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/

## 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.

**Agentic AI from Qlik: Smarter Decisions, Delivered in Real Time** Every organisation makes hundreds of decisions each day. The problem is not a lack of data, it is the inability to access the full picture at the right time. Data sits in silos, insights arrive too late, and teams spend more time searching for answers than acting on them. At our upcoming **Qlik Meetup,** we will explore how Agentic AI from **Qlik** is transforming this reality. Built on the power of **Qlik Answers**, Qlik’s **Agentic AI** framework introduces intelligent AI agents that go beyond dashboards and static reporting. These agents understand context, connect structured and unstructured data, explain the “why” behind insights, and take meaningful action. The result is faster, more confident decision making across the organisation. Join us for an interactive session including live discussion and Q&A with members of the Qlik team, where we will demonstrate how Agentic AI: * Unifies all your data sources, enabling instant access to structured and unstructured information wherever it resides * Delivers transparent, explainable analytics with clear traceability back to source data * Automates intelligently by building dashboards, triggering workflows and completing routine tasks * Amplifies team productivity by acting as an intelligent extension of your workforce * Accelerates time to value through a plug and play architecture designed for rapid deployment and measurable ROI This session is ideal for data leaders, BI professionals and analytics teams looking to move from insight generation to intelligent execution. If you are serious about unlocking the next evolution of analytics within your organisation, this is a session not to miss.

**Let's Shoot Noir Street Photography in Soho London After Dark** This mini-workshop event focuses on shooting street photography after dark. You will learn tips for low-light shooting, handheld techniques, and how to creatively use existing city lighting. Soho after dark has a completely different energy. Neon signage, theatre lights, and passing traffic create natural contrast, cinematic tones, and deep, moody shadows. The location itself becomes part of your frame, adding atmosphere without the need for a flash. This session focuses on capturing moody, neon-lit street photography using the city’s existing lights. You’ll learn to see, interpret, and use the available light creatively. Occasionally, a model will be present as a point of focus to help you practice shooting subjects in various real-world night-light conditions. *** **What You Will Learn** * **Reading Available Light:** Observe neon signage, street lamps, traffic, and reflections and use them creatively in your shots. * **Handheld Night Shooting:** Adjust ISO, shutter speed, and aperture for sharp, well-exposed images while shooting handheld. * **Creative Use of Light on Subjects:** Learn how to make people stand out using the available neon and street lighting. * **Exposure and Mood Control:** Balance highlights, shadows, and neon to capture the “noir” atmosphere. * **Quick Observation & Reaction:** Train your eye to spot photo opportunities in challenging night conditions. * **Getting to Know Your Kit:** Understand what your camera and lenses can do in low light so you can react confidently. *** **What to Bring** * **Camera Kit:** A fast lens (prime or zoom, around 35–50mm, f/1.4–f/2.8) is highly recommended for best results at night. You may bring your best lens for practice, but you may struggle more in lower-lit situations. Message me if you want advice on gear before booking. * **Essentials:** Cleared memory card and fully charged batteries. Extra batteries recommended. * **Travel Light:** Comfortable shoes and clothing suited to the weather. *** **Event Info** * **Duration:** 2 hours * **Group Size:** Max 5 * **Meeting Location:** Soho, London *** **Bonus for Members** * **FREE DOWNLOAD – Beginner Street Photography Tip Sheets:** Master Night Street Photography For Beginners Tip Sheet covering the key topics from this event.

No matter how great your painting is there are few occasions where it is not improved by a beautiful frame. High street framers will usually glue something together for you from off the shelf mouldings, good enough perhaps, but rarely outstanding. You may have seen that successful artists like [David Sawyer](https://www.instagram.com/djsawyerrba/) often use gessoed frames, which are painted up to suit the specific image. As artists we have skills in abundance and time can be made available if we choose, so making our own frames is a no brainer. David Sawyer, along with being one of Britain’s leading landscape painters, often frames his own work. As you would expect his frames are sensitive and beautiful. He is running a framing workshop which will get you going with the basics of producing hand made picture frames. **What will you be learning?** * Typical types of mouldings, what types of wood and profiles are available * The use of slips, liners and fillets * How to decide on your moulding * Measuring the artwork * Setting up and calibration of the Morso (guillotine) * Cutting the moulding * Getting to know the types of glues available * Setting up the underpinner and joining * Clamping and reinforcing the frame We will provide one small frame to be gessoed and gilded, and each participant will also create a new frame of a bespoke size. Working with professional framing equipment, you’ll choose, measure, and cut your mouldings, then join and glue your frame to your own specifications. If you have any works on paper you’d like to frame instead, please drop us an email so we can bring the necessary equipment. Expect to pay a little more for materials, £15-£27 for an average frame. You don’t need to bring anything to this workshop other than a picture you’d like to frame and a notebook. We plan to eat together, we’ll optionally provide an indulgent but healthy lunch with vegetarian options for our usual modest charge. **Students who have been inducted, or who already know how to use the machines safely, will be able to use the equipment in the afternoon.** Please get in touch to receive a discount for purchasing a half-day pass.

**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

So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.
