# Beginners Hands-On Workshop: Breaking Down OpenClaw: From Minimal Installation Mode to Full-Featured Installation Mode w/ Your Own Custom Skills & More... **Registration to this event is only valid through the Luma platform:** [https://luma.com/it7a6h53?utm_source=meetup-dot-com](https://luma.com/it7a6h53?utm_source=meetup-dot-com) Hello code campers! Since **OpenClaw**, both as a project and as a tech movement, is growing, and since there is so much happening in this space, we've decided to dedicate the next **FreeCodeCamp \| AI** almost entirely to **OpenClaw,** especially following the success of the previous event. This is quite relevant since AI is moving soooo fast nowadays, making everyone scratch their heads confused while making some feel overwhelmed or have a small sensation of AI news fatigue. We will try to break down what this whole project is all about and whether or not all the hyperbolic statements about what this system can do are true. The aim for this workshop is to go through the setup process (it will hopefully take less time compared to last time because the maintainers of this project are constantly improving things), focusing on how to install the agent not only locally (virtualised, of course) but also in the cloud. We will probably look at AWS and GCP with the caveat: if you have your own server, which we encourage you to look into, the same will apply. This will be our **6th** event in our series of **local-first, open-source** AI events; therefore, we will try to focus on building a setup that doesn't depend on Big Tech but on smaller open-source tech instead. People who already have OpenClaw installed will be guided to customise it to use local LLMs or at least privacy-first cloud-based AI systems (that is because an individual's private ideas and personal project are their personal moat). At the end, we will be looking at what **SKILLS** are in the context of agents, how to build them, and if we have time, we will look at use cases for OpenClaw or, alternatively, look at emerging open-source AI agent toolkits like Pi. This workshop is open to all levels, from beginners to experts. Bring your laptop (make sure it's fully charged as local LLMs tend to be power-hungry), and don't forget to bring your coding gear (hoodie). This workshop will be accompanied by a guest speaker (full details TBA). *** ## Prerequisite First and foremost**, VERY IMPORTANT**, a VM (Virtual Machine) system like Docker/UTM for MacOs or WSL for Windows. Lastly, a local install of Ollama / LMStudio (but if you don't have any of that, don't worry, come a bit early and we will help set you up). If you want to take a quick look at the slides from the previous events fell free to do so: [https://andysign.github.io/ai-london-01/](https://andysign.github.io/ai-london-01/) (Ollama); [https://andysign.github.io/ai-london-02/](https://andysign.github.io/ai-london-02/) (LangFlow, not really related but still) [https://andysign.github.io/ai-london-03/](https://andysign.github.io/ai-london-03/) (private RAG w/ Anything LLM) [https://andysign.github.io/ai-london-04/](https://andysign.github.io/ai-london-04/) (AI-native browsers) [https://andysign.github.io/ai-london-05/](https://andysign.github.io/ai-london-02/https://github.com/andysign/ai-london-05) (OpenClaw basics) *** ## Agenda for the evening (Subject to change) **18:00 - 18:30 Arrival and networking** Mingle with fellow developers over refreshments. **18:30 - 18:45 Introductions (What is Local-First?)** Intro and a bit of audience engagement **18:45 - 19:40 Workshop** ​Hands-on technical workshop (if you are non-technical it's OK, tag along). **19:45 - 20:15 Guest Speaker (TBA)** **20:15 - 21:00 Networking** **21:00 - Closing remarks and follow-up** **END:** Carry on the fun at a nearby pub which is right @ the corner. *** ## Event Venue We'd like to extend a heartfelt thank you to **Encode Club**.

