Van Allen Probe A, a 1,300-pound (600 kg) NASA satellite launched in 2012 to study Earth's radiation belts, is expected to re-enter Earth's atmosphere this week. While most of it is expected to burn up during descent, "some components may survive," reports the BBC. "The space agency said there is a one in 4,200 chance of being harmed by a piece of the probe, which it characterized as 'low' risk." From the report: The spacecraft is projected to re-enter around 19:45 EST (00:45 GMT) on Tuesday the U.S. Space Force predicted, according to Nasa, though there is a 24-hour margin of "uncertainty" in the timing. [...] The spacecraft and its twin, Van Allen Probe B, were on a mission to gather unprecedented data on Earth's two permanent radiation belts. It was not immediately clear where in Earth's atmosphere the satellite is projected to re-enter. NASA and the U.S. Space Force has said it will monitor the re-entry and update any predictions. [...] Van Allen Probe B is not expected to re-enter the Earth's atmosphere before 2030.

An anonymous reader quotes a report from the Financial Times: Amazon's ecommerce business has summoned a large group of engineers to a meeting on Tuesday for a "deep dive" into a spate of outages, including incidents tied to the use of AI coding tools. The online retail giant said there had been a "trend of incidents" in recent months, characterized by a "high blast radius" and "Gen-AI assisted changes" among other factors, according to a briefing note for the meeting seen by the FT. Under "contributing factors" the note included "novel GenAI usage for which best practices and safeguards are not yet fully established."

"Folks, as you likely know, the availability of the site and related infrastructure has not been good recently," Dave Treadwell, a senior vice-president at the group, told employees in an email, also seen by the FT. The note ahead of Tuesday's meeting did not specify which particular incidents the group planned to discuss. [...] Treadwell, a former Microsoft engineering executive, told employees that Amazon would focus its weekly "This Week in Stores Tech" (TWiST) meeting on a "deep dive into some of the issues that got us here as well as some short immediate term initiatives" the group hopes will limit future outages.

He asked staff to attend the meeting, which is normally optional. Junior and mid-level engineers will now require more senior engineers to sign off any AI-assisted changes, Treadwell added. Amazon said the review of website availability was "part of normal business" and it aims for continual improvement. "TWiST is our regular weekly operations meeting with a specific group of retail technology leaders and teams where we review operational performance across our store," the company said.

Tony Hoare, the Turing Award-winning pioneer who created the Quicksort algorithm, developed Hoare logic, and advanced theories of concurrency and structured programming, has died at age 92.

News of his passing was shared today in a blog post. The site I Programmer also commemorated Hoare in a post highlighting his contributions to computer science and the lasting impact of his work. Personal accounts have been shared on Hacker News and Reddit.

Many Slashdotters may know Hoare for his aphorism regarding software design: "There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult."

An anonymous reader quotes a report from IEEE Spectrum: Worried that your latest ask to a cloud-based AI reveals a bit too much about you? Want to know your genetic risk of disease without revealing it to the services that compute the answer? There is a way to do computing on encrypted data without ever having it decrypted. It's called fully homomorphic encryption, or FHE. But there's a rather large catch. It can take thousands -- even tens of thousands -- of times longer to compute on today's CPUs and GPUs than simply working with the decrypted data. So universities, startups, and at least one processor giant have been working on specialized chips that could close that gap. Last month at the IEEE International Solid-State Circuits Conference (ISSCC) in San Francisco, Intel demonstrated its answer, Heracles, which sped up FHE computing tasks as much as 5,000-fold compared to a top-of the-line Intel server CPU.

Startups are racing to beat Intel and each other to commercialization. But Sanu Mathew, who leads security circuits research at Intel, believes the CPU giant has a big lead, because its chip can do more computing than any other FHE accelerator yet built. "Heracles is the first hardware that works at scale," he says. The scale is measurable both physically and in compute performance. While other FHE research chips have been in the range of 10 square millimeters or less, Heracles is about 20 times that size and is built using Intel's most advanced, 3-nanometer FinFET technology. And it's flanked inside a liquid-cooled package by two 24-gigabyte high-bandwidth memory chips—a configuration usually seen only in GPUs for training AI.

