Elixir London Meetup; February 2026 edition. All are welcome. **Session 1: Bryan Hunt - Faria Data Platform: Building a data platform in Elixir** How to build an ETL pipeline using Amazon Athena, and Elixir: techniques, tools, UX, lessons learned. **Session 2: Christoph Beck** **\- Structured Generation and Logits Processing with Elixir** Ever tried to get a poem from an LLM doesn't contain the letter \`e\`? Large Language Models are kind of amazing and surprisingly unreliable at the same time. Using Elixir's Bumblebee and open source LLMs, you can get much better control over the generation. We introduce you to logits processing, and how it can be used to achieve what ChatGPT can not accomplish. *The event is kindly sponsored by* [Verna](https://verna.earth). **Time** Doors open at 18, start at 18.30. **Venue** Geovation F4, Sutton Yard, 65 Goswell Rd., London EC1V 7EN **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.**

Join me for a fun Drama class every Wednesday evening from 6:30 pm- 8:30pm at the Omnibus Theatre in Clapham Common. Acting helps with confidence and awareness. In a fun and relaxed atmosphere, you will meet new people and learn all about Acting. No experience is needed. We'll do relaxation exercises, games, improvisations, storytelling, and a bit later on we'll start working on character and text. The year ends with an exciting Showcase where friends and family come and see how all your hard work has paid off :) £10 pounds for the trial class to be paid before or after class. Different payment options if you decide to join. In order to reserve a place, please contact me at catherine@thebrightdaycompany.net.

## Details Welcome to the DevSecOps London Gathering February Event on Wednesday 19 Feb in collaboration with London DevOps! We bring you two amazing talks, as well as the usual conversations, pizza and beer! 📍 **Hosted at Autogen AI, Pentonville Road, London** 📅 **Wednesday, 19 February** 🕕 **6:00–8:00 PM** ## Talk 1 **Abstract:** Concrete CMS, a popular open-source content management system, contains a critical flaw in its file upload functionality that can be exploited in two distinct ways. This talk demonstrates how a single upload can lead to a Server-Side Request Forgery (SSRF), allowing access to internal cloud resources, and a double race condition that enables Remote Code Execution (RCE) via a malicious backdoor. We’ll walk through the exploitation process, show how existing protections can be bypassed, and highlight practical steps to secure file upload mechanisms in real-world applications. ## Talk 2 **Abstract** Treat authentication as a production-critical system with its own failure modes and operational risks. In this talk, I break down real-world auth incidents involving JWKS rotation errors, refresh token storms, clock drift, and session store outages. I show how to define SLIs and SLOs that measure user impact and how to build monitoring and alerting that expose real reliability problems. I demonstrate practical guardrails such as token caching, exponential backoff with jitter, circuit breakers, and feature-flagged degraded modes. Finally, I walk through an incident runbook that helps teams diagnose, mitigate, and recover from authentication failures safely and quickly.

Join us for fun drama games and improv. No experience required. Book here or www.actorverse.co.uk

