'Linux Foundation Energy' Partners With US Government on Interoperability of America's EV Charging (substack.com) 21

The non-profit Linux Foundation Energy hopes to develop energy-sector solutions (including standards, specifications, and software) supporting rapid decarbonization by collaborating with industry stakeholders.

And now they're involved in a new partnership with America's Joint Office of Energy — which facilitates collaboration between the federal Department of Energy and its Department of Transportation. The partnership's goal? To "build open-source software tools to support communications between EV charging infrastructure and other systems."

The Buildout reports: The partnership and effort — known as "Project EVerest" — is part of the administration's full-court press to improve the charging experience for EV owners as the industry's nationwide buildout hits full stride. "Project EVerest will be a game changer for reliability and interoperability for EV charging," Gabe Klein, executive director of the administration's Joint Office of Energy and Transportation, said yesterday in a post on social media....

Administration officials said that a key driver of the move to institute broad standards for software is to move beyond an era of unreliable and disparate EV charging services throughout the U.S. Dr. K. Shankari, a principal software architect at the Joint Office of Energy and Transportation, said that local and state governments now working to build out EV charging infrastructure could include a requirement that bidding contractors adhere to Project EVerest standards. That, in turn, could have a profound impact on providers of EV charging stations and services by requiring them to adapt to open source standards or lose the opportunity to bid on public projects. Charging availability and reliability are consistently mentioned as key turnoffs for potential EV buyers who want the infrastructure to be ready, easy, and consistent to use before making the move away from gas cars.

Specifically, the new project will aim to create what's known as an open source reference implementation for EV charging infrastructure — a set of standards that will be open to developers who are building applications and back-end software... And, because the software will be available for any company, organization, or developer to use, it will allow the creation of new EV infrastructure software at all levels without software writers having to start from scratch. "LF Energy exists to build the shared technology investment that the entire industry can build on top of," said Alex Thompson of LF Energy during the web conference. "You don't want to be re-inventing the wheel."

The tools will help communication between charging stations (and adjacent chargers), as well as vehicles and batteries, user interfaces and mobile devices, and even backend payment systems or power grids. An announcement from the Joint Office of Energy and Transportation says this software stack "will reduce instances of incompatibility resulting from proprietary systems, ultimately making charging more reliable for EV drivers." "The Joint Office is paving the way for innovation by partnering with an open-source foundation to address the needs of industry and consumers with technical tools that support reliable, safe and interoperable EV charging," said Sarah Hipel, Standards and Reliability Program Manager at the Joint Office.... With this collaborative development model, EVerest will speed up the adoption of EVs and decarbonization of transportation in the United States by accelerating charger development and deployment, increase customizability, and ensure high levels of security for the nation's growing network.
Linux Foundation Energy adds that reliable charging "is key to ensuring that anyone can confidently choose to ride or drive electric," predicting it will increase customizability for different use cases while offering long-term maintainability, avoiding vendor-lock in, and ensuring high levels of security. This is a pioneering example of the federal government collaborating to deploy code into an open source project...

"The EVerest project has been demonstrated in pilots around the world to make EV charging far more reliable and reduces the friction and frustration EV drivers have experienced when a charger fails to work or is not continually maintained," said LF Energy Executive Director Alex Thornton. "We look forward to partnering with the Joint Office to create a robust firmware stack that will stand the test of time, and be maintained by an active and growing global community to ensure the nation's charging infrastructure meets the needs of a growing fleet of electric vehicles today and into the future."

The Atlantic Warns of a Rising 'Authoritarian Technocracy' (theatlantic.com) 70

In the behavior of tech companies, the Atlantic's executive editor warns us about "a clear and coherent ideology that is seldom called out for what it is: authoritarian technocracy. As the most powerful companies in Silicon Valley have matured, this ideology has only grown stronger, more self-righteous, more delusional, and — in the face of rising criticism — more aggrieved." The new technocrats are ostentatious in their use of language that appeals to Enlightenment values — reason, progress, freedom — but in fact they are leading an antidemocratic, illiberal movement. Many of them profess unconditional support for free speech, but are vindictive toward those who say things that do not flatter them. They tend to hold eccentric beliefs.... above all, that their power should be unconstrained. The systems they've built or are building — to rewire communications, remake human social networks, insinuate artificial intelligence into daily life, and more — impose these beliefs on the population, which is neither consulted nor, usually, meaningfully informed. All this, and they still attempt to perpetuate the absurd myth that they are the swashbuckling underdogs.
The article calls out Marc Andreessen's Techno-Optimist Manifesto for saying "We believe in adventure... rebelling against the status quo, mapping uncharted territory, conquering dragons, and bringing home the spoils for our community..." (The Atlantic concludes Andreessen's position "serves only to absolve him and the other Silicon Valley giants of any moral or civic duty to do anything but make new things that will enrich them, without consideration of the social costs, or of history.")

