Programmatically get file URL from a media entity reference field in Drupal 8

I have a content type with a media (image) entity reference field (field_thumbnail_image) and I want to grab its file URL. For this, I need to load the media entity, isolate its source object using getSource, then load this source as a file entity so I can make a proper URL.

    // load the media entity from the media entity reference field
    $media_entity = Media::load($entity->field_thumbnail_image->target_id);

    // get the file source value for the media entity
 $source_value = $media_entity-&gt;getSource()-&gt;getSourceFieldValue($media_entity);

Overview of Python Virtual Environments

This guide is targetted at intermediate or expert users who want low-level control over their Python environments.

When you're working on multiple coding projects, you might want a couple different version of Python and/or modules installed. This helps keep each workflow in its own sandbox instead of trying to juggle multiple projects (each with different dependencies) on your system's version of Python. The guide here covers one way to handle multiple Python versions and Python environments on your own (i.e., without a package manager like conda). See the Using the workflow section to view the end result.

Create a webpack.mix.js file in root directory:

const { mix } = require('laravel-mix');

mix.js('resources/assets/js/app.js', 'public/js')
  .sass('resources/assets/sass/app.scss', 'public/css');
  
/* Optional: uncomment for bootstrap fonts */
// mix.copy('node_modules/bootstrap-sass/assets/fonts/bootstrap/','public/fonts/bootstrap');

use Drupal\field\Entity\FieldStorageConfig;
use Drupal\field\Entity\FieldConfig;

$bundles = ['user'];

$fields['user_picture'] = [
  'type' => 'image',
  'entity_type' => 'user',
  'bundle' => 'user',

Docker - How to cleanup (unused) resources
