Today I made my first AWS Certificate and I want to share this.

I have to login to AWS Certification with my APN account. There I had to create a ne CertMetrics account on the first visit, that automatically got connected with my APN account. Afterwards I can open the CertMetrics page, where I had to enter some information about me first. Then I could go to the Digigal Badges section, where I had to sign in to another Platform: Credly's Acclaim Platform, to create another new account.
On my Credly's page I cannot see any badges or certificates.

Now I have two additional accounts, CertMetrics and Credly's, but still can not share my certificate.
Maybe it is not possible to share this certicate, maby I have to do the AWS Cloud Practicioner certificate first to share something?


Real Bug

In my second Blogpost I wrote about a bug, that was not a bug, but then I had to figure out, that there is a bug.

The syntax hightlighting is working while editing a blogpost or viewing it as single post. But not on the home page. To enable it on the home page I had to change the 'Enable Code Block on Home Page' setting. Works fine.

I wrote my second Blogpost about this and then the syntax highlighting was gone again.

I disabled the second post: The syntax highlighting of the fist post was there again.
I enabled the second post again: The syntax highlighting of the fist post was gone :'(

Next test:
I added block of code in my second post.
The code of the second post was highlighted on the Home Page. And also the code of the first post on the Home Page!

I removed the block of code from my second post and added this cool piece of code to this post:

10 PRINT "Hello World"
20 GOTO 10

Now the syntax hightlighting works on home page for this (third) post and the first post.
As long as the first post on the home pages has a code block, the code blocks of all posts on the home page will work.

So if you see an post on my home page without syntax highlighting, just wait until I write a new post with a piece of code or open the single post page.


First Post – First “Bug”

I made my first Blogpost and I found a bug, that the code snipet was highlighted while I was editing the post or in preview mode. But when I open it for example on my mobile or in private mode or just in the same browser in "normal" view, the syntax hightlighting was gone.

This is how it looks in edit or preview mode:

Preview Mode

And this is how it looks in "normal" mode:

Normal Mode

I thought, this would be a bug, but at the end it turned out, that this is a feature.

I contacted the Plugin Author through the support forum and this is his answer:

"It's not a bug, it's a feature"

I followed his instructions and now the sourcecode shines highlighted as expected!

WordPress Blog


I want to start a blog to note down some development stuff I do, therefore I want to test, if WordPress might be a good choice to quickly and easily setup an own blog.

Testing WordPress is pretty easy if you can use Docker.
There is a good documentation how you can do this.
In short: Only create one docker-compose file and start it up.

cd my_wordpress
nano docker-compose.yml
docker-compose up -d &
version: '3.3'
     image: mysql:5.7
       - db_data:/var/lib/mysql
     restart: always
       MYSQL_ROOT_PASSWORD: somewordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress
       - db
     image: wordpress:latest
       - "8000:80"
     restart: always
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
       WORDPRESS_DB_NAME: wordpress
    db_data: {}

Just open http://localhost:8000 to create a user and start testing WordPress.

I tried the Code Syntax Block Plugin first, but then I was more satisfied with the CodeMirror Blocks Plugin.


Create sub-domain, install WordPress with CodeMirror Blocks Plugin, Sample Content deleted. Done 🙂

As last part of installation I added a "K" graphic from Icons8 as favicon.