The article notes that Andreessen "also identifies a list of enemies and 'zombie ideas' that he calls upon his followers to defeat, among them 'institutions' and 'tradition.'" But the Atlantic makes a broader critique not just of Andreessen but of other Silicon Valley elites. "The world that they have brought into being over the past two decades is unquestionably a world of reckless social engineering, without consequence for its architects, who foist their own abstract theories and luxury beliefs on all of us..." None of this happens without the underlying technocratic philosophy of inevitability — that is, the idea that if you can build something new, you must. "In a properly functioning world, I think this should be a project of governments," [Sam] Altman told my colleague Ross Andersen last year, referring to OpenAI's attempts to develop artificial general intelligence. But Altman was going to keep building it himself anyway. Or, as Zuckerberg put it to The New Yorker many years ago: "Isn't it, like, inevitable that there would be a huge social network of people? ... If we didn't do this someone else would have done it."
The article includes this damning chat log from a 2004 conversation Zuckerberg had with a friend:

Zuckerberg: If you ever need info about anyone at Harvard.
Zuckerberg: Just ask.
Zuckerberg: I have over 4,000 emails, pictures, addresses, SNS
Friend: What? How'd you manage that one?
Zuckerberg: People just submitted it.
Zuckerberg: I don't know why.
Zuckerberg: They "trust me"
Zuckerberg: Dumb fucks.'

But the article also reminds us that in Facebook's early days, "Zuckerberg listed 'revolutions' among his interests." The main dangers of authoritarian technocracy are not at this point political, at least not in the traditional sense. Still, a select few already have authoritarian control, more or less, to establish the digital world's rules and cultural norms, which can be as potent as political power...

[I]n recent years, it has become clear that regulation is needed, not least because the rise of technocracy proves that Silicon Valley's leaders simply will not act in the public's best interest. Much should be done to protect children from the hazards of social media, and to break up monopolies and oligopolies that damage society, and more. At the same time, I believe that regulation alone will not be enough to meaningfully address the cultural rot that the new technocrats are spreading.... We do not have to live in the world the new technocrats are designing for us. We do not have to acquiesce to their growing project of dehumanization and data mining. Each of us has agency.

No more "build it because we can." No more algorithmic feedbags. No more infrastructure designed to make the people less powerful and the powerful more controlling. Every day we vote with our attention; it is precious, and desperately wanted by those who will use it against us for their own profit and political goals. Don't let them.
  • The article specifically recommends "challenging existing norms about the use of apps and YouTube in classrooms, the ubiquity of smartphones in adolescent hands, and widespread disregard for individual privacy. People who believe that we all deserve better will need to step up to lead such efforts."
  • "Universities should reclaim their proper standing as leaders in developing world-changing technologies for the good of humankind. (Harvard, Stanford, and MIT could invest in creating a consortium for such an effort — their endowments are worth roughly $110 billion combined.)"

Threads is Now 'Booming', With 130 Million Active Users (techcrunch.com) 52

The Verge reports that Threads is "booming," according to figures shared by Mark Zuckerberg on Meta's earnings call, with 130 million active users a month.

TechCrunch reports: Threads is continuing to grow, having tripled its downloads month-over-month in December, which gave it a place in the top 10 most downloaded apps for the month across both the App Store and Google Play...

Threads famously had a record-breaking launch, reaching 100 million registered users within its first five days. However, the app saw its daily downloads decline starting last September through the end of the year. But in December, Threads once again returned to growth, likely due to the push Meta had given the app by displaying promos on Facebook that featured Threads' viral posts. Today, there are an estimated 160 million Threads users, according to one tracker...

The app could also be benefiting from its move into the "fediverse" — the social network comprised of interconnected servers that communicate via the ActivityPub protocol, like Mastodon... In addition, Threads recently announced the launch of an endpoint, allowing developers of third-party apps and websites to use a dynamic URL to refill text into the Threads composer. For example, there's now a website where anyone can generate Threads share links and profile badges. Marketing tool provider Shareaholic also just launched Threads Share buttons for websites, including both desktop and mobile sites. This flurry of activity around Threads is helping to move the app up in the chart rankings, though some inorganic boosts from Meta itself are likely also responsible for the jump in downloads, given the size.

Ask Slashdot: Can You Roll Your Own Home Router? 150

"My goal is to have a firewall that I trust," writes Slashdot reader eggegick, "not a firewall that comes from the manufacture that might have back doors." I'm looking for a cheap mini PC I can turn into a headless Linux-based wireless and Ethernet router. The setup would be a cable modem on the Comcast side, Ethernet out from the modem to the router and Ethernet, and WiFi out to the home network.
Two long-time Slashdot readers had suggestions. johnnys believes "any old desktop or even a laptop will work.... as long as you have a way to get a couple of (fast or Gigabit) Ethernet ports and a good WiFi adapter... " Cable or any consumer-grade broadband doesn't need exotic levels of throughput: Gigabit Ethernet will not be saturated by any such connection...

