Have scientists discovered infrared radiation, evidence of waste heat generated by the energy-harvesting star-surrounding spheres first proposed by British American physicist Freeman Dyson? CNN reports: [A] new study that looked at 5 million stars in the Milky Way galaxy suggests that seven candidates could potentially be hosting Dyson spheres — a finding that's attracting scrutiny and alternate theories... Using historical data from telescopes that pick up infrared signatures, the research team looked at stars located within less than 1,000 light-years from Earth: "We started with a sample of 5 million stars, and we applied filters to try to get rid of as much data contamination as possible," said lead study author Matías Suazo, a doctoral student in the department of physics and astronomy of Uppsala University in Sweden. "So far, we have seven sources that we know are glowing in the infrared but we don't know why, so they stand out...." Among the natural causes that could explain the infrared glow are an unlucky alignment in the observation, with a galaxy in the background overlapping with the star, planetary collisions creating debris, or the fact that the stars may be young and therefore still surrounded by disks of hot debris from which planets would later form... An earlier study, published in March and using data from the same sources as the new report, had also found infrared anomalies among a sample dataset of 5 million stars in our galaxy. "We got 53 candidates for anomalies that cannot be well explained, but can't say that all of them are Dyson sphere candidates, because that's not what we are specifically looking for," said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazo's model to see how many tie into it. "You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere," she added. "To do so you need to also rule out that it's not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy — so it's a win-win." Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASA's James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time. CNN adds that "A May 23 paper published in response to the one by Suazo and his colleagues suggests that at least three of the seven stars have been 'misidentified' as Dyson spheres and could instead be 'hot DOGs' — hot dust-obscured galaxies — and that the remaining four could probably be explained this way as well." But "As for Dyson himself, if he were still alive, he also would be highly skeptical that these observations represent a technological signature, his son George argued: 'But the discovery of new, non-technological astronomical phenomena is exactly why he thought we should go out and look.'

This week the Rust Foundation jointly announced "the Safety-Critical Rust Consortium" with industry partners including Arm, AdaCore, Lynx Software Technologies, and Toyota's mobility tech subsidiary Woven. Its goal is supporting "responsible use" of Rust "in safety-critical software — systems whose failure can impact human life or cause severe environmental or property harm." "This is exciting," said Rust creator Graydon Hoare in a statement. "I am truly pleased to see the Rust Foundation and anyone in the safety-critical space coming together on this topic." From the announcement: "Safety is our foremost priority in vehicle software development. Traditionally, achieving the highest levels of safety has been a complex and lengthy endeavor, requiring the use of specialized tools and processes beyond the programming language," said JF Bastien, Distinguished Engineer at Woven by Toyota. "We are therefore pleased to collaborate with leading experts in the safety industry to integrate new tools such as Rust into our safety-critical systems...." Industries that are particularly concerned with functional safety include transportation (such as automotive, aviation, space), energy, life sciences, and more. Because of their potential impacts, these industries are often regulated, have liability considerations, and are guided by standards... These industries have decades of experience delivering products, learning from iterating based on real-world feedback, and improving processes. An ecosystem of tools and tool vendors have evolved, and best practices have been learned to create a safety culture around tooling. Rust offers particular advantages in terms of developer ergonomics, productivity and software quality; however, it lacks a deep and established well of safety-processes and collective industry knowledge of safety-critical systems. Without closing this gap, a developer must primarily rely on best practices and normative precautions, which can limit innovation. Rust developers who stray from the well-trod path can find themselves facing an inquiry were an accident to occur. In these circumstances, anything that seems unusual will be investigated for fault. This risk creates a disincentive to widespread Rust adoption, leaving developers unable to reap all its advantages while potentially facing financial, reputational and moral costs. The gap in safety-critical resources within the Rust programming language ecosystem is also an exciting opportunity. By rapidly incorporating lessons learned from years of careful development and past mistakes in the wider open source ecosystem, Rust can become a valuable component of a safety toolkit adaptable to various safety-critical industries and severity levels. "Work under the consortium will begin with the creation of a public charter and goals," according to the announcement, with a scope possibly including "the development of guidelines, linters, libraries, static analysis tools, formal methods and language subsets to meet industrial and legal requirements. The group may further shepherd Rust Foundation-funded implementation work, including grants to existing academic teams or FOSS projects... The group will further attempt to coordinate with and expand on existing safety-critical projects and standards including SAE JA1020. The group will maintain communication with the larger Rust Project, and "The Consortium's deliverables will be developed and licensed in a manner compatible with other Rust Project endeavors."

French photovoltaics group Hespul tested solar panels installed in 1992, reports PV Magazine: The testing showed that the modules still produce on average 79.5% of their initial power after 31 years of operation. In a previous testing carried out 11 years ago, the panels were found to produce 91.7% of their initial power. "This result exceeds the performance promised by the manufacturers who said the panels would have maintained 80% of their output after 25 years," said Hespul. The drop in performance is on average 20.5%, or 0.66% per year over 31 years, and 1.11% per year over the last 11 years... Another more recent study carried out by the US Department of Energy's National Renewable Energy Laboratory (NREL) on 1,700 American sites totaling 7.2 GW of power, showed a median degradation of around -0.75%/year. Moveover, another research study focused on 4,300 residential installations in operation in Europe and used different data processing methodologies. Depending on the methods, a median loss of -0.36% to -0.67%/year was obtained. Thanks to long-time Slashdot reader storkus for sharing the news.

