• 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]

• Event Store at DDDEU 2023 - Event Store is excited to be joining this year's Event Sourcing Live, DDD Foundations, and DDDEU as a Platinum sponsor, taking place from 7th - 9th June. [Event Store blog]
• Dependency Composition - Developers commonly ask "what framework should we use for dependency injection". Daniel Somerfield explains why this is the wrong question, instead we should focus how to have clearly separated modules with a simple composition mechanism between them. He illustrates how he approaches this in TypeScript, with a minimalist "function-first" approach, on a simple example application separating application logic from persistence. [Martin Fowler]
• Event Store x DDDEU meet-up - Event Store is returning to DDDEU as a Platinum sponsor. So we thought it would be great for us all to get together before the main event. If you're a DDDEU attendee, join us at the Event Store x DDDEU Meet-Up on Wednesday 7th June at 7.15 pm. Your first drink will be on us. [Event Store blog]

• Anti-patterns in event modelling - I'll just add one more field - Programming origins are in mathematics. Scientists like John Von Neumann and Alan Turing built the foundations for today’s computers. That… [Event-Driven by Oskar Dudycz]
• EventSourcing Testing Patterns - Below are the common patterns I use when writing tests for an EventSourced application. I’m documenting them here because I mention them regularly and I needed a place to point people to. I believe I talk about them in some of my Temporal Modelling talks. Surely these patterns deserve more explanation. [Mathias Verraes]

• From Music to Languages and Models (DevJourney Podcast) - On the DevJourney podcast, Tim Bourguignon asked me to talk about my career. Abstract Mathias placed the start of his journey with both hands on a TRS-80 computer and no other games to play than a compiler and the BASIC language. But fast forward a few years, we spoke about his music studies, his work creating music for ads and movies, and how programming came back as a hobby, which finally took precedence. We then jumped with both feet into languages and modeling. We spent the rest of the interview talking about interactions and how models serve us programmers and help our domains innovate. There’s a transcript at the DevJourney site. [Mathias Verraes]
• Emacs xref stopped working on Macs with dumb-jump - Recently I found that xref in Emacs had stopped working for me on my mac laptop. Today I finally tried to figure out what went wrong. xref is just a front-end, all the work is done by backends. It took a while for me to realize (ie remember) that I was using the excellent dumb-jump package as the backend. dumb-jump uses a range of fast search commands (such as ag and ripgrep) to detect references without using the awkward tags tables that Emacs used to rely on. The command flow between xref and dumb-jump is difficult to follow, but looking at the dumb-jump customization page alerted me to dumb-jump having a debug option. [Martin Fowler]

• Building a scalable and reliable event-driven architecture with EventStoreDB and Kafka - EventStoreDB and Kafka are two popular technologies that can be used together to build a highly scalable and reliable event-driven architecture. Let’s go into more detail about what these technologies are and how exactly they complement each other. [Event Store blog]
