Zigtools, a community-driven initiative supporting the Zig programming language, recently raised concerns about Zigbook, a new resource claiming to offer a project-based approach without AI involvement. Upon investigation, Zigtools discovered that Zigbook's content, including its playground features, closely mirrored their own. Both the Zigtools Playground and Zigbook used identical WebAssembly (WASM) blobs, with specific files, like `zig.wasm` and `zls.wasm`, showing byte-for-byte duplication. This overlap hints at a clear case of plagiarism, especially given Zigbook's claims of originality. Zigtools also found similarities in the JavaScript code powering both playgrounds. While Zigbook altered some parts to obscure direct copying, key sections remained unchanged. Notably, Zigbook failed to incorporate essential JavaScript code necessary for proper integration with the ZLS WASM binary, raising questions about their understanding of the technology or their intentions. Zigtools pointed out that while the MIT license permits code sharing, Zigbook did not adhere to its requirements and even closed a pull request from Zigtools aimed at correcting these violations. In light of these issues, Zigtools emphasized the need for the Zig community to avoid Zigbook and instead recommended reliable learning resources like the official Zig learn page and Ziglings. They also announced a fundraising effort to support their work on ZLS, calling for community contributions to sustain their development efforts. The situation illustrates the ongoing challenges of maintaining integrity within open-source projects while fostering a collaborative learning environment.
