What features would you want in an open source learning app?

Hey r/opensource,

I’ve been working on a project called Mnemo for 2 years now, a free and open source study app aimed at making learning tools accessible to everyone. The programming started two weeks ago (no downloads yet), but the website is up with details, UI showcase, and the philosophy behind it: https://shadowccs.github.io/mnemo-site/

The big ideas behind Mnemo are:

No expensive subnoscriptions for basic learning tools
Fully open source & customizable
Private by default, your data stays with you
Feature development guided by learners, not corporate priorities

I’d love your thoughts on:

Is this something you’d find useful?
What features would you want in a study tool like this?
Anything that feels missing from the concept?
Anything specific you find lacking from other tools?

This isn’t meant as a promo, more like a sanity check before I dive deep into coding.
I really want feedback from people who value open source principles.

Thanks for reading!

We just made Loadouts for Genshin Impact available as an RPM package in the official Fedora Linux repositories - v0.1.10 being the first release there!

# TLDR

Besides its availability as a [*repository package on PyPI*](https://pypi.org/project/gi-loadouts/?ref=gridhead.net) and as an [*archived binary on PyInstaller*](https://github.com/gridhead/gi-loadouts/releases/tag/0.1.10?ref=gridhead.net), Loadouts for Genshin Impact is now available as an [*installable package on Fedora Linux*](https://src.fedoraproject.org/rpms/gi-loadouts?ref=gridhead.net). Travelers using [*Fedora Linux 42 and above*](https://bodhi.fedoraproject.org/updates/?search=gi-loadouts&user=t0xic0der&ref=gridhead.net) can install the package on their operating system by executing the following command.

$ sudo dnf install gi-loadouts --assumeyes --setopt=install_weak_deps=False

# About

This is a desktop application that allows travelers to manage their custom equipment of artifacts and weapons for playable characters and makes it convenient for travelers to calculate the associated statistics based on their equipment using the semantic understanding of how the gameplay works. Travelers can create their bespoke loadouts consisting of characters, artifacts and weapons and share them with their fellow travelers. Supported file formats include a human-readable **Yet Another Markup Language (YAML)** serialization format and a JSON-based **Genshin Open Object Definition (GOOD)** serialization format.

This project is currently in its beta phase and we are committed to delivering a quality experience with every release we make. If you are excited about the direction of this project and want to contribute to the efforts, we would greatly appreciate it if you help us boost the project visibility by **starring the project repository**, address the releases by **reporting the experienced errors**, choose the direction by **proposing the intended features**, enhance the usability by **documenting the project repository**, improve the codebase by **opening the pull requests** and finally, persist our efforts by **sponsoring the development members**

Updates

[Loadouts for Genshin Impact v0.1.10](https://gridhead.net/loadouts-for-genshin-impact-v0-1-10-released/) is OUT NOW with the addition of support for recently released characters like **Ineffa** and for recently released weapons like **Fractured Halo** and **Flame-Forged Insight** from **Genshin Impact v5.8 Phase 1**. Take this FREE and OPEN SOURCE application for a spin using the links below to manage the custom equipment of artifacts and weapons for the playable characters.

I made a better Political Compass test

Hi guys, I was frustrated when doing the political compass, so I made a cool quiz called Votely.

It’s basically the Political Compass with more accuracy and depth, but still quick to take.

We’ve also been adding more features at the request of our users, including:

1. A progressive to conservative axis to capture social views
2. 81 ideologies instead of just four quadrants
3. percentage sliders from -100% to 100% for nuance
4. a very fun 3D cube you can spin around
5. short and long versions depending on how much time you have

Check it out at https://votelyquiz.juleslemee.com/ and let me know what you think! I’d love feedback on any features you’d like to see next.

The code is fully open source at https://github.com/juleslemee/Votely

Show HN: I open sourced my screenshot tool that i made for myself.

https://github.com/jellydeck/moocup/


features:

\- 3d transform, scale up and down image

\- Change position, scale

\- Apply fixed margin on all axis

\- Smart magic border, color, width

\- Single click export to Webp, PNG, JPEG.



you can also self-host by following instructions in Readme, or using Railway for single click deploy.

It's a personal tool I made for myself. I needed good photos to showcase my work, and all the available options felt quite right.

so i made one myself.

lemme know if you have any ideas for features.

Open Source to Business – Your Suggestions Needed

Hello folks,

I have developed an open tool designed to assist researchers and academics with article and literature research and search. My question is—how can I best leverage this tool from a business perspective?

My current plan is to launch it as a free tool for now, with frequent updates and new features in the pipeline. I would appreciate any ideas or suggestions you can share.

A free, open-source “computer freeze” tool?

I’m keen to hear everyone’s thoughts on building a program that can effectively “freeze” your computer so no changes are written to the drive.

Basically a modern version of Toolwiz Time Freeze (link to Wayback Machine). I have tried to reach the owners, but I can't find any recent contact information. My use case is for when we are sharing devices in a setting where Windows Enterprise is unrealistic.

