Welcome to the February 2023 OpenScienceLab Update!

Changes:¶

• OpenScienceLab
• Single Sign On
• Automatic Authentication
• User Access
• IP Filter
• User Request
• Multi Download
• Kernel Usage
• Recommended Jupyter Notebook Changes

OpenScienceLab¶

• OpenSARLab is now a part of OpenScienceLab with significant changes. Users can access different courses from a single page.

Single Sign On¶

• New single sign-on (SSO) to simplify the logging-in process. SSO eliminates the burden of the sign-on process by listing all accounts on a single web page with additional layers of security.

Automatic Authentication¶

• Users who sign up to the OpenScienceLab no longer need admins to activate their accounts.

User Access¶

• Admins can easily give users access to different profiles from a single page. Admins can toggle access lists based on various deployments.

IP Filter¶

• OpenScienceLab will prevent users in one of NASA’s designated countries list from creating an account so that we are compliant with NASA’s security protocol.

User Request¶

• Users can send a request to the OpenScienceLab team from the portal.

Multi Download¶

• Users can download multiple files at once through OpenScienceLab.
• NB: Downloading multiple directories requires users to compress the directories beforehand.

Kernel Usage¶

• The latest update of JupyterLab has a built-in kernel monitor that tracks detailed resource usage, such as:
  • Kernel Host
  • Memory consumption and availability
  • CPU usage

Recommended Jupyter Notebook Changes¶

The following bullet points cover code changes you may need to make to your notebooks for them to work in JupyterLab:

• MintPy Update:

  Due to the recent MintPy update, import syntax for version 1.4.1+ differs from previous versions. As a result, some notebooks may be incompatible with the latest version of MintPy. Below are examples of how to import MintPy depending on which versions you have:

  # version 1.4.0 and below:
  import mintpy.view as view
  import mintpy.tsview as tsview
  .
  .
  .
  
  # version 1.4.1+
  from mintpy.cli import view, tsview, ...        

For additional backward compatibility changes, please refer to the previous release notes.
