Rickroll the Terminal with curl

Ever wished you could find a new creative way to rickroll your particularly tech savvy friends? Just about nobody is fooled by the random YouTube links anymore, and URL shorteners alone aren’t always enough, but now you can bring the persistently annoying rickrolling to the Terminal of OS X and Linux by running a simple fairly innocuous looking command. What happens when you or the suspect runs it? You’ll get a full ASCII rendition of the infamous Rick Astley video but best of all it’s complete with audio, so be sure they have their speakers turned up or headphones on.

Being April Fools Day, the internet is largely useless, news is a mess, and much of what you’ll read today is inaccurate rubbish. But don’t worry, we’re not going to fall into that trap, and instead for April Fools we’ll offer up a few pranks that you can play on anyone that has an iPhone, iPad, or iPod touch. All you’ll need to do is get ahold of the individuals iOS device and each prank only takes a few seconds to implement, so plot accordingly and have some fun.
If you’ve ever wanted to get a foreign app that isn’t named in your native language, let alone native alphabet, onto your iPhone, iPad, or iPod touch, you’ve probably noticed it’s not the easiest thing in the world.

Some countries use fahrenheit, others use celsius, and if you’re an alien on an unusually extreme planet maybe you even use kelvin… whatever the case we’ve all run into the situation where someone from elsewhere is referring to a temperature in a scale you’re unfamiliar with. Obviously if someone in the USA says “wow it was 10 degrees!” that means it’s really cold weather, but if a native German said the same thing, that’s quite mild weather.
