Happy to have contributors on my beginner-friendly project!

I built a Node/Express/MongoDB app called ValueMax that lets you calculate the cost-per-use of the things you buy.

There are a few open issues in the repo and I'll keep adding more throughout Hacktoberfest. Everything from documentation to new features so hopefully beginner coders can find something to work on.

I'm a relatively new coder myself, so if anyone experienced (or not) wants to take a look through and suggest improvements or even new features, I'd love it—you can add it as a new issue 😄👍👍

MousePaw Media is looking for C++ and Python developers who are interested in working on unusual, cutting-edge libraries, tools, and games.

Current Projects

Here's a look at a few of our current projects:

PawLIB 1.1: High-performance, memory efficient containers and utilities for the C++ language. We're expanding our testing library (Goldilocks), improving and expanding our data structures (Flex), making message output a delight again (IOChannel), and building a tool for streamlining the design of CLI interfaces (Blueshell).

Right now, we're working on iterators for the Flex data structures, adding a new high-performance, doubly-linked list implementation, and building our collection of sorting algorithms.

Omission is a game written in Python 3. It currently uses the Kivy GUI toolkit, but needs to be re-implemented in Qt5 (PySide2).

DiamondQuest is a brand new Python 3 game, which will use the Qt5 (PySide2) GUI toolkit. We're especially needing someone with pixel-art skills to create the retro-style graphics.

Ratscript: A brand new language which seeks to combine an innovative, obvious syntax with a powerful combination of paradigms. Ratscript is being designed specifically for the next generation of game development. Takes cues from Python and Rust, among others.

Anari: A vector-based animation engine implemented in C++, allowing for memory-efficient interactive animations to be deployed onto old and new hardware alike.

Infiltrator is an upcoming Python 3 party game. We have an earlier version implemented in C++, but we want to recreate it in Python3 and Qt5 (PySide2).

Our Stack

  • C++14 (C++17 proposed)
  • Compilers: Clang and GCC
  • CMake
  • Python 3
  • Qt 5/PySide 2
  • CPGF
  • Eigen
  • Git
  • Phabricator

Getting Involved

See something you like? Jump right in! We have a robust development platform, centered around a carefully-honed Phabricator instance.

NOTE: We are currently screening new accounts on Phabricator. We try to approve all new accounts within 24 hours.

For more information, visit or contact developers (at) mousepawmedia (dot) com. You can also ask questions and join the discussion us on the Lobby chatroom on our Phabricator.

I have been dabbling with a side project for writing books. I generally treat is as something I practice on, but if some front end dev would like to hop on and improve the look and feel of it a bit, I would be grateful. Backend devs are welcome too, of course, just let me know in advance, so I can give you a task.

And if you want some legacy project to work on, see c-pChart. It is a wrapper for a statistics library wrote with PHP 4, that I maintain for various folks out there that still use it. It is pretty popular, too.

Hi Ya'll. Ain't nobody got time for testing!


A pet-project of mine that started as a super lightweight & flexible way to add Tags functionality to HTML (since the browser doesn't supports such input type out-of-the-box and with time I've added more and more features and now it's even a React component, but here's where i'm at:

The script has many different options, branching into many different possible scenarios, and every change I make to the code can possibly break one of those possibilities.

I've started writing integration tests (Jest + Puppeteer) but there are a lot of tests that should be written, and this might be a good opportunity for a person who wants to add some integration-testing skills to their CV (or just want to help out of good will)

I believe integration testing is better than unit testing because it can cover them also plus test user-interaction (browser events), which is a crucial part of the script, while also superficially testing the visuals (UI)

I made a repository called XbyY, that aims to be a database of commonly faced problems in software development, some of which can be actually easily solved using a library, framework or a software development methodology.

The problems that we will address are typically of the kind that cannot be easily discovered via a google search, either because it's verbose or a newbie like me might not know what to call it and if a thing like it already exists.

Xs are the problems and Ys are simple yet elegant solutions to it. The Ys could be libraries, frameworks or code snippets (not limited to it though). They may also be design patterns, data structures, etc.

It's an easy/medium PR. You can find the repository here. Thanks for reading! :D

juanfrank77 profile image
Juan F Gonzalez

Question. How broad or specific can the problems be and also the solutions? For instance a common gotcha in React with state and stuff or something like proper architecture in a Spring app.

manjrekarom profile image
Omkar Manjrekar

Yes that can be included. The problems may range from very broad stuff, like exchanging states like you mentioned, or testing, or an architecture and even narrower ones like how to do form validation easily (problems can actually be argued upon to be narrower or broader ones I believe). But solution has to be very specific so that someone who is having that problem actually finds solution helpful and understandable. It should contain resources so that he/she, in most cases will not have to look beyond these resources when practically approaching the problem. You can also include multiple solutions and tutorials links, etc. to those.

