Code that doesn't age against you
Why technical debt is usually discussed by gut feel — and which five metrics replace that feel with numbers a CFO can argue about.
Work journal · in motion
Sustainable software engineering, thought through in public.
solustainable is a personal project where we openly reason through three questions: how to keep code from aging against you, how to demonstrate NIS2 compliance without a consultancy circus, and how to modernize legacy systems without fooling yourself. We write here before we sell anything — and as long as there is no commercial offering, this site exists only to publish our own thinking.
Three topics that occupy us
What we're writing about here.
Each of these topics is an open question — not a finished answer, but material to think with.
Regulation without the ritual
What the NIS2 directive actually demands of mid-market companies, which twelve points carry the real weight, and where the cost lives.
Assessing legacy honestly
How a Delphi or VB6 migration is really costed, where AI helps in the assessment phase, and when the right answer is simply "don't migrate".
