The really big list of really interesting Open Source projects.
--
Hi, dear developers and readers!
If you are interested in Open Source and are considering joining the community of Open Source developers, it is possible that in this list you will find the project that will suit you (In fact I am sure that you will find).
Here are you can see the really big list of really interesting Open Source projects on languages such as Elixir, Erlang, Haskell, Clojure, Python, Ruby, Lua, JS, Go, C++, Swift, Bash, R and etc.
I have a blog where I write about software development and stuff, so feel free to subscribe me: https://isaak.dev/
I have a Telegram channel where I cross-post articles from my blog and post all the open-source goodies I found: @the_art_of_development.

Magit is an interface to the version control system Git, implemented as an Emacs package. Magit aspires to be a complete Git porcelain. While we cannot (yet) claim that Magit wraps and improves upon each and every Git command, it is complete enough to allow even experienced Git users to perform almost all of their daily version control tasks directly from within Emacs. While many fine Git clients exist, only Magit and Git itself deserve to be called porcelains. (more)
Clack is a web application environment for Common Lisp inspired by Python’s WSGI and Ruby’s Rack.

tensorflow — an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) that flow between them. This flexible architecture lets you deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device without rewriting code. TensorFlow also includes TensorBoard, a data visualization toolkit.
Magenta is a research project exploring the role of machine learning in the process of creating art and music.

body="Find the best daily deals") response = requests.get('http://yipit.com') assert response.text == "Find the best daily deals" httpretty.disable() # disable afterwards, so that you will have no problems in code that uses that socket module
httpretty.reset() # reset HTTPretty state (clean up registered urls and request history)
falcon — is a high-performance Python framework for building cloud APIs. It encourages the REST architectural style, and tries to do as little as possible while remaining highly effective.
Example:

# Falcon follows the REST architectural style, meaning (among
# other things) that you think in terms of resources and state
# transitions, which map to HTTP verbs.
class ThingsResource(object):
def on_get(self, req, resp):
"""Handles GET requests"""
resp.status = falcon.HTTP_200 # This is the default status
resp.body = ('\nTwo things awe me most, the starry sky '
'above me and the moral law within me.\n'
'\n'
' ~ Immanuel Kant\n\n')# falcon.API instances are callable WSGI apps
app = falcon.API()# Resources are represented by long-lived class instances
things = ThingsResource()# things will handle all requests to the '/things' URL path
app.add_route('/things', things)

Mimesis is a fast and easier to use Python library for generate dummy data. These data are very useful when you need to bootstrap the database in the testing phase of your software. A great example of how you can use the library is a web applications on Flask or Django which need a data, such as users (email, username, name, surname etc.), posts (tags, text, title, publishing date and etc.) asf. The library use the JSON files as a datastore and doesn’t have any dependencies. The library offers more than 22 different data providers (from the personal to transport and not only).
Below you can see, how to generate fake paths using Mimesis:
>>> import mimesis
>>> person = mimesis.Personal(locale='en')
>>> person.full_name(gender='female')
'Antonetta Garrison'
>>> person.occupation()
'Backend Developer'
>>> templates = ['U_d', 'U-d', 'l_d', 'l-d']
>>> for template in templates:
... person.username(template=template)

print('match')
else:
print('not match')# Output: 'not match'
also you can use compiled patterns:
from expynent.compiled import usernameu = input('Enter username: ')if username.match(u):
print('valid')
else:
print('invalid')

distillery — a pure Elixir implementation of release packaging functionality for the Erlang VM (BEAM).
Every alchemist requires good tools, and one of the greatest tools in the alchemist’s disposal is the distillery. The purpose of the distillery is to take something and break it down to it’s component parts, reassembling it into something better, more powerful. That is exactly what this project does — it takes your Mix project and produces an Erlang/OTP release, a distilled form of your raw application’s components; a single package which can be deployed anywhere, independently of an Erlang/Elixir installation. No dependencies, no hassle.
This is a pure-Elixir, dependency-free implementation of release generation for Elixir projects. It is currently a standalone package, but may be integrated into Mix at some point in the future.

%HTTPotion.ErrorResponse{message: "econnrefused"}# You can also raise `HTTPError` with the `bang` version of request
iex> HTTPotion.get! "http://localhost:1"
** (HTTPotion.HTTPError) econnrefused

does not compromise speed and maintainability (seems that’s true).
Sugar is a modular web framework for Elixir.
Goals:
- Speed. Sugar shouldn’t be slow and neither should your project.
- Ease. Sugar should be simple because simple is easy to learn, use and maintain.
- Effective. Sugar should aid development. You have better things to which to devote your time.
Example:
defmodule Router do
use Sugar.Router
get "/", Hello, :index
get "/pages/:id", Hello, :show
post "/pages", Hello, :create
put "/pages/:id" when id == 1, Hello, :show
end

{
public Module()
{
Get("/greet/{name}", x => {
return string.Concat("Hello ", x.name);

Dokku is an docker powered mini-Heroku. The smallest PaaS implementation you’ve ever seen.
git-secret — a bash tool to store your private data inside a git repo. How’s that? Basically, it just encrypts, using gpg, the tracked files with the public keys of all the users that you trust. So everyone of them can decrypt these files using only their personal secret key. Why deal with all this private-public keys stuff? Well, to make it easier for everyone to manage access rights. There are no passwords that change. When someone is out - just delete his public key, re-encrypt the files, and he won’t be able to decrypt secrets anymore.

algebird — an abstract algebra for Scala. This code is targeted at building aggregation systems (via Scalding or Apache Storm). It was originally developed as part of Scalding’s Matrix API, where Matrices had values which are elements of Monoids, Groups, or Rings. Subsequently, it was clear that the code had broader application within Scalding and on other projects within Twitter.
Example:
Welcome to Scala version 2.10.5 (Java HotSpot(TM) 64-Bit Server VM, Java 1.7.0_40).
Type in expressions to have them evaluated.
Type :help for more information.scala> import com.twitter.algebird._
