"PHP 8.5 landed on Thursday with a long-awaited pipe operator and a new standards-compliant URI parser," reports the Register, "marking one of the scripting language's more substantial updates... " The pipe operator allows function calls to be chained together, which avoids the extraneous variables and nested statements that might otherwise be involved. Pipes tend to make code more readable than other ways to implement serial operations. Anyone familiar with the Unix/Linux command line or programming languages like R, F#, Clojure, or Elixir may have used the pipe operator. In JavaScript, aka ECMAScript, a pipe operator has been proposed, though there are alternatives like method chaining. Another significant addition is the URI extension, which allows developers to parse and modify URIs and URLs based on both the RFC 3986 and the WHATWG URL standards. Parsing with URIs and URLs â" reading them and breaking them down into their different parts â" is a rather common task for web-oriented applications. Yet prior versions of PHP didn't include a standards-compliant parser in the standard library. As noted by software developer Tim Düsterhus, the parse_url() function that dates back to PHP 4 doesn't follow any standard and comes with a warning that it should not be used with untrusted or malformed URLs. Other noteworthy additions to the language include: Clone With, for updating properties more efficiently; the #[\NoDiscard] attribute, for warning when a return value goes unused; the ability to use static closures and first-class callables in constant expressions; and persistent cURL handles that can be shared across multiple PHP requests.

In a 2023 pitch to investors, a "well-financed, highly credentialed" startup named Stardust aimed for a "gradual temperature reduction demonstration" in 2027, according to a massive new 9,600-word article from Politico. ("Annually dispersing ~1 million tons of sun-reflecting particles," says one slide. "Equivalent to ~1% extra cloud coverage.") "Another page told potential investors Stardust had already run low-altitude experiments using 'test particles'," the article notes: [P]ublic records and interviews with more than three dozen scientists, investors, legal experts and others familiar with the company reveal an organization advancing rapidly to the brink of being able to press "go" on its planet-cooling plans. Meanwhile, Stardust is seeking U.S. government contracts and quietly building an influence machine in Washington to lobby lawmakers and officials in the Trump administration on the need for a regulatory framework that it says is necessary to gain public approval for full-scale deployment.... The presentation also included revenue projections and a series of opportunities for venture capitalists to recoup their investments. Stardust planned to sign "government contracts," said a slide with the company's logo next to an American flag, and consider a "potential acquisition" by 2028. By 2030, the deck foresaw a "large-scale demonstration" of Stardust's system. At that point, the company claimed it would already be bringing in $200 million per year from its government contracts and eyeing an initial public offering, if it hadn't been sold already. The article notes that for "a widening circle of researchers and government officials, Stardust's perceived failures to be transparent about its work and technology have triggered a larger conversation about what kind of international governance framework will be needed to regulate a new generation of climate technologies." (Since currently Stardust and its backers "have no legal obligations to adhere to strenuous safety principles or to submit themselves to the public view.") In October Politico spoke to Stardust CEO, Yanai Yedvab, a former nuclear physicist who was once deputy chief scientist at the Israeli Atomic Energy Commission. Stardust "was ready to announce the $60 million it had raised from 13 new investors," the article points out, "far larger than any previous investment in solar geoengineering." [Yedvab] was delighted, he said, not by the money, but what it meant for the project. "We are, like, few years away from having the technology ready to a level that decisions can be taken" - meaning that deployment was still on track to potentially begin on the timeline laid out in the 2023 pitch deck. The money raised was enough to start "outdoor contained experiments" as soon as April, Yedvab said. These would test how their particles performed inside a plane flying at stratospheric heights, some 11 miles above the Earth's surface... The key thing, he insisted, was the particle was "safe." It would not damage the ozone layer and, when the particles fall back to Earth, they could be absorbed back into the biosphere, he said. Though it's impossible to know this is true until the company releases its formula. Yedvab said this round of testing would make Stardust's technology ready to begin a staged process of full-scale, global deployment before the decade is over - as long as the company can secure a government client. To start, they would only try to stabilize global temperatures - in other words fly enough particles into the sky to counteract the steady rise in greenhouse gas levels - which would initially take a fleet of 100 planes. This begs the question: should the world attempt solar geoengineering? That the global temperature would drop is not in question. Britain's Royal Society... said in a report issued in early November that there was little doubt it would be effective. They did not endorse its use, but said that, given the growing interest in this field, there was good reason to be better informed about the side effects... [T]hat doesn't mean it can't have broad benefits when weighed against deleterious climate change, according to Ben Kravitz, a professor of earth and atmospheric sciences at Indiana University who has closely studied the potential effects of solar geoengineering. "There would be some winners and some losers. But in general, some amount of ... stratospheric aerosol injection would likely benefit a whole lot of people, probably most people," he said. Other scientists are far more cautious. The Royal Society report listed a range of potential negative side effects that climate models had displayed, including drought in sub-Saharan Africa. In accompanying documents, it also warned of more intense hurricanes in the North Atlantic and winter droughts in the Mediterranean. But the picture remains partial, meaning there is no way yet to have an informed debate over how useful or not solar geoengineering could be... And then there's the problem of trying to stop. Because an abrupt end to geoengineering, with all the carbon still in the atmosphere, would cause the temperature to soar suddenly upward with unknown, but likely disastrous, effects... Once the technology is deployed, the entire world would be dependent on it for however long it takes to reduce the trillion or more tons of excess carbon dioxide in the atmosphere to a safe level... Stardust claims to have solved many technical and safety challenges, especially related to the environmental impacts of the particle, which they say would not harm nature or people. But researchers say the company's current lack of transparency makes it impossible to trust. Thanks to long-time Slashdot reader fjo3 for sharing the article.

