Show HN: Pyreqwest – Powerful and fast Rust-reqwest based HTTP client for Python Python has lacked a batteries-included HTTP library that would have both async and sync clients. Httpx (httpcore), which has offered this, is unfortunately pretty much unmaintained and suffering from huge perf issues ( https://ift.tt/cJynxiF ). I built pyreqwest HTTP client for Python that is fully Rust based on top of reqwest. It includes all features reqwest offers plus some more. Also including unit testing utilities (mocking, ASGI app support). Go check https://ift.tt/ravgPj9 :) https://ift.tt/ravgPj9 October 13, 2025 at 02:47AM

Show HN: I built a simple ambient sound app with no ads or subscriptions I’ve always liked having background noise while working or falling asleep, but I got frustrated that most “white noise” or ambient sound apps are either paywalled, stuffed with ads, or try to upsell subscriptions for basic features. So I made Ambi, a small iOS app with a clean interface and a set of freely available ambient sounds — rain, waves, wind, birds, that sort of thing. You can mix them, adjust volume levels, and just let it play all night or while you work. Everything works offline and there are no hidden catches. It’s something I built for myself first, but I figured others might find it useful too. Feedback, bugs, and suggestions are all welcome. https://ift.tt/QDnRmId... https://ambisounds.app/ October 12, 2025 at 09:49PM

Show HN: Modeling the Human Body in Rust So I Can Cmd+Click Through It I started this trying to understand two things: why my Asian friends turn red after drinking, and why several friends all seemed to have migraine clusters. I was reading medical papers and textbooks, but kept getting lost jumping between topics. I thought: what if I could just Cmd+Click through this like code? What if "ALDH2 gene" was actually clickable, and took me to the variant, the phenotype, the population frequencies? So I started modeling human biology in Rust with my Ralph agent (Claude in a loop, ty ghuntley). Turns out the type system is perfect for this. Every biological entity is strongly-typed with relationships enforced at compile time. After 1 day of agent coding: - 277 Rust files, ~95k lines of code - 1,561 tests passing - 13 complete organ systems - Genetics with ancestry-specific variants - Clinical pathology models Try it: git clone https://ift.tt/gl1OcKF cd open_human_ontology cargo run...

Show HN: GYST – A new take on the desktop interface (alpha) Hi HN! I’ve been working on a tool that merges file explorer, whiteboard, bookmarking, note-taking & simple graphic design into one lightweight interface. The idea is to make all these tools feel like one fluid space instead of 5 separate tools. The hope is to replicate the feeling of a physical desk : where order and freedom coexist. This 15-min video walks through the current alpha and the vision for the full product : https://youtu.be/AcWzuBBuiPM I’d love your feedback — especially around the concept and UX. The alpha is online if you want to try it: https://gyst.fr This is a solo project for now, inspired by the “second brain” / PKM movement and my own frustration with fragmented tools and outdated UX. https://www.youtube.com/watch?v=AcWzuBBuiPM October 9, 2025 at 11:39PM

Show HN: I built a local-first podcast app I worked on early podcast software in 2004 (iPodder/Juice) and have been a heavy podcast consumer ever since. I wanted a podcast app that respects your privacy and embraces the open web—and to explore what's possible in the browser. The result is wherever.audio, which you can try right now at the link above. How it works: It's a progressive web app that stores all your subscriptions and data locally in your browser using IndexedDB. Add it to your home screen and it feels native. Works offline with downloaded episodes. No central server storing your data—just some Cloudflare/AWS helpers to smooth out browser limitations. What makes it different: - True local-first: Your data stays on your device - Custom feeds: Add any RSS feed, not just what's in a directory - On-device search: Search across all feeds and episodes, including your custom ones - Podcasting 2.0 support: Chapters, transcripts, funding tags, and others - Auto-generated ...

