  • Cursor CEO Warns Vibe Coding Builds 'Shaky Foundations' That Eventually Crumble
    by msmash on 26/12/2025 at 7:00 am

    Michael Truell, the 25-year-old CEO and cofounder of Cursor, is drawing a sharp distinction between careful AI-assisted development and the more hands-off approach commonly known as "vibe coding." Speaking at a conference, Truell described vibe coding as a method where users "close your eyes and you don't look at the code at all and you just ask the AI to go build the thing for you." He compared it to constructing a house by putting up four walls and a roof without understanding the underlying wiring or floorboards. The approach might work for quickly mocking up a game or website, but more advanced projects face real risks. "If you close your eyes and you don't look at the code and you have AIs build things with shaky foundations as you add another floor, and another floor, and another floor, and another floor, things start to kind of crumble," Truell said. Truell and three fellow MIT graduates created Cursor in 2022. The tool embeds AI directly into the integrated development environment and uses the context of existing code to predict the next line, generate functions, and debug errors. The difference, as Truell frames it, is that programmers stay engaged with what's happening under the hood rather than flying blind. Read more of this story at Slashdot.

  • Apple's App Course Runs $20,000 a Student. Is It Really Worth It?
    by msmash on 26/12/2025 at 4:30 am

    Apple's Developer Academy in Detroit has spent roughly $30 million over four years training hundreds of people to build iPhone apps, but not everyone lands coding jobs right away, according to a WIRED story published this week. The program launched in 2021 as part of Apple's $200 million response to the Black Lives Matter protests and costs an estimated $20,000 per student -- nearly twice what state and local governments budget for community colleges. About 600 students have completed the 10-month course at Michigan State University. Academy officials say 71% of graduates from the past two years found full-time jobs across various industries. The program provides iPhones, MacBooks and stipends ranging from $800 to $1,500 per month, though one former student said many participants relied on food stamps. Apple contributed $11.6 million to the academy. Michigan taxpayers and the university's regular students covered about $8.6 million -- nearly 30% of total funding. Two graduates said their lack of proficiency in Android hurt their job prospects. Apple's own US tech workforce went from 6% Black before the academy opened to about 3% this year.

  • Gmail Users May Soon Be Able To Change Their Email Address and Keep the Old One
    by msmash on 26/12/2025 at 1:55 am

    Google appears to be testing a feature that would let users change their @gmail.com address for the first time, according to an official support document. The support page exists only in Hindi, suggesting an India-first rollout, and Google notes that users will "gradually begin to see this option." The feature would let users switch to a new @gmail address while retaining full access to their old one, effectively giving a single account two working email addresses. Emails sent to either address would arrive in the same inbox, and existing data in Drive and Photos would remain unaffected. Users who switch cannot register another new address for 12 months. Google has not officially announced the feature. Read more of this story at Slashdot.

  • Apple Settles Brazilian Antitrust Case, Must Allow Third-Party App Stores and External Payment Links
    by msmash on 26/12/2025 at 12:39 am

    Apple has agreed to a settlement with Brazil's antitrust regulator that will require the company to allow third-party app stores on iPhones and permit developers to direct users to external payment options, marking another country where Apple's tightly controlled App Store model is being pried open by government action. Brazil's Administrative Council of Economic Defense approved the settlement this week, resolving an investigation that began in 2022 into whether Apple's restrictions on app distribution and payments limited competition. Under the new rules, developers can offer third-party payment methods within their apps alongside Apple's own system. The fee structure varies: purchases through Apple's system remain subject to a 10% or 25% commission plus a 5% transaction fee. Apps that include a clickable link to external payment will face a 15% fee, while static text directing users elsewhere incurs no charge. Third-party app stores will pay a 5% Core Technology Commission. Read more of this story at Slashdot.

  • Fake MAS Windows Activation Domain Used To Spread PowerShell Malware
    by msmash on 25/12/2025 at 9:00 pm

    An anonymous reader shares a report: A typosquatted domain impersonating the Microsoft Activation Scripts (MAS) tool was used to distribute malicious PowerShell scripts that infect Windows systems with the 'Cosmali Loader'. BleepingComputer has found that multiple MAS users began reporting on Reddit yesterday that they received pop-up warnings on their systems about a Cosmali Loader infection. Based on the reports, attackers have set up a look-alike domain, "get[dot]activate[dot]win," which closely resembles the legitimate one listed in the official MAS activation instructions, "get[dot]activated[dot]win." Given that the difference between the two is a single character ("d"), the attackers bet on users mistyping the domain. Read more of this story at Slashdot.

  • Wall Street Has Stopped Rewarding 'Strategic' Layoffs
    by msmash on 25/12/2025 at 7:01 pm

    Goldman Sachs analysts have identified a notable shift in how investors respond to corporate layoff announcements, finding that even job cuts attributed to automation and AI-driven restructuring are now causing stock prices to fall rather than rise. The investment bank linked recent layoff announcements to public companies' earnings reports and stock market data, concluding that stocks dropped by an average of 2% following such announcements, and companies citing restructurings faced even harsher punishment. The traditional Wall Street playbook held that layoffs tied to strategic restructuring would boost stock prices, while cuts driven by declining sales would hurt them. That distinction appears to have collapsed. Goldman's analysts suggest investors simply don't believe what companies are saying -- firms announcing layoffs have experienced higher capex, debt and interest expense growth alongside lower profit growth compared to industry peers this year. The real driver, analysts suspect, may be cost reduction to offset rising interest expenses and declining profitability rather than any forward-looking efficiency play. Goldman expects layoffs to keep rising, motivated in part by companies' stated desire to use AI to reduce labor costs. Read more of this story at Slashdot.
