  • if you invert the flow of electrons, a receiver becomes a transmitter

    Ehh not really. That’s kind of like saying if you invert the flow of photons, your eyes work as flashlights.

    “It could be possible with some changes” the changes would amount to removing the receiver and replacing it with a transmitter. In this specific case I’m not sure if a transmitter already exists at this antenna and it’s definitely possible one does, but that’s not a guarantee at all






  • It certainly is. ISO 27001 is a framework, not very prescriptive at all. Basically an auditor will ask “how do you ensure data isn’t leaving your facility in the form of discarded hardware?” If you say “here’s a link to our media destruction policy. It says all drives are wiped according to NIST 800-88 cryptographic erasure. If that is not possible or not applicable, the drive is destroyed. Here’s our log of decomissioned equipment” chances are very good they’ll say “OK great let’s move on to the next one” with only minor followup questions.







    1. RAID for uptime, backups for data you care about. RAID(1+) will keep your data online when a disk fails, but backups are the real way to keep data around if shit hits the fan. For a personal media collection, you might be better served with a non resilient RAID0 (total failure if one drive fails) with a backup around to recover from when that happens. If you do e.g. a raid5 you lose 1 disk of capacity in exchange for 1 disk of resiliency, raid6 same but 2 disks. That gives you some safety but there are a lot of instances where those raids don’t save you from losing all your data. If you buy 4x 18TB drives, you could have 36TB from the 1st two drives and then backup to the other two drives.

    2. There’s no specific type of drive to worry about unless you’re doing RAIDs especially with ZFS. Search shingle RAID rebuild for the biggest thing to worry about there.

    3. Almost always, yes. Slow drives throttle the rest.

    4. I’ve never used them but people say good things about synology most of the time. Everything comes with a cost and it’s hard to make any sensible recommendations without knowing your constraints; primarily your budget.
