Why GPS Fails In Cities. And What Researchers Think Could Fix It
13 October 2025 @ 2:40 am
ScienceDaily reports:
Our everyday GPS struggles in "urban canyons," where skyscrapers bounce satellite signals, confusing even advanced navigation systems. Norwegian University of Science and Technology (NTNU) scientists created SmartNav, combining satellite corrections, wave analysis, and Google's 3D building data for remarkable precision. Their method achieved accuracy within 10 centimeters during testing [90% of the time]. The breakthrough could make reliable urban navigation accessible and affordable worldwide...
"Cities are brutal for satellite navigation," explained Ardeshir Mohamadi. Mohamadi, a doctoral fellow at NTNU, is researching how to make affordable GPS receivers (like those found in smartphones and fitness watches) much more precise without depending on expensive external correction services.
Russia Accused of Severing Ukrainian Nuclear Power Plant's Link, as Energy Remains a 'Key Battleground'
13 October 2025 @ 1:40 am
It's the largest nuclear power plant in Europe. But "Ukraine's foreign minister accused Russia on Sunday of deliberately severing the external power line to the Russian-held Zaporizhzhia nuclear power station," reports Reuters, "in order to link the plant to Moscow's power grid."
Ukrainian Foreign Minister Andrii Sybiha said Moscow was attempting to test a reconnection to Russia's grid. Ukraine has long feared that Moscow would try to redirect the plant's output to its grid. But Russian officials have denied any intention of trying to restart the plant, seized by Moscow's forces in the early weeks of the February 2022 invasion of Ukraine.
The plant produces no electricity at the moment, but has been without an external electricity source for nearly three weeks. Officials have relied on emergency diesel generators to secure the power needed to keep the fuel cool inside the facility and guard against a meltdown. "Russia intentionally broke the plant's connection with the Ukrainian gri
AMD Amps Up Chip War - But Nvidia's Still Leading
12 October 2025 @ 11:43 pm
The Wall Street Journal marvelled at AMD's "game-changing deal" this week with OpenAI, calling it "the culmination of an extraordinary, decade-long turnaround effort, solidifying AMD's status as Nvidia's most legitimate competitor."
Shortly after taking charge of the company in 2014, [CEO] Su implemented a systematic plan to eat Intel's lunch, which she accomplished by going after Intel's main product lines while it was bogged down by manufacturing problems. Now, Su has set her sights on Nvidia, the $4.5 trillion chips behemoth led by her cousin, Jensen Huang. Some analysts believe that if Su can sign up more big customers for its AI chips, AMD could join the $1 trillion valuation club before too long.
"With this, it's natural to ask: Did AMD just say checkmate to Nvidia?" asks the Motley Fool investment site. But their answer seems to be "no"...
AMD has increased its push into the AI market over the past few years, launching the AMD Instinct line of accelerators, and in the lates
Toxic Workplaces Are Worsening: 80% of U.S. Workers Say Their Job Hurts Mental Health
12 October 2025 @ 9:44 pm
Slashdot reader joshuark shared this report from Fast Company:
According to Monster's newly released 2025 Mental Health in the Workplace survey of 1,100 workers, 80% of respondents described their workplace environment as toxic. The alarming statistic is an increase from 67% just a year ago.
The challenging environment has major implications. An astonishing 71% of workers say their mental health is poor (40%) or fair (31%), while only 29% rank it positively: 20% said it was good and 9% described it as great. Workers say that a toxic workplace culture is the top cause of their poor mental health (59%), followed closely by having a bad manager (54%)...
Mental health is incredibly important to employees. The majority (63%) care more about it than having a "brag-worthy" job. Likewise, many would pass on a promotion (43%) or opt out of a raise (33%) if it was better for their mental health... The vast majority (93%) say their employer isn't focused on supporting employee mental health
There's No 'AI Bubble', Says Yahoo Finance Executive Editor
12 October 2025 @ 8:44 pm
"I'm here to say we have to give these AI bubble predictions a rest," says Yahoo Finance executive editor Brian Sozzi.
First of all, AI is a real technology being deployed in real ways inside of Corporate America. Second, this technology is requiring more physical assets in the ground — which are being built to support AI's real-world application. What Zach Dell (son of Michael Dell) is working on at startup Base Power (which just raised $1 billion) impressed me this week. It's addressing a key issue — power availability and costs in part because of rising stress on the grid due to AI development.
Next, the spending on AI infrastructure doesn't strike me as reckless. I talk to CFOs and they walk me through their thinking, which seems logical. They aren't foaming at the mouth with wild-eyed predictions of grandeur similar to the late '90s. Plus, the tech giants making the biggest AI investments are fueling their ambitions by cash on hand — not loading up balance she
Amazon Smart Displays Are Now Being Bombarded With Ads
12 October 2025 @ 7:44 pm
"Amazon Echo Show owners are reporting an uptick in advertisements on their smart displays," reports Ars Technica.