In terms of scaling compute performance, Heracles showed muscle in live demonstrations at ISSCC. At its heart the demo was a simple private query to a secure server. It simulated a request by a voter to make sure that her ballot had been registered correctly. The state, in this case, has an encrypted database of voters and their votes. To maintain her privacy, the voter would not want to have her ballot information decrypted at any point; so using FHE, she encrypts her ID and vote and sends it to the government database. There, without decrypting it, the system determines if it is a match and returns an encrypted answer, which she then decrypts on her side. On an Intel Xeon server CPU, the process took 15 milliseconds. Heracles did it in 14 microseconds. While that difference isn't something a single human would notice, verifying 100 million voter ballots adds up to more than 17 days of CPU work versus a mere 23 minutes on Heracles.

Last November, Amazon sued Perplexity demanding that the AI search startup stop allowing its AI browser agent, Comet, to make purchases for users online. Today, a judge ruled in favor of the tech giant, granting it a temporary court injunction blocking the scraping of Amazon's website. According to court filings, the judge found strong evidence the tool accessed the retailer's systems "without authorization." CNBC reports: In a ruling dated Monday, U.S. District Judge Maxine Chesney wrote that Amazon has provided "strong evidence" that Perplexity's Comet browser accessed its website at the user's direction, but "without authorization" from the e-commerce giant. Chesney said Amazon submitted "essentially undisputed evidence" that it spent more than $5,000 to respond to the issue, including "numerous hours" where its employees worked to develop tools to block Comet from accessing its private customer tools and to prevent the tool from "future unauthorized access." "Given such evidence, the Court finds Amazon has shown a likelihood of success on the merits of its claim," Chesney wrote.

Chesney's ruling includes a weeklong stay to allow Perplexity to appeal the order. Amazon wrote in its original complaint that Perplexity's agents posed security risks to customer data because they "can act within protected computer systems, including private customer accounts requiring a password." The company also said Perplexity's agents created challenges for the company's advertising business, because when AI systems generate ad traffic, the impressions have to be detected and filtered out before advertisers can be billed. "This requires modifications to Amazon's advertising systems, including developing new detection mechanisms to identify and exclude automated traffic," Amazon wrote in its complaint. "These system adaptations are necessary to maintain contractual obligations with advertisers who pay only for legitimate human impressions."

sziring shares a report from Business Insider: Silicon Valley has long competed for talent with ever-richer pay packages built around salary, bonus, and equity. Now, a fourth line item is creeping into the mix: AI inference. As generative AI tools become embedded in software development, the cost of running the underlying models -- known as inference -- is emerging as a productivity driver and a budget line that finance chiefs can't ignore.

Software engineers and AI researchers inside tech companies have already been jousting for access to GPUs, with this AI compute capacity being carefully parceled out based on which projects are most important. Now, some tech job candidates have begun asking about what AI compute budget they will have access to if they decide to join.

"I am increasingly asked during candidate interviews how much dedicated inference compute they will have to build with Codex," Thibault Sottiaux, engineering lead at OpenAI's Codex, the startup's AI coding service, wrote on X recently. He added that usage per user is growing much faster than overall user growth, a sign that AI compute is becoming even scarcer and more valuable. That scarcity is reshaping how engineers think about their work and pay. "The inference compute available to you is increasingly going to drive overall software productivity," said OpenAI President Greg Brockman.

The report cites a recent compensation submission from a software engineer that listed "Copilot subscription" as part of the pay and benefits. "OpenAI and Anthropic should create recruitment sites where their clients can advertise roles, listing the token budget for the job alongside the salary range," said Peter Gostev, AI capability lead at Arena, a startup that measures the performance of models.

Tomasz Tunguz of Theory Ventures predicts AI inference will be the fourth component of engineering compensation, alongside salary, bonus, and equity. "Will you be paid in tokens? In 2026, you likely will start to be," Tunguz said.

