What Happened After Google Retrofitted Memory Safety Onto Its C++ Codebase? (googleblog.com) 140

Google's transistion to Safe Coding and memory-safe languages "will take multiple years," according to a post on Google's security blog. So "we're also retrofitting secure-by-design principles to our existing C++ codebase wherever possible," a process which includes "working towards bringing spatial memory safety into as many of our C++ codebases as possible, including Chrome and the monolithic codebase powering our services." We've begun by enabling hardened libc++, which adds bounds checking to standard C++ data structures, eliminating a significant class of spatial safety bugs. While C++ will not become fully memory-safe, these improvements reduce risk as discussed in more detail in our perspective on memory safety, leading to more reliable and secure software... It's also worth noting that similar hardening is available in other C++ standard libraries, such as libstdc++. Building on the successful deployment of hardened libc++ in Chrome in 2022, we've now made it default across our server-side production systems. This improves spatial memory safety across our services, including key performance-critical components of products like Search, Gmail, Drive, YouTube, and Maps... The performance impact of these changes was surprisingly low, despite Google's modern C++ codebase making heavy use of libc++. Hardening libc++ resulted in an average 0.30% performance impact across our services (yes, only a third of a percent) ...

In just a few months since enabling hardened libc++ by default, we've already seen benefits. Hardened libc++ has already disrupted an internal red team exercise and would have prevented another one that happened before we enabled hardening, demonstrating its effectiveness in thwarting exploits. The safety checks have uncovered over 1,000 bugs, and would prevent 1,000 to 2,000 new bugs yearly at our current rate of C++ development...

The process of identifying and fixing bugs uncovered by hardened libc++ led to a 30% reduction in our baseline segmentation fault rate across production, indicating improved code reliability and quality. Beyond crashes, the checks also caught errors that would have otherwise manifested as unpredictable behavior or data corruption... Hardened libc++ enabled us to identify and fix multiple bugs that had been lurking in our code for more than a decade. The checks transform many difficult-to-diagnose memory corruptions into immediate and easily debuggable errors, saving developers valuable time and effort.

The post notes that they're also working on "making it easier to interoperate with memory-safe languages. Migrating our C++ to Safe Buffers shrinks the gap between the languages, which simplifies interoperability and potentially even an eventual automated translation."

Does Google Plan to Create Email Aliases for Apps to Fight Spam? (androidauthority.com) 27

Google appears to be working on an email-forwarding alias system, according to the blog Android Authority, giving users a new way to "shield" their main email address.

The site performed a teardown on the newest Google Play Services' APK looking for work-in-progress code , and spotted "a whole boatload of strings referencing and in support of something called 'Shielded Email'." Just from that text, we're able to infer quite a lot about what we're looking at here, and it appears that Shielded Email consists of a system to create single-use or limited-use email aliases that will forward messages along to your primary account. And while we could imagine that something like this might be pretty useful in Chrome, here it looks like Google is building it specifically to address apps that ask for your email address. The messages in there touch on a couple reasons beyond spam that you might want to keep your main email private, like reducing the extent to which your online activities can be tracked, and mitigating your personal risk from potential future data breaches.
They also sighted a reference to "Shielded Email" in the Autofill settings menu — though their article acknowledges that even features hinted at by work-in-progress code may not ultimately make it into a public release.

But Forbes suggests that the idea sounds similar to Apple's Hide My Email service, which "provides an automated random email address creator to help keep your personal email address private when subscribing to services."

Threads Grew By a Bluesky This Month, Now Has Over 275 Million Users (theverge.com) 44

An anonymous reader shared this report from the Verge: Bluesky might be on the rise, but Instagram and Threads boss Adam Mosseri wants you to know that Threads is still much bigger. In a post on Thursday, Mosseri said that Threads has gotten "more than 15 million signups in November alone," seemingly trying to throw some cold water over Bluesky crossing 15 million users total on Wednesday.

Mosseri also reiterated that the platform has been getting more than a million signups per day — a stat that CEO Mark Zuckerberg revealed during last month's earnings call — and noted that the platform has been seeing that volume of signups for "going on three months."

As November began, Mosseri posted that Threads had 275 million monthly active users....

