  • Thunderbolt 5 vs Thunderbolt 4 -- everything you need to know

    Asynchronous has nothing to do with split speed. The correct is asymmetric transfer, when the speed is 120/40 and symmetric when the speed is 80/80. 

    Asynchronous/synchronous has to do with timing. For synchronous transfers both the sender and the receiver have a common clock, which determines the transfer rate. With async transfers, start and stop bits are used or some other means to mark the start of a transfer.

  • Philips Hue to gain support for Siri Shortcuts this fall

    "In related Philips Hue news, a new feature will be launching soon that allows lights to retain their color and brightness whenever there is a power outage or manually toggled off" Yay!

  • Inside iPhone 8: Apple's A11 Bionic introduces 5 new custom silicon engines

    It will be interesting to see whether Apple decides to support Google’s codecs. It’s up to Apple to do that. Since it’s free to support, I can’t see why they wouldn’t, unless it just corporate rivalry on their part.

    remember that Apple never supported FLAC for music either, but now they do. So that’s a change.
    Maybe on a Mac or AppleTV, but decoding 4K video is rather computational intensive, and therefore Apple has implemented h.265 decoding in hardware on the iPhone. While it may be free of licensing costs to use VP9, implementing a hardware decoder for it is not.
    Therefore Apple can implement it in software, but that means the video might lag, because its too computational intensive to decode in software, or even if it's fast enough it will have a negative impact on the power consumption and battery life.

    I think it's better if every streaming service could agree on one standard like HEVC.

    The video says the graphics have been upgraded with an M11 processor which is faster than the M10. The M co-processor isn’t anything to do with the graphics, right?

    You're absolutely right. The M11 is the Motion coprocessor, which handles data from all the motion sensors (accelerometer, pedometer, gyro etc).

  • Apple developing dedicated AI chip called Apple Neural Engine

    I was under the impression that the barrier to good AI was software not lack of CPU speed. If we had blazing fast chips today would Siri suddenly be amazing? I think not.  
    Of course AI needs good software, but that software has to do billions of complicated computations, and therefore raw processing power is needed too. Last years WWDC, in a talk about the Photos app it was mentioned that when you take a picture with the iPhone camera, around 11 billion calculations are made, to tag the picture with metadata about what's in the picture (face recognition and objects like cars, beaches, cats, dogs etc).
