Supercritical CO2 Circuit Breaker: A Green Alternative to SF6

2025-06-15

Supercritical CO2 Circuit Breaker: A Green Alternative to SF6

Researchers at Georgia Tech are testing a novel high-voltage circuit breaker that uses supercritical carbon dioxide fluid to replace the environmentally damaging sulfur hexafluoride (SF6). SF6 is nearly 25,000 times more potent as a greenhouse gas than carbon dioxide, and this new breaker promises to significantly reduce greenhouse gas emissions in power systems. The team overcame challenges in maintaining supercritical CO2 under high pressure, developing crucial components independently. If successful, this could provide a strong solution for the eco-friendly upgrade of millions of high-voltage circuit breakers globally, although it requires some auxiliary equipment like heat pumps. Meanwhile, GE Vernova has also developed circuit breakers using alternative gas mixtures, which, while still containing a small amount of fluorinated gas, have significantly reduced greenhouse effects. Ultimately, solid-state semiconductor circuit breakers promise faster and greener switching, but are still in early development.

Meta's Llama 3.1 Model Found to Memorize Significant Portions of Copyrighted Books

New research reveals Meta's Llama 3.1 70B large language model surprisingly memorized substantial portions of copyrighted books, memorizing 42% of Harry Potter and the Sorcerer's Stone. This is significantly higher than its predecessor, Llama 1 65B, raising serious copyright concerns. Researchers efficiently assessed the model's 'memorization' by calculating the probability of generating specific text sequences, rather than generating a large volume of text. This finding could significantly impact copyright lawsuits against Meta and might prompt courts to revisit the boundaries of fair use in AI model training. While the model memorized less from obscure books, the excessive memorization of popular books highlights challenges in large language models concerning copyright issues.

The Secret Code of Hobos: A Lost Cultural Heritage

2025-06-15

The Secret Code of Hobos: A Lost Cultural Heritage

The 'hobo' culture of early 20th-century America was far more complex than we often imagine. They weren't simply homeless individuals, but a group with a unique culture and secret communication system. They used a special symbolic language—the 'hobo code'—leaving markings on walls, water towers, and other surfaces to indicate food, shelter, and danger. While the extent of this code's use is debated, it symbolizes the unique ways hobos created to survive and help each other, and its legacy can be seen in later cultural phenomena like graffiti art.

The Mystery of Bob Ross's Missing Masterpieces

Bob Ross, the beloved painter known for his soothing voice and happy little trees, created nearly 30,000 paintings during his lifetime—far more than Picasso. Yet, his artwork rarely appears on the open market. This article investigates, revealing that a large portion is held by Bob Ross Inc., which prioritizes its IP rights over the paintings themselves. Others are privately owned, while some fetch high prices at auctions and in the secondary market. Bob Ross's own focus on the painting process rather than the finished product likely contributes to the scarcity of his works.

The Browser Wars Legacy: The Winding Road from SSL to TLS

2025-06-15

The Netscape/Microsoft browser wars of the mid-90s were incredibly fierce. Netscape's SSL protocol, flawed from the start, led to Microsoft's competing PCT protocol. To prevent Microsoft from controlling the standard, Netscape developed SSL 3.0. Eventually, through negotiations, the IETF standardized the protocol, renaming SSL 3.0 to TLS 1.0. This marked the end of the browser wars' impact on the standard, showcasing the compromises and competition inherent in tech standardization.

SumatraPDF Dev Ditches std::function After 16 Years, Rolls His Own

After 16 years of C++ development on SumatraPDF, the author abandoned `std::function` and lambdas due to debugging difficulties. Crash reports were hard to decipher because of the auto-generated names of compiler-generated lambda functions. He created simpler, custom callback functions `Func0` and `Func1`. While less feature-rich than `std::function`, they offer significant advantages in memory footprint and compilation speed, and are easier to debug. This post details the design and implementation of `Func0` and `Func1`, and explains why this approach better suits SumatraPDF's needs.

LLMs Took the Joy Out of Programming: A Programmer's Confession

2025-06-15

The author reflects on a shift in their programming habits. Once a 'journey programmer,' passionate about learning and problem-solving, they've become increasingly reliant on Large Language Models (LLMs) for code generation, transforming into a more 'destination-oriented' programmer. While LLMs boost efficiency, they've reduced the time spent learning and thinking, diminishing the author's enjoyment of programming. This shift is attributed to several factors, including a preference for building useful projects and over-reliance on LLMs. The author hopes to lessen their dependence on LLMs and rediscover the joy of the programming process.

US Ethanol Policy: An Environmental and Economic Failure?

A new report sharply criticizes long-standing US policies supporting biofuel production. It argues that corn-based ethanol production has led to economic and social imbalances in rural communities and increased greenhouse gas emissions, contrary to purported climate benefits. The report also finds ethanol policies have displaced food crops, resulted in inefficient land use, and caused water pollution and wildlife habitat destruction. While the biofuels industry and politicians have long claimed ethanol is vital to the rural economy, mounting research suggests the benefits are overstated and the environmental costs far outweigh the gains. New policies could further expand production, exacerbating these issues.
