  • 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.



  • Microsoft knows that the addition of adds to Windows, Recall, data mining, etc are not suicide. As far as tech news goes, Lemmy really exists in an echo chamber. The vast majority of us at least have some interest in technology. For the majority of the population, though, this isn’t true. The typical person sees a computer as a tool to be used for other things. They’re not reading articles about the latest release of Windows, new CPU technology, the latest GPU, etc. They’re using their computer, and when it’s time for an upgrade, they buy whatever suits their needs.

    If I was to ask any of my family, or most of my coworkers, about any of the latest “controversies” surrounding Microsoft, they would have no idea what I was talking about. Microsoft obviously thinks that the added profits gained by monetizing their customers will offset the loss of 1% of their users that switch to Linux. They’re probably right, too.

    I like Windows, personally (well, Windows 10 at least). My unofficial rule has always been if it needs a GUI, then it runs Windows, otherwise, it runs Linux as a headless machine. Once Windows 10 is no longer a viable option, my unofficial rule will be “it runs Linux.” Most people will not make this switch.


  • I certainly don’t think it will be easier in a few years, but I also think that after 19 years of using gmail, a few more years aren’t going to make a huge difference. It’s really kind of sad to think about how far Google has fallen. I started with gmail in 2005. At the time, Google was starting to become the “go-to” search engine. They had better results than Yahoo or AltaVista; the “do no evil” slogan was also a great “feel-good” factor. I don’t think anyone at the time expected how different things would be in 2024.

    I can host my own media on my own server. I use Nextcloud Talk for IMs (also hosted on my own server). Just about any online service can be self-hosted, except for email. I have certainly tried in the past, even hosting email on a VPS. You run into so many issues, though. Your server isn’t trusted, websites don’t recognize your domain, a whole litany of problems. Email is just one of those things that you really can’t self-host.

    Sure, I could switch to a new email provider, forward gmail, and slowly over time update my email address for everyone who’s sending to my gmail account. What happens then when my new email provider decides to start harvesting my data for profit? Email is one of those things where you can’t live without it, but you’re forced to use a service that isn’t your own and could fuck you at any time.




  • I have heard the same thing about ACs, but I think it depends on the unit. The window units that I use have a switch on the front that literally just turns them off; there’s no delay time for the compressor. It’s the same as pulling the plug.

    I’ve used single and dual-hose portable ACs in the past, and I only have dual-hose units now. This is purely anecdotal, but when I had single-hose units, they would maintain the temperature throughout the day as it warmed up, but they didn’t do a great job of cooling. A dual-hose AC with a similar capacity was actually able to lower the temperature.



  • 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.



  • This is a really interesting question. I remember a lot of very niche PCI (not PCIe) cards from the old days.

    My current-day boring use-case: Multiple GPUs that have never once been used for gaming. One is an A2000 card that does video transcoding and tone mapping for Jellyfin. The other is an old Quadro card that handles encoding/decoding for my NVR.



  • Thanks! I really enjoyed setting it up. The main part of the automation consists of two template sensors: One that monitors temperature, humidity, illuminance, and wind speed and produces an “apparent” temperature. The other monitors the apparent temperature, does all the math and colorspace conversions, and produces RGB values for the bulb. It was by far the most difficult automation to set up, but it was a great way to get better and programming templates.


  • I have a motion sensor that turns on the bathroom light when you enter, then turns it off after no motion is detected for 5 minutes. Works great except for those long sessions on the toilet; nobody likes to poop in the dark. Now I have a door sensor on the bathroom so when no motion is detected, it turns off the lights after 5 minutes unless the door is closed, then it’s 30 minutes. Much better than having to wave your arms around every 5 minutes when you’re trying to take care of business.



  • I use a lot of sunset/sunrise automations, but one of my favorite is for the lights on the main floor of the house. They turn on with a motion/presence sensor when someone enters the room, but the intensity of the light and the color of the light are controlled by the sunrise/sunset times. During the day, they turn on at 100% brightness and a cool white; starting 1 hour before sunset and 1 hour before sunrise, they scale between 100%/cool white and 60%/warm white. You don’t notice it unless you’re really paying attention, but it really helps the house feel a lot more “cozy.”