'Automotive Grade Linux' Will Promote Open Source Program Offices for Automakers (prnewswire.com) 28

Automotive Grade Linux is a collaborative open source project developing "an open platform from the ground up that can serve as the de facto industry standard" for fast development of new features. Automakers have joined with tech companies and suppliers to speed up development (and adoption) of "a fully open software stack for the connected car" — hosted at the Linux Foundation, and "with Linux at its core..."

And this week they created a new Open Source Program Office expert group, led by Toyota, to promote the establishment of Open Source Program Offices within the automotive industry, "and encourage the sharing of information and best practices between them." Open source software has become more prevalent across the automotive industry as automakers invest more time and resources into software development. Automakers like Toyota and Subaru are using open source software for infotainment and instrument cluster applications. Other open source applications across the automotive industry include R&D, testing, vehicle-to-cloud and fleet management. "Historically, there has been little code contributed back to the open source community," said Dan Cauchy, Executive Director of Automotive Grade Linux. "Often, this was because the internal procedures or IT infrastructure weren't in place to support open source contributions. The rise of software-defined vehicles has led to a growing trend of automakers not just using, but also contributing, to open source software. Many organizations are also establishing Open Source Program Offices to streamline and organize open source activities to better support business goals."

Automakers including Toyota, Honda, and Volvo have already established Open Source Program Offices. The new AGL OSPO Expert Group provides a neutral space for them to share pain points and collaborate on solutions, exchange information, and develop best practices that can help other automakers build their own OSPOs. "Toyota has been participating in AGL and the broader open source community for over a decade," said Masato Endo, Group Manager of Open Source Program Group, Toyota. "We established an OSPO earlier this year to promote the use of open source software internally and to help guide how and where we contribute. We are looking forward to working with other open source leaders to solve common problems, collaborate on best practices, and invigorate open source activities in the automotive industry."

The AGL OSPO EG is led by Toyota with support from Panasonic and AISIN Corporation.

With First Mechanical Qubit, Quantum Computing Goes Steampunk (science.org) 14

An anonymous reader quotes a report from Science Magazine: Qubits, the strange devices at the heart of a quantum computer that can be set to 0, 1, or both at once, could hardly be more different from the mechanical clockwork used in the earliest computers. Today, most quantum computers rely on qubits made out of tiny circuits of superconducting metal, individual ions, photons, or other things. But now, physicists have made a working qubit from a tiny, moving machine, an advance that echoes back to the early 20th century when the first computers employed mechanical switches. "For many years, people were thinking it would be impossible to make a qubit from a mechanical system," says Adrian Bachtold, a condensed matter physicist at the Institute of Photonic Sciences who was not involved in the work, published today in Science. Stephan Durr, a quantum physicist at the Max Planck Institute for Quantum Optics, says the result "puts a new system on the map," which could be used in other experiments—and perhaps to probe the interface of quantum mechanics and gravity. [...]

The new mechanical qubit is unlikely to run more mature competition off the field any time soon. Its fidelity -- a measure of how well experimenters can set the state they desire -- is just 60%, compared with greater than 99% for the best qubits. For that reason, "it's an advance in principle," Bachtold says. But Durr notes that a mechanical qubit might serve as a supersensitive probe of forces, such as gravity, that don't affect other qubits. And ETHZ researchers hope to take their demonstration a step further by using two mechanical qubits to perform simple logical operations. "That's what Igor is working on now," [says Yiwen Chu, a physicist at ETH Zurich]. If they succeed, the physical switches of the very first computers will have made a tiny comeback.

Bluesky Says It Won't Train AI On Your Posts 51

Bluesky, the social network surging in popularity, says it has "no intention" of training AI tools on users content. "The social network made the announcement on the same day that X (formerly Twitter) is implementing its new terms of service that allow the platform to use public posts to train AI," notes TechCrunch. From the report: "A number of artists and creators have made their home on Bluesky, and we hear their concerns with other platforms training on their data," Bluesky said in a post on its app. "We do not use any of your content to train generative AI, and have no intention of doing so." The company went on to note that it uses AI internally to help with content moderation and that it also uses the technology in its "Discover" algorithmic feed. However, Bluesky says "none of these are Gen AI systems trained on user content."

