That was the Nexus 6P. Nexus 6 was made by Motorola and overall an amazing phone

Keepalived

I run multiple pinholes using keepalived. Then I only use one DNS in my DHCP server. Second pihole will seemlessly take over if the first one goes down whilst using the original DNS address.

Work quite well. I had to learn the hard way that only using a single pihole was just asking for my partner to be mad when it didn't work / when I was doing server maintenance. Now I have multiple and they can all seemlessly take over if any my server nodes are down

I'll die before I give up my automatic wipers! Thankfully my 2004 and 2013 VWs have it and don't lock me out of features like new cars.

Linux runs on anything.

That is not correct. The DRAM is not part of the same die that the SoC is on. It is separate packages directly beside the SoC. The storage is also separate packages.

If it was all one die it would be huge and have poor yields.

I am sure I am in the minority, but avoid AAC multi channel encodes as much as possible. It really makes no sense for anyone. Most home theater equipment does not support it. AC3 or eAC3 are supported by nearly every device natively. AAC does not work over SPDIF or HDMI ARC without reencoding. All that for a slightly lower bitrate? No thanks. Plus most are likely encoded from a AC3 or eAC3 so they will sound worse than the native version.

A heat pump isn't any more efficient than a AC only unit of the same SEER rating. They are literally the same system with the heat pump having a couple extra valves and parts to reverse the flow of the refrigerator.

"Modern Device" aka Apple TV, AndroidTV, iOS or MacOS. No app for Android phones.

The core technologies that UTDC (then Bombardier, now Alstom) took from this is still being used all over the world. The new Vancouver SkyTrain is still using Linear Induction Motors.

A lot of light rail uses resilient wheels and heavy rail does not.

Wheel profiles (the shape of the part that actually touches the rail) are also very different between different categories.

Wheels are 100% different on Heavy Rail, Metros and Light Rails.

In addition to that all 3 have different requirements for curves, runout and grades.
