Astronomers have discovered a supermassive black hole in the early Universe devouring matter at over 40 times the Eddington limit. ScienceAlert reports: Led by astronomer Hyewon Suh of Gemini Observatory and NSF's NOIRLab, a team of researchers used JWST to take follow-up observations of a smattering of galaxies identified by the Chandra X-ray Observatory that were bright in X-rays but dim in other wavelengths. When they got to LID-568, they were having trouble identifying its distance across space-time. The galaxy was very faint and very hard to see; but, using the integral field spectrograph on JWST's NIRSpec instrument, the team homed in on the galaxy's exact position. LID-568's far-off location is surprising. Although the object is faint from our position in the Universe, its distance means it must be incredibly intrinsically bright. Detailed observations revealed powerful outflows from the supermassive black hole, a signature of accretion as some of the material is being diverted and blasted into space. A painstaking analysis of the data revealed that the supermassive black hole is a relatively small one, as supermassive black holes go; just 7.2 million times the mass of the Sun. And the amount of light being produced by the material around the disk was much, much higher than a black hole of this mass should be capable of producing. It suggests an accretion rate some 40 times higher than the Eddington limit. At this rate, the period of super-Eddington accretion should be extremely brief, which means Suh and her team were extremely lucky to catch it in action. And we expect that LID-568 will become a popular observation target for black hole scientists, allowing us a rare glimpse into super-Eddington processes. The research has been published in Nature Astronomy.

Since it's election day in the US, many people are thinking about counting today. We frequently discuss counting here, and how to do it wrong, so let's look at some code from RK.

This code may not be counting votes, but whatever it's counting, we're not going to enjoy it:

case LogMode.Row_limit: // row limit excel = 65536 rows if (File.Exists(personalFolder + @"\" + fileName + ".CSV")) { using (StreamReader reader = new StreamReader(personalFolder + @"\" + fileName + ".CSV")) { countRows = reader.ReadToEnd().Split(new char[] { '\n' }).Length; } }

Now, this code is from a rather old application, originally released in 2007. So the comment about Excel's row limit really puts us in a moment in time- Excel 2007 raised the row limit to 1,000,000 rows. But older versions of Excel did cap out at 65,536. And it wasn't the case that everyone just up and switched to Excel 2007 when it came out- transitioning to the new Office file formats was a conversion which took years.

But we're not even reading an Excel file, we're reading a CSV.

I enjoy that we construct the name twice, because that's useful. But the real magic of this one is how we count the rows. Because while Excel can handle 65,536 rows at this time, I don't think this program is going to do a great job of it- because we read the entire file into memory with ReadToEnd, then Split on newlines, then count the length that way.

As you can imagine, in practice, this performed terribly on large files, of which there were many.

Unfortunately for RK, there's one rule about old, legacy code: don't touch it. So despite fixing this being a rather easy task, nobody is working on fixing it, because nobody wants to be the one who touched it last. Instead, management is promising to launch a greenfield replacement project any day now…

An anonymous reader quotes a report from The Guardian: Sweden has vetoed plans for 13 offshore windfarms in the Baltic Sea, citing unacceptable security risks. The country's defence minister, Pal Jonson, said on Monday that the government had rejected plans for all but one of 14 windfarms planned along the east coast. The decision comes after the Swedish armed forces concluded last week that the projects would make it more difficult to defend Nato's newest member. The proposed windfarms would have been located between Aland, the autonomous Finnish region between Sweden and Finland, and the Sound, the strait between southern Sweden and Denmark. The Russian exclave of Kaliningrad is only about 310 miles (500km) from Stockholm. Wind power could affect Sweden's defence capabilities across sensors and radars and make it harder to detect submarines and possible attacks from the air if war broke out, Jonson said. The only project to receive the green light to was Poseidon, which will include as many as 81 wind turbines to produce 5.5 terawatt hours a year off Stenungsund on Sweden's west coast. "Both ballistic robots and also cruise robots are a big problem if you have offshore wind power," Jonson said. "If you have a strong signal detection capability and a radar system that is important, we use the Patriot system for example, there would be negative consequences if there were offshore wind power in the way of the sensors."

