Nope. I don’t talk about myself like that.

    Most of the hardware itself was free(business decommissioned) or auction wins (4.5TB of ram out of a $600 auction, selling some servers paid the whole auction off). So quite cheap in that respect. And it’s not strictly private use. Lots of functions in there to keep my business going/make it easier to track taxes/auto billing clients/email/etc. Though only typically operationally, not as an income generator itself (eg, not hosting other companies stuff so much).

    And yeah, if energy was 10x more expensive (I think it was you or someone else that said $0.60 per kWh?) I’d probably rethink my situation/stance a bit.

    But 3kW service is awfully low. Standard around here is 200amp service to a house (at 120v, so 24kVA service), 100amp (12kVA) if you have gas utilities handling range/heating, as A/C is heavily required where I live. My PV setup is rated 15.9kW, though caps out at 11kW on the best days. I can’t imagine living off of 3kW. My desktop uses 1/10th of that. My idle usage in my house minus the servers is ~2kW. I can see why you’re squeezing Watts. Some googling shows Italy being a country that does this… You probably are in similar situation as them where A/C isn’t really common, heating and cooking isn’t electric based, etc… Most of the year I’m not allowed to even make a fire, so I’m forced to rely on electricity.

    But no SUV here… 1 hybrid sedan for this family of 4. Gas costs too much and we drive too little.

    And here I am with a 5 server cluster, 2x custom servers running opnsense for redundancy (8gbps internet connection needs real horsepower for IDS/firewall/routing), and a 36 bay storage truenas node… that’s getting upgraded to 72 bay version for more drives (34 additional drives ready for install RIGHT NOW)… I see your 50 and 38 W… and raise you

    This

    2200-ish watts? Oh… and cooling the servers to keep them to about 75 degrees intake temp.

    So really closer to 3400 watts.

    Taking your numbers of 6 watts saved per drive would only save me 180w currently and 432w after I install the additional 32 drives next week. I’d still be in the 3kW territory.

    I also have solar…

    I generate (orange) enough to export (purple) a little during the day… but that’s about it… Battery (light green) usage just kills peak hours.


    The electrical usage costs me about $100-110 a month in electricity after solar ($0.06 per kWh), probably closer to $150 if solar wasn’t eating up a bunch of it. Less than subscriptions to all the shit that I’m hosting for myself by a long long shot. Forget the family and other users.

    More information... Not even remotely necessary to read.

    Nextcloud - 5TB, google drive is $10/mo for 2TB
    MSTY - AI stuff, another $10/mo subscription if you want google gemini. $20 for ChatGPT. Minecraft - private, $5 a month minimum. Probably closer to $10 for reasonable specs to do anything with the kiddos.
    Email - 1TB across all users right now, ~$5 minimum for just me, though I’m oversize for many platforms as I have everything going back to 2006 or so. So probably close to $8-10 for just me.
    Private search aggregator - apparently a paid service now with the likes of kagi. $10
    Home assistant - $6.50 through nobucasa.
    $46-66 on this stuff alone…

    Frigate… 8 cameras with corals for inferencing. God know what that cost would be. I keep 30 days of 24 hours, 6 months of detected items and 1 year of snapshots. I’m at 50TB of usage there. This probably could/should be cut down significantly, at least halved. but even 25TB is a fuck-ton of money per month on any VPS/hosted system. Ring’s plan is about half what I’m doing at $20/mo. No idea what other services would end up being. Not even sure how ring and other make money at that cost when storage is expensive otherwise.

    Paperless-ngx, lubelog, grocy, gramps for organization/documentation would need a VPS service… or migrating to a non-hosted solution (so can’t really be shared easily, or shared through google docs sort of thing).

    Self-hosted things like lemmy, mastodon, matrix, peertube, etc… VPS costs would be something substantial as well. And business operation stuff like my invoices, jump hosts, secure vms, etc…

    And lastly, the cost of owning my own data… where no company can spy on me. Or monetize me in ads. Invidious, my own dns with custom rules for me vs the kids, etc…etc…etc… Priceless.

    Then multiply the parts of the list for other users on my system (wife, both kids, father, etc…)

    And of course the massive porn collection… Gotta have that on a moments notice.

    That aliexpress device doesn’t tell you what wattage or data speed the cable will max out doing. Just what wattage it’s currently doing (to which you’d need to make sure that the device you’re testing with on the other side is capable and not having it’s own issues). Also can’t tell you if the cable is have intermittent problems. If all you care about is wattage, then fine. But I find myself caring more about the supported data speeds and quality of the cable.

    But yes, I agree that cables should just be marked what they’re rated for… However it’s possible well built cables exceed that spec and could do better than they’re claiming which just puts us in the same boat of not really knowing.

    Edit: oh! and that aliexpress tester is only 4 lines(usb2.0 basically)… usb 3.0 in type c is 24 pins… You’re not testing jack shit on that aliexpress. The device I linked will actually map the pins in the cable and will find you breaks as well.




  • So am I. I’m not sure what you think wasn’t relevant. It’s a literal DoD spec. Yes that spec is outdated, but it’s still in Dban.

    You coming out of nowhere talking about how the DoD spec itself is “dead” doesn’t change the fact that it’s available and probably still used by many people out there. I’m willing to be that several companies have the old DoD spec embedded in their own SOPs. And I was always talking in the context of the contract work I did long ago which WAS to the old DoD spec regardless.



  • That was basically the workflow. On smaller drives you could do one when you get in, one at lunch and one before you left. Eventually drives got large enough that it was just once in the morning and once before leaving.

    I’ll overdo it.

    Half the contracts you didn’t know if they wanted the short wipes or long wipes. So you just do long wipes to cover your ass. It’s not like there was a rush, it was a simply menial task that became a second nature set of bashing the keyboard. Like typing some of my passwords and pins… I have no fucking clue what they are anymore… but put in front of the keyboard and I can type them by muscle memory.



  • Congrats? DBAN was made prior to 2006… IT people existed before 2006. What’s your point? You think that people just spawned into existence in 2006 with decades of IT knowledge? So like I said… “It WAS my default for a very long time because I simply defaulted to it for COMPLIANCE reasons”… eg. my contracts at the time required it and I ran boatloads of wipes.

    Regardless… DOD 5220.22-M now states

    The National Industrial Security Program Operating Manual (NISPOM) is now Part 117 of Title 32, Code of Federal Regulations.

    So let’s go look at the NISPOM stuff which says… NOTHING! So what you end up with is companies referencing the old DOD 5220.22-M because old government contracts will actually say that specific document in contracts as something that must be adhered to for a long long time. So even though it “died” on 2006, contracts may not be renewed for some time after that which still keeps the document alive.

    Now DOD 5220.22-M actually specified and defines short wipes (3 pass) and long wipes (7 pass). And in theory, could be superceded by NIST 800-88 (and probably is the default on modern contracts). And regardless of all of that… DoD internally has it’s own standards, which after wipe often requires degaussing or outright destruction of the disk, I remember having a dedicated device for it that would document serials and stuff. I’d have to pull up my army documents to remember which specific rules required that type of stuff, but I’m not going to dig out shit from 2010 just to argue with someone on lemmy.

    So I guess this boils down to… The world didn’t spawn into existence in 2006. People are older than 2006 and are allowed to talk about their experiences from before the “old times”.

    Edit: And in current contracts… all our shit is NVMe and secure erase. But I’m willing to bet muscle memory would still kick in for me if I saw the DBAN screen.
