We are back again with another chapter of the London MongoDB meetup for november. We will be having a good time at the London MongoDB office at Blackfriars.

Talk Details First Speaker: Sani Yusuf Title: The Realm of Migration - In 2014\, MongoDB announced a major deprecation of the client-side SDK for using the Realm SDKs with Atlas. This caused significant disruption\, as applications built with this popular setup faced extinction. In this talk\, Sani Yusuf will demonstrate how Claude Code\, an AI tool\, was utilised to create a migration pathway using the NestJS API and Auth0 to transfer sensitive healthcare data with minimal downtime.

Second Speaker: Abishek Bagga Title: Schema Design Skill track - Abishek will lead the Schema design skill track by MongoDB\, and participants will be able to receive this Skill Badge and showcase it as an earned feat. The Schema Design Skill track will teach attendees the ins and outs of MongoDB schema design.

BlaBlaCar a économisé plus d'1 million d'euros par an en arrêtant l'externalisation de la modération de contenu textuel et en développant « Sphinx », un outil interne conçu sur Vertex AI. Raphaël Berly, chapter lead data science, nous présentera le pourquoi et le comment des embeddings utilisés pour représenter le texte, la mesure de la qualité avec les modèles d'IA générative, ainsi que les principaux enseignements qui ont permis à ce projet de passer de l'idée au déploiement sur les interfaces de millions d'utilisateurs en moins d'un an.

As AI agents increasingly operate autonomously across networks, establishing robust identity and precise access controls is critical to fostering trust and responsible interaction.

This LFDT Belgium Meetup will explore the foundational challenges of recognizing and delegating AI agents securely, as well as enabling fine-grained data access and persistent agent memory through innovative wallet solutions.

Key questions include:

• How can agents be reliably identified and trusted across diverse environments?
• What delegation models ensure agents act appropriately on behalf of users?
• How can granular permissions enforce least-privilege data access?
• Where should agent-generated data be securely stored for interoperability and persistence?

19:00 - 19:10 Welcome & introduction by Howest Cyber3Lab

19:10 - 19:40 Agentic Wallets™: Enabling Fine-Grained and Persistent AI Data Access with Solid and MCP Geoff Pirie - Director of Product\, Inrupt Geoff is the Director of Product at Inrupt - the company co-founded by Sir Tim Berners Lee who invented the Worldwide Web. Geoff has a long history of enterprise software development and product management, having worked with IBM for 23 years prior to joining Inrupt.

19:40 - 20:20 Scaling the Agentic Web: New Challenges and Areas of Innovation Andor Kesselman - Founder\, DIF Labs As multi-agent systems move from theory into deployment, one of the most urgent challenges is establishing agentic identity - how agents are recognized\, authenticated\, and trusted across diverse networks. This session will examine the complexities of delegation (how agents act on behalf of humans or other agents)\, the role of hardware attestations in anchoring trust\, and emerging patterns of human–agent interaction. We will also discuss how agents differ fundamentally from broader AI systems and frameworks to think about them. Drawing on evolving work at the Decentralized Identity Foundation (DIF) and MIT’s Project NANDA, we will highlight emerging frameworks designed to scale the agentic web responsibly.

Andor Kesselman is a seasoned CTO and recognized leader in Decentralized Identity, with a deep focus on multi-agent systems and governance. He has been researching agent architectures since 2018, including early work in DecPOMDP that anticipated today’s advances. His startup, AgentOverlay, focuses on bridging multi-agent theory with years of work in decentralized identity. He helps lead the Bay Area chapter of Project NANDA and chairs the Technical Steering Committee at the Decentralized Identity Foundation (DIF), where he is also launching the Trusted AI Agents Working Group. His work centers on the emerging challenges of multi-agent governance-from identity and trust to policy enforcement-critical issues that must be solved to responsibly scale the agentic web.

Knowledge Graphs – A crash course

In Gartner’s 2024 Artificial Intelligence Hype Cycle, there are two big movers. The most mature of the two is the topic of this session: "Knowledge Graphs" which, according to Gartner, just reached the "Slope of Enlightenment" ("AI Engineering" - now reaching the "Peak of Inflated Expectations" - is the second). But there is more to "Knowledge Graphs" than their relevance to the current hype darling, “AI.” Using W3C standards, Knowledge Graphs model all kinds of complex sets of entities and their relationships in an intuitive way. Compared to “plain" graphs, they offer flexible schema languages, machine-readable semantics and the direct use of existing open schemas and ontologies. In this session, you will first get a (short) refresher on graphs and then learn about: - The difference between property graphs and knowledge graphs. - RDF: The base of the W3C Knowledge Graph standard. - SPARQL.: The knowledge graph "SQL". - OWL: The open world assumption and graph-based reasoning. - SHACL: The closed world assumption and constraining. - Some of the key players implementing Knowledge Graph databases. - How to start by yourself.

