You don’t pipe salt water through the data center. You have a heat exchanger that touches the salt water.

It takes more work to avoid salt buildup, but you can evaporate saltwater as a place to dump heat, and we aren’t gonna run out of saltwater any time soon. 'Course, only so many places have saltwater access.

EDIT: You evaporate enough water for cooling, you can increase rainfall somewhat in the local area, which boosts crop growth measurably. I remember reading an article about nuclear power plants that use evaporative cooling producing that effect.

The growing prevalence of clean energy raises the question of possible associated externalities. This article studies the effects of nuclear power plant development (and, as a result, the increased amount of water in the atmosphere from evaporative cooling systems) on nearby crop yields and finds that an average nuclear power plant increases local soybean yields by 2 and corn yields by 1 percent.

As @papertowels@mander.xyz said.

Historically, if you were in a noisy environment, you could get closed-back, circumaural headphones — headphones that fit around your ears and had a lot of sound-absorption padding — to help soak up the sound. I still use decent non-ANC circumaural headphones at home.

There are also some people who are more-willing to tolerate discomfort than I am who get in-ear buds, which block noise in their ear canal, and on top of that, fit ear protectors intended for industrial use, like 3M X5 Peltor ear protectors, which have even more passive sound absorption stuff than current circumaural headphones do, and are even larger.

That sort of thing works well on higher frequency sound, but not as well on low-frequency stuff, like engine noise, large fans, stuff like that.

ANC basically has microphones in your headphones, picks up on what sounds are showing up at your ear, and then tries to compute and play back a sound that produces destructive interference at your ear. That is, if you look at the sound waves, where the environmental sound is low pressure, it plays back high pressure signal, and when the environmental sound is high pressure, it plays back low pressure signal. It’s not perfect, or it could make environmental sound totally inaudible. But high-end ANC headphones are pretty impressive these days. I have a pair of Sennheiser Momentum 4 headphones — good, though not the best ANC out there in 2025, and I don’t personally recommend these for other reasons — and when they kick on, the headphones are designed to have the ANC fade in; same thing happens in reverse, fades out when you flip the ANC off. It sounds almost as if fans and the like around you are powering up and down when that happens, very eerie if you’ve never experienced it before. Even the sounds that it doesn’t do so well on, like people talking, it significantly reduces in volume.

And ANC does best with the other side of the spectrum, the side that passive sound absorption doesn’t — the low-frequency stuff, especially regular sounds like fans. So having both a lot of passive sound absorption and ANC on a given pair of headphones let the two work well together.

People often use cell phones in noisy environments, with a lot of people around, and ANC makes it a lot easier to hear music or whatever without background sound interfering. I think that it’s very likely that people will, long term, mostly wind up using headphones with ANC (short of moving to something more elaborate like a direct brain interface or something). It’s not really all that important if you’re in a quiet environment, and I don’t bother using ANC headphones on my desktop at home. But if you’re in random environments — waiting a grocery store line, in a restaurant with music playing over the restaurant’s speakers, on an airplane with the drone of the airplane engines, whatever — it really helps to reduce that background sound. ANC isn’t that new. I think that I remember it mostly being billed as useful for airplane engine noise back when, which they’re a good fit for. But it’s gotten considerably better over the years. For me, in 2025, good ANC is something that I really want to have for smartphone use.

The problem is that in order to do ANC, you need at least a microphone, preferably an array, and somewhere you need to have a model of the sound transmission through the headphones and be running signal processing on the input sound to generate that output sound. In theory, you could do it on an attached computer if you had a fast data interface, but in practice, ANC-capable headphones are sold as self-contained units that handle all that themselves. So you gotta power the little computer in the headphones. That means that you probably have batteries and at least for full size headphones (rather than earbuds) you might as well stick a USB interface on them to charge them, even if the user is using Bluetooth for wireless connectivity. And if you’ve done that, it isn’t much more circuitry to just let the headphones act as USB headphones, so in general, ANC headphones tend to also be USB-capable. My Momentum 4 headphones have all of Bluetooth, USB-C, and a traditional headphones interface, but…I just haven’t really wound up using the headphones interface if I have the other options available on a given device. Might be convenient if I were using some device that only had headphones output. shrugs

I mean, there were legitimate technical issues with the standard, especially on smartphones, which is where they really got pushed out. Most other devices do have headphones jacks. If I get a laptop, it’s probably got a headphones jack. Radios will have headphones jacks. Get a mixer, it’s got a headphones jack. I don’t think that the standard is going to vanish anytime soon in general.

