementation choices include event sourcing, streaming platforms like Kafka and queuing systems like RabbitMQ. Unfortunately not every orange sticky note has the same operational needs, and many teams remain confused about the differences between these options, resulting in the selection of the wrong paradigm for their needs. This can lead to unnecessary complexity & operational challenges such as head of line blocking, dropped messages, challenges dealing with failed messages, difficulty with adaptive scaling and inadvertently increasing coupling between services. In this talk we'll bring that orange sticky note into the runtime of our system. We’ll start with a deep dive into the similarities and differences between event streaming platforms such as Kafka and queueing systems such as RabbitMq, Azure Service Bus & AWS SNS/SQS. We’ll then look at ways to assess your orange sticky notes to work out which messaging and persistence paradigms suit each one, helping you build more resilient, scalable and loosely coupled event-driven architectures. **Tiago Sousa: AI in Comms Surveillance** In this talk, Tiago shares what it's actually like to build AI for communications surveillance at SteelEye. Financial firms are required to monitor and flag communications for compliance, but making AI work reliably in that context is harder than it sounds. He'll walk through real examples from the trenches: what worked, what didn't, and what he'd do differently. **Tiago Sousa** is a Staff Data Engineer and AI Lead at SteelEye - a platform that helps financial firms monitor and flag communications and trades to stay compliant with regulations. He's spent the last five years building the data and AI systems that make that work. Before that, he did research in bioinformatics, which means he came into fintech from an unusual angle and has the scars to prove it. He's based in Braga, Portugal.

The first session of Menus of Conversation in 2026 will be on Thursday 25th June from 7pm onwards. We will be in the bar section on the ground floor - when you arrive, if you are trying to figure out where exactly we are in the venue, just keep an eye out for the people enjoying themselves! I have started drawing event posters and will draw another poster for next month. I would love it if you would be so kind as to check them out now on Instagram at https://www.instagram.com/menusofconversation/ **Price** The event is a pay what you can event. You can tip whatever you think has been a fair price for your event experience. The suggested tip is a minimum of £4-5. You can pay with cash or card on the night. PS, if you've been before, please take a minute to complete my survey! https://www.surveymonkey.com/r/NZSZD88 Follow us on Instagram: https://www.instagram.com/menusofconversation/ and Facebook: https://www.facebook.com/New-Conversation-104308482323373 **Event Description** This is a social event where people have the chance to have a one-to-one conversation with someone they may or may not have met before using a 'conversation menu' (picture attached). A conversation menu is a list of pre-written conversation starter questions which participants use to have a conversation by discussing the different questions. The questions are generally about some of life's big questions and lead to some interesting conversations about important, fundamental topics which we certainly don't get the opportunity to discuss every day. Some might consider our events to be 'small-talk free zones'. The event brings people together and invites people to discuss topics and answer questions they don't get to discuss on a daily basis, especially with people they don't know. The idea is that the more we talk about topics we don't normally talk about, to people we don't normally talk to in our habitual social circles, the more opportunities, connections and possibilities we create for ourselves. If we discuss different topics with different people, then we achieve different results. Testimonials for the events held so far include: 'For me it was a brilliant success and hopefully it will be for many others. It is a simple idea simply executed, asking people to pair up and discuss a number of questions on a list. And it works! Although I vaguely knew my partner, the questions allowed us time to touch on areas that I think we would have been otherwise unlikely to ever discuss e.g. which parts of your life have been a waste of time?' 'Surprisingly good and thoroughly worthwhile. Suggested questions excellent.' ‘I can heartily recommend coming along to a conversation event. The questions were really thought provoking and led to some fascinating conversations. I really enjoyed the evening and I came away with feeling I’d learned a lot from my conversation partner.” ‘I thought it was a very interesting meeting. I thought it was interesting to try to answer personal questions and listen to the other person.’