Christoph Seck

Christoph is a Global Data Architect at Kühne + Nagel. Previously, he worked as a BI and data architect for various system integrators, implementing data platform projects mostly within the Microsoft ecosystem, was a long time Microsoft P-TSP and Visiting Lecturer at the University of Hildesheim. He is co-founder and chapter lead of the PASS Group Hannover/Göttingen and a regular speaker at PASS groups and conferences, covering topics such as data strategy, databases, agile methodologies, and blockchain.

In this workshop you'll learn how to:

Use Streamlit to build a conversational analytics application using Cortex Analyst How to improve your application's accuracy by providing context using Cortex Search and Semantic Models How to call Cortex Analyst using Streamlit and REST APIs

Who Should Attend?

The workshop is open to anyone with a technical background, whether you’re a data analyst, engineer, or simply a tech enthusiast curious about the latest data trends. It's especially beneficial for those aiming to enhance their professional skill set by learning about Snowflake.

Why Attend?

Upskill: In an era where data is becoming increasingly valuable, knowing how to leverage powerful technologies like Snowflake is crucial. This workshop could be a stepping stone to help propel your career forward. Networking Opportunities: Connect with like-minded professionals and industry experts. Exchange ideas, share experiences, and build relationships that could lead to future collaborations or career opportunities. Hands-On Experience: It's one thing to read about technology, but it's another to use it. The hands-on lab ensures you don't just learn; you apply, making the knowledge stick.

Logistics

This will be a hands on session so feel free to bring your laptops so you can have a go at building something yourselves. Make sure you have a full charge on your laptops and have your personal hotspots ready as a backup!

Spaces will be limited to 60 people, and we will rely on registrations on the Snowflake Community page to gauge numbers. Please only register if you know you will be able to attend, it will help us to order the correct amount of food/drink.

First come, first served on the day, we will try our best of course but if you arrive late we may not be able to fit you in.

Karlsruher Data Community Treffen November 24

Im November steht das nächste Treffen der Datamonsters Karlsruhe an! Die geplanten Termine und Themen gibts auf der DataMonster Site.

Auch dieses Mal haben wir wieder 2 spannende Monster Sessions: Christoph Seck stellt uns Knowledge Graphen vor und Jerome Klein gibt uns eine Einführung zum Thema Power BI. Dazwischen gibt es wie immer die Gelegenheit sich mit anderen Data Monstern bei Pizza & Bier auszutauschen. Wir treffen uns wie gehabt im Karlsruher Büro des Raumsponsors scieneers.

Session 1: Knowledge Graphs – A crash course

In Gartner’s 2024 Artificial Intelligence Hype Cycle, there are two big movers. The most mature of the two is the topic of this session: "Knowledge Graphs" which, according to Gartner, just reached the "Slope of Enlightenment" ("AI Engineering" - now reaching the "Peak of Inflated Expectations" - is the second). But there is more to "Knowledge Graphs" than their relevance to the current hype darling, “AI.” Using W3C standards, Knowledge Graphs model all kinds of complex sets of entities and their relationships in an intuitive way. Compared to “plain" graphs, they offer flexible schema languages, machine-readable semantics and the direct use of existing open schemas and ontologies. In this session, you will first get a (short) refresher on graphs and then learn about: - The difference between property graphs and knowledge graphs. - RDF: The base of the W3C Knowledge Graph standard. - SPARQL.: The knowledge graph "SQL". - OWL: The open world assumption and graph-based reasoning. - SHACL: The closed world assumption and constraining. - Some of the key players implementing Knowledge Graph databases. - How to start by yourself.

Vortrag wird Christoph auf deutsch halten.

