Who's looking for open source contributors? (September 17 edition)

Find something to work on or promote your project here.

Please shamelessly promote your project. Everyone who posted in previous weeks is welcome back this week, as always. ๐Ÿ˜„

Happy coding!

Did you find this post useful? Show some love!

Hey, all!

Me and my co-creator are preparing to open source our project, Heupr, which uses machine learning to help manage software projects. We built it entirely in Go and we'd love to have anyone who's interested join us in working on new features, migrating to a new codebase, and generally tinkering with some machine learning. Shoot us an email at heuprHQ@gmail.com if you'd like to be kept in the loop and I'll periodically drop in on Ben's weekly open source message as we prepare to open source.


Hi John, I am too interested in your project.I have sent you an email.

Hi John, I am interested in your project. I have sent an email to the above address :)

Hey guys! Still a very fresh project.

Building career roadmaps for newbie developers who need help picking a career path.

This is for the Spak.co community. Will be integrated with #301DaysOfCode for greater exposure. Will also be marketing the project via my social profiles to help gain awareness.


If you want to help newbies with their careers we'd love to work with you!

Take a look at the org roadmap. Then, do a PR on anything you feel you have the skills for :)

Need content, wire frames & views built out.


Hello Benjamin,
This is a space I am very passionate about and would love to help out. Career support is still one of the biggest problems out there, especially for new folks.

Awesome! Just added a little more info to the repo tonight.

This looks like a very promising project, the landing page looks really cool already. Didn't know about the #301DaysOfCode also, that's like 3 times the challenge I did haha

Thanks Juan :) Just added a little more info to the repo tonight.

Re-posting the same project from last week, since it sparked some interest among folks: Sail.

It is a Rails engine to bring in settings to control an application's behaviour while live.

There are two points I would appreciate collaboration:

  • Making the control dashboard design more elegant and better looking
  • Expanding the types of settings available

This time, I have created two issues as feature requests with implementation steps, if anyone is interested in contributing that would be a good starting point.

Suggestions and feedback are also appreciated!

Thanks a lot. We're definitely some of the folks interested.

And we'd probably get involved with Sail ourselves plus the community if it were live in dev.to.

In fact, I just made an issue requesting this, if you'd like to give it a shot Vinicius, we'd definitely love to have the gem's author active in our project.

Replace Flipflop with Sail #686

It may be silly to replace a tried-and-tested gem with a newer one, but conceptually I think this approach will work. Read on. Please mention if this would be a terrible idea.

Feature Request or Task

Sail is a new gem from a dev.to community member github.com/vinistock/sail

It adds app-wide settings/config in a way I like more than Flipflop. I feel like feature flags should live alongside other settings we might want to use. A unified site-wide admin config. This could also be a destination for a lot of features folks could use for self-hosted instances of the app.

User Story / Description

As an admin, I'd like to adjust a site-wide configuration.

Definition of Done

All current flipflop features are replaced by Sail, then we can add more as we go

This is awesome! I'm very flattered that you took such an interest in the gem.

I won't be able to get to the issue until the 25th (I will be out on vacation with little access to my computer), but I will gladly put together a pull request to add it to dev.to.

Then people can checkout to the branch and test it out, see if it suits your needs. Another idea would be to have the styling look like the overall dev.to design. That'd be pretty cool, I love the visuals on this site.

Anyway, I' m excited with the collaboration!

Awesome. Us or someone else may get to it sooner (or decide it isn't actually a good idea), but very happy with this approach and definitely excited to collaborate. Your involvement in both projects would be a real boon to everything!

Enjoy the vacation!!!

SBTCVM, a balanced ternary virtual machine project, which is written in python, is looking for developers with lower-level experience, interested in writing applications, games, ect. that are capable of running within the VM itself.

2 external programming languages are available:

  • SBTCVM Assembly: list-style assembler with automatic addressing, and a standard library of sorts.
  • SSTNPL: slightly higher level language with named integer variables, and goto-based subroutines.

Both of these support decimal in their syntax, so knowledge of balanced ternary isn't strictly necessary starting off.

