Hi all! At the Kotlin Ecosystem Committee, we are...

# kotlinconf

[Oleg Nenashev]

Hi all! At the Kotlin Ecosystem Committee, we are exploring the options of hosting an additional community demo session during Kotlinconf 2025.

This entails ~2 hours of short 10 minute demos that will be open for sign up before the conference and even during the first day of it. Any conference participant will be welcome to propose demos of various Kotlin focused tools and libraries they've created or are working on. It somewhat counts as KotlinRejekts, too ;)

Just to measure the interest, Is there anyone potentially interested in doing such demos? Do not hesitate to propose your ideas in the comments

I can demo a Kotlin DSL for MongoDB

The http4k team would love to show off the ModelContextProtocol SDK that we've been working on 🙂 (being released today)

[Bernd Prünster]

We'd love to show off any of the following:
• Signum - A KMP Cryptography library with tight platform integration, including native biometric auth and attestation support
• VC-K - An EU Digital Identity Wallet library covering the full stack from issuing, to presentation and verification, including remote signature and a variety of verifiable credentials, successfully interoperating with the EU reference implementation, but developed 100% independently in pure Kotlin
• Valera - A CMP EU Digital Identity Wallet app, based on the above
(all projects are open source)

I definitely love the idea, and IMHO it should also be „allowed“ if somebody has an idea without a demo and wants to pitch it/discussed it with the community.

The conference should not be only about (recorded) sessions, but about connecting people.

Love the idea. Depends how many application you get but 10min is a bit long IMO. I'd rather have 50 x 2min demos than 10 x 10min demos.

[mbonnin]

Maybe 10min is good for a demo, 2min is more of a "pitch" I guess. Depends how you want to frame it.

[dave]

Maybe 5 min - but definitely > 2. You want people to be able to at least gather their thoughts a bit. 🙃

[mbonnin]

I do too much Tik Tok videos these days 🙈

[Oliver.O]

I'd love to demo and get feedback on what a lightweight, coroutines-first, 100% KMP test framework could look like. Including some Q&A, 10 minutes would be the right time frame.

I am definitely +1 too. Hopefully, next year we could do a full-fledged Kotlin Contributor Summit 🙂 🙏

This is why this thread is started 🙂 The format is to be adjusted based on the interest and the availability of the rooms/timeslots/hosts

full-fledged Kotlin Contributor Summit

Like a hackathon?

[Oleg Nenashev]

In Jenkins we're used to doing 1-day contributor summits before major community events like FOSDEM or Jenkins World (RIP). Such events normally I got there from 50 to 100 maintainers and contributors, and they become a kind of general assembly and unconference, where the developers just discuss the community and architecture focused topics.

And yes, it is often combined with a multi-day hackathon where some cool stuff gets developed in collaboration. I'm not sure if it's still within the topic of this thread, but we can definitely discuss such ideas in a separate thread though it is late for May 2025.

[CLOVIS]

Since JetBrains already pays for the venue on the workshop day, and workshops tend to be introductions (that library authors probably already know about), it could be an interesting idea to have a ‘library author's day’ or half-day during the workshops where we meet up and just discuss / brainstorm ideas. (And here by ‘library authors’ I mean ‘anyone who is interested in contributing to the ecosystem’). 👀

Let's detach a bigger event discussion to https://kotlinlang.slack.com/archives/C4J6927RR/p1743266844591889?thread_ts=1743266844.591889&cid=C4J6927RR
