A Linux Foundation project focused on understanding the health of the open source community just studied the outcomes for three projects that switched to "more restrictive" licenses and then faced community forks.

The data science director for the project — known as Community Health Analytics in Open Source Software (or CHAOSS) — is also an OpenUK board member, and describes the outcomes for OpenSearch, Redis with fork Valkey, and Terraform: The relicensed project (Redis) had significant numbers of contributors who were not employed by the company, and the fork (Valkey) was created by those existing contributors as a foundation project... The Redis project differs from Elasticsearch and Terraform in the number of contributions to the Redis repository from people who were not employees of Redis. In the year leading up to the relicense, when Redis was still open source, there were substantial contributions from employees of other companies: Twice as many non-Redis employees made five or more commits, and about a dozen employees of other companies made almost twice as many commits as Redis employees made.

In the six months after the relicense, all of the external contributors from companies (including Amazon, Alibaba, Tencent, Huawei and Ericsson) who contributed over five commits to the Redis project in the year prior to the relicense stopped contributing. In sum, Redis had strong organizational diversity before the relicense, but only Redis employees made significant contributions afterward.

Valkey was forked from Redis 7.2.4 on March 28, 2024, as a Linux Foundation project under the BSD-3 license. The fork was driven by a group of people who previously contributed to Redis with public support from their employers. Within its first six months, the Valkey repository had 29 contributors employed at 10 companies, and 18 of those people previously contributed to Redis. Valkey has a diverse set of contributors from various companies, with Amazon having the most contributors.
The results weren't always so clear-cut. Because Terraform always had very few contributors outside of the company, "there was no substantial impact on the contributor community from the relicensing event..." (Although the OpenTofu fork — a Linux Foundation project — had 31 people at 11 organizations who made five or more contributions.)

And both before and after Elasticsearch's relicensing, most contributors were Elastic employees, so "the 2021 relicense had little to no impact on contributors." (But the OpenSearch fork — transferred in September to the Linux Foundation — shows a more varied contributor base, with just 63% of additions and 64% of deletions coming from Amazon employees who made 10 or more commits. Six people who didn't work for Amazon made 10 or more commits, making up 11% of additions and 13% of deletions.")

So "Looking at all of these projects together, we see that the forks from relicensed projects tend to have more organizational diversity than the original projects," they conclude, adding that in general "projects with greater organizational diversity tend to be more sustainable..."

"You can dive into the details about these six projects in the paper, presentation and data we shared at the recent OpenForum Academy Symposium.

A new report reveals that the VW Group left sensitive data for 800,000 electric vehicles from Audi, VW, Seat, and Skoda poorly secured on an Amazon cloud, exposing precise GPS locations, battery statuses, and user habits for months. Carscoops reports: It gets worse. A more tech-savvy user could reportedly connect vehicles to their owners' personal credentials, thanks to additional data accessible through VW Group's online services Crucially, in 466,000 of the 800,000 cases, the location data was so precise that anyone with access could create a detailed profile of each owner's daily habits. As reported by Spiegel, the massive list of affected owners isn't just a who's-who of regular folks. It includes German politicians, entrepreneurs, Hamburg police officers (the entire EV fleet, no less), and even suspected intelligence service employees. Yes, even spies may have been caught up in this digital debacle.

This glaring error originated from Cariad, a VW Group company that focuses on software, due to an error that occurred in the summer of 2024. An anonymous whistleblower used freely accessible software to dig up the sensitive information and promptly alerted Chaos Computer Club (CCC), Europe's largest hacker association. CCC wasted no time contacting Lower Saxony's State Data Protection Officer, the Federal Ministry of the Interior, and other security bodies. They also gave VW Group and Cariad 30 days to address the issue before going public. According to CCC, Cariad's technical team "responded quickly, thoroughly and responsibly," blocking unauthorized access to its customers' data.

President Biden on Monday signed the SHARE IT Act (H.R. 9566) into law, mandating federal agencies share custom-developed code with each other to prevent duplicative software development contracts and reduce the $12 billion annual government software expenditure. The law requires agencies to publicly list metadata about custom code, establish sharing policies, and align development with best practices while exempting classified, national security, and privacy-sensitive code. FedScoop reports: Under the law, agency chief information officers are required to develop policies within 180 days of enactment that implement the act. Those policies need to ensure that custom-developed code aligns with best practices, establish a process for making the metadata for custom code publicly available, and outline a standardized reporting process. Per the new law, metadata includes information about whether custom code was developed under a contract or shared in a repository, the contract number, and a hyperlink to the repository where the code was shared. The legislation also has industry support. Stan Shepard, Atlassian's general counsel, said that the company shares "the belief that greater collaboration and sharing of custom code will promote openness, efficiency, and innovation across the federal enterprise."

