Robotics and machine learning engineer Naveen Kul developed WattWise, a lightweight open-source CLI tool that monitors power usage via smart plugs and throttles system performance based on electricity pricing and peak hours. Tom's Hardware reports: The simple program, called WattWise, came about when Naveen built a dual-socket EPYC workstation with plans to add four GPUs. It's a power-intensive setup, so he wanted a way to monitor its power consumption using a Kasa smart plug. The enthusiast has released the monitoring portion of the project to the public now, but the portion that manages clocks and power will be released later. Unfortunately, the Kasa Smart app and the Home Assistant dashboard was inconvenient and couldn't do everything he desired. He already had a terminal window running monitoring tools like htop, nvtop, and nload, and decided to take matters into his own hands rather than dealing with yet another app.

Naveen built a terminal-based UI that shows power consumption data through Home Assistant and the TP-Link integration. The app monitors real-time power use, showing wattage and current, as well as providing historical consumption charts. More importantly, it is designed to automatically throttle CPU and GPU performance. Naveen's power provider uses Time-of-Use (ToU) pricing, so using a lot of power during peak hours can cost significantly more. The workstation can draw as much as 1400 watts at full load, but by reducing the CPU frequency from 3.7 GHz to 1.5 GHz, he's able to reduce consumption by about 225 watts. (No mention is made of GPU throttling, which could potentially allow for even higher power savings with a quad-GPU setup.)

Results will vary based on the hardware being used, naturally, and servers can pull far more power than a typical desktop -- even one designed and used for gaming. WattWise optimizes the system's clock speed based on the current system load, power consumption as reported by the smart plug, and the time -- with the latter factoring in peak pricing. From there, it uses a Proportional-Integral (PI) controller to manage the power and adapts system parameters based on the three variables. A blog post with more information is available here.

WattWise is also available on GitHub.

An anonymous reader quotes a report from TechCrunch: Anthropic announced on Wednesday that it's launching a new Claude for Education tier, an answer to OpenAI's ChatGPT Edu plan. The new tier is aimed at higher education, and gives students, faculty, and other staff access to Anthropic's AI chatbot, Claude, with a few additional capabilities. One piece of Claude for Education is "Learning Mode," a new feature within Claude Projects to help students develop their own critical thinking skills, rather than simply obtain answers to questions. With Learning Mode enabled, Claude will ask questions to test understanding, highlight fundamental principles behind specific problems, and provide potentially useful templates for research papers, outlines, and study guides.

Anthropic says Claude for Education comes with its standard chat interface, as well as "enterprise-grade" security and privacy controls. In a press release shared with TechCrunch ahead of launch, Anthropic said university administrators can use Claude to analyze enrollment trends and automate repetitive email responses to common inquiries. Meanwhile, students can use Claude for Education in their studies, the company suggested, such as working through calculus problems with step-by-step guidance from the AI chatbot. To help universities integrate Claude into their systems, Anthropic says it's partnering with the company Instructure, which offers the popular education software platform Canvas. The AI startup is also teaming up with Internet2, a nonprofit organization that delivers cloud solutions for colleges.

Anthropic says that it has already struck "full campus agreements" with Northeastern University, the London School of Economics and Political Science, and Champlain College to make Claude for Education available to all students. Northeastern is a design partner -- Anthropic says it's working with the institution's students, faculty, and staff to build best practices for AI integration, AI-powered education tools, and frameworks. Anthropic hopes to strike more of these contracts, in part through new student ambassador and AI "builder" programs, to capitalize on the growing number of students using AI in their studies.

The FBI searched two homes of Indiana University Bloomington data privacy professor Xiaofeng Wang last week, following months of university inquiries into whether he received unreported research funding from China, WIRED reported Wednesday.

Wang, who leads the Center for Distributed Confidential Computing established with a $3 million National Science Foundation grant, was terminated on March 28 via email from the university provost. The university had contacted Wang in December regarding a 2017-2018 grant in China that listed him as a researcher, questioning whether he properly disclosed the funding to IU and in applications for U.S. federal research grants.

Jason Covert, Wang's attorney, said Wang and his wife Nianli Ma, whose employee profile was also removed, are "safe" and neither has been arrested. The couple's legal team has viewed a search warrant but received no affidavit establishing probable cause.

An anonymous reader shares a report: Amazon has put in a last-minute bid to acquire all of TikTok, the popular video app, as it approaches an April deadline to be separated from its Chinese owner or face a ban in the United States, according to three people familiar with the bid.

Various parties who have been involved in the talks do not appear to be taking Amazon's bid seriously, the people said. The bid came via an offer letter addressed to Vice President JD Vance and Howard Lutnick, the commerce secretary, according to a person briefed on the matter. Amazon's bid highlights the 11th-hour maneuvering in Washington over TikTok's ownership. Policymakers in both parties have expressed deep national security concerns over the app's Chinese ownership, and passed a law last year to force a sale of TikTok that was set to take effect in January.

