Code Rewrites: Magic Wand vs. Iterative Improvement

2025-01-03

This article explores the pros and cons of code rewrites. Using Netscape's failure as an example, the author argues that rewriting isn't always the best approach. Instead of large-scale rewrites, maintain idealism, imagine a perfect solution (wave a magic wand), and then iteratively improve the existing code. By distinguishing between necessary and accidental complexity, identify improvement directions and continually reflect on "If I could wave a magic wand, what would I want it to be?", ultimately reaching the ideal state.

Gorbachev's Reforms: A Helpless or Reckless Revolution?

This essay examines the reasons for the failure of Gorbachev's reforms, particularly the role of entrenched interests in the demise of the USSR. It compares two contrasting narratives: the "helpless" narrative, which argues that Gorbachev lacked power and was obstructed by powerful bureaucratic interests; and the "reckless" narrative, which contends that Gorbachev possessed significant power but pursued reckless reforms, especially the lack of crucial price reform, ultimately leading to the collapse of the USSR. By analyzing Gorbachev's power, personnel changes, and economic reforms, and by reinterpreting the coup against Khrushchev, the essay supports the "reckless" narrative, suggesting that Gorbachev's idealism and disregard for institutions were the primary causes of the USSR's collapse.

Visual Programming's Future: Beyond Nodes and Wires

This article explores the limitations of visual programming, arguing that it has long been trapped in the node-and-wire paradigm, neglecting the principle of "form follows function." Using CellPond as an example, the author highlights that its success lies in defining the underlying function (only four operations) first, with the form emerging naturally. The author further elaborates on the threefold meaning of "function": intrinsic nature, rationality, and algebra, and argues that visual programming should focus on leveraging the human visual cortex's pattern recognition capabilities to model problems, rather than simply mimicking textual programming. The article proposes modeling problems as entities and relationships, and utilizing visual elements (color, grouping, motion) to represent state changes, thus breaking through the limitations of existing visual programming and creating more powerful programming tools.
