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.
get detailed information of a package can be viewed with the ‘info’ argument;
allows us to see what has happened to our Linux system over time, and even undo, redo, or roll back a transaction;
take actions will be quicker with the ‘makecache’ argument
list all packages that are currently installed on your Linux system;
- first is check which package provides that file;
