The craziest thing about modern life: You can spend 8 hours working just to afford things that help you recover from the 8 hours you spent working.

RT @straceX: 96% of Github repos in 2026 be like:😂

You click “Download.” the progress bar jumps to 90% instantly… then sits there for two minutes. Your internet speed can change every second, so how does it know the progress that fast, or does it fake it?🤔

The most terrifying milestone of adulthood isn't paying your first mortgage. It’s the sudden, quiet realization that there are no actual adults in charge the entire world is just running on the panicked improvisation of people who are pretending to know what they are doing.

@chizhao 🥲

As a developer, have you ever wondered: You type a 16‑digit card number and the form instantly says “Invalid card number”. There are billions of possible numbers. How the hell is that check that fast?

@Celsius233Books yeah

@straceX Luhn algorithm

@FractalFactor hmm

@jtregunna hmm

@straceX Google the LUHN algorithm, that's how.

@ismyhc yes

Open any app: > Screenshot of a tweet > Screenshot of that screenshot on Insta > TikTok reacting to the screenshot > YouTube Short explaining why the screenshot problematic > Google search just sends you back to one of the above Infinite recursion. zero new ideas.

@franklinrolls yes

@straceX luhn-mod algorithm before AVS we knew this and could generate valid cards at will

@WowCoolTh4nks lol😂

@straceX In the 90s there were credit card generators you could use to bypass adult site verification. Good times.

@ComRicheyweb 👍

@straceX first digit indicates the issuer of the card. when that is known, there are a specific (known) number of digits for cards issued by that issuer. once you have the first digit - the rest is simple regex formulashq.com/the-ultimate-g…
