Preferring Throwaway Code Over Design Docs: A More Efficient Software Development Approach

Preferring Throwaway Code Over Design Docs: A More Efficient Software Development Approach

In software development, the traditional design document and incremental development model isn't always efficient. Author Doug Turnbull proposes a "coding binge" approach: quickly implement a prototype using a temporary PR, get early team feedback, refine the design, and then gradually break it down into deployable PRs. This method encourages rapid iteration, early problem detection, and considers code itself as the best documentation. While design documents still have value in specific situations, the author advocates for "showing, not telling," using code prototypes for rapid validation and iteration to achieve more efficient software development.

Sensirion SGP41 TVOC Sensor Accuracy Test: Relative Changes, Not Absolute Values

AirGradient conducted accuracy and precision tests on the Sensirion SGP41 TVOC sensor used in their air quality monitors. The tests revealed that the sensor effectively tracks relative changes in TVOC levels – detecting increases or decreases – but cannot provide precise absolute values. This is due to limitations inherent in low-cost VOC sensors, including lack of specificity, cross-sensitivity, environmental sensitivity, and baseline drift. While the sensor cannot precisely measure TVOC concentrations, it still offers practical value in identifying TVOC sources and for environmental monitoring. Future testing by AirGradient will explore sensor performance under various conditions to further understand its capabilities and limitations.

Literary Review: The Achievements and Limitations of the 20th-Century Novel

Edwin Frank's new book, *Stranger Than Fiction: Lives of the Twentieth-Century Novel*, explores the accomplishments of the 20th-century novel. Frank argues that novels, through formal innovations like Kafka's rambling sentences and Stein's repetitions, guide readers to slow down and savor the nuances of language. He praises novelists' efforts in expressing collective experiences, particularly the horrors of war and the awakening of self-awareness, but also points out the book's Eurocentric perspective, its insufficient attention to novels from other cultural backgrounds, and its somewhat superficial exploration of war and self-awareness.

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.