I know Deepfreeze exists, but I would rather use something free and open source. My primary objective is to get a hold of someone at Timefreeze to ask for the code, but I don't know how realistic this is.

Pybotchi 101: Simple MCP Integration

# As Client

### Prerequisite

- LLM Declaration

```python
from pybotchi import LLM
from langchain_openai import ChatOpenAI

LLM.add(
base = ChatOpenAI(.....)
)
```

- MCP Server (`MCP-Atlassian`)
> docker run --rm -p 9000:9000 -i --env-file your-env.env ghcr.io/sooperset/mcp-atlassian:latest --transport streamable-http --port 9000 -vv

### Simple Pybotchi Action

```python
from pybotchi import ActionReturn, MCPAction, MCPConnection

class AtlassianAgent(MCPAction):
"""Atlassian query."""

__mcp_connections__ = [
MCPConnection("jira", "http://0.0.0.0:9000/mcp", require_integration=False)
]

async def post(self, context):
readable_response = await context.llm.ainvoke(context.prompts)
await context.add_response(self, readable_response.content)
return ActionReturn.END
```

- `post` is only recommended if mcp tools responses is not in natural language yet.
- You can leverage `post` or `commit_context` for final response generation

### View Graph

```python
from asyncio import run
from pybotchi import graph

print(run(graph(AtlassianAgent)))

Good resources for learning about managing open source and open source "business models".

I've started to soft launch my first open source project, which is a niche project tailored for a non-programming community.

I attended an event yesterday and I feel buoyed by the response I got. I had a link to a very basic version of my project at the event. My project was very well received and I feel as if I may be on to something. People seem really stoked. It's only one event, but I feel confident now that I can copy that success in getting buzz, and keep building the project and it will just get better.

I have NEVER done anything like this and I'm trying use this momentum while also building a roadmap in my brain of how to sustain and keep the ball rolling, while also keep the project from sucking.

I'm motivated to go open source rather than commercial because I think it'll be much much easier to build a community this way. There are plenty of commercial alternatives, but not really any stand out open source projects. I'm also a relatively green programmer (competent, but not a wizard. ~5 YOE building stuff).

The few questions on my mind now that I'm slowly making the idea public:

-Competiveness. Because it's open source, anyone can use and modify my code. Obviously this is a really neat part of open source. I also can't help shake the quiet instinct saying "what if someone steals it and builds something better and I get left out" or whatever.

-Monetization. I would be lying if I said I don't ever want to money from it. Given the availability of other commercial alternatives, I don't think monetizing the product itself is a winning strategy. I do think that if the project works really well and has a strong community, I can use that community to sell things, provide monetized support, build offshoot/complementary products for money, etc.

I want to make sure I do this in an ethical and honest way. If people are volunteering their time to contribute, even if I monetize something tangential, I'm still benefiting from these people's free work indirectly. The last thing I want to do is alienate the community because of how I personally benefit from their collaboration.

-Collaboration. Now that the product is starting to get "out there" a little bit, I do have some programmers and graphic designers who are starting to contribute small pieces. Now I need to built almost a secondary project for creating tickets, documentation, etc to make it really really easy to collaborate and contribute.

Anyways, I'm extremely excited by the project because it's been something I've been messing with for last five years. This project is more or less the reason I started programming in the first place. I thought "I wanna build that..." which motivated me to learn and go back to school for a MS, get better at math, etc.

I would be deeply grateful for any advice, resources, etc from people with more experience while I navigate these early questions. My mind is racing with ideas after this soft test launch, and my motivation for this project is as high as it's ever been.

SED: Open source semantic layer and AI-data firewall for safe, governed database access

Hey r/opensource!

I wanted to share a project I’ve been building called SED, an open source semantic layer and AI-data firewall designed to make AI-powered database access safe, governed, and compliant.

SED automatically analyzes your database schema to create a semantic layer that understands your data and business logic. It translates natural language queries into secure and optimized SQL while enforcing access controls, compliance, and governance rules dynamically. The system detects schema changes to keep everything in sync and operates entirely locally, ensuring your data never leaves your environment.

Essentially, it serves as a protective firewall between AI models and sensitive databases to prevent unauthorized or unsafe access.

If you’re interested in projects around AI, databases, and data security or if you’re building AI-native apps that query data ,I’d love for you to check it out, try the CLI tool, and share your feedback.

Here’s the repo: https://github.com/holy182/sed-cli

Warp Terminal is terrible, hear me out.

Heya, Sorry to say this, But i think Warp Terminal is terrible, Don't get me wrong, I really love the way it fully automates coding on your pc while you only have to give the prompt, But 150 ai requests a month without refresh every day? Come on, that's terrible, Having to wait 30 days for 150 ai requests, At least give us a day cap, Waiting 24 hours, i can deal with that, But 30 days? Good grief...

Do any of you know good alternatives for Warp Terminal?
