My kind of weekend procrastination: coding with JetBrains Junie (and other AI agents). This time, tried figuring out how it works for Compose Multiplatform projects with Kotlin.

Testing the AI coding agent capabilities with C++ and JUCE framework: a simple app to visualize MIDI and play synth waveforms. Nice! As JetBrains Junie is now available in Clion, I can now build some cool things I wasn't able to do before.
