From the network-effects department: The blog Its FOSS has 15,000 followers for its Mastodon account — which they think is causing problems:
When you share a link on Mastodon, a link preview is generated for it, right? With Mastodon being a federated platform (a part of the Fediverse), the request to generate a link preview is not generated by just one Mastodon instance. There are many instances connected to it who also initiate requests for the content almost immediately. And, this "fediverse effect" increases the load on the website's server in a big way.
Sure, some websites may not get overwhelmed with the requests, but Mastodon does generate numerous hits, increasing the load on the server. Especially, if the link reaches a profile with more followers (and a broader network of instances)... We tried it on our Mastodon profile, and every time we shared a link, we were able to successfully make our website unresponsive or slow to load.
Slashdot reader nunojsilva is skeptical that "blurbs with a thumbnail and description" could create the issue (rather than, say, poorly-optimized web content). But the It's Foss blog says they found three GitHub issues about the same problem — one from 2017, and two more from 2023. And other blogs also reported the same issue over a year ago — including software developer Michael Nordmeyer and legendary Netscape programmer Jamie Zawinski.
And back in 2022, security engineer Chris Partridge wrote:
[A] single roughly ~3KB POST to Mastodon caused servers to pull a bit of HTML and... an image. In total, 114.7 MB of data was requested from my site in just under five minutes — making for a traffic amplification of 36704:1. [Not counting the image.]
Its Foss reports Mastodon's official position that the issue has been "moved as a milestone for a future 4.4.0 release. As things stand now, the 4.4.0 release could take a year or more (who knows?)."

From the very-old-news department: An anonymous reader shared this report from the Guardian:
Newly deciphered passages from a papyrus scroll that was buried beneath layers of volcanic ash after the AD79 eruption of Mount Vesuvius may have shed light on the final hours of Plato, a key figure in the history of western philosophy. In a groundbreaking discovery, the ancient scroll was found to contain a previously unknown narrative detailing how the Greek philosopher spent his last evening, describing how he listened to music played on a flute by a Thracian slave girl. Despite battling a fever and being on the brink of death, Plato — who was known as a disciple of Socrates and a mentor to Aristotle, and who died in Athens around 348BC — retained enough lucidity to critique the musician for her lack of rhythm, the account suggests....
In a presentation of the research findings at the National Library of Naples, Prof Graziano Ranocchia, of the University of Pisa, who spearheaded the team responsible for unearthing the carbonised scroll, described the discovery as an "extraordinary outcome that enriches our understanding of ancient history". He said: "Thanks to the most advanced imaging diagnostic techniques, we are finally able to read and decipher new sections of texts that previously seemed inaccessible... For the first time, we have been able to read sequences of hidden letters from the papyri that were enfolded within multiple layers, stuck to each other over the centuries, through an unrolling process using a mechanical technique that disrupted whole fragments of text."

From the having-good-chemistry department: "A leap in our ability to see the chemistry of matter in three-dimensions at the nanoscale was achieved, allowing scientists to understand how nanomaterials are chemically arranged," writes Slashdot reader Hovden:
Traditionally, seeing matter at the smallest sizes requires too many high-energy electrons for 3D chemical imaging. The high beam exposure destroys the specimen before an experiment is completed. Even larger doses are required to achieve high resolution.
Thus, chemical mapping in 3D has been unachievable except at lower resolution with the most radiation-hard materials.
High-resolution 3D chemical imaging is now achievable near or below one-nanometer resolution. A team from Dow Chemical and the University of Michigan used a newly introduced method, called multi-modal data fusion, high-resolution chemical tomography, that provides 99% less dose by linking information encoded within both elastic and inelastic scattered signals. The researchers showed sub-nanometer 3D resolution of chemistry is measurable for a broad class of geometrically and compositionally complex materials.
"Here are the pretty pictures," adds long-time Slashdot reader thoper.
Phys.org also has this quote from Robert Hovden, an associate professor of materials science and engineering at the University of Michigan and corresponding author on the study published in Nature Communications. "Seeing invisible worlds, far smaller than the wavelengths of light, is absolutely critical to understanding the matter we are engineering at the nanoscale, not just in 2D but in 3D as well."

