Obviously, it is worth sharing not only your success stories but also your failures in order to anticipate the future better.
During the fucked up session, I had a presentation describing a story where the problem arose over time, and whether the fan would scatter the waste was not a question of if but when.
Crackers literally had attacked a website, and as it turned out, no one had a safe copy, and only defaced backups were available.
DevOps often say that we divide people into those who make backups and those who will make backups.
From the summary of my presentation, it seems worth adding another group of people – those who check whether restoring a backup is successful.

Let me share my latest #AMP Accelerated Mobile Pages #WordPress presentation held at WordUp #Trójmiasto meetup.

Just a recap of the main thoughts about AMP:

#AMPHTML

AMP HTML is HTML with some restrictions for reliable performance.

#AMPJS

The AMP JS library ensures the fast rendering of AMP HTML pages.

#AMPCache

The Google AMP Cache can be used to serve cached AMP HTML pages.

Allow only asynchronous scripts

Don’t let extension mechanisms block rendering

Minimize style recalculations

Only run GPU-accelerated animations (position, scale, rotation, opacity)

All #CSS must be inline and size-bound 50KB

Keep all third-party JS out of the critical path (except in amp-iframe )

Font triggering must be efficient

We can prioritise resource loading

No !importants

Enjoy!

When you need to add  <body class=”parent-SLUGNAME”> class please add the following code to your functions.php file:

`

add_filter(‘body_class’,’body_class_section’);

function body_class_section($classes) {
global $wpdb, $post;
if (is_page()) {
if ($post->post_parent) {
$parent = end(get_post_ancestors($current_page_id));
} else {
$parent = $post->ID;
}
$post_data = get_post($parent, ARRAY_A);
$classes[] = ‘parent-‘ . $post_data[‘post_name’];
}
return $classes;
}

`
