Fedora 28 : Linux application with node.js and Electron packager.

Today I make a tutorial about how to use node.js and Electron packager to create cross-platform applications.
The tutorial show you how to create Windows, Linux and Mac OS cross-platform applications and can be found here.
This is result of running the linux application with Fedora 28:

Fedora 28 : Godot example with linux .

Today I tested a simple example with the game engine named Godot version 3.0.6.
It was created on a Windows 8.1 operating system and exported as a linux application.
I moved the two files to the Fedora 28 operating system.

The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the `/usr/lib/mono/4.5/mscorlib.dll' directory.

The error occurred from the mono package and I fixed it with the installation using the dnf tool.

[root@desk mythcat]# dnf install mono-core.x86_64

Fedora 28 : Unusual arguments for the dnf command.

Today I will introduce you in this tutorial some more unusual arguments for the dnf command.

• first is check which package provides that file;

[root@desk mythcat]# dnf provides /etc/httpd/conf/httpd.conf

• get detailed information of a package can be viewed with the ‘info’ argument;

[root@desk mythcat]# dnf info httpd

• allows us to see what has happened to our Linux system over time, and even undo, redo, or roll back a transaction;

[root@desk mythcat]# dnf history
ID     | Command line             | Date and time    | Action(s)      | Altered
-------------------------------------------------------------------------------
   178 | upgrade                  | 2018-08-01 09:33 | Update         |   27

   176 | upgrade                  | 2018-07-30 20:43 | Update         |    1

• take actions will be quicker with the ‘makecache’ argument

[root@desk mythcat]# time dnf makecache