Please register here: https://hazelcast.com/resources/resilient-java-in-production-meetup/ ### Modern Java systems don’t fail all at once. They fail under load, during warmup, and sometimes days after a “successful” zero-downtime deployment. Join us for an evening focused on real-world resilience in production Java systems, from JVM performance stability to the hidden risks of mixed-version state during rolling upgrades. Come for the talks, stay for the conversations. Food, drinks, swag, and a LEGO® raffle included. ### **Special Guest: Simon Ritter** Java Champion and Deputy CTO at Azul, Simon Ritter shares how to make JVM performance more resilient by reducing latency risk from GC, warmup, and JIT behaviour without changing application code. ### **Hazelcast Session** Zero-downtime rolling upgrades in distributed Java systems are hard when multiple versions of the same service and data model must run concurrently and share state. Using Hazelcast and Hazelcast Compact Serialization, we’ll show practical Java examples and tests that demonstrate how mixed versions behave and how to make those upgrades resilient in real systems. ### **What’s in Store?** * Two technical talks on resilience in production Java systems * Food & drinks included * Swag + LEGO® raffle * Networking with the local Java community Please register here: https://hazelcast.com/resources/resilient-java-in-production-meetup/

**About the London Software Guild** ​The London Software Guild gathers developers, architects, and teams across London who care deeply about the craft of building great software. No fluff, no vendor pitches — just people who take the work seriously, sharing what they've learned the hard way. *** ## ​**Tonight's Speakers** ## ​**🎤 Kieran — Founding Engineer, Demand-Genius** ​Kieran is a founding engineer at Demand-Genius, working to close the gap between how humans and machines perceive your brand versus reality. Background in electrical & electronic engineering, previously working on real-time payments systems, high-scale distributed dynamic rules engines, and reverse proxies. Third Start-Up/Scale-Up (because I'm dumb and have never learnt my lesson). ​ **Talk: The Statistical (Un)Certainty That Our AI Co-Founder Ruins Everything** ​We have handed the most powerful text prediction machines ever built the keys to our codebases. They write code that is statistically likely to be correct. But "statistically likely" and "correct" are not the same thing. As we move toward autonomous multi-agent systems writing production code at machine speed, that gap becomes the central engineering problem of our time. ​Code is not text. It is a formal, deterministic, mathematical structure that happens to be serialised as text. Every tool in the agentic coding stack — retrieval, editing, version control, coordination — treats it as text. ​This talk argues that the answer isn't better frontier models. It's better systems around models. Specifically, the engineering disciplines we've used for a century to control uncertain systems — feedback loops, formal verification, dependency analysis, and control theory — are the missing layer between "AI can write code" and "AI can write code you can trust." *** ## ​**🎤 Andy Roberts — Senior Engineering Leader** ​Andy Roberts is a senior engineering leader with 25+ years of experience — the kind where you've actually written the code, run the teams, and been in the room when things went wrong at scale. Previously Head of EMEA Enterprise Solutions at Apollo GraphQL, where he helped companies like [Booking.com](https://booking.com/), PayPal, and The New York Times stop arguing about their APIs. Before that, Head of API Engineering at RS Components, wrangling 11 teams. Has strong opinions about federated architecture and isn't afraid to use them. ​ **Talk: Built for Browsers, Billed by Tokens** *Your microservices solved for latency. AI agents are solving for context. Nobody told your APIs.* ​Every era of software development has been defined by a constraint that reshaped architecture. In the database era we optimised for round trips. In the web era we obsessed over latency. Mobile forced us to think about bandwidth and battery. Each shift required new instincts, new patterns, new defaults. We're in the middle of another one. ​The AI era introduces a new constraint: context. Language models have finite working memory, and every API response your services return goes into it. The kitchen-sink response payloads that work fine for browsers are quietly making your AI agents more expensive and less capable — and the cost is almost entirely invisible in your existing dashboards. ​This talk maps the constraint transition from latency to context, shows what it means for the microservice APIs you have today, and offers five concrete things you can do about it without touching a line of existing backend code.

