  • It would require as much, or more, power to drown out a TV broadcast signal at the source. I believe many of the old towers were 200kW-1000kW so it would have taken one hell of a pirate signal if interfering close to the main source. However, RF follows the same principle as light using the inverse square law so the further you get from the primary transmitter, the signal quickly becomes exponentially weaker for any receiver.

    If you had a TV transmitter on a small hill that is a fair distance away from the target audience, like many were, splitting the distance with a directional antenna wouldn’t require nearly as much power from the pirate signal to overtake the original transmission.

    If I wanted, I could interfere with ham radio signals with as little as a watt of power (in my immediate local area) even though people might be communicating through a ham radio repeater that transmits at a couple of thousand watts that is many miles away. (It’s actually a permitted emergency technique to “break into” active conversations. Actually, other ham radio operators are familiar with what interference sounds like, even for signals that can’t fully overtake a transmission. It’s customary to stop the conversation if detected and wait for the “break”.)







  • I second the litterbox with a cover suggestion. It should help a bit, or at a minimum, keep the scratching confined to the litterbox itself.

    Still, scratching like this isn’t uncommon for cats. What I have noticed with my cats over the years is that they start young learning to cover the smell but they forget “why” they do it and “scratch whatever” out of habit as they get older. (I am talking many years or transition, btw.)

    Once cats get really old, having them used to a litterbox cover helps if they start to miss the litter completely. (We had an “old man” once that just forgot how to aim and his butt always ended up over the edge of the box.) Still, not something you hopefully need to worry about any time soon.

    TBH, each cat behavior is unique. Watch and adapt as you can.

    Its just complex

    When a security mechanism becomes more complex to manage than what it is supposed to protect, it becomes a vulnerability itself.

    If you had a minimal system that you built from the ground up yourself and wanted to only have that system function in very specific ways, SELinux would be perfect. I would go so far as to say it would be nearing perfection in some ways.

    Sorry, but in the real world, ain’t nobody got time for that shit. If you use auto configuration tools or pre-canned configs for SELinux on a system you are unfamiliar with, it’s more likely to cause application issues, create security gaps and will likely be shut off by a Jr. admin who really has no fucking clue what he is doing anyway.

    It’s just easier to keep your system patched and ensure basic network security practices anyway.

    It’s not impossible to manage these days. In the early days it was, but most everything is automagic now. If I am not mistaken, SELinux can be enabled to ‘log only’ which would give you data better handled by a HIPS anyway. (Don’t quote me on that.)
