As time goes by, the versions of the programs that come in the repositories of the Linux distributions become old. Similarly, program developers often release new versions with new features or bug fixes and we miss them.

Git is a program with quite active development and that requires to be always updated to have news and security fixes. So it is better to do it. And the best way to do it is to compile the source code of the application yourself.

Let us get started.

Installing the latest version of GIT on Fedora 34/33?

A great way to get the latest stable version of any open source program is to compile the source code. Don’t be frightened by the word compile, in fact it’s pretty easy to do.

Open a terminal session and install the necessary libraries to compile GIT. Some are SSL, CURL, ZLIB and others.

:~$ sudo dnf install curl-devel expat-devel gettext-devel openssl-devel zlib-devel

In a normal Fedora 33 installation the basic compiling tools are not incorporated. These tools are necessary to comply with our tutorial. To install them, run the following command:

:~$ sudo dnf groupinstall "Development Tools"

We will now proceed to download the GIT source code using wget. So make sure you have it installed:

:~$ sudo dnf install wget

And then download the GIT source code. At the time of this tutorial, the most recent version is 2.31.1. But surely in the future, it will change.

:~$ wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.31.1.tar.gz

Then, unzip the file using tar.

:~$ tar -zxf git-2.31.1.tar.gz

A folder named git-2.31.1 will be created. Access it and start the process.

:~$ cd git-2.31.1
:~$ make prefix=/usr/local all

Finally, install it.

:~$ sudo make prefix=/usr/local install

So, that is it. Just use GIT and check the installed version.

:~$ git --version
git version 2.31.1

Conclusion

GIT is a basic application for a developer and getting the latest stable version is a great help to enjoy this tool to the fullest. Let’s think that this trial will become more valid when recent versions start to come out and the version of the official repositories becomes obsolete.

If you are an application developer and need to package it for a distribution like Fedora, Debian or Ubuntu, you need some tools. Some of these tools are considered to be essential for the process.

So, all these tools are contained in the package "Development Tools“. Other important packages will be installed there. Some of them are:

• GCC the GNU C language compiler which is a mainstay for developing various languages and installing programs.
• make which allows us to compile programs from source code.
• G++ the GNU compiler for the C++ language which is widely used in QT applications.

And many more.

Install the Development and build tools on Fedora 34/ 33

These packages are not the dependencies of any program so you can install them from the source code or create new RPM packages. These packages are the basic tools that allow these operations. However, the libraries and the rest of the tools depend on each package you need to compile or create.

So, open a terminal and update the distribution:

sudo dnf update

And it carries out the installation by running:

sudo dnf groupinstall "Development Tools" "Development Libraries"

And you will see a long list of packages to be installed. All are libraries and some tools for it. But the installation doesn’t have to take that long either.

In the end, it is possible to show the versions of the most popular tools like GCC, G++, or make.

make --version

Output:

GNU Make 4.3

And now you have at least the basic packages to start the work.

Conclusion

The development and package building tools are very important in Fedora 34. Since many programs that are in the repositories depend on them and installing them can save us time.

On the other hand, they become quite necessary if we are developers or application packagers.

R is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS.In addition, it is also a very well documented language and has its own LaTeX-like documentation format.

Features

Among the advantages of R, is its great syntactic similarity with S-Plus, which has facilitated the migration of many users. Equally important is the fact that it is a language with a very active development cycle.

One of R’s strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed.

Another great advantage is that R is multiplatform, that is to say, it can be installed both in Windows and in any Linux distribution.

Let’s not talk anymore and we are going to install R programming on Ubuntu 18.04.

0. What you need

In the first place, it is necessary that you have installed Ubuntu 20.04 / 18.04 which is the recommended platform for development with this language.

It is also necessary that you have a user who can execute commands in the terminal as root.

So, let’s start.

1. Upgrade the system

In order to have the latest security patches and thus ensure the proper functioning of the system, it is necessary to make a general update to all packages.

:~$ sudo apt update && sudo apt upgrade

Now, you can continue with the installation.

