Hi, in the last ~month I've learned a lot about ECS [1,2]. I'm currently developing a robotics simulator from scratch (python+raylib) and, due to lack of game dev experience I went "full OOP" on it. A SceneObject with a lot of inherited interfaces (e.g. Collidable, Movable etc.). These are inherited and fixed at run time. The main loop inevitably became: for scene_object in sim.scene_objects: scene_object.update(...) for scene_object in sim.scene_objects: scene_object.draw(...) Well, it turns out that this can become a bottleneck if you have many scene objects because computers love…

Hi everyone! I just released the Practical Python Projects book! (https://practicalpython.yasoob.me) I am happy to announce the first version as a release candidate. I have poured a lot of love into writing this book and would love to hear what you guys think. (A limited 100% off and discount coupons at the end) This is not a pure beginner book. The book does assume some background Python knowledge. You need to know the basics like methods, functions, classes, and such. If I use something that is not typically covered in beginner Python books, I will explain it before I use it.…

This is a little project I've been working on for a while in order to better learn Python. Although IRC may not exactly be the most exciting medium, I still find it to be fun and useful, this interest lead me to writing a bot. In doing this I realized that what would actually be more interesting would be if I had a framework. There may already be such a thing, certainly there are IRC libraries, but I don't know if they're well-suited to deploying bots. At any rate if for no other reason than the fact that I am relatively new to programming and eager to learn I decided to build a framework.…

This is a Python (with Rust backend) library for high accuracy orbit calculation of the entire known catalog of asteroids. It is a full N-Body integrator, including lots of additional physics, such as relativistic effects, non-spherical gravitational fields of planets, masses of large asteroids, and a number of non-gravitational forces such as radiation pressure. The design goal is essentially JPL Horizons on your laptop, but all asteroids at once. I began this project while I worked at Caltech on a NASA mission called NEO Surveyor (which is a space telescope designed to survey Near Earth…

Hi everyone. I've recently released control-components, a C++ library I've been using for most of my embedded projects. It is written in C++17 (with some features from C++20) and uses STL and FreeRTOS under the hood. It contains a lot of building blocks that is commonly used in embedded and IoT projects: finite state machines (FSM), various counters, synchronisation primitives, system loops, sensors, schedulers, HTTP, WiFi, Web GUI, and much more. It also provides GitHub CI workflows for build automation (ccache, various checks). In general, it's a good starting point for an ESP32 project.…

Hi HN, I’m working on an experimental 3D FPS game engine in C++20, aiming to deeply understand engine internals from first principles rather than just using existing frameworks. Currently I'm strictly following LearnOpenGL docs. This project focuses on: Entity-Component-System (ECS) architecture for high performance. OpenGL 4.1 rendering with a PBR pipeline, material system, HDR, SSAO, and shadow mapping. Modular systems: input, physics (Jolt), audio (miniaudio), assets, hot reload. A sample FPS game & debug editor built into the repo. Repo:…

I built a small demo showing a robotics runtime executing entirely inside the browser via WebAssembly. The example workload is a simple flight controller hooked up to a small world simulator. The runtime comes from copper-rs, an open-source robotics runtime written in Rust for deterministic workloads. While robotics stacks are often tightly coupled to specific OS distributions and environments, here, the same code runs on microcontrollers (for example this flight controller also compiles for STM32H7 and flies real drones) as well as on desktop OS targets like Linux, macOS, and Windows. The…

Hey folks, wanted to show this off and get feedback. Still early/experimental but there are quite a few concepts I'm excited about here. This project came about while writing a program in Go and loving its approach to concurrency. Being a long-time Rubyist I immediately started to think about what similar concepts might look like in Ruby. I set out with two main design constraints: 1. Lightweight: I didn't want routines to be backed by fibers or threads. Having been involved some in the async project (https://github.com/socketry/async), I had some experience using…

Library makes requests asynchronously across models, so you can spend a lot of $$ quickly if you want XD. But seriously I hope this enables folks to create and run evals (especially safety ones) a lot easier than before.

