To be a little pedantic, the usual zstd levels are positive integers (1-22 default 3). The negative integers denote "fast" modes with worse compression (there are only a few of these).
On-site natural gas turbines at a handful of DCs are genuinely loud. In general I agree that DCs are mostly fine neighbors, but maybe louder power plants aren't.
Yeah this is it. You can make really nice datacenters that are basically quiet and environmentally perfect.
This was never in dispute.
But that is not how corporations roll. They want the cheapest shit that they can get away with. No regulations only corruption.
Which is middle of nowhere America.
they just want data centers now. most companies would rather use solar, but they can't on short timelines due to land use regulations (and import tariffs)
If they can be deployed in low-earth orbit with nobody working on them, they can be deployed 20 miles east of Bumfuck, Nebraska with nobody working on them.
The point is that if you don't put them in the middle of somebody's neighborhood, nobody will care to attack them.
The idea of building robust, lightly-staffed technical facilities in obscure places all over the country is nothing even remotely new. It's how the long-distance telephone network was constructed and successfully operated in the decades before satellites took over: https://telephoneworld.org/long-distance-companies/att-long-...
Evaporative cooling consumes less expensive electricity than air conditioning. Electricity is much more expensive than water (for the same cooling load) in most places DCs are located.
You have to design your hardware to tolerate being run in consistently hotter conditions. There's a tradeoff between cooling cost and failure rate / capex.
Doesn't look like they made the hardware more tolerant of temperature, rather they made it remove waste heat more quickly.
"NVIDIA’s thermal engineering team reworked how those components handle heat, designing cooling loops that simplify how liquid is routed to multiple high-power chips on the board using a single inlet and outlet, resulting in a cleaner tray-level cooling architecture"
AMD CPUs basically all boost up to 90°C as a relatively normal operating temperature as long as the power (and some other factors) allow it to. I assume AMDs and NVs GPUs do to, but I play mostly CPU bound games so I see mine just sitting at ~60°C under load.
Core temp though. Ambient temp is a different story, and also depends on air vs water. In fact the article suggests the difference is getting the water more directly onto the chips, no mention of running at a higher core temp.
Temperature ratings are the allowed ambient temperature. The actual silicon will inevitably operate somewhat higher, because coolers are just moving heat down a temperature gradient.
What? GP's claim is that hair provides a similar benefit. VA is simply not testing heads with hair on them -- their tests can't "show otherwise" (your claim).
> GP's claim is that hair provides a similar benefit.
GP provides no evidence for that. VA Tech not addressing it (if it's true that they don't - I have no reason to believe it) is not evidence. VA Tech also doesn't address my theory that microscopic super-intelligent aliens affect helmet response.