AT&T plans to invest more than $250 billion over the next five years to expand U.S. telecom infrastructure for the AI age. The company says it will also hire thousands of technicians while partnering with AST SpaceMobile to extend coverage to remote areas. Reuters reports: Rapid adoption of artificial intelligence, cloud computing and connected devices has prompted telecom operators to invest heavily in fiber and 5G networks as they also seek to fend off intensifying competition from cable broadband providers. AT&T, which has about 110,000 employees in the U.S., said the new hires will help build and maintain its infrastructure. The outlay includes capital expenditure and other spending, the company said.

The spending will focus on expanding its fiber and wireless networks, including accelerating deployment of fiber broadband, 5G home internet and satellite connectivity to extend coverage across urban, suburban and rural areas. [...] AT&T is also working with satellite partner AST SpaceMobile to expand connectivity to remote regions where traditional network infrastructure is difficult to deploy. The company said it would continue spending on the FirstNet network built for first responders and bolster investment in network security and artificial intelligence-driven threat detection.

Since 1999, Slashdot has been covering the annual Ig Nobel prize ceremonies -- which honor real scientific research into strange or surprising subjects. "After 35 years in Boston, the annual prize ceremony will take place in Zurich, Switzerland, this year and will continue to be held in a European city for the foreseeable future," reports Ars Technica. "The reason: concerns about the safety of international travelers, who are increasingly reluctant to travel to the U.S. to participate."

"During the past year, it has become unsafe for our guests to visit the country," Marc Abrahams, master of ceremonies and editor of The Annals of Improbable Research magazine, told The Associated Press. "We cannot in good conscience ask the new winners, or the international journalists who cover the event, to travel to the U.S. this year." It comes on the heels of our recent story that many international game developers are opting to skip this year's weeklong Game Developers Conference in San Francisco, citing similar concerns. Ars Technica reports: Established in 1991, the Ig Nobels are a good-natured parody of the Nobel Prizes; they honor "achievements that first make people laugh and then make them think." As the motto implies, the research being honored might seem ridiculous at first glance, but that doesn't mean it's devoid of scientific merit. The unapologetically campy awards ceremony features miniature operas, scientific demos, and the 24/7 lectures, in which experts must explain their work twice: once in 24 seconds and again in just seven words.

Traditionally, the awards ceremony and related Ig Nobel events have taken place in Boston at Harvard University, Massachusetts Institute of Technology, and Boston University. However, four of last year's 10 winners opted to skip the ceremony rather than travel to the U.S., and the situation has not improved. [...] [T]his year, the Ig Nobel organizers are joining forces with the ETH Domain and the University of Zurich for hosting duties. "Switzerland has nurtured many unexpected good things -- Albert Einstein's physics, the world economy, and the cuckoo clock leap to mind -- and is again helping the world appreciate improbable people and ideas," Abraham said.

The Ig Nobels will not be returning to the U.S. any time soon. Instead, the plan is for Zurich to host every second year; every odd-numbered year, the ceremony will be hosted by a different European city. Abraham likened the arrangement to the Eurovision Song Contest.

OpenAI is reportedly backing away from expanding its AI data center partnership with Oracle because newer generations of Nvidia GPUs may arrive before the facility is even operational. CNBC reports: Artificial intelligence chips are getting upgraded more quickly than data centers can be built, a market reality that exposes a key risk to the AI trade and Oracle's debt-fueled expansion. OpenAI is no longer planning to expand its partnership with Oracle in Abilene, Texas, home to the Stargate data center, because it wants clusters with newer generations of Nvidia graphics processing units, according to a person familiar with the matter.

The current Abilene site is expected to use Nvidia's Blackwell processors, and the power isn't projected to come online for a year. By then, OpenAI is hoping to have expanded access to Nvidia's next-generation chips in bigger clusters elsewhere, said the person, who asked not to be named due to confidentiality. In a post on X, Oracle called the reports "false and incorrect." However, it only said existing projects are on track and didn't address expansion plans.