You can also look at putting FOSS firewall software like DD-WRT or OpenWrt on consumer-grade "routers". Such hardware is usually set up with the right hardware and capabilities you are looking for. Note however that newer hardware may not work with such firmwares as the FCC rules about controlling RF have caused many manufacturers to lock down firmware images.

And you don't necessarily need to roll your own with iptables: There are several BSD or Linux-based FOSS distributions that do good firewall functionality. PFSense is very good and user-friendly, and there are others. OpenBSD provides an exceptionally capable enterprise-level firewall on a secure platform, but it's not designed to be user-friendly.

Long-time Slashdot reader Spazmania agrees the "best bet" is "one of those generic home wifi routers that are supported by DD-WRT or OpenWrt." It's not uncommon to find something used for $10-$20. And then install one or the other, giving a Linux box with full control. Add a USB stick so you have enough space for all the utilities.

I just went through the search for mini-PCs for a project at work. The main problem is that almost all of them cool poorly, and that significantly impairs their life span.I finally found a few at the $100 price point that cooled acceptably... and they disappeared from the market shortly after I bought the test units, replaced with newer models in the $250 ballpark.

Mistral Confirms New Open Source AI Model Nearing GPT-4 Performance (venturebeat.com) 18

An anonymous reader quotes a report from VentureBeat: The past few days have been a wild ride for the growing open source AI community -- even by its fast-moving and freewheeling standards. Here's the quick chronology: on or about January 28, a user with the handle "Miqu Dev" posted a set of files on HuggingFace, the leading open source AI model and code sharing platform, that together comprised a seemingly new open source large language model (LLM) labeled "miqu-1-70b." The HuggingFace entry, which is still up at the time of this article's posting, noted that new LLM's "Prompt format," how users interact with it, was the same as Mistral, the well-funded open source Parisian AI company behind Mixtral 8x7b, viewed by many to be the top performing open source LLM presently available, a fine-tuned and retrained version of Meta's Llama 2.

The same day, an anonymous user on 4chan (possibly "Miqu Dev") posted a link to the miqu-1-70b files on 4chan, the notoriously longstanding haven of online memes and toxicity, where users began to notice it. Some took to X, Elon Musk's social network formerly known as Twitter, to share the discovery of the model and what appeared to be its exceptionally high performance at common LLM tasks (measured by tests known as benchmarks), approaching the previous leader, OpenAI's GPT-4 on the EQ-Bench. Machine learning (ML) researchers took notice on LinkedIn, as well. "Does 'miqu' stand for MIstral QUantized? We don't know for sure, but this quickly became one of, if not the best open-source LLM," wrote Maxime Labonne, an ML scientist at JP Morgan & Chase, one of the world's largest banking and financial companies. "Thanks to @152334H, we also now have a good unquantized version of miqu here: https://lnkd.in/g8XzhGSM. Quantization in ML refers to a technique used to make it possible to run certain AI models on less powerful computers and chips by replacing specific long numeric sequences in a model's architecture with shorter ones. Users speculated "Miqu" might be a new Mistral model being covertly "leaked" by the company itself into the world -- especially since Mistral is known for dropping new models and updates without fanfare through esoteric and technical means -- or perhaps an employee or customer gone rouge.

Well, today it appears we finally have confirmation of the latter of those possibilities: Mistral co-founder and CEO Arthur Mensch took to X to clarify: "An over-enthusiastic employee of one of our early access customers leaked a quantized (and watermarked) version of an old model we trained and distributed quite openly... To quickly start working with a few selected customers, we retrained this model from Llama 2 the minute we got access to our entire cluster -- the pretraining finished on the day of Mistral 7B release. We've made good progress since -- stay tuned!" Hilariously, Mensch also appears to have taken to the illicit HuggingFace post not to demand a takedown, but leaving a comment that the poster "might consider attribution." Still, with Mensch's note to "stay tuned!" it appears that not only is Mistral training a version of this so-called "Miqu" model that approaches GPT-4 level performance, but it may, in fact, match or exceed it, if his comments are to be interpreted generously.

Comcast Reluctantly Agrees To Stop Its Misleading '10G Network' Claims (arstechnica.com) 67

An anonymous reader quotes a report from Ars Technica: Comcast has reluctantly agreed to discontinue its "Xfinity 10G Network" brand name after losing an appeal of a ruling that found the marketing term was misleading. It will keep using the term 10G in other ways, however. Verizon and T-Mobile both challenged Comcast's advertising of 10G, a term used by cable companies since it was unveiled in January 2019 by industry lobby group NCTA-The Internet & Television Association. We wrote in 2019 that the cable industry's 10G marketing was likely to confuse consumers and seemed to be a way of countering 5G hype generated by wireless companies.

10G doesn't refer to the 10th generation of a technology. It is a reference to potential 10Gbps broadband connections, which would be much faster than the actual speeds on standard cable networks today. The challenges lodged against Comcast marketing were filed with the advertising industry's self-regulatory system run by BBB National Programs. BBB's National Advertising Division (NAD) ruled against Comcast in October 2023, but Comcast appealed to the National Advertising Review Board (NARB). The NARB announced its ruling today, agreeing with the NAD that "Comcast should discontinue use of the term 10G, both when used in the name of the service itself ('Xfinity 10G Network') as well as when used to describe the Xfinity network. The use of 10G in a manner that is not false or misleading and is consistent with the panel decision is not precluded by the panel recommendations."

Comcast agreed to make the change in an advertiser's statement that it provided to the NARB. "Although Comcast strongly disagrees with NARB's analysis and approach, Comcast will discontinue use of the brand name 'Xfinity 10G Network' and will not use the term '10G' in a manner that misleadingly describes the Xfinity network itself," Comcast said. Comcast said it disagrees with "the recommendation to discontinue the brand name" because the company "makes available 10Gbps of Internet speed to 98 percent of its subscribers upon request." But those 10Gbps speeds aren't available in Comcast's typical service plans and require a fiber-to-the-home connection instead of a standard cable installation. Comcast said it may still use 10G in ways that are less likely to confuse consumers. "Consistent with the panel's recommendation... Comcast reserves the right to use the term '10G' or 'Xfinity 10G' in a manner that does not misleadingly describe the Xfinity network itself," the company said.

Starlink's Laser System Is Beaming 42 Million GB of Data Per Day (pcmag.com) 97

SpaceX revealed that it's delivering over 42 petabytes of data for customers per day, according to engineer Travis Brashears. "We're passing over terabits per second [of data] every day across 9,000 lasers," Brashears said today at SPIE Photonics West, an event in San Francisco focused on the latest advancements in optics and light. "We actually serve over lasers all of our users on Starlink at a given time in like a two-hour window." PCMag reports: Although Starlink uses radio waves to beam high-speed internet to customers, SpaceX has also been outfitting the company's satellites with a "laser link" system to help drive down latency and improve the system's global coverage. The lasers, which can sustain a 100Gbps connection per link, are especially crucial to helping the satellites fetch data when no SpaceX ground station is near, like over the ocean or Antarctic. Instead, the satellite can transmit the data to and from another Starlink satellite in Earth's orbit, forming a mesh network in space.

Tuesday's talk from Brashears revealed the laser system is quite robust, even as the equipment is flying onboard thousands of Starlink satellites constantly circling the Earth. Despite the technical challenges, the company has achieved a laser "link uptime" at over 99%. The satellites are constantly forming laser links, resulting in about 266,141 "laser acquisitions" per day, according to Brashears' presentation. But in some cases, the links can also be maintained for weeks at a time, and even reach transmission rates at up to 200Gbps.

Brashears also said Starlink's laser system was able to connect two satellites over 5,400 kilometers (3,355 miles) apart. The link was so long "it cut down through the atmosphere, all the way down to 30 kilometers above the surface of the Earth," he said, before the connection broke. "Another really fun fact is that we held a link all the way down to 122 kilometers while we were de-orbiting a satellite," he said. "And we were able to downstream the video." During his presentation, Brashears also showed a slide depicting how the laser system can deliver data to a Starlink dish in Antarctica through about seven different paths. "We can dynamically change those routes within milliseconds. So as long as we have some path to the ground [station], you're going to have 99.99% uptime. That's why it's important to get as many nodes up there as possible," he added.

US Disabled Chinese Hacking Network Targeting Critical Infrastructure (reuters.com) 24

The U.S. government in recent months launched an operation to fight a pervasive Chinese hacking operation that successfully compromised thousands of internet-connected devices, Reuters reported Tuesday, citing two Western security officials and another person familiar with the matter. From the report: The Justice Department and Federal Bureau of Investigation sought and received legal authorization to remotely disable aspects of the Chinese hacking campaign, the sources told Reuters. The Biden administration has increasingly focused on hacking, not only for fear nation states may try to disrupt the U.S. election in November, but because ransomware wreaked havoc on Corporate America in 2023.

The hacking group at the center of recent activity, Volt Typhoon, has especially alarmed intelligence officials who say it is part of a larger effort to compromise Western critical infrastructure, including naval ports, internet service providers and utilities. While the Volt Typhoon campaign initially came to light in May 2023, the hackers expanded the scope of their operations late last year and changed some of their techniques, according to three people familiar with the matter. The widespread nature of the hacks led to a series of meetings between the White House and private technology industry, including several telecommunications and cloud commuting companies, where the U.S. government asked for assistance in tracking the activity.

