Literate Programming: Making Code More Readable

Literate programming, a paradigm invented by Donald Knuth, prioritizes code readability for humans over immediate machine execution. This allows programmers to develop programs in a more natural, thought-driven order. Literate programs interweave natural language explanations with code snippets, enhancing understanding and collaboration. The Literate tool, described here, aims to simplify and extend Knuth and Levy's original CWEB system. It supports multiple languages, syntax highlighting, pretty-printing to HTML, Markdown-based authoring, and offers a command-line interface for compiling code and generating HTML documentation. The project is open-source and welcomes contributions.

Homegrown Lexical Closures in a Lisp-like uxn Environment

2025-06-19

The author describes niënor, a Lisp-like environment for the uxn virtual machine, focusing on its innovative approach to implementing lexically scoped closures. Instead of the complex approach of copying functions and replacing unbound variables at runtime, niënor cleverly adds environment variables as parameters to lambda functions at compile time. At runtime, a wrapper function (portal) is generated to pass these environment variables. This avoids runtime code generation and complex address calculations, providing an efficient and elegant solution for closures. The system also includes `malloc` and `free` for dynamic memory management of these closures.

Public/Protected/Private: A Redundant OOP Feature?

2025-06-19

This article challenges the necessity of access modifiers (public, protected, private) in object-oriented programming. The author argues that interfaces and inheritance combined can achieve the same functionality without the need for an extra mechanism. The existence of access modifiers might stem from an oversight in the design of Simula, leading to redundant functionality. For cleaner code, the author suggests avoiding access modifiers and advocates for composition over inheritance.

Marginalia Search Engine Upgrades: Online Status and Ownership Change Detection

2025-06-19

The Marginalia Search Engine team implemented a new system, 'ping-process,' to detect server online status and significant website changes, including ownership transfers and parking. Primarily using HTTP HEAD requests and DNS queries, the system analyzes certificate details, security posture, and server headers to identify changes. Data is stored in 'snapshot' and 'event' tables, the former holding current information and the latter historical events. The system overcame scheduling and certificate validation challenges, showing early success in identifying parked domains. Future plans include refining the ownership change detection model and integrating it into crawler strategies for improved efficiency.

OpenAPI: Revolutionizing API Development

In software development, efficient application building, maintenance, and integration are paramount. The OpenAPI Specification (OAS), a universal language for describing RESTful APIs, is key to achieving this efficiency. It provides a detailed blueprint for your API, encompassing endpoints, request and response formats, and authentication methods. Benefits of OAS include: improved team collaboration, automation (e.g., auto-generating client SDKs and server stubs, interactive documentation, and automated testing), enhanced developer experience, fostering a thriving partner ecosystem, and driving an API-first development culture. Creating an OAS can be done manually, via code-first generation, or with AI assistance, each with its own pros and cons. OpenAPI and Swagger are distinct: OpenAPI is the specification itself, while Swagger is a toolset built around the OpenAPI Specification. Adopting OpenAPI is a strategic imperative for any organization building robust, scalable applications.

Bridging Elixir and Go Backends with a Crystal Wrapper

Bridging Elixir and Go Backends with a Crystal Wrapper

The Mozi team needed to connect a new Elixir Phoenix LiveView app to an existing Go backend. They explored NIFs and Ports, but ultimately chose Erlang's C Node approach, using Crystal to write a C wrapper for improved maintainability. This decouples the codebases at compile and runtime, leveraging `Node.list` in Elixir to detect C node connectivity and S6 for in-container restarts. While there's a performance penalty crossing the C/Go boundary, it's acceptable for their use case. The result is a slick three-language (Elixir, Crystal, Go) mashup that enhances maintainability.

BeeKEM: A Novel Key Encapsulation Mechanism for Decentralized Secure Group Messaging

This article delves into BeeKEM, a novel key encapsulation mechanism for decentralized secure group messaging. Unlike traditional TreeKEM, BeeKEM enhances recovery from conflicting offline updates and network splits by allowing multiple group state "epochs" to coexist simultaneously. When members receive conflicting updates, they retain all received keys, marking them as "conflicted," thus continuing to decrypt and read messages from conflicting epochs. Updates proceed by treating conflicted nodes as blank. BeeKEM unlocks new possibilities for building local-first apps with stronger privacy and autonomy.
