Need feedback, contributors & users for my open source python IoT runtime (HTTP, MQTT & ZMQ supported)

Hi all, about 1-1.5 years back, I released a (fully-)permissively licensed open source implementation of an IoT runtime in python. Its supposed to be beginner-friendly as well as suitable for learning some formal ideas about hardware control without compromise. Its not a tool or vendor-locked implementation, its a runtime that helps you write code that control your hardware.

You can find it here: [https://github.com/hololinked-dev/hololinked](https://github.com/hololinked-dev/hololinked)

The salient features are:

* protocol & content type agnostic (HTTP; ZMQ & MQTT supported currently for protocols, JSON, message pack, pickle for content types), can be extended to other protocols or content types
* interoperable and cross platform
* supports three interaction with devices named as properties, actions and events, and a state machine.

One can use it, for example, in a home automation project on a raspberry pi or lab automation in a science or electronics lab (which is what I use it for - for example, you have a spectrometer or a camera in your physics lab, or a power supply or oscilloscope in your electronics lab)

Its coming very close to becoming production ready, I need to add more compliance related stuff like security scanning, dependency scanning etc.

In meanwhile, I am looking for feedback, users and contributors. Please have a look and I would be interested to hear from you. There are also a limited number of good first issues. I am also open to PRs with new features that you may find interesting.

I built an open-source Shell-Commands Manager

### GitHub: Here

#### Hey everyone!

I've been developing a modern command manager called CMD Manager, that allow users to manage and run commands easily. I'm relatively new to QT5, so any contribution and feedback is greatly appreciated!

Available on both Windows and Linux!

#### Why Did I Build This? (Target Audience)

I have to memorize and run a lot of commands in the command shell. Sometimes important bash noscripts gets lost in my files. To manage all of the commands, I created this application, allowing users to save and run a lot of commands easily.

There is a cool feature that I use often, which is replace placeholder file, that allow user to substitute the placeholder file inside the command (input.txt) and choose the actual file from the computer system easily (C:\Documents\project\abc\data.txt). There are also a lot of fun themes and font customization to choose from! Also available in 6 languages! (Feel free to add more!)

What's your take on AI in project management tools?

Seems like every PM tool is slapping "AI" on their landing page now, but most of it is just glorified autocomplete. Has anyone actually found AI integration that's genuinely useful for managing projects? Or is it all marketing hype?

Released My first open source project - A universal database seeding tool

Hi r/opensource members!👋

I just released my first open source project and wanted to share it with this amazing community.

🧩 Project: quick-seed
📜 License: MIT
🛠️ Tech Stack: TypeScript, Node.js




# 🚀 What it does

A CLI tool that generates realistic test data for databases, without writing custom seed noscripts.
It works seamlessly across PostgreSQL, MySQL, SQLite, Prisma ORM, and Drizzle ORM.



# 💡 Why I built it

I was frustrated with maintaining different seeding approaches for every project.
quick-seed provides a universal solution, one schema file works everywhere.



# 📚 What I learned

Publishing to npm
Building a CLI with Inquirer and Yargs
Working with multiple database adapters
TypeScript packaging and exports
Writing comprehensive documentation



# ⚙️ Current status

✅ Published on npm (v1.0.9)
✅ Comprehensive README with examples
✅ Supports 5 databases/ORMs
✅ Auto-detection for Prisma and Drizzle
🔄 Working on: Auto-generating schemas from existing database structures



# 🤝 Looking for

Feedback on the API design
Suggestions for new features
Contributors (especially for new database adapters)
⭐ Stars if you find it useful!



📦 npm: @miit-daga/quick-seed
🔗 GitHub: https://github.com/miit-daga/quick-seed
📚 Docs: Available in the README



This is my first contribution to open source, so any advice on project structure, documentation, or community building would be greatly appreciated! 🙌

Invoice and BookKeeping (and more soon)

Hi, I'm with Tridah, a Non-Profit making Open Source (Github + MIT License). But we want to host these tools too (So for those who struggle setting up self hosting or unable to can also access them!)

I'm working on merging individual applications I've made into what I'm calling TridahDrive
I want to get initial impressions on the app though.


The idea is that it works kinda like Google Drive. You have your personal drive but can create 'shared' drives and add people to it.

Invoces/Bookkeeping and future tools will be specific to that drive or 'org'

I'd love to get initial impressions / feedback on the tools / suggestions to improve them etc.