T-Mobile Says It May Slow Home Internet Speeds of Some Users in Times of 'Congestion' (cnet.com) 72

T-Mobile has tweaked its terms of service for its home broadband users to add a new clause: If you are a heavy internet user that passes 1.2TB of data in a monthly billing cycle, you may have your speeds slowed in "times of congestion" or when there is a lot of pressure on the network. CNET: As spotted by The Mobile Report, the change went into effect on Jan. 18. In its updated terms, the carrier says that these users "will be prioritized last on the network" in congestion situations, which could mean painfully slow speeds for however long the congestion persists. T-Mobile does note that since its Home Internet service is available only in "limited areas" and intended to be used in a "stationary" setting, as opposed to a phone that could be in a busy place like a packed stadium, "these customers should be less likely to notice congestion in general."

America's Car Industry Seeks to Crush AM Radio. Will Congress Rescue It? (msn.com) 262

The Wall Street Journal reports that "a motley crew of AM radio advocates," including conservative talk show hosts and federal emergency officials, are lobbying Congress to stop carmakers from dropping AM radio from new vehicles: Lawmakers say most car companies are noncommittal about the future of AM tuners in vehicles, so they want to require them by law to keep making cars with free AM radio. Supporters argue it is a critical piece of the emergency communication network, while the automakers say Americans have plenty of other ways, including their phones, to receive alerts and information. The legislation has united lawmakers who ordinarily want nothing to do with one another. Sens. Ted Cruz (R., Texas) and Ed Markey (D., Mass.) are leading the Senate effort, and on the House side, Speaker Mike Johnson — himself a former conservative talk radio host in Louisiana — and progressive "squad" member Rep. Rashida Tlaib of Michigan are among about 200 co-sponsors...

A spring 2023 Nielsen survey, the most recent one available, showed that AM radio reaches about 78 million Americans every month. That is down from nearly 107 million in the spring of 2016, one of the earliest periods for which Nielsen has data... Automakers say the rise of electric vehicles is driving the shift away from AM, because onboard electronics create interference with AM radio signals — a phenomenon that "makes the already fuzzy analog AM radio frequency basically unlistenable," according to the Alliance for Automotive Innovation, a car-industry trade group. Shielding cables and components to reduce interference would cost carmakers $3.8 billion over seven years, the group estimates.

Markey and other lawmakers say they want to preserve AM radio because of its role in emergency communications. The Federal Emergency Management Agency says that more than 75 radio stations, most of which operate on the AM band and cover at least 90% of the U.S. population, are equipped with backup communications equipment and generators that allow them to continue broadcasting information to the public during and after an emergency. Seven former FEMA administrators urged Congress in a letter last year to seek assurances from automakers that they would keep broadcast radio available. The companies' noncommittal response spurred legislation, lawmakers said.

Automakers increasingly want to put radio and other car features "behind a paywall," Markey said in an interview. "They see this as another profit center for them when the American driving public has seen it as a safety resource for them and their families...." He compared the auto industry's resistance to the bill to previous opposition to government mandates like seat belts and air bags. "Leaving safety decisions to the auto industry is very dangerous," Markey said.

Lawmakers have heard from over 400,000 AM radio supporters, according to the president of the National Association of Broadcasters.

But the article also cites an executive at the Consumer Technology Association, who says automakers and tech advocacy groups have told lawmakers that requiring AM radio "would be "inconsistent with the principles of a free market.... It's strange that Congress is focused on a 100-year-old technology."

18-Year-Old Cleared After Encrypted Snapchat Joke Led To F-18s and Arrest (bbc.co.uk) 133

Slashdot reader Bruce66423 shared this report from the BBC: A Spanish court has cleared a British man of public disorder, after he joked to friends about blowing up a flight from London Gatwick to Menorca.

Aditya Verma admitted he told friends in July 2022: "On my way to blow up the plane. I'm a member of the Taliban." But he said he had made the joke in a private Snapchat group and never intended to "cause public distress"... The message he sent to friends, before boarding the plane, went on to be picked up by UK security services. They then flagged it to Spanish authorities while the easyJet plane was still in the air.

Two Spanish F-18 fighter jets were sent to flank the aircraft. One followed the plane until it landed at Menorca, where the plane was searched. Mr Verma, who was 18 at the time, was arrested and held in a Spanish police cell for two days. He was later released on bail... If he had been found guilty, the university student faced a fine of up to €22,500 (£19,300 or $20,967) and a further €95,000 (£81,204 or $103,200) in expenses to cover the cost of the jets being scrambled.

But how did his message first get from the encrypted app to the UK security services? One theory, raised in the trial, was that it could have been intercepted via Gatwick's Wi-Fi network. But a spokesperson for the airport told BBC News that its network "does not have that capability"... A spokesperson for Snapchat said the social media platform would not "comment on what's happened in this individual case".
richi (Slashdot reader #74,551) thinks it's obvious what happened: SnapChat's own web site says they scan messages for threats and passes them on to the authorities. ("We also work to proactively escalate to law enforcement any content appearing to involve imminent threats to life, such as...bomb threats...."