2. Add GPG keys for the R repository

A simple way to install R is through APT. To do this we must add the R repository, however, first you have to add the GPG key.

:~$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

Then, add the repository.

:~$ sudoadd-apt-repository "deb https://cloud.r-project.org/bin/linux/ubuntu $(lsb_release -cs)-cran40/"

Now, you can install R programming.

3. Install R programming

Now just run the command to install R programming.

:~$ sudo apt update
:~$ sudo apt install r-base

Now, you can start to use R.

4. Verify the installation and using R

Now, it is necessary to verify the installation that we have made. To do this, type on the terminal.

:~$ sudo -i R

And you’ll see R’s console.

Now let’s make the typical “Hello World” using R.

5. Conclusion

R is not a programming language for all people or for all circumstances. On the other hand, it is a language rather oriented to manipulation of data for statistical purposes and that makes it a quite reliable alternative for your subject.

Sublime Text is well known in the world of web development. It is a powerful text editor that is widely used to develop applications in many languages. However, its main strength is in the web environment where it shows its main strength. On the other hand, it is a fairly lightweight, customizable, and extensible editor. It has everything you need to make coding a faster process like syntax highlighting, multiple selections, and a command palette.

Therefore, many users need to install it on their main Linux distribution. In this case, OpenSUSE 15.2 / 15.1 is one of the safest options to start developing any application.

Install Sublime Text on OpenSUSE 15.2 / 15.1

Sublime Text is an application that is cross-platform. That is to say, not only we will be able to install it in many Linux distributions but also in Windows or macOS. Then it is an application that is available to many people thus strengthening community support. In the same way, Sublime Text has its own repository for OpenSUSE to keep up to date.

So the first step is to open a terminal and add the GPG key for the repository.

:~$ sudo rpm -v --import https://download.sublimetext.com/sublimehq-rpm-pub.gpg

Then, once we have done the previous thing, it is necessary to choose the software channel that we deem to use. There is the Dev version where the latest version in development is hosted. It is new but can be unstable. On the other hand, the Stable channel provides only versions that are considered stable by the development team. It is the most sensible decision, so we will use this one.

:~$ sudo zypper addrepo -g -f https://download.sublimetext.com/rpm/stable/x86_64/sublime-text.repo
Adding repository 'Sublime Text - x86_64 - Stable' .......................................................................................................................................[done]
Repository 'Sublime Text - x86_64 - Stable' successfully added

URI         : https://download.sublimetext.com/rpm/stable/x86_64
Enabled     : Yes                                               
GPG Check   : Yes                                               
Autorefresh : Yes                                               
Priority    : 99 (default priority)                             

Then you can install Sublime Text on OpenSUSE 15.2 / 15.1.

:~$ sudo zypper install sublime-text

Now, you can launch from the main menu.

So, enjoy it. Remember that Sublime Text has a brother who takes care of GIT. So, you can read our post about Sublime Merge.

Sublime Merge a nice GIT client.

And that is it.

Conclusion

If you develop for the web, it is very likely that you need Sublime Text. It’s a pretty good and fast text editor. Especially in computers not so good that you need to optimize resources.

Have you used it? what did you think of the post? let us know in the comments.

Install GrunJS on Debian. The JavaScript task runner

GruntJS is a tool for executing tasks using Javascript. It allows us to have a development of quality applications, automating as much as possible the tasks and focusing on good code. This results in a decrease in coding time and the quality of it.

Some of the things we can do using Grunt if it’s configured correctly are the following:

• Concatenation or minimization of files CSS or JS.
• Optimization of images.
• The compilation ( SASS, CSS, and others).
• Unit Test.

To perform this and other tasks, GruntJS requires plugins to be installed. That’s a lot more than 3,000.

So, now we are going to learn how to install GruntJS on Debian 9.

Install NodeJS

GruntJS uses NodeJS but we do not have to learn from NodeJS. So first we will have to install it. To do that, first, we’ll get curl and then for NodeJS.

