Dark Mode's Energy-Saving Myth Busted: BBC Research Reveals Unexpected Findings

Contrary to popular belief, using dark mode on apps and websites may not save energy. A BBC Research & Development study found that users often increase screen brightness when using dark mode, negating its potential energy savings and potentially increasing consumption. In their experiment, 80% of participants boosted brightness in dark mode. Furthermore, website responsiveness and data transfer showed little correlation with energy usage. The researchers conclude that relying solely on dark mode or website optimization for energy efficiency is misguided; lowering screen brightness is a more effective approach.

Intel's 18A Arm SoC: A Hail Mary to Attract Foundry Customers?

Intel showcased a reference Arm-based SoC, "Deer Creek Falls," built on its 18A process. This chip features a tiered CPU core configuration similar to Qualcomm's Snapdragon chips, aiming to attract external customers, particularly within the Arm ecosystem. Intel Foundry is reportedly struggling to secure clients and may halt development of its 14A and future nodes without more. The video also revealed performance optimization tools, countering previous rumors of their absence. While 18A is closed to external customers, this SoC might demonstrate Intel's 14A readiness, potentially luring major players like Apple and NVIDIA.

Elecom's Na Plus: First Consumer Sodium-Ion Power Bank is Here (But It's Bulky)

Accessory maker Elecom has launched the Na Plus, the first consumer-ready power bank using sodium-ion batteries. Boasting superior environmental friendliness, extreme temperature tolerance, and a claimed lifespan of nearly 5,000 charges, it promises long-term durability. However, the 9,000mAh Na Plus, priced at ~$67, is significantly larger and heavier than comparable lithium-ion alternatives, offering less power output (max 45W). While sodium-ion technology is still nascent, its eco-friendly and safer nature makes it a promising long-term solution, with potential for future cost and size reductions.

Musk's DOGE Agency Faces Racism Scandal and Data Security Concerns

Elon Musk's Department of Government Efficiency (DOGE) is embroiled in controversy over allegations of racism and unauthorized access to sensitive government data. A key employee with access to the Treasury Department's payment system resigned following the surfacing of racist social media posts. While DOGE claims its mission is to improve government efficiency, its actions have sparked outrage from Democrats and unions who argue its access to Treasury and Office of Personnel Management data poses significant security risks and conflicts of interest. Court intervention has limited DOGE's access, but the controversy continues, raising serious questions about the legality and transparency of its operations.

ChatGPT and the Future of Writing Instruction: A Debate on Values

The release of ChatGPT sparked a fervent discussion about writing instruction. The author, a writing pedagogy expert, has long advocated for changing traditional approaches, arguing that they overemphasize form over the essence of writing: expression and exploration. While ChatGPT generates fluent text, it lacks understanding of meaning and context, essentially functioning as a 'bullshitter'. The author contends ChatGPT doesn't create a new problem but exposes flaws in the current educational system. He calls for pedagogical reform, emphasizing the writing process over the final product, fostering critical thinking and creativity, and enabling students to genuinely experience the joy and value of writing.

Bering Land Bridge Was More Swamp Than Steppe, Study Finds

Bering Land Bridge Was More Swamp Than Steppe, Study Finds

New research challenges the long-held assumption that the Bering Land Bridge, the ancient landmass connecting Siberia and Alaska, was a dry grassland. Using sonar and sediment cores, scientists have revealed a much wetter landscape, more akin to a swampy ecosystem with numerous rivers and lakes. This discovery complicates theories of human and animal migration across the bridge, as the watery terrain would have posed different challenges and opportunities for various species. Interestingly, mammoth DNA was found in the sediment, indicating that even in this marshy environment, large animals could thrive and traverse the area. This research offers a revised perspective on how ancient humans populated North America.

80-Year-Old Crafts Retailer Joann to Liquidate All Stores

Joann Inc., an 80-year-old fabric and crafts retailer, is going out of business and closing all its stores after failing to overcome operational challenges. The company, which filed for Chapter 11 bankruptcy twice in less than a year, cited weak consumer demand and inventory issues. Despite initially vowing to stay open, Joann ultimately accepted a bid from GA Group to liquidate its assets, leading to going-out-of-business sales at all locations. While the website and app will remain operational for the time being, the closure of all stores marks the end of an era for the long-standing retailer.

FDA Approves Novel Analgesic, Challenging Opioid Dominance?

FDA Approves Novel Analgesic, Challenging Opioid Dominance?

The FDA has approved Vertex Pharmaceuticals' Journavx, a new pain medication designed to eliminate the risks of addiction and overdose associated with opioids. Journavx works differently than opioids, blocking proteins that trigger pain signals before they reach the brain. Trials showed it was more effective than a placebo, but not significantly better than a common opioid-acetaminophen combination. Despite its high cost ($15.50 per pill), its non-opioid mechanism and potential offer a significant step in combating the opioid crisis. However, disappointing results in later-stage trials for chronic pain cast uncertainty on its future.

Trump 2.0 and the Ghost of McKinley: American Imperialism Revisited

This article explores the policy legacy of President William McKinley and its influence on the Trump administration. McKinley's presidency saw the rise of the US as a global superpower, and his protectionist, expansionist, and imperialist policies bear a striking resemblance to Trump's 'America First' strategy. The article analyzes the economic boom, territorial expansion, and racial ideologies of McKinley's era, comparing them to the policy goals of the Trump administration. Both prioritize American economic interests and global hegemony while downplaying international cooperation and human rights. While acknowledging differences, the article concludes that the Trump administration's policy direction echoes McKinley's 'America First' ideology, with profound implications for the future global landscape.

Ants' Traffic-Flow Secrets Could Untangle Future Self-Driving Car Gridlock

Researchers studying ant foraging trails have discovered how these insects avoid traffic jams, even at high densities. Ants maintain a nearly constant speed and distance between groups, avoiding overtaking. This cooperative behavior offers a potential solution for programming self-driving cars. By sharing information and coordinating speed and spacing, autonomous vehicles could mimic ants' efficient traffic flow, reducing congestion. While self-driving cars can't climb walls like ants, learning from their 'don't tailgate' strategy could significantly improve human-driven traffic flow.

Unraveling the PPG Wave 2.2 & 2.3: An 8-bit vs. 12-bit DAC Mystery

2024-12-15

This article delves into the subtle yet significant differences between the PPG Wave 2.2 and 2.3 synthesizers. While the 2.3 utilizes 12-bit DACs, wavetable playback remains 8-bit; only samples imported via external devices fully leverage the 12-bit precision. Oscilloscope measurements reveal a unique audio processing method: two oscillators send data interleaved, resulting in a DAC output frequency double the individual oscillator sample rate. This creates a distinctive timbre and high-frequency aliasing beyond human hearing. The article also notes the relatively slow CV update rate, yet the sound retains its character.

PHP Compile-Time Generics: A Pragmatic Compromise

Generics have long been a sought-after feature for PHP, but runtime implementation has proven incredibly difficult. The PHP Foundation team proposes a different approach: compile-time generics limited to interfaces and abstract classes. This offers most of the benefits of generics while avoiding many pitfalls. By performing type checking at compile time, it significantly improves efficiency and reduces errors. While runtime generics remain impossible with this approach, it represents a substantial improvement, warranting serious community consideration.