Speaker: Christoph is a Global Data Architect at Kühne + Nagel. Previously, he worked as a BI and data architect for various system integrators, implementing data platform projects mostly within the Microsoft ecosystem, was a long time Microsoft P-TSP and Visiting Lecturer at the University of Hildesheim. He is co-founder and chapter lead of the Datamonster Hannover/Göttingen and a regular speaker at Datamonster groups and conferences, covering topics such as data strategy, databases, agile methodologies, and blockchain.

Pause mit Pizza & Getränken

An dem Abend ist wie gewohnt auch für das leibliche Wohl gesorgt, nerd typisch gibt es vom Raumsponsor Pizza and Bier (& andere kalte Getränke).

Session 2: Einstieg in Power BI

Diese Einsteiger-Session bietet eine umfassende Einführung in den Datenimport sowie die Visualisierung in Power BI. Die Session richtet sich an alle Anfänger, die keine oder nur geringe Vorkenntnisse in Power BI haben. In der Session werdet ihr durch praxisnahe Beispiele und Schritt-für-Schritt-Anleitungen geführt, um das grundlegende Verständnis für den Import von Daten und die Erstellung beeindruckender Visualisierungen zu erlangen. Folgende Punkte werden in der Session ausführlicher behandelt:

- Grundlagen von Power BI - Datenimport - Datenmodellierung - Visualisierung - Dashboard-Erstellung

Ich freue mich, mit euch gemeinsam die Möglichkeiten von Power BI zu entschlüsseln!

Speaker: Jerome Klein ist ein Nachwuchstalent und hatte seinen ersten Talk beim Data Grillen 2024. Derzeit sammelt er Erfahrung beim Sprechen auf deutschsprachigen Veranstaltungen. Mit dem Thema Daten beschäftigt er sich derzeit noch als Hobby, aber das präsentieren macht ihm großen Spaß!

Organisatorisches Bitte meldet euch vorab über Meetup an, da die Teilnehmerzahl begrenzt ist.

Wir starten um 18 Uhr mit dem Event, die Vorträge dauern beide ungefähr eine Stunde +/-.

Wir freuen uns auf einen interessanten Abend und natürlich darauf, viele von euch wiederzusehen!

11:40 AM: 🎤 Marcin Chudy - Demystifying App Architecture: The LeanCode Guide

At LeanCode we developed over 40 Flutter apps, spanning from huge enterprise apps to nimble startup ventures. Some were developed by a single Flutter dev, some came into light through collaborative efforts across multiple teams. Each of them was different. Each of them presented unique challenges and taught us invaluable lessons.

In this talk, we invite you to explore different approaches to architecting Flutter apps. Central to our narrative will be the concept of architectural drivers - key factors or priorities that steer our decisions about how the app is structured and designed. We'll show how we leverage our experience when approaching new projects. Drawing from our successes and failures, we'll present our current Flutter stack which enables us to craft robust, scalable, and maintainable applications. While there is no silver bullet for Flutter architecture, we can still have some sensible defaults.

Why do we use BLoC for state management? Why not Riverpod? Why do we love hook

12:30 PM: 🎤 Danny Preussler - Ten things you heard about testing that might be wrong

Testing became an essential part of Android development. Many conference talks have been given and even more best practices have been written.

But what if, as time evolved, some of the things we thought were true, changed?

Let’s start questioning some of these in this talk: Are flaky tests fixable? Are mocks even harmful? Is DI about testing? Did we understand testing in isolation properly? Is the test pyramid still valid? And in times of AI, should we generate tests?

Come and join my session to learn more!

While often overlooked, LCP reveals when a page’s core content is truly ready, affecting how users perceive load time and usability. This talk uncovers LCP’s role, why it matters more than we think, and simple strategies to boost LCP for better engagement and rankings. Discover the hidden story behind one of web performance’s most crucial, yet understated metrics.

Did you know the speed of a single webpage element could decide if users stay or leave? Largest Contentful Paint (LCP) is that hidden hero, quietly working to load the most important content quickly. This talk unveils LCP’s role in creating faster, more engaging web experiences and why it’s key to winning user loyalty. Dive into the “unheard story” of LCP and discover practical tips to make your site not only faster but unforgettable.

4:20 PM: 🎤 Ash Davies - Navigation in a Multiplatform World: Choosing the Right Framework for your App

Navigation in mobile, desktop, and web applications is such a fundamental part of how we structure our architecture. In order to both obtain functional clarity, and abstraction from platform level implementation.

