Language + libraries count as a separate language In the header of your entry, you should have something like this: C (clang) + <libraries>, <byte count> You do not need to inclu...
How should we deal with golfing libraries when scoring entries? Continuation of Is my extension-like library allowed to be used in answers?, the answer to that question seems to be a "yes", now we...
I say we follow the established rules on SE: Rather than dealing with inconsistent schemes for adding flags, let's just consider each separate invocation of a compiler/interpreter/whatever a sep...
How should we deal with flags / command line options when scoring entries?
About Negabinary Negabinary means base negative two (-2). That is, the $n$th place value is determined by $(-2)^n$. Negabinary numbers can be evaluated just like any other base system. For exampl...