The Federal Trade Commission has launched a broad antitrust investigation into Microsoft's business practices, focusing on how the company bundles its Office products with cybersecurity and cloud computing services.

The probe follows ProPublica reporting that revealed Microsoft offered free temporary upgrades of federal agencies' software licenses to include advanced cybersecurity features, leading to long-term contracts once the trial period ended. The strategy helped Microsoft expand its government business while displacing competitors in both cybersecurity and cloud computing markets.

The investigation includes scrutiny of Microsoft's identity management product Entra ID, formerly Azure Active Directory. The FTC has issued a civil investigative demand compelling the company to turn over information. The probe represents one of FTC Chair Lina Khan's final moves before leadership changes under the Biden administration. Microsoft confirmed receiving the demand but called it "broad, wide ranging, and requests things that are out of the realm of possibility to even be logical."

Apple's $3,499 Vision Pro headset has failed to gain widespread adoption despite advanced technology, with consumers preferring discreet wearables like smartwatches. The Verge: Nearly a year from launch, though, Apple hasn't done enough to demonstrate why the Vision Pro should be a potential showcase of the future of computing. It's taking a long time to put together its immersive content library, and while those are great demonstrations of what's possible, the videos have been short and isolating. There aren't many great games, either.

Yes, Apple keeps adding cool new software features. The wide and ultra widescreen settings for using a Mac display seem exceptionally useful. But those are pretty specific options for pretty specific use cases. There still isn't an immediate, obvious reason to buy a Vision Pro the way there usually is with the company's newest iPhones and Macs. If I bought a Vision Pro today, I wouldn't know what to do with it besides give myself a bigger Mac screen or watch movies, and I don't think either of those are worth the exorbitant price.

Microsoft has integrated its AI assistant Copilot into Microsoft 365 subscriptions in Australia and Southeast Asia, simultaneously raising prices for all users. The move forces customers to pay for AI features regardless of interest, prompting complaints about intrusive pop-ups and price hikes, WSJ reports. From the report: Some users said on social media that Copilot pop-ups reminded them of Clippy, Microsoft's widely derided Office helper from the late 1990s, that would frequently offer unsolicited help.

[...] The change demonstrates the lengths to which Microsoft is going to try to profit from its huge investments in AI. Copilot, which is built with technology from OpenAI, is a key part of Chief Executive Satya Nadella's plan to keep expanding Microsoft's software business for consumer and corporate customers.

An anonymous reader shares a report: Microsoft has published a year in review for its Edge browser and talked up AI-powered chats while lightly skipping over the software's stagnating market share. The company had some big numbers to share. There had been over 10 billion AI-powered chats with Copilot from inside the Edge browser window (although it did not disclose how many chats were customers asking how to install Chrome). Some 38 trillion characters had been auto-translated. Seven trillion megabytes of PC memory had been saved through the use of sleeping tabs.

However, are those numbers actually as big as they seem? What Microsoft did not say is how little Edge has moved the needle on market share in 2024. Strangely, the company did not share raw usage information. Yet, a look at Statcounter's figures for browser desktop market share showed Edge with 11.9 percent of the market in December 2023 and reaching 12.87 percent by November 2024 -- an increase of less than 1 percent. The market leader, Google's Chrome browser, went from 65.23 percent to 66.33 percent in the same period. That's only slightly more than 1 percent, but it still maintains its dominance.

Software development is entering an "autopilot era" with AI coding assistants, but the industry needs to prepare for full autonomy, argues former Salesforce co-CEO Bret Taylor. Drawing parallels with self-driving cars, he suggests the role of software engineers will evolve from code authors to operators of code-generating machines. Taylor, a board member of OpenAI and who once rewrote Google Maps over a weekend, calls for new programming systems, languages, and verification methods to ensure AI-generated code remains robust and secure. From his post: In the Autonomous Era of software engineering, the role of a software engineer will likely transform from being the author of computer code to being the operator of a code generating machine. What is a computer programming system built natively for that workflow?

If generating code is no longer a limiting factor, what types of programming languages should we build?

