Spotify's Shady Secret: Fake Artists and Inflated Play Counts Exposed

2024-12-21

A year-long investigation reveals Spotify's deceptive practices. A program called "Perfect Fit Content" (PFC) involves partnerships with production companies to create and promote fake artists and tracks, artificially inflating play counts to reduce royalty costs and boost profits. These fake tracks, often ambient, classical, electronic, jazz, or lo-fi, are strategically placed in playlists designed for background listening. The Spotify CEO's significant stock sales around the time of the revelations further fueled controversy. This scandal raises serious concerns about transparency and fairness in the music industry, prompting calls for congressional investigation and a more transparent music streaming ecosystem.

Qualcomm Wins Arm Licensing Dispute

2024-12-21

A Delaware jury ruled in favor of Qualcomm Inc. in its legal battle with Arm Holdings Plc, finding that Qualcomm did not breach a license agreement for chip technology acquired through its $1.4 billion purchase of Nuvia Inc. in 2021. Arm claimed Qualcomm used the technology without paying higher licensing fees. While the jury found Qualcomm didn't violate the agreement, they couldn't reach a verdict on whether Nuvia itself breached the license, leaving that question open for a later retrial. The ruling is significant for Qualcomm's position in the mobile chip market.

The Winkel Tower: A Unique WWII Air Defense Structure

2024-12-21

In the early 1930s, German architect Leo Winkel designed a unique above-ground air raid shelter, the Winkel Tower. Unlike traditional underground bunkers, its sloped roof was designed to deflect bombs, minimizing the risk of explosion. This innovative design significantly reduced construction costs and time, while the ground-level detonation allowed for pressure wave dissipation. Patented in 1934, approximately 200 Winkel Towers were built throughout Germany during WWII. Many preserved towers now enjoy monument protection.

Google strongly disagrees with and will appeal the Department of Justice's (DOJ) ruling in the search distribution lawsuit. Ahead of an April 2025 hearing, Google submitted its own remedies proposal, focusing on contracts with browser and Android device makers. The proposal aims to give browser companies and device makers more flexibility in choosing default search engines, while ensuring compliance with the court's order and avoiding harm to consumer privacy and US tech leadership. In contrast, the DOJ's proposal is seen as overly interventionist and potentially harmful to consumers and US tech competitiveness.

UK Electricity Bills Soar: High Subsidies and Grid Investment Lag

2024-12-20

High UK electricity bills aren't solely due to wholesale power costs. A recent analysis reveals that network costs and green energy subsidies are major drivers. Twenty years of stagnant grid investment now necessitate urgent expansion, skyrocketing network costs. Contracts subsidizing renewables will continue increasing bills, while past subsidies, like the Renewables Obligation and Feed-in Tariff, failed to adjust quickly enough to falling renewable energy prices, locking in massive long-term costs. The author suggests reducing grid dependence or improving grid utilization as pathways to lower future electricity bills.

California Orders Uber to Fingerprint Drivers for Teen Rides

2024-12-20

The California Public Utilities Commission (CPUC) ruled that Uber must fingerprint drivers for its teen ride-hailing service, Uber for Teens, to continue operating in the state. This decision stems from safety concerns regarding unaccompanied minors. While Uber has historically resisted fingerprint-based background checks, the CPUC cited the importance of protecting children from potential sexual offenders. The ruling significantly impacts Uber's operations, while competitor HopSkipDrive, which already employs stricter safety measures including fingerprinting, supports the decision. The added cost of fingerprinting may lead to higher prices for Uber's teen ride service.

Tiny Black Holes May Have Left Tunnels in Earth's Rocks

2024-12-19

Scientists propose a bold hypothesis: primordial black holes, formed in the early universe, might have traversed Earth's rocks, leaving behind microscopic tunnels invisible to the naked eye. While these tunnels are minuscule, powerful microscopes might detect them, offering a potential pathway to discovering these elusive objects. Researchers suggest that searching for these tunnels, despite the low probability of success, could yield immense rewards. Furthermore, they hypothesize that primordial black holes might lurk inside certain planets, hollowing them out by consuming their liquid cores. This research offers a novel approach to finding primordial black holes, representing a significant step forward in exploring the origins of the universe.

Saturn's Rings: Older Than We Thought?

2024-12-19

A new study challenges the long-held belief that Saturn's rings are relatively young. Previous research, based on data from the Cassini spacecraft, suggested an age of only a few hundred million years. However, a team led by planetary scientist Ryuki Hyodo used computer simulations to show that micrometeoroid impacts on the rings produce far less contamination than previously thought. This implies the rings could be billions of years old, as old as Saturn itself, predating even the dinosaurs. This finding significantly alters our understanding of early solar system evolution and points towards future missions for more detailed investigation.
