Are you ready to ‘Git’ into Open Source

Open Source health information systems provide cost-effective tools for healthcare. Even if you are not a coder, you may be able to contribute to open source projects. As a matter of fact, some open-source projects find it difficult to get volunteers to document and test the code. E-Health enthusiasts from the clinical and management fields often want to contribute to popular open source projects, but do not know how. 

Open source projects involve a collaboration of people with various skills, often with no way of physically meeting each other. In a complex software product, even a misplaced comma can break the system. How do open source projects effectively collaborate avoiding such code-breaking mistakes? Well, they use some specialized tools and workflows to manage code, many of which are not familiar to non-programmers. In the next few posts, I will introduce you to the most important tool that coders use; the versioning system. We shall discuss Git (the most popular versioning system), from a non-programmers perspective.

This is not for those who are familiar with Git and we will not be discussing advanced Git usage. Hence, let me state the assumptions that I am making about you as the reader. You have not heard of Git before. You are as scared of code as you are scared of python. When you hear Java, the first thing that comes to your mind is the island in Indonesia. You don’t know what ‘typing on the command line’ means. But you own a computer, know how to download and install programs, know how to navigate the web, wants to learn more about contributing to open-source projects and above all want to help save lives especially in resource-deprived areas. Watch the video below for inspiration.

At the end of this journey, you will know how to follow open-source projects and make minor code contributions. This might initiate you into learning computer programming, but that is not my intention. You might even win a free T-Shirt from DigitalOcean.

Up and running with activiti in 20 minutes

Activiti is a BPMN automation tool that makes communication between business analyst and the developers easy. Activiti has a web-based graphical interface for business analysts to prepare workflows that can be enhanced by developers adding Java code using an Eclipse plugin. It has a lightweight engine that can be embedded in Java applications to deploy the workflow and an explorer for deploying the process definitions online. Activiti also has a REST interface.

Activiti uses an in-memory database by default. Installation requires Java and servlet container like Tomcat. I have created a puppet script to automate activity installation in a virtual machine. The script installs activity Explorer and the REST interface with the mySQL database. if you want to connect to an external database you can make the necessary changes in the properties file within the code folder.

Installation instructions for Activiti

There are ways of creating a virtual Linux machine in your laptop (Mac and Windows). Virtualization leaves your operating system untouched, and the virtual machine can be removed without a trace after use. Without further ado, you can install this in 5 easy steps using my puppet script.

1. Install VirtualBox.
2. Install Vagrant.
3. Download and extract the zip file below to any folder.

RM1

4. Windows users double-click run.bat. Mac users run the following command from the download folder.
(The script takes approximately 10 minutes to setup the machine. However, no response is needed from your part. An internet connection is required.)
5. Access in your browser:

  • Access Activiti at http://localhost:8001/activiti-explorer
  • Access REST interface at http://localhost:8001/activiti-rest/services

To stop the machine on windows, use stop.bat and on Mac:

You can restart the machine as step 4 above. Restarting the machine does not require an internet connection.

If you want to destroy (uninstall) the virtual machine, use the following command in the script folder.

Feel free to fork and improve this script on GitHub. Pull-requests are welcome. Join E-Health on GitHub if you want direct write access to the repository.
