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, a skill made famous by legends like Cap'n Crunch. 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.

I send thanks to the buyer from the Netherlands who purchased an iPhone case of

May the image on the phone case transport you out of the world of tech and into the world of nature.

Google is wholeheartedly embracing AI technology and its new tool could rejuvenate the internet or bring about the apocalypse for websites.

This is another of those scenarios @pluralistic is fond of reminding us of, where those responsible were warned, loudly, before the damage & forged ahead anyway.

It's bad enough that we, modern humanity, collectively, can't stop pissing where we sleep, but rewarding the biggest bed pissers with billionaire status might be just a little over the top in terms of bad idea'ness...

What I’d like to have is getting asserts and types checked at compile time and at run time.

@khinsen It is interesting you say that, because I had just started reading this paper which seems to discuss a technique that does what you are asking:

“A Practical Soft Type System for Scheme.” Andrew K. Wright, Robert Cartwright

I haven’t read the whole paper yet, but their approach apparently rewrites a Scheme program to a new output file, and it does a type inference and static type checking pass in the process. They apparently declared types for every API in the R4RS Scheme standard library. The rewritten program also has assertions for runtime type checking inserted wherever the type checker deemed that it was not able to check the type statically.