Show HN: Arc – high-throughput time-series warehouse with DuckDB analytics Hi HN, I’m Ignacio, founder at Basekick Labs. Over the past months I’ve been building Arc, a time-series data platform designed to combine very fast ingestion with strong analytical queries. What Arc does? Ingest via a binary MessagePack API (fast path), Compatible with Line Protocol for existing tools (Like InfluxDB, I'm ex Influxer), Store data as Parquet with hourly partitions, Query via DuckDB engine using SQL Why I built it: Many systems force you to trade retention, throughput, or complexity. I wanted something where ingestion performance doesn’t kill your analytics. Performance & benchmarks that I have so far. Write throughput: ~1.88M records/sec (MessagePack, untuned) in my M3 Pro Max (14 cores, 16gb RAM) ClickBench on AWS c6a.4xlarge: 35.18 s cold, ~0.81 s hot (43/43 queries succeeded) In those runs, caching was disabled to match benchmark rules; enabling cache in production gives ~20% faster re...

Show HN: A Digital Twin of my coffee roaster that runs in the browser I built this website to host a data-driven model of my coffee sample roaster. I realized after 20 or so batches on the machine that while the controls are intuitive (heat, fan, and drum speeds), the physics can be unintuitive. I wanted to use my historical roast data to create and tune a model that I could use to do roast planning, control, and to help me build my own intuition for roasting. This website lets you interact with my roaster in a virtual, risk-free setting! The models are custom Machine Learning modules that honor roaster physics and bean physics (this is not GPT/transformer-based). Buncha math. The models are trained on about a dozen real roasts. The default bean model is an Ethiopian Guji bean. My next steps are to add other roasters and the ability to practice control/reference tracking. https://ift.tt/W8Q53LH October 6, 2025 at 11:31PM

Show HN: World Amazing Framework: Like Django for Civilization Any initial thoughts? This framework is meant to be a tool for construction, so if you want to play around with it for creating potential specific implementations, you can drop the contents of the website, the GitHub README, and the entire overview.md into an AI chat, and that should be enough to use the framework, at least conceptually. Would y'all want me to pre-prime a chat in Google AI Studio with the full context of the plan and some basic direction for discourse? I can share a link to a ready-to-go environment. The core documentation should answer most mechanical questions. And if you feed the docs into an AI chat, you can ask it any question you may have, or to simply ask it to explain something in different ways, or hypothesize solutions to any world issue, either systemic or regional. Gemini Pro 2.5 can take the full doc in one prompt, and its ability to co-create ideas is remarkable. I've been using it mos...

Show HN: Run – a CLI universal code runner I built while learning Rust Hi HN — I’m learning Rust and decided to build a universal CLI for running code in many languages. The tool, Run, aims to be a single, minimal dependency utility for: running one-off snippets (from CLI flags), running files, reading and executing piped stdin, and providing language-specific REPLs that you can switch between interactively. I designed it to support both interpreted languages (Python, JS, Ruby, etc.) and compiled languages (Rust, Go, C/C++). It detects languages from flags or file extensions, can compile temporary files for compiled languages, and exposes a unified REPL experience with commands like :help, :lang, and :quit. Install: cargo install run-kit (or use the platform downloads on GitHub). Source & releases: https://ift.tt/stPF3I5 I used Rust while following the official learning resources and used AI to speed up development, so I expect there are bugs and rough edges. I’d love feedback on: ...

Our Speed Cameras are Working: Initial Evaluation Shows Drivers are Slowing Down By Nick Veronin Six months after the first speed cameras were installed in San Francisco, our studies show drivers are slowing down. It’s been six months since the first cameras in the SFMTA’s Speed Safety Camera Program were activated. In that time, we have seen a major decrease in speeding on city streets equipped with automated speed enforcement cameras. Today, we are releasing the data from our most recently completed speed study. The study analyzed speeding at 15 key locations before and after we installed our cameras.

Show HN: Spit Notes – A songwriting app that keeps lyrics and audio together Any songwriter who uses the iOS Notes app to write their lyrics has a mess of New Recording 142 voice memos in their Voice Memos app. I made Spit Notes as basically the Notes app but with a built-in voice recorder that keeps your audio files neatly organized on the same line as your lyrics. Now you can quickly capture your song ideas while driving or when you wake up in the middle of the night without worrying about losing them in your pile of untitled voice memos. While you can attach audio to notes with other apps, adding and recording audio has a lot of friction, and often the layout of the audio elements in those apps are too pronounced to keep the text flowing seamlessly. This is not the case with Spit Notes. I've wanted this app to exist for years but I put off making it myself because I knew it would take me a lot of time to build manually without knowing Swift. In recent years I've been writing...