According to The Verge, Netflix plans to delist almost all of its interactive shows and films as of December 1st. Only four of the 24 interactive titles will remain: Black Mirror: Bandersnatch, Unbreakable Kimmy Schmidt: Kimmy vs. the Reverend, Ranveer vs. Wild with Bear Grylls, and You vs. Wild. From the report: The removal of the titles marks a disappointing conclusion to Netflix's earliest efforts into interactive content. The company first launched the interactive titles in 2017 with Puss in Book: Trapped in an Epic Tale, and I remember being wowed (and horrified) by paths in Black Mirror: Bandersnatch. In addition to specials based on franchises like Carmen Sandiego and Boss Baby, Netflix also tried ideas like a daily trivia series and a trivia game you could play with a friend. But the relatively few titles available suggests the format wasn't much of a hit -- Puss in Book has apparently been gone for a while. "The technology served its purpose, but is now limiting as we focus on technological efforts in other areas," spokesperson Chrissy Kelleher says.

Leading fintech and digital asset firms, including Robinhood, Kraken and Galaxy Digital, have introduced a joint stablecoin pegged to the U.S. dollar. Called the Global Dollar Network, it seeks to enhance the stablecoin market by lowering transaction costs, boosting consumer protections, and facilitating cross-border transactions with rewards for institutional participants. Crypto Briefing reports: The network will utilize Paxos's new stablecoin, the Global Dollar (USDG), which complies with the Monetary Authority of Singapore's upcoming stablecoin framework. USDG is designed to return yield on reserve assets to participants who contribute to its adoption, encouraging the development of crypto and financial solutions using the token. The Global Dollar Network aims to address shortcomings in the stablecoin market, such as high transaction costs and limited consumer protections. The network has opened an invite-only phase for select custodians, exchanges, payment processors, merchants, and banks to develop new solutions using USDG. Initial distribution is available on Anchorage Digital, Galaxy Digital, Kraken, and Paxos platforms, with plans to expand access through additional partners in the coming months.

An anonymous reader quotes a report from TechCrunch: The CEO of AI search company Perplexity, Aravind Srinivas, has offered to cross picket lines and provide services to mitigate the effect of a strike by New York Times tech workers. The NYT Tech Guild announced its strike Monday, after setting November 4 as its deadline months earlier. The workers represented provide software support and data analysis for the Times, on the business side of the outlet. They have been asking for an annual 2.5% wage increase and to cement a current two days per week in-office expectation, among other things. [...] Picketers demonstrated in front of the NYT building in New York as negotiations continued. Meanwhile, on X, formerly known as Twitter, Perplexity's CEO offered to step in for the striking workers. Replying to Semafor media editor Max Tani quoting the publisher, Srinivas wrote: "Hey AG Sulzberger @nytimes sorry to see this. Perplexity is on standby to help ensure your essential coverage is available to all through the election. DM me anytime here." Many on X immediately castigated Srinivas for acting as a scab -- a derogatory term for people willing to perform the jobs of striking workers. It is widely considered a disreputable behavior in matters of labor and equity. By undercutting collective action, scabs limit the ability of workers to bargain with those in positions of power. Srinivas may simply be trying to make sure people have the information they need on election day. The company has lately unveiled its own elections info hub and map. But to offer its services explicitly as a replacement for striking workers was bound to be an unpopular move. Though TechCrunch asked Perplexity for comment, Srinivas responded to TechCrunch's post on X saying that "the offer was *not* to 'replace' journalists or engineers with AI but to provide technical infra support on a high-traffic day." The striking workers in question, however, are the ones who provide that service to the NYT. It's not really clear what services other than AI tools Perplexity could offer, or why they would not amount to replacing the workers in question.

