I've been working on this 3D N-Body simulator, quite by accident.

I started working focused more on a game - but ended up creating quite UI for a multi-camera view of the simulator.

It's still "early release" - but overall it's quite stable now. I've added docs and there is a tour of the functionality when you first load the app.

Hey,

I have a platform to test and improve prompts, with observability. It has its own SDK.

I'm thinking to add in the context of the model rules, like:

You have next skills:

``` - web_call({'query': '...query'})

- make_plan({"step1": {"expected_results": "", actions: "", "where_we_are": }})

- update_plan("step_name": {"expected_results": "", actions: "", "where_we_are": })

If you wish to make a call you need to make a call:

{

"tool_name": "",

"parameters": { // parameters of the tool },

}

```

----

It's a prompting technique which i use for models like deepseek. But, I wonder if ppl here are interested to have a python lib which will support MCP in the same similar way with all other models, not just Claude, and it will help to choose easily which model performs best for your task. w/o marriage to Claude models.

Hello HN!

I've been an active Leetcode user for a long time and while I think it's a great platform to test your skills, I've never really considered it a good resource for learning. Whenever I'd get stuck on a question I'd just look up the answer then try to understand it via reverse-engineering which never seemed very efficient to me. That's why I built HinterviewGPT.

HinterviewGPT started as a side project where my initial idea was to build a UI that looked a lot like leetcode with the question on the left and the editor on the top right, but have a chat UI on the bottom right where you could chat with an LLM-based "tutor". The "tutor" would be aware of the question and your current solution in the editor and it would be instructed to answer your questions when you are stuck by giving hints and specifically NOT instructed to give you the answer (otherwise it wouldn't be a very good tutor).

I built this side project and it worked surprisingly well. The tutor's hints guided me towards the correct answer conversationally rather than me having to look up the correct answer when I got stuck. This really made my learning more efficient and cut down on my study time per question. It also promotes "active learning" (learning through hints) rather than passive learning (trying to reverse-engineer the solution) which I think made the learning stick more. As a result I decided to build this into an actual product.

For the product I added a "question generation" feature. Via another chat UI you can describe the kind of question you want to practice (based on industry, role, topic, job req, etc.) and HinterviewGPT will generate a question for you which you could then practice. So you don't only have to study leetcode questions with HinterviewGPT, you can really study any kind of interview question. You can also study both code-based and text-based (e.g. behavioral, system design, etc.) questions. Or if you have a particular question in mind that you want to study, you can manually enter the question as well. Once you're done practicing the question you can submit it for a final evaluation and your solutions and evaluations are saved for future reference (again, like leetcode).

Here's a demo of the full workflow i.e. question generation, practicing with tutor, submitting your solution: https://www.youtube.com/watch?v=Yj6qvEQYWi0

All the LLM-related features use OpenAI models under the hood specifically gpt-4o-mini, gpt-4o, o1-mini, o3-mini. You can choose when to use which model. gpt-4o-mini does suprisingly well in a lot of cases but obviously for more complex questions the more advanced models are preferable.

HinterviewGPT offers a free trial (with only gpt-4o-mini is available unfortunately).

Note: don't take this as me endorsing leetcode-style interviews, I actually don't like them at all or think they are effective.

Hey HN,

I built Commuter because I was tired of switching between different apps to check arrival times for BART, Caltrain, Muni, ferries, and more. This app pulls directly from the official 511 API and aims to provide a fast, clean experience focused on real-time departures.

There’s no account creation, it’s free to use, and it supports every major transit provider in the Bay Area—from Napa down to San Jose. You can search, favorite lines/stops, and see live countdowns with minimal friction.

It’s built entirely in SwiftUI using native Apple frameworks.

Happy to answer questions about the API, SwiftUI quirks, or anything else. Feedback welcome!
