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!

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

The rails of commerce should be public infrastructure, not private monopolies

It’s a modern cliché: you mention wanting new running shoes or a vacation, and suddenly you’re drowning in ads for them everywhere you go online. It feels like the internet is eavesdropping — because, in a way, it is.

Our online intentions — what we want to buy, do, or learn — are the most valuable signals on the web. Google, Meta, Amazon, and a handful of others scoop them up, resell them in hidden auctions, and pocket the value. In other words, we’ve become the product.

This setup is as broken as it is creepy. Users lose control. Sellers pay rising “ad taxes” to reach us. Developers can only build inside Big Tech’s walls, or risk never being seen at all. Innovation happens only with their permission.

My team and I decided to stop just complaining about it and start building an alternative.

Here is the idea: What if your intent wasn’t captured behind your back, but declared openly — on your terms? What if sellers had to bid transparently to meet your needs, instead of targeting your profile? What if value flowed in the open, instead of getting locked inside platforms?

That’s the vision behind the Intents Protocol — a neutral, open layer where intent is declared, verifiable, and user-owned. Designed as public infrastructure, it’s built to be transparent and shaped by its community. 

And to prove it can work, we built our first experiment: Inomy, an unbiased AI shopping assistant. It’s designed to save you hours of research and match you with what you want — without selling you out. 

It’s very early. Probably buggy. Definitely rough. But it’s real, and live. And we’d be incredibly grateful if you’d help us stress-test it. Join the mission. Try Inomy beta here.

After a long hiatus from coding, I'm back to building in the open. Here's my new FOSS project: UndeadWallpaper for Android.

Hey everyone,

Check out the quick demo video on YouTube: https://www.youtube.com/watch?v=NEgmwFge-lM

I wanted to share my new open-source project, UndeadWallpaper. For me, this is a bit more than just an app. I had to step away from development for a long time, and this was the first thing I built to prove to myself I could still do it. It's simple, but the name is a symbol of my passion that came back from the dead.

It's an Android app that simply sets any video as a live wallpaper. It's completely free, with no ads, and the code is under the GNU license.

I'm happy to be building in the open again and would love any feedback from anyone.

You can find the full source code on GitHub: https://github.com/maocide/UndeadWallpaper

It's also available on the Play Store if you just want to check it out: https://play.google.com/store/apps/details?id=org.maocide.undeadwallpaper&pcampaignid=web\_share

P.S. I'll be sharing updates, future projects, and my development journey over on X if you want to follow along: https://x.com/maoc1d3

nanokv – open-source distributed key-value store in Rust

Hi all,

I recently released nanokv, a small open-source distributed key-value/object store written in Rust.

The project started as a way for me to learn Rust + distributed systems. Along the way, I added:

replication with 2PC,
a coordinator + volume architecture,
operational tools (verify, repair, rebuild, rebalance, gc),
OpenTelemetry tracing + k6 benchmarks.

It’s not a competitor to MinIO, but a hackable, educational codebase that you can read through and run yourself. The repo has a detailed README with design notes and benchmark instructions.

Repo: github.com/PABannier/nanokv

Would love feedback, contributions, or just ⭐️ if you find it interesting!

bungaku - simple manga reader for Android

hello r/opensource,

I am looking for users, feedback, and contributors for a passion project i started which i am now comfortable enough to share to the public. bungaku is a simple manga reader for Android made with React Native and powered by the MangaDex API.

For features, i think bungaku has the basics down at least.
\- reading manga provided by MangaDex
\- 3 modes of reading (webtoon, horizontal, vertical)
\- A means to search for mangas with filters
\- downloading chapters and reading them offline

with all these features of course, bungaku is still in its early phases of development there may be sneaky bugs. and compared to other readers like NekoReader (which also uses MangaDex's API) bungaku admittedly falls very short. however, i started this project as more of a study in React Native as I like its way of doing things and a study of UX design.

so please, if you are interested, feel free to download a release and maybe even contribute! thank you!

Built Zeno - A plugin-first markdown blog framework (need feedback!)

Hey folks 👋,

I’ve been hacking on a side project called Zeno \- a lightweight, plugin-first Markdown blog framework written in JavaScript.

The idea is simple:

Write posts in plain `.md` files with frontmatter
Use simple folder-based themes (post.html, index.html, style.css)
Extend with plugins (`onMarkdownParse`, `onRenderHTML`, `onPostBuild`)
Ship a blog with just one command

I just pushed the first version live:

📖 Docs: [zeno-docs.vercel.app](http://zeno-docs.vercel.app)
💻 Repo: github.com/mine3krish/zeno

It’s still early & experimental, but already supports:

`zeno init` → scaffold a new blog
zeno build → generate static HTML
`zeno serve` → local dev server
Basic themes, tags support, and plugins

⚡️ I’d really love feedback from open source devs — what features would you expect in a modern blog framework?
Also curious if anyone would be interested in contributing (themes, plugins, docs, etc).

Thanks for reading 🙏

A company approached my open-source project pretending to want to help open-source projects, then stole the idea and launched a competitor!

Hello all,

I'm the creator of Puter, a project that I open-sourced here on this very sub-reddit with your incredible support. I've often said that open-sourcing my project was one my life's best decisions and I owe it all to this incredible community.

Since open-sourcing in March 2024, it's been mostly a huge blast and being a high-growth OSS project you often experience companies approaching you with ideas and offers. One of those companies that approached me a few months ago is Merit Systems, a VC-backed (crypto?!) startup with $10m funding. They set up a meeting with me under the pretence that they are building a platform for OSS projects helping them attract and fund contributors. I was cautiously optimistic about the idea and we set up a few more meetings. They kept asking more and more about my vision and how I'm thinking about expanding or even commercialization etc, which I found odd but didn't think much of it.

I eventually decided not to use their platform since I was a little hesitant about using crypto etc in our project, especially if the platform is not OSS itself. I thought that was the end if it but fast forward to last week they announce a product exactly like our SDK, which has nothing to do with their core product. So they decided to simply take our idea and turn it into a competing product :-/

They're using crypto tactics to create hype around the product by paying crypto accounts on twitter to post about the product. Even worse is that they seem to be buying stars to prop up the project: https://github.com/Merit-Systems/echo/stargazers It's pretty demoralizing to watch this especially since I basically got tricked into sharing my vision with them because I genuinely thought they were building a platform for helping open-source projects.

I'm sharing this experience as a cautionary tale. If you're maintaining an OSS project, please be careful when discussing your vision (even though being open-source there isn't many secrets anyway lol), especially those that seem more interested in your vision and details than in genuine collaboration. Trust your instincts when something feels off, and remember that not everyone approaching our community shares our values of openness and genuine innovation.
