In this month’s edition, we have tutorials for Java 13 features, news about Java 14 (and beyond!) features, plus the usual mix of tutorials (largely Spring again this month), news, and Other Interesting Articles. Under the latter category, we have a bunch of articles about working remote. This was also a big month for IntelliJ IDEA blog posts, so we’ve summarized those too.

Java News

News this month is a mish-mash of upcoming release stuff, Java-related-company stuff, and conference stuff.

• Some features for Java 14 have been selected already.
• Helpful NullPointerExceptions are in that list — here’s a more detailed look.
• Java Conferences 2020 – here's a pretty comprehensive list of the Java conferences next year. I’ll probably see you at some of them!
• [FOSDEM] [CfP] Free Tools and Editors devroom at FOSDEM 2020 – speaking of which, please submit your talks for the free tools and editors room at FOSDEM, which we’re helping to host.
• Pivoting – analysis of Pivotal’s ownership, how it works, and why things have changed
• Pivotal, Microsoft team up to deliver Azure Spring Cloud
• Microsoft vs. IBM: A major shift in Java support – lots of news in the last few months about Microsoft’s current focus on Java.
• ‘No more room for wars in the new world’? Who are you and what have you done with Microsoft? – Microsoft joins OpenJDK.
• Amazon joins the Java Community Process (JCP) – it’s good to have Amazon on board the JCP, especially since they have their own distribution of OpenJDK.

Culture & Community

I’m always interested in articles about remote working, being a remote worker myself. This month, quite a few of them cropped up.

• Casual Conversation in Remote Teams – I hadn’t even read this article when I instigated peer 1-to-1s in our team for my own personal benefit, I wanted to feel more connected. It’s working.

• On Messing Up Your Remote Team—And Then Getting It Right
• More techniques for making agile games remote-friendly
• Acing the DevRel Interview – or: in which ways are interviews for a developer relations role different from traditional software developer interviews?

• The (Real) 11 Reasons I Don’t Hire You – useful advice for candidates, sure, but excellent advice for interviewers who don’t have a clear idea of what their acceptance criteria are (or should be)
• Scaling Developer Teams: Know-How From Amazon, Facebook, and Intercom – Interview with Rich Archbold (podcast and transcript) – including looking at diversity and inclusion
• If Women Don’t Apply to Your Company, This Is Probably Why – none of these should be a surprise to you by now.

• Developer, Advocate! Tweet it!
• Curiosity as a Service
• Really Know Your Tools

And Finally

A chance to catch up on the other IntelliJ IDEA blog posts from this month. Note that the big thing for us at the moment is the upcoming 2019.3 release.

• Meet Grazie: the ultimate spelling, grammar, and style checker for IntelliJ IDEA
• IntelliJ IDEA 2019.3 EAP5: MongoDB Support and More – all the EAP blog posts are worth reading, but I’m personally very interested in the MongoDB Support (full disclosure: I used to work for MongoDB).
• Introducing Package Search EAP