The company's Echo Show smart displays have previously shown ads through the company's Shopping Lists feature, as well as advertising for Alexa skills. Additionally, Echo Shows may play audio ads when users listen to Amazon Music on Alexa. However, reports on Reddit (examples here, here, and here) and from The Verge's Jennifer Pattison Tuohy, who owns more than one Echo Show, suggest that Amazon has increased the amount of ads it shows on its smart displays' home screens.
The Echo Show's apparent increase in ads is pushing people to stop using or even return their Echo Shows.
The article notes Amazon's smart displays have also started showing ads for Alexa+ — and The Verge's reporter saw ads on one (but not all) of her Echo Shows this week. (Even when the display is set to show personal photos, ads sometimes appear for herbal supplements, Quest sports chips, a
'Death to Spotify' Event Draws Interest From Some Musicians to Try Alternatives
12 October 2025 @ 5:58 pm
An anonymous reader shared this report from the Guardian:
This month, indie musicians in San Francisco gathered for a series of talks called Death to Spotify, where attenders explored "what it means to decentralize music discovery, production and listening from capitalist economies". The events, held at Bathers library, featured speakers from indie station KEXP, labels Cherub Dream Records and Dandy Boy Records, and DJ collectives No Bias and Amor Digital. What began as a small run of talks quickly sold out and drew international interest. People as far away as Barcelona and Bengaluru emailed the organizers asking how to host similar events.
The talks come as the global movement against Spotify edges into the mainstream. In January, music journalist Liz Pelly released Mood Machine, a critical history arguing the streaming company has ruined the industry and turned listeners into "passive, uninspired consumers". Spotify's model, she writes, depends on paying artists a pittance —
Three-Wheeled Solar Car Maker Aptera is About to Go Public
12 October 2025 @ 4:34 pm
Last November Aptera successfully tested its first production-intent three-wheel solar-powered EV — and said it already had over 50,000 reservations. The vehicles had a solar charge range of 40 miles per day, reported Digital Trends, noting the crowdfunded company's cars also had an NCAS charging port. ("Solar-powered electric vehicles are also being developed by the likes of Germany's Sono Motors and the Netherlands' Lightyear, and by big automakers such as Hyundai and Mercedes-Benz.")
But this week the EV site Electrek pointed out that "There have been a handful of 'solar car' projects and they all have failed so far."
Aptera is one of the rare survivors, thanks to a couple of relatively successful crowdfunding efforts. The company has been inching closer to bringing its vehicle to production, but it still appears to need some investments to make it happen. Now, Aptera is going public.
Generally, that's good news. An initial public offering (IPO) means that a company is goi
AI Slop? Not This Time. AI Tools Found 50 Real Bugs In cURL
12 October 2025 @ 3:34 pm
The Register reports:
Over the past two years, the open source curl project has been flooded with bogus bug reports generated by AI models. The deluge prompted project maintainer Daniel Stenberg to publish several blog posts about the issue in an effort to convince bug bounty hunters to show some restraint and not waste contributors' time with invalid issues. Shoddy AI-generated bug reports have been a problem not just for curl, but also for the Python community, Open Collective, and the Mesa Project.
It turns out the problem is people rather than technology. Last month, the curl project received dozens of potential issues from Joshua Rogers, a security researcher based in Poland. Rogers identified assorted bugs and vulnerabilities with the help of various AI scanning tools. And his reports were not only valid but appreciated. Stenberg in a Mastodon post last month remarked, "Actually truly awesome findings." In his mailing list update last week, Stenberg said, "most of them were tiny
California 'Privacy Protection Agency' Targets Tractor Supply's Tricky Tracking
12 October 2025 @ 2:34 pm
California's Privacy Protection Agency "issued a record fine earlier this month to Tractor Supply," according to an EFF Deeplinks blog post — for "apparently ducking its responsibilities under the California Consumer Privacy Act."
Under that law, companies are required to respect California customers' and job applicants' rights to know, delete, and correct information that businesses collect about them, and to opt-out of some types of sharing and use. The law also requires companies to give notice of these rights, along with other information, to customers, job applicants, and others. The CPPA said that Tractor Supply failed several of these requirements. This is the first time the agency has enforced this data privacy law to protect job applicants...
Tractor Supply, which has 2,500 stores in 49 states, will pay for their actions to the tune of $1,350,000 — the largest fine the agency has issued to date. Specifically, the agency said, Tractor Supply violated the law by:
