Tips With Siri

Sure, you could use the calculator, or any one of a dozen-odd apps that allow you to tap the screen and calculate the tip in a restaurant, but why even bother? iOS and Siri can meet your needs just by talking to your iPhone–or iPad, but won’t that get meatloaf gravy all over it?

Regardless, here’s how to ask Siri the right way to calculate the tip for the super-helpful server or bartender in your life.

How Super Algorithms Will Make Future iPhones & iPads Charge Twice As Fast

Plug in your iPhone or iPad and charge it up, and you’ll notice that while the first 80% or so will go by pretty fast, they actually kind of suck at charging up that last 20%, taking a lot more time to do so than it feels like they should.

There’s a reason for this. Charging batteries up to “full” is a complicated process. There’s no real way to tell if a battery is completely “full” so all you can do is measure the voltage, which (and this is a vast simplification) tells you how much resistance is being met when you try to put more electricity into the battery.

That’s why it takes so long for an iPhone to charge that last 20%. It charges full blast until it measures a certain voltage, then goes into what’s called “trickle mode” to slowly allow small sips of electricity into the battery until it thinks, based upon some software calculations, that the battery is more or less full. But a new algotihm could make the time it takes to charge your iPhone or iPad go by a lot faster.

This iOS App Blows Your Mind In Four Dimensions [Review]

If, like many people, you find Mondays just too much to cope with, you might want to avoid today’s app. It’s not the sort of thing that’s going to make your Monday feel any better, and in some cases it will just fry your brain until next Monday. Which would be a shame, because you’d miss out on a whole weekend.

Be forewarned, then: The Fourth Dimension is an app which will mess with your head. Deliberately. Even though the aim is education and expansion of knowledge, it will still mess with your head. You will emerge from the experience only fractionally the wiser, and quite a lot more confused than you were at the beginning. Don’t worry, this is perfectly normal.

Ever wonder how those funky aperture numbers ended up on your lens barrel? Or who chose those odd ƒ-numbers that run in the seemingly arbitrary 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32 sequence? And why does the biggest number refer to the smallest lens-hole?
