Phoronix: Now that Windows 11 has been out as stable and the initial round of updates coming out, I've been running fresh Windows 11 vs. Linux benchmarks for seeing how Microsoft's latest operating system release compares to the fresh batch of Linux distributions. First up is the fresh look at the Windows 11 vs. Linux performance on an Intel Core i9 11900K Rocket Lake system. Microsoft Windows 11 Pro with all stable updates as of 18 October was used for this round of benchmarking on Intel Rocket Lake. The Windows 11 performance was being compared to all of the latest prominent Linux distributions, including: Ubuntu 20.04.3 LTS, Ubuntu 21.10, Arch Linux (latest rolling), Fedora Workstation 35, Clear Linux 35150. All the testing was done on the same Intel Core i9 11900K test system at stock speeds (any frequency differences reported in the system table come down to how the information is exposed by the OS, i.e. base or turbo reporting) with 2 x 16GB DDR4-3200 memory, 2TB Corsair Force MP600 NVMe solid-state drive, and an AMD Radeon VII graphics card. Each operating system was cleanly installed and then run at its OS default settings for seeing how the out-of-the-box OS performance compares for these five Linux distributions to Microsoft Windows 11 Pro. But for the TLDR version... Out of 44 tests run across all six operating systems, Windows 11 had just three wins on this Core i9 11900K system. Meanwhile Intel's own Clear Linux platform easily dominated with coming in first place 75% of the time followed by Fedora Workstation 35 in second place with first place finishes 9% of the time. The geometric mean for all 44 tests showed Linux clearly in front of Windows 11 for this current-generation Intel platform. Ubuntu / Arch / Fedora were about 11% faster overall than Windows 11 Pro on this system. Meanwhile, Clear Linux was about 18% faster than Windows 11 and enjoyed about 5% better performance overall than the other Linux distributions.

Blue Origin, the rocket and space tourism company founded by Jeff Bezos, is proposing a massive new commercial space station called "Orbital Reef" that could be used to host science experiments, vacation getaways, and potentially even in-space manufacturing. CNN reports: The company plans to work alongside startup Sierra Space to bring the space station to fruition, and Boeing plans to design a research module on the station, though there are no guarantees the companies can make it happen. Such projects are still exorbitantly expensive and risky, likely costing in the tens of billions of dollars and requiring multiple safe launches before a human ever even floats aboard. Blue Origin and Sierra Space plan to co-finance the space station, though executives declined to give an all-in cost estimate during a press conference Monday. They did add that they are expecting to sign on NASA as an anchor tenant, though it's not exactly clear how such a partnership could take shape. Blue Origin hopes Orbital Reef could be operational in the late 2020s, though it will have to get quite a bit done to make that happen. The company has only managed a few crewed suborbital flights so far, much like NASA first achieved back in the early 1960s, and it has yet to put a spacecraft in orbit, let alone a person. A space station would take a major leap. New Glenn, the Blue Origin-built rocket that is expected to be powerful and large enough to haul the biggest portions of the space station to orbit, is not yet operational, and its maiden flight was recently delayed to at least late 2022. The orbital reef will be able to host up to 10 people and will have roughly the same internal volume as the ISS.

An indie developer has found an interesting observation: Though only 5.8% of his game's buyers were playing on Linux, they generated over 38% of the bug reports. Not because the Linux platform was buggier, either. Only 3 of the roughly 400 bug reports submitted by Linux users were platform specific, that is, would only happen on Linux. PC Gamer reports: The developer, posting as Koderski for developer Kodera Software on Reddit, makes indie game [Delta] V: Rings of Saturn -- that's Delta V, or DV, for the non-rocket-science-literate. [...] Koderski says he's sold a little over 12,000 copies of his game, and about 700 of those were bought by Linux players. "I got 1040 bug reports in total, out of which roughly 400 are made by Linux players," says Koderski's post. "That's one report per 11.5 users on average, and one report per 1.75 Linux players. That's right, an average Linux player will get you 650% more bug reports." Koderski's numbers are a limited sample size drawn from one person's experience, but tell a compelling story. Koderski also says that very few of those bugs were specific to Linux, being clear that "This 5.8% of players found 38% of all the bugs that affected everyone." The bug reports themselves were also pretty high quality, he said, including software and OS versions, logs, and steps for replication. Multiple commenters on the post chalked this up to the kind of people who use Linux: Software professionals, IT employees, and engineers who would already be familiar with official bug reporting processes. It's a strong theory as to why this might be, though the sheer passion that the gaming on Linux community has for anyone who supports their favorite hobby may be another.

