  • the link light is powered by the switch

    No it’s not. If you don’t believe me, unplug your PC’s power cord and watch the light go out.

    If the power cord is plugged in but the computer is shutdown, and the light is still on, then that means the network adapter supports WoL or OOB management and must stay on for that reason, but the network switch connected to the adapter is not physically powering any lights.

















  • So blown out of proportion. Nobody is saying to stop using them. The report is more of a state of the union on software in secure systems and the talking points hinge on the most common type of vulnerability seen in large scale attacks: memory safety.

    The report (which apparently barely anyone is reading) mentions C/C++ aren’t memory safe (truth) and with specific respect to space flight, alternatives such as Rust haven’t been proven yet. Both languages meet other important criteria (again specific to space flight) but it then immediately states afterwards that until other languages can be qualified, other means of ensuring memory safety are recommended such as hardware. The report makes other mentions. It’s a good read but is not a directive like media is making it.