Amazon's Prime Video has introduced "X-Ray Recaps," a generative AI feature that will recap what you're watching. The new tool can create text summaries of "full seasons of TV shows, single episodes, and even pieces of episodes," the company says in a blog post. The Verge reports: X-Ray Recaps will be accessible from the detail page of a show or in X-Ray while you're watching something. The tool "analyzes various video segments, combined with subtitles or dialogue, to generate detailed descriptions of key events, places, times, and conversations," Amazon says. Amazon has also applied "guardrails" to help the feature avoid sharing spoilers and to keep summaries concise. X-Ray Recaps, which is are beta, are coming to Fire TV devices starting today, with support for "additional devices" available by the end of this year, Amazon says. The feature, at launch, will work with all Amazon MGM Studios Original series.

Anton Shilov reports via Tom's Hardware: FFmpeg is an open-source video decoding project developed by volunteers who contribute to its codebase, fix bugs, and add new features. The project is led by a small group of core developers and maintainers who oversee its direction and ensure that contributions meet certain standards. They coordinate the project's development and release cycles, merging contributions from other developers. This group of developers tried to implement a handwritten AVX512 assembly code path, something that has rarely been done before, at least not in the video industry. The developers have created an optimized code path using the AVX-512 instruction set to accelerate specific functions within the FFmpeg multimedia processing library. By leveraging AVX-512, they were able to achieve significant performance improvements -- from three to 94 times faster -- compared to standard implementations. AVX-512 enables processing large chunks of data in parallel using 512-bit registers, which can handle up to 16 single-precision FLOPS or 8 double-precision FLOPS in one operation. This optimization is ideal for compute-heavy tasks in general, but in the case of video and image processing in particular. The benchmarking results show that the new handwritten AVX-512 code path performs considerably faster than other implementations, including baseline C code and lower SIMD instruction sets like AVX2 and SSSE3. In some cases, the revamped AVX-512 codepath achieves a speedup of nearly 94 times over the baseline, highlighting the efficiency of hand-optimized assembly code for AVX-512.

An anonymous reader quotes a report from Ars Technica: On Friday, Perplexity launched an election information hub that relies on data from The Associated Press and Democracy Works to provide live updates and information about the 2024 US general election, which takes place on Tuesday, November 5. "Starting Tuesday, we'll be offering live updates on elections using data from The Associated Press so you can stay informed on presidential, senate, and house races at both a state and national level," Perplexity wrote in a blog post. The site will pull data from special data sources (called APIs) hosted by the two organizations. As of Monday, Perplexity's hub currently provides interactive information on voting requirements, poll times, and summaries about ballot measures, candidates, policy positions, and endorsements. Users can ask questions about the information similar to using a chatbot like ChatGPT. Perplexity's embrace of providing election information is an exception in the AI field. Wary about accidentally providing misinformation, competitor AI assistants from OpenAI, Google, and Anthropic currently direct users elsewhere or decline to answer election questions. OpenAI's ChatGPT Search directs election result queries to The Associated Press and Reuters. Perplexity describes its new elections hub as "an entry point for understanding key issues." But like other AI models, Perplexity can produce confabulations (plausible incorrect information) when generating responses. That could present an accuracy problem because the site's Voter Guide service uses AI language models to summarize and interpret information pulled from the web. Here's what Ars Technica advises: "Take what you see on Perplexity's site with a huge grain of salt -- do not rely on it without verifying the information with a trustworthy external source."

An anonymous reader shares a report: With Windows 11 still failing to set the world alight, campaigners are warning that millions of perfectly good PCs could become landfill fodder when support for Windows 10 runs out in eleven and a bit months. Figures compiled by StatCounter show that Windows 11 commanded a 35.55 percent share of the desktop Windows market in October. In comparison, the share of Windows 10 dropped to 60.97 percent, continuing a downward trend that began earlier this year -- it was still at 69.9 percent in April. Unless there is some marked acceleration, Windows 11 is unlikely to dominate the market by the time Microsoft pulls the plug on free updates for most of the Windows 10 world on October 14, 2025.

