Would plugging or unplugging the Coax cable from router before turning the router off cause any damage to the router or the cable?

Would plugging or unplugging the Coax cable from router before turning the router off cause any damage to the router or the cable or anything? Because I accidently unplugged the coax cable from the router before turning it off.

Send audio from Mac to Linux via USB cable

Using a Mac mini Mid 2011 running Catalina and a Dell Inspiron Mini 1012 running Raspbian (Debian 4.9), I currently have a 3.5mm cable connecting Mac headphone port to dell mic port. Dell equalizes the sound using Qpaeq/Pulseaudio and then out to speakers. Having some quality issues so I want to run digital instead of analog. I want to use a Usb cable and run all the audio digitally from Mac to Dell instead of 3.5. What terminal commands do I need to do to the dell to set up a USB audio device and have it be recognized by the Mac as a possible output device?

Inspired from this article https://www.cnet.com/how-to/make-the-most-out-of-your-computers-usb-audio-port/

How to get videos off Android phone with USB cable?

I’m on the newest KDE Ubuntu and just trying to move some large videos from the phone to my computer. The KDE connect works great but is too slow for videos.

When I connect to the phone with USB, the “Storage” folder is locked and I get the error message when I try to open the folder: Could not enter folder /media/l/disk/storage and can’t open Dolphin with Sudo.

Can’t connect monitor with vga cable ubuntu 18.04.3

My Laptop (Dell Latitude e5270) cant be connected with monitor via vga cable(hdmi works good). If I plug it in, nothing happens, I can only use the built-in screen (or any HDMI monitor I plug it into).

The said VGA monitor itself works, as I use it with other devices and it connects fine through the cable. My laptop connected without any problems to a VGA monitor on ubuntu 17 version i think.

Intel® HD Graphics 520

xrandr while the VGA is plugged in:

Ethernet Adapter Detected but the ethernet cable isn’t

I recently bought a usb ethernet adapter as my laptop has no ethernet ports. The laptop detects the adapter, the driver is installed, but the ethenet cable isn’t detected. The cable works fine for other laptops. the results of ethtool enx00e001103008 shows:

Settings for enx00e001103008:     Supported ports: [ TP MII ]     Supported link modes:   10baseT/Half 10baseT/Full                              100baseT/Half 100baseT/Full      Supported pause frame use: No     Supports auto-negotiation: Yes     Supported FEC modes: Not reported     Advertised link modes:  Not reported     Advertised pause frame use: No     Advertised auto-negotiation: No     Advertised FEC modes: Not reported     Speed: 100Mb/s     Duplex: Half     Port: MII     PHYAD: 0     Transceiver: internal     Auto-negotiation: off     Current message level: 0x00000007 (7)                    drv probe link     Link detected: no
