sed/regex Based BrainFuck Compiler

BrainFuck is an ‘esoteric’ programming language with only 8 one-character instructions. I’ve used it here-and-there for well over a decade. I love minimalist languages, so RISCy. A brainfuck environment operates on a large array of data. There’s an instruction to move the pointer in this array forwards and backwards and to increment or decrement it’s […]


Assembly is Too High Level: Commutative Property, Sometimes (it may save your byte)

I remember learning these properties in basic algebra: Associative, Distributive, and Commutative. It’s the Commutative property that states that a + b = b + a. The same principle is true with multiplication. In x86 pointer math, of course the results of these operations follow the commutative property; that’s just math. However, the machine encoding […]
