Learn all the do's and don'ts of keeping your experiment server secure to maximize your experiment time!

This month, we announce the early user period for our "edgy" users out there, remind you to please update your list of publications using Chameleon(!) and also let you know of a few important and cool things going on. Stay tuned next month for some announcements about new hardware installations, if all goes well!

Organizing a summer school, bootcamp or workshop this summer? Having trouble finding a consistent and predictable environment? Learn all about how to use the Chameleon JupyterHub artifact to configure resources (including GPUs!) and create a shared Jupyter notebook computing environment that any event attendee can use. You can manage users, deploy Chameleon resources, and use the Help Desk throughout your event!

The summer is almost in full swing, and we're frantically getting stuff done so we can kick back and just rest on our laurels from May until August… just kidding. Expect lots more fun stuff to be announced this summer! For now, enjoy your latest changelog.

 

In this issue, learn more about running a workshop on Chameleon, blocking out portions of time on your CHI-in-a-Box associate site to "set it aside" for other uses, try out a new Jupyter tutorial around stitching, and apply to take ownership of some of our legacy hardware! We're also very excited to get some …

Explore CHI-in-a-Box with the new QuickStart notebook, which guides you through the process of setting up CHI-in-a-Box on a bare metal CentOS 8 machine. Announcing a preview of Bring Your Own Device, a feature that allows operators to enroll and manage Chameleon hardware with greater ease. Easier CLI authentication from within your bare metal instances. Add users to your project by either username or email address. And, enjoy a new release of the Jupyter interface!

Chances are, if you're using Chameleon today, you're probably utilizing either the GUI or the CLI (or a mixture of both.) Did you know there's a Python library that makes it easy to script your Chameleon experiments? In January we announced the public release of python-chi, the official Python library for CHI (Chameleon Infrastructure), which is exactly that. Read on to learn all about python-chi and how to easily use it to experiment on Chameleon.

Winter's almost over! This month we have a lot of announcements, notably a big facelift for CHI-in-the-Box, the packaging of Chameleon, but also a new interactive handbook for Chameleon and some nice KVM capabilities.

Hey! It's your friendly neighborhood Chameleon changelog, back from a long vacation. This month we announce general availability for CHI@NU, new Cascade Lake racks at CHI@TACC, and more!

We'd like to take a brief moment to reflect with gratitude on what went right this year, at least in the (small) realm of our work on this research testbed. So here’s one year in review, representing combined “changelog” information from the entire year.

Trovi is the next iteration of the Chameleon experiment management and sharing platform. With Trovi, you can set up and configure your experimental environment from within a Jupyter notebook, document and save your experiment similarly in notebook form, and privately share it with collaborators or publish it for any Chameleon user to build on.