Ask Slashdot: Have AI Coding Tools Killed the Joy of Programming? 143

Longtime Slashdot reader DaPhil writes: I taught myself to code at 12 years old in the 90s and I've always liked the back-and-forth with the runtime to achieve the right result. I recently got back from other roles to code again, and when starting a new project last year, I decided to give the new "AI assistants" a go.

My initial surprise at the quality and the speed you can achieve when using ChatGPT and/or Copilot when coding turned sour over the months, as I realized that all the joy I felt about trying to get the result I want -- slowly improving my code by (slowly) thinking, checking the results against the runtime, and finally achieving success -- is, well, gone. What I do now is type English sentences in increasingly desperate attempts to get ChatGPT to output what I want (or provide snippets to Copilot to get the right autocompletion), which -- as they are pretty much black boxes -- is frustrating and non-linear: it either "just works," or it doesn't. There is no measure of progress. In a way, having Copilot in the IDE was even worse, since it often disrupts my thinking when suggesting completions.

I've since disabled Copilot. Interestingly, I myself now feel somehow "disabled" without it in the IDE; however, the abstention has given me back the ability to sit back and think, and through that, the joy of programming. Still, it feels like I'm now somehow an ex-drug addict always on the verge of a relapse. I was wondering if any of you felt the same, or if I'm just... old.

The Rich Country With the Worst Mobile-Phone Service 72

Economist: Britain has long been a pioneer in telecoms. In 1837 it built the world's first commercial telegraph; the first transatlantic call was placed from London in 1927; in 1992 a British programmer sent the first text message to a mobile phone. Today it lags rather than leads. According to figures provided to The Economist by Opensignal, a research firm, Britain ranks 46th for download speeds out of the 56 developed and developing countries for which there are data. That gives it the worst mobile service in the rich world.

Some of this is due to demand. Over the past three years data usage on mobile devices has doubled as people stream films and play games. The busiest parts of cities often lack mobile reception because the system is at capacity. But mainly it is an issue of supply. British users of 5G are only on it 11% of the time. That puts Britain 43rd out of the 56 countries. This lacklustre performance is caused by a combination of government U-turns, insufficient investment and sclerotic planning.

Australia To Make Big Tech Liable For Citizens' Online Safety (yahoo.com) 79

An anonymous reader quotes a report from Bloomberg: The Australian government plans to enact laws requiring big tech firms to protect its citizens online, the latest move by the center-left Labor administration to crack down on social media including through age limits and curbs on misinformation. Communications Minister Michelle Rowland announced the government's plan for a legislated Digital Duty of Care in Australia on Wednesday night, saying it aligned with similar laws in the UK and European Union. "It is now time for industry to show leadership, and for social media to recognize it has a social responsibility," Rowland said in a speech in Sydney announcing the measures. It would "keep users safe and help prevent online harms."

In response to the laws, Facebook and Instagram operator Meta Platforms Inc. called for the restrictions to be handled by app stores, such as those run by Google and Apple Inc., rather than the platforms themselves. The government has ignored those requests, but has yet to announce what fines companies would face or what age verification information will need to be provided. At the same time, Albanese has moved forward controversial laws to target misinformation and disinformation online, which opponents have labeled an attack on freedom of speech.
Earlier this month, Albanese said the government would legislate for a ban on social media for children under 16, a policy the government says is world-leading. "Social media is doing harm to our kids and I'm calling time on it," Albanese told a news conference.

Meet Evo, the DNA-trained AI That Creates Genomes From Scratch (science.org) 32

sciencehabit shares a report from Science Magazine: What if, rather than scouring the internet, ChatGPT could search all of the DNA on Earth? That future just got a bit closer with Evo, an AI model reported today in Science. The program -- trained on billions of lines of genetic sequences -- can design new proteins and even whole genomes. Previous AIs could only interpret and predict relatively short sections of DNA, and they could only work with groups of nucleotides -- the A, C, G, T alphabet of DNA -- not individual nucleotides. To take things to the next level, researchers trained Evo on 300 billion nucleotides of sequence information.

