rsync is a fine tool, but it’s not really for backups. It’s for unidirectionally syncing data, which is part of a backup.

There are tools that use librsync to do a backup system, like rdiff-backup or duplicity.

I have used rdiff-backup in the past, but restic supports deduping data keyed off content rather than filename, which is functionality that I rather like having. I drive a restic job from backupninja, which handles doing things like notifying you if a backup has failed.

I’m not personally familiar with Synology’s products, but if what’s going on is that you’re using some built-in feature of a Synology NAS to copy files from a USB drive to the NAS and seeing an error, I’d probably try copying that particular file to somewhere else on a PC, cutting the NAS out of the loop, to make sure that you don’t have, say, a corrupt filesystem where attempts to read the file contents are failing.

The limiting factor is in significant part memory and to a lesser degree storage, and while in some cases, there are options for PCs — like using scavenged DDR4 DIMMs — that aren’t available for consoles, PC prices have also generally been hit by the same factors that have driven up console prices.

Sure, I’d like that, but I’m not going to keep personally fighting to make life better for that manufacturer’s customers. Not when there are other car manufacturers that aren’t pulling that stuff that people can be directed to.

Is the message you want to send “if you buy product from a vendor who actively goes out of their way to dick over open-source developers, it probably won’t matter for me as a customer because those developers will keep expending time and accepting legal risk to try to improve the situation for those customers”? Or do you want it to be “you probably want to look for open-source friendly manufacturers”?

I don’t really see the point. I mean, why bother to try to do something that just makes the company’s printers more desirable? Even if you “win”, the company is going to be a pain in the ass. Do you really want to waste time and financial resources on improving the company’s product?

Just don’t buy Bambu Lab printers. Don’t recommend them. And don’t support them with software.

If this was a world in which there was one 3D printer manufacturer, it’d be different, but it’s not. They have competition.

but it literally is just Thacker Pass.

This isn’t Thacker Pass.

https://en.wikipedia.org/wiki/Thacker_Pass_lithium_mine

The Thacker Pass lithium mine is a lithium clay mining development project in Humboldt County, Nevada

The location being discussed:

McDermitt Caldera in Oregon

It looks like there was some discussion that there might be lithium there a bit back, like in 2023, but this is not decade-old news.

And…let me make it even more concrete. I’d say that there are basically two scenarios:

1. We establish that AI — for some definition of AI — is simply too dangerous for humanity to have. In that case, the right path is to ban AI globally. That means that nobody gets it. Some coalition of countries is going to have to be willing to attack anyone who tries developing it. In that case, what we have is effectively an arms control restriction baked into customary international law. It is not optional to participate. And, for all the future of humanity, we need to be willing to enforce that. It means that we need a viable verification protocol to ensure that nobody is developing it, as is normally the case for arms treaties. And everyone has to submit to that verification protocol.

2. We don’t. In that case, we want to develop AI sooner rather than later.

I am certainly not willing to say that #2 is the “right” scenario and #1 is the “wrong” one. But if we decide on #1, that comes with a lot of things that we need to be doing as a species. It’s not just going to be the pre-computer-era status quo persisting, where our limited state of technology was what maintained the situation.

EDIT: I’d also add that, just as that I’m not sure that Friendly AI is a solvable problem, I’m also not sure that it’s really viable to have a verification protocol where we can prevent development of AI. Past arms control treaties where I think that verification was likely much easier — it’s hard to hide development of major warships under the Washington Naval Treaty, for example, yet there were still parties evading restrictions — were not always successful. #1 comes with its own set of hard problems too. Are parallel compute processors legal? What about their development and production? Under what restrictions are they used? Is it possible to achieve advanced AI using CPUs (my guess is that it likely is)? If so, what new restrictions will need to be placed on use and access to CPUs? How will we identify entities building production facilities to build CPUs and GPUs? Will we need to track all existing CPUs and GPUs, to try to identify entities who might be stockpiling them? How will we monitor what the great stores of those out there now are being used for?

If we go with #1, that also entails a different world from the one that we live in today.

I’ve got some pessimistic views as to long-term AI concerns — I’m not sure that aligning advanced AI goals with human goals in the long run is a viable problem to solve. We may not be able to achieve Friendly AI. I could believe that.

But I certainly don’t think that AI development is “moving too fast”. Not really anything to gain in slowing down development. I remember Elon Musk proposing a six-month moratorium on development — that doesn’t make any sense, only would be something that you’d want to do if you had an immediate milestone that you believed that there was major risk attached to. In general, either AI is something that you should ban globally because it’s too much of an existential risk for humanity, and halt all development and enforce that halt, or you’d like to achieve it as soon as possible. We are not at a point where there is a consensus that that level of unacceptable risk exists and there is a global commitment to enforcing such a global prohibition.

I can believe that there might be an excess of infrastructure development in particular, that we might not have the research side moving as quickly as need be to support that. Like, we might be doing misallocation in buying a lot of specific chips without establishing that those chips are going to provide a worthwhile return. But in terms of the technology advancing…no, can’t agree there.

Does Kickstarter have liability in general for Kickstarted projects? I’d kind of assume that that’s on the specific project. I can’t imagine that Kickstarter is in any kind of position to really do a domain-specific evaluation of whether a given project is in line with local regulations.

First, Peltier elements are pretty inefficient. Second, I’m dubious about the design — a Peltier element moves heat from Point A to Point B, and the whole device appears to still sit beneath the shirt. I suppose that the hot side is the outer side, but what you’d ideally want is to have hot air blowing as far away from you as possible.

I’m skeptical that it’s better to carry a battery-powered Peltier element than to carry something like an evaporative cooler. That’s more-energy-efficient, and you don’t have the problem of part of the device getting hot.

EDIT: Or, if you can’t leverage phase-change from liquid water to water vapor because of high humidity, cooling vests that leverage solid to liquid phase-change.

China’s special for controlling a very high proportion of the processing infrastructure that converts the lithium ore to batteries, rather than the extraction. There are a bunch of places that have substantial known lithium reserves.

https://worldpopulationreview.com/country-rankings/lithium-reserves-by-country

Australia does the most extraction:

https://worldpopulationreview.com/country-rankings/lithium-production-by-country

Given that the Metaverse stuff hasn’t been commercially successful thus far, burning a lot of money.

The Oregon Chapter of the Sierra Club indicates they support cleaner energy but believe drilling must not come at the expense of fragile habitats.

Foreign lithium isn’t magic, zero-footprint lithium. We are a major consumer of lithium, and will probably increase if we’re going to move to BEVs. If we’re going to consume it, it only seems fair to the rest of the world to have some of the footprint in our own territory.

I’d kind of expect more than that.

Meta’s said that they’re going to to be shifting focus from VR to AI.

It looks like Meta’s VR wing employs 15,000 people:

https://en.wikipedia.org/wiki/Reality_Labs

Number of employees: 15,000 (2026)

Though…hmm. It says that there are some AI things under that as well, so maybe that’s not all VR:

Reality Labs, formerly Oculus VR, is a business and research unit of Meta Platforms (formerly Facebook Inc.) that produces virtual reality (VR) and augmented reality (AR) hardware and software, including virtual reality headsets such as the Quest, and online platforms such as Horizon Worlds. In June 2022, several artificial intelligence (AI) initiatives that were previously a part of Meta AI were transitioned to Reality Labs.

“The inability to access the content of encrypted communications constitutes a major obstacle for the work of the justice system and intelligence services,” the delegation wrote, framing end-to-end encryption as a problem to be solved rather than a protection to be preserved.

Senator Cédric Perrin, who chairs the foreign affairs committee and sits on the intelligence delegation, has been pushing this fight for over a year. During debate on a narcotrafic bill, he secured an amendment that would have forced messaging platforms to “implement the necessary technical measures in order to allow intelligence services to access the intelligible content of communications and data passing through them.”

I mean, I can send a GPG-encrypted message over a messaging platform and you can recover it if you want even if that platform’s native encryption is backdoored, but you’re still just looking at an end-to-end encrypted message.

Desktop PC with a lotta hard drives in it and big fans that don’t have to spin fast and make a lot of noise.

