I’m beautiful and tough like a diamond…or beef jerky in a ball gown.

  • Not sure if ADHD specific or a symptom of being “on the spectrum” or a bit of both (have never been diagnosed either way but show all the signs), but I have a very low capacity “social battery” and am very sensitive to noise. The end result is I crave (relative) solitude and quiet or else I’m useless at getting anything done.


  • An unmanaged switch is just a single plane where all ports are equal. All ports share OSI layers 1 and 2. Anything you plug into port 24 can always reach anything you have plugged into port 3.

    Managed switches (also sometimes known as “smart” switches) provide additional features on top of that. The most useful is VLANs (virtual LANs) which let you segregate traffic. Two ports on different VLANs share the same physical layer (layer 1) but are separated at the data link layer (layer 2). This lets you create up to 4096 different networks on the same switch; each network is isolated from the other. If port 24 and port 3 are on different VLANs, then they will not be able to communicate unless they can reach a common router at layer 3.

    Additionally, managed switches let you do things like disable/enable ports (for security, power savings, etc), enable port mirroring, and combine multiple ports into an aggregation group (e.g. bond four 1 Gb links into one 4 Gb link).

    The available features on a managed/smart switch vary by manufacturer and, often, by the license level (sadly common in enterprise gear). VLANs, port control, mirroring, and LAGs are usually common “baseline” features, though.













  • I have an old rotary phone / bluetooth “headset”! Though it’s only technically portable.

    It’s a 50’s wall-mount model that the phone company would have hardwired (no RJ-11). I’ve got it hooked to a Bluetooth -> POTS adapter that will decode the pulse coding. It rings when my cell rings, you can answer/place calls from it, and you can dial 0 to engage the voice assistant. Technically speaking, I can absolutely text people from a rotary phone.

    Is it practical? No. Do I use it? Rarely. It’s mostly decorative, but if I’m going to have retro tech as decorations, I like to make it work. Next “wish list” is an old payphone.


  • not amazing as a Bluetooth device. Microphone didn’t pick up super-well

    That’s disappointing. Seemed to work well in that video, though it was quiet; I did wonder how it would fare in the real world, though.

    A Bluetooth version of the TMP communicators might have better success albeit at the cost of having to hold your arm up for the whole conversation.

    I’ve used smart watches for phone calls like that, and it was pretty annoying after not very long at all.

    I could probably easily make a Bluetooth TOS communicator, but that would be two roughly phone-sized things to carry around, so not really practical.

    OTOH:
