TIL: there's an AI merger in @intellijidea.com when having conflicts

If you like the magic wand when fixing merge conflicts, you'll love the AI merger!

After switching from #Windows with #WSL back to #Ubuntu I can only say that the developer experience under #Linux is much better.

Had a blast yesterday at the @jetbrains.com summer party 🥳 And finally got to meet the famous @sebi.io in person ;)

Let's go! @jetbrains.com #summerparty

Updating the #JDK and packing things for the @jetbrains.com summer party. Normal Friday 😁

Ain't that the guy who trained #Batman 😂

just a reminder - there is a #kotlin starter pack maintained by @iamkonstantin.eu

❤️

I had a great first month @jetbrains.com
Onboarding went smoothly, my team is nice and the office is very modern. Looking forward to the next months.

Waiting for #Spring Boot 3.4.1

I just completed "Plutonian Pebbles" - Day 11 - Advent of Code 2024 #AdventOfCode #Kotlin adventofcode.com/2024/day/11
Accidentally implemented 75 * 75 iterations 😅 But at least now I know that the performance is good.

I just completed "Hoof It" - Day 10 - Advent of Code 2024 #AdventOfCode #Kotlin adventofcode.com/2024/day/10
I misread part 1 so that I accidentally solved part 2 in it which I then could re-use for actual part 2 😅

I just completed "Guard Gallivant" - Day 6 - Advent of Code 2024 #AdventOfCode #Kotlin adventofcode.com/2024/day/6
That was unpleasant today 😅

I just completed "Print Queue" - Day 5 - Advent of Code 2024 #AdventOfCode #Kotlin adventofcode.com/2024/day/5
This one made a knot in my brain today 😵

I just completed "Ceres Search" - Day 4 - Advent of Code 2024 #AdventOfCode #Kotlin adventofcode.com/2024/day/4
Strangely, part 2 felt easier than part 1 today

Today got me feeling like:

I just completed "Mull It Over" - Day 3 - Advent of Code 2024 #AdventOfCode #Kotlin adventofcode.com/2024/day/3

I just completed "Red-Nosed Reports" - Day 2 - Advent of Code 2024 #AdventOfCode #Kotlin adventofcode.com/2024/day/2

I just completed "Historian Hysteria" - Day 1 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/1
Same procedure as every year 😁

Kotest + Spring + Testcontainers Recently, I wanted to rewrite a JUnit integration test for my Spring Boot application. Since it was an integration test, I used Testcontainers to start a database. While there are Kotest extensions for Spring and Testcontainers we have the problem th...

With my new blogpost I want to share a simple solution I found while trying to migrate some integration tests to #Kotest. Hope you'll enjoy it!