Meta "is testing a new product that would give Facebook users a personalized daily briefing powered by the company's generative AI technology" reports the Washington Post. They cite records they've reviwed showing that Meta "would analyze Facebook content and external sources to push custom updates to its users." The company plans to test the product with a small group of Facebook users in select cities such as New York and San Francisco, according to a person familiar with the project who spoke on the condition of anonymity to discuss private company matters... Meta's foray into pushing updates for consumers follows years of controversy over its relationship with publishers. The tech company has waffled between prominently featuring content from mainstream news sources on Facebook to pulling news links altogether as regulators pushed the tech giant to pay publishers for content on its platforms. More recently, publishers have sued Meta, alleging it infringed on their copyrighted works to train its AI models.

Inter-corporation bullshit screwing over consumers - a tale as old as time. Major laptop vendors have quietly removed hardware decode support for the H.265/HEVC codec in several business and entry-level models, a decision apparently driven by rising licensing fees. Users working with H.265 content may face reduced performance unless they verify codec support or rely on software workarounds. ↫ Hilbert Hagedoornn at The Guru of 3D You may want to know how much these licensing fees are, and by how much they're increasing next year, making these laptop OEMs remove features to avoid the costs. The HEVC licensing fee is $0.20 per device, and in 2026 it's increasing to $0.24. Yes, a $0.04 increase per device is "forcing" these giant companies to screw over their consumers. Nobody's coming out a winner here, and everyone loses. We took a wrong turn, but nobody seems to know when and where.

LisaGUI is an amazing project that recreates the entire user interface of the Apple Lisa in the browser, using nothing but CSS, a bit of HTML, and SVG files, and it's an absolute joy to use and experience. Its creator, Andrew Yaros, has published a blog post diving into the why and how of LisaGUI. I had been trying to think of a good project to add to my programming portfolio, which was lacking. Finding an idea I was willing and able to execute on proved harder than expected. Good ideas are born from necessity and enthusiasm; trying to create a project for its own sake tends to be an uphill battle. I was also hoping to think of a specific project idea that hasn't really been tried before. As you may have guessed by the title of this post, LisaGUI ended up being that project, although I didn't really set out to make it as much as I stumbled into it while trying to accomplish something else. ↫ Andrew Yaros I'm someone who prefers to run the real thing on real hardware, but in a lot of cases, that's just not realistic anymore. Hardware like the Apple Lisa are not only hard to find and expensive, they also require considerable knowledge and skill to maintain and possibly repair, which not everyone can do. For these types of machines, virtualisation, emulation, and recreation are much better, more accessible options, especially if it involves hardware and software you're not interested enough in to spend time and money on them.

After Gandi was bought up and started taking extortion level prices for their domains I've been looking for an excuse to migrate registrar. Last week I decided to bite the bullet and move to Porkbun as I have another domain renewal coming up. However after setting up an account and paying for the transfer for 4 domains, I realized their DNS services are provided by Cloudflare! I personally do not use Cloudflare, and stay far away from all of their products for various reasons.

The waydroid package prior to version 1.5.4-2 (including aur/waydroid) creates Python byte-code files (.pyc) at runtime which were untracked by pacman. This issue has been fixed in 1.5.4-3, where byte-compiling these files is now done during the packaging process. As a result, the upgrade may conflict with the unowned files created in previous versions. If you encounter errors like the following during the update:

error: failed to commit transaction (conflicting files) waydroid: /usr/lib/waydroid/tools/__pycache__/__init__.cpython-313.pyc exists in filesystem waydroid: /usr/lib/waydroid/tools/actions/__pycache__/__init__.cpython-313.pyc exists in filesystem waydroid: /usr/lib/waydroid/tools/actions/__pycache__/app_manager.cpython-313.pyc exists in filesystem

You can safely overwrite these files by running the following command: pacman -Syu --overwrite /usr/lib/waydroid/tools/\*__pycache__/\*

The dovecot 2.4 release branch has made breaking changes which result in it being incompatible with any <= 2.3 configuration file. Thus, the dovecot service will no longer be able to start until the configuration file was migrated, requiring manual intervention. For guidance on the 2.3-to-2.4 migration, please refer to the following upstream documentation: Upgrading Dovecot CE from 2.3 to 2.4 Furthermore, the dovecot 2.4 branch no longer supports their replication feature, it was removed. For users relying on the replication feature or who are unable to perform the 2.4 migration right now, we provide alternative packages available in [extra]:

• dovecot23
• pigeonhole23
• dovecot23-fts-elastic
• dovecot23-fts-xapian

The dovecot 2.3 release branch is going to receive critical security fixes from upstream until stated otherwise.
