  • The title is a bit weird. On my first reading it makes it sound like two different people can have indistinguishable fingerprints. But after reading/skimming the article+paper, it seems like what they’ve actually done is been able to correlate fingerprints from different fingers on the same person.

    So the title makes it sound like they’ve weakened the basis of fingerprinting as forensic evidence, when in fact they’ve developed a way to link the different fingerprints from the same criminal so that additional cases could be solved.

    e.g. if a criminal only left a thumb print at one crime scene and an index finger print at another, this posed a problem for investigators because they couldn’t link them to the same person, but this “AI” approach can link those two different prints to the same person.






  • From the article:

    The bad news is that the 6 GHz wireless spectrum uses shorter wavelengths. Short wavelengths are great for fast data transfers at close range, So, they’re great for connecting to your Wi-Fi 7-enabled HDTV a few feet away from your router

    With a range that short, you’re not going to be doing much roaming around. It obviously has some use cases, but unless you need to be streaming data it doesn’t make a lot of sense.

    The example we are discussing in this thread is transferring data off of a high res/high performance camera. For many situations this can be done after filming is completed, in which case a cord still makes a lot more sense. Hence my joke.

    For live broadcasting it could be useful, but the range still seems quite limiting.
