Go

Python's PyYAML long defaulted to YAML 1.1, Go's go-yaml v2 is also 1.1, and only v3 switched to 1.2 semantics.

Go's Channel is a pipe for communication between goroutines; it is essentially a block of shared memory on the heap and is thread-safe.

Go has no classes, only structs and interfaces. A struct field whose first letter is uppercase means public, and lowercase means private to the package.

In Go Context, canceling a child node does not affect the parent node or sibling nodes; when the parent node is canceled, all descendant nodes receive the cancellation signal in a cascade.

In Go, Context is usually passed as the first parameter of a function, and the convention is not to store it in a struct field, because its lifecycle should strictly follow a single request.

ghealth requires Go 1.23 or higher and Git to build from source.

There have long been two approaches to memory safety in systems programming languages: compile-time static checking, represented by Rust, and runtime GC, represented by Go and Java.

After Legion's gateway architecture adjustment, preserving real code in context led the Agent to switch into exact-imitation mode during Go development, able to replicate the architectural layout (handler -> service -> repository) and embed a new microservice into an existing monolith without breaking dependencies.

MLX-C 是 MLX 的 C 语言绑定层，Ollama 主体使用 Go 编写，通过 cgo 机制调用 MLX-C 进行底层高性能张量计算。

Common error-swallowing language patterns include: the empty `catch(e){}` block in JavaScript, `if err != nil { return nil }` in Go (ignoring err), and the mindless `.unwrap_or_default()` in Rust.
