• Exploring the main features of EventStoreDB - What exactly is EventStoreDB? What makes it different from other operational databases? [Event Store blog]
• A Service Boundary Homework Problem - I guess it was inevitable, but quite often I see homework problems on r/microservices seemingly assigned in some intro CS class. Peculiarities of that aside, they can be quite fun to work through as thought experiments. One recent one came up: Hi, I am working on a school app. [Jimmy Bogard]
• How to create a Docker image for the Marten application - Containerisation is something that pushed our industry much further. Generating immutable artefacts is a foundational aspect of the DevOps… [Event-Driven by Oskar Dudycz]

• Lessons Learned Running Presto at Meta Scale - Presto is a free, open source SQL query engine. We’ve been using it at Meta for the past ten years, and learned a lot while doing so. Running anything at scale - tools, processes, services - takes problem solving to overcome unexpected challenges. Here are four things we learned while scaling up Presto to Meta scale, and some advice if you’re interested in running your own queries at scale. Scaling Presto rapidly to meet growing demands: What challenges did we face? Deploying new Presto releases [High Scalability]

• Surfacing Worldviews in Design - Implicit worldviews underlie our design choices. Exposing them can generate better options. Design choices carry along the worldviews of the designer. This often is not apparent, especially when design ideas are for obvious technical improvements. Let’s look into a design … Continue reading → [The Responsible Designer]
• Surfacing Worldviews in Design - Design choices carry along the worldviews of the designer. This often is not apparent, especially when design ideas are for obvious technical improvements. Let’s look into a design challenge faced by a fictional Maker Lab. In this Maker Lab, people in the community can come in and make all kinds of things such as metal work, robotics, furniture, glasswork, 3D printing, laser cutting, lighting, electronics, … The Lab provides tools, machines, and inventory that makers can use in the maker space. The makers are supposed to use the hand scanners, and scan the barcodes on equipment and materials as they take them out for use. Sometimes makers may need something for a few days, so it’s normal that they don’t put everything back right away. [Mathias Verraes]

• Why I regret not embracing Axon Server sooner - I have been a Solution Architect at AxonIQ for over a year. Before that, I was a software developer, bringing an Axon Framework application into production with a regular Oracle database as an event store. Over the past year, I developed several Axon Framework applications with Axon Server, and it makes your life so much easier. It’s not just an event store but also a distributed message bus that automatically routes all your messages! Looking back on my time before AxonIQ, I wish I had made the jump sooner. [AxonIQ Blog]
• MediatR 12.1 Released - This release removes all scanning around behaviors, stream behaviors, and pre/post processors. That proved too problematic so you MUST register each of these explicitly with the appropriate registration methods inside AddMediatR. This also ensures that the order of behaviors and pre/post processors reflects the explicit order of registration. [Jimmy Bogard]

• Streaming events? You should be storing them. - It was 1494. Luca Pacioli - a Franciscan Monk, mathematician, and friend of Leonardo De Vinci - published a book he’d spent decades working on. Titled Summa de arithmetica, it would be the book that would see him gain his title: “the Father of accounting”. [Event Store blog]
• Seven steps to reach your business goals with AxonIQ - Follow these seven easy steps to achieve your business goals utilizing the AxonIQ Business Value Calculator. [AxonIQ Blog]
• Building Boba AI: Some lessons and patterns learnt in building an LLM-powered generative application - While it's fascinating to work directly with a Large Language Model, such as ChatGPT, it takes some skill and practice to learn how to prompt it effectively. My colleague Farooq Ali has been working on a co-pilot tool, Boba AI, for using an LLM to help generate ideas for product strategy. From this experience he as proposed eight patterns which he judges will be generally useful for building these kinds of AI co-pilot applications. [Martin Fowler]
• Follow the money to get a better design - I noticed that we, developers, struggle to follow the money. And that’s impacting our design in the wrong way. Of course, we’re pretty good… [Event-Driven by Oskar Dudycz]

• Linking Modular Architecture to Development Teams - Mobile applications often deliver features rapidly at first, but slow as a codebase builds up. These common software problems are exacerbated by the need to prioritize different features in different markets. Matthew Foster describes an example of this from his work with clients, and how using Domain-Driven Design and Team Topologies helped create a modular architecture that substantially reduced the time needed to deliver new features. [Martin Fowler]
• Exploring the 4 Major Use Cases of EventStoreDB - EventStoreDB is a powerful operational database specifically designed for event-driven architecture. It uses a state-transition data model, storing events as a fundamental building block and overcoming the challenges of traditional intentional data loss architecture. [Event Store blog]
• Meet-up, BlimpBots and Socks : A Recap of DDDEU 2023 - Last week, the Event Store team attended DDDEU, one of the largest domain-driven design conferences. As exhibitors, we were excited to talk about all things Event Store and engage with attendees. Here's what we got up to. [Event Store blog]

• Save time scavenging with EventStoreDB v22.10 - Our Event Store community matters. So when you make suggestions about EventStoreDB, we do our very best to listen and make changes. One recent change to EventStoreDB is to scavenging, so we wanted to update you on what’s changed, and why it’s better. [Event Store blog]
• Privacy Enhancing Technologies: An Introduction for Technologists - Making data open and available to all helps us all understand our world and are thus better informed to shape the policies to run it. But such openness does come with problems - one in particular is the invasion of people's privacy. Detailed census information about household income helps debate and planning for local government, but can reveal personal information that citizens reasonably prefer to keep private. Privacy Enhancing Technologies are tools that can finesse this problem. My colleague Katharine Jarmul is a data scientist who is also an activist for personal privacy. Here she introduces three of these tools that are usable now: Differential Privacy, Distributed & Federated Analysis & Learning, and Encrypted Computation. [Martin Fowler]