In a first test, Evo bested other AI models on predicting the impact of mutations on protein performance. The team then had Evo design new versions of the CRISPR genome editor; the best designs were as good at cutting DNA as a commercial version. And in what study author Brian Hie, a computational biologist at Stanford University, calls the "most futuristic and crazy" part of the study, the researchers asked Evo to generate DNA sequences that are long enough to serve as genomes for bacteria -- a step toward AI-designed synthetic genomes.

Much of the work on AI occurs in secret at companies. But the researchers have released Evo publicly so that other researchers can use it, and Hie says the team has no plans to commercialize its creation. "For now, I see this as a research project."

Google Loses Yet Another AI Pioneer As Keras Creator Leaves 15

Francois Chollet, an AI pioneer and creator of the Keras framework, announced that he's leaving Google to co-found a new company. Neowin reports: In his parting message, Chollet assured that he would still be active with Keras and participate in its development on GitHub. His successor, Jeff Carpenter, will now lead Keras at Google, and Chollet expressed his full confidence in the team's future direction.

Keras has come a long way since Chollet released it in 2015, initially as a high-level neural network API meant for simplicity and accessibility. Keras quickly gained traction in the AI community for its user-friendly Python interface and compatibility with frameworks like TensorFlow, simplifying machine learning model building for developers across various levels.
Google published a blog post praising Chollet and reaffirming their commitment to Keras.

Last year, Google lost the "Godfather of AI," Geoffrey Hinton, who left the company after nearly a decade. He said he quit his job at Google so he can freely speak out about the risks of AI.

Second Life for Server Components (ieee.org) 31

Scientists have developed a method to reuse components from decommissioned data center servers, potentially reducing the carbon footprint of cloud computing infrastructure.

The research team from Microsoft, Carnegie Mellon University and the University of Washington demonstrated that older RAM modules and solid-state drives can be safely repurposed in new server builds without compromising performance, according to papers presented at recent computer architecture conferences.

When combined with energy-efficient processors, the prototype servers achieved an 8% reduction in total carbon emissions during Azure cloud service testing. Researchers estimate the approach could cut global carbon emissions by up to 0.2% if widely adopted. The cloud computing industry currently accounts for 3% of global energy consumption and could represent 20% of emissions by 2030, according to computing experts. Most data centers, including Microsoft's Azure, typically replace servers every 3-5 years.

Google Rolls Out Call Screening AI To Thwart Phone Fraudsters (googleblog.com) 37

Google is rolling out AI-powered scam call detection for Android phones, aiming to protect users from increasingly sophisticated phone fraud schemes. The new feature, available in beta for Pixel 6 and newer devices, analyzes conversation patterns in real-time to identify potential scams. When suspicious patterns emerge, such as urgently requesting fund transfers, the system alerts users through audio, haptic, and visual warnings.

The detection system operates entirely on-device using Google's machine learning models, with no call audio or transcripts stored or transmitted externally. While Pixel 9 devices utilize Google's advanced Gemini Nano AI model, earlier Pixel phones use the standard machine learning for detection, the company said. The feature, which is opt-in and can be disabled at any time, is currently limited to English-speaking Phone by Google beta users in the United States. Google plans to expand availability to additional Android devices in the future.

CFPB Looks To Place Google Under Federal Supervision 26

Washington Post: The Consumer Financial Protection Bureau has taken steps to place Google under formal federal supervision, an extraordinary move that could subject the technology giant to the regular inspections and other rigorous monitoring that the government imposes on major banks.

Google has fiercely resisted the idea over months of highly secretive talks, according to two people familiar with the discussions, who spoke on the condition of anonymity to describe them -- setting up what may ultimately be a major legal clash with vast implications for the CFPB's powers in the digital age.

The exact scope of the CFPB's concerns is not clear, and its order does not appear to be final. The political fate of the bureau's work under Director Rohit Chopra is also in doubt, as the watchdog agency braces for potentially significant changes to its leadership and agenda with the return of President-elect Donald Trump to the White House.

Formed in the aftermath of the 2008 financial crisis, the CFPB has broad powers to protect consumers from unfair, deceptive or predatory financial practices. That includes the ability to place certain firms under supervision, a status that can afford regulators direct access to the company's internal records to ensure their activities are sound -- and seek fixes if they are not.

