These are the companies or individuals contributing a monthly amount to help sustain EinD development. See the bountysource campaign for more details.
Bountysource does not yet provide a UI for sponsors to inform their URL. Most URLs displayed in the list were obtained using the github API and a heuristic to match the bountysource slug(a sort of sponsor identifier) with the github username, but this method was error prone and failed for many sponsors, including those that don't have a github account.
If you are pledging $5/month or more and want to have your URL listed, please send a PR to EinD.github.io with a new entry for your bountysource slug in the js/sponsors-override.js file. You can obtain your bountysource slug with the following command:
curl --header 'Accept: application/vnd.bountysource+json; version=2' 'https://api.bountysource.com/supporters?team_slug=EinD&per_page=10000&page=1' 2> /dev/null | python -m json.tool | grep -C5 $NAME | grep slugwhere $NAME should be replaced by your bountysource display name(as shown in the sponsor list).
To fulfill the $250/month rewards for the new campaign, they were moved to a separate page.

I have some experience on almost every field of development. I do develop things for backend and frontend, but also I do have an article about deep learning and I do have some data science background. While I am working with Python, .Net, and JS, I am keen to be a Gopher in future.
I do have some experience with Azure and I am trying to learn more about topics like DevOps, Deployment pipelines, Serverless and Docker. I do use GNU/Linux distros for 5+ years which makes easier to learn them. I am practising those topics on my current company.
I like participating in hackathons, writing professional articles, listening to technical podcasts, sharing my knowledge, and discussing diverse topics. I am always trying to learn more from people around me. I work well in a team but also on my own as I like to set myself goals which I will achieve. I do use English regularly.

NEW DELHI: India has been clubbed along with defending champions Argentina and world number one side Australia in Pool A of the 2020 Tokyo Olympics men's hockey competition.
The other teams in India's pool are Spain, New Zealand and hosts Japan. The Pool B is made up of Belgium, Netherlands, Germany, Great Britain, Canada and South Africa in the groupings announced by world governing body FIH on Saturday.
India, ranked fifth in the world, had qualified for the Tokyo Olympics after beating Russia 11-3 on aggregate in the qualifiers held in Bhubaneswar earlier this month.
The women's team has also been placed in Pool A along with defending champions Great Britain and world number one side the Netherlands. The other teams in Pool A are Germany, Ireland and South Africa.
The Pool B is made up of Australia, Argentina, New Zealand, Spain, China and hosts Japan.
Ranked ninth in the world, the Indian women's team had qualified for the Tokyo Olympics after beating United Sates 6-5 on aggregate in the qualifiers held in Bhubaneswar earlier this month.
"To determine the composition of the pools, the same process has been applied as for the Olympic Games Rio 2016. With all participating teams being ranked among the top 16 teams of the current FIH World Rankings, fans can expect thrilling hockey encounters in Tokyo next year," the FIH said in a release.
The 2020 Tokyo Olympic hockey tournaments will be staged in the brand-new Oi Hockey Stadium from July 25 to August 7. The match schedule will be announced later.

Although only 5 NM form St Tropez, this is a very distinctive town. Known as a 'poor man's Venice', it was built only 40 year ago and is based around artificial islands and canals, with the aim of every resident being able to park their boat at the bottom on the garden.
Location 43°16'N, 006°38'E.
There are plenty of guest berths in Port Grimaud and the port is administered by 3 Capitaineries. The office of PG 1 is to sta’bd, just inside the entrance.
This map of the port layout is a useful guide (use the Harbour
tab).
Port Grimaud has two main squares and plenty of shops and restaurants, as well as a weekly market. All facilities are available; yacht chandlers, a post office and even a cathedral.

