...GoNB leverages that compilation speed to implement a full-featured (at least it's getting there) Jupyter notebook kernel. As a side benefit it works with packages that use CGO — although it won't parse C code in the cells, so it can't be used as a C kernel. It already includes many goodies: cache between cell of results, contextual help and auto-complete (with gopls), compilation error context (by mousing over), bash command execution, images, html, etc. See the tutorial. It's been heavily used by the author (in developing GoMLX, a machine learning framework for Go), but should still be seen as experimental — if we hear success stories from others, we can change this.

...It also passes all values as pointers which causes large numbers of dynamic memory allocations, more frequent garbage collections, and higher memory usage. confluent-kafka-go is a cgo based wrapper around librdkafka, which means it introduces a dependency to a C library on all Go code that uses the package. It has much better documentation than sarama but still lacks support for Go contexts. goka is a more recent Kafka client for Go which focuses on a specific usage pattern. It provides abstractions for using Kafka as a message passing bus between services rather than an ordered log of events.

...The material covers measurement workflows, data and algorithm changes, benchmarking, program tuning, garbage collection, compiler behavior, and standard-library pitfalls. Later chapters examine unsafe operations, cgo, assembly, advanced techniques, service-wide optimization, profiling, and tracing. The project emphasizes measuring real bottlenecks before changing code rather than relying on intuition. Community contributors can expand topics, add resources, and develop additional prose or examples. The book is available in English, Chinese, Spanish, and Brazilian Portuguese.

...It exposes Go-friendly abstractions for windows, buttons, boxes, tables, menus, drawing areas, text fields, and other controls. Applications use native Windows controls, macOS interfaces, or GTK widgets depending on the operating system. The package relies on cgo and supports Windows, macOS, and Unix-like systems with GTK 3. Example programs demonstrate the available controls and application structure. A Windows manifest helper simplifies enabling modern Common Controls support in compiled binaries. Like libui itself, the project is mid-alpha and should be treated as experimental rather than a fully mature GUI toolkit.