An anonymous reader shared this report from Futurism: An AI chatbot named VIC, or Virtually Integrated Citizen, is trying to make it onto the ballot in this year's mayoral election for Wyoming's capital city of Cheyenne. But as reported by Wired, Wyoming's secretary of state is battling against VIC's legitimacy as a candidate — and now, an investigation is underway. According to Wired, VIC, which was built on OpenAI's GPT-4 and trained on thousands of documents gleaned from Cheyenne council meetings, was created by Cheyenne resident and library worker Victor Miller. Should VIC win, Miller told Wired that he'll serve as the bot's "meat puppet," operating the AI but allowing it to make decisions for the capital city.... "My campaign promise," Miller told Wired, "is he's going to do 100 percent of the voting on these big, thick documents that I'm not going to read and that I don't think people in there right now are reading...." Unfortunately for the AI and its — his? — meat puppet, however, they've already made some political enemies, most notably Wyoming Secretary of State Chuck Gray. As Gray, who has challenged the legality of the bot, told Wired in a statement, all mayoral candidates need to meet the requirements of a "qualified elector." This "necessitates being a real person," Gray argues... Per Wired, it's also run amuck with OpenAI, which says the AI violates the company's "policies against political campaigning." (Miller told Wired that he'll move VIC to Meta's open-source Llama 3 model if need be, which seems a bit like VIC will turn into a different candidate entirely.) The Wyoming Tribune Eagle offers more details: [H]is dad helped him design the best system for VIC. Using his $20-a-month ChatGPT subscription, Miller had an 8,000-character limit to feed VIC supporting documents that would make it an effective mayoral candidate... While on the phone with Miller, the Wyoming Tribune Eagle also interviewed VIC itself. When asked whether AI technology is better suited for elected office than humans, VIC said a hybrid solution is the best approach. "As an AI, I bring unique strengths to the role, such as impartial decision-making, data-driven policies and the ability to analyze information rapidly and accurately," VIC said. "However, it's important to recognize the value of human experience and empathy and leadership. So ideally, an AI and human partnership would be the most beneficial for Cheyenne...." The artificial intelligence said this unique approach could pave a new pathway for the integration of human leadership and advanced technology in politics.

Friday the Python Software Foundation published several blog posts about this year's "Python Language Summit" May 15th (before PyCon US), which featured talks and discussions by core developers, triagers, and Python implementation maintainers. There were several lightning talks. One talk came from the maintainer of the PyO3 project, offering Rust bindings for the Python C API (which requires mapping Rust concepts to Python — leaving a question as to how to map Rust's error-handling panic! macro). There was a talk on formalizing the PEP prototype process, and a talk on whether the Python team should have a more official presence in the Apple App Store (and maybe the Google Play Store). One talk suggested changing the formatting of error messages for assert statements, and one covered a "highly experimental" project to support structured data sharing between Python subinterpreters. One talk covered Python's "unsupported build" warning and how it should behave on platforms beyond Python's officially supported list. Python Foundation blog posts also covered some of the longer talks, including one on the idea of using type annotations as a mechanism for transformers. One talk covered the new interactive REPL interpreter coming to Python 3.13. And one talk focused on Python's security model after the xz-utils backdoor: Pablo Galindo Salgado, Steering Council member and the release manager for Python 3.10 and 3.11, brought this topic to the Language Summit to discuss what could be done to improve Python's security model... Pablo noted the similarities shared between CPython and xz-utils, referencing the previous Language Summit's talk on core developer burnout, the number of modules in the standard library that have one or zero maintainers, the high ratio of maintainers to source code, and the use of autotools for configuration. Autotools was used by [xz's] Jia Tan as part of the backdoor, specifically to obscure the changes to tainted release artifacts. Pablo confirmed along with many nods of agreement that indeed, CPython could be vulnerable to a contributor or core developer getting secretly malicious changes merged into the project. For multiple reasons like being able to fix bugs and single-maintainer modules, CPython doesn't require reviewers on the pull requests of core developers. This can lead to "unilateral action", meaning that a change is introduced into CPython without the review of someone besides the author. Other situations like release managers backporting fixes to other branches without review are common. Much discussion ensued about the possibility of altering workflows (including pull request reviews), identity verification, and the importance of post-incident action plans. Guido van Rossum suggested a "higher bar" for granting write access, but in the end "Overall it was clear there is more discussion and work to be done in this rapidly changing area." In another talk, Hugo van Kemenade, the newly announced Release Manager for Python 3.14 and 3.15, "started the Language Summit with a proposal to change Python's versioning scheme. The perception of Python using semantic versioning is a source of confusion for users who don't expect backwards incompatible changes when upgrading to new versions of Python. In reality almost all new feature releases of Python include backwards incompatible changes such as the removal of "dead batteries" where PEP 594 marked 19 modules for removal in Python 3.13. Calendar Versioning (CalVer) encompasses a wide array of different versioning schemes that have one property in common: using the release date as part of a release's version... Hugo offered multiple proposed versioning schemes, including: - Using the release year as minor version (3.YY.micro, "3.26.0") - Using the release year as major version (YY.0.micro, "26.0.0") - Using the release year and month as major and minor version (YY.MM.micro, "26.10.0") [...] Overall the proposal to use the current year as the minor version was well-received, Hugo mentioned that he'd be drafting up a PEP for this change.
