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;

Fedora 28 : Using the python module sh .
Today I test another python module named sh with python version 3.6.5 and Fedora 28.
This python module named sh is a full-fledged subprocess replacement for Python 2.6 - 3.5, PyPy and PyPy3 that allows you to call any program as if it were a function.
You can read bout this python module here.
I used dnf tool to search and install the pip tool :

Fedora 28 : Starting develop with Flutter .
Today I started with another programming language Dart and Flutter.
The development team tell us about Flutter:
Flutter is Google's mobile UI framework for crafting high-quality native interfaces on iOS and Android in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
You can read more about this on official webpage:
About linux setup you can read here.
You need also to download the Android Studio I.D.E from official webpage.
You need to install some packages using dnf tool:
You need to install Dart and Flotter plugins, use search:
Download and unarchive the Flutter from official webpage.
Next steps is to set the path for the Flutter and make settings for android licenses:
Use flutter command to get more help :
You need to have all settings for your devices or emulated AVD devices to build and develop your android application.

Fedora 28 : The Powertop tool from Intel.
The Powertop is a tool provided by Intel to enable various powersaving modes in userspace, kernel and hardware.
Using this tool is possible to monitor processes and show which of them are utilizing the CPU and wake it from its Idle-States.
The tool allowing you to identify applications with particular high power demands.
The name of this tool powertop.x86_64 come from : Power consumption monitor.
Let's install and set this tool to Fedora 28 distro linux:

Fedora 28 : Godot game engine.
Today I tested the new version of Godot game engine - version 3.0.3 .
You can download it from official webpage.
I used the 64 bit version.
After download and unzip you can run the binary file in your user terminal.
The Godot game engine start with a GUI.
Into the right area of screen into Scene tab two objects: Spatial and Camera.
You need to select or add a WoldEnvironment node.
Take a look to the Inspector and use with New Environment .
Run this with the play icon.
If is all right you can see something like this:
Create e new folder into your project and name it Export.
Copy the mscorelib.dll into this folder.
Go to main menu and select Project - Export and you will see this GUI for export your game.
Press Add button to select Linux/X11 output:
Select Linux and press Export Project button.
Go to Export folder and run from your linux terminal your game.
This game engine working well with Fedora 28 and the export running without errors.
