Programming a programming language sounds odd, weβre used to programming with one, not building it. But after watching this, I must say working on @kotlinlang.org must be pretty cool. In the end, youβre building a product exclusively for devsβ¦ and now for AI agents π.

I wrote a piece for the trivago Tech Blog about how mob programming can turn a team into⦠well, an actual team.
If you're into collaboration, dev culture, or just curious:
Meta Quest Store saw 12% faster loads & 2.5Γ faster interactions with #React Compiler. ESLint and React violations looks solid too
I'm skeptical, but definitely going to try it out. Auto-memoization without manual useMemo/useCallback sounds promising.

In big codebases, duplicate logic hides everywhere, especially when you are new to a project. AI can now help us spot and prevent those clones before they grow into tech debt.
In the age of #AI and AI-powered IDEs, we should get used to asking questions like:
π βIs there a function that already does this?β
π βWhich part of the code handles that?β
π βDid I just duplicate something?β
Kernel Panic!
#linux is a sponsor of my evening plans!
I was excited to discover #Redis numbered databases⦠only to learn the same day they are widely considered a mistake. I wonder if anyone is actually using them in production
Munich it is then! ;)
Out of curiosity, I ran some offline LLMs on my Raspberry Pi 4. Building from source was fun, and watching it struggle to squeeze out a word per second, even with the smallest models, was oddly satisfying. It met my low expectations perfectly π
#raspberrypi #llm
Just watched @gergely.pragmaticengineer.comβs βSoftware engineering with LLMs in 2025: reality check.β Clear, grounded look at how AI-coding tools are used day-to-day. Loved the four wrap-up questions!

For some reason the gif is just an image :( @bsky.app
GIF recorded in IntelliJ Kotlin Notebook. A kaomoji face slides left-to-right and back, driven by a Kotlin ANIMATE(0.2.toDuration()) block that updates the output every 200 ms
π Tried Kotlin Notebookβs `ANIMATE {}` today and got totally sucked in.
First plan: shiny data plots.
Actual result: a roaming kaomoji ( Ν‘~ βΏ Ν‘~)
Bottom line: with a bit of code, #kotlin notebooks move more than just data.
3 years in a row, I attended @kotlinconf.com, always inspired by the quality and the community. This year, I had the privilege of speaking there myself.

Also happy that I got to bring deltaration.com to the spotlight π

Wrote short article about use of Koog for developing Kotlin based AI agents (combined with a number of MCP servers).
The example included is based on use of #BuildWithGemini LLM (really had to use that with #GoogleIOConnect fast approaching π) johnoreilly.dev/posts/kotlin...
It does not seem this way when adding bools, but when an extra value has to be added to boolean, I want to go back in time
A quick reminder. We all know not to click links on emails from unknown sources. Spam is an unknown source. The "unsubscribe" link is a link from an unknown source. Even a "known" sender can be spoofed. Just send it to Spam (or at least thoroughly vet the URL before clicking). Just sayin'.
Had an inspiring two-day exchange with the #trivago tech crew in the Netherlands! π
Huge thanks for letting me join the lineup.
Special thanks to everyone who packed the room for βMob Programming: Smells Like Team Spirit.β ππ₯ Your questions and hallway chats were the best part.
And if you by chance have the same problem, test out my fix, hope it saves you some time: askubuntu.com/a/1549957/22... 8/8
Tiny story, big win: Embrace the inconvenience, let it challenge you! And donβt forget to take those vacations (or workations) whenever you can. 7/8
I ran the final steps on the work laptop, boom, camera alive on the first try πΈβ . Today, everyone can see me andβ¦ how unlucky I am with the weather πβοΈ. 6/8
So last night I dove into three-and-a-half hours of Googling, installing, purging, rebooting π§βπ», chatting with GPT, rinse, repeat. Just when I was about to give up, I opened Google Meet and saw my bleary face staring back. Victory! π 5/8
Then I headed off on a workation π΄π». I forgot to pack an external cam, figured Iβd surviveβ¦ until I saw my calendar packed with meetings and an interview. 4/8
Iβve never been short of options: thereβs an external webcam in my home office and another one (plus plenty of Zoom rooms) at work, so the missing laptop cams never felt urgent. I poked at the problem now and then, got nowhere, and shrugged it off π€·. 3/8
Fast-forward to Ubuntu 24.04: upgrade done, webcam dead again π. Same fix, no luck. Then trivago handed me another Dell for work, and yes, its camera was also playing dead π. 2/8
I picked up a Dell in October 2022, installed Ubuntu 22.04 on it, and, surprise! The built-in camera was a no-show π·. After some digging, I found a workaround and moved on. 1/8
Always wanted to build a personal website but never found the time. Gave #Junie by @jetbrains.com a try, and Iβm genuinely impressed with what I could put together so quickly. If it wasn't for Junie, my domain would still be collecting dust: kurets.dev
It is great how many trivago people made it to @kotlinconf.com!