CNBC notes: "Oracle secured the site, ordered the hardware, and spent billions of dollars on construction and staff, with the expectation of going bigger."

An anonymous reader quotes a report from The Register: AI can reverse engineer machine code and find vulnerabilities in ancient legacy architectures, says Microsoft Azure CTO Mark Russinovich, who used his own Apple II code from 40 years ago as an example. Russinovich wrote: "We are entering an era of automated, AI-accelerated vulnerability discovery that will be leveraged by both defenders and attackers."

In May 1986, Russinovich wrote a utility called Enhancer for the Apple II personal computer. The utility, written in 6502 machine language, added the ability to use a variable or BASIC expression for the destination of a GOTO, GOSUB, or RESTORE command, whereas without modification Applesoft BASIC would only accept a line number. Russinovich had Claude Opus 4.6, released early last month, look over the code. It decompiled the machine language and found several security issues, including a case of "silent incorrect behavior" where, if the destination line was not found, the program would set the pointer to the following line or past the end of the program, instead of reporting an error. The fix would be to check the carry flag, which is set if the line is not found, and branch to an error.

The existence of the vulnerability in Apple II type-in code has only amusement value, but the ability of AI to decompile embedded code and find vulnerabilities is a concern. "Billions of legacy microcontrollers exist globally, many likely running fragile or poorly audited firmware like this," said one comment to Russinovich's post.

Axios reports that Meta has acquired Moltbook, the viral, Reddit-like social network designed for AI agents. Humans are welcome, but only to observe. Axios reports: The deal brings Moltbook's creators -- Matt Schlicht and Ben Parr -- into Meta Superintelligence Labs (MSL), the unit run by former Scale AI CEO Alexandr Wang. Meta did not disclose Moltbook's purchase price. The deal is expected to close mid-March, Meta says, with the pair starting at MSL on March 16. When it launched in late January, Moltbook was labeled the "most interesting place on the internet" by open-source developer and writer Simon Willison. "Browsing around Moltbook is so much fun. A lot of it is the expected science fiction slop, with agents pondering consciousness and identity. There's also a ton of genuinely useful information, especially on m/todayilearned."

In an internal post seen by Axios, Meta's Vishal Shah said existing Moltbook customers can temporarily continue using the platform. "The Moltbook team has given agents a way to verify their identity and connect with one another on their human's behalf," Shah says. "This establishes a registry where agents are verified and tethered to human owners." He added: "Their team has unlocked new ways for agents to interact, share content, and coordinate complex tasks."

German publishers and advertising groups are urging regulators to fine Apple over its App Tracking Transparency (ATT) system, arguing it unfairly restricts access to advertising data while allowing Apple to remain the central gatekeeper -- without subjecting its own apps to the same restrictions. If Germany's antitrust authority does rule against Apple, the company could face fines of up to 10% of its global revenue. 9to5Mac reports: One of the countries investigating whether ATT is anticompetitive is Germany. Last year, in an attempt to appease the country's antitrust watchdog, the company proposed several changes to the framework's rules. From Reuters' original coverage of Apple's changes proposals: "Apple had agreed to introduce neutral consent prompts for both its own services and third-party apps, and to largely align the wording, content and visual design of these messages, said Andreas Mundt, head of Germany's Bundeskartellamt. The company also proposed simplifying the consent process so developers can obtain user permission for advertising-related data processing in a way that complies with data protection law." [...] At the time, German regulators launched a consultation with industry publications to determine whether the proposals addressed their concerns. As it turns out, the answer was a hard no.

As Reuters reported today: "Apple's proposed changes to its app tracking rules do not resolve antitrust issues in the mobile advertising market, associations representing German publishers and advertisers said on Tuesday as they urged the country's antitrust authority to slap a fine on the U.S. tech giant. [...] 'The proposed commitments would not change the negative effects of the App Tracking Transparency Framework,' Bernd Nauen, chief executive of the German Advertising Federation, said in a joint letter signed by the trade bodies. 'Apple would remain the data gatekeeper and would continue to decide who gets access to advertising-relevant data and how companies can communicate with their end customers,' he said."

