Long before the internet, some phone networks were hackable by playing a single tone at 2600Hz.

Whistled into a phone, it could grant you unrestricted access. Do you have the vocal chops to be an old-school phone phreak?

I built a web app to test your ability to produce the legendary frequency. You won't get free long distance calls but you will get some honor in the knowledge that you could have been a cool hacker. 😎

I am sad to say that I can only whistle up to 1100Hz... But my wife (a long time woodwind player) is able to consistently get it.

Few things infuriate me as much as someone posting screenshots or pictures of text pages and then just writing "screenshot of a text" or "a text page in a book" in the ALT text.

Visually impaired people have the same right to information as sighted people! It's not accessible to exclude us from the written content. And no, a brief summary like "a funny text about dogs" isn't accessible either. At least give some more details if you don't want to type out the whole text.

Stop excluding us!
