Back in the late nineties I was working for a small ISV and was a dev lead on a project to develop a C++-based visual programming environment and runtime for monitoring SCADAs and PLCs. It got used by a few customers, but ultimately wasn't successful and was discontinued when the company did what we'd now call a pivot. I moved on to a company in the financial sector and my employer acquired the rights to use this software (a decision I had nothing to do with). We ended-up using it as a way to embed customer-specific customisation scripts into a cloud-based product - something that it had never been designed to do, but which ultimately worked quite well. A couple of weeks ago I finally replaced it with a much smaller and more focussed body of C# code, 16+ years after it was initially developed.
