Europe’s supermarkets hit by new wave of cyberattacks targeting fridges • POLITICO
Sam Clark:
»
Refrigerators in dozens of supermarkets in at least five EU countries were out of service on Monday, local news outlets reported, in what appears to be a repeat of cyberattacks that hit French stores last month.
As of Monday afternoon, there were news reports of incidents affecting supermarkets in Belgium, Luxembourg, Sweden, Ireland, the Netherlands and Estonia.
Several store managers told local media that refrigerator temperatures suddenly spiked to up to 50ºC. This mirrors the French incidents last month, in which attackers appeared to remotely manipulate the fridges’ defrosting mechanisms so that they overheated.
It’s not confirmed that the attacks are connected or used the same software vulnerabilities that hit French chains, though one supermarket spokesperson said the incident is a cyberattack “similar to the one in France.”
Ken Munro, a cybersecurity researcher, said in an interview that supermarkets should have disconnected their refrigerators and the devices used to monitor and remotely manage them from the Internet. “I don’t accept any other excuse … particularly in light of the earlier [attacks in France],” he said.
Inti De Ceukelaire, another cyber researcher, also said the incident suggests supermarkets did not take the necessary steps even after the France attacks. “It seems that some of them simply did not get patched, which is quite ridiculous,” he said.

Weak, out-of-date firmware on Danfoss systems which were (are) on the open web, rather than VPNs. Yet I get the feeling that this isn’t nation state hackers. It feels more like kids messing around. Both these hacks happened over a weekend, specifically on a Sunday – when script kiddies tend not to be at school. “I found a supermarket fridge that’s online and you can control the temperature LOL” is what I’d expect someone typed in a chatroom.

Binance’s $6bn hack is a dark day for all in crypto • Asia Tech Review
Jon Russell:
»
In moments like this, also, we are reminded just how decentralised crypto is. That’s to say, its rise to prominence came from the concept that it was a different paradigm to traditional finance. Users truly own their assets and the markets trade 24/7.
Except it doesn’t work that way. A number of companies stepped up to freeze assets and reverse transactions impacting the stolen funds. Around $3bn, or nearly half of the affected assets, were frozen, according to Binance. While that’s good for the company and it impacts the attacker, from an ideological perspective, it is proof that there’s centralisation. The idea that it is an alternative financial system hasn’t played out.
Binance, and other exchanges, are so often the entities that produce the worst news for the industry. Media coverage will have you believe that Binance is hugely popular and celebrated among people in the space and, whilst that’s true to a large extent in terms of its number of supporters, many influential people don’t like the company. It’s seen as greedy, arrogant and lax. Nobody asked for these organisations to represent the industry, and yet they so often do, particularly when it comes to the bad news cycles.
Following Binance’s last major hack in 2019, then a mere $40m in Bitcoin, CZ suggested the Bitcoin blockchain would be “rolled back” to reverse the losses. That is an absurd suggestion. Doing so would reverse all subsequent transactions that took place after Binance was hacked. It would set a dangerous precedent for the future. All because of Binance’s shortcomings. It didn’t happen but it showed the arrogance and greed of exchange businesses.
The fact that Binance quickly came out to say it would cover all lost funds (more than $6bn) shows just how much money the company makes. Added to those US fines, and the company has had more than $10bn removed from its funds in the last few years. Few businesses could withstand a hit like that, but exchanges make so much money and yet still are so fallible at best, or incompetent at worst.
Their business models are based around charging wide spreads for customer transactions and, when it comes to listing new tokens, demanding millions of dollars in tokens to make new assets available. Despite making billions in profits, their security systems lack sophistication and many have brazenly committed criminal activities.
The technology itself remains the big story, and that’s why banks, payment companies and others are adopting stablecoins for fast and cheap international payments, always-on trading strategies, tokenised stocks and other features that can genuinely improve traditional finance. There’s a lot more to delve into here.
Everyone loses in a huge hack like this, which reinforces the issues and inefficiencies of the crypto industry at large.
«
It’s almost as if the money flowing through these exchanges isn’t real – as in, you couldn’t exchange those claimed stolen billions for actual billions of dollars. Binance said it would reserve those $6bn in losses from this year’s revenues. That’s just insane, unless the entire underworld, and censured states, are moving their money through it. Which is, in fact, entirely possible given that Binance was fined $4bn in 2023 for enabling money laundering.

