goke. High-performance, zero-allocation ECS for Go. Cache-friendly data orchestrator with type-safe iterators.

spring-boot-starter-web-http-versioninig-plugin. API versioning plugin for Spring-Boot-Starter-Web using HTTP headers

astar. A highly performant, fully generic A* solver for Go. Perfect for optimal pathfinding and abstract state-space search.

gokg. GOKG is a Go toolkit focused on practical 2D computational geometry. It centres on two core primitives — Vec for points and directions, and axis-aligned bounding boxes (AABB) — together with utilities that transform, combine, and analyse them. The library also models both finite and infinite planes.

jackson-mappers-wrapper. PoC which shows that Java 8 beans are serialized as easily as Scala case classes.

bam. Java 8 library to modeling and presenting the dynamics of a rigid body.

grpc-demo. Java gRPC server sample

javafx-demo. Practice with JavaFx

gokq. The library provides a Quadtree data structure for efficient spatial indexing and 2D range queries. Queries grazing a cyclic edge automatically wrap and fragment their search regions, so neighbour lookups stay accurate even when the area straddles the boundary.
