• I completed my ZFS on Ubuntu 20.04 LTS book.
  I had an error in an actual hard drive so I added a Troubleshooting section explaining how I fixed it.
• I paused for a while the advance of my book Python: basic exercises for beginners, as my colleague Michela is translating it to Italian. She is a great Engineer and I cannot be more happy of having her help.
• I added a new article about how to create a simple web Star Wars game using Flask.
  As always, I use Docker and a Dockerfile to automate the deployment, so you can test it without messing with your local system.
  The code is very simple and easy to understand.

• I added a new article about migrating some Services from Amazon AWS EC2 to Digital Ocean using Docker, Ubuntu 20.04 LTS, Apache, PHP, MySQL.
• I added a new article about displaying a web page in PHP with the published Articles and Post Views from a WordPress Database.
• I did some changes to the web, for these changes I used my local Docker clone of Production, plus a MySQL query like:
  

mysql> UPDATE wp_options set option_value='blog.carlesmateo.local' WHERE option_name='siteurl';
Query OK, 1 row affected (0.02 sec)
Rows matched: 1 Changed: 1 Warnings: 0

This way I set an entry in /etc/hosts and I can do all the tests I want.

• I added a new section to the blog, is a link where you can see all the articles published, ordered by number of views.
  /posts_and_views.php

Is in the main page, just after the recommended articles.
Here you can see the source code.

• I removed the Categories:
  • Storage
    • ZFS
• In favor of:
  • Hardware
    • Storage
      • ZFS
• So the articles with Categories in the group deleted were reassigned the Categories in the second group.
• Visually:
  • I removed some annoying lines from the Quick Selection access.
    They came from inherited CSS properties from my WordPress, long time customized, and I created new styles for this section.
  • I adjusted the line-height to avoid separation between lines being too much.
• I added a link in the section of Other Engineering Blogs that I like, to the great https://github.com/lesterchan site, author of many super cool WordPress plugins.
