Dallinger
~~~~~~~~~

Dallinger is a tool to automate experiments that use combinations of automated bots and human subjects recruited on platforms like Mechanical Turk and Prolific.

Dallinger allows crowd sourced experiments to be abstracted into single function calls that can be inserted into higher-order algorithms. It fully automates the process of recruiting participants, obtaining informed consent, arranging participants into a network, running the experiment, coordinating communication, recording and managing the data, and paying the participants.

The Dallinger technology stack consists of: Python, Redis, Web Sockets, Heroku, AWS, Mechanical Turk, Prolific, boto, Flask, PostgreSQL, SQLAlchemy, Gunicorn, Pytest and gevent among others.

    Dallinger is *open-source*, and is *completely free* to use in your experiments. However, to help users with technical issues and experiment creation, the Dallinger team maintains a **Dallinger support Slack channel**. Access to the Dallinger support Slack requires a **$10 per month per user subscription**, with proceeds supporting the future development of Dallinger. Users are free to subscribe for as many or as few months as they wish.

    To subscribe and gain access to the Slack support channel, please `download <_static/download/IHO_Dallinger_invoice_TM__1_.docx>`__ and complete this invoice. Completed invoices, along with a check for the appropriate amount, should be sent to the address on the invoice. Upon the invoice being processed, the listed users will be added to the Slack channel. If you are from a developing nation and are unable to afford a subscription, please contact us directly.

User Documentation
^^^^^^^^^^^^^^^^^^

These documentation topics are intended to assist people who are attempting
to launch experiments and analyse their data. They cover the basics of installing
and setting up Dallinger, as well as use of the command line tools.

Beginner Documentation
^^^^^^^^^^^^^^^^^^^^^^

Many Dallinger users may not have lots of programming experience, and might
want a bit more information about the inner workings of Dallinger in a
beginner-friendly format. Thomas Morgan has started such a project:
"Dallinger for Programming Novices". Every Dallinger user is encouraged to take a look at this guide, which is a
nice complement to the documentation presented here.

These documentation topics build on the previous set to include help with
designing new experiments for others to use.

Alternative Environments Documentation
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

We are currently experimenting with several other development and deployment environments
for Dallinger, such as Docker and Vagrant. These potentially offer various advantages,
such as better cross-platform compatibility, enhanced reproducibility, and so on.
The following documentation topics describe some of these approaches. However,
this work is still experimental and so the documentation is not complete yet.

Core Contribution Documentation
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This section covers extra topics relevant to those wishing to contribute to the development of Dallinger itself. This is not needed
in order to develop new experiments. Follow the Developer Installation process from the previous section to get started.
