  • With TrueNAS yes, a sata card connected to a bare drive is the preferred way. I have done it differently with enterprise hardware and virtualization but it’s not really supposed to be done that way. And ZFS is not technically “RAID” in the classic sense, but it does implement its own RAID‑like redundancy (RAIDZ and mirrors) as part of an integrated filesystem and volume manager. There are also things you can do with faster NVME drives like SLOG, L2ARC, and SPECIAL vdevs to store pool metadata. But some of these can fail and wipe out all your data if you aren’t careful. So read a lot.

    Second hand drives are fine in my opinion as long as SMART is not reporting any immediate errors. Just assume you will have failures and have spares built into the zfs volume.

    I’m not an expert by any stretch but I have been doing this for 10 plus years so I have some experience.










  • Human bodies are terrible electrical power sources…even if you harvested all their metabolic heat or chemical energy, you would get far less usable electricity than a comparable mass of conventional fuel or batteries. Much more efficient ways to turn biochemicals or biomass into energy exist.

    And to use us as batteries we need food. I would venture to say at least 99% or more of human food production requires sunlight. So just use sunlight for energy. No sunlight because of horrible nuclear winter or something else blocking the sun? Create satellites to collect it and beam it down with microwave lasers.

    Anytime you convert a form of energy to another you lose energy. So sunlight->food->human->electricity is not only inefficient but dumb. An AI would never do this. The Wachowskis were writers, not scientists or engineers, and it shows. What would we be good at? The human brain is exceptionally good at massively parallel, low‑power pattern processing: recognizing, predicting, and adapting in complex, noisy environments. This sounds like the exact sorta thing you’d need if you were creating a virtual world. The trick would be getting the interface right. Assuming they had enough time that could be accomplished. So the whole reason the rumor of us being used as processors instead of batteries, is because it makes WAY more sense.







  • I’m not sure that’s possible with multiplayer games, at least the central server part. They could release the central server code as an open source project… that would be very useful. But MMOs need that central communication to even work. I mean I guess you could engineer some sort of peer to peer but I’ve dealt with weird firewall rules in various DCs I’ve had servers located in or god forbid the lack of incoming connectivity in peoples homes. Outbound traffic is usually fairly unrestricted so a publicly available server is the way to go architecturally.
