Software Design Is Knowledge Building: A Case Study

A company outsourced its integration service to a SaaS provider, then decided to build an in-house replacement, SVC, due to cost concerns. A highly skilled engineer, X10, independently completed SVC's development. However, subsequent teams struggled to maintain and modify the system, experiencing extremely low efficiency. The article analyzes the reason: the output of software development is not code, but the engineers' understanding of the system and its business logic—a 'theory'. After X10 left, the team lacked this 'theory', leading to difficulties in system maintenance, making it like a 'haunted house'. The author argues that software design should focus on knowledge building to facilitate understanding and maintenance by subsequent teams, avoiding the creation of 'legacy systems'.

Runtime Resizable Structs in Zig

2025-07-27

This post proposes the concept of a "runtime resizable struct" in the Zig programming language. Existing methods for handling structs with runtime-determined field lengths are cumbersome, requiring manual size calculations, memory allocation, and alignment considerations. The author presents a solution leveraging Zig's compile-time metaprogramming capabilities. Using `ResizableArray` and `ResizableStruct`, a runtime-resizable struct is implemented, simplifying operations and avoiding potential errors. The core is compile-time offset and size calculations, providing `init`, `get`, `resize`, and `deinit` methods for memory management. A minimal implementation is available on GitHub, with community feedback encouraged.

Mercantilism: The Rise and Fall of a Nationalistic Economic Policy

Mercantilism: The Rise and Fall of a Nationalistic Economic Policy

From the 16th to the 19th centuries, mercantilism dominated European economic thought. This nationalist policy prioritized maximizing exports and minimizing imports to accumulate national wealth and power. High tariffs, trade monopolies, and colonial expansion were hallmarks of this system. Mercantilism fueled competition and warfare between nations, and also propelled imperial expansion. However, its zero-sum game nature and restrictions on free trade ultimately led to its decline. Adam Smith's *The Wealth of Nations* delivered a powerful critique, paving the way for free trade. Though largely obsolete, echoes of mercantilist strategies, such as protectionism, persist in modern economic policy.

Debouncing in Programming: Efficiently Handling User Input

Debouncing in Programming: Efficiently Handling User Input

In programming, debouncing is a technique used to handle frequent events, such as continuous user input. It discards operations that occur too closely together within a specified time interval, consolidating them into a single invocation to prevent UI lag. For example, when a user types a search query, debouncing waits for a pause before executing the search, improving efficiency and user experience. Similar to throttling, but unlike throttling which limits the frequency of continuous operations, debouncing waits for a period of inactivity before acting.
