#neotype for #Scala3 by @kitlangton is an absolute gem of a library, combining together the power of new types and refinement types. Absolutely recommended, if you don't use it yet.

Next chapter in that high-performance #Scala game server. A while back, there was an article about rebasing the core logic processor (purely functional, no IO, no concurrency, bottlenecked on CPU and heap allocations) from #ZIO to ZPure for performance reasons. Now taking it a step further with replacing ZPure with PureLogic (written for this purpose). Uses #Scala3 context functions and "direct style" instead of monads, greatly reducing the number of allocations.

Introducing PureLogic: direct-style, pure domain logic for Scala

PureLogic is a new Scala 3 library for writing pure domain logic using direct style instead of monads. It provides 4 capabilities (Reader, Writer, State, Abort) that compose naturally through context functions, with zero dependencies and 7-40x better performance than monadic alternatives.

Every couple of months I give #ScalaCLI / metals / vscode / #scala3 a spin for side projects ($DAY_JOB is still #sbt / IntelliJ / 2.13 ).

It is coming along nicely.

Ah yes, Scala 3: the new scapegoat for rushed migrations by our fearless developer who never met a dependency he couldn't blame. 🚀💾 But fear not, the absence of "macro wizardry" is clearly the culprit for his inefficiencies, not the compiler he swears by. 🧙‍♂️🔮

Scala 3 slowed us down?

Is this clickbait? Not really. Is this the fault of the language or the compiler? Definitely not. Rather, it was part of a rushed migration. Sharing the lessons learned in the process.

Oh… So #Scala3 is basically #Python on JVM? 🤔
