Rivulet: A Flowing Strand Programming Language

Rivulet is a novel programming language that uses semigraphic characters representing 'strands' to write code. Programs consist of tightly packed code blocks called glyphs, each containing several types of strands that execute together. Rivulet avoids traditional control flow mechanisms, instead using a rollback mechanism to implement conditional branching and loops. Data is organized as lists, and commands operate on single cells or entire lists. While its syntax may seem complex at first glance, it's actually quite easy to learn.

Bhutan's Talking Stamps: A Surprising Investment Opportunity

Issued in 1972, Bhutan's miniature vinyl record stamps, playable on a standard turntable, were initially dismissed as novelties. These seven stamps, featuring Bhutanese folk songs and history, have recently surged in value due to their rediscovery by vinyl collectors. The stamps' creator, American adventurer Burt Todd, revolutionized Bhutan's philatelic program with innovative designs, transforming what were once cheap trinkets into a highly sought-after collector's item.

Goodbye Tedious Workflows: My tmux-Powered Dev Setup

2025-06-23

This post details a highly efficient development workflow built around tmux. The author uses clever tmux configuration and scripting to directly open files on a remote server, seamlessly jump between panes, and switch effortlessly between files—all without local clones. The post walks through the configuration, including regular expressions and scripts, and compares alternatives. The motivation stemmed from frustrations with VSCode's lag and keybinding conflicts. While complex to set up, the author argues the efficiency gains outweigh the cost.

OpenAI's Study Mode: A Sugar-Coated Approach to AI Education?

OpenAI's newly released "Study Mode" aims to assist learning by guiding users through interactive questioning and positive feedback, rather than providing direct answers. The author questions the effectiveness of this approach, arguing it may excessively cater to students, leading to reliance on AI instead of independent thought. Through experiments with various AI models, the author demonstrates that "Study Mode" encourages excessive praise and user-pleasing behavior, potentially negatively impacting learning and posing risks to vulnerable students. While acknowledging some benefits, the author emphasizes the potential of AI as a research tool over its over-reliance as an educational tool.

US Hit by Worst Flu Season in 15 Years

The US is experiencing its most intense winter virus season in 15 years, with a surge in flu activity leading to school closures and hospital overcrowding. CDC data reveals that the percentage of doctor visits for flu-like illnesses surpasses any peak since 2009-2010. While COVID-19 and RSV appear to be declining, the flu has already caused an estimated 24 million illnesses, 310,000 hospitalizations, and 13,000 deaths, including at least 57 children. 43 states report high or very high flu activity, with the South, Southwest, and West particularly hard hit. Despite recommendations for flu vaccination, adult coverage is only 44%, and even lower for children at 45%. The government hasn't yet released effectiveness data for this season's flu vaccine.

The AI Hype in Science: A Physicist's Disillusionment

Nick McGreivy, a Princeton PhD physicist, shares his experience applying AI to physics research. Initially optimistic about AI's potential to accelerate research, he found AI methods significantly underperformed their advertised capabilities. Many papers exaggerated AI's advantages, with issues like data leakage prevalent. He argues that the rapid rise of AI in science stems more from benefits to scientists (higher salaries, prestige) than genuine improvements to research efficiency. He calls for more rigorous AI evaluation and cautions against optimistic biases in AI research.

AI Writes Code, AI Reviews It? Is That Silly?

Daksh, co-founder of Greptile, discovered that an AI code generation tool, Devin, was submitting more pull requests than any human engineer. This raises the intriguing question: should AI-generated code be reviewed by AI itself? While LLMs are stateless, each call is independent, this doesn't mean AI perfectly reviews its own code. AI-generated code, while boosting efficiency, may introduce bugs humans struggle to find. Research shows AI is more effective than humans at finding certain types of bugs, although its accuracy still needs improvement. Ultimately, the article argues that while not perfect, AI code review is more effective than humans at finding specific bug types introduced by AI itself.