From the Redmond-reports department: Thursday the Verge reported that a new report from Microsoft "outlines the steps the company took to release responsible AI platforms last year."
Microsoft says in the report that it created 30 responsible AI tools in the past year, grew its responsible AI team, and required teams making generative AI applications to measure and map risks throughout the development cycle. The company notes that it added Content Credentials to its image generation platforms, which puts a watermark on a photo, tagging it as made by an AI model.
The company says it's given Azure AI customers access to tools that detect problematic content like hate speech, sexual content, and self-harm, as well as tools to evaluate security risks. This includes new jailbreak detection methods, which were expanded in March this year to include indirect prompt injections where the malicious instructions are part of data ingested by the AI model.
It's also expanding its red-teaming efforts, including both in-house red teams that deliberately try to bypass safety features in its AI models as well as red-teaming applications to allow third-party testing before releasing new models.
Microsoft's chief Responsible AI officer told the Washington Post this week that "We work with our engineering teams from the earliest stages of conceiving of new features that they are building."
"The first step in our processes is to do an impact assessment, where we're asking the team to think deeply about the benefits and the potential harms of the system. And that sets them on a course to appropriately measure and manage those risks downstream. And the process by which we review the systems has checkpoints along the way as the teams are moving through different stages of their release cycles...

From the gimme-a-brake department: Come 2029, all cars sold in the U.S. "must be able to stop and avoid contact with a vehicle in front of them at speeds up to 62 mph," reports Car and Driver.
"Additionally, the system must be able to detect pedestrians in both daylight and darkness. As a final parameter, the federal standard will require the system to apply the brakes automatically up to 90 mph when a collision is imminent, and up to 45 mph when a pedestrian is detected."
Notably, the federal standardization of automated emergency braking systems includes pedestrian-identifying emergency braking, too. Once implemented, the NHTSA projects that this standard will save at least 360 lives a year and prevent at least 24,000 injuries annually. Specifically, the federal agency claims that rear-end collisions and pedestrian injuries will both go down significantly...
"Automatic emergency braking is proven to save lives and reduce serious injuries from frontal crashes, and this technology is now mature enough to require it in all new cars and light trucks. In fact, this technology is now so advanced that we're requiring these systems to be even more effective at higher speeds and to detect pedestrians," said NHTSA deputy administrator Sophie Shulman.

From the neigh-sayers department: In 2016, an online "swarm intelligence" platform generated a correct prediction for the Kentucky Derby — naming all four top finishers, in order. (But the next year their predictions weren't even close, with TechRepublic suggesting 2016's race had an unusual cluster of just a few top racehorses.)
So this year Decrypt.co tried crafting their own system "that can be called up when the next Kentucky Derby draws near.
There are a variety of ways to enlist artificial intelligence in horse racing. You could process reams of data based on your own methodology, trust a third-party pre-trained model, or even build a bespoke solution from the ground up. We decided to build a GPT we named HorseGPT to crunch the numbers and make the picks for us...
We carefully curated prompts to instill HorseGPT with expertise in data science specific to horse racing: how weather affects times, the role of jockeys and riding styles, the importance of post positions, and so on. We then fed it a mix of research papers and blogs covering the theoretical aspects of wagering, and layered on practical knowledge: how to read racing forms, what the statistics mean, which factors are most predictive, expert betting strategies, and more. Finally, we gave HorseGPT a wealth of historical Kentucky Derby data, arming it with the raw information needed to put its freshly imparted skills to use.
We unleashed HorseGPT on official racing forms for this year's Derby. We asked HorseGPT to carefully analyze each race's form, identify the top contenders, and recommend wager types and strategies based on deep background knowledge derived from race statistics.

