lnkd.in/p/eXjmAb5c Tickets to this ridiculously good ROI workshop are still available, albeit in short supply. Visit ktconf.be to get yours, for Amanda’s workshop on the 17th of September in Leuven. #kotlin #coroutines

A good teacher creates students who eventually correct them. That is not a failure of teaching. It is its completion.

Evaluating Kotlin for your backend or mobile team? Netflix, Forbes, and McDonald’s already run it in production. You can find the data, case studies, and adoption guidance all in one place https://kotl.in/business-bluesky #Kotlin #KMP

The easiest way to try Kotlin isn’t rewriting your Java app – it’s writing tests. Drop a Kotlin test next to your JUnit/Mockito setup and you’ll immediately see the difference: less noise, more clarity, same JVM. ➡️ Learn more in the Kotlin Adoption Guide: https://jb.gg/kotlin-guide

If you're not sure why, or how to fix it without breaking error isolation, I'll be covering more in-depth scenarios at ktconf.be in a workshop. If your team has lots of hard-to-reproduce bugs, this workshop might be for you ❤️

Kotlin turns 15 🎂 Thank you for being part of the journey. To mark the milestone, we're inviting the community to celebrate Kotlin's birthday. Create a birthday postcard, or upload your photo and party with Kodee. 🎉 Celebrate with us 🎉 https://kotl.in/effect-blog-bluesky

Women belong in tech

Strong opinions, lightly held. That is the recipe for a mind that grows instead of fossilizes.

It's that time of the year! 🎉 The registration for the Open Security Conference 2026 is officially open. 🗓️ 5-8 November 2026 📌 Rückersbach, Germany (close to Frankfurt am Main) ➡️ opensecurityconference.org/conference/r... #osco #osco26 #Security #CyberSecurity #InfoSec #AppSec #OTSecurity [lisi]

Enterprise Kotlin adoption isn’t a language debate. It’s an investment decision. Yuri Geronimus’ playbook shows you how to evaluate Kotlin with business levers like time-to-market, incident cost, audit effort, talent, and modernization risk. 👉 Learn more: https://kotl.in/xbmzv1

An interesting finding from a JetBrains Research study: Kotlin projects appear to maintain development velocity better as codebases grow over time. Readable code, safer APIs, and fewer edge cases compound as backend systems evolve. Learn more 👇 https://kotl.in/r03l60

Once a year, @bejug.bsky.social takes the sessions outside! Hosted by @oniryx.be - @ted.dev : Event Sourcing and the End of DDD Tactical Patterns - @glycin.bsky.social (mis)using Spring Boot to build games RSVP: www.meetup.com/belgian-java...

Built for productivity: what the data finally shows about Kotlin. A JetBrains Research study analyzing 28M development cycles found Kotlin cycles were about 15%–20% shorter than Java cycles on comparable work. Read the blog post to learn more: https://kotl.in/r03l60

My talk alongside @vergauwensimon.bsky.social at #kotlinconf went really well. I hope it was useful for other and future KUG Organizers. Thank you again for this supercool opportunity @kotlinconf.com 💜

CodeRetreat Leuven has started! After the koffiekoeken we did some initial goal setting of the day. #TDD #softwarecrafting #socrates #socratesbe

People that leave the window seat open on the train, who are you and why are you like this?

Soooo, next week's #BEKUG is going to be ABSOLUTE FIRE, because we have Pim van Gurp delivering his talk "TypeSafe Tax Calculations" at DoubleVerify's Ghent offices. Very hyped to see his talk and to see some new people join the community! #kotlin #meetup #openspace www.meetup.com/belgian-kotl...

Soon it's time for the 3rd BEKUG MeetUp of the year! This time at the offices of DoubleVerify in Gent. Our guest speaker is making me nervous haha 😅, but we'll do an OpenSpace for sure. So there'll be plenty of good vibes going on! #kotlin #bekug #meetup www.meetup.com/belgian-kotl...

Today @intellijidea.com 2026.1 is out! We have new AI features, Java 26 support, new Kotlin, Spring and Spring Debugger features, Gradle best practices, Git worktrees and more: youtu.be/FVsMsCFtlOs?...

