How to make Dev containers work for vscodium flatpak

Hi All,

I've been using the vscodium flatpak for a while and am very happy with it. However, I've recently been trying to spin up a dev container and run into a bit of a brick wall.

As this is Vscodium the dev-containers plugin is out as that's propriety to microsoft and therefore only available to VsCode users. No bother, containers tools is open source and podman and pod-manager are open source. However, due to the isolation of the flatpak all the tutorials I can find then use vscode's remote development plugin, which is again a proprietry Vscode exclusive, to connect to the container.

Is there an open source alternative I can sub in for the "remote development" plugin or some other way I make dev containers work on the vscodium flatpak.

Thanks,

Looking for projects to contribute to (French translator)

Hi all! Sorry if maybe slightly off-topic, but I'm looking for some cool projects to contribute my translation skills to. I've got over 3 years of professional translation experience (French to English and English to French) for a big company in the UK under my belt and I've currently got some spare time, so would love to help out!

Any ideas of where I should look for any such projects? Feel free to link me to anything interesting and open source that's looking for help! :) cheers!

I built a community-driven list of free & open APIs with examples – looking for contributors!

Hey everyone,

I just launched a new open-source project on GitHub: [**Awesome Open Data APIs**](https://github.com/Humayun-glitch/Awesome-Open-Data-APIs) 🚀

The goal is simple:
👉 Create a **community-driven collection of free & open APIs**, neatly categorized (Finance, Weather, Space, Education, etc.), with **examples** in Python & JavaScript so anyone can get started quickly.

Why?

* Finding good free APIs is often a pain (outdated lists, broken links, no examples).
* This repo is meant to be a **living, maintained resource** for developers, students, and hobbyists.
* Anyone can contribute new APIs, fix broken ones, or add examples – beginner-friendly PRs are welcome.

📂 Repo includes:

* Curated list of APIs by category
* Example code snippets (Python & JS)
* JSON files with structured API metadata
* Easy contribution guidelines

If you know a cool free API, please consider adding it! 🙌

🔗 GitHub Repo: [github.com/Humayun-glitch/Awesome-Open-Data-APIs](https://github.com/Humayun-glitch/Awesome-Open-Data-APIs)

I’d love your feedback – what categories or features would make this the most useful for you?

Thanks!

Built a tiny Go string-case lib (sx) + looking for project ideas 👀

Got bored and hacked together a small Go lib: https://github.com/gomantics/sx

It’s basically string case utils (camelCase, snake_case, kebab-case, etc), inspired by scule from unjs.

Thinking of doing more little weekend libs. I feel like Go’s missing a solid OAuth2 server library (esp. for MCP OAuth servers), but I’m open to other ideas too - maybe even some small full-stack apps.

Would love feedback on sx + any ideas you think the Go world needs 🙌

May be this is just me prepping for hacktoberfest 😂

How to contribute to OpenSource projects? Is there a chance for a beginner in 2025?

I am a complete beginner in opensource and I've tried contributing but always got confused from where to start. I know that every beginner should start with 'good first issue' labelled projects but there are already so many contributions in those. So how should i approach it?

Built a tiny c++ text chunker for python

Hey people! I've been working on a project that involved working with large texts and I've been forced to build a c++ implementation of a chunker in order to be fast and I eventually decided to extract my code and build a pypi package!

And I'm happy to share it to the open source community https://github.com/Lumen-Labs/cpp-chunker

I know It's a small package but I would love to hear your thoughts

Is there an open source program that could take large PDFs and read them aloud using an AI TTS?

I've been poking around a little bit on this topic for a while but most of what I find either uses really old TTS models that sound terrible or struggles to deal with PDFs longer than a few pages. I am not super techy but I have an alright understanding of computers. I am currently running windows 11. If programs only exist for linux, I've dual booted in the past, but I would rather not set that up on my current laptop.

What are some examples where working class people are empowered by open source?

I'm trying to find ways to promote open source projects and concepts to masses by generating points that could captivate a non-open source using audience. My target audience is working class people, and empowering them with open source tools and ideas.

One of my ideas is to start some social media following, or web series. I follow a handful of YouTube channels about Linux and open source, but I'm hoping to come from a different angle.

What are some good and empowering reasons why people should use open source? What are some of the caveats to why people don't use open source?

Open source not being mainstream, being difficult, requiring more tech literacy and experimentation, are barriers I'm well aware of. These caveats would be recognized in my content creation. I can think of a few off the top of my head, but I'd appreciate peoples' feedback or ideas on things that should be talked about.

I'm also churning out ideas on a local LLM AI, but I'd appreciate any input!

Building a secure and open note taking app

Hey r/opensource wanted to show off a secure and open note taking app we’ve been working on for a couple years:

https://github.com/lockbook/lockbook

our core values:

- everything end to end encrypted

- open formats: markdown and noscript

- strong offline support

- everything open source

- native apps where possible

- rust where possible

If you like video as a format I plan to regularly upload here: https://youtu.be/8LM5zrXiki8

Seeking Contributors (or just advice...) for single-page Rain + Wind velocity webapp

[https://rainornot.sporadicinsights.space/](https://rainornot.sporadicinsights.space/)

[https://github.com/Tenelia/rain-or-not](https://github.com/Tenelia/rain-or-not)

Hey all, I just wanted a predictive single webpage that can be 100% cached on your phone, which does the following:

1. Check rainfall at stations within radius
2. If no significant rain (< 3mm at included weather stations): Stop processing, inform user.
3. If significant rain detected: Fetch wind direction and wind speed data for vector calculations.
4. Convert wind data to normalized velocity vectors.
5. Store vectors in browser storage for persistence based on API's refresh rate.
6. Calculate if rain will reach user location within 15 minutes or other specified time.

After googling a bit, I've copied these maths formulas used by the threaded workers for all weather stations data multithreading calculations:

* **Distance**: `d = R × 2 × atan2(√a, √(1−a))` where `a = sin²(Δφ/2) + cos φ₁ × cos φ₂ × sin²(Δλ/2)`
* **Wind Vector**: `v⃗ = (|v| × cos(θ+180°), |v| × sin(θ+180°))`
* **ETA**: `time = (distance / effective_velocity) × 60` minutes

Current issues:

1. Singapore API data are served at 5 mins intervals, but I want to make my API endpoint agnostic, so anyone can plug their API in whilst on their phone...
2. The Haversine formula that was used in this case for circle distance calculation for station proximity filtering doesn't seem to work correctly... It always seems to be unable to catch incoming rain (at this point, I suppose you might ask why not just look up overhead?)

Sonnet and basic linting cleaned up obvious mistakes, but I'm out of ideas for now. Just want to receive guidance and pointers (or contributors!)

This repo solving backend system complexity with unification

I am a moderator and working on Motia, so why did we build this framework? We had a use-case for which we had to use APIs with Express, Sattes in Redis, Queues in BullMQ, and Workflows Agentic stuff with Temporal/Agno, etc, which is like working between different frameworks to build a complete backend system. So we thought there could be a solution where we stick multiple tools in different languages to create a complete backend system. You can let us know your feedback. It's an open-source framework available on: https://github.com/MotiaDev/motia