Connecting people into Philosophy. All welcome. No previous philosophical experience needed. **What it is** Philosophy in the Park is a fun and friendly space for people to come together and have discussions that get deep. It’s a safe space where active creative thinking is encouraged and enjoyed, and where everyone can explore abstract concepts in a way that combines both sincerity and playfulness. Where the most important question is always - what do you think? **What is Philosophy?** Philosophy is about analysing concepts. It's thinking about thinking. It's not about empiricism or the physical world (eg Science and statistics). It's about abstractions, concepts and ideas (eg Identity, Morality, Mind and Truth). **How Philosophy in the Park Works** * Each hour begins with a group vote on which questions to discuss. You can vote for more than one question if you'd like. * We then break out into groups, each focusing on one of the chosen questions. The question is just a starting point and it's cool if you go on tangents and end up talking about different things. You're welcome to join in and participate or if you'd prefer to sit back and enjoy the conversation, that’s also welcome. * After an hour we regroup, take a quick break and then repeat all over again. So across the 3 hours, we’ll break out 3 times. **Where it is** We meet at Baroness Burdett Coutts Drinking Fountain in Victoria Park (East Park). It is marked down as "13" on the official maps found in the park. Please feel free to bring snacks and drinks with you if you want. After the event finishes most people stay and hang out. There’s a local supermarket to get drinks and snacks, or bring your own. You are very welcome to join us. **Guidelines** In order to make the conversations as fun, interesting and productive as possible please follow these simple guidelines: 1. Keep it Philosophical (No Science, no History, no Sociology, no Evolutionary Psychology, no contestable facts, personal anecdotes etc). 2. Think for Yourself (No phones, no looking up definitions, no name dropping Philosophers / books you've read). 3. Tangents are Cool (Don't worry too much if the subject drifts and you don't answer the question). 4. Keep it Succinct (Like this). 5. Be Excellent to Each Other (But of course). Please remember: It's not about debating and trying to win - it's about listening to people and working collaboratively to increase our collective understanding. **Community** Follow us on instagram: [https://www.instagram.com/londonphilosophycollective/](https://www.instagram.com/londonphilosophycollective/) We have a WhatsApp group if you'd like to continue these conversations between meetings. To join the Philosophy in the Park WhatsApp Group please click here: [https://chat.whatsapp.com/CdFaxJHbeOw9UOfuk7spiK](https://chat.whatsapp.com/CdFaxJHbeOw9UOfuk7spiK) In order to stop spam bots this will take you to a Waiting Room.

Most people think of Friedrich Nietzsche as a philosopher of pessimism. They think of nihilism, the death of God, the collapse of values, and a thinker who stared into the abyss. But what if one of the most common interpretations of Nietzsche is fundamentally wrong? In this lecture, Dr. Nash Jocic argues that Nietzsche's first book, *The Birth of Tragedy*, is not a pessimistic work at all. On the contrary, it represents one of the most powerful affirmations of life in the history of philosophy. Drawing on Nietzsche's engagement with Schopenhauer, Greek tragedy, suffering, art, and the problem of meaning, we will explore why Nietzsche believed that the existence of suffering does not make life meaningless. Instead, Nietzsche's central question was: How can we affirm life despite suffering? Topics include: • Nietzsche and Schopenhauer • Greek Tragedy and the Meaning of Suffering • Why Most Interpretations Get Nietzsche Wrong • Nihilism and Meaninglessness • Art as the Justification of Life • Why The Birth of Tragedy Is Ultimately an Optimistic Book This lecture is suitable for both newcomers and those already familiar with Nietzsche's work. Speaker: Dr. Nash Jocic, PhD Author, lecturer, and founder of Philosophy Matters UK.

**🏛️ 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: * 14:00-14.15 - People arrive and chat, get to know each other before the ‘official' start. * 14:15-14:20 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 14:20-15:20 - 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. * 15:20-15:30 - 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 of the conversation. * 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. Practical Philosophy reserves the right to enforce this policy at its discretion to maintain a safe and respectful environment. **PRACTICAL PHILOSOPHY - Making Philosophy Available To All.** ✨ Practical Philosophy hosts weekly, in-person meetups in 25+ countries, including Canada, Spain, Japan, Mexico and many more! 🗺️ \*\*\* Join our [Whatsapp group](https://chat.whatsapp.com/B6fqS6HGujq8gb3a0kl5pS) 👈 Follow us on [Instagram](https://www.instagram.com/practicalphilosophyclub/?hl=en) 👈 Our [website](https://www.practicalphilosophy.club) 👈