…being told to write tests[…] is somehow an indictment of their programming skills. So fragile is the ego of many programmers. […] 2026, the same people are suddenly huge fans of the same practices they once dismissed, because now we're talking about verifying some dipshit AI agent's work. 👌👌👌

New article! Did you know #Kotlin has mandatory varargs? ivan.canet.dev/blog/2026/03...

Vote for me lol

Who should receive a Golden Kodee? Now’s your chance to show support for the community members who inspire, build, and help others. Vote for your favorites! https://kotl.in/6zi8k8

⏰ Only 1 week left to sign up for Gien's workshop on Strategic DDD. In this training, we'll guide you through the DDD starter modelling process, providing you with a structured process and new visualisation tools for your toolbox to explore and identify bounded contexts: buff.ly/ud2Wuxl

Looking forward to see you at @kotlinconf.com 2026 with my new talk « Idiomatic Kotlin applications with Spring Boot 4 » where I will share all my related recipes and guidelines. #spring #kotlin kotlinconf.com/speakers/ce1...

Key to efficient learning is realizing how we ACTUALLY learn, not just what FEELS like learning. I wrote a Claude Skill for some friends to help them think about this and they've liked it -- see Principles for some directions you could explore github.com/DrCatHicks/l...

This Thursday is the first Belgian #Kotlin Meetup of this year @ DPG Media! 8 spots left! Devs DPG will share how they have adopted #KMP in their iOS and Android apps, and after we’ll have an open space & networking event. It’s going to be super fun. www.meetup.com/belgian-kotl...

Came back to the office after quite a while to find this on my desk 😍 @kotlinlang.org #kodee

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...

Teaching Kotlin at a university or in your company? We've put together a complete 'Teach Programming With Kotlin' toolkit – slides with speaker notes, a syllabus, quizzes, homework assignments, tests, and hands‑on projects. Use it as‑is or adapt it: https://kotlinlang.org/education/

🚀 Build dynamic web apps without the SPA overhead! Anders Sveen shows how the combination of HTMX, Ktor, and kotlinx.html can simplify full-stack Kotlin. A must-watch! https://kotl.in/7stxd6

In 2 weeks we’re kicking off the Belgium @kotlinlang.org User Group with @sch3lp.bsky.social! The first session since 2019 😍 We’re starting off with a talk, and afterwards we’ll have an open space. There’ll will be lots of Kotlin and Kodee goodies 😁 See you there! www.meetup.com/belgian-kotl...

blog.jetbrains.com/kotlin/2025/... great blog post that proves why moving to Kotlin is a good choice. @jlengrand.bsky.social and I can vouch for that 😉

🤔 Curious about Kotlin but worried about rewriting your Java code? No need – Kotlin and Java work seamlessly in the same Spring project. Start with a single service and expand from there. Check out our updated tutorial 👇 https://kotl.in/rzdau2

📢 Rare opportunity: my team is hiring! We're looking for a new Developer Advocate to cover server-side Kotlin, focusing on Spring. If you love Spring, Kotlin, and their communities, this might just be for you. Learn more and apply here:

I've written a small blog post about how context parameters change API design in Kotlin serranofp.com/blog/context... Feedback and discussion is more than welcome!

That’s a wrap for day one of #SocratesBE Here’s a FOMO inducing photo of today’s marketplace. What you don’t see is Vincent’s legendary lightning talk on Limburgse Vlaai. That happened Thursday evening already.

1/ Experiments are useful to learn what's possible, to discover your blind spots, to generate optionality (aka the availability of options even when you don't need them), and to allow innovation. Without experimentation for the sake of discovery, there's no science, art, philosophy.

i wrote about atproto and why it matters

Too bad there isn’t an action shot of @serranofp.com acting out a Venn diagram with his entire body to explain Union Types. #NeverForget 😉❤️

I had an amazing time connecting with everyone at KtKonf! And Looking forward to building a stronger Kotlin community in Belgium together. Special shout out to @sch3lp.bsky.social for taking the initiative, and everyone for making this happen ❤️ Hope to see you all again soon!
