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.

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?)."

They also state their opinion that the issue "should have been prioritized for a faster fix... Don't you think as a community-powered, open-source project, it should be possible to attend to a long-standing bug, as serious as this one?"

HN Discussion

Canadian legislators proposed 19,600 amendments—almost certainly AI-generated—to a bill in an attempt to delay its adoption.

Meanwhile, in Southern California, nonprofit news site Canary Media reports that an old gas combustion plant is being replaced by a "power bank" named Nova.

It's expected to store "more electricity than all but one battery plant currently operating in the U.S."

The billion-dollar project, with 680 megawatts and 2,720 megawatt-hours, will help California shift its nation-leading solar generation into the critical evening and nighttime hours, bolstering the grid against the heat waves that have pushed it to the brink multiple times in recent years... The town of Menifee gets to move on from the power plant exhaust that used to join the smog flowing from Los Angeles... And the grid gets a bunch more clean capacity that can, ideally, displace fossil fuels...

Moreover, [the power bank] represents Calpine's grand arrival in the energy storage market, after years operating one of the biggest independent gas power plant fleets in the country alongside Vistra and NRG... Federal analysts predict 2024 will be the biggest-ever year for grid battery installations across the U.S., and they highlighted Calpine's project as one of the single largest projects. The 620 megawatts the company plans to energize this year represent more than 4% of the industry's total expected new additions.

Many of these new grid batteries will be built in California, which needs all the dispatchable power it can get to meet demand when its massive solar fleet stops producing, and to keep pace with the electrification of vehicles and buildings. The Menifee Power Bank, and the other gigawatts worth of storage expected to come online in the state this year, will deliver much-needed reinforcement.

The company says it's planning "a portfolio" of 2,000 megawatts of California battery capacity.

But even this 680-megawatt project consists of 1,096 total battery containers holding 26,304 battery modules (or a total of 3 million cells), "all manufactured by Chinese battery powerhouse BYD, according to Robert Stuart, an electrical project manager with Calpine. That's enough electricity to supply 680,000 homes for four hours before it runs out."

What's remarkable is just how quickly the project came together. Construction began last August, and is expected to hit 510 megawatts of fully operational capacity over the course of this summer, even as installation continues on other parts of the plant. Erecting a conventional gas plant of comparable scale would have taken three or four years of construction labor, due to the complexity of the systems and the many different trades required for it, Stuart told Canary Media... That speed and flexibility makes batteries a crucial solution as utilities across the nation grapple with a spike in expected electricity demand unlike anything seen in the last few decades.

The article notes a 2013 Caifornia policy mandating battery storage for its utility companies, which "kicked off a decade-long project to will an energy storage market into existence through methodical policies and regulations, and the knock-on effects of building the nation's foremost solar fleet."

Those energy storage policies succeeded in jumpstarting the modern grid battery market: California leads the nation with more than 7 gigawatts of batteries installed as of last year (though Texas is poised to overtake California in battery installations this year, on the back of no particular policy effort but a general openness to building energy projects)... California's interlocking climate regulations effectively rule out new gas construction. The state's energy roadmap instead calls for massive expansion of battery capacity to shift the ample amounts of solar generation into the evening peaks.

"These trends, along with the falling price of batteries and maturing business model for storage, nudged Calpine to get into the battery business, too."

Hello, I noticed some of my early posts (less than a year ago) disappeared. I did not receive notification about the removal. Hence I suppose it could be due to one of those:

• the instance hosting the community got defederated
• the community I posted in was removed
• there is some automatic cleanup job of old posts on Lemmy.ml

This is not mentioned in Lemmy.ml's presentation section. Does this instance implement pruning? (if so; what is the retention duration?) Is it possible to check the retention policy of a Lemmy instance?

"Researchers have successfully transformed CO2 into methanol," reports SciTechDaily, "by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels."

Tara LeMercier, a PhD student who carried out the experimental work at the University of Nottingham, School of Chemistry, said: "We measured the current generated by light and used it as a criterion to judge the quality of the catalyst. Even without copper, the new form of carbon nitride is 44 times more active than traditional carbon nitride. However, to our surprise, the addition of only 1 mg of copper per 1 g of carbon nitride quadrupled this efficiency. Most importantly the selectivity changed from methane, another greenhouse gas, to methanol, a valuable green fuel."