Failure and collapse of the Arecibo Observatory Telescope assessed by new report • National Academies of Science, Engineering and Medicine
»
A new report from the National Academies of Sciences, Engineering, and Medicine analyzes the causes of the 2020 collapse of the National Science Foundation’s telescope at the Arecibo Observatory in Puerto Rico, where NSF maintained research operations for its National Astronomy and Ionosphere Center, and draws lessons learned for other unique, critical science facilities.
Long-term zinc creep-induced failure in the 57-year-old telescope’s cable spelter sockets was the root cause of the telescope’s collapse, the report says. Sockets filled with zinc held in place a set of cables suspending the telescope’s main platform over the reflector dish. Gradually the zinc lost its hold on the cables and allowed several of them to pull out, leading to the collapse of the platform into the reflector.
The failure sequence began with Hurricane Maria, over three years prior to the collapse, according to the report. Indications of cable pullout were minimal before the hurricane. Large and progressive cable pullouts could be seen during post-hurricane visual inspections, observation of which should have prompted remedial action. Safety factor calculations made following the first cable failure did not recognize the accelerated time-dependent materials failure process governing the eventual zinc pull out.
This is the first documented case of long-term zinc-induced creep failure despite a long history of usage over a century, the report notes. A possible explanation for the accelerated zinc-creep is long-term low-current electroplasticity, induced by the electromagnetic waves from the Arecibo Telescope.«
In case you’d forgotten what it looked like (very dramatic).

Stack Exchange Data Explorer
You have to go and look at this graph to get the full effect. It’s the number of new questions asked, by month, on Stack Exchange, which used to be the hangout for programmers.
Back in August 2008, its second month, there were 3,744 questions. At the peak, in early 2014, there were 207,169. (That’s new questions – not just responses.) The last peak, in early 2020, was 186,376.
And since mid-2022 (you know what that was), it’s fallen off a cliff – so that for October, there were just 1,052 new questions. You might think this means (nearly) all the questions in programming have been answered. But the reality is that it’s all shifted to vibe coding.

Mystery of 60-second fluctuations in power grids solved • Forschungszentrum Jülich
»
Tennet Germany, the largest transmission system operator in Germany, has observed over several years that the frequency in the European power grid dips briefly every 60 seconds. While these deviations were not critical to grid security, they were clearly measurable and unusually regular. The cause of this phenomenon was initially unclear.
A team at Forschungszentrum Jülich led by Dirk Witthaut—who is also a professor at the Institute for Theoretical Physics at the University of Cologne—joined forces with other researchers from the University of Cologne and the Karlsruhe Institute of Technology to search for an answer—and they found it: the cause appears to be the many large-scale battery storage systems that check their state of charge every minute. This leads to measurable fluctuations in electricity consumption, which can contribute to turbine wear and tear, for example. The battery storage systems ensure an uninterrupted power supply, and their numbers have increased significantly worldwide in recent years. The researchers found that this was not a European phenomenon, but a global one.
“It really was years of detective work,” says Witthaut. The grid frequency pattern is shaped by many different factors. For example, it reveals the influence of electricity trading, with power stations being switched on and off abruptly, as well as the fluctuating feed-in from renewable energy sources, and various other disturbances.
“It quickly became clear to us that the cause must be something controlled by the clock,” says Witthaut. There was no other way to explain the precise 60-second cycle. It was also clear that: “The observed effect can only be produced if many devices are consuming electricity at the same time.” A single consumer or generator could therefore be ruled out.
…As there are no binding standards for such power checks, Witthaut suspects that most battery manufacturers assumed that a 60-second interval would be sensible. The start of every minute was simply chosen as the test time. “It is entirely possible, however, that battery storage systems are only part of the problem here,” says Witthaut. “It cannot be ruled out that other digitally controlled appliances – such as air-conditioning systems, heat pumps, washing machines, and dishwashers – may also exhibit similar patterns.”
«
Very obvious solution – a firmware update which gets them to do the test at a random moment during the minute (if a minute is necessary). Now we just need to get every manufacturer of battery storage systems to update their firmware before this becomes a real problem.

We asked six chatbots to make voter guides. They made serious errors • The Washington Post
Kevin Schaul and Ian Duncan:
»
A Missouri Senate race that doesn’t exist. A House candidate in Washington who isn’t really on the ballot. And AI-powered websites feeding chatbots questionable information.
More people are turning to chatbots in place of search engines, and 2 in 5 Americans said they had used artificial intelligence to look up election information in a recent survey by the National Conference on Citizenship. To test how reliable chatbots are with voting information, The Washington Post challenged six of the most popular to make voter guides for addresses in every county in the United States.
The results weren’t great.
AI chatbots frequently provided incorrect information, according to The Post’s analysis of more than 3,000 AI-generated voter guides — often as a result of citing websites with incorrect information that also appeared to have been produced with help from AI.
OpenAI and Anthropic have both touted partnerships to supply their chatbots with trusted election information, but those efforts did not prevent significant errors.
When asked to create a voter guide listing all of the races and candidates for an address in Missouri, ChatGPT included a US Senate seat that is not on the ballot this year. For an address in Wyoming, Anthropic’s Claude chatbot erroneously listed local politicians as running for federal office.
«
The story shows that the chatbots do throw up disclaimers telling people to confirm the details with voter hubs. But if people were going to do that, wouldn’t they be on the voter hub? And couldn’t we expect the chatbots, four years after the first ChatGPT, to do that? When Google was four years old it was able to direct people to the right sites for information.