If a computer is generating most code, how do we make it easy for a software engineer to verify it does what they intend? What is the role of programming language design (e.g., what Rust did for memory safety)? What is the role of formal verification? What is the role of tests, CI/CD, and development workflows?

Today, a software engineer's primary desktop is their editor. What is the Mission Control for a software engineer in the era of autonomous development?

An anonymous reader quotes a report from Tom's Hardware: Although Samsung Foundry is a major chip contract manufacturer, the South Korean government mulls creating a government-funded contract chipmaker tentatively called Korea Semiconductor Manufacturing Company, KSMC, reports The Korea Biz Wire. Industry experts and academics have proposed the initiative.

The Semiconductor Industry Association's Ahn Ki-hyun called for a long-term government investment. Experts project that an investment of KRW 20 trillion ($13.9 billion) in KSMC could result in economic gains of KRW 300 trillion ($208.7 billion) by 2045. However, the big question is whether $13.9 billion is enough to establish a chipmaker. Another concern about publicly funded corporations like KSMC is whether they could develop advanced manufacturing technologies and land enough orders from clients to be profitable. It turns out that in addition to semiconductor makers, Korea needs more fabless software developers.

The proposal was introduced during a seminar hosted by the National Academy of Engineering of Korea (NAEK). The plan aims to address structural weaknesses in the industry, such as an over-reliance on Samsung's advanced nodes under 10nm amid the lack of mature process technologies. Smaller system semiconductor firms struggle to thrive as Korea lacks manufacturing diversity, as seen in Taiwan, where companies like UMC and PSMC that focus on mature and specialty nodes complement TSMC's advanced process technologies.

The UK Post Office has appointed Paul Anastassi as interim CTO amid efforts to replace its controversial Horizon IT system, which led to hundreds of wrongful convictions of subpostmasters due to software errors since 1999.

The appointment, the news of which an anonymous reader shared, comes as the Post Office grapples with its $1.25 billion over-budget New Branch IT project, which was recently paused after being deemed "unachievable" in a government report. The organization is reportedly considering purchasing the Horizon system from Fujitsu while combining it with in-house and commercial software solutions.

An anonymous reader shares a report: Over the past year, OpenAI has dropped not-so-subtle hints about its revived interest in robotics: investing in startups developing hardware and software for robots such as Figure and Physical Intelligence and rebooting its internal robotics software team, which it had disbanded four years ago.

Now, OpenAI could be taking that interest to the next level. The company has recently considered developing a humanoid robot, according to two people with direct knowledge of the discussions. As a refresher, humanoid robots typically have two arms and two legs, distinguishing them from typical robots in a warehouse or factory that might have a single arm repeatedly performing the same task on an assembly line. Developers of humanoid robots think it will be easier for them to handle tasks in the physical world -- which is tailored to humans -- than it would be to change our physical environments to suit new robots.

ASUS computer owners have been reporting widespread alarm after a Christmas-themed banner suddenly appeared on their Windows 11 screens, accompanied by a suspicious "Christmas.exe" process in Task Manager.

The promotional campaign, first reported by WindowsLatest, was delivered through ASUS' pre-installed Armoury Crate software. It displays a large wreath banner that covers one-third of users' screens. The unbranded holiday display, which can interrupt gaming sessions and occasionally crashes applications, has triggered security concerns among users who initially mistook it for malware.

Netflix has sued Broadcom in California federal court, accusing the chipmaker's cloud computing subsidiary VMware of violating its patent rights in virtual machines. From a report: The lawsuit said VMware's cloud software infringes five Netflix patents covering aspects of operating virtual machines. Broadcom and Netflix have been embroiled in a separate patent dispute since 2018 over Netflix's alleged infringement of Broadcom patents related to video streaming technology, with cases in California, Germany and the Netherlands.

Since 2021, Apple has been sending threat notifications to certain users, informing them that they may have been individually targeted by mercenary spyware attacks. When victims of spyware reach out to Apple for help, TechCrunch reports, "Apple doesn't tell the targets to get in touch with its own security engineers." Instead, Apple directs them to the nonprofit security lab Access Now, "which runs a digital helpline for people in civil society who suspect they have been targets of government spyware."

While some view this as Apple sidestepping responsibility, cybersecurity experts agree that Apple's approach -- alerting victims, directing them to specialized support, and recommending tools like Lockdown Mode -- has been a game changer in combating mercenary spyware threats. From the report: For people who investigate spyware, Apple sharing spyware notifications with victims represented a turning point. Before the notifications, "We were just like in the dark, not knowing who to check," according to Access Now's legal counsel Natalia Krapiva. "I think it's one of the greatest things that's happened in the sphere of this kind of forensic investigations and hunting of sophisticated spyware," Krapiva told TechCrunch.

