    If you could force different speeds and different voltages, you can make some guesses as to what the cable might support.

    USB packets use CRC checks, so a bad checksum may indicate a speed or physical problem.

    I just looked over the source code for libusb (like I knew what I was looking for, or something) and it seems that some of the driver(?) components hook really deep into the kernel. There might be a way to test specific parts of any type of handshake (for dataflow or voltage negotiation) to isolate specific wires that are bad by the process of elimination.

    I think my point is that a top-down approach is likely possible, but it’s probabilistic.



  • I am curious as to why they would offload any AI tasks to another chip? I just did a super quick search for upscaling models on GitHub (https://github.com/marcan/cl-waifu2x/tree/master/models) and they are tiny as far as AI models go.

    Its the rendering bit that takes all the complex maths, and if that is reduced, that would leave plenty of room for running a baby AI. Granted, the method I linked to was only doing 29k pixels per second, but they said they weren’t GPU optimized. (FSR4 is going to be fully GPU optimized, I am sure of it.)

    If the rendered image is only 85% of a 4k image, that’s ~1.2 million pixels that need to be computed and it still seems plausible to keep everything on the GPU.

    With all of that blurted out, is FSR4 AI going to be offloaded to something else? It seems like there would be a significant technical challenges in creating another data bus that would also have to sync with memory and the GPU for offloading AI compute at speeds that didn’t risk create additional lag. (I am just hypothesizing, btw.)





  • “Your TV has become a digital billboard.”

    It’s been a digital billboard for at least 40 years of my life. Radio was no different, so be sure to drink your Ovaltine.

    Have you never seen a commercial before? Cheap subsidized hardware? Bloatware loaded on phones? Bloatware on TVs? Games that require 5 mins of ad time? Google’s crippling of Chrome to break ad blockers? Unskippable ads on YouTube? Sponsored ad spots in YouTube videos? All the 3rd party logos on Smart TV boxes? Product placements in movies? Ad placements before the movie starts? The list goes on.

    The entire entertainment industry is based around advertising. Every delivery platform is designed to show you ads first and entertainment second.

    People have problems figuring that out?





  • Yeah. Modern phones are awesome if you need to use every feature to its fullest. I love that I have the opinions to access my accelerometer or GPS independently. Since I do a bit of CAD work, having a high quality camera is awesome for photogrammetry. But see, there is a caveat: It’s the right tool for me and worth my $1K to have an up-to-date device that has a reasonable bit of compute.

    Otherwise, nah. I just got a resin 3D printer that only has a USB connector. No cloud, no wifi, no bullshit. It does its one job well and that is all I care about.

    It sucks that most people are basically trained from birth that “more is better” or “brand new is better”. It took me years to de-program myself from that shit.



  • Folding phones are still a status symbol of some kind and the actual utility of a large phone screen is lost on most owners. Once most of the R&D cost is paid off and the tech starts to plateau, it might get cheaper?

    I see foldable screens as a work device. Sure, a portable movie theater would be a good perk, but it would absolutely rock as a commercial all-in-one console for a 3D printer farm or something. If there is enough commercial value in a device like that, $2k could be a bargain.