C&P from last time:

I want to release a new version of my static blog generator in November or something. Possible tasks that need to be done anyway (however, if I need to do them myself, it'll be years...):

  • Integrate a search functionality via index files, ElasticSearch or something.
  • Split the main file (src/blogcpp.cpp) into more smaller files for easier maintenance. (Optimum: Integrate as much as possible into src/helpers.h without breaking that file's portability.)
  • Integrate libautoupdate for automatic update checks - sometimes I release new versions, you know? :-)
  • If comments are enabled, the supported comment systems offer a way to show how many comments were made under an article. Implement that for each of them.
  • Check if meson could replace CMake easily. If it does, do it.
  • Improve the Markdown parser: it lacks support for underlined headlines and non-standard features like GitHub's tables.

If nobody helps me, the next version will be released without any of those improvements. ;-)

Also, there is still the sufficiently popular ymarks project. It could need more testers. And probably some work on the server part because it is said to crash sometimes - I can't safely reproduce that...

None of those will get you Hacktoberfest credits (because GitHub is entirely uninteresting for me), but I'll like you more if you consider to contribute.

I built a very simplistic honeypot using an esp8266 microcontroller that I programmmed in Micropython. The esp8266 creates a telnet server, and must be port forwarded in order to be accessed by others. When a hacker logs into the server, they get a fake terminal interface, and they have some commands available to them (I tried to make it look like an ancient account processsing terminal from a bank). The original inspiration for this came from the Arduino honeypot found on reddit. This is my first reasonably-sized project, so any suggestions and edits are welcome. Link to the repo here

As always, Orchid is open for contribution. There are several issues with the "hacktoberfect" label perfect for you to jump right in, such as:

Orchid is a new framework for building and publishing static sites, aiming to fix the problem of needing multiple tools to document a single project. Orchid's unique plugin architecture allows you to seamlessly integrate source code documentation (currently supporting Java, Kotlin, and Swift), easily navigable wikis, changelogs, blog posts, and much more, all in a single easy-to-use, well-connected, and SEO optimized tool. And when your site is ready, Orchid can deploy your site directly to Github Pages, even keeping older versions around for historical documentation.

Here are some example sites built with Orchid, so you can see just how much can be done with Orchid and get inspired to help out.

I don't see the similarity except the task board section which is similar for all kanban type boards, other then that I don't find much similarity. All the section are reviewed by several designer in different forums and so far nobody has said anything like that.

Thread Thread
yaireo profile image
Yair Even Or

I am extremely curious about the motivation to spend incredible amount of time developing a tool that looks and does what Trello do for many years.

is the motivation purely business, to try catching a chunk of the same Trello user-base, or is it a try to make yet another task-board app that is believed by its created to be superior to the others already exist in the market.

I'm trying to understand the mindset of a developer starting such a gigantic project, and what does this developer hopes to achieve?

Please answer, if you may, in a way which is emotionally detached way, not to take the discussion to an unproductive path. Thanks

  • Complete the test cases and docs.

  • Complete the Model Hub. (Prototype is at

  • Complete packages for some classic tasks as "Official Repo"

  • Complete third party package upload.

As an open source software, I am really sorry that we cannot promise you anything. But the following is what I can do:

  • We will have an Authors List for all the contributors.

  • There will be logo banner and donors page at the bottom of our Model Hub for sponsors.

Repo: OwaspHeaders.Core
Open Issue: Feature-Policy header is not supported
Language: C#
License: MIT

It's not necessarily a beginners issue, because of how I've structured the project and it requires a little knowledge about how ASP NET Core's HttpContext class, the use of my HttpContextExtensions class, a little knowledge about how the Builder Pattern, and a working knowledge (or ability to switch browser tabs I guess ¯_(ツ)_/¯) of HTTP headers.

The issue itself should have links to all of the documentation required in order to do the work. I can see the work required for this header taking a similar path to the way that I've implemented the Content Security Policy stuff.

A Hyperapp component that implements the Google Invisible reCAPTCHA.



npm install hyperapp-google-invisible-recaptcha --save


The library consists of a component that instantiates an invisible reCAPTCHA and provides some functions for performing validation actions. The component is declared as:

import Recaptcha from 'react-google-invisible-recaptcha'
let recaptcha = null; //Stores a reference to the API functions
  onInstanceCreated={instance => recaptcha = instance}
  sitekey={ <sitekey> }
  onResolved={ () => console.log( 'Ah, I see you are human' ) } />


The component accepts the following props:

  • sitekey: sitekey for your reCAPTCHA. Required.
  • onResolved: callback function when the reCAPTCHA is resolved. Required.

Optional props that you can add to tweak the component.

  • locale: the language of the reCAPTCHA. Default: en.
  • badge: bottomright, bottomleft, or inline. Where the visual…

Simple Fetch interface http decorator wrapper for your functions.

HTTP Fetch Decorator

Simple Fetch interface decorator wrapper for your functions.

$ npm install http-fetch-decorator


Then you can place the decorator which has the same input structure as the fetch function. The parameters of the request or the data to send as a body are passed via arguments to the wrapped function, and the result and error objects are available as parameters of the function as well:

@Fetch(Url: String, initObj?: Object)
static wrappedFunction(params: Object, result? : Response, err? : any){

How to use it

import Fetch from "http-fetch-decorator"
class AnyES6Class {
  @Fetch("apiexample/getsomething", {method: 'GET',mode:'cors'})
  static parseResponse({id: '1'},result,err) {
    if(err) throw err
    //Result contains the Response