"In the case of emergency disclosure requests from law enforcement, our 24/7 team usually responds within 30 minutes."

Google and AT&T Invest In AST SpaceMobile For Satellite-To-Smartphone Service (fiercewireless.com) 18

AT&T, Google and Vodafone are investing a total of $206.5 million in AST SpaceMobile, a satellite manufacturer that plans to be the first space-based network to connect standard mobile phones at broadband speeds. Fierce Wireless reports: AST SpaceMobile claims it invented the space-based direct-to-device market, with a patented design facilitating broadband connectivity directly to standard, unmodified cellular devices. In a press release, AST SpaceMobile said the investment from the likes of AT&T, Google and Vodafone underscores confidence in the company's technology and leadership position in the emerging space-based cellular D2D market. There's the potential to offer connectivity to 5.5 billion cellular devices when they're out of coverage.

Bolstering the case for AST SpaceMobile, Vodafone and AT&T placed purchase orders -- for an undisclosed amount -- for network equipment to support their planned commercial services. In addition, Google and AST SpaceMobile agreed to collaborate on product development, testing and implementation plans for SpaceMobile network connectivity on Android and related devices. AST SpaceMobile boasts agreements and understandings with more than 40 mobile network operators globally. However, it's far from alone in the D2D space. Apple/Globalstar, T-Mobile/SpaceX, Bullitt and Lynk Global are among the others.

HP CEO Evokes James Bond-Style Hack Via Ink Cartridges (arstechnica.com) 166

An anonymous reader quotes a report from Ars Technica: Last Thursday, HP CEO Enrique Lores addressed the company's controversial practice of bricking printers when users load them with third-party ink. Speaking to CNBC Television, he said, "We have seen that you can embed viruses in the cartridges. Through the cartridge, [the virus can] go to the printer, [and then] from the printer, go to the network." That frightening scenario could help explain why HP, which was hit this month with another lawsuit over its Dynamic Security system, insists on deploying it to printers.

Dynamic Security stops HP printers from functioning if an ink cartridge without an HP chip or HP electronic circuitry is installed. HP has issued firmware updates that block printers with such ink cartridges from printing, leading to the above lawsuit (PDF), which is seeking class-action certification. The suit alleges that HP printer customers were not made aware that printer firmware updates issued in late 2022 and early 2023 could result in printer features not working. The lawsuit seeks monetary damages and an injunction preventing HP from issuing printer updates that block ink cartridges without an HP chip. [...]

Unsurprisingly, Lores' claim comes from HP-backed research. The company's bug bounty program tasked researchers from Bugcrowd with determining if it's possible to use an ink cartridge as a cyberthreat. HP argued that ink cartridge microcontroller chips, which are used to communicate with the printer, could be an entryway for attacks. [...] It's clear that HP's tactics are meant to coax HP printer owners into committing to HP ink, which helps the company drive recurring revenue and makes up for money lost when the printers are sold. Lores confirmed in his interview that HP loses money when it sells a printer and makes money through supplies. But HP's ambitions don't end there. It envisions a world where all of its printer customers also subscribe to an HP program offering ink and other printer-related services. "Our long-term objective is to make printing a subscription. This is really what we have been driving," Lores said.

How a Data Breach of 1M Cancer Center Patients Led to Extorting Emails (seattletimes.com) 37

The Seattle Times reports: Concerns have grown in recent weeks about data privacy and the ongoing impacts of a recent Fred Hutchinson Cancer Center cyberattack that leaked personal information of about 1 million patients last November. Since the breach, which hit the South Lake Union cancer research center's clinical network and has led to a host of email threats from hackers and lawsuits against Fred Hutch, menacing messages from perpetrators have escalated.

Some patients have started to receive "swatting" threats, in addition to spam emails warning people that unless they pay a fee, their names, Social Security and phone numbers, medical history, lab results and insurance history will be sold to data brokers and on black markets. Steve Bernd, a spokesperson for FBI Seattle, said last week there's been no indication of any criminal swatting events... Other patients have been inundated with spam emails since the breach...

According to The New York Times, large data breaches like this are becoming more common. In the first 10 months of 2023, more than 88 million individuals had their medical data exposed, according to the Department of Health and Human Services. Meanwhile, the number of reported ransomware incidents, when a specific malware blocks a victim's personal data until a ransom is paid, has decreased in recent years — from 516 in 2021 to 423 in 2023, according to Bernd of FBI Seattle. In Washington, the number dropped from 84 to 54 in the past three years, according to FBI data.

Fred Hutchinson Cancer Center believes their breach was perpetrated outside the U.S. by exploiting the "Citrix Bleed" vulnerability (which federal cybersecurity officials warn can allow the bypassing of passwords and mutifactor authentication measures).