Also, devs wanting to help with the VM, utilities, and compilers will need knowledge of python, and retro/embedded computing, the latter due to the VM's rather constricted specifications.

Devs should try and familiarize themselves with SBTCVM's basic features and principals, before trying to jump into the python codebase head-on.

python 2.7 and 3 compatible.

repo: github.com/SBTCVM/SBTCVM-Gen2-9
list of existing utilities and applications: sbtcvm.blogspot.com/p/utilities.html

Great Project ๐Ÿ‘๐Ÿ‘ I love CPU/Memory abstraction applications like VM's (i worked on YerliMilliVM for Kebablang. It process bytecode formed instrucationa that generated by KebabLang. Abstracts Memory, CPU and registers. github.com/BTaskaya/YerliMilliVM)

2 things may be improved:

  • Coding Style & Repository Structre
  • Docstrings instead of one line descriptions.

And forget Python 2 support. No one cares py2, it sucks.

firstly: its doing more than abstracting CPU and memory. its abstracting the very binary logic of the computer its running on. So naturally the code is going to get a bit on the complicated end of things. It has a full development toolchain, including 2 compilers, all custom built.

secondly: that codebase IS in alpha, and the repository structure is due to SBTCVM being designed as a self-contained, multiplatform package. The codebase is actually far better technically than its predecessor. using a modular design, with frontend code compartmentalized for easier development of additional frontends.

Thats not even mentioning the fact that the CPU is clocked at 6.5Khz. that might not seem like much, but that means the CPU parser is running 6500 times a second.

thirdly: python 2 support is staying until at least its EOL in 2020. That's my decision, and I'm sticking with it.

as for the coding style. I'm honestly more concerned with the modularity, maintainability, and speed of it, rather than how it looks.

still Gen2 is a massive improvement. Gen 1, as it was based on the first prototype, was much worse:

Hi all!

I'm working on a library to read and write PPM (portable pixmap) images with a simple to use C API. We have two out of three issues that prevented the first version of the library from being released fixed. Only one more issue needs to be resolved before version 1.0 is released.

Link to Github repository: github.com/Noah11012/libpixmap

Another project I've been working on is a C++ implementation of Rust's Enum Type Result. Not all methods found on Result are currently implemented and because of the language differences between C++ and Rust, not everything maps perfectly. If you would like to help me with this project it would be much appreciated.

Link to Github repository: github.com/Noah11012/result-for-cpp

Hi Noah! libpixmap looks interesting, but I don't see any open issues on the github repo. I understand that you have mentioned them in your README, but for better tracking, you could open issue(s) so that people can get more clarity on the task at hand.

They were placed in the README.md as the three issues blocking the first release of the library. Issues after the release of this library will be placed in the Issues tab.

I still don't understand as to how contributors can get more clarity on the issue. At least add a Contribution Guide, indicating -

  1. Things to be taken into consideration while making a contribution
  2. How to reach out to the owner(s) of the repository in case of any doubts.

I haven't thought about adding a Contribution Guide since the project is so small. If someone did create a pull request, I would format their code to my liking.

I've got a really simple JavaScript extension for Firefox that needs updating. It's got 15 open issues, and I know how to solve them but it would take a rewrite and I really don't want to spend time updating it. It's got 56 stars, over 4k users, and over 31k downloads on AMO, just under 60 5-star reviews, 4.8 on average, so I don't want to drop support.

If you or someone else likes WebExtension JS, HMU. I'll tell you what needs to be changed to fix those bugs and why it requires a rewrite.


I'm interested in learning more about extensions on Firefox. If you are open to giving some direct guidance to a newb then I'm definitely interested in contributing to your project. Also i looked and didn't see the label 'good first issue'; do you have that? I'll check again in the morning. You're project could be great way for me to learn! Thank you for sharing :)

I'm sorry, I don't really understand the second sentence. Could you reword that? Also, what is oscur? I would be glad to give help, even if I end up doing the rewrite myself.

