Fedora 31 : The twa web auditor tool.

This tool comes with a good intro: A tiny web auditor with strong opinions.
The tool named twa takes one domain at a time and use these dependencies: bash 4, curl, dig, jq, and nc, along with the POSIX system.
The project can be found at GitHub repository but I can be install easy on Fedora 31 distro:
[root@desk mythcat]# dnf install twa.noarch

The output result line looks like this:
TYPE(domain): explanation where TYPE is one of PASS, MEH, FAIL, UNK, SKIP, and FATAL., see the output example:
PASS: The test passed with flying color.
MEH: The test passed, but with one or more things that could be improved.
FAIL: The test failed and should be fixed.
UNK: The server gave us something we didn't understand.
SKIP: The server gave us something we understood, but that we don't handle yet.
FATAL: A really important test failed, and should be fixed immediately.
Another feature is scoring.
The score format is this: npasses nmehs nfailures nunknowns nskips totally_screwed.
Let's see one example:
[mythcat@desk ~]$ twa google.com | tscore

The tool can be used with Alpine Docker container.

Fedora 31 : Can be better? part 004.

The common question of any Fedora Linux user: Can be better?.
Yes, we can fix some common errors...
This is a common error generated by the GTK on Fedora distro applications:
[mythcat@desk bin]$ ./studio.sh 

(java:12631): Gtk-WARNING **: 11:45:47.061: Unable to locate theme engine in module_path: "murrine",

(java:12631): Gtk-WARNING **: 11:45:47.061: Unable to locate theme engine in module_path: "murrine",

(java:12631): Gtk-WARNING **: 11:45:47.106: Unable to locate theme engine in module_path: "murrine",
...
First, find the running GUI environment from the terminal:
[mythcat@desk ~]$ echo $XDG_CURRENT_DESKTOP
X-Cinnamon
This allows us to know that the issue may be a GTK theme package.
[root@desk bin]# dnf install gtk-murrine-engine.x86_64

Fedora 31 : Install MongoDB on Fedora 31 distro.

Today I will show you how to install the MongoDB on Fedora 31 distro. MongoDB is a general-purpose, document-based, distributed database built for modern application developers and for the cloud.
You can see the source code for MongoDb at the GitHub website.
First, you need to create a repository file.
[mythcat@desk ~]$ su
Password: 
[root@desk mythcat]# vi /etc/yum.repos.d/mongodb.repo
Add the code for this repository file.
[mongodb-org-4.2]

gpgcheck=1

gpgkey=https://www.mongodb.org/static/pgp/server-4.2.asc
Let's search this Fedora apckage with dnf tool
