Payload is a headless content management system and application framework that uses a code-first approach to define data schemas and administrative interfaces. By utilizing a centralized, type-safe configuration object, it automatically generates database schemas, API endpoints, and a fully customizable admin panel. The system is built on a database-agnostic architecture, allowing it to interface with various storage engines while providing a unified, type-safe API for server-side operations, REST, and GraphQL. What distinguishes Payload is its deep extensibility and developer-centric design.

This project is a comprehensive technical interview question bank and reference library designed for software engineering roles at major technology companies. It serves as a study guide and knowledge base covering the core principles of high-performance systems programming and computer science theory. The collection focuses on deep technical domains, including C++ language mastery, distributed systems design, and database engineering. It provides detailed material on consensus protocols, cluster coordination, and the architectural differences between SQL and NoSQL implementations. The resour

usql is a universal SQL command-line interface used to connect to and manage multiple SQL and NoSQL databases through a single unified tool. It provides a standardized interface for executing queries across various data stores and serves as a multi-database query tool and schema inspector. The tool distinguishes itself by enabling cross-database data migration, allowing users to pipe result sets from one active database connection directly into another. It also features terminal-based data visualization, which renders query results as graphical charts, graphs, and images directly within the t

Enso is a visual dataflow programming environment and multi-language data processing engine that compiles Enso, Python, Java, and JavaScript into a unified representation with a shared memory model for zero-overhead inter-language calls. It functions as a self-service data preparation and analysis platform where users can build data pipelines by connecting nodes in a graph, switching between a no-code visual interface and a code view while keeping all changes reviewable. The platform also serves as a cloud data workflow scheduler and API exposer, allowing workflows to run on a timetable or be

Realm is a mobile database: an alternative to SQLite & key-value stores

ShareJS ist eine kollaborative Dokumentendatenbank und Synchronisations-Engine, die für die Verwaltung gemeinsam genutzter Zustände in Echtzeit konzipiert ist. Sie bietet eine Operational-Transform-Sync-Engine, um die gleichzeitige Bearbeitung von Klartext- und JSON-Daten zu ermöglichen, sowie eine RESTful-Synchronisations-API für die Verwaltung von Dokumentzuständen via HTTP. Das System verfügt über eine Offline-First-Datensynchronisationsschicht, die lokale Änderungen bei Verbindungsunterbrechung in eine Warteschlange stellt und Bearbeitungen bei Wiederherstellung der Verbindung automatisch überträgt. Es enthält zudem eine Middleware-Zugriffskontrollschicht, die Datenbankanfragen abfängt, um Sicherheitsrichtlinien durchzusetzen und Anfragen umzuschreiben. Die Plattform deckt ein breites Spektrum an Funktionen ab, einschließlich Live-Query-Abonnements, Echtzeit-Änderungsbenachrichtigungen und gleichzeitiger Inhaltssynchronisation. Diese Komponenten ermöglichen die Erstellung von Daten-Feeds, bei denen Clients sofort benachrichtigt werden, wenn Backend-Dokumente, die bestimmten Abfragen entsprechen, aktualisiert werden.

MyBatis-Flex is an object-relational mapping framework for Java that extends MyBatis with a fluent API and automated CRUD operations. It provides a data access suite featuring an automatic CRUD data mapper, a type-safe SQL query builder, and a row-based query engine for manipulating records without predefined entity classes. The framework includes a multi-dialect SQL translator that converts generated syntax across different database engines, such as MySQL, PostgreSQL, and Oracle. It further distinguishes itself by offering annotation-free entity mapping using runtime reflection and naming co

Home-gallery is a self-hosted media management server designed to organize, view, and search personal photo and video collections. It functions as a local application that indexes media files from your storage, generates web-friendly previews, and provides a browser-based dashboard for browsing your archives. The system is built to maintain full control over your digital assets while enabling intelligent discovery and cross-device streaming. What distinguishes this platform is its focus on metadata portability and visual intelligence. It utilizes sidecar files to store media information, ensu
