Philosophical Dead Ends in Evolutionary Theory

This review examines Richard Dawkins's "The Genetic Book of the Dead" and Sara Imari Walker's "Life as No One Knows It." Dawkins continues his "selfish gene" theory, arguing that genes are the central driving force of evolution. However, the review points out that this view is outdated and fails to adequately consider factors such as development, epigenetics, and niche construction. Walker's book attempts to explain the origin of life from the perspective of assembly theory, but the review argues that it is overly simplistic and fails to fully clarify the essence of life. The article concludes that popular science books often tend towards simplistic narratives, ignoring the complexity and diversity of the field of biology.

Programmer Focus Indicator: The Birth of FlowLight

2024-12-15

Inspired by a research paper on the impact of work interruptions, programmer Shae Erisson DIYed a system called FlowLight to indicate whether a programmer is in a focused "flow" state. The system monitors idle time in the Emacs editor; when the programmer is inactive for a period, an Adafruit MagTag board's LED changes color (green for idle, red for busy). Erisson also wrote an HTTP server in CircuitPython to remotely control the LED color and display status. While the system has room for improvement, such as more granular idle time monitoring and a more visually appealing display, it effectively helps programmers avoid interruptions and improve productivity.

Entropy: A Rethink of Disorder in the Universe

Two hundred years ago, French engineer Sadi Carnot introduced the concept of entropy to quantify the universe's irreversible slide into decay. However, modern physics views entropy not simply as 'disorder,' but as a reflection of an observer's limited knowledge of a system. This new perspective illuminates the deep connection between information and energy, driving technological advancements at the nanoscale. From Carnot's steam engine to modern information engines, the concept of entropy continues to evolve, helping us understand the universe's workings and prompting us to rethink the purpose of science and our place within it.
