Comment Re:Easy Fix... (Score 1) 37

Especially when basically all methods of sabotaging cables(except possibly very near shore) are 'remote'/disposable; if only at the tech level of 'put anchor on rope because water deep'. Nobody is going to give a damn about losing an inert metal chunk.

Reportedly, none of that is public, the business of tapping a fiber line underwater is considerably more fiddly, and enough mines might make that a hassle; but it would also make install and repair far more expensive and probably just theatre when you consider the risk that someone at the telco isn't updating their ASAs.

Comment Yes, AI is thinking (Score 1) 219

The transformers used by LLMs discover and encode the relationships between words IN HUMAN THOUGHT EXPRESSIONS. The multi-layer nature of the deep neural net into which the transformers encode these relationships results in increasing levels of abstraction of the relationships being encoded in different layers of the neural net, along with the ways and strength that each more abstract relationship-aspect is involved in each more particular relationship. By focus on contextual relationships that humans attend to in their communications, and by having the ability to capture abstract aspects of the relationships, the LLM is effectively learning a semantic network of the concepts that words and word sequences utttered by humans represent. The carefully hierarchically organized and represented statistical properties of human syntax (when averaged over many many uttereances so as to ignore accidental, non-essential differences in expression) ultimately result in a usable (cheaply associatively tourable) representation of the semantics (MEANING) behind human communications. i.e. a general and specific knowledge base has been represented in the deep neural net.

It is then possible to design and implement various query-driven and goal-directed associative touring algorithms to visit the concepts in the knowledge base in appropriate touring orders (nearby concepts are nearby in the neural net representation, more general ones are "above", more specific ones are "below") so that we could say these algorithms are thinking abouit the queries and appropriate answers to them.

I think the parent commenter was proposing an analogy to the various temples-overtaken-by-jungle and cathedrals-and-hovels societies; where the competing c-suites of the magnificent seven and aspirants suck our society dry to propitiate the promised machine god.

I have to say; datacenters will not make for terribly impressive ruins compared to historical theological white elephant projects. Truly, the future archeologists will say, this culture placed great value in cost engineered sheds for the shed god.

Comment Re:Air cooling (Score 1) 26

At least for new builds/major conversions; it's often a matter of incentives.

There's certainly some room for shenanigans with power prices; but unless it's an outright subsidy in-kind you normally end up paying something resembling the price an industrial customer would. Water prices, though, vary wildly from basically-free/plunder-the-aquifer-and-keep-what-you-find stuff that was probably a bad idea even when they were farming there a century or two ago; to something that might at least resemble a commercial or residential water bill.

If the purpose is cooling you can (fairly) neatly trade off between paying for it in power and paying for it in water; and when the price differs enormously people usually choose accordingly if they can get away with it. In the really smarmy cases they'll even run one of the power-focused datacenter efficiency metrics and pat themselves on the back for their bleeding edge 'power usage effectiveness'(just don't ask about 'water usage effectiveness').

You can run everything closed loop; either dumping to air or to some large or sufficiently fast moving body of water if available; but the electrical costs will be higher; so you typically have to force people to do that; whether by fiat or by ensuring that the price of water is suitable.

Theoretically, but in practice SMRs won't be useful for that. They still need a large and robust containment building, and nuclear grade security around it. They need a cooling pool or guaranteed supply of water.

A more practical idea for small fossil fuel stations is to turn them into spinning mass, to help provide inertia and a bit of energy storage. Or turn the site into a battery.

They will just throw Rolls Royce some money to muck about with SMRs, before realizing what everyone already knows - they aren't better than traditional reactors, and nuclear in general is the most expensive form of energy we have.

Naturally the taxpayer and consumers will be on the hook for all this.

It's not a solution for non-technical people, but can you use Cloudflare Zero Trust or similar for Plex?

I have my own Subsonic music server at home, using Navidrome. I set up Cloudflare Zero Trust so I can access it remotely via the web, with a secure Google login in front of it. You can use other authentication methods, it doesn't have to be Google. Passwords, 2FA, certificates, other providers.

For desktop, any browser works. For mobile I use Symfonium. It's not free, it's a cheap one-time purchase, but it works great with that set-up and means I can stream my music anywhere, without the need for a VPN.

What's changed is that in the early days flash memory was one bit per cell. Now most consumer grade stuff is multi level, so instead of a single threshold voltage that separates a 1 from a 0, there are multiple thresholds that each represent a different binary code.

SSDs sometimes have to re-read blocks with different voltage thresholds to get good data, and make use of error correction on top.

Presumably age related degradation is worse for multi-level flash.
