Swift NIO is a low-level, event-driven network framework for the Swift language. It serves as an asynchronous network protocol stack and I/O library designed to build high-performance network servers and clients that handle thousands of simultaneous connections. The framework functions as a high-concurrency network engine that dispatches events across multiple CPU cores. It enables the implementation of custom network protocols by processing raw bytes through a sequence of reusable data transformation handlers. The system provides capabilities for non-blocking I/O multiplexing, asynchronous

ArduinoJson is a C++ library for parsing and manipulating JSON data and MessagePack binary streams on microcontrollers with limited memory and processing power. It provides the core primitives necessary for embedded data serialization and parsing, enabling devices to exchange structured data over serial or network interfaces. The library is distinguished by its focus on microcontroller memory management, employing strategies such as pool-based allocation, string deduplication, and non-owning string views to minimize RAM usage. It further optimizes for constrained environments by allowing cons

DiskLruCache is a disk-backed key-value cache library for Android and Java environments that stores data on the filesystem within a configurable byte limit. It uses a least-recently-used (LRU) eviction policy to automatically remove old entries when the cache exceeds its allocated size, and maintains a journal file to reconstruct its in-memory state after a process restart. The cache provides atomic write operations that first write new data to a temporary file before atomically renaming it, preventing partial or corrupted reads during concurrent access. It returns frozen snapshots of cache e

This is an open-source, crowd-sourced wiki textbook that teaches Linux system programming in C. It covers the core operating system concepts of process management through the fork-exec-wait model, dynamic memory allocation using implicit free list heap allocators, inode-based file systems, inter-process communication via pipes and shared memory, POSIX threads with synchronization primitives, signal-based asynchronous notification, virtual memory with page table translation, and runtime diagnostics using Valgrind and GDB. The textbook distinguishes itself by providing practical, implementation

Janet es un lenguaje de programación dinámico basado en Lisp que cuenta con una máquina virtual de bytecode basada en registros y un motor de scripting integrable. Funciona como un runtime de concurrencia basado en fibras e incluye un motor de análisis basado en Gramáticas de Expresión de Análisis (PEG). El proyecto se distingue por su capacidad de integrarse en aplicaciones de C o C++ a través de una interfaz de cabecera mínima. Utiliza un sistema de macros al estilo Lisp para la transformación de código en tiempo de compilación y emplea herencia de tablas basada en prototipos para el comportamiento orientado a objetos. El runtime cubre un amplio conjunto de capacidades, incluyendo la gestión de IO asíncrona a través de un bucle de eventos no bloqueante, interoperabilidad de bibliotecas nativas a través de una interfaz de funciones externas y procesamiento de texto integral utilizando gramáticas PEG. También proporciona herramientas para la automatización del sistema, como un bucle de lectura-evaluación-impresión (REPL), un sistema de módulos para la resolución de símbolos y utilidades para la comunicación de sockets de red y la gestión del sistema de archivos. El entorno incluye herramientas de diagnóstico para la depuración de la ejecución de bytecode y puede empaquetar el código fuente en ejecutables binarios independientes.

pyserial is a cross-platform Python library for reading and writing binary data to serial ports and hardware devices. It provides a serial port enumeration tool for identifying available hardware and retrieving device path metadata. The project includes a network implementation for controlling remote serial port functions and signal lines over TCP/IP via the RFC 2217 standard. It also features a serial-to-TCP bridge for forwarding raw data between local ports and network sockets, as well as a specialized interface for managing half-duplex RS485 communication and RTS toggling. The library cov