AllenNLP is a toolkit for doing NLP research. It is built on top of pytorch. See allennlp.org for more information.
The path ranking algorithm (PRA) and subgraph feature extraction (SFE) are algorithms that extract feature matrices from graphs. This git repository contains code implementating these two algorithms, produces matrices that are useful in a variety of situations. The repository also contains code for running experiments doing link prediction in a graph using these feature matrices (also known as knowledge base completion, when the graph corresponds to a knowledge base such as Freebase or NELL).
Using feature matrices generated from graphs (using the PRA/SFE code linked above) to answer questions, both science questions and machine-generated questions from the Facebook bAbI dataset.


Introduction
Before introductiong Simone into your project, check if your using a supported versions of jQuery and jQuery UI, or download the appropriate versions. Also make sure that all the browsers version you need to support are supported by Simone.
Supported browsers
Only modern browsers are supported by Simone. No support for legacy browsers, sorry.
Certain API's, like fullscreen API, are missing in older browsers. Graceful degradation if provided.
| Chrome | Firefox | Internet Explorer | Safari | Opera |
| 17+ | 12+ | 9+ | 6.1+ | 15+ |
Dependencies
Simone require jQuery and jQuery UI. The tables bellow show all compatible versions of jQuery and jQuery UI.
| Compatible jQuery versions | |||||
| 1.x | 1.7.x and bellow | 1.8.3 | 1.9.1 | 1.10.2 | 1.11.1 |
| 2.x | 2.0.3 | 2.1.1 | |||
|
* Other minor jQuery versions from 1.8.0 are likely to work too, although Simone is not tested against them. |
| Compatible jQuery UI versions | |||||
| 1.9.x and bellow | |||||
| 1.10.x | 1.10.0 | 1.10.1 | 1.10.2 | 1.10.3 | 1.10.4 |
| 1.11.x | 1.11.0 | 1.11.1 |
- – supported
- – not supported
- – pending
Required jQuery UI components
Table bellows shows those jQuery UI components that are required for Simone to work, and those that are optional.  Without highly recommended and recommended components, certain features will be not available, but widgets should work (and if they doesn't, please fill a bug report).
Note: When downloading themes from jQuery UI download site, check all the JS dependencies required for Simone, otherwise you will be missing some CSS. Unchecking all the JS files and going only for a particular theme won't work.
Adding files to your project
Adding Simone to your project is pretty straightforward.
First, download Simone version of your choice, either development (uncompressed) or production (compressed) JavaScript and CSS files, and translations for at least one language.
Remember to download compatibile versions of jQuery and jQuery UI.
When you have your files downloaded, unpack or move them to a common directory. For the sake of this instruction, let's assume that simone
is a directory where your Simone files are, jQuery is in jquery
directory, and jQuery UI is in jquery-ui
directory. Let's assume that development versions are used. Assuming that you use js/
directory for all JS libraries, the inside of your head tag should look something like that:
<!DOCTYPE html>
<html>
<head>
<!-- first, include jQuery -->
<script src="/js/jquery/jquery.js"></script>
<!-- second, jQuery UI Theme and jQuery UI itself is needed -->
<link href="/js/jquery-ui/themes/sunny/jquery-ui.css" rel="stylesheet">
<script src="js/jquery-ui/jquery-ui.js"></script>
<!-- it's also recommended to include jQuery UI Datepicker language files -->
<script src="/js/jquery-ui/i18n/jquery.ui.datepicker-all.js"></script>
<!-- now, include Simone -->
<link href="/js/simone/simone.css" rel="stylesheet">
<script src="/js/simone/simone.js"></script>
<!-- include translations after widgets has been included -->
<script src="/js/simone/i18n/simone.all.js"></script>
<!-- other scripts go here -->
<!-- when all libraries are included, start writing your code;
just don't use inline JavaScript - write it in separate file(s)! -->
<script>
$( document ).ready( function () {
// your code goes here—Simone need to be run on
// document's ready event, or after it
});
</script>
</head>
<body>
</html>
Gettings started
There are a lot of demos to get you started with Simone.


It will be applied to your final bill.
