Hackers Can Remotely Trigger the Brakes on American Trains and the Problem Has Been Ignored for Years

Slashdot.org - Tue, 07/15/2025 - 13:50
Many trains in the U.S. are vulnerable to a hack that can remotely lock a train's brakes, according to the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the researcher who discovered the vulnerability. From a report:The railroad industry has known about the vulnerability for more than a decade but only recently began to fix it. Independent researcher Neil Smith first discovered the vulnerability, which can be exploited over radio frequencies, in 2012. "All of the knowledge to generate the exploit already exists on the internet. AI could even build it for you," Smith told 404 Media. "The physical aspect really only means that you could not exploit this over the internet from another country, you would need to be some physical distance from the train [so] that your signal is still received."

Perplexity CEO Says Tech Giants 'Copy Anything That's Good'

Slashdot.org - Tue, 07/15/2025 - 13:10
Perplexity CEO Aravind Srinivas warned young entrepreneurs that tech giants will "copy anything that's good" during a talk at Y Combinator's AI Startup School, telling founders they must "live with that fear." Srinivas said that companies raising tens of billions need to justify capital expenditures and search for new revenue streams. Perplexity pioneered web-crawling chatbots when it launched its answer engine in December 2022, but Google's Bard added internet-crawling three months later, followed by ChatGPT in May 2023 and Anthropic's Claude in March 2025. The competition has extended to browsers, with Perplexity launching its Comet browser on July 9 and Reuters reporting that OpenAI is developing a web browser to challenge Google Chrome. Perplexity's communications head Jesse Dwyer said larger companies will "drown your voice."

NIST Ion Clock Sets New Record for Most Accurate Clock in the World

Slashdot.org - Tue, 07/15/2025 - 12:34
NIST: There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped aluminum ion. Part of the latest wave of optical atomic clocks, it can perform timekeeping with 19 decimal places of accuracy. Optical clocks are typically evaluated on two levels -- accuracy (how close a clock comes to measuring the ideal "true" time, also known as systematic uncertainty) and stability (how efficiently a clock can measure time, related to statistical uncertainty). This new record in accuracy comes out of 20 years of continuous improvement of the aluminum ion clock. Beyond its world-best accuracy, 41% greater than the previous record, this new clock is also 2.6 times more stable than any other ion clock. Reaching these levels has meant carefully improving every aspect of the clock, from the laser to the trap and the vacuum chamber. The team published its results in Physical Review Letters. "It's exciting to work on the most accurate clock ever," said Mason Marshall, NIST researcher and first author on the paper. "At NIST we get to carry out these long-term plans in precision measurement that can push the field of physics and our understanding of the world around us."

Nearly 3 Out of 4 Oracle Java Users Say They've Been Audited in the Past 3 Years

Slashdot.org - Tue, 07/15/2025 - 11:45
A survey of 500 IT asset managers in organizations that use Oracle Java has found that 73% have been audited in the last three years. From a report: At the same time, nearly eight out of 10 Oracle Java users said they had migrated, or planned to shift, to open source Java to try to avoid the risk and high costs of the dominant vendor's development and runtime environments. Oracle introduced a paid subscription for Java in September 2018, and in January 2023, it decided to switch its pricing model to per employee rather than per user, creating a steep price hike for many users. In July 2023, Gartner recorded users experiencing price increases of between two and five times when they switched to the new licensing model. Two years later, the survey conducted by market research firm Dimensional Research showed only 14% of Oracle Java users intended to stick with the vendor's subscription model.

Young Americans Face Job Market Disconnect as Parents Offer Outdated Career Advice

Slashdot.org - Tue, 07/15/2025 - 11:12
Nearly half of young Americans feel unprepared for future jobs as AI reshapes the workforce faster than career guidance can adapt, according to a new study from the Schultz Family Foundation and HarrisX. The survey of thousands of workers aged 16-24, along with parents, counselors and employers, revealed differences between generations about job availability and requirements. While 71% of employers say sufficient opportunities exist, only 43% of young people agree. Parents rely on outdated personal experiences when advising children, with 79% drawing from their own career paths despite 66% believing their children should pursue different directions. Employers require at least one year of experience for 77% of entry-level positions while offering internships for just 38% of roles.

Hugging Face Is Hosting 5,000 Nonconsensual AI Models of Real People

Slashdot.org - Tue, 07/15/2025 - 10:20
An anonymous reader shares a report: Hugging Face, a company with a multi-billion dollar valuation and one of the most commonly used platforms for sharing AI tools and resources, is hosting over 5,000 AI image generation models that are designed to recreate the likeness of real people. These models were all previously hosted on Civitai, an AI model sharing platform 404 Media reporting has shown was used for creating nonconsensual pornography, until Civitai banned them due to pressure from payment processors. Users downloaded the models from Civitai and reuploaded them to Hugging Face as part of a concerted community effort to archive the models after Civitai announced in May it will ban them. In that announcement, Civitai said it will give the people who originally uploaded them "a short period of time" before they were removed. Civitai users began organizing an archiving effort on Discord earlier in May after Civitai indicated it had to make content policy changes due to pressure from payment processors, and the effort kicked into high gear when Civitai announced the new "real people" model policy.
