China has reached a supercomputing milestone.

The country now has more machines on a list of the world's 500 fastest supercomputers than the U.S.

China has 202 systems on the Top500's supercomputer list, with the U.S. comparatively having only 143.

The U.S. ranking is its lowest since the Top500 rankings began 25 years ago, though the country still manages to come in at second place.

Japan comes in third with 35 supercomputers, and Germany fourth with 20.

According to Top500, China's managed to turn things around pretty fast. Just six months ago, the US led with 169 systems, with China slightly trailing with 160.

How fast is a supercomputer?
Supercomputers have a much higher processing capacity compared to a general-use computer, and a much higher speed of calculation.

They're used for various things such as weather forecasting, nuclear weapons simulation and even to track space activity.

The processing speeds of a supercomputer are measured in floating points operations per second, or "flops".

A "petaflop" is one thousand trillion "flops".

The world's fastest supercomputer, the Chinese Sunway TaihuLight, can reach up to 93 petaflops.


That's more than twice as fast as the world's second fastest supercomputer — which is also developed by the Chinese.

The U.S. in comparison, comes in at fifth place with the Titan, at a speed of 17.6 petaflops.

It looks like the U.S. has some serious catching up to do.


Science and Information / Uber is finally introducing upfront pricing
« on: November 14, 2017, 05:15:23 PM »
Previously, when you booked an Uber an hour or more in advance, you were just given an estimate of the fare. That could vary widely from the price you would be charged after the ride if there was an unexpected surge. The app noted on its "Fares" page that "Actual fares and surcharges may vary" from the estimate. But such "estimates" are no longer.

This new locked-in pricing feature is intended to ease the stress of travel. An Uber spokesperson told Mashable that customers have, in the past, most often been surprised by their final fares when bad weather or popular events led to unexpected demand.

You can budget around your ride without worrying about unexpected price increases. The change will give customers "one less thing to stress about ahead of an early flight," an Uber spokesperson told Mashable.

This feature isn't exactly new, though. Uber's chief rival Lyft rolled out a similar feature last year that shows users their locked-in rates for all rides. The total price that Lyft displays includes all fees, taxes, and tolls, and is calculated based on your "usual time and distance" if you don't initially select a destination.

Uber's feature is available in all U.S. cities where Uber operates. To use the feature, tap the car icon next to "Where to?" and select your date and time, add your pickup and dropoff locations, and select the type of Uber you're looking for. If your ride was scheduled more than an hour in advance, your upfront fare will be displayed.