From the it's-a-Snap department: The blog It's FOSS is "pissed at the casual arrogance of Ubuntu and its parent company Canonical..... The sheer audacity of not caring for its users reeks of Microsoft-esque arrogance."
If you download a .deb package of a software, you cannot install it using the official graphical software center on Ubuntu anymore. When you double-click on the downloaded deb package, you'll see this error, "there is no app installed for Debian package files".
If you right-click and choose to open it with Software Center, you are in for another annoyance. The software center will go into eternal loading. It may look as if it is doing something, but it will go on forever. I could even livestream the loading app store on YouTube, and it would continue for the 12 years of its long-term support period.
Canonical software engineer Dennis Loose actually created an issue ticket for the problem himself — back in September of 2023. And two weeks ago he returned to the discussion to announce that fix "will be a priority for the next cycle". (Though "unfortunately we didn't have the capacity to work on this for 24.04...)
But Its Foss accused Canonical of "cleverly booting out deb in favor of Snap, one baby step at a time" (noting the problem started with Ubuntu 23.10):
There is also the issue of replacing deb packages with Snap, even with the apt command line tool. You use 'sudo apt install chromium', you get a Snap package of Chromium instead of Debian
The venerable Linux magazine argues that Canonical "has secretly forced Snap installation on users."
[I]t looks as if the Software app defaults to Snap packages for everything now. I combed through various apps and found this to be the case.... As far as the auto-installation of downloaded .deb files, you'll have to install something like gdebi to bring back this feature.

From the this-is-only-a-test department: An anonymous reader shared this report from the Washington Post:
The heat shield of the Orion spacecraft intended one day to carry astronauts to the moon under NASA's Artemis program suffered unexpected damage in more than 100 places as the spacecraft returned to Earth during an uncrewed test flight in 2022, according to a watchdog report released late Wednesday.
While the capsule withstood the fiery tumult of reentry, when temperatures reached 5,000 degrees Fahrenheit as it plunged through the atmosphere at nearly 25,000 mph, the damage the heat shield suffered was far greater than NASA engineers had expected and more severe than NASA had revealed previously. Photos of the heat shield in the report showed gouges that look like small potholes. "Should the same issue occur on future Artemis missions, it could lead to the loss of the vehicle or crew," the report, by NASA's inspector general, concluded...
The IG report provides the most detailed description of the issue to date. It also highlighted other problems with the spacecraft that could create significant challenges for the space agency as it seeks to return humans to the lunar surface for the first time in more than 50 years.
Portions of the heat shield "wore away differently than NASA engineers predicted, cracking and breaking off the spacecraft in fragments that created a trail of debris rather than melting away as designed," according to the report. That, in turn, "could have caused enough structural damage to cause one of Orion's parachutes to fail...." In addition to the heat shield erosion on Orion, which is manufactured by Lockheed Martin, the IG said several bolts on the crew module "experienced an exposed gap that allowed for increased heating to the bolt interior and greater than expected melting and erosion."

From the power-plays department: The Washington Post reports that wind turbines "only take up five percent of the land where they've been built, new research shows."
The rest of the space can be used for other purposes, such as agriculture, according to a study published recently in the peer-reviewed journal Environmental Science and Technology. This means developers could fit turbines in places that are often perceived as unsuitable for a wind farm.
The new study highlights that turbines and existing human development, such as agriculture, cannot only share the same area, but also that building wind farms where there are already roads and other infrastructure could help reduce impacts on the land. "Clever siting, use of existing infrastructure, multiple use of landscapes — all these things ... can really contribute to solutions in areas where wind power is acceptable to the local people," said Sarah Jordaan, the study's principal investigator.
Historically, planning studies for wind farms have often assumed that turbines would disturb all the land at the site and leave the area unusable for anything else, said Jordaan, an associate professor in the department of civil engineering at McGill University. The study's findings provide a more accurate accounting of how much land is needed for wind farms, she added.

From the Block-unchained department: An anonymous reader shared this report from the blog Bitcoinist:
Jack Dorsey's financial services and digital payments company, Block Inc., announced it will begin investing 10% of its monthly Bitcoin-related gross profits into BTC purchases. This announcement was made following the release of Block's first-quarter earnings for 2024, which demonstrated substantial profits from its Bitcoin operations.
Block reported Bitcoin-related gross profits amounting to $80 million in the first quarter alone. If this trend continues, the implementation of the new dollar cost averaging (DCA) program could see the company investing approximately $24 million in Bitcoin within one year... Dorsey also shared a detailed document [PDF] titled "Bitcoin Blueprint For Corporate Balance Sheets," which serves as a comprehensive guide for other corporations interested in integrating BTC into their financial strategies.
According to the document, Block, formerly known as Square, began its substantial acquisitions in October 2020, purchasing 4,709 BTC at an aggregate price of $50 million. The company later bought an additional 3,318 BTC in February 2021 for $170 million. As of March 31, 2024, Block holds approximately 8,038 BTC, representing about 9% of its total cash and marketable securities.
