Lately I’m writing C++. I have code that needs to deploy across different mobile ecosystems. Java doesn’t cut it, Kotlin has a cross language offering but it’s not prod ready, and Rust... well, the team doesn’t know Rust and we won’t hit our dates if we have to learn idiomatic Rust, and once we ship the code, it won’t be as simple getting some customers updates as we have customers in the wilderness and these aren’t iOS or Android devices that we can just release to using app stores.

Despite Java’s verboseness and all the factory hell, with recent tooling and the massive library of great open source libraries, I do enjoy writing it. I prefer strong typing personally. But I don’t agree with Java for everything. Recently I did some data processing work on Spark. I wrote everything in Scala. The whole “trait” functionality was very nice and elegant, and it allowed me to incrementally build some nice abstractions that my team can use to quickly build and deploy spark jobs.
