at least existing features and data remain free.

For now.

LibreWolf

Wayland has at least one deal breaker for me. It doesn’t remember where my windows were at logout when saving the session. I have six virtual desktops and have specific windows in certain desktops. Putting everything back where they belong after each login, no thank you. Until they add that I’ll stick to X11.

I’ll add shift + f6 for refactor rename and ctrl + 6 for redefining your function i.e. add/remove parameters and/or return value.

I use Jetbrains’ products for all my coding needs.

If this is supposed to be a comparison for Kotlin developers why are all the Spring Boot examples in Java instead of Kotlin?

The whole article also is more of a what Ktor is and why it’s better instead of actually comparing the two.

Learn Groovy

Stay away from Groovy. It’s a horrible language. It’s quick to write but slow and difficult to read. It’s conventions make it a very error prone.

Link to the things you mention e.g. you say to get familiar with Loom. When searching for that all I get is some screen recording software (probably not what you meant).

Scala pays better than Java or Kotlin

According to what research?

Nice list.

Some comments

• If you’re just starting to develop something you don’t need multiple versions of JDK. Just use the latest LTS version (v. 21 currently).
• Git is always good to have. IntelliJ IDEA has a built in git client so others aren’t strictly needed at first
• Ultimate version of IDEA (paid software) has full support for Spring (inc. Spring initializer)
• If you run Linux podman is a good choice instead of Docker
• For plugins I’d add sonarlint (helps with code quality)
• I’d also add Spotless to the project for automatic formatting
