    First up… backups…

    You’ve got all your data on a single 8TB external drive?

    This. RAID IS NOT A BACKUP !!! Sorry for shouting, but it’s that important. It’s a main storage tolerant of disk failure, you still need backups or you’re one bad ‘rm -rf’ away from losing data.

    First get that second 8Tb, or better yet a 16+Tb (see serverpartdeals.com or your local equivalent for good prices on manufacturer recertified drives) so you have room to grow. Now copy that 8Tb onto it and disconnect it from your computer. Congratulations, you have a cold backup and are pretty well protected from data loss, much better than a RAID.

    You can now think about a NAS with confidence, but preferably before that get another drive copy your data again and take it to a friend / relative / safety deposit box (even bury it in the back yard in something waterproof). Now you have a 3-2-1 backup strategy and you’re pretty damn well insulated against data loss.

    TLDR: Backup first, NAS later.




  • The tanks might go underground mitigating (perhaps) the pressure explosion risk as opposed to lithium fire risk, but the honking great tent is an issue. Should have a longer life than Li Ion and be repairable vs somewhat recyclable. At scaled production it could certainly be cheaper, but some of the newer immobile battery chemistries might beat it. Synthesized fuel also makes a lot of sense. We shall see. What certainly makes sense is microgrids and power self-sufficiency.





  • The ones with metal pigment are still waiting to fail, the ones that died used a cheap organic dye, coz profit. This is Silica (i.e. quartz, a long lived rock) with variances in polarization and intensity,( hence 5D when combined with a 3D Crystal))

    OK generic marketing crap and will you have their special reader in a century, but it’s a solid way to project knowledge into the far future (gotta wonder if we need to re-examine some quartz crystals with this in mind ;}











  • Didn’t take as long as I expected, but I expected it (which is why I didn’t bother to read, even if it’s not all the way there, it’s coming).

    Seriously, advertising (or propaganda to use the older name favoured by Goebbels) really needs to be seen as a much more serious enemy than most do. Propaganda for capitalists is super effective at sucking up peoples mental bandwidth, they’ve been selecting for it going on a century now and they’re depressingly good at it, if you don’t actively counter it, straight to the subconscious, along with all the background crap in it. /rant, but seriously…
