Mathematicians Discover the Perfect Way to Multiply

Four thousand years ago, the Babylonians invented multiplication. Last month, mathematicians perfected it.

On March 18, two researchers described the fastest method ever discovered for multiplying two very large numbers. The paper marks the culmination of a long-running search to find the most efficient procedure for performing one of the most basic operations in math.

“Everybody thinks basically that the method you learn in school is the best one, but in fact it’s an active area of research,” said Joris van der Hoeven, a mathematician at the French National Center for Scientific Research and one of the co-authors.

The complexity of many computational problems, from calculating new digits of pi to finding large prime numbers, boils down to the speed of multiplication. Van der Hoeven describes their result as setting a kind of mathematical speed limit for how fast many other kinds of problems can be solved.

Diving into Google Cloud Next and the future of the cloud ecosystem

Extra Crunch offers members the opportunity to tune into conference calls led and moderated by the TechCrunch writers you read every day. This week, TechCrunch’s Frederic Lardinois and Ron Miller offered up their analysis on the major announcements that came out of Google’s Cloud Next conference this past week, as well as their opinions on the outlook for the company going forward.

Google Cloud announced a series of products, packages and services that it believes will improve the company’s competitive position and differentiate itself from AWS and other peers. Frederic and Ron discuss all of Google’s most promising announcements, including its product for managing hybrid clouds, its new end-to-end AI platform, as well as the company’s heightened effort to improve customer service, communication, and ease-of-use.

Star Wars Jedi: Fallen Order – release date, trailers and news

Hold on to your lightsabers: there’s a new Star Wars game in development, and it’s called Jedi: Fallen Order.

The reveal came in a surprisingly low-key fashion during EA’s conference at E3 2018, during an off-the-cuff interview with Vince Zambella, co-founder of Respawn Entertainment (of Titanfall fame).

And we’ve now been treated to a teaser trailer, which you can see below. This isn’t actual gameplay, but it gives you a flavor of the story. Players take on the role of Jedi-in-hiding Cal Kestis, EA and Respawn Entertainment revealed at the Star Wars Celebration event in Chicago.

While fans of the galactic franchise have seen official tie-ins in the form of Star Wars Battlefront I and II, the new entry takes on a different tack, focusing on a single-player experience more in line with 2008’s The Force Unleashed – and we have all the concrete news and wild speculation you could want below.

Cut to the chase

  • What is it? A new single-player Star Wars game from the creators of Titanfall
  • What can I play it on? It’s all but certain we’ll see it on PS4, Xbox One, and PC
  • When can I play it? Autumn/Fall 2019

Withings Move Smartwatch Review: A Few Steps From Greatness

In 2014, the French brand Withings debuted the Activité watches. They were remarkable—classic, understated analog watches that also functioned as a simple fitness trackers. (Disclosure: I bought an Activité Steel.)

Withings’ line of health care products were so beautiful and well-designed that Nokia bought the company in 2016. For the next two years, it befuddled everyone by appending the Nokia brand name to every product. My Activité Steel became a Nokia Steel. Then Nokia got bored. In 2018, Withings’ original founder Éric Careel bought back Nokia’s health division, and shortly thereafter caused a splash at this year’s CES with two new releases, the Move and Move ECG.

Like the Activité watches, the $70 Withings Move is a fitness tracker disguised as a disarmingly attractive analog watch. It’s remarkably affordable and can track your steps, record activities [...]  read more