**The theme for this our next meeting is:** Welcome to our friendly and supportive Community. Where do we meet and really connect with other gay men in London? We Do in Covent Garden! # **Theme of the month:** Personal Growth & Empowerment Developing assertiveness and boundary-setting skills. Practicing vulnerability and authentic expression. Exploring creativity, play, and joy as healing. Gratitude, strengths, and future goals. **Our discussion themes would always be advertised in advance.** We are not only changing our name, we will also from now on advertise the topic we’ll be discussing before each meeting, so that you know exactly what to expect before signing up for each particular meeting. Please see the list on our MeetUp profile for potential universal themes relevant to gay/bisexual men, to be covered in our sessions. Ideas are always welcome! *We offer workshops unlike other gay/bisexual men's therapeautic discussion groups.* **A Speaker** We will at times provide a Speaker for our meetings kickstarting interesting and stimulating discussions. The Speaker can be an expert in their field such as for example an author, a therapist or a philosopher but we are welcoming any of our members to be a Speaker or a demonstrator of exercises such as massage, pilates or yoga. Or perhaps you would want to talk about your profession, if you feel it has relevance to our group. You would just have to contact Dan first for a discussion and planning. **Frequency of meetings / fee** In 2026 we’ll only have one meeting per month in person at the City Lit College in Covent Garden and one meeting online. If there is a demand for more in person meetings we’ll consider having more. We are happy to confirm that our entry prices won’t be raised and that in person meetings remain at £10. Online meetings will be FREE in January and February after which it will be £5 to attend. **Walks / museum visits** We will continue offering our occasional walking trips and also now include gay/bisexual themed history walks and visits to Museums. WHAT WE ARE: We are a group of supportive and insightful great men and we are looking forward to including you - this is what we do: CONNECTING - It is a place where you will be able to connect with other gay and bi-sexual men and where you can exchange your life experiences with them and your everyday feelings, no matter what those feelings may be - and also a place where you will be able to just be with others who live similar lives to you. EXPLORING SAFELY WITH SUPPORT - It is a place where you will experience support and growth and where you can feel safe enough to explore and reflect your feelings and life stories. Sharing is at the heart of the group but you share however much you are comfortable with - you're in charge. CREATIVE STATE REGISTERED THERAPY - It is a therapeutic discussion group which at times offers workshops and borrows elements from Creative Arts Psychotherapies. The group is based on the Creative Arts Psychotherapy/Dramatherapy and counselling work I provided ongoing for the charity Positive East in London. WHO IS IT FOR: This group is for men over 18 years old who either identifies as gay or bi-sexual or men who has sex with men - or feel emotionally connected to other men. SOCIAL OPPERTUNITY: We offer a social oppertunity in the local pub after the meetings. New members are always welcome as as well as our much appreciated familiar faces! Address: City Lit, 1-10 Keeley St, London WC2B 4BA Time: 6:30 - 8:00 PM The social part: There is certainly an opprtunity for social drinks after each meeting.

## Details Welcome to the DevSecOps London Gathering March Event on Wednesday 26 March. We bring you two amazing talks, as well as the usual conversations, pizza and beer! 📍 **Hosted at Autogen AI, Pentonville Road, London** 📅 **Wednesday, 26 March** 🕕 **6:00–8:00 PM** ## Talk 1 **Abstract:** Software supply chain attacks are no longer rare or theoretical. They are happening every day. Recent ​ incidents show how easily malicious packages can enter trusted registries and make their way into production systems before anyone notices. Today’s package managers host millions of components and support billions of downloads each week. That scale enables modern software development, but it also creates an enormous attack surface. Typosquatting, dependency confusion, malicious install scripts, and credential harvesting are no longer unusual techniques. They are now common and repeatable attack patterns. This session looks at how these attacks are playing out. Using malicious code detection data from Veracode, we walk-through real-world supply chain attack campaigns, the techniques attackers use, and the indicators that separate legitimate open-source packages from malicious ones. Attendees will see how weaponized components are identified, sometimes before they reach production and sometimes after damage has already begun. The talk also draws on industry research, including findings from the Veracode State of Software Security report, to put hard numbers behind the risk introduced by open-source dependencies and transitive trust. The session concludes with practical guidance for reducing exposure without slowing development. Topics include dependency controls, CI CD enforcement, malicious code detection, and continuous monitoring approaches that fit modern engineering workflows. ## Talk 2 **Abstract** [The National Archives](https://www.nationalarchives.gov.uk/ "https://www.nationalarchives.gov.uk/") is the official archive and publisher for the UK Government. Our records include physical records such as the Domesday Book and Magna Carta, along with digital records from UK Government departments, Enquiries, and other public bodies, held both on premise and in public cloud. It's vitally important to protect our digital records from accidental deletion and the increasing threat of ransomware. We therefore initiated a programme to implement immutable cloud backups using the AWS Backup service within a central, segregated AWS account. In this talk, we'll share our learnings from this programme of work, including: * why AWS Backup compliance mode vault locks are not always truly immutable * which KMS key types should be selected to support backup and restore to a central vault * the importance of Logically Air Gapped (LAG) vaults * how each AWS service has implemented backups differently * which widely used AWS database option doesn't support centralised backup * cost considerations for setting up backup plans We soon learnt that it's not just a case of "Turn on AWS Backup". To deploy a centralised solution, we needed to: * configure centralised AWS Backup vaults and vault policies * deploy components to workload accounts, including Backup vaults, EventBridge, IAM roles * select the appropriate vault type depending on AWS resource type We decided to implement our solution as an open-source, public Terraform Module which deploys immutable AWS Backups across an AWS Organization, to handle this complexity, and simplify onboarding new accounts and resources to be backed up. You'll come away with an increased understanding of AWS Backup, an appreciation of its complexity and limitations, and the opportunity to greatly simplify deployment of truly immutable backups across your AWS accounts, using our public Terraform module.