Singapore plans to boost road capacity by 20,000 vehicles through a new satellite-based road pricing system, the Land Transport Authority (LTA) announced last week. The city-state will replace its current gantry-based Electronic Road Pricing (ERP) system with GPS tracking technology, enabling more precise congestion management without physical toll stations. The Register adds: "ERP 2.0 will provide more comprehensive aggregated traffic information and will be able to operate without physical gantries. We will be able to introduce new 'virtual gantries,' which allow for more flexible and responsive congestion management," explained the LTA. But the island's government doesn't just control inflow into urban areas through toll-like charging -- it also aggressively controls the total number of cars operating within its borders. Singapore requires vehicle owners to bid for a set number of Certificates of Entitlement -- costly operating permits valid for only ten years. The result is an increase of around SG$100,000 ($75,500) every ten years, depending on that year's COE price, on top of a car's usual price. The high total price disincentivizes mass car ownership, which helps the government manage traffic and emissions.

A former teacher has filed a federal lawsuit against PowerSchool, alleging the education technology giant illegally sells student data to third parties without proper consent. Emily Cherkin, lead plaintiff in the class action suit filed in San Francisco, claims PowerSchool has amassed 345 terabytes of data from 440 school districts, including sensitive information about students' health, behavior, and academic records. The company provides software services to more than 60 million students across 90 of the largest U.S. school districts. The lawsuit alleges PowerSchool sells anonymized student data to over 100 partners, including educational consultants and government agencies, while marketing its analytics for workforce and policy planning. The company's Naviance college-planning software alone tracks 6 million high school students. PowerSchool has denied the allegations.

Netflix's gaming division is shifting focus to generative AI weeks after shuttering its premium game studio and laying off 35 developers, the company's newly appointed VP of GenAI for Games has announced. Mike Verdu, previously Vice President of Games, called the move a "once in a generation inflection point" that will "accelerate development" and create novel gaming experiences. The pivot follows the closure of Blue, Netflix's internal studio that had recruited veterans from major franchises including Call of Duty and God of War. "Pay no mind to uninformed speculation," Verdu wrote on LinkedIn, describing recent changes as a "planned transition."

A hardware hacker has successfully modified Nintendo's $100 Alarmo device to run the classic video game Doom, marking another milestone in the gaming community's tradition of porting the 1993 shooter to unconventional devices. YouTuber GaryOderNichts demonstrated the 2.8-inch circular alarm clock running Chocolate Doom natively, using the device's wheel for movement and side buttons for weapons. The hack requires no hardware modifications and works on the current 2.0 software version. The hack came after researchers discovered vulnerabilities in the Alarmo's STM32H7 microcontroller, enabling custom firmware installation through its USB-C port. The trick omits audio due to memory restrictions, GaryOderNichts notes, but it allows for custom animations and displays.

Cybercriminals have breached dozens of major companies including AT&T, Ticketmaster and Hot Topic by exploiting "infostealer" malware that harvests login credentials from infected computers, an investigation has found. The malware, spread through pirated software and social media, has infected 250,000 new devices daily, according to cybersecurity firm Recorded Future. Russian developers create the malware while contractors distribute it globally, deliberately avoiding former Soviet states. Hot Topic suffered potentially the largest retail hack ever in October when attackers accessed 350 million customer records using stolen developer credentials. Google and Microsoft are racing to patch vulnerabilities, but malware makers quickly adapt to new security measures.

App developers Musi and Sarafan Mobile have sued Apple and Google in California federal court over app removals they claim were unjustified, highlighting tensions over the tech giants' intellectual property enforcement policies. Musi's music-streaming app was removed after YouTube complained about interface infringement, while Sarafan's "Reely" app was taken down following Instagram's claims about logo similarity. Both developers say the platforms breached their agreements by removing apps without sufficient evidence. The lawsuits underscore broader concerns about Apple and Google's dominance in app distribution. Their private IP dispute systems operate outside traditional legal frameworks, with platforms making unilateral decisions that can effectively shut down businesses, according to University of New Hampshire law professor Peter Karol. [...] "In a court proceeding, you can see here's a complaint with the allegations, and then we have the defendant respond, and then we have a judge come out with an opinion saying, 'Is the mark valid? Is the mark infringed?'" said Lisa Ramsey, law professor at University of San Diego. Google and Apple's systems, meanwhile, are "a black box."

