NATS messaging enables the exchange of data that is segmented into messages among computer applications and services. These messages are addressed by subjects and do not depend on network location. This provides an abstraction layer between the application or service and the underlying physical network. Data is encoded and framed as a message and sent by a publisher. The message is received, decoded, and processed by one or more subscribers.

Unboxed multidimensional bit packed Bool arrays with fast aggregate operations based on lifting Bool operations to bitwise operations.

QGIS is a Geographic Information System (GIS) which manages, analyzes and display databases of geographic information.

Halide is a programming language designed to make it easier to write high-performance image and array processing code on modern machines. Halide currently targets: * CPU architectures: X86, ARM, MIPS, Hexagon, PowerPC, RISC-V * Operating systems: Linux, Windows, macOS, Android, iOS, Qualcomm QuRT * GPU Compute APIs: CUDA, OpenCL, OpenGL Compute Shaders, Apple Metal, Microsoft Direct X 12 Rather than being a standalone programming language, Halide is embedded in C++. This means you write C++ code that builds an in-memory representation of a Halide pipeline using Halide's C++ API. You can then compile this representation to an object file, or JIT-compile it and run it in the same process.

At its core, Pacemaker is a distributed finite state machine capable of co-ordinating the startup and recovery of inter-related services across a set of machines.
