• Who’s to Blame for Plastic Microfiber Pollution?

    Instead, they pointed the finger of blame at the washing machines themselves, specifically how water moves through clothes. You might assume that synthetic clothes will shed more microfibers if they’re packed tightly in a big wash, rubbing against one another. But these researchers found that high-efficiency machines, which use less water, also created less fiber loss. “The big surprise is really that it’s not all about agitation,” says Procter & Gamble researcher Neil Lant, lead author on the paper. “The big reason for fibers being lost in washing is actually the force of water flowing through the textiles and the yarns. And that’s what actually causes unplucking of fibers.”

    The age of the clothes matters, as well. Lant and his colleagues found that new garments are the highest shedders—maybe thanks to loose fibers left after the manufacturing process. “When you get to about washing them six to eight times, you

  • 4 features that Apple ‘borrowed’ from Android but made it so much better in iOS 14

    Apple has been playing catch up with Android for many years now. It has always picked features from Google’s mobile operating system, implemented it into iOS, and worded it in a way that makes it seem like the feature is something no one has done before.

    Every World Wide Developer Conference (WWDC) I would scoff at the company presentation and how they ‘revolutionize new’ features that already exist.

    But I won’t deny that every time Apple ‘borrows’ a new feature from Android, they always seem to make it better one way or another. Here are some examples:

    Apple’s App Library makes so much more sense compared to Android’s App Drawer

    For years and ever since I can remember, Android had a place where with a swipe or tap, you can get access to all the apps that are installed on your phone. If you

  • ARM-based Japanese supercomputer is now the fastest in the world

    A Japanese supercomputer has taken the top spot in the biannual Top500 supercomputer speed ranking. Fugaku, a computer in Kobe co-developed by Riken and Fujitsu, makes use of Fujitsu’s 48-core A64FX system-on-chip. It’s the first time a computer based on ARM processors has topped the list.

    Fugaku turned in a Top500 HPL result of 415.5 petaflops, 2.8 times as fast as IBM’s Summit, the nearest competitor. Fugaku also attained top spots in other rankings that test computers on different workloads, including Graph 500, HPL-AI, and HPCG. No previous supercomputer has ever led all four rankings at once.

    While fastest supercomputer rankings normally bounce between American- and Chinese-made systems, this is Japan’s first system to rank first on the Top500 in nine years since Fugaku’s predecessor, Riken’s K computer. Overall there are 226 Chinese supercomputers on the list, 114 from America, and 30 from Japan. US-based systems contribute the most