I like headphones jacks. I have a ton of 1/8" and 1/4" devices and headphones that I happily use. But they weren’t doing it for no reason.

• From what I’ve read, the big, driving one that drove them out on smartphones was that the jack just takes up a lot more physical space in the phone than USB-C or Bluetooth. I’d rather just have a thicker phone, but a lot of people wouldn’t, and if you’re going all over the phone trying to figure out what to eject to buy more space, that’s gonna be a big target. For people who do want a jack on smartphones, which invariably have USB-C, you can get a similar effect to having a headphones jack by just leaving a small USB-C audio interface with a headphones jack on the end of your headphones (one with a passthrough USB-C port if you also want to use the USB-C port for charging).

• A second issue was that the standard didn’t have a way to provide power (there was a now-dead extension from many years back, IIRC for MD players, that let a small amount of power be provided with an extra ring). That didn’t matter for a long time, as long as your device could put out a strong enough signal to drive headphones of whatever impedance you had. But ANC has started to become popular now, and you need power for ANC. This is really the first time I think that there’s a solid reason to want to power headphones.

• The connection got shorted when plugging things in and out, which could result in loud sound on the membrane.

• USB-C is designed so that the springy tensioning stuff that’s there to keep the connection solid is on the (cheap, easy to replace) cord rather than the (expensive, hard to replace) device; I understand from past reading that this was a major reason that micro-USB replaced mini-USB. Instead of your device wearing out, the cord wears out. Not as much of an issue for headphones as mini-USB, but I think that it’s probably fair to say that it’s desirable to have the tensioning on the cord side.

• On USB-C, the right part breaks. One irritation I have with USB-C is that it is…kind of flimsy. Like, it doesn’t require that much force pushing on a plug sideways to damage a plug. However — and I don’t know if this was a design goal for USB-C, though I suspect it was — my experience has been that if that happens, it’s the plug on the (cheap, easy to replace) cord that gets damaged, not the device. I have a television with a headphones jack that I destroyed by tripping over a headphones cord once, because the headphones jack was nice and durable and let me tear components inside the television off. I’ve damaged several USB-C cables, but I’ve never damaged the device they’re connected to while doing so.

On an interesting note, the standard is extremely old, probably one of the oldest data standards in general use today; the 1/4" mono standard was from phone switchboards in the 1800s.

EDIT: Also, one other perk of using USB-C instead of a built-in headphones jack on a smartphone is that if the DAC on your phone sucks, going the USB-C-audio-interface route means that you can use a different DAC. Can’t really change the internal DAC. I don’t know about other people, but last phone I had that did have an audio jack would let through a “wub wub wub” sound when I was charging it on USB off my car’s 12V cigarette lighter adapter — dirty power, but USB power is often really dirty. Was really obnoxious when feeding my car’s stereo via its AUX port. That’s very much avoidable for the manufacturer by putting some filtering on the DAC’s power supply, maybe needs a capacitor on the thing, but the phone manufacturer didn’t do it, maybe to save space or money. That’s not something that I can go fix. I eventually worked around it by getting a battery-powered Bluetooth receiver that had a 1/8" headphones jack, cutting the phone’s DAC out of the equation. The phone’s internal DAC worked fine when the phone wasn’t charging, but I wanted to have the phone plugged in for (battery hungry) navigation stuff when I was driving.

Sony WH-1000XM4/5/6

I don’t have one of those, but they’re pretty popular as headphones with good ANC.

Jlab Epic Air Sport ANC

I do have those, though.

In fairness, rural America probably didn’t entirely understand the implications of said vote.

As I’ve pointed out on here before, I feel like a lot of people in mostly-Republican-voting rural American are going to be even more disappointed when they discover agricultural subsidies ending, healthcare subsidies ending that disproportionately benefit poorer, rural areas, illegal immigrant agricultural workers that farms rely on becoming unavailable, counter-tariffs that tend to target agricultural output from rural areas, etc.

I’m sorry, you are correct. The syntax and interface mirrors docker, and one can run ollama in Docker, so I’d thought that it was a thin wrapper around Docker, but I just went to check, and you are right — it’s not running in Docker by default. Sorry, folks! Guess now I’ve got one more thing to look into getting inside a container myself.