Meta Fined $840 Million For Breaching EU Antitrust Rules (bloomberg.com) 41

The European Union has fined Meta $840 million for unfairly tying its Facebook Marketplace classified ads service to its social network, marking the company's first EU antitrust penalty.

The European Commission ruled Meta must stop bundling Marketplace with Facebook's social platform and cease imposing unfair conditions on competing classified ads services. Regulators found Meta exploited Facebook's massive user base to disadvantage rivals and used competitors' advertising data to enhance Marketplace.

EU antitrust chief Margrethe Vestager said Meta "tied its online classified ads service Facebook Marketplace to its personal social network Facebook and imposed unfair trading conditions on other online classified ads service providers."

Experts Testify US Is Running Secret UAP Programs (npr.org) 177

During a public joint hearing today titled "Unidentified Anomalous Phenomena: Exposing the Truth," four experts testified that the U.S. is running secret UAP programs, including crash retrieval and reverse-engineering programs for advanced nonhuman technology. Although the Pentagon maintains there's no evidence of alien spacecraft, witnesses like Luis Elizondo and Michael Gold argue that UAPs represent an intelligence enigma and call for open, stigma-free study to address potential security concerns and unknown scientific possibilities. NPR reports: Tim Gallaudet, retired rear admiral, U.S. Navy; CEO of Ocean STL Consulting, LLC
"Confirmation that UAPs are interacting with humanity came for me in January 2015," Gallaudet said in his written testimony (PDF). He describes being part of a pre-deployment naval exercise off the U.S. East Coast that culminated in the famous "Go Fast" video, in which a Navy F/A-18 jet's sensors recorded "an unidentified object exhibiting flight and structural characteristics unlike anything in our arsenal." He was among a group of commanders involved in the exercise who received an email containing the video, which was sent by the operations officer of Fleet Forces Command, Gallaudet said. "The very next day, the email disappeared from my account and those of the other recipients without explanation," he said.

Luis Elizondo, author and former Department of Defense official
Elizondo's written testimony (PDF) was brief and alleged that a secretive arms race is playing out on the global stage. "Let me be clear: UAP are real," he wrote. "Advanced technologies not made by our Government -- or any other government -- are monitoring sensitive military installations around the globe. Furthermore, the U.S. is in possession of UAP technologies, as are some of our adversaries." Elizondo is a former intelligence officer who later "managed a highly sensitive Special Access Program on behalf of the White House and the National Security Council," according to his official bio (PDF). "By 2012, [Elizondo] was the senior ranking person of the DOD's Advanced Aerospace Threat Identification Program, a secretive Pentagon unit that studied unidentified anomalous phenomena," his bio states, adding that he resigned in 2017.

Michael Gold, former NASA associate administrator of space policy and partnerships; member of NASA UAP Independent Study Team
Gold's written testimony (PDF) stressed the need for government agencies and academics to "overcome the pernicious stigma that continues to impede scientific dialogue and open discussions" about unexplained phenomena. "As the saying goes, the truth is out there," Gold said, "we just need to be bold enough and brave enough to face it."

Michael Shellenberger, founder of Public, a news outlet on the Substack platform
Shellenberger's testimony (PDF) ran to some 214 pages, including a lengthy timeline of UAP reports from 1947 to 2023. Shellenberger pressed the White House and Congress to act, calling for the adoption of UAP transparency legislation and cutting funds for any related programs that aren't disclosed to lawmakers. "UAP transparency is bi-partisan and critical to our national security," his written testimony stated.

IBM Boosts the Amount of Computation You Can Get Done On Quantum Hardware (arstechnica.com) 30

An anonymous reader quotes a report from Ars Technica: There's a general consensus that we won't be able to consistently perform sophisticated quantum calculations without the development of error-corrected quantum computing, which is unlikely to arrive until the end of the decade. It's still an open question, however, whether we could perform limited but useful calculations at an earlier point. IBM is one of the companies that's betting the answer is yes, and on Wednesday, it announced a series of developments aimed at making that possible. On their own, none of the changes being announced are revolutionary. But collectively, changes across the hardware and software stacks have produced much more efficient and less error-prone operations. The net result is a system that supports the most complicated calculations yet on IBM's hardware, leaving the company optimistic that its users will find some calculations where quantum hardware provides an advantage. [...]

