Correct.
The frequency was used to mark a free line on the AT&T system, which used in-band signalling. Playing this tone into the phone made the switch (but not the billing system) think that the line was free, and subsequent dialling would start a new call. This allowed "phone hackers" to make long distance calls for the price of a local call.

If only I had a good blue box to do this for me?
Oh, wait, I can grab one from Woz & Jobs.

The real phone hackers could whistle the correct tone. Harumph!

I was sure that, that kind of magazines are in electronics only... Or maybe an un-hackable copy is always a good idea?

A PDF file stored on a CD or DVD is pretty safe. OTOH, swatting flies with it is difficult...

Don't swat the flies. Dip your device in honey[^] and they will be attracted to it.

If it's not broken, fix it until it is.
Everything makes sense in someone's mind.

Was it in a computer class in high school or college? Did you implement an algorithm?
Sieve of Eratosthenes - Wikipedia
I actually first learned about it from my father when I was 10 or so, and worked it out on paper, haha, for the first 100 or so.

School I think, certainly well before I met my first computer, or even programmable calculator!
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Ditto. IIRC, this was not long after we learnt division.

I learned about the Sieve of Eratosthenes shortly after I was asked to drain the Pasta of Eratosthenes.

I never saw it in high school or college. Of course, that was back before Eratosthenes was even born. We did computing on punch cards made from antelope skin where we punched the holes using an awl made from the jawbone of a yak.

Found it on my own reading as I learned about the necessity of prime number use in public/private key cryptography.

In my case it was a book - Algorithms in C++ (Bryan Flamig) ... around 1995 ...

I just had to google it.
That means something, no ?
