Sangria
Scala GraphQL implementation
Sangria is a Scala GraphQL implementation. It is an example of GraphQL server written with Play framework and Sangria. It also serves as a playground, where you can interactively execute GraphQL queries and play with some examples. If you want to use sangria with a react-relay framework, then you also may be interested in sangria-relay. Sangria is a spec-compliant GraphQL implementation, so it works out of the box with Apollo, Relay, GraphiQL and other GraphQL tools and libraries. Since GraphQL has a type system, the server defines a schema that the client can query using the introspection API. This provides the client with a set of possibilities. After the client got this information and decided which parts of the data it needs, it is able to describe its data requirements in form of a GraphQL query. An important aspect of GraphQL is that it’s completely backend agnostic. -

edgetunnel
edgetunnel 2.0 VLESS/Trojan
edgetunnel is a modified version of a serverless tunnelling solution designed to run on platforms like Cloudflare Workers and Pages, enabling protocols such as VLESS and Trojan to be exposed through edge-functions rather than traditional servers. The project’s fork by cmliu emphasizes conversion of protocol configuration (especially VLESS) into subscription links, so that users can deploy and then generate “Clash” or “Sing-box” compatible subscription content easily. It provides a streamlined way to host proxy endpoints without managing a full server stack, instead leveraging the edge network of Cloudflare for distribution and potential performance. Because it runs at the edge, latency can be minimized and deployment complexity simplified; users supply configuration variables (host, port, UUID, path) and the script handles mapping to technical protocols and subscription formatting. -

AlphaZero.jl
A generic, simple and fast implementation of Deepmind's AlphaZero
Beyond its much publicized success in attaining superhuman level at games such as Chess and Go, DeepMind's AlphaZero algorithm illustrates a more general methodology of combining learning and search to explore large combinatorial spaces effectively. We believe that this methodology can have exciting applications in many different research areas. Because AlphaZero is resource-hungry, successful open-source implementations (such as Leela Zero) are written in low-level languages (such as C++) and optimized for highly distributed computing environments. This makes them hardly accessible for students, researchers and hackers. Many simple Python implementations can be found on Github, but none of them is able to beat a reasonable baseline on games such as Othello or Connect Four. As an illustration, the benchmark in the README of the most popular of them only features a random baseline, along with a greedy baseline that does not appear to be significantly stronger. -
