Lihua design orchestration simulation system is mainly based on MFC and OpenGL, and uses linked lists to implement a hierarchical particle system. The first time we designed and implemented a complete software system, we gained a lot. Of course, now I look back at this system and find that this system architecture is so poorly designed.

1. Identify the fireworks discharge process.
2. Analyze the particle motion rule. Underst
Helm IntroductionDeploying container cloud Applications (container or microservices orchestration) in Kubernetes is a challenging task, Helm is to simplify the installation of a client tool for deploying container cloud applications in Kubernetes. Helm enables developers to define, install, and upgrade container cloud applications in Kubernetes. At the same time, the container cloud application can also be shared through helm.The overall architecture