Wednesday's announcement was based on the introduction of the second version of its Heron processor, which has 133 qubits. That's still beyond the capability of simulations on classical computers, should it be able to operate with sufficiently low errors. IBM VP Jay Gambetta told Ars that Revision 2 of Heron focused on getting rid of what are called TLS (two-level system) errors. "If you see this sort of defect, which can be a dipole or just some electronic structure that is caught on the surface, that is what we believe is limiting the coherence of our devices," Gambetta said. This happens because the defects can resonate at a frequency that interacts with a nearby qubit, causing the qubit to drop out of the quantum state needed to participate in calculations (called a loss of coherence). By making small adjustments to the frequency that the qubits are operating at, it's possible to avoid these problems. This can be done when the Heron chip is being calibrated before it's opened for general use.

Separately, the company has done a rewrite of the software that controls the system during operations. "After learning from the community, seeing how to run larger circuits, [we were able to] almost better define what it should be and rewrite the whole stack towards that," Gambetta said. The result is a dramatic speed-up. "Something that took 122 hours now is down to a couple of hours," he told Ars. Since people are paying for time on this hardware, that's good for customers now. However, it could also pay off in the longer run, as some errors can occur randomly, so less time spent on a calculation can mean fewer errors. Despite all those improvements, errors are still likely during any significant calculations. While it continues to work toward developing error-corrected qubits, IBM is focusing on what it calls error mitigation, which it first detailed last year. [...] The problem here is that using the function is computationally difficult, and the difficulty increases with the qubit count. So, while it's still easier to do error mitigation calculations than simulate the quantum computer's behavior on the same hardware, there's still the risk of it becoming computationally intractable. But IBM has also taken the time to optimize that, too. "They've got algorithmic improvements, and the method that uses tensor methods [now] uses the GPU," Gambetta told Ars. "So I think it's a combination of both."

Wi-Fi 8 Trades Speed For a More Reliable Experience (pcworld.com) 57

Wi-Fi 8 (also known as IEEE 802.11bn Ultra High Reliability) is expected to arrive around 2028, prioritizing an enhanced user experience over speed by optimizing interactions between devices and access points. While it retains similar bandwidth specifications as the previous standard, Wi-Fi 8 aims to improve network efficiency, reducing interference and congestion for a more reliable and adaptive connection. PCWorld's Mark Hachman reports: As of Nov. 2024, MediaTek believes that Wi-Fi 8 will look virtually identical to Wi-Fi 7 in several key areas: The maximum physical layer (PHY) rate will be the same at 2,880Mbps x 8, or 23Gbits/s. It will also use the same four frequency bands (2, 4, 5, and 6GHz) and the same 4096 QAM modulation across a maximum channel bandwidth of 320MHz. (A Wi-Fi 8 router won't get 23Gbps of bandwidth, of course. According to MediaTek, the actual peak throughput in a "clean," or laboratory, environment is just 80 percent or so of the hypothetical peak throughput, and actual, real-world results can be far less.)

Still, put simply, Wi-Fi 8 should deliver the same wireless bandwidth as Wi-Fi 7, using the same channels and the same modulation. Every Wi-Fi standard has also been backwards-compatible with its predecessors, too. What Wi-Fi 8 will do, though, is change how your client device, such as a PC or a phone, interacts with multiple access points. Think of this as an evolution of how your laptop talks to your home's networking equipment. Over time, Wi-Fi has evolved from communications between one laptop and a router, across a single channel. Channel hopping routed different clients to different bands. When Wi-Fi 6 was developed, a dedicated 6GHz channel was added, sometimes as a dedicated "backhaul" between your home's access points. Now, mesh networks are more common, giving your laptop a variety of access points, channels, and frequencies to select between.
For a detailed breakdown of the upcoming advancements coming to Wi-Fi 8, including Coordinated Spatial Reuse, Coordinated Beamforming, and Dynamic Sub-Channel Operation, read the full article.
