Teaching C++ programming to non-computer science majors comes with the
burden of setting up an integrated development environment, a struggle
for most students. Therefore, we present the open source tool,
*C++Explorer*, a Jupyterhub deployment for interactively developing C++
code. Students can connect to the server without installing anything,
and, almost instantly, they can begin to play with code using the
notebooks. Another aspect of code development is remote communication
with co-workers or the community. To develop this skill, we use GitHub
classroom to provide feedback on the assignments and practice remote
communication. *C++Explorer* was used in the fall of 2019 to teach
parallel computation to mathematics students. At the end of the class,
these students provided feedback through a survey. This data will be
used to improve the next iteration of the course.
