Module development and code questions

Hi Guys

I have a views entity reference field that will only be displayed on the node edit form and I want to add an argument to it dynamically to restrict the returned results based on my argument.

Hi there,

This module appears not to be updating ical feeds on every cron run... but it was working in the past. 

I have set up cron to run every hour. The feed imports the calendar events to a content type.

I have Drupal 8 and Flag module.

I created a flag on the user. How to flag the user's account page when I visit it ?

We were having issues implementing lazy-loading on our D7 website. After a few failed attempts we discovered another method that we were able to implement. 

In real world testing it appears to our eyes to defer the image loading. However, Google's PageSpeed Insights does not credit us with having deferred images. Here is a run test: (I had to remove the link in order to pass the SPAM filter)

Here is the img src we implemented (we altered the original white pixel and turned it gray b/c it helped us spot images in our TinyMCE editor rather than look at blanks):
