Comment skeptical astrophysicist (Score 2) 21

From the cited article;

Sean McWilliams, an astrophysicist at West Virginia University, was skeptical that the gravitational wave frequency analyzed by the scientists was actually "dictated" by the event horizon.

For this reason, "the actual observed signal doesn't really tell us anything about the horizon or the other properties directly related to it," he told AFP.

Comment lowball (Score 1) 39

I was wanting to sell a car recently, a nice one with low miles and in great shape. I went to the Carvana website and got a low quote. I was showing it at local dealerships and went by to see them as well, maybe they would do better if they saw the car and drove it. Nope, whatever the website said it was worth is what they would pay.

Eventually I was offered about 50% more elsewhere, a decent price and I'm sure they sold it at a profit.

Submission + - Why AI token prices are about to plummet (businessinsider.com)

ZipNada writes: The main force driving token prices lower is a new wave of technology that's sweeping through AI data centers.

Nvidia's Blackwell GPUs are being installed in huge volumes right now. By the second half of this year, these systems, which are really supercomputers rather than chips, will be operating at scale, helping AI labs train new models and run them more efficiently.

These systems took a while to install properly, partly because they needed to be water-cooled and required other gnarly new data center setups. But the payoff could be huge.

50 x more, 35 x cheaper
SemiAnalysis, a respected AI research firm, compared Nvidia's top Blackwell system, the GB 300 NVL72, to Nvidia's previous system, called the Hopper HGX 200.

With the older system, each GPU generated 90 tokens per second, while the new Blackwell system generated 6,000. That's 65 times more.

>> "Build it and they will come" seems to have been the entire planning of how to power and cool these centers.

Bullshit. The local data centers here in Texas underwent an extensive review process. They are sited near high voltage lines and get power directly from there through power purchase agreements. They use closed-loop cooling.

There's a lot of local opposition to them but it has been pumped up by misinformation similar to what you are repeating. One data center in Truckee California may have bought all the local electricity but that doesn't apply to the entire industry.

>> take up local water at below cost

I did some checking on the local data centers here in Texas. The use closed-loop cooling, and therefore use very little water. There's no sign that they have caused electric bills to rise. They are sited in designated industrial zones or on the outskirts of town where noise will not be a problem.

>> What benefit does it provide them???

They pay taxes. One of them I looked at will be paying about $7 million over the next 10 years.

Comment good competition (Score 1) 36

The AI companies are competing for market share at present, but it isn't very surprising to see prices for the top models ramp up as they become more complex and use more compute resources. But there's a long trail of older, lesser models still available and some of them are pretty good. My suspicion is that casual users can do just fine with relatively inexpensive mid-or-low-tier models.

I use AI most every day for technical work (to great benefit, I'm often amazed). A couple of months ago the vendors started rationing the token consumption as they reach the limits of their existing compute infrastructure. Now I have to adjust the models I use based on what I'm trying to accomplish at the moment in order to economize. The hard stuff goes to models that are very good but at least a generation behind the very expensive cutting edge. Things that are more mundane can be allocated to older and cheaper models. Sometimes they struggle with a task and I have to bump up to something better. Yesterday I used up my daily token quota after a few hours of very productive work, a bummer but its understandable.

>> I can't imagine why.

It's because there's a vast amount of cheap, available land there. Data centers are generally built out in the boonies, but near enough to a town that the employees can have a decent place to live and shop. Adjacent to a hefty power line is also a requirement.