You can access it here: https://drive.tridah.cloud
I have set up a fresh test account:
Email: test@tridah.cloud
Pass: Tester123

If you'd like to contribute or make your own version/self host:
https://github.com/TridahCloud/TridahDrive

We're always looking for volunteers too (I'm doing it all solo right now, the other board members aren't technical and purely administration). Help with development, documentation, project management, server admin etc are all highly welcomed!

Would you use an open-source tool that gave "human-readable RCA" for pipeline failures?

Hi everyone,

I'm a new data engineer, and I'm looking for some feedback on an idea. I want to know if this is a real problem for others or if I'm just missing an existing tool.

My Questions:

1. When your data pipelines fail, are you happy with the error logs you get?
2. Do you find yourself manually digging for the "real" root cause, even when logs tell you the location of the error?
3. Does a good open-source tool for this already exist that I'm missing?

The Problem I'm Facing:

When my pipelines fail (e.g., schema change), the error logs tell me where the error is (line 50) but not the context or the "why." Manually finding the true root cause takes a lot of time and energy.

The Idea:

I'm thinking of building an open-source tool that connects to your logs and, instead of just gibberish, gives you a human-readable summary of the problem.

Instead of: `KeyError: 'user_id' on line 50 of transform_noscript.py`
It would say: "Root Cause: The pipeline failed because the 'user_id' column is missing from the 'source_table' input. This column was present in the last successful run."

I'm building this for myself, but I was wondering if this is a common problem.

Is this something you'd find useful and potentially contribute to?

Thanks guys !!

Calling all OMSI (Bus Simulator) QoL enthusiasts. Let's build the definitive, simple, offline-only navigation overlay. (Volunteer effort, FREE for all)

Hey everyone. I'm new to gaming in general, and after just two weeks of getting into OMSI 2 (bus simulator), I'm already completely done with the terrible in-game route arrows. It's genuinely surprising that such a great simulation game has such a frustrating navigation system, and it's a huge drawback for solo drivers.



Like many of you, I play the game alone most of the time. I'm aware there are existing addons, but personally, I'm looking to build a lightweight, strictly offline alternative. This project is specifically designed for people who don't want or need the online/multi-user features of things like Omninavigation.



I just want to see a simple, clean display showing the map, the route I selected, and a clear guide to the next few bus stops.



So, I'm starting a focused, casual, volunteer collaboration to fix this long-standing community pain point. We need people who want a fun side project to help polish their skills and deliver a major quality-of-life mod: We're looking for:



\- Coders

\- Designers (for simple, clean UI/UX of the display)

\- Dedicated testers (to break the system on every map!)



If you’re a hobbyist looking for a high-impact, free project for your portfolio, or just someone who loves OMSI 2 and wants to leave your mark, DM me. Let's build the best free navigation tool out there for solo drivers.

My first serious open source app just got a huge update!

Hey everyone!

A few months ago, I shared my first serious open-source project here - Aniki, a desktop app for managing and watching anime.

https://github.com/TrueTheos/Aniki

Recently, a friend suggested adding some shields to the README, and turns out Aniki had over 1000 downloads (it currently shows around 500 because I removed some older releases). I honestly thought the only users were me and my friend.

I decided to completely rework the app, I’ve redesigned almost everything, including the UI, and made major backend improvements.

As before, I’d really appreciate any feedback on the code, and I’m also looking for contributors and users who might be interested in testing or helping out.

Can’t wait to hear your thoughts and fix everything that's wrong with it :)

What software do you use for forms?

For me, shareable forms are a necessary, important and constantly needed tool. Instead of constantly working with PDFs or (God forbid) Word documents, a form that can be called up in the web browser would be the very best solution. If, in addition to a database, it could also flow into a table (as with Google Sheets / Forms), even better. Grist: only a rudimentary form system, Wordpress as well, https://www.opendesk.eu/de probably via Nextcloud plugins or similar, which is also not so great.

How do you do that? Always build yourself in html with extra backend? Or is there a good opensource solution that I missed?

Is China’s Open Source AI Race Changing the Global Tech Landscape in 2025?

I just read an eye-opening article about how China is aggressively pushing open source AI development — faster than many expected — and what it could mean for innovation, global competition, and the AI market overall.

Some key takeaways:

* China’s focus on open sourcing AI models is accelerating adoption and innovation domestically
* This shift could disrupt the US and Europe’s traditional AI leadership, especially in key sectors like healthcare, finance, and manufacturing
* Open source also means more collaboration but raises questions about security and ethical oversight

What do you think? Could China’s open source AI initiatives reshape the global AI race? How should companies outside China respond to stay competitive and innovative?

Would love to hear your insights or experiences related to open source AI, especially in emerging markets.
