In Drupal 8 module development, we can easily create a table with pager. The code might be different from the one we use in Drupal 7, but it's still quite simple. I assume you have already learned to create a simple Drupal 8 "Hello World!" module as explained in there. So, let's start to create the table with pager. For example, we have a routing file, mydemo.routing.yml like the following.
Slackware has a very simple way to enable some system services to start automatically at system startup. As it said in the following documentation, Slackware is using BSD-style for its init system. All of the system initialization files are located at /etc/rc.d folder. When we want to enable a certain system service to start automatically, we just need to change the file mode into executable. For example, the Apache web server init file is rc.httpd.
What is Git? And why should we use it? Git is a source code management software, that able to track the revisions in our source code. We usually call that kind of software as the revision control. Most people use revision control like Git or Subversion (SVN) when they are working as a team to develop one software together. That's good because they can always get the updates from everyone in the team and see what others have modified. But, the revision control is not only needed when we are working in team.