An anonymous reader shares a report: Another illegal streaming app has made its way to the App Store -- but it only surfaces pirated films for people in certain regions outside the US, including France, Canada, and the Netherlands. As shown in a post on Threads, the App Store listing for "Univer Note" presents itself as a productivity platform that can "easily help you record every day's events and plan your time." However, if you're a user in certain countries, like France or Canada, opening the app shows a collection of pirated movies, such as Venom: The Last Dance, Joker: Folie a Deux, and Terrifier 3.

The clash between law's need for finality and science's evolving nature is creating serious justice problems, an opinion piece on Scientific American argued on Monday. Two recent cases highlight this: Robert Roberson faces execution based on now-discredited shaken baby syndrome science, while the Menendez brothers' life sentences are being questioned due to improved understanding of childhood trauma's effects on violence. Scientific understanding in criminal justice has repeatedly proven wrong. Texas executed Cameron Todd Willingham in 2004 based on invalidated arson science. The FBI found errors in 90% of their reviewed hair analysis cases. Courts still accept bite mark evidence despite experts failing to distinguish human from animal bites. The legal system fails in two critical ways, the story argues: Judges don't properly screen out bad science despite their "gatekeeper" role established in Daubert v. Merrell Dow, and courts resist reopening cases when scientific understanding changes. While some states like Texas and California have laws allowing appeals based on updated science, implementation remains weak. Roberson has spent 20 years on death row and the Menendez brothers 28 years in prison while courts drag their feet on reviewing their cases with current scientific knowledge. The piece argues that constitutional due process requires allowing convicts to challenge their cases when the science underlying their convictions proves faulty. The system can reform by enforcing stricter scientific evidence standards and creating clear paths to challenge convictions based on outdated science.

An anonymous reader shares a report: As world leaders gathered in Colombia this week, they also watched for news from home, where many of the headlines carried the catastrophic consequences of ecological breakdown. Across the Amazon rainforest and Brazil's enormous wetlands, relentless fires had burned more than 22m hectares (55m acres). In Spain, the death toll in communities devastated by flooding passed 200. In the boreal forests that span Siberia, Scandinavia, Alaska and Canada, countries were recording alarming signs that their carbon sinks were collapsing under a combined weight of drought, tree death and logging. As Canada's wildfire season crept to a close, scientists calculated it was the second worst in two decades -- behind only last year's burn, which released more carbon than some of the world's largest emitting countries. In global negotiations, climate and nature move along two independent tracks, and for years were broadly treated as distinct challenges. But as negotiations closed at the Cop16 biodiversity summit in Cali on Saturday, ministers from around the world underscored the crucial importance of nature to limiting damage from global heating, and vice versa -- emphasising that climate and biodiversity could no longer be treated as independent issues if either crisis was to be resolved. Countries agreed a text on links between the climate and nature, but failed to include language on a phase out of fossil fuels. The UK environment secretary, Steve Reed, said that attending the summit in Colombia had brought home the links between climate and biodiversity. "One of the other things that's really struck me coming here and speaking to the Colombians in particular is how for them the nature crisis and the climate crisis are exactly the same thing. In the UK, perhaps more widely in the global north, we tend to talk a lot about climate and particularly net zero, and much less about nature -- perhaps because we're already more nature-depleted. But those two things connect entirely," he said. The Cop16 president, Susana Muhamad, Colombia's environment minister, has sought to put nature on a level with global efforts to decarbonise the world economy during the summit, warning that slashes to greenhouse gas emissions must be accompanied by the protection and restoration of the natural world if they are to be effective. Her presidency has repeatedly described nature and climate as "two sides of the same coin."
