这是一个关于分布式系统架构和后端基础设施设计的综合教育资源和学习指南。它为掌握设计复杂软件系统所需的扩展性、可靠性和性能原则提供了结构化课程。 该仓库通过提供一种系统化的技术面试准备方法脱颖而出，结合了设计模式、架构权衡和间隔重复工具，帮助用户记忆复杂概念。它强调约束驱动的分析，教授用户在起草架构设计时如何评估延迟、一致性和可用性等相互竞争的需求。 内容涵盖了广泛的系统设计能力，包括数据库扩展、流量管理和基础设施优化策略。它详细介绍了水平扩展、多层缓存、异步通信和服务发现技术，同时还提供了用于执行资源估算和容量规划的框架。 文档以学习指南的形式组织，为后端工程和大规模系统设计的基础知识提供了系统化的路径。

Joplin is an open-source, cross-platform note-taking application designed for secure, private knowledge management. It functions as a local-first productivity platform, maintaining a complete relational database on the user's device to ensure offline availability and high-performance data retrieval. The application prioritizes data sovereignty by implementing an end-to-end encryption layer, which secures all information locally with a master key before any synchronization occurs. The platform distinguishes itself through a delta-based synchronization engine that transmits only specific file c

Solidtime is time tracking software designed for freelancers and agencies to record work durations, manage billable hours, and monitor labor allocation. It serves as a professional services automation tool that organizes work into clients and projects while managing team member assignments. The system features a billable rate manager that defines hourly costs at the organizational, member, and project levels using hierarchical overrides to calculate total billing. It includes a project management tool for organizing clients and tasks into hierarchies with role-based access permissions. The p

Viewers is a zero-footprint DICOMweb medical imaging viewer and a modular plugin framework. It serves as a diagnostic interface for rendering 2D and 3D medical images, providing a web-based clinical workflow engine to automate image layouts and toolsets. The project distinguishes itself through a highly extensible architecture that allows for the development of custom clinical workflows, specialized viewing modes, and the integration of external functional extensions. It includes a dedicated command line interface for managing these plugins and supports white-labeling through a comprehensive
