@tagir_valeev @danieldietrich @lukaseder 4 years later: I feel kind of surprised that I failed to see what you saw (esp. how it violated KISS) 😮
Now I try to focus on specific goals, like having contract tests. So when I missed a good DSL for Pact, I built one: https://t.co/R41ajRxhxG (took 3 weeks)
Looks readable? 🙂

Hey @danieldietrich @lukaseder @tagir_valeev, may I ask your feedback as library maintainers?

Would you consider the idea below useful, esp. for #JDK8 libraries that need immutable Collections?

💡 Facade of #JDK9 Collection factory methods, e.g. List.of

https://t.co/uR6arRHsfp

[@tlinkowski.pl 🦋 @t_linkowski]

My new library, UniJ, is ready! 🎉

#UniJ is a #JDK8 facade for #JDK9+ API 🙂

Analogy: UniJ is to JDK 9+ API what #SLF4J is to logging API.

Example:
> List.of(1, 2) // on JDK 9+
> UniLists.of(1, 2) // on JDK 8 with UniJ

If you like it, please share! 🙏

@javarevisited I need a stream to collect a list

Many of the software engineers I talked to told me that they practice TDD out of guilt.

That's not right, we need a different way to think about TDD.

I've been practising TDD for almost a decade, here's how I currently think about it:

[Roman Elizarov @relizarov]

I'm happy to see one more language adopting structured concurrency. Interesting design tradeoff, though. In Kotlin it is purely a library feature, while Swift plans to integrate structured concurrency directly into the language with `async let` syntax. https://t.co/yQycfq5e4N

[@tlinkowski.pl 🦋 @t_linkowski]

@nipafx Just FYI, I tried to coin terms "reducePartially" (for T->T) & "reducingMap" (T->U), then renamed to "chunkedReduce" for both (but it never got accepted).

To me, the operation you mentioned is such a chunked/batch/partial/(pick your adjective) reduction.

No matter paradigm, to be successful hide the “how” and make “what” explicit.

But each paradigm has it’s own ways to do it.

@bmuschko Kotlin: static typing and static analysis → "clickability" in IntelliJ

[Jakub Kozłowski @kubukoz]

Still hiring. Let me know if you're interested!

[@tlinkowski.pl 🦋 @t_linkowski]

@codeJENNerator I found out late, but it's sad news. Good luck, Jenn!

[@tlinkowski.pl 🦋 @t_linkowski]

@tagir_valeev @olegchir What you wrote as an explanation made perfect sense to me 🙂 So I wouldn't expect any kind of shitstorm (but maybe I don't know the Internet well enough).

PSA: I'm happy to announce that, in a week, I'm changing jobs. After 7 years at LangMedia, I'm joining @OcadoTechnology as a #Java Software Engineer 😀

@pivovarit That's some very serious competition! 🙂 But it might not be SO bad about your audience - there are certainly people that are not interested in either Kotlin nor reactive, I guess... Good luck! 🤞

[Andres Almiray @aalmiray]

Are you a long time Apache Maven user but have to deal with Gradle? Do you find Gradle to be confusing, irritating, or difficult?

Then there’s an option for you

https://t.co/TWpLWkJwNV

Bring your Gradle builds back to sanity.

[@tlinkowski.pl 🦋 @t_linkowski]

@philipp_hauer Something else: Spock.

Unfortunately, testing Kotlin code using Groovy has quite a few quirks (like verbose access to objects, internal types, & extension methods).

You can optimise for low latency.
You can optimise for high throughput.
You can optimise for memory occupation.

However 90% of times the most precious thing you should optimise for is maintainability.

@CedricChampeau Interesting 🤔 I, on the other hand, like it very much...

Thanks to it, I don't have to think about formatting that much, especially about indents ("Reformat Code" in #IntelliJ does it for me).

What can software developers learn from board game development? Maybe they aren't such different skills! https://t.co/H7bV7Twfkv

@nicolas_frankel @piotrprz That would take some time - there's over 400 of them 😊

@aalmiray And what's wrong with them? 🤔

[Márton Braun (write-only account) @zsmb13]

Here's a not-really-technical post for a change, where I ramble about imposter syndrome.