Google Docs for Python basically. For the past 4 months, I’ve been working on a full-stack project I’m really proud of called PyTogether; a real-time collaborative Python IDE designed with beginners in mind (think Google Docs, but for Python). It’s meant for pair programming, tutoring, or just learning Python together. It’s completely free. No subscriptions, no ads, nothing. Just create an account, make a group, and start a project. Has proper code-linting, live drawings for note-taking or teaching, voice chat, an extremely intuitive UI, autosaving, and live cursors. There are no limitations…

A little game I made to show off an old project. The functionality of the CPU is derived entirely from simulated logic gates. All the operations and control flow are based on the underlying properties of the logic gates, and changing their operation leads to corresponding changes in function. The original game code is all python and it runs in the browser using wasm/pyodide. Not very mobile friendly

As a beginner learning to build ML models, I found it annoying to have to keep printing tensor shapes every other line, having to step through the debugger to check where did I mess up the shapes again. So I built Trickle, it takes the data that flows through your code, caches the types and display them inline (as if you have type annotations). The idea is: "Let types trickle from runtime into your IDE". You get types in Python without having the write them manually. It works by rewriting your Python AST at import time — after every variable assignment, it inserts a lightweight call that…

I've been building a C++ tensor library that tries to bring the ergonomics of NumPy/PyTorch to native code. The main goals were: - Familiar API (operator overloading, method chaining, same function names) - Actual GPU acceleration via Metal (not just matmul, but all ops) - Cross-platform with SIMD on x86/ARM/RISC-V via xsimd - einops-style rearrange/reduce patterns It started because I wanted NumPy's API but needed to deploy on edge devices without Python. Ended up going deeper than expected (28k LOC+) into BLAS backends, memory views, and GPU kernels. Some things I'm…

I've created an in-browser Python/Pandas/Git practice environment for my online learning platform and also for my corporate training classes. I'd be happy to discuss how I went about designing this, how I'm using it in my classes, and the architectural decisions I've made. Most interesting, to me, is how much is running in the browser. Thanks to Svelte, Pyodide, isomorphic-git, LightningFS, and CodeMirror I'm able to provide a full environment for Python, Pandas, and Git. I built much of this with Claude Code, and I'm happy to discuss how that went — what worked well and where I…

In the past 4 years, we developed a platform generating 3D visuals and deploying AR Try-on experiences into large footwear and retail companies. We focused on high-fidelity meshes and textures since the point was giving shoppers a realistic visual. Then robotics companies started to approach us and they asked for thousands of 3D assets that they can use in creating different simulation environments. This is crucial for them so they can achieve better sim-to-real transfer with domain randomization (train a humanoid in a million different kitchens so a real one is not a surprise when it is…

I have built many AI agents, and all frameworks felt so bloated, slow, and unpredictable. Therefore, I hacked together a minimal library that works with JSON/dict/kwargs definitions for each step, allowing you a simpler way to define reproducible agents. It supports concurrency for up to 1000 calls/min, giving you speed and predictability in your workflows. Install pip install flashlearn Input is a list of dictionaries Simply take user inputs, API responses, and calculations from other tools and feed them to FlashLearn. user_inputs = [{"query": "When was python launched?"}]…

Hi HN, I'm the author of FastMCP, the most popular Python framework for building MCP servers. I've been really excited about MCP Apps for a while. I think letting a server ship a fully interactive UI directly into the conversation is one of the most compelling additions to the protocol. I wanted to make this a first-class experience in FastMCP, but I kept getting stuck on what it actually means for a Python framework to integrate with a frontend feature. The JavaScript ecosystem has extraordinary tooling for this. I didn't want to build a worse version of it just to stay in Python. What…

Hey HN, half a year ago we were building a feature where our users could trigger long-running jobs with the following requirements: (i) the job is provisioned by the user action (e.g., clicking a button in the UI), (ii) the job can be canceled by the user, (iii) the progress of the job can be inspected while the job is running, (iv) hardware for the job is provisioned only when needed (the job may require expensive hardware and isn't called that frequently). Because we couldn't find any existing ways of achieving this we decided to implement one for Python. Currently, it uses an AWS ECS…

Hey all, Just reposting after about a year since the last time I shared. Micro is a platform for API development. It combines a lot of the core primitives you'd expect from a cloud platform as a single logical server. The closest equivalent is Dapr.io. It bakes in the concept of environments, source to running builds and a framework for Go development. It's useful where you want to write backend services in Go and expose them through a single API (also included in Micro). We once wrote about "Netlify for the frontend, Micro for the backend"…

Hello HN, Pietro here! I've been really excited to see the recent buzz around MCP and all the cool things people are building with it. Though, the fact that you can use it only through desktop apps really seemed wrong and prevented me for trying most examples, so I wrote a simple client, then I wrapped into some class, and I ended up creating a python package that abstracts some of the async uglyness. You need: * one of those MCPconfig JSONs * 6 lines of code and you can have an agent use the MCP tools from python. The structure is simple: an MCP client creates and manages the connection and…

actually, nothing special about this implementation. just another event loop written in rust for educational purposes and joy in tests it shows seamless migration from uvloop for my scraping framework https://github.com/BitingSnakes/silkworm with APIs (fastapi) it shows only one advantage: better p99, uvloop is faster about 10-20% in the synthetic run currently, i am forking on the win branch to give it windows support that uvloop lacks
