  • 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.



  • corroded@lemmy.worldtoTechnology@lemmy.worldIs Microsoft trying to commit suicide?

    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 will resort to ChatGPT for coding help every so often. I’m a fairly experienced programmer, so my questions usually tend to be somewhat complex. I’ve found that’s it’s extremely useful for those problems that fall into the category of “I could solve this myself in 2 hours, or I could ask AI to solve it for me in seconds.” Usually, I’ll get a working solution, but almost every single time, it’s not a good solution. It provides a great starting-off point to write my own code.

    Some of the issues I’ve found (speaking as a C++ developer) are: Variables not declared “const,” extremely inefficient use of data structures, ignoring modern language features, ignoring parallelism, using an improper data type, etc.

    ChatGPT is great for generating ideas, but it’s going to be a while before it can actually replace a human developer. Producing code that works isn’t hard; producing code that’s good requires experience.





  • I really think this depends largely on who you are and what you do with your phone. I have face recognition and fingerprint recognition both enabled on my phone. It’s good enough to prevent a thief from gaining access to my device, and if law enforcement asked, there’s nothing on my phone that could possibly be incriminating. Realistically, I’d have no issue just unlocking my phone and giving it to a police officer, although I do know well enough to always get a lawyer first. Biometrics add an extra layer of convenience; it’s nice to just look at my phone and it unlocks. My concern personally is more about someone stealing my phone and accessing my accounts than self-incrimination.

    If I ever was going to put myself in a situation where I’d run afoul of the authorities, I’d leave my phone at home anyway.



  • 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.



  • 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.”


  • I end up appreciating my once-in-awhile automations more.

    I can definitely understand this. One of my automations monitors a water sensor at the base of my water heater and under the kitchen sink (has leaked before). If it triggers, all my lights in the house turn on, any colored bulbs turn red, and they flash on/off each second. It hasn’t triggered yet (thankfully) except for testing, but the peace of mind is fantastic.



  • 4 Mbit is exceptionally slow by today’s standards; when I signed up for internet access (there’s only one provider available where I live), I told them “I will pay for whatever the fastest connection is that you can offer.” Turns out that’s just single-channel DSL. They won’t even install bonded DSL where I live, and believe me, I’ve tried. I do have Starlink as well, but because of the land around me, it’s always going to be obstructed by the land topology; when I calculated how high I would need to raise my antenna to avoid obstructions, it was several hundred feet. My pfSense box does a good job of routing traffic between my DSL connection and my Starlink connetion (and falling back when Starlink is obstructed), but for hosting anything, I need a stable connection. That leaves me with just my DSL connection.
