Comment Re:Seems like a waste of time and money (Score 2) 66

About 40 years ago a friend of mine stated that this problem had been solved and that slow motion photography proved that the cat used its tail to right itself. I actually had a tailless cat nearby (lost it in an accident with a car) which I retrieved, held out in front of him about two feet off the ground, and let go. It landed on its feet.

What's curious is how long this has been "studied" and how many different theories there have been!

Comment "bright as a full moon" (Score 3, Insightful) 80

You can stare at the full moon all night if you like, because the albedo of the moon has filtered most of the light including the UV band that naturally passes through our own atmosphere. The three mile circle illuminated by a mirror would bounce a significantly higher amount of UV than the moon's albedo. If you treat the 60ft reflector as an analog to a pinhole in a pinhole camera, the circular area on the Earth surface would be a rough projection of the image of the sun.

(1) I wonder how they calculate the UV exposure for the observer on the surface within the illumination area.

(2) I wonder if you'd be able to detect places in a coherent projection where sunspots or coronal ejections are reflected through the "pinhole" effect of this arrangement.

Comment Backlog (Score 4, Informative) 17

I can't speak to all of the areas that contribute to AI backlog (like capital allocation, systems integration, networking availability, etc). But from a data centre standpoint it is a real struggle. The general timeline to get from requirements to signature on a data centre lease is about three months if all goes well (assuming you are not self-performing). Once that is signed a DC project takes about two years from conception to RFS (ready-for-service) where you can start rolling in racks. A LOT goes into that timeframe: Ordering LLE (Long-Lead Equipment (generators have a 24+ month lead time right now)), securing permits, securing power, securing a EOR (Engineer of Record) and getting the design done, land preparation, construction crews and materials, etc.

And that is all just to get a "powered shell": what we call a building with at least two diverse sources of utility power, gens, transformers, power switch gear, static UPSs (if they are being used), chillers, pumps and piping, etc. You still can't roll in racks until you have a fit-out design (PDUs, RPPs, whips, busway, FWUs (Fan Wall Units) or CRAHs (Computer Room Air Handlers), temp and humidity sensors, etc. It takes about a YEAR from the time you get the fit-out design to the time when you can roll in racks (but it is possible to line up fit-out works with RFS if you get the design early enough).

Everybody is looking for some creative solutions to speed things up, but data centre deployments are complex (I deal with well over 1000 individual requirements per project) and there are a lot of supply chain constraints. Most of the hyperscalers are juggling 20+ simultaneous projects, it's burning people out and there is a lot of churn in the business (making it worse).

The Trump administration just pushed out the official who's unit banned Chinese vehicles.

"Jan 23 (Reuters) - The Trump administration has pushed out a Commerce Department official whose office effectively barred nearly all Chinese cars from the U.S. market for national security reasons, according to people familiar with the matter."

"The sources said that, had she not resigned, Cannon would have been reassigned, and that the new administration plans to put a political appointee in the post. Her last day is expected to be February 20, two people said."

Why this is happening is anyone's guess.

It's almost as if we shouldn't have included "intelligence" in the actual fucking name. But once again our language has been co-opted by marketing BS and now here we are trying to set the record straight so people aren't confused or deceived.

Comment Grand Cultural Errors (Score 1) 259

As early as the 1950s, critics of the establishment's public education system said its main purpose was to produce a contented and functional workforce. And they were right. They were so right that even they themselves did not understand the full implications: they were so right that it ultimately made them wrong. And then they won, and we are facing the consequences. Not just since 2013: Arne Duncan was indeed an unmitigated disaster for American education, but much of the problem is older than him. And no one is willing to admit that what came before worked better.

The most useful feature for the same people who use text messaging and emergency services when they are outside of a cell coverage area is a local weather forecast. Something that the Garmin In-Reach family of devices do, and really the only thing an avid hiker / paddler / outdoors person is missing from the Apple service that can be a matter of life or death.
