It’s an easy fix documented at https://www.nico-maas.de/?p=1562
Note that you no longer need to edit /etc/default/rng-tools - it will find the Pi's hardware random number generator automatically.

I'm hoping it is silver. I don't know what cadmium oxidation looks like, but it does look like silver tarnishing. I'm going to go with silver :D

Re: WLAN MAC address changes at every reboot?

The other possibility of course is that the LAN7515 holds the MAC address internally in which case, if no software is deliberately changing the MAC, something is broken. The Ethernet MAC is set by the driver and based on the Pi's serial number. The built-in WiFi MAC is set the same way, but the bot...

Re: AV Connector oxidized

It isn't "corrosion" it is oxidation of the cadmium plating, and is quite normal (and harmless). If you use it it should work, but attempting to "clean" is likely to do more harm than good. Corrosion *is* oxidation. And after some googling, I'm rather surprised to find that it is still legal to use...

Re: DVI-D to HDMI

1. Start with both the Pi and the monitor powered OFF and disconnected from the power. Also, disconnect the HDMI cable from the Pi and monitor.
2. Connect the Pi to the monitor with the HDMI cable. Keep power OFF on both.
3. Power on the monitor.
4. Power on the Pi.

Re: The MAC address of wlan0 on a Zero W on a default current stretch keeps changing

Re: Formatting SDXC SD card and installing OS image

If you are writing an OS image to the SD card, such as the Raspbian images from https://www.raspberrypi.org/downloads/raspbian/ , then you do not need to format the card. Use Etcher (or dd under Linux / OS X) to write the image to the card and it will just work without any messing about. You only ne...

Raspbian has Java 8 preinstalled. Since this is the default OS anyway, I would start with that. You may have to manually install it if you are using the 'lite' version (I've not checked):
