In plain words
Go-bt is a minimalist behavior tree library for the Go programming language. It provides a lightweight implementation for developers building systems that require behavior tree logic, commonly used in game development, AI, and automation. The library is designed for simplicity and ease of integration into Go projects.

Minimalist BT implementation in Go. Contribute to rvitorper/go-bt development by creating an account on GitHub.
Designed for background workers, game AI, mundane task automation, and asynchronous logic. Instead of time.Sleep or infinite while loops, go-bt uses a cooperative multitasking model. Nodes return state instantly, yielding control back to the supervisor. Your blackboard is the custom state your tree will read and manipulate. Because the library uses Go Generics, it can be any struct. type WorkerState struct { IsConnected bool PendingTasks int } 2. Build the Tree You can use the go-bt nodes to assemble your logic. This example asserts that the worker is connected before attempting to process tasks: package main import ( "time" "context" "go-bt/core" "go-bt/composite" "go-bt/leaf" ) func…from github.com

Gonzo – A Go-based TUI for log analysis (OpenTelemetry/OTLP support)2025 · github.com · ▲74We built Gonzo to make log analysis faster and friendlier in the terminal. Think of it like k9s for logs — a TUI that can ingest JSON, text, or OpenTelemetry (OTLP) logs, highlight and boil up patterns, and even run AI models locally or via API to summarize logs. We’re still iterating, so ideas and contributions are welcome!

We are building `pcz` to provide a reimagination of Go the language, in an effort to make it suitable for all kinds of programming tasks, and currently you can use it to build efficient web applications in Go using the generated Web SDK (as shown with the live web demo[1]). The journey is just starting, any suggestions? or any critics? [1]: https://primecitizens.github.io/livedemos/10-plat-web/

I think there's many classes of application (particularly legacy architecture) that can benefit from these kinds of analysis tooling. My next post will be about composing all these together, an exciting project I call…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
