This would probably be a lot more interesting if you gave some background information, or even at least mentioned phreaking.

The youth will never know the joy of using your yakback to record keypad tones and playing them back to cause the phone to dial out without touching any buttons 🥲

Because @sanitation@lemmy.today was unable to properly add sources, I helped them out by looking for something on Wikipedia:

The tone was discovered in approximately 1957,[9] by Joe Engressia, a blind seven-year-old boy. Engressia had perfect pitch, and discovered that whistling the fourth E above middle C (a frequency of 2637.02 Hz) would stop a dialed phone recording. Unaware of what he had done, Engressia called the phone company and asked why the recordings had stopped.[10]

Joybubbles was a beautiful and unique human being.

If “the scene” (hacking, phreaking, etc) has foundational figures, Josef Carl Engressia Jr. is definitely one of them. A biopic came out just year but I haven’t seen it.

If you’ve seen the fantastic 1992 movie Sneakers, Whistler is mostly based on Joybubbles.

This headline has more plot points than a novel.
