Fedora 35 : Roblox Player and Roblox Studio with Grapejuice.

In today's tutorial, I will show you how to install and play Roblox on the Linux Fedora 35 distribution using Grapejuice software.

The Grapejuice software installs protocol handlers to open games from the Roblox website and file handlers to open place files. It also provides a management interface for installing and launching Roblox.

For this, you will need to have a computer with the necessary hardware requirements for this online game.

I tested it on the old HP Compaq 6710b laptop on which I installed Fedora version 35 and it worked very hard.

Here are the Linux commands I used to install.

[mythcat@fedora ~]$ git clone https://gitlab.com/brinkervii/grapejuice

Fedora 33 : Meson build system.

Meson is a build system that is designed to be as user-friendly as possible without sacrificing performance. The main tool for this is a custom language that the user uses to describe the structure of his build. The main design goals of this language has been simplicity, clarity and conciseness. Much inspiration was drawn from the Python programming language, which is considered very readable, even to people who have not programmed in Python before., see the official webpage.

Let's test with an simple example on Fedora 33 distro.

First step, install this tool with DNF tool.

[root@desk mythcat]# dnf search meson
Last metadata expiration check: 2:20:41 ago on Thu 11 Feb 2021 08:39:26 PM EET.
============================== Name Exactly Matched: meson ==============================
meson.noarch : High productivity build system
[root@desk mythcat]# dnf install meson.noarch 
...
Installed:
  meson-0.55.3-1.fc33.noarch               ninja-build-1.10.2-1.fc33.x86_64              

Complete!

The next step is to create a C file with a simple example and one with the build file:

[mythcat@desk ~]$ mkdir CProjects
[mythcat@desk ~]$ cd CProjects/
[mythcat@desk CProjects]$ vi main.c
[mythcat@desk CProjects]$ vi meson.build

The C example file named main.c has this source code:

#include 

//
// main is where all program execution starts
//
int main(int argc, char **argv) {
  printf("Hello there.\n");
  return 0;
} 

The build file named meson.build comes with this content:

project('tutorial', 'c')
executable('demo', 'main.c') 

Use the meson with setup builddir and compile to build executable and run it.

[mythcat@desk CProjects]$ meson setup builddir

Fedora 28 : Strife another golang game framework.

Today I tested this 2D game framework named Strife.
You can read more about this from the official website.
The development team tells us:
  "This a work in progress. It provides a very minimal toolset for rendering shapes, images, and text as well as capturing user input."
This game framework uses SDL2 libraries.
Strife is open source and available under the MIT license.

Fedora 28 : Using AdonisJs web framework.

AdonisJs is a Node.js web framework with a breath of fresh air and drizzle of elegant syntax on top of it.
We prefer developer joy and stability over anything else.
I tested today this web framework named AdonisJs with Fedora 28.
The main goal was to use MySQL with MariaDB from Fedora 28 distro.
Let's start with the installation of AdonisJs on Fedora 28:

[root@desk mythcat]# npm i --global @adonisjs/cli
/usr/bin/adonis -> /usr/lib/node_modules/@adonisjs/cli/index.js
...
+ @adonisjs/cli@4.0.7
added 406 packages from 182 contributors in 33.533s

Go to the default user:

[root@desk mythcat]# exit
exit

Create the application , I named myapp:

[mythcat@desk ~]$ adonis new myapp
    _       _             _         _

This is the result of the running myapp on 127.0.0.1:3333 web address:
Let's see the folders and files from AdonisJS:

[mythcat@desk myapp]$ ls
ace  config    node_modules  package-lock.json  README.md  server.js
app  database  package.json  public             resources  start

The configuration for web files can be seen here:

[mythcat@desk myapp]$ vim  start/routes.js 
'use strict'

This is telling Adonis that when the root of the site is loaded, render a template/view called welcome.
That welcome template can be found in /resources/views/welcome.edge.

[mythcat@desk myapp]$ cd resources/

Let's see the source code of this default webpage:

[mythcat@desk views]$ vim welcome.edge 
...

For example, if you change into start/routes.js from welcome to index then you need to rename the welcome.edge to index.edge .
About css files you can make changes into public/style.css :

[mythcat@desk myapp]$ cd public/
[mythcat@desk public]$ vim  style.css


@import url('https://fonts.googleapis.com/css?family=Montserrat:300');

html, body {
  height: 100%;

}

body {
  font-family: 'Montserrat', sans-serif;
  font-weight: 300;
  background-image: url("/splash.png");
  background-color: #220052;
}

* {
  margin: 0;
  padding: 0;
}
...

Using the mysql database is simple. Into Fedora 28 distro you can use mariadb, let's install it.

[mythcat@desk myapp]$ su

[root@desk myapp]# dnf install mariadb mariadb-server
...
Complete!
[root@desk myapp]# systemctl start mariadb
[root@desk myapp]# systemctl status mariadb
● mariadb.service - MariaDB 10.2 database server
...

You need to make changes into .env file into your project folder.

[mythcat@desk myapp]$ vim .env

~

Use this changes for mariadb:

DB_CONNECTION=mysql

Install into AdonisJs with this command:

[mythcat@desk myapp]$ adonis install mysql
  [1/1] 📦  Dependencies installed [mysql]

Use this mysql commands to create the database:

[mythcat@desk myapp]$ mysql -u root

Now that our database and tables have been created, I can create a model for handling jobs table and associated data.
The next tasks to follow depends by your website:

• Creating a Model 
• Creating a Controller 
• User Authentication

Fedora 28 : The VS Code on Fedora.

The Visual Studio Code is an editor for development and includes the features you need for highly productive source code editing.
You can use this editor with many Linux distros.
Today I tested with Fedora 28 distro version.

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
sudo sh -c 'echo -e "[code]\nname=Visual Studio Code\nbaseurl=https://packages.microsoft.com/yumrepos/
vscode\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/yum.repos.d/vscode.repo'

Then use dnf to check and install this editor.

#dnf check-update
#dnf install code

Next step is to install extensions for Python, Golang, PHP, C# and more.

Fedora 27 : Go and atom editor.

The Go programming language was created at Google in 2009 by Robert Griesemer, Rob Pike, and Ken Thompson.
The Go often referred to as golang is a programming language created at Google.
Using go with Fedora 27 is very simple , just install it with dnf tool.

#sudo dnf install golang

To use it with atom editor you need to install the atom editor , see this tutorial.
The next step is to set the atom editor with the packages for go programming language, like:

• go-plus
• go-get
• go-imports
• platformio-ide-terminal

The go command come with this help:

Go is a tool for managing Go source code.

Usage:

go command [arguments]
The commands are:

build       compile packages and dependencies
clean       remove object files
doc         show documentation for package or symbol
env         print Go environment information
bug         start a bug report
fix         run go tool fix on packages
fmt         run gofmt on package sources
generate    generate Go files by processing source
get         download and install packages and dependencies
install     compile and install packages and dependencies
list        list packages
run         compile and run Go program
test        test packages
tool        run specified go tool
version     print Go version
vet         run go tool vet on packages
Use "go help [command]" for more information about a command.

Additional help topics:

c           calling between Go and C
buildmode   description of build modes
filetype    file types
gopath      GOPATH environment variable
environment environment variables
importpath  import path syntax
packages    description of package lists
testflag    description of testing flags
testfunc    description of testing functions

The next step is to install your packages with go command and get:

go get -u golang.org/x/tools/

go get -u github.com/golang/lint/golint

Let's make a simple example:

package main
import "fmt"
func main() {
    fmt.Println("Hello world !")
}

Let's test it with go command. To run the program, create a file named hello-world.go put the code in and use go run:

$ go run hello-world.go
hello world

If you want to build our programs into binaries, we can do this using go build :

$ go build hello-world.go
$ ls
hello-world hello-world.go

Finally, we can then execute the built binary directly.

$ ./hello-world
hello world

After I searched the internet I found a website with many examples and I recommend it. You can find him here.

Fedora 27 : Testing Swift with Fedora linux .

I tested today a simple instalation of this package: dnf install swift.
This install come with all additional packets required for running .
This is an application ...
First, I thought in the first phase that they implemented a programming language from Apple .
Take a look at this screenshot:

Fedora 27 : Test install with dotnet from microsoft.

Today I test how to install dotnet from Microsoft team development with Fedora 27.
The Microsoft team come with RedHat packages version - 7.3 and is an old type of packages.
They show us this old way how to deal with this issue , see this link.
I used this command lines into sudo user:

#rpm --import https://packages.microsoft.com/keys/microsoft.asc
#sh -c 'echo -e "[packages-microsoft-com-prod]\nname=packages-microsoft-com-prod 
\nbaseurl=https://packages.microsoft.com/yumrepos/microsoft-rhel7.3-prod\nenabled=1
\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > 
/etc/yum.repos.d/dotnetdev.repo'
#dnf update
#dnf install libunwind libicu compat-openssl10
#dnf install dotnet-sdk-2.0.2
#dotnet new console -o myApp
#cd myApp
#dotnet run

As you can see the dotnet working well with Fedora 27.
I would have preferred a classic dnf installation for reasons of later incompatibility.
This fact only indicates a tangential interest and a clear reason in microsoft capabilities to cover dotnet's area of interest versus linux distributions.

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:

The JetBrains I.D.E. software .

I tested the JetBrains Rider, the emerging .NET I.D.E. from JetBrains in the past.
Is good and this is new into the I.D.E. area of development.
What is this software? 
The JetBrains Rider is a new .NET I.D.E. based on the IntelliJ platform and ReSharper.
First I take a look into my Fedora distro to see it is something about JetBrains:

Fedora assembly IDE - SimpleASM.

This integrated development environment (IDE) named SimpleASM (SASM) let you to make application using assembly language.
The good part for linux users is the crossplatform IDE for NASM, MASM, GAS, FASM with syntax highlighting and debugger.
I used fasm so this help me.
The debugger is gdb - GNU Project Debugger and supports working with many opened project.
If you want to use this IDE with Fedora then you can get from Fedora 24
