What is Groovy and why should I care?
Hello again, it's me, Adam. Earlier this year, I finished my self-published book, Learning Groovy, which is about, well, learning Groovy. It also covers the top Groovy-based tools and frameworks, Gradle, Grails, Spock, and Ratpack.
I've enjoyed using Leanpub as a place to work on my books (What's new in Java 8 and others). It is really easy and developer friendly. It uses a Dropbox folder and you can write your book in Markdown (which I did). I've enjoyed a fairly constant trickle of purchases, but I was frustrated that I never had enough time to devote to the other huge part of self-publishing: marketing. To be really successful with a book, it needs to be marketed really well. You need to put in a lot of time and money. So, when it came to publishing "Learning Groovy," I approached several publishers to do the marketing for me.
Luckily, one of them accepted, and I'm currently in the process of final edits (publisher shall remain anonymous for now).
This means that you can only get the self-published version of "Learning Groovy" for a limited time. Once it goes to the publisher, I have to take down all my versions per the contract.
"What is Groovy and why should I care?" you ask? First of all, what rock have you been living under? Secondly, Groovy is a mature and flexible open-source language that runs on the JVM. Want to learn more about functional programming, want optional dynamic typing, easy restful services, easy reactive web applications (Ratpack)? Maybe you to learn about the most popular build framework and testing frameworks for Java (Gradle and Spock)? Groovy is where it's at.

Despite widespread industry recommendations, a new ETH Zurich paper concludes that AGENTS.md files may often hinder AI coding agents. The researchers recommend omitting LLM-generated context files entirely and limiting human-written instructions to non-inferable details, such as highly specific tooling or custom build commands.

DoorDash has rebuilt its Dasher onboarding into a unified, modular platform to support global expansion. The new architecture uses reusable step modules, a centralized status map, and workflow orchestration to ensure consistent, localized onboarding experiences. This design reduces complexity, supports market-specific variations, and enables faster rollout to new countries.

OpenAI's $110B funding includes AWS as the exclusive third-party distributor for the Frontier agent platform, introducing an architectural split: Azure retains stateless API exclusivity; AWS gains stateful runtime environments via Bedrock. Deal expands the existing $38B AWS agreement by $100B and commits 2GW of Trainium capacity.

Sophie Koonin discusses the realities of large-scale technical migrations, using Monzo’s shift to TypeScript as a roadmap. She explains how to handle "bends in the road," from documentation and tooling to setting measurable milestones. Sophie shares vital lessons on balancing technical debt with feature work and provides a framework for deciding if a migration is truly worth the effort.