Representatives Alexandria Ocasio-Cortez and Anna Paulina Luna introduced bipartisan legislation in March to cap credit card interest rates at 10% annually as Americans' debt hits record levels. "Credit cards with high interest rates regularly trap working people in endless cycles of debt," Ocasio-Cortez said in a statement.

Credit card debt has reached $1.2 trillion in Q4 2024, up from $720 billion in the same quarter of 2004, according to Federal Reserve Bank of New York data. Average annual percentage rates nearly doubled to 21% in 2024 from 12% in 2003. The Federal Reserve Bank of Philadelphia reported a record number of cardholders making only minimum payments in Q3 2024, "showing signs of consumer stress."

An anonymous reader quotes a report from TechCrunch: Zelle is shutting down its stand-alone app on Tuesday, according to a company blog post. This news might be alarming if you're one of the over 150 million customers in the U.S. who use Zelle for person-to-person payments. But only about 2% of transactions take place via Zelle's app, which is why the company is discontinuing its stand-alone app.

Most consumers access Zelle via their bank, which then allows them to send money to their phone contacts. Zelle users who relied on the stand-alone app will have to re-enroll in the service through another financial institution. Given the small user base of the Zelle app, it makes sense why the company would decide to get rid of it -- maintaining an app takes time and money, especially one where people's financial information is involved.

A new paper [PDF] from the AI Disclosures Project claims OpenAI likely trained its GPT-4o model on paywalled O'Reilly Media books without a licensing agreement. The nonprofit organization, co-founded by O'Reilly Media CEO Tim O'Reilly himself, used a method called DE-COP to detect copyrighted content in language model training data.

Researchers analyzed 13,962 paragraph excerpts from 34 O'Reilly books, finding that GPT-4o "recognized" significantly more paywalled content than older models like GPT-3.5 Turbo. The technique, also known as a "membership inference attack," tests whether a model can reliably distinguish human-authored texts from paraphrased versions.

"GPT-4o [likely] recognizes, and so has prior knowledge of, many non-public O'Reilly books published prior to its training cutoff date," wrote the co-authors, which include O'Reilly, economist Ilan Strauss, and AI researcher Sruly Rosenblat.

With the signing of HB25-1040 on Monday, Colorado now defines nuclear as a "clean energy resource" since it doesn't release large amounts of climate-warming emissions. "The category was previously reserved for renewables like wind, solar and geothermal, which don't carry the radioactive stigma that's hobbled fission power plants following disasters like Chernobyl and Fukushima," notes Colorado Public Radio. From the report: In an emailed statement, Ally Sullivan, a spokesperson for the governor's office, said the law doesn't advance any specific nuclear energy project, and no utility has proposed building a nuclear power plant in Colorado. It does, however, allow nuclear energy to potentially serve as one piece of the state's plan to tackle climate change. "If nuclear energy becomes sufficiently cost-competitive, it could potentially become part of Colorado's clean energy future. However, it must be conducted safely, without harming communities, depleting other natural resources or replacing other clean energy sources," Sullivan said.

By redefining nuclear energy as "clean," the law would let future fission-based power plants obtain local grants previously reserved for other carbon-free energy sources, and it would allow those projects to contribute to Colorado's renewable energy goals. It also aligns state law with a push to reshape public opinion of nuclear energy. Nuclear energy proponents promise new reactor designs are smaller and safer than hulking power plants built in the 20th century. By embracing those systems, bill supporters claimed Colorado could meet rising energy demand without abandoning its ambitious climate goals.

Substack has announced it will legally support foreign writers lawfully residing in the U.S. who face government targeting over their published work, partnering with the nonprofit FIRE to expand its existing Defender program. The Verge reports: In their announcement, Substack and FIRE mention the international Tufts University student who was arrested by federal agents last week. Her legal team links her arrest to an opinion piece she co-wrote for the school's newspaper last year, which criticized Tufts for failing to comply with requests to divest from companies with connections to Israel. "If true, this represents a chilling escalation in the government's effort to target critics of American foreign policy," Substack and FIRE write.

The initiative builds on Substack's Defender program, which already offers legal assistance for independent journalists and creators on the platform. The company says it has supported "dozens" of Substack writers facing claims of defamation and trademark infringement since it launched the program in the US in 2020. It has since brought Substack Defender to writers in Canada and the UK.

MoffettNathanson has crowned YouTube the "New King of All Media" as the Alphabet-owned video platform has become a major force in Hollywood, dominating time spent watching TV. From a report: The firm estimates that YouTube as a standalone business could be worth as much as $550 billion -- or nearly 30% of the tech giant's current valuation. The figure is based on the firm's analysis of enterprise value as a multiple of revenue in 2024 for Netflix (10.5x revenue), Meta (8.8x), Roku (2.4x), Warner Bros. Discovery (1.4x), Fox (1.3x) and Disney (1.3x).

In 2024, YouTube was the second-largest media company by revenue at $54.2 billion, trailing behind only Disney. However, the MoffettNathanson analysts predict YouTube will take the top spot in 2025, becoming a leader in both engagement and revenue. "YouTube has the potential to become the central aggregator for all things professional video, positioning itself to capture a share of the $85 billion consumer Pay TV market and the ~$30 billion streaming ex. Netflix market in the U.S.," they wrote in a Monday research note. "On monetization, when comparing YouTube's massive TV screen engagement to its estimated TV revenue, it remains significantly under-monetized relative to its scaled reach and differentiated offering. This signals a substantial runway for improving its monetization strategy."