We're hosting our first meetup of 2026 in collaboration with our friends from **DevSecOps London Gathering**. We'll be generously hosted at the AutogenAI offices near King's Cross, and we'll feature two talks that should be of interest to both audiences. **6:00pm - Arrival** **6:45pm - Introductions** **7:00pm - The Talks** **Concrete Evidence: Two Races, One RCE** - [Adrian Tiron](https://www.linkedin.com/in/tironadrian/) Concrete CMS, a popular open-source content management system, contains a critical flaw in its file upload functionality that can be exploited in two distinct ways. This talk demonstrates how a single upload can lead to a Server-Side Request Forgery (SSRF), allowing access to internal cloud resources, and a double race condition that enables Remote Code Execution (RCE) via a malicious backdoor. We’ll walk through the exploitation process, show how existing protections can be bypassed, and highlight practical steps to secure file upload mechanisms in real-world applications. Adrian is the Co-Founder and Principal Pentester/Red Teamer at Fortbridge, bringing over 20 years of hands-on experience in cybersecurity. Adrian is known for delivering highly technical, practical content drawn from real-world assessments, and is passionate about pushing the boundaries of modern application security. **Keeping login from taking down your product with an SRE approach to auth –** [Viola Lykova](https://www.linkedin.com/in/violaly/) Treat authentication as a production-critical system with its own failure modes and operational risks. In this talk, I break down real-world auth incidents involving JWKS rotation errors, refresh token storms, clock drift, and session store outages. I show how to define SLIs and SLOs that measure user impact and how to build monitoring and alerting that expose real reliability problems. I demonstrate practical guardrails such as token caching, exponential backoff with jitter, circuit breakers, and feature-flagged degraded modes. Finally, I walk through an incident runbook that helps teams diagnose, mitigate, and recover from authentication failures safely and quickly. Viola is a Senior Software Engineer in fintech with an SRE mindset, focused on authentication as a production system. I care about reliability, incident patterns, and the kind of testing that still holds up when traffic spikes, dependencies misbehave, or keys rotate at the worst possible time. Viola speaks on practical auth topics across security and reliability. **Participate in a future Meetup** If you'd like to speak at a future meetup, or if you are able to host or sponsor the event, please fill in this [form](https://docs.google.com/forms/d/1FYGHEWTeBb5vVztGGg2YoUJmKR03o9mZaFIghf6vjzo/viewform?edit_requested=true) and we'll get back to you.

We are excited to partner with Coder for a special edition of our AI Meetup in February, focusing on AI governance and compliance for developers. AI is already part of how developers work: Coding assistants. Autonomous agents. Background tasks. PR reviews. But in most companies, AI usage is either completely ungoverned or quietly blocked. This meetup is for developers who want to understand what AI governance actually means in practice, without turning their workflow into a compliance nightmare. We’ll focus on how teams are introducing guardrails that protect source code, credentials, and infrastructure while still letting developers move fast. No policy decks. No buzzwords. Just real examples of how AI agents are being used safely inside modern dev environments. **You’ll walk away with:** * \- A clear understanding of what AI governance actually means for developers\, not just security teams * \- Insight into why AI agents need different permissions than humans and where most teams get this wrong * \- Practical examples of how guardrails can speed teams up instead of slowing them down * \- A simple mental model you can apply whether you’re experimenting with AI locally or rolling it out across a team **Who this is for:** \- Beginner → intermediate software developers \- Platform engineers and DevOps folks supporting dev teams \- Anyone using \(or wanting to use\) AI tools beyond simple autocomplete **Agenda:** \* 6:00pm\~6:30pm: Checkin, Food and Networking \* 6:30pm\~6:45pm: Welcome/community update \* 6:45pm\~8:30pm: Tech talks and Q&A \* 8:30pm\~9:30pm: Open discussion & Mixer **Tech Talk: AI Governance for Developers** **Speaker:** Eric Paulsen, Field CTO, Coder **Abstract:** In this session, we will deep dive into AI governance for developers. We will explores the often-unseen risks developers face when using AI tools—from unintended data exposure to tool lock-in—and how teams can implement lightweight, developer-friendly governance. Learn how to build secure, standardized AI workflows that provide guardrails without slowing innovation, so you can ship with confidence. **Speakers/Topics:** Check the [event website](https://www.aicamp.ai/event/eventdetails/W2026021910) for speakers and topics. If you have a keen interest in speaking to our community, we invite you to submit topics for consideration: [Submit Topics](https://forms.gle/JkMt91CZRtoJBSFUA) **Sponsors:** We are actively seeking sponsors to support AI developers community. Whether it is by offering venue spaces, providing food, or cash sponsorship. Sponsors will not only speak at the meetups, receive prominent recognition, but also gain exposure to our extensive membership base of 20,000+ AI developers in London and 500K+ worldwide.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll 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, we’ll 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 isn’t) --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 you’re 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. **YouTube Link** TBA
