Python Meta-Circular Interpreter: Implementing a Python Interpreter in Python

2024-12-18

This article demonstrates how to create a Python meta-circular interpreter (MCI) using Python itself. An MCI is an interpreter written in the language it interprets, allowing implementation of a subset or superset of the host language. The author details the MCI's implementation, covering parsing Python source code, building an Abstract Syntax Tree (AST), traversing the AST and executing statements, and crucial concepts like scoping, symbol tables, and handling control flow statements (e.g., while loops and if statements). This example provides a deep understanding of interpreter mechanics and showcases how to leverage Python's AST module and built-in functions to build more complex interpreters.

Jupyter Notebooks: E2E Testing and Documentation in One

2024-12-18

While developing a quantum computing library, the author leveraged Jupyter Notebooks as both user guides and end-to-end tests. By reading environment variables (like SERVER_URL) within the notebooks, they achieved parameterization, allowing execution by users and automated CI/CD pipelines. Two methods for running notebooks were explored: nbclient for simplicity, and nbconvert/jq for more control but increased complexity. The author opted for nbclient's ease of use, effectively integrating documentation maintenance and code testing, ensuring the integrity of both with every merge request.

Taming the Chaos: Centralizing and Structuring Error Handling in Go

2024-12-18

This article details the author's journey in tackling escalating error handling issues in a growing Go project. Initially, the simple approach to error handling devolved into chaos with confusing logs and untraceable errors. To solve this, a new error handling framework was designed and implemented. This framework employs a centralized, structured system using namespace codes to make errors meaningful and traceable. The core is a centralized declaration of error codes; each service layer returns only its own namespace codes, enriched with context information. The article thoroughly explains the design decisions, implementation, lessons learned, and migration strategy, offering valuable practical experience.

OpenAuth: A Universal, Self-Hosted OAuth 2.0 Server

2024-12-17

OpenAuth is a universal, standards-based, open-source authentication provider. Deployable as a standalone service or embedded within existing applications, it's framework-agnostic and runs on Node.js, Bun, AWS Lambda, or Cloudflare Workers.

Making Unsafe Rust Safer: Verification Tools for Unsafe Code

2024-12-17

Rust's popularity stems from its ability to eliminate memory and concurrency errors at compile time, but its `unsafe` code blocks can bypass these checks. This article explores tools for verifying unsafe Rust code, including code called from C or C++ libraries. It introduces runtime error detection tools—sanitizers—and Miri, an interpreter that deterministically finds undefined behavior. Sanitizers detect out-of-bounds memory access, data races, and more, while Miri provides more precise error reporting with code snippets. However, Miri currently doesn't support code called via FFI from C/C++, necessitating the use of C/C++ compiler sanitizers in such cases. These tools enhance the safety and reliability of Rust code, even when dealing with `unsafe` code or interacting with C/C++ libraries.

BYOJS: Embrace Native JavaScript for Web Development

2024-12-17

The BYOJS project champions building web applications with core JavaScript, rather than relying on heavy frameworks. While frameworks and languages like TypeScript are popular, BYOJS argues that building efficient web apps using the core JS language is a lost art. It encourages using loosely-coupled libraries instead of tightly-coupled frameworks, advocating for choosing the least powerful tool that gets the job done and prioritizing concise code. The project provides helpful utilities such as a simple key-value storage API, an asynchronous event emitter, a modal wrapper, and more. All code is MIT licensed.

Network Security Breakthrough: Trapping Intruders in a 'Network from Hell'

2024-12-17

Researchers at the University of Oulu's SensorFu team have developed a novel network security defense system inspired by the LaBrea tarpit technique. The system intercepts ARP requests and delays SYN-ACK responses, creating a multitude of virtual devices on the network to confuse intruders. This forces attackers to waste significant time identifying real devices, providing administrators with crucial time to patch vulnerabilities. Tests showed the system extends scan times to hours, drastically reducing attack success rates. Lightweight, efficient, and easy to deploy, this system offers robust network protection for organizations of all sizes.

OCR Challenge: Digitizing Saint-Simon's Memoirs

2024-12-17

The author spent several weeks using OCR to digitize a late 19th-century edition of the 18th-century French memoirs, *Les Mémoires de Saint-Simon*. This 45-volume behemoth, containing over 3 million words, is available online as images, but is difficult to read. The goal was to create a readable, searchable, and copyable text version. Challenges included poor image quality and parsing different page zones (headers, main text, margin comments, footnotes, etc.). Google Vision API was used for OCR, with a Python program processing the results to identify and separate text from different areas. While LLMs failed to reliably handle footnote references, the author improved the program and incorporated manual review, resulting in the release of the first volume.

Open Source Firmware: Necessity and Strategic Choices

2024-12-17

This article explores the necessity of open-source firmware. The author argues that firmware, as software controlling hardware, should adhere to free software principles. This is not only about freedom itself but also directly related to users' practical interests. Non-free firmware can restrict hardware functionality, hide security vulnerabilities, and even prevent users from fixing security issues. The article analyzes two viewpoints: one considers open-source firmware desirable but not necessary; the other advocates that all system software should be open-source. The author leans towards the former, believing that prioritizing the freedom of the operating system kernel is more important, but simultaneously emphasizes the benefits of open-source firmware and discusses how to promote it through strategic means.

Linear Algebra Powers Interactive Diagramming Editor

2024-12-17

Ivan Shubin, in developing his interactive diagramming editor Schemio, cleverly used matrix operations from linear algebra to solve a series of challenging problems. Initially, Schemio only supported simple shape creation and manipulation. However, when a hierarchical structure was introduced, coordinate transformations became complex. The author initially used a recursive approach but encountered issues with scaling and pivot points. Ultimately, Shubin leveraged matrices to represent transformations (translation, rotation, scaling), using matrix multiplication for coordinate conversion and ingeniously employing matrix inversion to solve the world-to-local coordinate conversion problem. Furthermore, matrix operations addressed the precise adjustment of an object's position and rotation when moving within the hierarchy, preventing unexpected jumps. Schemio's source code is open-source and available on GitHub.