While I don’t think that llama.cpp is specifically a special risk, I think that running generative AI software in a container is probably a good idea. It’s a rapidly-moving field with a lot of people contributing a lot of code that very quickly gets run on a lot of systems by a lot of people. There’s been malware that’s shown up in extensions for (for example) ComfyUI. And the software really doesn’t need to poke around at outside data.

Also, because the software has to touch the GPU, it needs a certain amount of outside access. Containerizing that takes some extra effort.

https://old.reddit.com/r/comfyui/comments/1hjnf8s/psa_please_secure_your_comfyui_instance/

ComfyUI users has been hit time and time again with malware from custom nodes or their dependencies. If you’re just using the vanilla nodes, or nodes you’ve personally developed yourself or vet yourself every update, then you’re fine. But you’re probably using custom nodes. They’re the great thing about ComfyUI, but also its great security weakness.

Half a year ago the LLMVISION node was found to contain an info stealer. Just this month the ultralytics library, used in custom nodes like the Impact nodes, was compromised, and a cryptominer was shipped to thousands of users.

Granted, the developers have been doing their best to try to help all involved by spreading awareness of the malware and by setting up an automated scanner to inform users if they’ve been affected, but what’s better than knowing how to get rid of the malware is not getting the malware at all. ’

Why Containerization is a solution

So what can you do to secure ComfyUI, which has a main selling point of being able to use nodes with arbitrary code in them? I propose a band-aid solution that, I think, isn’t horribly difficult to implement that significantly reduces your attack surface for malicious nodes or their dependencies: containerization.

Ollama means sticking llama.cpp in a Docker container, and that is, I think, a positive thing.

If there were a close analog to ollama, like some software package that could take a given LLM model and run in podman or Docker or something, I think that that’d be great. But I think that putting the software in a container is probably a good move relative to running it uncontainerized.

Seems like it might be useful to have a per-site toggle.

I’m pretty sure that it defaults to best quality.

goes looking at man page

   By default, yt-dlp tries to download the best available quality if you don't  pass  any  options.   This  is  generally
   equivalent to using -f bestvideo*+bestaudio/best.  However, if multiple audiostreams is enabled (--audio-multistreams),
   the  default  format changes to -f bestvideo+bestaudio/best.  Similarly, if ffmpeg is unavailable, or if you use yt-dlp
   to stream to stdout (-o -), the default becomes -f best/bestvideo+bestaudio.

So I think that it should normally pull down the best audio unless you get into some situation where YouTube doesn’t offer a format that simultaneously has the combination of highest audio quality with the highest video quality; if it has to do so to get the highest video quality then, it’ll sacrifice audio quality.

EDIT: Hmm. I could have sworn that there was more text about prioritizing relative audio and video quality at one point in the man page, but I don’t see anything there now. Maybe it can just always get the best audio quality, regardless of video quality, can pull 'em entirely separately.

If your phone is Android, NewPipe is an open-source, third-party client that permits setting quality. It’s on F-Droid (the big open-source app repository) if you use that, and probably on Google Store as well.

Thanks.

EDIT: There isn’t an --embed-auto-subs, but there is a --write-auto-subs.

I’m not really following video DRM, but my understanding is that Widevine won’t run in a VM with a virtualized video card like that.

If you use Firefox:

https://addons.mozilla.org/en-US/firefox/addon/youtube-video-quality/

Fair enough.

I mean, you don’t need anything; it’ll work with no flags. I have these:

$ cat ~/.config/yt-dlp/config
--embed-subs
--embed-metadata
--embed-chapters
--embed-thumbnail
--sponsorblock-mark=all
$

That’ll just embed some useful metadata in the file.

You might try again. I was blocked for a couple weeks after I pulled a bunch of videos from a channel using yt-dlp, and for a while YouTube required an account (which I will not get) from that IP. But a couple weeks later, things were working again.

If Google really wants to, they can crack down on yt-dlp, and I assume that if enough people are using it, they’re likely to do such a crackdown. Like, this works for the moment, but…

Nebula seems like it has the same types of videos I like to watch.

I mean, Nebula is commercial service and I assume that they’d profile, the same as YouTube. Like, if you’re okay with that, you can get YouTube Premium.

Of course, I can get into PeerTube as well.

I’m still skeptical that this is going to scale sufficiently either in bandwidth or in amount of content.
