The volume of solar electricity generated and proportion of self-consumption at the Lake Maiwald floating plant have both surpassed expectations. Gravel company Ossola has been able to reduce its electricity bill 10% as a result.

The information security (infosec) community has angrily reacted today to calls to abandon the use of the 'black hat' and 'white hat' terms, citing that the two, and especially 'black hat,' have nothing to do with racial stereotyping.
Discussions about the topic started late last night after David Kleidermacher, VP of Engineering at Google, and in charge of Android Security and the Google Play Store, withdrew from a scheduled talk he was set to give in August at the Black Hat USA 2020 security conference.
In his withdrawal announcement, Kleidermacher asked the infosec industry to consider replacing terms like black hat, white hat, and man-in-the-middle with neutral alternatives.
These changes remove harmful associations, promote inclusion, and help us break down walls of unconscious bias. Not everyone agrees which terms to change, but I feel strongly our language needs to (this one in particular).

While Kleidermacher only asked the industry to consider changing these terms, several members mistook his statement as a direct request to the Black Hat conference to change its name.
With Black Hat being the biggest event in cyber-security, online discussions on the topic quickly became widespread among cyber-security experts, dominating the July 4th weekend.
While a part of the infosec community agreed with Kledermacher, the vast majority did not, and called it virtue signaling taken to the extreme.
Most security researchers pointed to the fact that the terms had nothing to do with racism or skin color, and had their origins in classic western movies, where the villain usually wore a black hat, while the good guy wore a white hat.
Others pointed to the dualism between black and white as representing evil and good, concepts that have been around since the dawn of civilizations, long before racial divides even existed between humans.
Right now, the infosec community doesn't seem to be willing to abandon the two terms, which they don't see as a problem when used in infosec-related writings.
One day toward the end of the Jurassic Period, a long-necked, long-tailed sauropod dinosaur about the size of an elephant lumbered over a tidal flat in what is now Switzerland, leaving footprints wider than beach balls.#Science #Research #Fossils #Palaeontology #Sauropods #Turtles #Dinosaurs #Reptiles
Maybe it heard a crunch. Because much later, near these footprints, a team of paleontologists found a damaged carapace from an extinct sea turtle species called Plesiochelys bigleri halfway pressed into the sediment. They argue, in a paper soon to be published in the Swiss Journal of Geosciences, that animal was stepped on.
“The evidence is pretty clear,” said Daniel Marty, a paleontologist at the Natural History Museum in Basel, Switzerland, who participated in the study. “It’s kind of a funny thing, and it also shows that these two animals were in the same paleoenvironment.”
Another explanation, said Jordan Mallon, a paleontologist at the Canadian Museum of Nature who also was not involved in the study, is that the fossil was simply crushed under the weight of the rocks above it over the millions of years it was buried. “I think they tell a plausible story, but it’s not a dead ringer,” he said.
Still, “it’s important to document fossils like this where you can try and show two species lived together,” Dr. Mallon said. “It’s only by doing that that we’re able to reconstruct ancient ecosystems.”"
Only five people in the world get to routinely handle these precious pebbles, sample processor Charis Krysher tells me. She’s one of them. But even Krysher and the lucky few can’t touch the samples directly. To pick up an Apollo rock, Krysher must either use stainless steel tweezers or slide her fingers into a third set of gloves made of Teflon.#Space #Moon #Geology #Rocks #MoonRocks #Research
All this effort is to protect the 382 kilograms of rocks, core samples, pebbles, sand and dust lifted from the moon during the six Apollo landings from 1969 through 1972. Those priceless samples are still offering fresh details about how the moon — and the entire solar system — formed and evolved. The rocks have revealed the rough ages of all the rocky planets’ surfaces and informed debate about whether an ancient reshuffling of the outer planets caused a bombardment of meteorites on Earth (SN Online: 9/12/16).
Since those first bits of moon arrived, NASA has sent about 50,000 individual samples to 500 research labs in more than 15 countries. Even with all that sharing, upward of 80 percent of the original haul is still untouched. Keeping with NASA’s hypercareful approach, nearly 15 percent of that lot is stored in a vault at the White Sands Test Facility near Las Cruces, N.M., a roughly 1,300-kilometer drive from Houston.
Designers also constructed this boxy, beige building in Houston, which opened in 1979, with certain disasters in mind. The structure is hurricane-resistant, and the pristine sample lab is one story above ground level to avoid flooding."
A dollop of Nutella and slices of banana make for the perfect crêpe filling, at least according to Mathieu Sellier of the University of Canterbury in New Zealand. Edouard Boujo, who works at the École Polytechnique in France, smothers his in chocolate, nothing else. While the two disagree on what should coat these batter-based desserts, they concur that the crêpe itself should have a uniform thickness. Challenged by Sellier’s wife to use their physics expertise to suggest the optimal way to cook a crêpe, the duo finds that it requires inclining the frying pan and rotating it in circles.#Science #Research #Food
Conventional wisdom holds that earthworms head to the surface after rain because they can’t breathe. This is still taught to schoolkids, and you can find a lot of detailed explanation online. Most claim that worm trails and air pockets underground become submerged, and the earthworms can’t breathe. It makes sense.#Science #Research #Biology #Earthworms #Invertebrates
Most researchers, though, dispute this explanation. As Chris Lowe, a researcher at the University of Central Lancashire, points out in Scientific American, earthworms breathe through their skin and require moisture to do so.
Humans drown when their lungs fill with water. This is not possible for earthworms as they lack lungs. Multiple studies have also shown that most earthworm species can survive being submerged in water for two weeks or more.
Lately, most popular scientific accounts write off the “drowning worm” idea as a myth. While it is certainly not likely the entire explanation, perhaps we shouldn’t entirely rule it out. Research published in the journal Invertebrate Biology, for instance, found that worm behavior following rain depended on the species.
There undoubtedly will be new research and new revelations about the lives and habits of earthworms. Nature’s mysteries are not just “out there” in the wilderness. The common creatures that live around us still hold surprises. Take a moment and observe the phenomenon happening in the natural world, right now, where we live. The surprises and wonders are right under our feet."
"[...] scientists often find that they can't publish their interesting (if somewhat ambiguous) results if they aren't statistically significant. But that information is actually still useful, and advocates say it's wasteful simply to throw it away."For a deeper look at it: https://www.nature.com/articles/d41586-019-00857-9
"The advocates for change say the community can still use the p-value test, but as part of a broader approach to measuring uncertainty."
"Uncertainty is present always," Wasserstein says. "That's part of #science. So rather than trying to dance around it, we [should]accept it."
