KotlinConf Recap: Lessons from Verifone’s Architect on Kotlin in Mission-Critical Payments

Yuri Geronimus’s four-year-old son once asked him what his job was. Yuri told him he writes books: books that describe what he wants to change in the physical world. His son didn’t fully get it.  Neither would most engineers: if you understand the words in your application code, you build good systems. If you don’t, […]

A More Reliable Compilation Scheme for Kotlin Multiplatform Modules

The current compilation approach to Kotlin Multiplatform projects works, but sometimes can lead to unexpected or hard-to-predict behavior. For example: With Kotlin 2.5.0-Beta1, we introduced an optional “separate compilation” approach to KMP that solves both problems: make the compilation results consistent with IDE analysis, and point more consistently to problematic calls of library code from […]