Private equity firm EQT AB is reportedly exploring a sale of SUSE that could value the open-source Linux pioneer at up to $6 billion, roughly doubling the valuation since EQT took the company private in 2023. Reuters reports: EQT "has hired investment bank Arma Partners to sound out a group of private equity investors for a possible sale of the company, said the sources, who requested anonymity to discuss confidential matters. The deliberations are at "an early stage and there is no certainty that EQT will proceed with "a transaction, the sources said. [...] The potential deal comes amid a broader selloff in software stocks, which has disrupted mergers and acquisitions activity. Investors are "concerned that new artificial intelligence tools could displace many existing software products, weighing on technology "valuations and making deals harder to price.

Some investors, however, see Luxembourg-headquartered SUSE as a potential beneficiary of AI adoption, arguing that demand for enterprise-grade infrastructure software is likely to grow as companies build and deploy more AI applications. The company generates about $800 million in revenue and more than $250 million in earnings before interest, taxes, depreciation, and amortization (EBITDA) and could fetch between $4 billion and $6 billion in a sale, the sources said.

An anonymous reader quotes a report from Ars Technica: This week, tens of thousands of game developers and producers will once again gather in San Francisco, as they have since 1988, for the weeklong Game Developers Conference. But this year's show will be missing many international developers who say they no longer feel comfortable traveling to the United States to attend, no matter how relevant the show is to their work and careers. Dozens of those developers who spoke to Ars in recent months say they're wary of traveling to a country that has shown a callous disregard for -- or outright hostility toward -- the safety of international travelers. That's especially true for developers from various minority groups, those with transgender identities, and those who feel they could be targeted for outspoken political beliefs. "I honestly don't know anyone who is not from the U.S. who is planning on going to the next GDC," Godot Foundation Executive Director Emilio Coppola, who's based in Spain, told Ars. "We never felt super safe, but now we are not willing to risk it." "I honestly don't know anyone who is not from the U.S. who is planning on going to the next GDC," says Godot Foundation Executive Director Emilio Coppola, who's based in Spain. "We never felt super safe, but now we are not willing to risk it."

"Hearing European citizens getting arrested by border control over their views on the U.S. is not something I would like to test for myself," adds Nazih Fares, a French-Lebanese citizen and creative director at indie studio Le Cabinet du Savoir..

Many of the developers who spoke to Ars cite the intrusive questioning, racial profiling, and other horror stories reported at the U.S. border. "I read a few long reads about how UK/German tourists ended up detained, and that was the final straw for me," Austrian-based Cohop Game founder Eline Muijres said. "It doesn't feel safe for me."

Domini Gee, a Canadian game writer and narrative designer echoed that concern, adding: "There's no shortage of stories... about the risk of detainment, deportation, phones being searched... the consequences if I'm not [OK] could be high."

The FBI is investigating a breach affecting systems tied to wiretapping and surveillance warrant data, after abnormal logs revealed possible unauthorized access to law-enforcement-sensitive information. "The FBI identified and addressed suspicious activities on FBI networks, and we have leveraged all technical capabilities to respond," a spokesperson for the bureau said. "We have nothing additional to provide." The Register reports: [W]hile the FBI declined to provide any additional information, it's worth noting that China's Salt Typhoon previously compromised wiretapping systems used by law enforcement. Salt Typhoon is the PRC-backed crew that famously hacked major US telecommunications firms and stole information belonging to nearly every American.

According to the Associated Press, the FBI notified Congress that it began investigating the breach on February 17 after spotting abnormal log information related to a system on its network. "The affected system is unclassified and contains law enforcement sensitive information, including returns from legal process, such as pen register and trap and trace surveillance returns, and personally identifiable information pertaining to subjects of FBI investigations," the notification said.
