Come along for lively, interesting conversation about a variety of topics with friendly people of all ages and backgrounds. There is a list of many interesting ideas for discussion. Everyone is encouraged to choose a question that interests them, to contribute to the conversation and to listen to one another’s answers with respect. We avoid talking about politics, religion and personal issues. There are always two hosts who make sure that everyone has a chance to speak. DON'T BE SHY - GIVE IT A TRY, EVEN IF YOUR ENGLISH ISN’T PERFECT! It is free, and there is no obligation to spend money in the café. I also promote this via other local websites, so more people turn up than it says on this site.

NOTE: the pub does not charge for our space on the understanding that we all purchase something from the bar. Please support them. I'll be there from around 7pm if anyone would like a social like a social chat before we get started. What do we mean by “consciousness” when applied to people and animals. What are the essential characteristics of “conscious” entities? Why is “consciousness” important? (As opposed to sophisticated problem-solving skills, language and other aspects of "intelligence"). How and why might consciousness have evolved? To what extent could a machine exhibit the essential elements of consciousness? If it did, would that make it conscious? Or would something always be missing – would the machine only qualify as a “simulation” of consciousness. What would be the difference? What ethical issues would arise if machines ever do achieve some level of consciousness? How would we cope with them. Would machines have rights and responsibilities? In what sense could they be held to account? and how? What motivates people to try to build conscious machines? These are deep and fascinating questions which will doubtless lead to a great discussion. Some prior reading/watching would be helpful.

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/

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.\*\*\*

## 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.

**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