Now, when someone or a group of people get a notification from Apple, they are warned that something potentially anomalous is happening with their device, that someone is targeting them, and that they need to get help. And Apple tells them exactly where to get it, according to Scott-Railton, who said Access Now's helpline is the right place to go because "the helpline is able to do good, systematic triage work and support." Krapiva said that the helpline is staffed by more than 30 people, supported by others who work in other departments of the nonprofit. So far in 2024, Krapiva said Access Now received 4,337 tickets through the helpline.

For anyone alerted by a notification, Apple tells those targets and victims of spyware to update their iOS software and all their apps. Apple also suggests the user switches on Lockdown Mode, an opt-in iOS security feature that has stopped spyware attacks in the past by limiting device features that are often exploited to plant spyware. Apple said last year that it is not aware of any successful spyware infection against someone who used Lockdown Mode.

An anonymous reader quotes a report from Gizmodo: Once an icon of the 20th century seen as obsolete in the 21st, Encyclopedia Britannica -- now known as just Britannica -- is all in on artificial intelligence, and may soon go public at a valuation of nearly $1 billion, according to the New York Times.

Until 2012 when printing ended, the company's books served as the oldest continuously published, English-language encyclopedias in the world, essentially collecting all the world's knowledge in one place before Google or Wikipedia were a thing. That has helped Britannica pivot into the AI age, where models benefit from access to high-quality, vetted information. More general-purpose models like ChatGPT suffer from hallucinations because they have hoovered up the entire internet, including all the junk and misinformation.

While it still offers an online edition of its encyclopedia, as well as the Merriam-Webster dictionary, Britannica's biggest business today is selling online education software to schools and libraries, the software it hopes to supercharge with AI. That could mean using AI to customize learning plans for individual students. The idea is that students will enjoy learning more when software can help them understand the gaps in their understanding of a topic and stay on it longer. Another education tech company, Brainly, recently announced that answers from its chatbot will link to the exact learning materials (i.e. textbooks) they reference.

Britannica's CEO Jorge Cauz also told the Times about the company's Britannica AI chatbot, which allows users to ask questions about its vast database of encyclopedic knowledge that it collected over two centuries from vetted academics and editors. The company similarly offers chatbot software for customer service use cases. Britannica told the Times it is expecting revenue to double from two years ago, to $100 million.

A U.S. judge has ruled that Israeli spyware maker NSO Group breached hacking laws by using WhatsApp to infect devices with its Pegasus spyware. From a report: In a historic ruling on Friday, a Northern California federal judge held NSO Group liable for targeting the devices of 1,400 WhatsApp users, violating state and federal hacking laws as well as WhatsApp's terms of service, which prohibit the use of the messaging platform for malicious purposes.

The ruling comes five years after Meta-owned WhatsApp sued NSO Group, alleging the spyware outfit had exploited an audio-calling vulnerability in the messaging platform to install its Pegasus spyware on unsuspecting users' devices. WhatsApp said that more than 100 human rights defenders, journalists and "other members of civil society" were targeted by the malware, along with government officials and diplomats. In her ruling, Judge Phyllis Hamilton said NSO did not dispute that it "must have reverse-engineered and/or decompiled the WhatsApp software" to install its Pegasus spyware on devices, but raised questions about whether it had done so before agreeing to WhatsApp's terms of service.

Silicon Valley is betting the farm on AI. Data centers are straining power grids. Model training costs are heading toward billions. Yet across the software industry, AI revenue remains theoretical. From a report: Hyperscalers -- combined with Meta and Oracle -- plan to spend $292 billion on AI infrastructure by 2025 -- an 88% increase since 2023. Two-thirds of software companies, however, still report decelerating growth in 2024.

Semiconductor stocks have surged 43% year-to-date on AI expectations, while the software index IGV is up 30%. Microsoft, despite its OpenAI investment, has underperformed the IGV by 19% since ChatGPT's release. Microsoft's AI revenue run rate is 3% of total revenue, according to estimates by investment bank Jefferies. Snowflake expects immaterial AI contribution in fiscal 2025. Salesforce isn't factoring in material contribution from new AI products into FY25 guidance. Adobe's Firefly AI, launched in March 2023, hasn't accelerated revenue.

A demonstration "race" between a (human) F1 race car driver Daniil Kvyat and an autonomous vehicle was just staged by the Abu Dhabi Autonomous Racing League.

Describing the league and the "man vs. machine" showdown, Ars Technica writes, "Say goodbye to the human driver and hello to 95 kilograms of computers and a whole suite of sensors." But again, racing is hard, and replacing humans doesn't change that. The people who run and participate in A2RL are aware of this, and while many organizations have made it a sport of overselling AI, A2RL is up-front about the limitations of the current state of the technology. One example of the technology's current shortcomings: The vehicles can't swerve back and forth to warm up the tires. Giovanni Pau, Team Principal of TII Racing, stated during a press briefing regarding the AI system built for racing, "We don't have human intuition. So basically, that is one of the main challenges to drive this type of car. It's impossible today to do a correct grip estimation. A thing my friend Daniil (Kvyat) can do in a nanosecond...."

Technology Innovation Institute (TII) develops the hardware and software stack for all the vehicles. Hardware-wise, the eight teams receive the same technology. When it comes to software, the teams need to build out their own system on TII's software stack to get the vehicles to navigate the tracks. In April, four teams raced on the track in Abu Dhabi. As we've noted before, how the vehicles navigate the tracks and world around them isn't actually AI. It's programmed responses to an environment; these vehicles are not learning on their own. Frankly, most of what is called "AI" in the real world is also not AI.

Vehicles driven by the systems still need years of research to come close to the effectiveness of a human beyond the wheel. Kvyat has been working with A2RL since the beginning. In that time, the former F1 driver has been helping engineers understand how to bring the vehicle closer to their limit. The speed continues to increase as the development progresses. Initially, the vehicles were three to five minutes slower than Kvyat around a lap; now, they are about eight seconds behind. That's a lifetime in a real human-to-human race, but an impressive amount of development for vehicles with 90 kg of computer hardware crammed into the cockpit of a super formula car. Currently, the vehicles are capable of recreating 90-95 percent of the speed of a human driver, according to Pau. Those capabilities are reduced when a human driver is also on the track, particularly for safety reasons....

The "race" was to be held ahead of the season finale of the Super Formula season... The A2RL vehicle took off approximately 22 seconds ahead of Kvyat, but the race ended before the practice lap was completed. Cameras missed the event, but the A2RL car lost traction and ended up tail-first into a wall...

Khurram Hassan, commercial director of A2RL, told Ars that the cold tires on the cold track caused a loss of traction.

"From the moment GPT-4 came out in March 2023, OpenAI has been working on GPT-5..." reports the Wall Street Journal. [Alternate URL here.] But "OpenAI's new artificial-intelligence project is behind schedule and running up huge bills. It isn't clear when — or if — it'll work."

"There may not be enough data in the world to make it smart enough." OpenAI's closest partner and largest investor, Microsoft, had expected to see the new model around mid-2024, say people with knowledge of the matter. OpenAI has conducted at least two large training runs, each of which entails months of crunching huge amounts of data, with the goal of making Orion smarter. Each time, new problems arose and the software fell short of the results researchers were hoping for, people close to the project say... [And each one costs around half a billion dollars in computing costs.]

The $157 billion valuation investors gave OpenAI in October is premised in large part on [CEO Sam] Altman's prediction that GPT-5 will represent a "significant leap forward" in all kinds of subjects and tasks.... It's up to company executives to decide whether the model is smart enough to be called GPT-5 based in large part on gut feelings or, as many technologists say, "vibes."

So far, the vibes are off...
OpenAI wants to use its new model to generate high-quality synthetic data for training, according to the article. But OpenAI's researchers also "concluded they needed more diverse, high-quality data," according to the article, since "The public internet didn't have enough, they felt." OpenAI's solution was to create data from scratch. It is hiring people to write fresh software code or solve math problems for Orion to learn from. [And also theoretical physics experts] The workers, some of whom are software engineers and mathematicians, also share explanations for their work with Orion... Having people explain their thinking deepens the value of the newly created data. It's more language for the LLM to absorb; it's also a map for how the model might solve similar problems in the future... The process is painfully slow. GPT-4 was trained on an estimated 13 trillion tokens. A thousand people writing 5,000 words a day would take months to produce a billion tokens.

