The tool measures metrics including cyclomatic complexity and maintainability, identifies problematic files and refactoring points, and is free while in beta. The article compares it with enterprise-oriented static-analysis products. ### Source excerpt KDP Software has worked the IBM midrange platform since 1985. Their new RPG Metrics tool measures cyclomatic complexity, maintainability, and RPG Free convertibility across your RPG source. It is free during beta, it took me minutes to get a number out of it, and when I had questions the founder answered them himself.

It presents behavioral equivalence and stakeholder sign-off as more important migration outcomes than test coverage alone. ### Source excerpt Everyone benchmarks RPG migration test suites on coverage. That's the wrong metric -- the real deliverable is behavioral equivalence a non-programmer will sign off on, and Gherkin is the only format the people who actually know the rules can read.

It cites the AgentModernize study, where the best reported result reached 19.4% behavioral equivalence, and describes gaps between extracting business rules and implementing them faithfully. ### Source excerpt AI-assisted RPG migration tools report high compilation success rates while silently failing on behavioral equivalence -- packed decimal truncation, activation group persistence, and cycle logic. The benchmarks show why, and what a real accuracy test looks like. The post AI RPG Migration Can Compile and Still Break Business Logic appeared first on Federico Tomassetti. ## Gamification 2.0.

It recommends choosing a dominant game genre that matches an app's core activities, aligning that genre with user psychology, and designing satisfying intrinsic interaction loops before adding points, badges, or other extrinsic rewards. ### Source excerpt Part 5 of the "Gamification Series." A framework for developers: from theory to practice Everything I've outlined so far is meaningless if you can't apply it. So let me give you a practical framework for actually implementing Gamification 2.0.

It argues that different game genres attract players through different psychological motivations, so teams should align an app with an intentional genre instead of combining random mechanics. ### Source excerpt Part 3 of the "Gamification Series." Genre matters: the missing framework Here's the most important thing most gamification designers miss: there is no single "game psychology." When a product team says, "Let's add gamification," they're making the same mistake as saying, "Let's add music," without specifying what kind of music. Jazz? Heavy metal? Classical?
