Waiting for Gradle to finish 😂

Today @ogkodee.bsky.social tried telling Slonik but I'm not sure it understood

I found a HACK to get EVERYONE to TAKE PICTURES OF ME at TECH CONFERENCES You wouldn't guess what it is

I'm trying very hard to materialize an Exposed mascot @ogkodee.bsky.social

FOSDEM 2026, Here we go!

If I had a nickel every time I visited a french-speaking capital city on a river named ‘sane’...

First cultural shock in Belgium: 5.50€ for water in a restaurant??

Thursday 12/02 we’re hosting the first BEKUG MeetUp of 2026 at DPGMedia in Vilvoorde! Interested or curious about @kotlinlang.org ? Register for free: meetu.ps/e/PNbwy/sYjb...

What did I do again 😅

I have to ensure 3 different serialization libraries have the same output, and of course, they don't 🤦‍♂️ • the MongoDB data-class serializer • the MongoDB KxS serializer • my own KxS serializer

It turns out, I'm very good at crashing the Kotlin compiler

Yeah I was wondering how long it would take to learn how to avoid explicit user authorization

RIP Gwen, 2012–2026 ♥️

Super de faire un changement à St Pierre des Corps. Dans un rayon de 20min à pieds il y a en tout UN kebab, et le mec fume en cuisine

Big companies investing into New Things is good! Stop hoarding! But everyone could see it wouldn't work when a budget larger than some countries' couldn't copy the existing tech of VRChat. Where did the money go?

Bordeaux, France

Shit is getting bad out in the actual software economy. Cash registers that have to be rebooted twice a day. Inventory systems that randomly drop orders. Claims forms filled with clearly “AI”-sourced half-finished localisation strings. I see more and more in the lives of people around me every day.

Implementing JSONPath is interesting It looks like $['foo']['bar'] Or, simplified: $.foo.bar Essentially, it's composed of segments. Each segment is a filter on the matching ‘depth’.

Finally got around to finishing it! Thanks @mbonnin.net

New page: all the conferences I've been to (and some of the future ones too) …I'm actually surprised it's that much. 2025 was busy, and that doesn't even include the BordeauxKt events I hosted. ivan.canet.dev/talks

Looks like I'll be there too—let's meet in the Kotlin room!

I love a good UI rant, and this one brought receipts

Nice! git-wrapped.com/profiles/clo...

I'm fascinated by the amount of stuff (especially foods) that are common commodities nowadays but were near-unobtainable recently. Mirrors? Three hundred years ago, you had to be crazy rich. Who was the first western European monarch to taste smoked salmon? How expensive was it?

Even the IDE has had enough

I'm implementing JSONPath for KtMongo and I see that there multiple existing implementations for different data structures. I think I can scale mine so users could make it work on their own stuff I may explore that once I'm done with the BSON impl

Typical day. Started having some fun writing some code, and then got hit but this Now I'm trying to reproduce it in the Playground and… it doesn't want to be reproduced

Today I'm working on extending Pedestal's support for multiplatform weak references... What about you?

LOOK AT HIM

Reading low-level code is always fun (from AtomicLong in the JDK)

Ah

What should the DSL for GitLab's workflow:rules should look like? 👀 Should I let the `if` be a string? Or introduce operators?

Damn, that many?

oops, I broke it

New @kotlinlang.org language proposal: companion blocks and extensions github.com/Kotlin/KEEP/... Feedback is more than welcome!

For such a major change on the compilation model, it's noteworthy how trivial the syntax change is Personally I find that to be a marker of a great language feature: lots of new opportunities, solves many problems, but very little impact on learners

Just like many specifications, RFC 9535 (JSONPath) is very easy to implement at the start, and then you realize it's actually turing-complete

This code is not ambiguous

Vite for Kotlin 0.7.0 is out! You can now use #vite 8 in your #kotlin projects, with experimental WasmJS support and important bug fixes! vite-kotlin.opensavvy.dev/news/2025/12...

Schema-first or code-first?

Meet me at #APIDays near the API Standards stand!

I'm always surprised by how many people don't know about the Kotlin Slack community. It's a fantastic place to discuss issues with others, with dedicated channels for almost any Kotlin topic, and lots of JetBrains people monitoring them too.

Ok but… why? Why forbid the init block and introduce a new 'compact constructor' syntax which does (as far as I can tell) the same thing? I initially thought it was an execution order thing, but no, they're both executed before the real constructor body

I *just* got Vite 7 to work in the Gradle plugin 😅

Java having records and sealed interfaces, but them being incompatible with each other, is SUCH a missed opportunity

now that's a fun one iwriteaboutcode.blogspot.com/2025/11/afte...

ouch pl.kotl.in/EJCxXPFMZ

Thanks, Google Why does it index a random GitLab issue with no activity faster than my blog posts? 😢

Wait that's a UX option? No one ever told me
