Description: Join us for an enlightening lecture that delves into the intricate web of the past and its potential to cast a long shadow over our present lives. In this thought-provoking session, we will explore the profound ways in which the past can negatively impact our well-being, choices, and personal growth. Throughout history, human lives have been shaped by a multitude of experiences, both positive and negative. These experiences accumulate, leaving imprints on our memories and shaping our beliefs, attitudes, and behaviors. While the past holds valuable lessons and cherished memories, it can also harbor unresolved conflicts, traumas, and limitations that subtly influence our present reality. During this lecture, we will navigate the labyrinth of psychological and emotional baggage that may accumulate over time, inhibiting our personal development and impeding our ability to lead fulfilling lives. By examining the effects of the past on various aspects of our existence, we will gain a deeper understanding of how it can manifest in detrimental ways. Through engaging discussions, case studies, and real-life examples, we will explore the following topics: 1. The Power of Unresolved Trauma: We will delve into the profound impact of unresolved traumatic experiences and how they can subtly shape our thoughts, emotions, and behaviors. By shedding light on the intricate mechanisms behind these effects, we can begin to dismantle their hold on our lives. 2. Inherited Baggage: Examining the intergenerational transmission of pain, beliefs, and patterns of behavior, we will explore how our ancestors' experiences can unconsciously influence our lives. By recognizing and addressing this inherited baggage, we can break free from destructive cycles and chart our own path. 3. Limiting Beliefs and Self-Sabotage: Uncovering the deeply ingrained beliefs and narratives that stem from past experiences, we will explore how they can become self-fulfilling prophecies, stifling our potential and sabotaging our aspirations. By challenging these beliefs, we can reclaim our personal power and reshape our narratives. 4. Breaking Free: Strategies for Healing and Transformation: This segment will offer practical tools and techniques for healing past wounds, releasing emotional burdens, and cultivating resilience. We will explore approaches such as therapy, mindfulness, self-reflection, and forgiveness to facilitate the process of letting go and embracing personal growth. By the end of this lecture, attendees will gain a deeper understanding of the profound influence the past can exert on their lives and how to break free from its negative impact. Armed with newfound knowledge and practical insights, they will be empowered to embark on a transformative journey towards self-discovery, healing, and the creation of a brighter future. Note: This lecture is open to all individuals seeking personal growth and a deeper understanding of the psychological and emotional factors that shape their lives. No prior knowledge or experience is required, only an open mind and a willingness to explore the depths of the past.

The monthly indie pub night is relaxing social with other indie game devs in London. Usually it's quite well attended and all kinds of cool indies show up. Also, silly party games are known to be played. Here’s the website: http://www.londonindies.co.uk

April Edition ✨✨! We will be at Kraken Tech (Octopus Energy Group), London office! (in-person only event, no streaming) **Talks:** **Digitising Historical Caving Data with Django** - *Andrew Northall* Building an automated pipeline with Django which can extract, structure and publish 2,700+ historical printed reports from scanned PDF copies. *Andrew Northall* is a Python & Django specialist who maintains several open source Django projects/services for the caving and amateur radio communities. **llms.txt for Django: what works** - *Thibaud Colas* The llms.txt format is an emerging standard to structure information for Large Language Models. It’s a desirable addition to the docs of Python packages. Let’s review how to adopt it! We’ll discuss the fundamentals of the format and its benefits as a user of the docs, and as a maintainer. How to produce and consume those files across different tools (Sphinx, mkdocs, Django). How to optimize them for different LLMs with an eval suite. Tools and techniques you should be able to reuse through other engineering tasks with LLMs. *Thibaud Colas* works at Torchbox as developer, core contributor to the Wagtail CMS build on Django. **Want to share your Django or Python knowledge?** We’d love to feature your talk!

As always, there will be free food and drinks, generously provided by our host, Man Group. **Main Talks** 1. **[Nicoleta Lazar](https://www.linkedin.com/in/nicoleta-lazar-921a6864/) Query federation in modern OLAP databases** As analytics ecosystems grow more diverse, organisations increasingly need to query data across warehouses, data lakes, and operational systems without excessive data movement or duplication. **Query federation** has become essential by enabling unified SQL access and intelligent predicate pushdown into heterogeneous sources. This talk introduces the core principles of federation and why it matters for modern OLAP workloads. Using StarRocks as a model system, we highlight its vectorised execution engine, native connectors, and deep Apache Iceberg integration that together deliver high-performance lakehouse querying. 2. [Ben Guerin](https://www.linkedin.com/in/bjhguerin/) **How I Learned to Stop Worrying and Let Claude Code Write the Python [the story of [ismypubfucked.com](http://ismypubfucked.com/ "http://ismypubfucked.com")]** 43,000 pubs. Official VOA data. One question. [ismypubfucked.com](http://ismypubfucked.com/ "http://ismypubfucked.com") got 400k visits in two weeks and wall-to-wall media coverage: from the Mirror to the Telegraph to City AM. I'm not a Python developer. I used Claude Code to wrangle government spreadsheets, match them to OpenStreetMap, and ship a working site. All in less than 6 hours from initial idea to a live website. The AI wrote the Python, I just knew what story the data could tell. This talk covers what happens when tools like Claude Code unlock Python for people who think in narratives rather than syntax, and what a decade of building viral campaigns has taught me about making people actually give a shit about spreadsheets. **Lightning Talks** 1. **TBC** 2. **TBC** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Logistics** Doors open at **6.30 pm** (get there early as you'll need to sign in with building security).

We're limited by building security on the number of attendees, so please free up your place for your fellow community members. If you want me to trim lightning talks down to two or shorten any abstracts, say which ones.

Elixir London Meetup; February 2026 edition. All are welcome. **Session 1: Anton Borisov - Distilling Kafka's Binary Protocol into Elixir** We'll trace a produce request to show what any Kafka client has to get right. In the BEAM ecosystem, erlkaf wraps librdkafka, brod implements the protocol in Erlang, and [kafka_ex](https://hex.pm/packages/kafka_ex) goes pure Elixir. Kafka_ex's approach is to generate serializers at compile time from Kafka's own schema definitions: plain structs, pattern matching, structural boilerplate isolated from the logic you actually think about. That design is what let us jump two major versions ahead and adapt to significant protocol changes. Let's dig into the idea, the code, and the tradeoffs. **Session 2: Evadne Wu** **\- JavaScript Execution Strategies in Elixir\-based Agent Frameworks** We'll look at integration points between elixir agents (in the AI fashion) and JavaScript execution, and all the foot guns involved. *The event is kindly sponsored by* [Fresha](https://www.fresha.com). **Time** Doors open at 18, start at 18.30. **Venue** Fresha The Bower, 207-211, Old St, Tower, London EC1V 9NR **Refreshments** Food and drinks will be provisioned on the day. **IMPORTANT**: **If you wish to take photos and post online during the event, please notify organisers first, so that attendees can opt-out from being in photos.**

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
