We've learned that our member communities care a *lot* about cloud cost transparency and reliability, so we're working hard to drill down into user data about costs and usage for community leaders to access.

2i2c @2i2c.org · 1d

We're giving our communities more transparency into their cloud expenses with new cloud cost dashboards! Communities can track spending at a per-user level to understand who is driving their usage and take action.

Enabling transparent cloud cost monitoring with user-level dashboards | 2i2c

We are excited to announce that dashboards to monitor cloud usage and costs at a per-user level are now available! A key goal of 2i2c is to make the cloud safe for science.

JupyterLab 4.4.0b1 and Notebook 7.4.0b1 are available for testing 🎉
- improved code console
- settings import/export
- better real time collaboration
- workspace indicator
- kernel subshells

Please test:

pip install --pre 'jupyterlab>=4.4.0b1'

or

pip install --pre 'notebook>=7.4.0b1'

The option to change console prompt position is available under the three dots button in the console toolbar, which is the last toolbar button

Toggling all the three new settings transforms the console into a single cell

The Import and Export buttons in the Settings Editor are the first two items in the toolbar panel

The PR improving the JupyterLab code consoles has been merged, and is now available in the latest JupyterLab, Notebook and JupyterLite pre-releases!

I don't know. I know you can install new versions of JupyterLab in environments and use them in JupyterLab Desktop even if JupyterLab Desktop comes with an old one bundled (this is how I use it). I will try to raise this issue in the Jupyter community.

RTC: prefix has been a roadblock in wider adoption of #jupyter collaboration as many extensions did not support it. The RTC prefix is no more thanks to content providers pioneered by @davidbrochart.bsky.social 🎉

I 100% agree and tried to push back repeatedly against such proposals. Thank you for your comment. In a similar vein I also saw a proposal to only commit visual regression snapshots from macos which I see as discriminatory in the same way. I hope @projectjupyter.bsky.social does not go this way.
