Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

status flags

A few single bits the processor sets after an operation to describe the result - was it zero, negative, did it carry, did it overflow.

Status flags are one-bit condition indicators written by arithmetic and logic instructions and read by conditional instructions; x86-64 keeps ZF, SF, CF and OF (among others) in RFLAGS, ARM64 keeps N, Z, C and V in NZCV, and RISC-V has none.
