That's One Way To Remember It

Someone made a brutally honest HTTP status code cheat sheet that cuts through all the technical jargon. 1xx means "hold on, still processing." 2xx is the good stuff - "here you go, your request worked." 3xx tells you to "go away" (but politely redirects you elsewhere). Then we get to the fun part: 4xx is "you fucked up" (client errors like 404), and 5xx is "I fucked up" (server errors like 500).

The presenter clearly knows their audience - developers who've spent way too much time debugging API calls and staring at status codes. Why memorize boring RFC documentation when you can just remember who's to blame? It's the most practical mnemonic device since "righty tighty, lefty loosey."
