When we help a company migrate a legacy system, we get a few weeks to understand a codebase that grew over decades. Codebase Blueprint is the tool we built for that. In this article I follow one change request through an open-source IBM i application, from the field definition to screens, programs and a hard-coded length hidden in a copybook. The post Codebase Blueprint: it all started with Legacy Codebases appeared first on Federico Tomassetti.
In the world of programming, we are asking ourselves questions about the future of the developer—or, more importantly, about whether developers have a future at all. What is going to happen to us? This makes me think of the “circle of competence” discussed in the book The Art of the Good Life. The author argues […] The post The circle of competence for developers appeared first on Strumenta.
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.

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. The post Why Gherkin Is the Right Testing Tool for RPG Migration — And It Has Nothing to Do With BDD appeared first on Strumenta.
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 Strumenta.
Software isn't being replaced by LLMs, it's being fronted by them, with the deterministic core (schemas, constraints, processes) staying as essential as ever. The post What Is Software, and Will LLMs Replace It? appeared first on Strumenta.
AI Coding Feels Like Using an Unreliable Compiler Every developer I know is asking roughly the same questions about LLMs. Yes, there are LLM-fanatics and LLM-skeptics, but most are LLM-confused: sometimes LLMs seem amazing and sometimes they seem so dumb one wonders why we are using them in the first place. So we keep asking […] The post AI Coding Feels Like Using an Unreliable Compiler appeared first on Strumenta.

Embarking on an RPG-based ERP/MRP system modernization is undeniably complex. But it’s also highly rewarding when aligned with your business’s long-term success. By addressing both the technical and strategic facets, you turn an aging system from a liability into a competitive asset. Let’s outline the 7 steps in a legacy modernization project: Step 1: Assess […] The post 7 steps in a Legacy Modernization Project appeared first on Strumenta.
Key Takeaways Legacy software is tolerated because, let’s face it, it works, and works well. But that’s no longer good enough. Nowadays, it limits an organisation’s strategic options. Legacy software can slow down, or make strategic plans more expensive or complicated than they need to be. Whilst legacy software is considered stable, the real risk […] The post 7 Reasons Why CEOs Should Modernize their Software appeared first on Strumenta.
