Comment Why does SD remove mod points for a period time? (Score 1) 272
I know not for this Topic.
But I wonder, I still had 10 mod points left. Then SD removes them.
Then they are gone for a few days. Then I get 15 mod points.
Why do they do this?
It does not make me use the mod points. It just makes me mad.
Submission + - Did NASA Just Admit That Boeing's Starliner Is Doomed? (pjmedia.com)
The dock currently occupied by Starliner is needed by a SpaceX Crew Dragon capsule and its four astronauts set to fly the Crew-9 mission. Crew-9 is set for Aug. 18 and is scheduled to arrive at ISS a day or so later. (The exact details are sketchy.) Starliner has to be somewhere else by then, even if Wilmore and Williams aren't aboard it.
Before I get to the real news, understand that every delay in getting another capsule up to ISS has cascading effects down the line and that the station is nearing the end of its service life and will be deorbited in 2030.
This morning I learned that NASA is now considering bumping Crew-9 from Aug. 18 to Sept 24, which space journalist Eric Berger (the best in the business) called "a significant slip." The reason for the possible delay is a virtual confession that Wilmore and Williams will not be coming home on Starliner this week, next week, or ever.
Boeing needs the extra time to prepare Starliner for self-destruct.

Submission + - Hugo Awards Organizers Reveal Thousands Spent On Fraudulent Votes (theguardian.com)
The voting pattern was “startlingly and obviously different” to anything the members of the current Hugo adminstration subcommittee had ever seen, and most of the votes favored one finalist, who the subcommittee called “Finalist A." “We have no evidence that Finalist A was at all aware of the fraudulent votes being cast for them, let alone in any way responsible for the operation. We are therefore not identifying them,” the subcommittee said. Only members of the World Science Fiction Society (WSFS) can nominate works for the Hugos and vote on finalists, which costs a minimum of £45 each year. Based on the Hugo administration subcommittee’s tally, paying for 377 memberships would have cost at least $22,000. The Hugo administration subcommittee said they received “a confidential report that at least one person had sponsored the purchase of WSFS memberships by large numbers of individuals, who were refunded the cost of membership after confirming that they had voted as the sponsor wished."

Nothing against Intel, but I am glad I recently switched and use an AMD Ryzen 9 7950X CPU. It works great for fully modded Skyrim and Baldur's Gate 3. I am glad we now have choices.

Submission + - 500-Year-Old Leonardo Da Vinci Sketches Show Him Grappling With Gravity (gizmodo.com)
Mory Gharib, an engineer at Caltech, said he stumbled across the writings in 2017 when looking for some of da Vinci’s work on flow in hearts. Though the codex was written over a long span of da Vinci’s later years, Gharib suspects the gravitational musings were written sometime in the last 15-or-so years of his life. Gharib recruited co-author Flavio Noca, a researcher at the University of Applied Sciences and Arts Western Switzerland, to translate the Italian’s backward writing on the subject. Da Vinci understood some fundamentals of objects in motion. He wanted to make an experiment testing how the motion of a cloud would correspond to the hail it produced, if the cloud’s velocity and any changes to it corresponded with the falling hail’s velocity. In lieu of control of the weather, da Vinci substituted a pitcher for the cloud and sand or water for the hail. Reliable clocks weren’t available until about 140 years after da Vinci’s death in 1519, the researchers note, so the inventor was forced to substitute the constant of time with space: by assuming that the time it took each water/sand particle to fall from the pitcher was constant, he just kept the pitcher at the same height throughout the tests.
Da Vinci’s sketch shows the positions of the falling material over the course of its trajectory toward the ground. By drawing a line through the position of the material at each instance in time, da Vinci realized that a triangle could be formed, with the drawn line being the hypotenuse. By changing the acceleration of the pitcher over the course of the experiment, one would change the shape of the triangle. Leonardo knew that the falling material would accelerate and that the acceleration is downward. What he wasn’t wholly certain on—hence the experiment—was the relationship between the falling material’s acceleration and the pitcher’s acceleration. In one particular case, when the pitcher’s motion was accelerated to the same rate as the falling material being affected by gravity, an equilateral triangle was formed. Literally, as Da Vinci noted, an “Equatione di Moti” or an “equalization of motions.” The researchers modeled da Vinci’s experiment and found that the polymath was wrong in his understanding of the relationship between the falling object and time. “What we saw is that Leonardo wrestled with this, but he modeled it as the falling object’s distance was proportional to 2 to the t power [with t representing time] instead proportional to t squared,” said Chris Roh, a researcher at Cornell University and a co-author of the researcher, in a Caltech release. “It’s wrong, but we later found out that he used this sort of wrong equation in the correct way.” The team interpreted tick marks on da Vinci’s sketches as data points the polymath made based on his eyeballing of the experiment in action. In lieu of a timepiece, da Vinci found the gravitational constant to nearly 98% accuracy.
Submission + - Super-massive Black hole ejected from galaxy. (arxiv.org) 1
As part of a study of "low-surface-brightness galaxies" using the Hubble Space Telescope, this 16-strong team noticed a long, linear feature in one of their images. Initially thinking it was a cosmic ray, they looked at the second image taken of the region on HST's next orbit (and through a different filter) — and found it was still visible. In the immortal words of real world science "that's odd", so they investigated more closely.
Their best model of the data is that their target galaxy "RCP 28" merged with another galaxy about 39 million years ago (from our point of view), leading to the ejection of one, or possibly two central black holes from the original galaxies. That would require one of the galaxies to have been the result of a previous merger, but whose central black holes had not yet merged (an event we might have detected using our shiny new gravitational wave telescopes, had they been 39.1 million years ahead of their construction schedules).
After the collision and ejection from the galaxy core, the passage of the black hole through the galaxy and it's surrounding material produced a burst of star formation along that line, which we now see as a faint linear streak of light.
The HST images may show a much fainter streak in the opposite direction, hinting at a second ejected black hole. Or it might be noise. Or something else.
Those who like doom-laden prophecies will be upset to hear that, because we can see this moving across the plane of the sky, it is never going to come any where near us. Even if it weren't moving across our line of sight, at a redshift of z=0.964 (equivalent to about 1600 MPc, I think) it's a toss up which hits us first — this black hole, or the expanding surface of the red giant Sun.

I know what you mean about memorizing opening moves. I use to play chess in highschool and was pretty good. Then went to a tournament and got destroyed when someone played the sicilian defense against me. Lost in around 10 moves. I then knew I had to memorize opening moves if I wanted to move up in the rankings, but had no interest. So eventually gave up on playing chess. Still like the game, but rarely if ever play now.
IBM and Maersk Abandon Ship on TradeLens Logistics Blockchain (coindesk.com) 28
The idea was to save its member-shipping companies money by connecting their world. But the network was only as strong as its participants; despite some early wins, TradeLens ultimately failed to catch on with a critical mass of its target industry. "TradeLens has not reached the level of commercial viability necessary to continue work and meet the financial expectations as an independent business," Maersk Head of Business Platforms Rotem Hershko said in a statement.
