    >Fortunately, those extra PCIe lanes tend to get repurposed as additional M.2 holes.

    Or unfortunately, for the unlucky people who didn't do their research, so now their extra M.2 drives are sucking up some of their GPU's PCIe bus.

    another insane thing is having 40 Gbps USB ports used as a networking cable between two PCs... Why there is still no project which can do this by simply installing trivial driver (in windows) and 4 line patch to enable this in linux? just charge 2 dollars per year and youll be milionaire (until LTT / MS catches up and steals it from you )

    It is even possible to have linux machine act as a display port sink to be used as a capture card, for streamers, youtubers,... with 0 dollar investment, 0 hardware...

    If I wanted to capture something with HDCP, what’s the most straightforward path to stripping it away?

    Nice to see another use for those lanes exposed with M.2. M.2 to OcuLink to a standard PCIE slot/carrier still seems more flexible tho.

    Looking for a way to freeze an HDMI feed so that the current image (a PPT slide) stays up on the projector/TV while edits are made. Any suggestions welcome.

    The website is wheezing a bit. Here's a link to the video https://www.youtube.com/watch?v=xNebV8KIlZQ

    Looking for a way to show an image over HDMI while my embedded system is booting, and then (seamlessly) switching over to the HDMI output of that system when booting finishes. Any ideas how to accomplish that? In hardware, of course.

    absolutely wild seeing all the ways people stretch these boards tbh - kinda makes me wanna mess with my own setup more

    >PCIe slots are becoming an endangered species on modern motherboards

    Except... not at all? Just about any ATX-sized motherboard is going to have a full-sized X4 slot and a small X1 slot _in addition_ to the X16 one.

    And with decent audio and 2.5GBps ethernet PHY on board even those slots often sit disused.

    I mean, want to test goofy hardware - go for it, no need to invent a justification.

    what exactly is this good for?
