  • 'Why I Quit Streaming And Got Back Into Cassettes'
    by BeauHD on 25/12/2025 at 1:25 am

    "In the age of Spotify and AI slop, tapes remind us what we're missing when we stop taking risks," writes author Janus Rose in an article for 404 Media. Here's an excerpt: There are lots of advantages to the cassette lifestyle. Unlike vinyl records, tapes are compact and super-portable, and unlike streaming, you never have to worry about a giant company suddenly taking them away from you. They can be easily duplicated, shared, and made into mixtapes using equipment you find in a junk shop. When I was a kid, the first music I ever owned were tapes I recorded from MTV with a Kids' Fisher Price tape recorder. I had no money, so I would listen to those tapes for hours, relishing every word Kim Gordon exhaled on my bootlegged copy of Sonic Youth's "Bull in the Heather." Just like back then, my rediscovery of cassettes has led me to start listening more intentionally and deeply, devoting more and more time to each record without the compulsion to hit "skip." Most of the cassettes I bought in Tokyo had music I probably never would have found or spent time with otherwise. Getting reacquainted with tapes made me realize how much has been lost in the streaming era. Over the past two decades, platforms like Spotify co-opted the model of peer-to-peer filesharing pioneered by Napster and BitTorrent into a fully captured ecosystem. But instead of sharing, this ecosystem was designed around screen addiction, surveillance, and instant gratification -- with corporate middlemen and big labels reaping all the profits. Streaming seeks to virtually eliminate what techies like to call "user friction," turning all creative works into a seamless and unlimited flow of data, pouring out of our devices like water from a digital faucet. Everything becomes "Content," flattened into aesthetic buckets and laser-targeted by "perfect fit" algorithms to feed our addictive impulses. Thus the act of listening to music is transformed from a practice of discovery and communication to a hyper-personalized mood board of machine-optimized "vibes." What we now call "AI Slop" is just a novel and more cynically efficient vessel for this same process. Slop removes human beings as both author and subject, reducing us to raw impulses -- a digital lubricant for maximizing viral throughput. Whether we love or hate AI Slop is irrelevant, because human consumers are not its intended beneficiaries. In the minds of CEOs like OpenAI's Sam Altman, we're simply components in a machine built to maintain and accelerate information flows, in order to create value for an insatiably wealthy investor class. [...] Tapes and other physical media aren't a magic miracle cure for late-stage capitalism. But they can help us slow down and remember what makes us human. Tapes make music-listening into an intentional practice that encourages us to spend time connecting with the art, instead of frantically vibe-surfing for something that suits our mood from moment-to-moment. They reject the idea that the point of discovering and listening to music is finding the optimal collection of stimuli to produce good brain chemicals. More importantly, physical media reminds us that nothing good is possible if we refuse to take risks. You might find the most mediocre indie band imaginable. Or you might discover something that changes you forever. Nothing will happen if you play it safe and outsource all of your experiences to a content machine designed to make rich people richer.

  • Apple To Allow Alternative App Stores For iOS Users In Brazil
    by BeauHD on 25/12/2025 at 12:45 am

    Apple will allow alternative iOS app stores and external payment systems in Brazil after settling an antitrust case with the country's competition authority, following a lawsuit brought by MercadoLibre back in 2022. Thurrott reports: Yesterday, Brazil's Conselho Administrativo de Defesa Economica (CADE) explained in its press release that it has approved a Term of Commitment to Cease (TCC) submitted by Apple. To settle the lawsuit, the iPhone maker has agreed to allow third-party iOS app stores in Brazil and to let developers use external payment systems. The company will also use neutral wording in the warning messages about third-party app stores and external payment systems that iOS users in Brazil will see. As part of the settlement, Apple has 105 days to implement these changes to avoid a fine of up to $27.1 million. A separate report from Brazilian blog Tecnoblog revealed that Apple will still take a 5% "Core Technology Commission" fee on transactions going through alternative app stores. Additionally, the company will take a 15% cut on in-app purchases for App Store apps when developers redirect users to their own payment systems. Read more of this story at Slashdot.

  • Apple's App Course Runs $20,000 a Student. Is It Really Worth It?
    by BeauHD on 25/12/2025 at 12:02 am

