Jakarta Faces is now much faster on GlassFish
GlassFish 8.0.4 renders the tested JSF pages about three times faster than the previous version. The same benchmark shows that GlassFish now renders JSF pages as fast as WildFly, Payara, and Tomcat.

An amazing engineer can still have little impact in the wrong culture.
🔴 Power: follow authority
🟡 Rules: follow process
🟢 Generative: analyze context & trade-offs
Sometimes the bottleneck isn't engineering talent. It's the organization.

Software governance often fails in two directions:
🌪️ Wild West → autonomy without shared context
🏛️ Bureaucratic → control through prescription
🧭 Context-Driven → autonomy + guardrails + accountability
Inspired by Westrum’s culture model.
