Arthur O’Dwyer discusses the origin of the term "calling" functions in programming, particularly in the context of C++. The term likely derives from the idea of "calling up" or "summoning" a subroutine, which relates to how one would "call for" a book from a closed-stack library. This usage is traced back to library terminology, with the Oxford English Dictionary (OED) citing its first library-related use in 1876 by Melvil Dewey. The

The content discusses the functionality and benefits of the garbage collector (GC) in the Common Language Runtime (CLR), which acts as an automatic memory manager for applications. It allows developers to avoid manual memory management tasks, reducing the risk of memory leaks and unsafe memory access. The GC efficiently allocates memory on the managed heap, reclaims unused objects, and ensures memory safety by preventing objects from using memory allocated for others. Additionally, it highlights key memory concepts, such as the separation of virtual address space for

The author reflects on their past experience developing a Sudoku solver using Poetry's dependency resolver, which was sold to EDB. With advancements in Python packaging, particularly the popularity of uv, they propose updating their approach by possibly using uv instead of Poetry to tackle a Wordle puzzle instead of Sudoku. In the previous method, Sudoku was represented with 81 Python packages, with version constraints to ensure that no two cells in the same row, column, or 3x3 square contained the same number. This

The Model Context Protocol (MCP) has become a standard for large language models (LLMs) to interact with external tools, adding new capabilities but also new risks. In this context, the content discusses an attack that exploits Supabase's MCP integration to access a developer’s private SQL tables. The core issue arises from LLMs' inability to distinguish between instructions and data; a carefully crafted user-provided input could be interpreted as an instruction, leading to unauthorized data exposure. To illustrate the vulnerability

TypeScript 5.9 Beta has been announced, now available via npm. This update revises the `tsconfig.json` file initialization process. Previously, using `tsc --init` would generate a comprehensive `tsconfig.json` with many commented-out settings, which users often found cumbersome and would quickly delete. Feedback indicated that users better rely on editor auto-completion and online documentation for discovering options. To improve the user experience, TypeScript 5.9 will initialize with more practical settings

In a recent blog post, the reality of the software development landscape in 2025 is examined, particularly in light of the rise of AI in coding. While there is a notion that AI will transform all developers into highly efficient "10x developers," the experience of CTOs and engineering leaders suggests otherwise. They face challenges with AI-generated code that is often flawed despite appearing perfect, leading to an increased demand for critical thinking skills in developers. Engineering leaders prioritize individuals who can critically assess and validate AI

The post argues that C can be used for object-oriented programming (OOP) despite lacking inheritance and polymorphism as explicit features. It suggests that OOP is more about structuring solutions than the specific language features. The author intends to demonstrate how to implement inheritance and polymorphism in C using structures and functions, which will showcase how dynamic languages operate under the surface. The discussion includes a comparison with C++ where inheritance allows a type (like Square) to extend another (like Shape), inheriting its
