Noob question about PiHole
  • 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

  • 8GB RAM on M3 MacBook Pro 'Analogous to 16GB' on PCs, Claims Apple
  • 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.

  • Heat pumps can't take the cold? Nordics debunk the myth
  • I am all for heat pumps, in fact 6 years ago when we had AC installed (in Ontario Canada) at a house we just took ownership of, I had asked for a heat pump and basically all installers said not available. Now they are all the rage.

    Anyways. Electric heat is 99.9% efficient. I know that heat pumps aren't making heat like electric heat does, but I can't see how at those temperatures you get more than 2 watts of heat for every 1 watt of heat you put in. Especially when you consider the defrost mode on most units just puts the heat pump into cooling mode for a moment, just long enough to produce heat on the outdoor coil, which in turn will provide cooling inside.

    I am not saying that they don't work. I just don't buy this twice as efficient bullshit.

  • Library Rebuild Suggestions
  • 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.

  • Why are maglev trains still rare?
  • 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.

  • Can anyone help me with Plex and 4K content?
  • AAC is such a stupid codec to use for anything other than 2.0 channel.

    5.1 / 7.1 AAC doesn't work over ARC. Over eARC it need to be decoded to LPCM and then sent out. It doesn't work with SPDIF.

    Both eARC and SPDIF will most likely get downmixed to 2ch.

    448 or 640kbps AC3 is perfectly fine and has great compatibility, SPDIF, ARC, eARC. Pretty much all blurays and DVDs will also have a AC3 track.