For a long time, there have been options available specific to each platform, and even options part of the platform framework itself. Though it can be difficult to find the right option for platform-agnostic code, ensuring consistency. Some go one step further, providing an opinionated guide on how to architecture your application.

In this talk, I'll evaluate the options available, how they differ, and to what type of applications they are best suited. Including how to get started with them, and the best practice guidelines on how to get the most out of them, for your application.

5:10 PM: 🎤 Vadim Makeev - You don’t know MathML. Almost nobody does

Do you speak math? Me neither. Still, math formulas have always been around: from Wikipedia articles to JavaScript APIs and even CSS docs. It looks so alien that I never had a clue how to express it on the web. Apparently, there’s a markup language for that. HTML for content, SVG for vector graphics, and MathML for math! And it’s pretty cross-browser, too. Let’s dive into the basics and quirks of the language of the universe. Even if math is not your love language, you might learn something interesting about the web platform.

Day 2

9:00 AM: Registration & Coffee 🥐 ☕️

We ship releases faster and with more confidence using ARM!

11:40 AM: 🎤 Aleksandr Gorbunov - Flutter for frontenders or There and Back Again

Every developer, regardless of specialization, may encounter the need to create a UI for a client application. The choice of technology may depend on the developer, or it may be pre-determined by the client, as happened in my case.

The peculiarity is that, coming from frontend development in JavaScript, I started building user interfaces in Flutter.

Today, there is a vast number of technologies that enable the development of cross-platform applications. These technologies are evolving rapidly, attracting large communities, and more frequently, companies are adopting them. For example, Flutter is a powerful framework that allows developers to create cross-platform applications.

With a high probability, every developer may encounter the need to use such development tools, and it’s great that frameworks like Flutter come with detailed documentation and extensive community support, making it relatively easy to start developing with them. Although, at first glance, everything might not seem smooth, and the desire to revert to familiar methods may arise.

THE TALKS

Unlocking climate data for SME carbon accounting - Joss Bennett **"**99% of UK businesses are SMEs, and around three-quarters are sole traders… they account for 43-53% of UK businesses’ greenhouse gas emissions in aggregate” (Source: UK Finance). Net zero presents a real challenge for SMEs in the UK, with tough an economic landscape and growing regulatory requirements which is taking the form of cascading requirements for climate disclosure originating from large multinationals down the supply-chain.

Increasing tools to automate data analysis, which overcome traditional hurdles of admin time and quality to reporting have emerged. Focusing on a spend-based assessment to identify areas for data improvement and ultimately collecting supplier-specific data will encourage action over paralysis to enable effective value-chain decarbonisation.

Joss Bennett, Sustainability, Energy and Carbon Reporting Lead for Perse.io. With 6 years of career operating across the UK sustainability landscape Joss has driven environmental campaigns with organisations such as Blake Made and Treeapp, respectively. This cumulated in a founding associates position, as the Lead Carbon Consultant, for Manchester based (UK) sustainability software start-up NetZero.co.uk.

Joss was a Senior Consultant at Green Economy, part of the social enterprise The Growth Company, implementing Greater Manchester Combined Authority’s decarbonisation targets. He has recently accepted a position at Perse.io to enable the widespread automation of utility data for systemic decarbonisation across the UK and beyond.

Small Data - Dealing with Climate uncertainty - Josh Hayes

Climate change is impacting everyone, and business activities are one of the primary sources of emissions, financial institutions need to take responsibility for their share of these emissions.

The Taskforce for Climate-related Financial Disclosures (TCFD) have set regulatory requirements for financial institutions to disclose their financed emissions. The requirements for disclosures is tricky, as lenders need to understand their customers' emissions. As many businesses do not disclose their own emissions, a range of methodologies must be used.

Josh will explore the data challenges faced by financial institutions, provide an explanation of the standard methodologies used to estimate finances emissions, and introduce the idea of data quality scores, a metric that can be used to indicate the quality of an emissions estimate in lieu of a quantified confidence interval.

Josh has a PhD in astrophysics from the University of Manchester in 2021, where he was using Bayesian modelling to explore exoplanetary atmospheres. After completing his thesis, he worked at NatWest, where he has been the technical lead behind the calculation of the bank's emissions. He is leading research streams into significant methodological improvements, whilst supporting on multiple additional climate initiatives.

LOCATION We'll be at Krakenflex, who are also kindly supplying catering. The capacity is limited to 90.

After the talks we'll all head somewhere local for some post-event socialising.
