It’s striking how many organisations still struggle to identify quality problems as early as possible. I always find it fascinating what these older books can still teach us. It’s a reminder that while technology evolves, the fundamentals of good software engineering remain timeless. Perhaps the real challenge isn’t learning new tools, but remembering the lessons we’ve already been taught. (2/2)

A while back, I was fortunate enough to find a second-hand copy of *Object-Oriented Software Engineering: A Use Case Driven Approach* which was almost as good as new. First published in 1992, the knowledge it contains remains remarkably relevant today. For example, I came across this paragraph:

End-to-end is further than you think πŸ˜„

Not sure how it is in your country but when our politicians scream about food security they neglect the fact that about 75% of Belgium's agricultural area is used to grow animal feed. And here's the shocker: 75% of the meat produced in Belgium is exported.

Breaking: New study using observational constraints projects that the Atlantic Ocean circulation #AMOC will weaken ~50% by 2100, even for medium emissions and without Greenland melting. Seriously bad news.

Critical Atlantic current significantly more likely to collapse than thought

Scientists say finding is β€˜very concerning’ as collapse would be catastrophic for Europe, Africa and the Americas

Any government that isn't right now accelerating plans to transition to 100% clean, renewable energy is either:

a. Incompetent
b. In the pockets of people who'd rather they didn't
c. a & b

"The best engineering is always borne of constraints, and the constraint of our time places limits on the cognitive load of the system that we’re willing to accept. This is what drives us to make the system simpler, despite its essential complexity."