Professor Andrei Khlobystov, School of Chemistry, University of Nottingham, said: "Carbon dioxide valorization holds the key for achieving the net-zero ambition of the UK. It is vitally important to ensure the sustainability of our catalyst materials for this important reaction. A big advantage of the new catalyst is that it consists of sustainable elements — carbon, nitrogen, and copper — all highly abundant on our planet." This invention represents a significant step towards a deep understanding of photocatalytic materials in CO2 conversion. It opens a pathway for creating highly selective and tuneable catalysts where the desired product could be dialed up by controlling the catalyst at the nanoscale.

Two years into office, President Donald Trump authorized the Central Intelligence Agency to launch a clandestine campaign on Chinese social media aimed at turning public opinion in China against its government, according to former U.S. officials with direct knowledge of the highly classified operation. Three former officials told Reuters that the CIA created a small team of operatives who used bogus internet identities to spread negative narratives about Xi Jinping's government while leaking disparaging intelligence to overseas news outlets. The effort, which began in 2019, has not been previously reported.

The CIA team promoted allegations that members of the ruling Communist Party were hiding ill-gotten money overseas and slammed as corrupt and wasteful China's Belt and Road Initiative, which provides financing for infrastructure projects in the developing world, the sources told Reuters. Although the U.S. officials declined to provide specific details of these operations, they said the disparaging narratives were based in fact despite being secretly released by intelligence operatives under false cover. The efforts within China were intended to foment paranoia among top leaders there, forcing its government to expend resources chasing intrusions into Beijing's tightly controlled internet, two former officials said. "We wanted them chasing ghosts," one of these former officials said. [...]

The CIA operation came in response to years of aggressive covert efforts by China aimed at increasing its global influence, the sources said. During his presidency, Trump pushed a tougher response to China than had his predecessors. The CIA's campaign signaled a return to methods that marked Washington's struggle with the former Soviet Union. "The Cold War is back," said Tim Weiner, author of a book on the history of political warfare. Reuters was unable to determine the impact of the secret operations or whether the administration of President Joe Biden has maintained the CIA program.

The Guardian can reveal Transport for London (TfL) has been accused by five EU countries of illegally obtaining the names and addresses of their citizens in order to issue the fines, with more than 320,000 penalties, some totalling thousands of euros, sent out since 2021...

Since Brexit, the UK has been banned from automatic access to personal details of EU residents. Transport authorities in Belgium, Spain, Germany and the Netherlands have confirmed to the Guardian that driver data cannot be shared with the UK for enforcement of London's ultra-low emission zone (Ulez), and claim registered keeper details were obtained illegally by agents acting for TfL's contractor Euro Parking Collection. In France, more than 100 drivers have launched a lawsuit claiming their details were obtained fraudulently, while Dutch lorry drivers are taking legal action against TfL over £6.5m of fines they claim were issued unlawfully.

According to the Belgian MP Michael Freilich, who has investigated the issue on behalf of his constituents, TfL is treating European drivers as a "cash cow" by using data obtained illegitimately to issue unjustifiable fines.

Freilich describes the situation as "possibly one of the largest privacy and data breaches in EU history," according to the article.

Some drivers have even received penalties of up to five-figure sums — for compliant vehicles which had simply not yet been registered. And "some low-emission cars have been misclassed as heavy goods diesel vehicles and fined under the separate low-emission zone scheme, which incurs penalties of up to £2,000 a day."

Seagate this week unveiled the industry's first hard disk drive platform that uses heat-assisted media recording (HAMR). Tom's Hardware:

The new Mozaic 3+ platform relies on several all-new technologies, including new media, new write and read heads, and a brand-new controller. The platform will be used for Seagate's upcoming Exos hard drives for cloud datacenters with a 30TB capacity and higher. Heat-assisted magnetic recording is meant to radically increase areal recording density of magnetic media by making writes while the recording region is briefly heated to a point where its magnetic coercivity drops significantly.