Fixed. It was 1am and i was clearly exhausted ;)

Im interested but all that experienced with building extensions. So this will teach me a lot. Could help me tho on where to start?

Hi all!!! I just built a small library UI to react ... Re-jok is a React UI component library built with styled-components. It's a collection of components that help you design websites fast and beautiful easily. Now, it's very young, few components or somewhere looks like stupid but we always try to improve and add more components in the shortest time.

This's my repo: github.com/Tacaa/re-jok

Hi tranbathanhtung, I wanted to learn react for a while now, took some youtube courses, I think this will be good for me. email me at bassemmohamed1994@gmail.com

Plume is a federated blogging platform that aims to make it easier for anybody to start blogging. Users can host their own blog or use a public instance. It users ActivityPub for federation to improve discovery so your blog can be followed by any user of Plume/Pleroma/Mastodon/any other ActivityPub platform or RSS.

The project is written in Rust using the Rocket framework. Check out a public instance to get a feel for the platform or jump onto the issue tracker if you want to help.

If you would like to help by translating Plume, we also have a guide for you!

First link isn't taking me where i would have expected to go. I think it'sa link to GH notifications; I'm guessing since I'm on my phone.


I'm looking for open source project contribution. I have good skills in js ecosystem. If any one project maintainer here. I requested you to ping me.

Check out #jellyfin. @jonathan-irvin is the leader and posts under that hashtag frequently. We'd love to have you.

I'm teaching a class this semester at ITP / NYU called Open Source Studio. Contributions and feedback welcome in our GitHub Org. @ben willl be a guest speaker this coming Tuesday!

Also, for the second half of the class, students will propose a contribution to an open source project and I am looking for mentors.

This is totally empty as of now, but feel free to help organize our Final Projects repo if you are interested in mentoring a student!

Hey hi,

this seems interesting. I would like to contribute. Can we discuss this?

Hey, everyone!

We're always looking for new contributors to Quick. It's a multi-platform, lightweight, easy-to-use framework for 2D game development, focused in performance, fast development and maintainability in JavaScript leveraging HTML5 capabilities.

The main areas I'd like to see some collaboration right now would be the development of new plugins and assets like those listed here.

Of course any kind of collaboration is very welcome, even writing new demos, games and tutorials and then having them listed on the project or shared with the community is very helpful.

Thank you!

Hey Guys,
So we have created this YouTube Downloader in Python. This project initially started as a command line script but later me and my friend turned it into a complete GUI with different features. So we are looking for contributors how would like to help us add more features to this Gui.

  • This uses Python, Pytube Library to fetch and download YouTube Videos.
  • PyQT as a GUI Framework.

Anyone who would like to be part of our project feel free to propose issue and create a pull request.
Btw it also went trending on GitHub.


We could always use a little help with xeogl, which is a WebGL and EC6-based 3D library for visualizing and navigating nerdy things like architecture, CAD models etc.


I reckon we'll have a few first-contributor-friendly tasks going forwards, and ideas, suggestions and PRs are always welcome.

One task task that would be a good starter: adding a minification/uglification step to our gulp-based build process - see this issue.

Would also be nice to add transpilation (eg. using Babel) to EC5. At some point we'll also want to publish the library as a node module.

I'm the creator of this project. I also used to tutoring programming in a university, which I really enjoyed, so we welcome contributions from beginners and gurus alike.

Any contribution is good value, including critique and ideas on where this project should go next. Hit that issue tracker if this one tickles your fancy!


gobacktest is an event-driven backtesting framework written in Golang.

event-driven backtesting framework written in golang

Go Doc Travis Coverage Status Go Report Card Software License

Heads up: This is a framework in development, with only basic functionality.

gobacktest - Fundamental stock analysis backtesting

An event-driven backtesting framework to test stock trading strategies based on fundamental analysis. Preferably this package will be the core of a backend service exposed via a REST API.


