the open-source database for the realtime web.
RethinkDB pushes JSON to your apps in realtime.
RethinkDB is the first open-source scalable database built for realtime applications. It exposes a new database access model, in which the developer can tell the database to continuously push updated query results to applications without polling for changes. RethinkDB allows developers to build scalable realtime apps in a fraction of the time with less effort.
Real-time HTTP Intrusion Detection.
teler is an real-time intrusion detection and threat alert based on web log that runs in a terminal with resources that we collect and provide by the community. ❤️
Fast Open-Source OLAP DBMS.
ClickHouse® is an open-source column-oriented database management system that allows generating analytical data reports in real-time.
Market leading RTOS (Real Time Operating System) for embedded systems with Internet of Things extensions. Real-time operating system for microcontrollers?
Developed in partnership with the world’s leading chip companies over an 18-year period, and now downloaded every 170 seconds, FreeRTOS is a market-leading real-time operating system (RTOS) for microcontrollers and small microprocessors. Distributed freely under the MIT open source license, FreeRTOS includes a kernel and a growing set of IoT libraries suitable for use across all industry sectors. FreeRTOS is built with an emphasis on reliability and ease of use.
The Zephyr® Project is an open source scalable real-time operating system (RTOS) supporting multiple hardware architectures including ARC, ARM, RISC-V and X86. The Zephyr OS is a proven RTOS used in products today.
Zephyr OS is modular and supports multiple architectures, developers can easily tailor an optimal solution to meet their needs. Zephyr OS is used in a broad spectrum of applications from simple connected sensors to complex edge systems.
Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8878.
Mercure is an open protocol for real-time communications designed to be fast, reliable and battery-efficient. It is a modern and convenient replacement for both the Websocket API and the higher-level libraries and services relying on it.
