Notes

• Java is a passport to the world – spoke at 50 user groups in hoor of turnig 50
• Celebrated Paris JUG’s anniversary in Eifflel Tower
• Ukrainian flag slide

Agile

• good to say that, now talk about what do
• Hates word – Scrum-master – Agile Manifesto does’t say SM
• Love ceremony and rituals
• Easy to hide from what really do
• Also hates word velocity – sustainable and producing results is what matter
• TDD – ticket driven development
• Agile is really feedack driven development
• Cost of failure low if train leaves every 30 minutes vs plannig a flight

Java

• Java now evololving faster
• Java 8 was game changer because of streams
• “Java late to party but came with amazing desserts”
• Releases used to be slow because targeted features to releases. Not agile. Want to adapt plan to reality
• ”When will project loom be ready?” ”When it is ready”
• Java is not being developed on a 6 month release cycle. It is being released on a 6 month cycle
• People ask questions about feature while still remember writing it
• Can learn and adopt technologies as they come out vs all at once
• Less ceremony/redundancy

Live coding

• pattern matching with if – smart casting
• switch expression
• pattern matching with switch including conditions
• multi-line string with smart indentation (incidental whitespace
• sealed interface – use but don’t implement

My take

I don’t think I learned anything new, but Venkat is an entertaining and engaging speaker, so that’s fine! Good coverage of the new Java features in live coding
