Rui CarmoA great systems-oriented programming language I’ve taken up to complement Python due to its ability to cross-compile and produce (mostly) self-contained static binaries.
Tricks
Shrinking executables via gccgo and upx:
go build -mod=vendor -gccgoflags '-Os -s' -o main && upx --best --lzma main
