Comment On the one hand, on the other hand ... (Score 2) 43

On the one hand, H-1B and other immigrant worker programs can be horribly abused, mostly by contractors ("body shops"), sometimes by companies directly hiring. The abuse comes in the form of both mistreatment of immigrant workers, and negative salary pressure and/or lost employment opportunities for citizens and green card holders.

On the other hand, H-1B is completely broken for Indians, and seems excessively permissive for mainland Chinese. I've had H-1B coworkers who were complete crap and others who I count as not only excellent coworkers but good friends. The good ones shouldn't be under constant threat of being forced to leave the country on a few weeks notice.

But I don't think this is what this is all about. I don't think H-1B immigrants are anyone's favorite right now.

My final thought is that we have historically low unemployment, and we just plain need more workers. We also work existing employees too many hours. This is no longer 1940 where the 40 hour work week was standardized. We're just doing it wrong in both little and big ways and no one seems to want to sort it out.

Submission + - Brazilian Frog Might Be the First Pollinating Amphibian Known To Science (science.org)

An anonymous reader writes: The creamy fruit and nectar-rich flowers of the milk fruit tree are irresistible to Xenohyla truncata, a tree frog native to Brazil. On warm nights, the dusky-colored frogs take to the trees en masse, jostling one another for a chance to nibble the fruit and slurp the nectar. In the process, the frogs become covered in sticky pollen grains—and might inadvertently pollinate the plants, too. It’s the first time a frog—or any amphibian—has been observed pollinating a plant, researchers reported last month in Food Webs.

Scientists long thought only insects and birds served as pollinators, but research has revealed that some reptiles and mammals are more than up to the task. Now, scientists must consider whether amphibians are also capable of getting the job done. It’s likely that the nectar-loving frogs, also known as Izecksohn’s Brazilian tree frogs, are transferring pollen as they move from flower to flower, the authors say. But more research is needed, they add, to confirm that frogs have joined the planet’s pantheon of pollinators.

Comment Re: There are few photos of Concorde at altitude (Score 1) 51

I can't say as I've seen a lot of formation flying involving commercial transport aircraft even when subsonic.

The cost of flying Concorde was in the neighborhood of $50,000-100,000/hr (2022 dollars) so that would be a pricey photograph - I doubt the aircraft would be allowed to fly in proximity while carrying passengers so basically both aircraft would have to be ferry/deadhead.

There are some problems with supersonic flight that will prevent it from being ordinary, but there is certainly a market for it.

* Fuel economy - probably decent at cruise but not in other regimes
* Sonic boom - the hope is that decades of research have created designs with drastically reduced sonic boom
* Emissions into the stratosphere - a drastic expansion of air travel into the stratosphere would probably not be allowed by environmental regulators

But there are plenty of filthy rich people in the world these days who won't mind shelling out $10,000 or more every time they get in an airplane.

Comment However, those 1960s Mach 2 fighters ... (Score 1) 51

... couldn't do "supercruise" as in supersonic flight without "reheat" (afterburner). Thus they were restricted to single digit minutes of supersonic flight rather than an entire ocean of it.

Concorde was a pretty cool engineering trick. Like the SR-71 it was a pig on the ground, but unmatched at altitude.

It turns out that an airplane that can fly at Mach 1.5+ at 50-60,000 feet is actually tremendously difficult to photograph at altitude, because essentially no existing military aircraft can chase it.

Concorde at Mach 2 and 60,000 feet couldn't be chased. You could shoot it down, but that's much easier.

Few fighters designed in the past 20-30 years are even capable of Mach 2, as high top speed is no longer a priority. On the other hand, scads of fighters designed in the 1960s and early 70s could (and still can) fly at >Mach 2.

Comment AWS us-east-1 (IAD) (Score 0) 42

IAD is roughly twice as large as the next largest AWS region in the world (us-west-2, PDX) and as someone who knows, I recommend you use a different zone (us-east-2, CMH is pretty solid), to avoid unique scaling problems. IAD is an exception to the limits in essentially every service that operates there.

But if you need a few hundred i{3,4}.16xl, or whatever, that's probably where you're gonna land. Good luck!

Comment Re:Multiple pictures / video as input (Score 1) 48

So, many cellphone camera tricks these days use numerous exposures, as from the camera shooting video instead of stills.

"Night Sight" for example.

As far as gathering the photographs needed goes, moving a cellphone camera around is all that's needed. The compute resources, might be a while before those go into the phone itself.
