A light‑hearted rant about why a plain‑old mutex is the hero of secure C/C++ concurrency, why goto is still secretly useful, and how to keep your locks short and your bugs shorter.

A dive into a custom ISA for RSA: modular‑instruction shortcuts, multiply‑subtract tricks, and exponentiation‑by‑squaring hacks that shave a few cycles off the dreaded big‑number math.

A breezy, slightly tongue‑in‑cheek look at why setting pointers to NULL right after free (and a few related memory‑management niceties) can save you from nasty use‑after‑free bugs, memory leaks, and the occasional midnight debugging panic.

The sequel to the null‑termination saga, now tackling strcat, strncat, strlcat, and friends—plus a quick table to keep your concatenations from turning into catastrophes.

A light‑hearted reminder that every character buffer deserves a '\0'—otherwise you’re inviting buffer overflows, stray reads, and a lot of debugging grief.
