You Merely Adopted The Sub Net

Imagine thinking you understand networking because you configured your home router once. Then you meet a sysadmin who's been wrestling with subnet masks since the dial-up era, and suddenly you realize you know NOTHING. They didn't just learn about 255.255.255.0 – they were MOLDED by it, shaped by its binary darkness, calculating network addresses in their sleep while you were still Googling "what is DHCP." By the time you discovered CIDR notation, they were already a master, and subnetting was nothing to them but BLINDING clarity! The dramatic irony here is *chef's kiss* – Bane's mask becomes the subnet mask, the thing that defines their very identity as a network warrior. You merely adopted the subnet; they were BORN in it.

Landlubber Software: The IP Address Whitelisting Saga

Ah, the classic "let's hardcode every single IP address instead of using a regex or CIDR notation" approach. Nothing says "I learned to code from a cereal box" quite like writing 254 if statements when if (ipaddress.startsWith('1.1.1.')) { return 0; } would do the trick. This is the kind of code that makes senior devs develop eye twitches and sudden interests in early retirement.
