  • In the US at least, most equipment (unless you get into high-and datacenter stuff) runs on 120V. We also use 240V power, but a 240V connection is actually two 120V phases 180-degrees out of sync. The main feed coming into your home is 240V, so your breaker panel splits the circuits evenly between the two phases. Running dual-phase power to a server rack is as simple as just running two 120V circuits from the panel.

    My rack only receives a single 120V circuit, but it’s backed up by a dual-conversion UPS and a generator on a transfer switch. That was enough for me. For redundancy, though, dual phases, each with its own UPS, and dual-PSU servers are hard ro beat.



  • Speaking from experience, be careful you don’t become over-zealous in your anti-scraping efforts.

    I often buy parts and equipment from a particular online supplier. I also use custom inventory software to catalog my parts. In the past, I could use cURL to pull from their website, and my software would parse the website and save part specifications to my local database.

    They have since enacted intense anti-scraping measures, to the point that cURL no longer works. I’ve had to resort to having the software launch Firefox to load the web page, then the software extracts the HTML from Firefox.

    I doubt that their goal was to block customers from accessing data for items they purchased, but that’s exactly what they did in my case. I’ve bought thousands of dollars of product from them in the past, but this was enough of a pain in the ass to make me consider switching to a supplier with a decent API or at least a less restrictive website.

    Simple rate limiting may have been a better choice.


  • I still enjoy the second-wave stuff from time to time, but you’re absolutely spot-on with what’s been coming out in recent years. I’m really into groups that have kept the original BM music style but embraced modern production. A few that come to mind are Faidra, Spectral Wound, Asarhaddon, and Funeral Winds; fantastic bands that play “true” BM but have good recording quality.

    Like you mentioned, the big change is just how many “crossover” bands there are, and I’m all for it. You didn’t ask for suggestions, but I’m going to offer some of my favorites anyway:

    • Harakiri for the Sky - One of the best post-black bands.
    • Anomalie (shares members with Harakiri for the Sky) - BM plus what I can only call “tribal” elements.
    • Psyclon 9 (at least their older albums) - BM plus industrial/aggrotech.
    • Dawn of Ashes - See above.
    • Anaal Nathrakh - BM + grind + industrial + ?
    • Darkthrone (yes, THAT Darkthrone) - Blackened hard rock? I don’t know what to call their new stuff, but it’s not bad.
    • Gaerea - Radio-friendly BM
    • Kanonenfieber - Blackened melodic death metal? Maybe?
    • Afsky - Folk-inspired BM. Seems like this is a really popular combination.
    • None - DSBM, but with the exception of their filler tracks, more on the BM, less on the DS.
    • Ernte - Fairly traditional BM, but with female vocals.

  • I will never buy a Tesla. I’m not normally one to pay attention to brands, but Elon Musk has tainted the brand to such a degree, that I’m disgusted at the idea of being associated with it.

    That being said, the company still makes some decent technology. From what I understand, the motors, motor controllers, and battery packs are fairly decent pieces of kit. There seems to be some kind of disconnect between their engineering teams, though, because the cars themselves are so bad. I’ve seen internal panels fall off, interior components break at the slightest touch, misaligned body panels, and any number of other fit-and-finish issues. Not to mention, every single one is hideous. Make them look like an EV or make them look like a luxury car, not some half-assed abomination between the two.

    I have to wonder why there’s such a disconnect within the company. It feels akin to building a Ferrari drivetrain and installing it in a Kia.









  • I think you could make an argument that even burning plastic in a firepit vs sending it to a landfill are roughly equal. Climate change and air pollution are both major issues, but so is plastic waste and microplastics working their way into everything. I have no idea of the overall harm of burning plastic is less than throwing it away; they both pollute the environment. I can see the the logic in thinking burning is a viable alternative.

    Ideally, though, people would just stop using disposable plastic. Plastic is a fantastic material, but it was never supposed to be for “use once and discard” items. For creating durable objects with a decent lifetime, sure, use plastic. Don’t use it as wrapping over another plastic object.


  • I did some research on this, and it turns out you’re absolutely correct. I was under the impression that ECC was a requirement for a ZFS cache. It does seem like ECC is highly recommended for ZFS, though, due to the large amount of data it Storrs in memory. I’m not sure I’d feel comfortable using non-ECC memory for ZFS, but it is possible.

    Anecdotally, I did have one of my memory modules fail in my TrueNAS server. It detected this, corrected itself, and sent me a warning. I don’t know if this would have worked had I been using non-ECC memory.


  • One thing to keep in mind if you go with an i5 or i7 is that you won’t have the option to use ECC memory. If you’re running TrueNAS, you’ll need ECC memory for the ZFS cache. A Xeon E5 v2 server is old, but still has a more than enough power for your use case, and they’re not particularly expensive.

    If you need something more powerful, you can find some decent Xeon Gold systems on eBay, but they’ll be a bit more pricey. The new Xeon W chips are also an option, but at least for me, they’re prohibitively expensive.



  • I decided to give up on it. Looking through the docs, they recommend that due to “reasons,” it should be restarted at least daily, preferably hourly. I don’t know if they have a memory leak or some other issue, but that was reason enough for me not to use it.

    I installed TubeArchivist, and it suits my needs much better. Not only do I get an archive of my favorite channels, but when a new video is released, it gets automatically downloaded to my NAS and I can play it locally without worrying about buffering on my painfully slow internet connection.