The article adds that in late November, the Department of Health and Human Services' Health Sector Cybersecurity Coordination Center "urged hospitals and other organizations that used Citrix to take immediate action to patch network systems in order to protect against potentially significant ransomware threats."

Nearby Galaxy's Giant Black Hole Is Real, 'Shadow' Image Confirms (science.org) 30

"A familiar shadow looms in a fresh image of the heart of the nearby galaxy M87," reports Science magazine.

"It confirms that the galaxy harbors a gravitational sinkhole so powerful that light cannot escape, one generated by a black hole 6.5 billion times the mass of the Sun." But compared with a previous image from the network of radio dishes called the Event Horizon Telescope (EHT), the new one reveals a subtle shift in the bright ring surrounding the shadow, which could provide clues to how gases churn around the black hole. "We can see that shift now," says team member Sera Markoff of the University of Amsterdam. "We can start to use that." The new detail has also whetted astronomers' desire for a proposed expansion of the EHT, which would deliver even sharper images of distant black holes.

The new picture, published this week in Astronomy & Astrophysics, comes from data collected 1 year after the observing campaign that led to the first-ever picture of a black hole, revealed in 2019 and named as Science's Breakthrough of the Year. The dark center of the image is the same size as in the original image, confirming that the image depicts physical reality and is not an artifact. "It tells us it wasn't a fluke," says Martin Hardcastle, an astrophysicist at the University of Hertfordshire who was not involved in the study. The black hole's mass would not have grown appreciably in 1 year, so the comparison also supports the idea that a black hole's size is determined by its mass alone. In the new image, however, the brightest part of a ring surrounding the black hole has shifted counterclockwise by about 30 degrees.

That could be because of random churning in the disk of material that swirls around the black hole's equator. It could also be associated with fluctuations in one of the jets launched from the black hole's poles — a sign that the jet isn't aligned with the black hole's spin axis, but precesses around it like a wobbling top. That would be "kind of exciting," Markoff says. "The only way to know is to keep taking pictures...."

[T]he team wants to add more telescopes to the network, which would further sharpen its images and enable it to see black holes in more distant galaxies.

Ceph: a Journey To 1 TiB/s (ceph.io) 16

It's "a free and open-source, software-defined storage platform," according to Wikipedia, providing object storage, block storage, and file storage "built on a common distributed cluster foundation". The charter advisory board for Ceph included people from Canonical, CERN, Cisco, Fujitsu, Intel, Red Hat, SanDisk, and SUSE.

And Nite_Hawk (Slashdot reader #1,304) is one of its core engineers — a former Red Hat principal software engineer named Mark Nelson. (He's now leading R&D for a small cloud systems company called Clyso that provides Ceph consulting.) And he's returned to Slashdot to share a blog post describing "a journey to 1 TiB/s". This gnarly tale-from-Production starts while assisting Clyso with "a fairly hip and cutting edge company that wanted to transition their HDD-backed Ceph cluster to a 10 petabyte NVMe deployment" using object-based storage devices [or OSDs]...) I can't believe they figured it out first. That was the thought going through my head back in mid-December after several weeks of 12-hour days debugging why this cluster was slow... Half-forgotten superstitions from the 90s about appeasing SCSI gods flitted through my consciousness...

Ultimately they decided to go with a Dell architecture we designed, which quoted at roughly 13% cheaper than the original configuration despite having several key advantages. The new configuration has less memory per OSD (still comfortably 12GiB each), but faster memory throughput. It also provides more aggregate CPU resources, significantly more aggregate network throughput, a simpler single-socket configuration, and utilizes the newest generation of AMD processors and DDR5 RAM. By employing smaller nodes, we halved the impact of a node failure on cluster recovery....

The initial single-OSD test looked fantastic for large reads and writes and showed nearly the same throughput we saw when running FIO tests directly against the drives. As soon as we ran the 8-OSD test, however, we observed a performance drop. Subsequent single-OSD tests continued to perform poorly until several hours later when they recovered. So long as a multi-OSD test was not introduced, performance remained high. Confusingly, we were unable to invoke the same behavior when running FIO tests directly against the drives. Just as confusing, we saw that during the 8 OSD test, a single OSD would use significantly more CPU than the others. A wallclock profile of the OSD under load showed significant time spent in io_submit, which is what we typically see when the kernel starts blocking because a drive's queue becomes full...

For over a week, we looked at everything from bios settings, NVMe multipath, low-level NVMe debugging, changing kernel/Ubuntu versions, and checking every single kernel, OS, and Ceph setting we could think of. None these things fully resolved the issue. We even performed blktrace and iowatcher analysis during "good" and "bad" single OSD tests, and could directly observe the slow IO completion behavior. At this point, we started getting the hardware vendors involved. Ultimately it turned out to be unnecessary. There was one minor, and two major fixes that got things back on track.

