This project is a privacy-focused, self-hosted metasearch engine that aggregates results from a wide array of web, academic, and media sources into a single, unified interface. By acting as a proxy between the user and external search providers, it strips identifying headers and tracking parameters from requests, ensuring that search activity remains anonymous and protected from third-party profiling. The platform distinguishes itself through a modular, plugin-based architecture that allows for extensive customization of search behavior, result filtering, and interface branding. It supports a

This framework is a cross-platform software development kit designed for building native mobile and desktop applications from a single shared codebase. It provides a unified programming interface that allows developers to construct user interfaces using declarative markup, which are then rendered as native components on each target operating system. The framework distinguishes itself through a multi-targeting build system that consolidates platform-specific resources and native control mapping into a unified project structure. It includes a data-driven binding engine that synchronizes applica

ip2region is an offline IP geolocation library and framework designed to resolve IPv4 and IPv6 addresses to city-level regional information using local binary data files. It functions as a binary IP database compiler and a cross-language search client, allowing for regional lookups without relying on external APIs. The project distinguishes itself through a specialized binary format that supports high-performance query optimization. It employs adjacent-segment IP merging and deduplicated region storage to minimize the database footprint, while utilizing memory-mapped file caching and vector-i

This project is a cross-platform messaging SDK and client development library used to build custom Telegram applications. It functions as a comprehensive framework that manages network encryption, local data storage, and API communication, providing a C-compatible JSON interface that allows integration with any programming language. The library distinguishes itself by providing a full database manager for encrypted local caching and synchronized state, alongside a dedicated bot framework for creating interactive bots with business account integration. It enables the implementation of speciali

MapDB ist eine eingebettete Datenbank-Engine und eine Bibliothek für disk-basierte Collections, die Java-Collections auf der Festplatte oder außerhalb des Heaps speichert. Sie fungiert als lokale Datenverarbeitungs-Engine, die darauf ausgelegt ist, Datensätze zu verarbeiten, die den verfügbaren physischen RAM überschreiten. Das Projekt nutzt Off-Heap-Datenspeicherung, um den Overhead der Garbage Collection zu eliminieren, und verwendet Disk-Overflow-Caching, um Speicher- und Festplattennutzung auszubalancieren. Es bietet spezialisierte Dienstprogramme zum Filtern und Analysieren großer Mengen lokaler Daten auf einer einzelnen Maschine. Das System stellt die Datenintegrität durch ACID-konforme Transaktionen und Multi-Version-Concurrency-Control sicher. Es unterstützt persistente Maps, Sets und Queues unter Verwendung von B-Tree-Indizierung und ein sequentielles Transaktionsprotokoll für die Dauerhaftigkeit. Das Systemverhalten und interne Engine-Operationen können über konfigurierbare Logging-Level und Ausgabeformate überwacht werden.

Open Location Code is a geocoding library and toolset used to transform global latitude and longitude coordinates into standardized, human-readable alphanumeric digital addresses and back again. It functions as an offline location coding system that generates unique identifiers for any location on Earth, specifically providing digital addresses for areas where formal street addresses or postal systems are missing. The system operates as a stateless algorithmic process, allowing coordinates to be encoded and decoded without the need for network access, internet connections, or external databas

This project is a containerized search infrastructure designed to deploy a privacy-focused metasearch engine. It acts as a self-hosted search proxy that aggregates results from multiple external web, image, and academic search providers while anonymizing requests and stripping trackers to protect user identity. The system utilizes Docker to orchestrate the search instance, integrating caching mechanisms and reverse proxy support to ensure a private and efficient search environment. It employs a modular adapter-based integration to standardize diverse external API responses and a processing pi
