Hey HN, this is Will and David from Fortress (https://news.ycombinator.com/item?id=41426998). We use a lot of async Rust internally, and created this library out of a need for an async-aware concurrent hashmap since there weren’t many available in the Rust ecosystem. Whirlwind is a sharded HashMap with a fully asynchronous API. Just as dashmap is a replacement for std::sync::RwLock, whirlwind aims to be a replacement for tokio::sync::RwLock. It has a similar design and performance characteristics to dashmap, but seems to perform better in read-heavy workloads with tokio's…

Tasks are a primitive for asynchronous programming and an alternative to working with threads directly. Instead of creating a thread, performing work, then waiting on it using synchronization primitives, you only define a unit of work and let a scheduler decide when and where to execute it. The threads that the scheduler uses are created once and reused for many tasks throughout the program's lifetime. In most cases, creating and executing a task requires not even a single syscall and is a significantly faster operation than creating a thread, resulting in lower latency. Furthermore, tasks…

This project explores the integration of multithreading into the asyncio event loop in Python. While this was initially built with enhancing CPU utilization for FastAPI servers in mind, the approach can be used with more general async programs too. If you’re interested in diving deeper into the details, I’ve written a blog post about it here: https://www.neilbotelho.com/blog/multithreaded-async.html

Scapefree tier, from $9.99/mo▲59Hey HN, we've been using Claude Code daily for months, and built Scape to fix our biggest pain point: managing multiple worktrees quickly & reducing the mental load of switching between them quickly. What we built: Scape is a macOS menu bar app that sits on top of Claude Code and gives you: - One-click worktrees: click a button, get a new git worktree with a Claude session already working on it. Develop in parallel without leaving your current branch. - Toolkit: per-session actions like "Create PR", "Commit & Push", "Run & Fix Tests." Add your own with bash scripts or prompts. -…

A bit about me: Originally, I'm an iOS developer, but over time, I became interested in CLI and DevEx, which ultimately led to the creation of my first CLI utility in Swift. Project creation story: I enjoy interactive and functional command-line interfaces with good UX, which often includes beautifully displaying the progress of ongoing operations. I wanted the ability to show a nice progress status for any command or script, but at the time, I couldn't find any solutions that suited my needs. Most community offerings are good libraries for specific programming languages. So, I decided this…