OpenAI's already-difficult task has been complicated by internal turmoil and near-constant attempts by rivals to poach its top researchers, sometimes by offering them millions of dollars... More than two dozen key executives, researchers and longtime employees have left OpenAI this year, including co-founder and Chief Scientist Ilya Sutskever and Chief Technology Officer Mira Murati. This past Thursday, Alec Radford, a widely admired researcher who served as lead author on several of OpenAI's scientific papers, announced his departure after about eight years at the company...

OpenAI isn't the only company worrying that progress has hit a wall. Across the industry, a debate is raging over whether improvement in AIs is starting to plateau. Sutskever, who recently co-founded a new AI firm called Safe Superintelligence or SSI, declared at a recent AI conference that the age of maximum data is over. "Data is not growing because we have but one internet," he told a crowd of researchers, policy experts and scientists. "You can even go as far as to say that data is the fossil fuel of AI."

And that fuel was starting to run out.

"Voyager 1 is currently exploring interstellar space at a distance of 15.5 billion miles (24.9 billion kilometers) away from Earth," writes Gizmodo.

And yet a team of amateur astronomers in the Netherlands was able to receive Voyager's signals on a 1950s-era telescope... The astronomers used orbital predictions of Voyager 1's position in space to correct for the Doppler shift in frequency caused by the motion of Earth, as well as the motion of the spacecraft through space... [The signal] was found live, and further analysis later confirmed that it corresponded to the position of Voyager 1.
"I did the experiment," mathematician/scientific software engineer Tammo Jan Dijkema told Slashdot in an email, as "one of a crew of four." He works at ASTRON (the Netherlands Institute for Radio Astronomy) while volunteering at the Dwingeloo radio telescope, and wants to clarify any suggestion in Gizmodo's article "that we received signals at S-band, which is not true. We received the 'normal' Voyager-1 signal at 8.4 GHz. See our blog post... The Dwingeloo reception was not related to Voyager's temporary glitch at all."

And Scientific American shares an interesting perspective on the Voyager probes: we everyday Earthlings may simplistically think of the sun as a compact distant ball of light, in part because our plush atmosphere protects us from our star's worst hazards. But in reality the sun is a roiling mass of plasma and magnetism radiating itself across billions of miles in the form of the solar wind, which is a constant stream of charged plasma that flows off our star. The sun's magnetic field travels with the solar wind and also influences the space between planets. The heliosphere grows and shrinks in response to changes in the sun's activity levels over the course of an 11-year cycle... [Jamie Rankin, a space physicist at Princeton University and deputy project scientist of the Voyager mission] notes, astronomers of all stripes are trapped within that chaotic background in ways that may or may not affect their data and interpretations. "Every one of our measurements to date, until the Voyagers crossed the heliopause, has been filtered through all the different layers of the sun," Rankin says.

On their trek to interstellar space, the Voyagers had to cross a set of boundaries: first a termination shock some seven billion or eight billion miles away from the sun, where the solar wind abruptly begins to slow, then the heliopause, where the outward pressure from the solar wind is equaled by the inward pressure of the interstellar medium. Between these two stark borders lies the heliosheath, a region where solar material continues to slow and even reverse direction. The trek through these boundaries took Voyager 1, the faster of the twin probes, nearly eight years; such is the vastness of the scale at play.

Beyond the heliopause is interstellar space, which Voyager 1 entered in 2012 and Voyager 2 reached in 2018. It's a very different environment from the one inside our heliosphere — quieter but hardly quiescent. "It's a relic of the environment the solar system was born out of," Rankin says of the interstellar medium. Within it are energetic atomic fragments called galactic cosmic rays, as well as dust expelled by dying stars across the universe's eons, among other ingredient.
Earlier this month Wired noted " The secret of the Voyagers lies in their atomic hearts: both are equipped with three radioisotope thermoelectric generators, or RTGs — small power generators that can produce power directly on board. Each RTG contains 24 plutonium-238 oxide spheres with a total mass of 4.5 kilograms..." But as time passes, the plutonium on board is depleted, and so the RTGs produce less and less energy. The Voyagers are therefore slowly dying. Nuclear batteries have a maximum lifespan of 60 years. In order to conserve the probes' remaining energy, the mission team is gradually shutting down the various instruments on the probes that are still active...

Four active instruments remain, including a magnetometer as well as other instruments used to study the galactic environment, with its cosmic rays and interstellar magnetic field. But these are in their last years. In the next decade — it's hard to say exactly when — the batteries of both probes will be drained forever.
