  • It’s way more complicated to build a GW-scale power plant than a GW-scale data center, mostly because the power plant is subject to environmental studies, fuel supply, etc, so a DC looking for investors that can just say they’re going to build a big warehouse, fill it with computers, and get electricity, magically, from the local utility, gets to outsource the hardest problem, and stands a better chance of getting their funding (regardless of whether they actually build anything).

    I forget where I keep seeing that some huge fraction of proposed DCs will/are never built, suggesting that many of them are just investor scams. Showing their work on power supply would (presumably) make the scam harder to run.








  • I added homeassistant and some power monitors to my stack, and the IT rack comes in around 1.5 kWh/day - one of the biggest power budgets in the house, even with a low-power CPU, after adding in a few HDDs, a couple switches, and the cable modem. I’m also in a cheap power state, so it’s not a financial pressure, just surprising how quickly 10W here, 10W there…add up. At $0.50/kWh, I’d think solar would be a no-brainer.



  • Keep power in mind. For most home-use services, you don’t really need much computing power, and you might be able to do all you want with a single box. Even 30W, 24/7 is $25 (@10¢/kWh)-125(@50¢)/year of electricity. That said, it’s a small price to learn how to do clustering or swarms.

    I’d guess that your biggest load would be transcoding in Jellyfin, for which Intel Gen 6 added h265 to quicksync. The Gen 3/4 CPUs in M73 would be extra slow with most modern codecs.



  • My setup is a pile of kludges built on top of each other over the last two decades.

    I started with ULAs distributed through DHCP, connected to named, which allows hosts do declare their own name and let me access local services as though I had a real domain.

    My ISP eventually started supporting IPV6, but only assigned /128, so the ULAs got NAT-6ed out to the real world.

    I eventually learned how to request prefix delegation from the ISP and set up SLAAC.

    So now, my PIv6 clients have a) their link-local address, b) the ULA, c) a “privacy” SLAAC, and d) a unique SLAAC. All my internal services still refer to the ULAs.

    I don’t think I’d recommend this system for someone setting up from scratch. The easiest thing would be to go with SLAAC, if you can get prefix delegation, and set your DNS/pihole to send the unique-SLAAC address of any servers you run.





  • Right: SSA buys a treasury bill, and congress gets to treat that as income for the general budget. For a long time, SSA was the largest holder of US debt. Their surplus has been falling, while the Federal Reserve has bought up tons of Treasuries every time there’s an economic crisis and have now eclipsed SSA. Fed holds about $4.5T, while Japan holds barely $1.2T

    Whether you think of these inter-governmental loans as “investments,” is probably a matter of where you fall on pedantry. If I take a loan from my 401k for down payment on a house, I don’t think of that as “investing” my 401k in the house.