Basic example:

package main
import (
func main() {
  // initiate a new backtester
  test := gobacktest.New()
  // define and load symbols
  symbols := []string{"TEST.DE"}
  // create a data provider and load the data into the backtest
  data := &data.BarEventFromCSVFile{FileDir: "../testdata/test/"}

  // choose a strategy
  strategy := strategy.BuyAndHold()

  // create an asset and append it to the strategy

The goal is to create a flexible backtesting system, which could be used as a backend or as a stand alone within a Jupyter notebook.

If you are interested in financial stuff, algorithmic trading or quantitative finance and writing code in Go, feel welcome.

I would appreciate contributors for basic algos, tearsheet and graph integration, documentation or just in general discussion about the structure of the framework from an end user perspective.


I am looking for people to join my project which is an extremely simple Assembly inspired language written in DOTNET/C#, it is designed to teach core concepts and for simple algorithm mockups, shoot me an email at danielshroff@hotmail.com, check it out here or here

I started TesterBot a while back, but I stopped when I learned that Google had released Lighthouse which was quite similar and comprehensive.

However, my vision for this project is far beyond what lighthouse provides. I've also wanted to turn this into a SaaS product while keeping the underlying library open-source and free.

If there's any interest here, I'd like to revive this project. I would love to hear your thoughts!

During development, there isn't enough time to write tests, so our only option is manual testing. We don't need a reminder of how inefficient, time-consuming, error-prone and boring that can get. When we get around to writing test-automations, we spend a lot of time writing tests from scratch. However, most of the test-cases for testing web-applications can be automated and reused.

We created Testerbot to automatically test web-applications during the development process via Puppeteer which talks to Headless Google Chrome.

The basic framework is ready and we have implemented a few test-cases, but we need help in adding more reusable test-cases.

Note: I started this project several months ago and built a SaaS product, but realized that an open-source test automation package will help catch issues quickly during development. I recently stumbled upon frontendchecklist.io/ and created github issues to automate as many of thoseโ€ฆ

Saka is a chrome and firefox extension that allows users to search through open tabs, recently closed tabs, history and bookmarks. I am looking for anyone who wants to help in any aspect of development (adding features, fixing bugs, updating/creating documentation, improving testing and more).

Let me know if you are interested!

Hi everyone,

I'm still working on Pencil.js, a nice Javascript drawing library. The goal is to merge ease of use (OOP syntax and strong default setting) with great flexibility (lots of options and modularity).

Read this post for more in-depth presentation :

I'm mainly looking for feedback from new users, but I'll be glad to work with someone willing to contribute.

See ya.

Hi Guillaume,
Why would I use Pencil.js as opposed to SVGs ?

The SVG syntax is part of the problem that push me to do Pencil.js (along with p5).
I love the OOP syntax, maybe too much, but that's how I think. I want to be able to add a Rectangle instance to a Scene for example.

The SVG path syntaxe is a joke IMO. But it's compatible with Pencil.js Path class.
Shapes are ok, but lack the reactiveness of programmatic Javascript.

Check the examples for more details.

Hi guys! I have a few hours per week free for contribution. Currently I work as full-stack js dev. But I also like (really like) python and want to learn Go or Rust. Or anything. I'm interested in open source projects for the community, health, environment, cutting edge tech to make this a better world. I've been coding for almost 6 years now. So ping me if you need an extremely curious and passionated dev.

Finances are hard. It's one of the first adulting things everyone has to wrestle with. So, let's make it easy and automate it. Over the course of several years, my wife and I have tracked our finances using a forecasting method and had done it all within a spreadsheet. The time came where I wanted to take this concept and make it mobile using serverless architecture and clean design.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Great project. We are working on our build pipeline right now. Anyone with Docker or build skills in general should come over and at the least do an inspection with feedback. Lots of junior devs on this project that would appreciate seniors dropping in even if it's for a quick consult

Interested in working on a project to get me started with back-end development. PHP, Go or maybe Javascript would be fine.

Classic DEV Post from May 11

My Programming Journey: Have Patience And Avoid Burnout.

This week I decided to talk about a couple of things that I feel like probably a lot of you might go through on your way to getting where ever it is you want to get to. And that is that burn out feeling or lack of motivation after the fun of doing something turns into well work. And having the patience to get to your goal.
