Drupal Bartik Admin-Super admin theme forever.

It's just an emerging product. As a bartik, we have to always configure the superadmin. The software settings may be overridden if you need to. It will only be open to the superadmin useruid 1.

The admin pages will be overridden by super admin theme as batrik. Drupal lets you identify a specific Admin Pages theme.

Drupal 8 uses libraries theme.libraries.yml

 globle-styling:
   version: VERSION
   css:
     theme:
       css/style.css: {}
 style-engb:
    version: VERSION
    css:
      theme:
         css/style-gb.css: {}

All Admin pages are in English and admin menu always in LTR?

1) First go to Administration -> Configuration -> Regional and language -> Languages -> Detection and selection tab and make sure to have “Account administration pages“ enabled.

2) Then go to People and edit your user. Admin -> Edit Profile -> Edit

Go down to the Language settings section. You should now see a Administration pages language dropdown. 

Select and save.

3) Go to the administration language using the following settings:

url: /admin/config/regional/language/detection

"Account administration pages" - Enabled

"Follow the user's language preference." - Enable

and drag and drop to the top position.

Install a XAMPP on your local machine.  Followed recommendations to not install in program files as there is some firewall problems. (e.g., c:\xampp)

There are a couple of solutions to change the page title

/**
 * Implements THEME_preprocess_page_title()
 */
function THEMENAME_preprocess_page_title(&$variables) {
  $current_url = \Drupal\Core\Url::fromRoute('<current>');
  $url = $current_url->getInternalPath();
  if($url == 'home') {  
    $variables['title'] = 'Welcome to Development Portal | ThirstySix';
  }
}

/** 
 * Implements THEME_preprocess_page(). 
 */
function THEMENAME_preprocess_page(&$variables) {
  $node = \Drupal::routeMatch()->getParameter('node');
  if ($node) {
    $variables['title'] = $node->getTitle();
  }
}

Create a 301 redirect for all http requests that are going to the old domain to new domain

If you are wanting to only redirect a specific subdomain, you would do something like this:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^olddomainname.com$ [OR]
  RewriteCond %{HTTP_HOST} ^www.olddomainname.com$
  RewriteRule (.*)$ http://www.newdomainname.com/$1 [R=301,L]
</IfModule>

[or]
  
Redirect  301 /olddomainname http://www.newdomainname.com

Theme hook enables any module or theme to provide suggestions for alternative theme feature or template name suggestions and reorder or remove suggestions.

Drupal 7:

<?php
/**
* Implements hook_preprocess_HOOK() for node templates.
*/
function MYTHEME_preprocess_node(&$variables) {
  $variables['theme_hook_suggestions'][] = 'node__' . 'first';
  $variables['theme_hook_suggestions'][] = 'node__' . 'second';
}

Drupal 8:

<?php
/**
* Implements hook_theme_suggestions_HOOK_alter() for node templates.
*/
function MYTHEME_theme_suggestions_node_alter(array &$suggestions, array $variables) {
  $suggestions[] = 'node__' . 'first';
  $suggestions[] = 'node__' . 'second';
}

function "do_gettimefoday" is used to get the time value in kernel.

struct timeval time;

unsigned long local_time;

do_gettimeofday(&time); local_time = (u32)(time.tv_sec - (sys_tz.tz_minuteswest * 60)); rtc_time_to_tm(local_time, &tm);

printk(" @ (%04d-%02d-%02d %02d:%02d:%02d)\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec);

Simple setup to configure a local repository in your own machine for our own development.
The first step is to create a new user in your machine called git. You can use any other name of your choice. I have chosen the name git just for clarity in usage
$ sudo adduser git