The Tokenizer Tax: Why non-english AI users pay more for tokens • Rest of World
Ananya Bhattacharya:
»
People who use less widely spoken languages could end up paying more to use artificial intelligence than those who speak English or other dominant languages.
A new study published in September by the Coalition for Language Equity in AI Research found AI models require far more tokens for some languages than others. Tokens are the units of text or data that the models process. The researchers have called this a hidden “tokenizer tax,” which can make AI more expensive in languages with smaller online presence. A tokenizer is a tool that breaks down raw text, images, or audio into tokens.
Even within the 20 most popular languages on the internet, there is a gap in token usage, the research found. The most expensive of the languages used between 1.5 and 5 times more tokens than the cheapest. This gap widened when researchers expanded the set to 200 languages, with the token cost gap in one AI model growing by 17 times.
“A startup in [Bengaluru] may pay a surcharge on every prompt and completion while its competitor in Austin does not,” the study said. “The tokenizer tax also has implications beyond cost. Higher token counts translate into higher latency and reduced effective context capacity. These penalties hit hardest where compute and connectivity are already limited. Tokenizer inequity is a constraint on who can participate in the AI economy.”
Non-English languages leave less room for documents or conversation history, and require more work to generate the answer, according to Pratyush Choudhury, co-founder of Activate AI, India’s first venture capital fund dedicated exclusively to AI.

As political ad spending skyrockets, broadcast TV remains king • The New York Times
Katie Robertson:
»
The amount of money being spent on political advertising this election cycle is staggering, helping to boost the bottom lines of the biggest local broadcasting companies like Sinclair, Nexstar Media Group, Gray Media, Tegna and the E.W. Scripps Company.
The research firm S&P Global projects broadcast television advertising this year to be 15% higher than the last nonpresidential election year in 2022. And political ad revenue alone is expected to account for 16.3% of total broadcast revenue for the year, which would be a record for a nonpresidential election year.
During this election cycle, total political advertising is expected to reach $11.6bn by Election Day, according to AdImpact; $5.6bn (48%) is flowing to broadcast. That dollar figure is even higher than the one during the 2024 presidential race, when $5.3bn was spent on broadcast advertising, still 48% of the total.
That growth is an outlier in the overall advertising market, where TV’s share continues to shrink as do the overall dollars. In 2024, for example, TV made up 15% of all ad spending in the United States, according to the research firm eMarketer. This year, projections envision that figure to be 10%.
Nowhere is the broadcast TV blitz more evident than in Texas, where more than half a billion dollars will be spent in the Senate runoff, primaries and general election campaigns.
Oscar Rodriguez, the president of the Texas Association of Broadcasters, said stations in all 20 media markets across the state were seeing ad buys, rather than just a few individual markets. “This is an election where clearly every single vote is going to matter,” he said.
…“The kinds of people who tend to be very likely to vote in midterm elections tend to lean older,” Joshua Kalla, a professor of political science at Yale, said. “And those people still watch a whole bunch of broadcast TV.”
«
And that’s it, basically. They get bombarded with adverts on TV. It’s incredible that people tolerate it.

Netflix has lost the war on movie theatres • Indiewire
David Ehrlich:
»
The future that Ted Sarandos has brought to us (and us to) with the inflexible weight of a destiny is, to his great consternation, a future where people will only be willing to invest themselves in things that someone else has credibly invested themselves in first.
It’s no wonder that Netflix’s streaming competitors have suffered from similar woes in this space. “F1” and “Killers of the Flower Moon” did major numbers at home on the backs of robust theatrical rollouts, while most movies that went straight to Apple TV barely seem to exist. Remember the Justin Timberlake vehicle “Palmer”? Apparently I wrote like 1,200 words about it. What about “Wolfs,” the George Clooney/Brad Pitt/Austin Abrams action-comedy that pivoted away from a wide release less than six weeks before it came out, immediately became Apple TV’s most-viewed film ever, and then sank into the bottomless abyss of lost media just as fast? Not lost, I suppose, but hiding in plain sight.
It’s likewise no wonder that the one Netflix movie that blossomed into a bona fide sensation, of the roughly 1,000 original films they’ve released since 2015, was 1.) produced outside the company, 2.) clearly excellent, and 3.) squarely targeted at children who could obsess over it with their friends all summer long and inhabit its characters through dress-up and singing. “K-Pop Demon Hunters” was a perfect vessel for the kind of engagement Netflix’s entire business model exists to diminish, and I suspect its success was a wake-up call — or at least an early warning sign — that Netflix desperately needed to be saved from itself.
To the company’s sincere credit, they’ve recently made strides towards that end. Netflix’s org chart might be in crisis, and its subscribers are growing increasingly restless about the awful cadence of content worth caring about. But the inevitable pivot toward real theatrical releases will meaningfully raise the profile of their exclusive film titles in the coming months, even if few of them perform as well as “La Bola Negra” has so far.
That pivot represents a rare about-face for a tech giant that has sought to remake the world in its own image, consumer happiness be damned.

Netflix’s struggles are fascinating: it won streaming, and then it turned out that streaming wasn’t a thing where winning counted for as much as it thought. And the way that content can just sink into the endless swirl is remarkable.
