What is a kernel?

The kernel lets you run code in a particular programming language using one of the Jupyter tools, such as the Notebook, Jupyterlab or nteract. Installing additional kernels will let you run code in more languages using your existing jupyter installation.

Technically, the kernel is an application which speaks the Jupyter Messaging Protocol, to receive code input from the frontend and respond with the results.

Which kernels do I have installed?

In the Notebook or JupyterLab, the list of available kernels will be shown when trying to create a new notebook.

Multiple Tenancy (with separate database) Migration Management for Laravel 5.*

Problem

The existing system used migration mechanism to handle all of the database schema version handling using console command php artisan migrate. By default this migration mechanism allow version for single database. Which is not appropriate when you are dealing with multi-tenancy with separate database application, you might need to handle migration for all available tenants/customers available in your system, and you might also need a master database with separate migration and schema. Thats why, we need to modify default migration mechanism by overriding the migration console commands.

Solution

Laravel ship by default with couple of available useful commands which might help to utilize such mechanism, Following of the option can use for such problem:
