This article walks readers through Git’s internal architecture, explaining the .git directory layout, object storage, staging area, and how low‑level commands like git hash-object, write‑tree, and commit‑tree build commits and branches.
This article explains why native pointers do not exist in Python, describes the underlying object model, immutable versus mutable objects, the distinction between variables and names, and demonstrates several practical ways to emulate pointer behavior using mutable containers, custom classes, and the ctypes module.
This article explains Python's memory management by exploring how objects are stored, how references and reference counting work, the role of the garbage collector, generational collection, and how reference cycles are detected and reclaimed.
This article explains Python’s core principle that everything is an object, detailing the distinction between type objects, instance objects, and metaclasses, how built‑in types like int and str fit into the hierarchy, the role of the object base class, variable naming as pointers, and the differences between mutable, immutable, fixed‑length and variable‑length objects.
This article systematically explores Git’s underlying architecture, detailing the lifecycle of objects, core data structures, packfile formats, indexing mechanisms, and the algorithms used for object retrieval, while providing practical command examples and visual diagrams to demystify Git’s storage and retrieval models.
This article explains how Swift objects are created and destroyed, how method calls are implemented compared with Objective‑C, the memory layout of Swift classes, the role of virtual tables, the impact of compiler optimizations, and the feasibility of runtime method replacement, illustrated with extensive C‑style pseudocode examples.
