@vergauwen_simon True, supporting every use case in a logging library is almost impossible, there are a lot of sacrifices along the way. So, yes, maybe, we don’t need standard logging library at all? :)

@why_oleg Great point. The answer is maybe ego? Or trust? On the other hand it is also so low effort to write a logging library it is almost easier to build your own than to contribute to someone else's and wait for review, merge and release. (+ dopamine and sense of accomplishment).

Why does everyone wants to create a logging library? I mean, I’ve seen more than 50 Kotlin libraries, most of them doing roughly the same… There is even four libraries with ~+1000 stars! And still, every month in a while one more is created And still, there is no default choice

@vergauwen_simon Yeah, yeah. Still, why not to contribute instead of creating new one? That’s what I can’t understand…

@why_oleg > And still, there is no default choice That's exactly the reason why people keep creating them. The community needs/wants a default...

@sur3shg I’m curious, why do you think that logging should be first party? Not every popular/modern language/ecosystem has first party logging API, or, even could have one, but no one will use it (hello Java)

@why_oleg And there still isn't a single good logging library for Kotlin Native that's comparable to Logback ( file rotation, backups, the basics). IMO, logging is pretty foundational, and I still have hope for kotlinx-logging from the Kotlin team 🙂

See for yourself: klibs.io/?tags=logging Should we (as a community) do something about it? Of course, I’m not against creating new libraries, but do you think that all this enthusiasm could be redirected to other, less developed categories?

@why_oleg Can we use the decentralized model to support you?x.com/Pumpfun/status… ?

🚀cryptography-kotlin 0.6.0 is here🚀 - More algorithms, including EdDSA and ChaChaPoly - New website with a lot of new content - Improved CryptoKit/Swift/Xcode compatibility - New API to get a public key from a private key - JWK encoding in all providers github.com/whyoleg/crypto…

Thanks to everyone who uses and contributes to the project - it truly means a lot ❤️ If you or your company rely on the library, consider supporting its development. This helps keep it maintained and evolving. github.com/sponsors/whyol…

But the most exciting part isn’t the release itself, it’s the people who use and contribute to the library! Recently, I collected statistics on algorithm usage and was impressed by the number of projects and the variety of use cases! gist.github.com/whyoleg/ce750b…
