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. balusc.omnifaces.org/2026/07…

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. #SoftwareEngineering #Leadership

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.

You don’t need to become a manager to become a leader. 👨‍💻 The more senior you become as a Software Engineer, the more your impact depends on: 🤝 trust 💡 influence 🗣️ communication 🧭 technical direction You can stay an IC. But you can’t ignore leadership forever.

I chose Software Engineering partly because I thought: 💻 “I won't have to deal with people.” Huge mistake. 😅 Software is built: 🤝 with people 👥 for people 🚀 through people The further you grow, the more communication matters. #SoftwareEngineering #Leadership
