While the world seeks a path to peace, Russia responds with missiles.

The overnight attack on Kyiv shows a deliberate choice to escalate and mock the peace efforts.

Russia must stop the killing and negotiate.

With vibe coding tools going mainstream, it’s entirely predictable we’ll keep seeing many of these cases.

Eventually, the “better” vibe coding apps will patch most of these (not all!). Till then we’ll see all information leaks, security issues and trivial to “hack” such sites

The URL used had the path /management/heapdump, possibly a Spring Boot app. I never imagined that my contribution github.com/spring-proje... in 2016 would result in this disaster 9 years later. In Spring Boot, you should set management.server.port and never expose management endpoints externally.

Eighty years ago, enemies laid down their arms.

Since then, we, Europeans, have built something extraordinary: a Union of peace, democracy, and solidarity. An anchor of stability.

Our Union was born as a peace project, and it remains one today.

Psychological safety is NOT about lack of disagreement.

Psychological safety REQUIRES:

* disagreement and debate
* setting standards for behavior and performance, and enforcing them
* telling people things they don't want to hear
* courage, from the bottom up
* humility, from the top down