Hi Architects, Welcome to our the second AWS London Well-Architected User Group Meetup!!! 🥳🥳🥳 Due to the huge demand we saw for our inaugural meetup we have gone bigger with a new venue. Dragon Hall Trust, 17 Stukeley Street, London WC2B 5LT The AWS London Well-Architected Meetup is the latest chapter in the most popular AWS Meetup group globally. At each meetup we cover off various pillars of AWS best-practice in detail including insights from industry leaders that specialise in the Well-Architected Framework. We'll be announcing more speakers and topics over the coming weeks. **Speakers** * **The Philosophy Behind Well-Architected** **Philip Fitzsimons (Fitz)** \- Ex\-AWS \- Co\-authored the AWS Well\-Architected Framework\. The Well-Architected Framework started at AWS but has since been adopted by every major cloud vendor and beyond. Why did it resonate so widely? In this session, Fitz, who led the Well-Architected initiative at AWS from the beginning, explores the philosophy behind the framework, how it was intended to shape architectural thinking, and the mistakes teams commonly make when applying it. Drawing on lessons from seeing thousands of real architectures, he will explain how to approach Well-Architected reviews in a way that actually improves systems rather than just generating checklists. * **Running your first Well-Architected Review: A Live Walkthrough** **James Harding** \- Technical CSM \- Green Custard Curious about how a Well-Architected Review works in practice? In this session we'll run a live walkthrough using the AWS Well-Architected Tool, showing how to define a workload, answer the review questions, identify High Risk Issues and move on to an actionable improvement plan. * **Building Your Infrastructure: "Self-Hosted vs. Managed"** **Mykola Boiko -** Backend Developer - Ultralytics What does it really cost to build and operate your own infrastructure? Mykola Boiko shares real-world lessons from scaling a globally distributed AI platform using self-hosted infrastructure before gradually migrating services to AWS. Through stories of building replication, caching, observability, and multi-region reliability from scratch, the session reveals the hidden operational complexity and costs behind running everything yourself. The journey highlights key principles of the AWS Well-Architected Framework including Reliability, Performance Efficiency, Operational Excellence, and Cost Optimisation and shows why managed cloud services can dramatically reduce operational burden while improving scalability and resilience. More speakers to be announced soon. So come join us at 7pm for a 7.30pm start, including drinks, snacks and friendly networking after our talks :-) \*\*\*NB: No entry to the building after 7.30pm.\*\*\*

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Builders, creators, architects, admins, consultants - come one, come all. This one's for you. We're bringing a little friendly competition to the Columbus ServiceNow community while highlighting the cool things people have built on the platform. Five presenters will take the stage to showcase something they've built, solved, designed, or imagined on the ServiceNow platform - and a panel of judges (plus YOU, our amazing audience) will score them live. So basically, America's Got Talent but make it ServiceNow's Got Talent. Bring a notepad if you'd like 'cause you'll definitely be learning something new. Each presenter gets 10 minutes max to wow the crowd with: • A demo • A real-world business solution • A bold idea • A UX transformation • Or a creative use of the platform Judging Criteria: 🏆 Business Value 🚀 Innovation ✨ User Experience This event is about celebrating ideas, sharing knowledge, and showing how ServiceNow can drive both business impact and meaningful user value. Come learn. Come support. Come get inspired. Refreshments and bites will be provided. And maybe next time… you’ll be on stage.
