Fedora 27 : load81 simple lua game engine .

Today I tested something simple with Fedora 27 and scheduling in.
This is a SDL based Lua programming environment for children called load81.

The author teel us:

The name Load81 originates from the fact that in popular Commodore home computers the command LOAD "*",8,1 would load the first program on the disk starting from the file-specified memory location.

Load81 is written in ANSI C and uses SDL and SDL_gfx and SDL_image libraries.
I installed all these libraries and everything worked very well.
Once taken from github with clones I tested the examples in the examples folder and worked well from the first time.
The examples folder come with simple examples and some simple games.
Create your lua script and use this command to run it:
./load81 example.lua
All running scripts require a graphical display account.
They worked very well on my normal account and I got a run-time error on my root account.
From examples, I took the triangles.lua script to illustrate how this game engine looks and works.

function setup()
    background(0,0,0);
end

function draw()
    fill(math.random(255),math.random(255),math.random(255),math.random())
    triangle(math.random(WIDTH),math.random(HEIGHT),
             math.random(WIDTH),math.random(HEIGHT),
             math.random(WIDTH),math.random(HEIGHT))
end

This is screenshot of triangles.lua script:

Fedora 27 : lua programming with torch and love 2d.

The Lua programming language is a good programming tool to start and test your programming skills.
Lately, the capabilities of computers and computer networks have increased exponentially.
The programming language allows the user simple programming possibilities with essential advantages.
I will illustrate some programs and frameworks that may be of special interest to you:
  • Wireshark has an embedded Lua interpreter and you can be used to write dissectors (to decode packet data), post-dissectors and taps;
  • Torch is a scientific computing framework with wide support for machine learning algorithms;
  • Love 2D is a framework for making 2D games for windows, linux and android;
Today I start with install lua , torch and love 2D.
This work very well. If you use root accont then love command will work only with display SDL. This means you have to use a normal user, not a root user.
I used dnf install tool for lua and love 2d and github for torch.
The result can be seen in the following screenshots:

News: About the new Fedora 27 .

Today I tried to make a simple installation of Fedora 26 which I did without problems.
After that, the software update come with the option to upgrade all of your Fedora system software to the new Fedora 27.
The work of the Fedora team is appreciated for the work being done to create this new version.
For those who have been following the evolution of the design team over the course of Fedora's development, they will see evolution and quality in the new Fedora design.
Most software used by me was implemented without errors and everything seems to work very well.
Here are some screenshots made during the installation process:
