Fedora and childish ideas .

The marketing, design and promotion of any product is a key element of success.
I have to admit that although I am not an active member of Fedora distribution teams and I am glad to be able to help where it is needed.
Over the last time, I spend my online time with my son playing Roblox ( because he is away from me) and trying to show him what the computer can do for people.
This game allows development with the LUA programming language and object creation for users.
The idea that programs and games are essential factors in our lives.
Also the fact that I have been using Fedora for a long time, I have allowed myself to implement an intention to promote the Fedora distribution.
This is a shirt created with the Fedora logo and can be worn in the Roblox game. He found it here.

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:
