C99 on Linux and Windows.

Kotlin vs Scala a novice comparison

A dissatisfaction with the Kotlin compiler (seemingly you can’t compile inter dependent sources on their own…) lead me to have a quick look at other JVM alternatives.  Scala is a project which by now is mature and stable, its also had significant financial backing from a number of sources, which at least gives you the… Read More »