    An anonymous reader quotes a report from Wired: Two years ago, Lizmary Fernandez took a detour from studying to be an immigration attorney to join a free Apple course for making iPhone apps. The Apple Developer Academy in Detroit launched as part of the company's $200 million response to the Black Lives Matter protests and aims to expand opportunities for people of color in the country's poorest big city. But Fernandez found the program's cost-of-living stipend lacking -- "A lot of us got on food stamps," she says -- and the coursework insufficient for landing a coding job. "I didn't have the experience or portfolio," says the 25-year-old, who is now a flight attendant and preparing to apply to law school. "Coding is not something I got back to." Since 2021, the academy has welcomed over 1,700 students, a racially diverse mix with varying levels of tech literacy and financial flexibility. About 600 students, including Fernandez, have completed its 10-month course of half-days at Michigan State University, which cosponsors the Apple-branded and Apple-focused program. WIRED reviewed contracts and budgets and spoke with officials and graduates for the first in-depth examination of the nearly $30 million invested in the academy over the past four years -- almost 30 percent of which came from Michigan taxpayers and the university's regular students. As tech giants begin pouring billions of dollars into AI-related job training courses across the country, the Apple academy offers lessons on the challenges of uplifting diverse communities. [...] The program gives out iPhones and MacBooks and spends an estimated $20,000 per student, nearly twice as much as state and local governments budget for community colleges. [...] About 70 percent of students graduate, which [Sarah Gretter, the academy leader for Michigan State] describes as higher than typical for adult education. She says the goal is for them to take "a next step," whether a job or more courses. Roughly a third of participants are under 25, and virtually all of them pursue further schooling. [...] About 71 percent of graduates from the last two years went onto full-time jobs across a variety of industries, according to academy officials. Amy J. Ko, a University of Washington computer scientist who researches computing education, calls under 80 percent typical for the coding schools she has studied but notes that one of her department's own undergraduate programs has a 95 percent job placement rate.

  • The Phone-Based Retirement Is Here
    by msmash on 24/12/2025 at 11:20 pm

    Adult children across the United States are increasingly reporting that their aging parents have developed what looks remarkably like the smartphone addiction [non-paywalled source] typically associated with teenagers, a phenomenon The Atlantic's Charlie Warzel has dubbed "phone-based retirement." A 2019 Pew Research Center study found people 60 and older spend more than half their daily leisure time -- four hours and 16 minutes -- in front of screens. Nielsen reported this year that adults 65 and up watch YouTube on their TVs nearly twice as much as they did two years ago. 40% of adults aged 59 to 77 reported feeling anxious without device access in a 2,000-person survey. Ipsit Vahia, chief of geriatric psychiatry at Mass General Brigham's McLean Hospital, cautioned against treating all older adults as a monolithic group. The COVID-19 pandemic drove significant tech adoption among seniors as Zoom became essential for family gatherings, church services, and telehealth. Some research suggests device use may be linked to better cognitive function for people over 50, and Vahia noted that technology use in older adults appears to protect them from isolation and loneliness -- the opposite of its effect on teenagers.

  • Spotify Disables Accounts After Open-Source Group Scrapes 86 Million Songs From Platform
    by BeauHD on 24/12/2025 at 10:40 pm

    After Anna's Archive published a massive scrape containing 86 million songs and metadata from Spotify, the streaming giant responded by disabling the nefarious accounts responsible. A spokesperson for Spotify told Recorded Future News that it "has identified and disabled the nefarious user accounts that engaged in unlawful scraping." "We've implemented new safeguards for these types of anti-copyright attacks and are actively monitoring for suspicious behavior," the spokesperson said. "Since day one, we have stood with the artist community against piracy, and we are actively working with our industry partners to protect creators and defend their rights." The Record reports: The spokesperson added that Anna's Archive did not contact them before publishing the files. They also said it did not consider the incident a "hack" of Spotify. The people behind the leaked database systematically violated Spotify's terms by stream-ripping some of the music from the platform over a period of months, a spokesperson said. They did this through user accounts set up by a third party and not by accessing Spotify's business systems, they added. Anna's Archive published a blog post about the cache this weekend, writing that while it typically focuses its efforts on text, its mission to preserve humanity's knowledge and culture "doesn't distinguish among media types." "Sometimes an opportunity comes along outside of text. This is such a case. A while ago, we discovered a way to scrape Spotify at scale. We saw a role for us here to build a music archive primarily aimed at preservation," they said. "This Spotify scrape is our humble attempt to start such a 'preservation archive' for music. Of course Spotify doesn't have all the music in the world, but it's a great start." Read more of this story at Slashdot.

  • Microsoft Says It's Not Planning To Use AI To Rewrite Windows From C To Rust
    by msmash on 24/12/2025 at 10:02 pm

    Microsoft has denied any plans to rewrite Windows 11 using AI and Rust after a LinkedIn post from one of its top-level engineers sparked a wave of online backlash by claiming the company's goal was to "eliminate every line of C and C++ from Microsoft by 2030." Galen Hunt, a principal software engineer responsible for several large-scale research projects at Microsoft, made the claim in what was originally a hiring post for his team. His original wording described a "North Star" of "1 engineer, 1 month, 1 million lines of code" and outlined a strategy to "combine AI and Algorithms to rewrite Microsoft's largest codebases." The repeated use of "our" in the post led many to interpret it as an official company direction rather than a personal research ambition. Frank X. Shaw, Microsoft's head of communications, told Windows Latest that the company has no such plans. Hunt subsequently edited his LinkedIn post to clarify that "Windows is NOT being rewritten in Rust with AI" and that his team's work is a research project focused on building technology to enable language-to-language migration. He characterized the reaction as "speculative reading between the lines." Read more of this story at Slashdot.