Time was found to flow differently between the top and bottom of a single cloud of atoms. Physicists hope that such a system will one day help them combine quantum mechanics and Einstein's theory of gravity. From a report: The infamous twin paradox sends the astronaut Alice on a blazing-fast space voyage. When she returns to reunite with her twin, Bob, she finds that he has aged much faster than she has. It's a well-known but perplexing result: Time slows if you're moving fast. Gravity does the same thing. Earth -- or any massive body -- warps space-time in a way that slows time, according to Albert Einstein's general theory of relativity. If Alice lived her life at sea level and Bob at the top of Everest, where Earth's gravitational pull is slightly weaker, he would again age faster. The difference on Earth is modest but real -- it's been measured by putting atomic clocks on mountaintops and valley floors and measuring the difference between the two. Physicists have now managed to measure this difference to the millimeter. In a paper posted earlier this month to the scientific preprint server arxiv.org, researchers from the lab of Jun Ye, a physicist at JILA in Boulder, Colorado, measured the difference in the flow of time between the top and the bottom of a millimeter-tall cloud of atoms. The work is a step toward studying physics at the intersection of general relativity and quantum mechanics, two theories that are famously incompatible. The new clock takes a fundamentally quantum system -- an atomic clock -- and intertwines it with gravity's pull. In the experiment, Ye's team used an optical lattice clock, a cloud of 100,000 strontium atoms that can get tickled by a laser. If the laser's frequency is just right, the electrons orbiting each atom will be excited to a higher, more energetic orbit. Because only a tiny range of laser frequencies motivate the electrons to move, measuring this frequency provides an extremely precise measurement of time. It's like a quantum grandfather clock, where the ticking comes from the oscillations of the laser light rather than the swing of a pendulum.

NASA's Perseverance rover has recorded up to five hours of sounds on the Mars, giving engineers a sense of how the Red Planet sounds different from Earth. Space.com reports: NASA now has a Perseverance rover website filling up with Martian audio, ranging from wind gusts to the sounds of rover driving as it seeks spots to hunt for the signs of life on the Red Planet. In March, we even heard its laser "snapping" (sadly, no pew-pew noise was evident.) "It's like you're really standing there," Baptiste Chide, a planetary scientist who studies data from the Perseverance microphones, said in a statement from NASA's Jet Propulsion Laboratory (JPL). "Martian sounds have strong bass vibrations, so when you put on headphones, you can really feel it. I think microphones will be an important asset to future Mars and solar system science," added Chide, who works at France's Institute of Research in Astrophysics and Planetology. The SuperCam mics have been especially helpful for JPL to learn more about the environment in Jezero Crater, where Perseverance has been roaming for about seven Earth months. In May, Perseverance was able to hear the sound of the Ingenuity drone's rotors buzzing from a distance of 262 feet away. "The audio has been useful for investigations ranging from how sound propagates on Mars, and keeping Perseverance well-maintained," the report adds.

The Chinese military conducted two hypersonic weapons tests over the summer, raising US concerns that Beijing is gaining ground in the race to develop a new generation of arms. Financial Times: On July 27 the Chinese military launched a rocket that used a "fractional orbital bombardment" system to propel a nuclear-capable "hypersonic glide vehicle" around the earth for the first time, according to four people familiar with US intelligence assessments. The Financial Times this week reported that the first test was in August, rather than at the end of July. China subsequently conducted a second hypersonic test on August 13, according to two people familiar with the matter. Three people familiar with the first test in July said it stunned the Pentagon and US intelligence because China managed to demonstrate a brand new weapons capability, although they declined to elaborate on the details. One person said government scientists were struggling to understand the capability, which the US does not currently possess, adding that China's achievement appeared "to defy the laws of physics." Space and missile experts have been debating the Chinese test since the FT revealed the event at the weekend. Jeffrey Lewis, a nuclear weapons expert at Middlebury Institute of International Studies at Monterey, said China appeared to have developed a new innovation, but stressed the need to maintain a degree of scepticism. "We should be open to the reality that China is also capable of technological innovation," he said.

Nanoracks, Voyager Space and Lockheed Martin announced today (Oct. 21) that they plan to get a free-flying private space station up and running in low Earth orbit (LEO) by 2027. Space.com reports: The outpost, called Starlab, is envisioned to be a tourist destination as well as a research and manufacturing hub that helps foster the growth of an off-Earth economy. "To meet U.S. government, international space agency and commercial needs in space, these industry leaders will develop Starlab specifically to enable the growing space economy and meet pent-up customer demand for space services such as materials research, plant growth and astronaut activity," the three companies said in a press release. The four-person Starlab station will be lofted in a single launch, which is expected to take place in 2027. The outpost will feature a habitat module with 12,000 cubic feet (340 cubic meters) of internal volume, a power and propulsion element, a laboratory setup and a large external robotic arm to service payloads and cargo, according to Nanoracks' Starlab page. For comparison, the International Space Station (ISS) has 32,333 cubic feet (916 cubic meters) of internal volume, which is equivalent to that of a Boeing 747 jet.