Credit card interest rates, which averaged 23% in 2023, are significantly higher than any other major loan product primarily due to non-diversifiable default risk and banks' market power, according to research published by the Federal Reserve Bank of New York.

The comprehensive study, which analyzed 330 million monthly credit card accounts, found that while high default losses contribute to elevated rates, they explain only part of the picture. Even high-FICO borrowers pay spreads exceeding 7% above the federal funds rate. Researchers determined that credit card banks have substantial pricing power, achieved through exceptionally high operating expenses -- about 4-5% of dollar balances annually -- with marketing costs ten times higher than those at other banks.

"Credit card charge-off rates are highly correlated with default rates on banks' other loans as well as on corporate bonds," the researchers said, noting that default risk cannot be diversified away across lending markets, particularly during economic downturns. The study estimated that exposure to aggregate default risk carries a premium of 5.3% per year, which fully explains the relationship between return on assets and credit scores.

Credit cards are ubiquitous in American finance, with 74% of adults owning at least one card, and the payment method accounting for 70% of retail spending. According to the research, 60% of accounts carry balances month-to-month.

London's mayor has axed a cyber crime helpline for the victims of online abuse, triggering a backlash from campaigners who argue that women and girls will be left struggling to access vital support. From a report: The service, which was shut down on Tuesday, assisted victims of fraud, revenge porn and cyberstalking to protect their digital identity. During its 18-months of operation it led to 2,060 cases being opened. The helpline was launched in 2023 as a one-year pilot scheme with $220,000 in funding from the Mayor's Office for Policing and Crime (Mopac), and was later extended by six months.

Conservative London Assembly member Emma Best said an informal evaluation showed the helpline "was working" and was going to be extended for another year. However, Sadiq Khan said that the scheme would be closed. "It was a pilot and pilots are what they say on the tinâ... we will receive an end of project report, we have collected the data and the results of that report will inform our future work," he said, speaking at Mayor's Question Time.

Economic models have systematically underestimated how global heating will affect people's wealth, according to a new study that finds 4C warming will make the average person 40% poorer -- an almost four-fold increase on some estimates. The Guardian: The study by Australian scientists suggests average per person GDP across the globe will be reduced by 16% even if warming is kept to 2C above pre-industrial levels. This is a much greater reduction than previous estimates, which found the reduction would be 1.4%.

Scientists now estimate global temperatures will rise by 2.1C even if countries hit short-term and long-term climate targets. Criticisms have mounted in recent years that a set of economic tools known as integrated assessment models (IAM) -- used to guide how much governments should invest in cutting greenhouse gas emissions -- have failed to capture major risks from climate change, particularly extreme weather events. The new study, in the journal Environmental Research Letters, took one of the most popular economic models and enhanced it with climate change forecasts to capture the impacts of extreme weather events across global supply chains.

Britain's flagship AI agency will slash the number of projects it backs and prioritize work on defense, environment and health as it seeks to respond to technological advances and criticism of its record. From a report: The Alan Turing Institute -- named after the pioneering British computer scientist -- will shut or offload almost a quarter of its 101 current initiatives and is considering job cuts as part of a change programme that led scores of staff to write a letter expressing their loss of confidence in the leadership in December.

Jean Innes, appointed chief executive in July 2023, argued that huge advances in AI meant the Turing needed to modernise after being founded as a national data science institute by David Cameron's government a decade ago this month. "The Turing has chalked up some really great achievements," Innes said in an interview. "[But we need] a big strategic shift to a much more focused agenda on a small number of problems that have an impact in the real world." A review last year by UK Research and Innovation, the government funding body, found "a clear need for the governance and leadership structure of the Institute to evolve." It called for a move away from the dominance of universities to a structure more representative of AI in UK.

OpenAI plans to release a new open-weight language model -- its first since GPT-2 -- in the coming months and is seeking community feedback to shape its development. "That's according to a feedback form the company published on its website Monday," reports TechCrunch. "The form, which OpenAI is inviting 'developers, researchers, and [members of] the broader community' to fill out, includes questions like 'What would you like to see in an open-weight model from OpenAI?' and 'What open models have you used in the past?'" From the report: "We're excited to collaborate with developers, researchers, and the broader community to gather inputs and make this model as useful as possible," OpenAI wrote on its website. "If you're interested in joining a feedback session with the OpenAI team, please let us know [in the form] below." OpenAI plans to host developer events to gather feedback and, in the future, demo prototypes of the model. The first will take place in San Francisco within a few weeks, followed by sessions in Europe and Asia-Pacific regions.

OpenAI is facing increasing pressure from rivals such as Chinese AI lab DeepSeek, which have adopted an "open" approach to launching models. In contrast to OpenAI's strategy, these "open" competitors make their models available to the AI community for experimentation and, in some cases, commercialization.