Seagate's Mozaic 3+ uses 10 glass disks with a magnetic layer consisting of an iron-platinum superlattice structure that ensures both longevity and smaller media grain size compared to typical HDD platters. To record the media, the platform uses a plasmonic writer sub-system with a vertically integrated nanophotonic laser that heats the media before writing. Because individual grains are so small with the new media, their individual magnetic signatures are lower, whereas magnetic inter-track interference (ITI) effect is somewhat higher. As a result, Seagate had to introduce its new Gen 7 Spintronic Reader, which features the "world's smallest and most sensitive magnetic field reading sensors," according to the company. Because Seagate's new Mozaic 3+ platform deals with new media with a very small grain size, an all-new writer, and a reader that features multiple tiny magnetic field readers, it also requires a lot of compute horsepower to orchestrate the drive's work. Therefore, Seagate has equipped with Mozaic 3+ platform with an all-new controller made on a 12nm fabrication process.

"To prevent disinformation from eroding democratic values worldwide, the U.S. must establish a global watermarking standard for text-based AI-generated content," writes retired U.S. Army Col. Joe Buccino in an opinion piece for The Hill. While President Biden's October executive order requires watermarking of AI-derived video and imagery, it offers no watermarking requirement for text-based content. "Text-based AI represents the greatest danger to election misinformation, as it can respond in real-time, creating the illusion of a real-time social media exchange," writes Buccino. "Chatbots armed with large language models trained with reams of data represent a catastrophic risk to the integrity of elections and democratic norms."

Joe Buccino is a retired U.S. Army colonel who serves as an A.I. research analyst with the U.S. Department of Defense Defense Innovation Board. He served as U.S. Central Command communications director from 2021 until September 2023. Here's an excerpt from his report:

Watermarking text-based AI content involves embedding unique, identifiable information -- a digital signature documenting the AI model used and the generation date -- into the metadata generated text to indicate its artificial origin. Detecting this digital signature requires specialized software, which, when integrated into platforms where AI-generated text is common, enables the automatic identification and flagging of such content. This process gets complicated in instances where AI-generated text is manipulated slightly by the user. For example, a high school student may make minor modifications to a homework essay created through Chat-GPT4. These modifications may drop the digital signature from the document. However, that kind of scenario is not of great concern in the most troubling cases, where chatbots are let loose in massive numbers to accomplish their programmed tasks. Disinformation campaigns require such a large volume of them that it is no longer feasible to modify their output once released.

The U.S. should create a standard digital signature for text, then partner with the EU and China to lead the world in adopting this standard. Once such a global standard is established, the next step will follow -- social media platforms adopting the metadata recognition software and publicly flagging AI-generated text. Social media giants are sure to respond to international pressure on this issue. The call for a global watermarking standard must navigate diverse international perspectives and regulatory frameworks. A global standard for watermarking AI-generated text ahead of 2024's elections is ambitious -- an undertaking that encompasses diplomatic and legislative complexities as well as technical challenges. A foundational step would involve the U.S. publicly accepting and advocating for a standard of marking and detection. This must be followed by a global campaign to raise awareness about the implications of AI-generated disinformation, involving educational initiatives and collaborations with the giant tech companies and social media platforms.

In 2024, generative AI and democratic elections are set to collide. Establishing a global watermarking standard for text-based generative AI content represents a commitment to upholding the integrity of democratic institutions. The U.S. has the opportunity to lead this initiative, setting a precedent for responsible AI use worldwide. The successful implementation of such a standard, coupled with the adoption of detection technologies by social media platforms, would represent a significant stride towards preserving the authenticity and trustworthiness of democratic norms.

A programmer in northern China has been ordered to pay more than 1 million yuan to the authorities for using a virtual private network (VPN), in what is thought to be the most severe individual financial penalty ever issued for circumventing China's "great firewall." The programmer, surnamed Ma, was issued with a penalty notice by the public security bureau of Chengde, a city in Hebei province, on August 18. The notice said Ma had used "unauthorised channels" to connect to international networks to work for a Turkish company. The police confiscated the 1.058m yuan ($145,092) Ma had earned as a software developer between September 2019 and November 2022, describing it as "illegal income," as well as fining him 200 yuan ($27).

Charlie Smith (a pseudonym), the co-founder of GreatFire.org, a website that tracks internet censorship in China, said: "Even if this decision is overturned in court, a message has been sent and damage has been done. Is doing business outside of China now subject to penalties?"