It's a long blog post, but here's where it ends up:
  • Fix One: "Ceph is incredibly sensitive to latency introduced by CPU c-state transitions. A quick check of the bios on these nodes showed that they weren't running in maximum performance mode which disables c-states."
  • Fix Two: [A very clever engineer working for the customer] "ran a perf profile during a bad run and made a very astute discovery: A huge amount of time is spent in the kernel contending on a spin lock while updating the IOMMU mappings. He disabled IOMMU in the kernel and immediately saw a huge increase in performance during the 8-node tests." In a comment below, Nelson adds that "We've never seen the IOMMU issue before with Ceph... I'm hoping we can work with the vendors to understand better what's going on and get it fixed without having to completely disable IOMMU."
  • Fix Three: "We were not, in fact, building RocksDB with the correct compile flags... It turns out that Canonical fixed this for their own builds as did Gentoo after seeing the note I wrote in do_cmake.sh over 6 years ago... With the issue understood, we built custom 17.2.7 packages with a fix in place. Compaction time dropped by around 3X and 4K random write performance doubled."

The story has a happy ending, with performance testing eventually showing data being read at 635 GiB/s — and a colleague daring them to attempt 1 TiB/s. They built a new testing configuration targeting 63 nodes — achieving 950GiB/s — then tried some more performance optimizations...

OpenAI Ceo Sam Altman Is Still Chasing Billions To Build AI Chips 11

According to Bloomberg (paywalled), OpenAI CEO Sam Altman is reportedly raising billions to develop a global network of chip fabrication factories, collaborating with leading chip manufacturers to address the high demand for chips required for advanced AI models. The Verge reports: A major cost and limitation for running AI models is having enough chips to handle the computations behind bots like ChatGPT or DALL-E that answer prompts and generate images. Nvidia's value rose above $1 trillion for the first time last year, partly due to a virtual monopoly it has as GPT-4, Gemini, Llama 2, and other models depend heavily on its popular H100 GPUs.

Accordingly, the race to manufacture more high-powered chips to run complex AI systems has only intensified. The limited number of fabs capable of making high-end chips is driving Altman or anyone else to bid for capacity years before you need it in order to produce the new chips. And going against the likes of Apple requires deep-pocketed investors who will front costs that the nonprofit OpenAI still can't afford. SoftBank Group and Abu Dhabi-based AI holding company G42 have reportedly been in talks about raising money for Altman's project.

Why Every Coffee Shop Looks the Same (theguardian.com) 67

An anonymous reader shares a report: These cafes had all adopted similar aesthetics and offered similar menus, but they hadn't been forced to do so by a corporate parent, the way a chain like Starbucks replicated itself. Instead, despite their vast geographical separation and total independence from each other, the cafes had all drifted toward the same end point. The sheer expanse of sameness was too shocking and new to be boring. Of course, there have been examples of such cultural globalisation going back as far as recorded civilisation. But the 21st-century generic cafes were remarkable in the specificity of their matching details, as well as the sense that each had emerged organically from its location. They were proud local efforts that were often described as "authentic," an adjective that I was also guilty of overusing. When travelling, I always wanted to find somewhere "authentic" to have a drink or eat a meal.

If these places were all so similar, though, what were they authentic to, exactly? What I concluded was that they were all authentically connected to the new network of digital geography, wired together in real time by social networks. They were authentic to the internet, particularly the 2010s internet of algorithmic feeds. In 2016, I wrote an essay titled Welcome to AirSpace, describing my first impressions of this phenomenon of sameness. "AirSpace" was my coinage for the strangely frictionless geography created by digital platforms, in which you could move between places without straying beyond the boundaries of an app, or leaving the bubble of the generic aesthetic. The word was partly a riff on Airbnb, but it was also inspired by the sense of vaporousness and unreality that these places gave me. They seemed so disconnected from geography that they could float away and land anywhere else. When you were in one, you could be anywhere.

My theory was that all the physical places interconnected by apps had a way of resembling one another. In the case of the cafes, the growth of Instagram gave international cafe owners and baristas a way to follow one another in real time and gradually, via algorithmic recommendations, begin consuming the same kinds of content. One cafe owner's personal taste would drift toward what the rest of them liked, too, eventually coalescing. On the customer side, Yelp, Foursquare and Google Maps drove people like me -- who could also follow the popular coffee aesthetics on Instagram -- toward cafes that conformed with what they wanted to see by putting them at the top of searches or highlighting them on a map. To court the large demographic of customers moulded by the internet, more cafes adopted the aesthetics that already dominated on the platforms. Adapting to the norm wasn't just following trends but making a business decision, one that the consumers rewarded. When a cafe was visually pleasing enough, customers felt encouraged to post it on their own Instagram in turn as a lifestyle brag, which provided free social media advertising and attracted new customers. Thus the cycle of aesthetic optimisation and homogenisation continued.