I use a USB DAS JBOD enclosure with fans, which is also an option if you have a mini-PC and just want a bunch of drive space.

https://www.amazon.com/dp/B0DCDDGHMJ

This particular enclosure has physical buttons that lock in place so that the power state is restored on power loss, something that (to my surprise) a number of USB DAS enclosures apparently don’t do.

You could try reducing the fan speed. That might be okay, if the hardware doesn’t actually need the cooling. If the BIOS has fan curves, go fiddle with that. If it doesn’t, dedicated fan controllers do exist.

If the server is a standard ATX motherboard and if your rack has vertical space, you can also probably get a new ATX case of whatever sort you want, preferably taller, and get something with larger, slower fans and transplant the hardware. A lot of rack servers are vertically-cramped to let a datacenter put as many in a rack as possible, so you get stuff like 1U machines with those dinky 30mm fans. In general, the larger the fan, the less noise per airflow.

searches

https://www.amazon.com/RackChoice-Mini-ITX-Rackmount-Chassis-Standard/dp/B0D296DVD8

I’ve never used that, but it’s a 3U and has three 120mm fans.

If you don’t care about cost, there are also sound-isolated racks. These have some sort of sound-blocking material like plywood on the outside and sound-absorbing foam on the inside. I have been interested in these in the past, because I would like one, but everything I’ve seen has been absolutely obscenely-priced, probably because datacenters don’t care about noise, and few people are running racks in homes or offices. I doubt that the people that sell them get much volume.

EDIT: Example sound-isolated rack:

I don’t think I’d say “inevitable”. Possible, maybe.

https://en.wikipedia.org/wiki/Splinternet

The splinternet (also referred to as cyber-balkanization or internet balkanization) is a characterization of the Internet as splintering and dividing due to various factors, such as technology, commerce, politics, nationalism, religion, and divergent national interests. “Powerful forces are threatening to balkanise it”, wrote the Economist weekly in 2010, arguing it could soon splinter along geographic and commercial boundaries.[1] The Chinese government erected the “Great Firewall” for political reasons, and Russia has enacted the Sovereign Internet Law that allows it to partition itself from the rest of the Internet.[2][3] Other nations, such as the US and Australia, have discussed plans to create a similar firewall to block child pornography or weapon-making instructions.[1]

Clyde Wayne Crews, a researcher at the Cato Institute, first used the term in 2001 to describe his concept of “parallel Internets that would be run as distinct, private, and autonomous universes.”[4] The concept itself dates back at least to pair of articles in the journal Science and at the International Conference on Information Systems by Marshall van Alstyne and Erik Brynjolfsson in 1996 and 1997.[5][6] They argued that it the Internet and related technologies “have the potential to fragment interaction and divide groups by leading people to spend more time on special interests and by screening out less preferred contact.” They dubbed this effect “cyberbalkanization” and developed a set of formal measures.[7]

Crews used the term in a positive sense, but more recent writers, like Scott Malcomson, a fellow in New America’s International Security program, use the term pejoratively to describe a growing threat to the internet’s status as a globe-spanning network of networks.[8]

Virtually all of these are temporary moratoriums, most-likely to let the city examine impact of some proposed development and gather feedback.

There are three permanent bans in force:

• Pemberton Township, New Jersey (27k people)

• Warrenton, Virginia, specific 42-acre area (10k people)

• Weaverville, North Carolina (4.5k people)

St. Charles, Missouri is also listed as permanent, but the text says that there is a temporary moratorium with a proposed permanent ban.

Note that this and most of the others do not appear to be specific to anything AI-related; this is all data centers.

One other note: One of the first conversations on here I had was when Ada, the lemmy.blahaj.zone admin, was talking to some gay guy in some Middle Eastern country where content related to homosexuality were banned. The lemmy.blahaj.zone instance was blocked at his country’s network, but he could view the text content from any other home instance (since any accessible home instance on the Threadiverse itself intrinsically basically acts as a proxy for the content on other instances). I remember pointing out that he could tunnel via SSH. His problem was that he couldn’t view images, since the images were hosted on the lemmy.blahaj.zone server, but these days, some lemmy home instances (including my home instance, lemmy.today) automatically locally proxy images posted elsewhere to hide the IP address of their users, so he wouldn’t even have that problem now.
