It’s only two weeks since the last Java Annotated Monthly and we have another huge issue! I’d like to say March’s edition is dedicated to International Women’s Day, and it can be if you like. To be honest, the inclusion of women contributors in this month’s newsletter is, in fact, nothing special or new. It’s the result of several years of hard work identifying new sources of videos and articles, intentionally expanding the people I follow on Twitter, and placing effort into amplifying voices that deserve to be heard. There is still plenty of room for improvement though so I will not relax and say “it’s OK, we’re diverse now”. Because we’re not.

Devnexus 2020 Interviews (video) – some of my favourite people appear here
Java is not Dead (podcast) – featuring me, Trisha Gee! In which I cover some of the latest changes in the Java ecosystem. Shouldn’t be much new in here for you regular readers since it’s all stuff I’ve linked to from Annotated Monthly

Ghostcat breach affects all Tomcat versions – update Tomcat now!
THREAD: Background and explanation for deprecation of the java.lang.Object constructor.
This work is in the Valhalla prototype repo, not the JDK mainline. What eventually arrives in the mainline will likely differ. Existing code will continue working or have a migration path. 1/187
Java Tutorials & Tips
Why is map called map? – honestly, this was one of the most confusing things to me about the move to the more “readable” Streams API
A new Swing Look and Feel I have been working on – Swing isn’t dead!
Make Code Simple and Readable – this stuff is “obvious”, which means read it to remind yourself and then share it with the team
Serializing Records – I think records is my favourite (preview) feature from Java 14
Making Space for Pattern Matching – another nice new preview feature from Java 14
Languages, Frameworks, Libraries, and Technologies
- BDD is not Test Automation – agreed. I’ve seen this incorrect focus cause issues plenty of times.
5 ways to drive your automation engineers away – “It’s hard enough to find great programmers or great testers, and it’s even harder to find people who are both. Don’t let these valuable people get away”
Easy Boarding with Kotlin and PCF – a follow on from the above
Kotlin and Domain-Driven Design—Value Objects – some of the points in here are helpful to understanding upcoming changes in Java (records, inline classes etc)
Nine Ways to Fail At Cloud Native – failure is a much better teacher than success. Best if you learn from someone else’s failures
Multi-Runtime Microservices Architecture – I… don’t know what this means. But it looks like something you should read if your job description includes the word “architect.”

I am a senior developer, Katie. I still say these things. https://twitter.com/katiefujihara/status/1233560256493621248 …katie @KatieFujihara
Hi, I'm a junior software engineer. You might know me from my hits "sorry, I have a question," "sorry if this is a silly question, " "sorry if I asked this before, " and the chart topping "sorry to bother you again." https://twitter.com/kurtkemple/status/1233559380823592960 …
Culture & Community
Happy International Women’s Day (March 8th)! And because someone is bound to ask, November 19.
Also, this section just keeps getting bigger. This month I’ve included a bunch of books, too, as I’ve been reading more actual paper things in the last year or so and, who knew, I’m learning a lot from them.
Sometimes I consider re-focusing the newsletter on just Java-specific stuff. I do not want to do this. I believe developers are people first and a language-typist second. Or third. Or maybe even waaaay down the list.
- This is your semi-regular reminder to read Programmed Inequality.
- Susan Fowler: Why I Wrote the Uber Memo – making the decision to speak up is not something one takes lightly
Read Susan Fowler’s book.
Joining Blameless – the point of the post is about a specific job move, but the majority is highlighting how it sometimes (often?) feels working in this industry.
- Being Glue – This was mentioned in the previous blog. Recommended reading.
These Women Entrepreneurs Created A Fake Male Cofounder To Dodge Startup Sexism – surprised? No. Sad? Yes.
“Culture Fit” is Code for Biased Hiring – read this
Why Diverse Teams Are Smarter – a reminder
Diversity, actually – Ronna Steinberg – looking at how to change/update hiring processes to improve diversity (specifically gender)
Lambda School’s Misleading Promises – boot camps should help “close the skills-gap”, but articles like this suggest some organisations may be damaging, particularly for those from under-represented groups and other at-risk people.
- HackerRank: Coding bootcamps explode in popularity among younger developers
Collaborative Overload – “As people become known for being both capable and willing to help, they are drawn into projects and roles of growing importance.” and “…the evidence shows, women experience greater emotional exhaustion than men.” and “In an experiment… a man who stayed late to help colleagues earned 14% higher ratings than a woman who did the same. When neither helped, the woman was rated 12% lower than the man.” This article shined a light on a lot of patterns and behaviours I’ve seen.
- I’ve just finished Daniel Pink’s book When, some of the ideas in that have helped me with the above overload issue, and also helped me to design my working week a little better.
“How to win friends and influence people” book review – pulls out some lessons from the book that might apply to us
CodeNode Relaunched by Trifork – London-based techies may be pleased to hear this, but I’m still very sad about the demise of Skillsmatter
The cumulative cost of additional wakefulness: dose-response effects on neurobehavioral functions and sleep physiology from chronic sleep restriction and total sleep deprivation – “Chronic restriction of sleep to 6 hours or less per night produced cognitive performance deficits equivalent to up to 2 nights of total sleep deprivation.” All parents already know this.
Your Realistic Guide To Beating Burnout (Because A Vacation Isn’t The Answer) – ”Maybe it means coming up with an end-of-day routine…that helps you transition from “work mode” to your personal life.” – I’ve been trying this for only a couple of weeks (it’s particularly hard to separate from work when you work from home) and it has made a noticeable difference.
Finding a creative hobby will make you a better software architect – write up of a conference talk
What Is Your Professional Love Language? – I recently found out about “Love Language” and it’s an interesting thing to understand in the context of work
Please Stop Calling them ‘Soft Skills’ – loved this idea of rephrasing to “behaviors” and “tools”
Quantum computers could be the ultimate defence against the next global financial crisis – mmmm, because faster computers don’t do stupid things quicker…
- Alexis Coe on Why It Matters When Women Write History – not an article about technology, but interesting all the same
Katherine Johnson Dies at 101; Mathematician Broke Barriers at NASA – note: I highly recommend reading Hidden Figures.
Pluto was discovered 90 years ago this week. Controversy about its identity rages on – speaking of space stuff
“The erasure of Williams’ work is also a reminder of the ways that women have been excised from the story of the history of science. ‘Even though they were in the shadows,’ Clark said, ‘[women] were contributing to this field.'”
A chance to catch up on the other IntelliJ IDEA and JetBrains blog posts from this month.

- .NET Annotated Monthly | March 2020 – .NET? Really? Yes really! My colleague Rachel Appel does a great job of the .NET newsletter. Like this one, there are things in there that apply to all developers.
We are hiring!! I’m looking for a Java/JVM Developer Advocate to join my team. I’m interested in talking to developers who are thinking of switching into an advocacy career, i.e. you don’t need to be an experienced speaker/blogger to apply.
