Open Source

2i2c are pleased to announce the development and deployment of automated backups of home directories on GCP-hosted hubs! We have developed the gcp-filestore-backups project that regularly creates backups of JupyterHub home directories for disaster recovery purposes.

This quarterly post is coming out a little bit late - our goal was to post this in early January, but the year has been more complicated than we bargained for :-)

When sharing a storage disk between users, as is usually the case in a JupyterHub deployment, it is important to put in guardrails so that one user cannot eat up the whole storage capacity from the rest of the users.

A key challenge in the open source space is that projects are often independent and autonomous, with relatively few formal ways to collaborate and coordinate efforts. While this usually isn’t a big deal, it means that there is a missed opportunity to grow the impact of an ecosystem because it requires coordinated development among multiple stakeholders within it.

In this post, we’re sharing our Commitment to Open Technology. It is focused on software licenses for reasons we’ll describe below. We hope that it clarifies what kind of licenses we’ll use, and assures our communities that we will not change our stance towards open source technology in the future.

A non-exhaustive list of things 2i2c and Development Seed did with the NASA VEDA project last quarter! Automated backups and alerting with jupyterhub-home-nfs # Tracking Issue jupyterhub-home-nfs is a young project to provide flexible per-user home directory limits on JupyterHub - an important feature for controlling cloud costs.

2i2c is pleased to announce the frx-challenges project, a new open source tool to help communities host data challenges on shared infrastructure: 2i2c-org/frx-challenges This project aims to make it easier for administrators to provide a service that enables users to submit code and data that are evaluated on secure infrastructure with access to private data and resources.

On most research oriented JupyterHub installations, users would like to customize their server (the environment, resources available, etc) after logging in. In Kubernetes based JupyterHub environments, a profile list provides this functionality.

Cross-posted from the Jupyter Book blog. Note that some MyST functionality is not supported on the 2i2c website – please see the original post for previews. Over the last ten months, the Jupyter Book team have been hard at work; Jupyter Book has become a Jupyter subproject, and the team1 announced a plan to release Jupyter Book 2.
