Nvidia Sells RTX 5080/5090 GPUs From a Food Truck at GTC

2025-03-20

Nvidia is selling its highly sought-after RTX 5080 and 5090 graphics cards from a pop-up food truck at its GPU Technology Conference (GTC). Only available to GTC attendees, the limited stock (1000 of each model) is sold in small batches at unpredictable times. While primarily targeting developers and professionals, the scarcity and high demand likely mean some cards will quickly reappear on resale markets.

Critical macOS Flaw Leaks Passwords and iCloud Data via NetAuthAgent

2025-03-20

A security research article exposes a critical vulnerability in macOS (CVE-2024-54471) allowing attackers to steal file server credentials and even iCloud account information and API tokens via NetAuthAgent. The vulnerability stems from NetAuthAgent's MIG server failing to verify message senders, enabling attackers to send malicious messages to retrieve keychain credentials, subsequently accessing iCloud data including contacts, calendars, and location. The article details the Mach kernel, MIG mechanism, and exploitation process, urging users to update macOS to the latest version and enable Advanced Data Protection.

LED Efficiency Surpasses 100%: A Low-Voltage Breakthrough

2025-03-20

MIT researchers have demonstrated, for the first time, an LED that emits more optical power than it consumes, achieving an efficiency of 230%. The key is drastically reducing the applied voltage to 30 picowatts, where LED efficiency increases as output power decreases. While currently limited to low-power, dim LEDs, this breakthrough leverages excess heat from atomic lattice vibrations, opening new avenues for highly efficient electromagnetic communication and novel solid-state cooling technologies. It challenges the conventional understanding of LED efficiency being inversely proportional to brightness.

LLMs and AI: Scraping the Web Dry

2025-03-20

LLM and AI companies are aggressively scraping data from the web, targeting everything from large websites to small project forges like the GNOME GitLab server. This unchecked scraping is overwhelming servers and creating significant financial burdens and security risks for website owners. The author urges website owners to set billing limits to avoid unexpected costs and condemns the irresponsible actions of these companies. The question is raised: how long until personal websites and services like Mastodon become targets?

Ancient Galaxy's Oxygen Discovery Challenges Early Universe Theories

2025-03-20

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected oxygen in JADES-GS-z14-0, the most distant galaxy ever confirmed. Light from this galaxy traveled 13.4 billion years to reach us, showing it as it was when the universe was just 300 million years old. The surprising discovery of significant amounts of oxygen, a heavy element, suggests the galaxy is far more chemically mature than expected—a 'teenager' instead of an 'infant.' This challenges prevailing theories about galaxy formation in the early universe and prompts a rethink of how rapidly galaxies evolved.

Tesla Recalls Entire Cybertruck Fleet: Falling Trim Pieces Force Massive Recall

2025-03-20

Tesla has issued a recall for all 46,096 Cybertrucks produced between November 2023 and February 2025. The recall addresses a faulty adhesive causing stainless steel roof trim panels to detach while driving. Owners must bring their vehicles to dealerships for repairs involving a stronger adhesive and reinforcement. This marks the eighth recall for the Cybertruck since deliveries began in 2023, although previous recalls were often software-based. This one requires physical intervention.

The Rise of Solar PV: A Cheap Energy Future?

2025-03-20

This article explores the rapid growth of solar photovoltaic (PV) power generation and its future potential. While currently accounting for only around 4% of total US electricity generation, the cost of solar PV has fallen nearly ten thousandfold in the last 70 years and is projected to fall further. However, the intermittency of solar power is a major challenge, as it cannot generate electricity on demand. The article uses simulations to explore strategies for addressing intermittency by increasing solar panel capacity and energy storage systems. It concludes that as solar and storage costs continue to decline, "overbuilding" to meet a larger fraction of electricity demand will become economically feasible. Ultimately, solar's low and declining costs make it a competitive energy option, but its intermittency remains a challenge to overcome.

Dutch Parliament Votes to Ditch US Tech, Prioritize National Sovereignty

2025-03-20

The Dutch parliament unanimously passed eight motions urging the government to replace US-made technology with homegrown alternatives. Driven by concerns about data sovereignty and the potential for US tech giants to exert political pressure, the motions call for a range of actions, including halting migrations to American cloud services, creating a Dutch national cloud, and repatriating the .nl top-level domain. MP Barbara Kathmann argued that over-reliance on US tech weakens the Netherlands' digital sovereignty and expertise. While non-binding, the overwhelming support for these motions puts significant pressure on the government to act, potentially setting a precedent for other European nations.

The EU, citing the Digital Markets Act (DMA), is forcing Apple to open nine iOS connectivity features to boost interoperability and break Apple's closed ecosystem. Apple counters that this is anti-innovative, harms user privacy and security, and restricts its innovation in Europe. Smaller companies support the EU's decision, arguing that Apple's actions stifle competition, leading to higher prices and reduced innovation. The core of this debate is how to balance the innovative drive of large tech companies with the need to foster market competition.

Two independent teams of cosmologists have recently found evidence suggesting dark energy, the mysterious force accelerating the universe's expansion, might be weakening. This contradicts previous models and is based on observations of millions of galaxies. The reliability of this finding increases with the growing amount of data. If confirmed, this discovery would revolutionize our understanding of the universe's ultimate fate, potentially requiring revisions to Einstein's theory of gravity or the introduction of new physics. It challenges the prevailing idea that dark energy is the energy of space itself, hinting at the possibility of unknown components or particles in the cosmos.
