    lockfree

    A collection of lock-free data structures written in standard C++11

    lockfree is a collection of lock-free data structures written in standard C++11 and suitable for all platforms - from deeply embedded to HPC. Lock-free data structures are data structures that are thread and interrupt-safe for concurrent use without having to use mutual exclusion mechanisms. They are most useful for inter-process communication and often scale much better than lock-based structures with the number of operations and threads.

    Elixir Code Smells

    Elixir Code Smells

    Catalog of Elixir-specific code smells

    Elixir-Code-Smells is a research-driven catalog of code smells specific to the Elixir programming language. Unlike generic code smell lists, this project identifies issues emerging from Elixir’s functional, concurrent, and process-based nature. Initially compiled via grey literature (blogs, talks, forums), the catalog now includes 23 Elixir-specific smells plus 12 traditional smells adapted to Elixir. Each entry documents the name, category, problem, example, refactoring strategy, and step-by-step treatments. The smells are grouped into two categories: design-related (coarse-grained, harder to detect, affecting architecture/processes) and low-level concerns (fine-grained, often readability and maintainability issues). ...

    Gas Town

    Gas Town - multi-agent workspace manager

    ...It tackles the common challenge where individual AI agents lose context on restart by persisting work state using git-backed hooks, enabling reliable and resumable multi-agent workflows that scale comfortably beyond just a handful of concurrent agents. The system introduces concepts like The Mayor (the primary coordinator agent), Rigs (project containers), Crew Members (developer workspaces), and Polecats (ephemeral worker agents), organizing work into structured convoys and beads that can be tracked through command-line interfaces. By integrating with tools like tmux and supporting git worktrees, Gastown enables interactive sessions where agents and humans collaborate fluidly, with tracked progress, handoffs, and historical records.
