Other communication¶

GitHub is a fantastic platform for collaborating on open source software, but it can’t do everything. Additionally, we work with other people or institutions that use different platforms for collaboration, teamwork, and communication. While Xdev uses GitHub for as much as we can, we acknowledge that sometimes you have to use something other than GitHub from time to time.


Email should be used sparingly, but there are times when it is necessary. Sending invitations to Zoom or Google Meet calls sometimes requires knowing a teammate’s individual email address, which results in an email notification of the newly scheduled event. Email is also a convenient mechanism for people outside of the team to communicate with us, in which case responses over email are obviously appropriate.

Communication directly between team members with email should be discouraged, though. The only time when such communication is appropriate is when you need to reference another email (e.g., replying or forwarding) for discussion, or you need to reference a Zoom or Google Meet event for which you were notified via email.

These rules apply for both your individual work email addresses and the Xdev Team email address (xdev@ucar.edu).


Zulip is an open source chat platform for distributed teams. Because it is open source, we were able to launch our own Zulip server on NCAR systems. We launched this platform primarily as a means for scientists to collaborate with the Xdev Team and each other around issues related to the adoption of Python and the Pangeo stack.

Zulip is primarily useful for replying to people who are outside the team who have questions that the team can answer about Python, the Pangeo software stack, and general application questions regarding analysis. The Team should monitor Zulip on a semi-regular basis, once or twice a day. Fortunately, traffic on Zulip is not so great as to require more than that, even for a team our size!

Zulip can also be useful for one-on-one communication between teammates. Use Zulip for this rather than email, as much as possible. Also, use Zulip for direct communication with another person primarily as a means of keeping other communication channels “less noisy,” even if the communication specifically doesn’t have anything terribly private in it.

Zulip Best Practices¶

  • Be timely in responding to people on Zulip. One of Zulip’s greatest benefits is as a “quick” communication platform. You shouldn’t expect people to respond to you (or for you to respond) immediately, but a person should expect getting a response within the day.

  • When a person creates a topic for a specific question, and the answer to the question reveals that the topic title doesn’t really communicate the actual problem the person was experiencing, then it is useful to rename the topic.

  • When a particular question seems like a common stumbling block, or a recurring question, or is just particularly challenging for a person to figure out on their own, it can be useful to post that question and answer in the ESDS FAQ.

Zoom & Google Meet¶

We use Zoom and Google Meet for many of our meetings. These video meeting platforms are great for direct, synchronous communication. But to accommodate everyone’s busy schedule, we use these platforms only when synchronous communication is necesary.


Blog posts are an excellent forum for telling people about what we are doing and for sharing our little successes. Everyone in Xdev is encouraged to write a blog post for the ESDS Blog on a monthly basis.