:~# apt install curl

Now, proceed to install NodeJS 12. First, add the repository.

:~# curl -sL https://deb.nodesource.com/setup_12.x | bash -

Then we can install NodeJS. However, it is necessary to install the system compilation tools. To do this, run the following command:

:~# apt install build-essential nodejs

Check the NodeJS version.

:~# node -v
v12.4.0

After that, install GruntJS on Debian 9 using NPM.

:~# npm install -g grunt-cli

Finally, check the installed version.

:~# grunt --version
grunt-cli v1.3.2

Now, let us test it.

Add GruntJS to an existing project

First, place your prompt in the project directory.

:~# cd /your-project/path

Then, run the following command:

:~# npm init

As you can see you have to answer some questions.

Now, we have to add two files to the project. First, a .JSON file where you add the metadata of the project that NPM will read later. This is auto-generated. The second one is grunfile.js where you define the tasks and plugins that GruntJS will use.

Once you have added the .JSON file, run the next command:

:~# npm install grunt --save-dev

Now, create the gruntfile.js file. And create a simple task.

:~# nano Gruntfile.js

var grunt = require('grunt');
grunt.registerTask('default', 'default task description', function(){
  console.log('hello world');
});

After that, run the task.

:~# grunt

And that is it.

Conclusion

In this post, you have learned how to install GruntJS on Debian 10 / Debian 9. The process is made easier by the fact that it depends on NodeJS and is not complicated. With this tool, you can define Javascript tasks easily.

Please share this post with your friends.

Mantis Bug Tracker is an open-source application that is used to test automated solutions, keeping a historical record of alterations and managing work teams remotely.

On the other hand, Mantis Bug Tracker allows the team to report errors and organize who can take care of them. Users are able to get started in minutes and start managing their projects while collaborating with their teammates and clients effectively.

So, let us start.

Install LAMP on Debian 10

The application has an interface that is accessible from the web. Therefore, we will have to have a working LAMP server. Remember that this software stack is made up of several elements.

To do this, read our tutorial to install LAMP.

How to install LAMP on Debian 10?

Once you have finished, you can continue with this tutorial.

Creating the database for Mantis Bug tracker

With the LAMP stack running, you need to create a new database for Mantis Bug Tracker. This is because the application needs a database manager to store all the data that is generated as it is used.

Then, you have to access the MariaDB console and create the database and the new user. So let’s go for it.

:~$ sudo mysql -u root -p 
> CREATE DATABASE mantisdb; 
> GRANT ALL PRIVILEGES ON mantisdb.* TO 'mantisuser'@'localhost' IDENTIFIED BY 'mantispss'; 
> FLUSH PRIVILEGES; 
> exit;

Now, we need to download Mantis.

Install Mantis Bug Tracker on Debian 10 (I)

At the time of writing this tutorial, the latest stable version is 2.22.1. So that is the version we will download.

:~$ wget https://sourceforge.net/projects/mantisbt/files/mantis-stable/2.22.1/mantisbt-2.22.1.zip

Then, decompress it using unzip. If unzip is no installed, you can install it using this command:

:~$ sudo apt install unzip

So, decompress the file.

:~$ unzip mantisbt-2.22.1.zip

The next step is to move the generated folder to /srv/ and change its execution permissions and owner.

:~$ sudo mv mantisbt-2.22.1/ /srv/
:~$ sudo chown -R www-data:www-data /srv/mantisbt-2.22.1/
:~$ sudo chown -R 755 /srv/mantisbt-2.22.1/

For Mantis to run smoothly, it is a good idea to create a new Apache virtual host. So, create a new file for it and add the following:

:~$ sudo nano /etc/apache2/sites-enabled/mantis.conf

<VirtualHost *:80>
        ServerAdmin admin@your-server.com
        DocumentRoot "/srv/mantisbt-2.22.1"
        ServerName bt.osradar.lan
        ServerAlias www.bt.osradar.lan
        ErrorLog "/var/log/apache2/mantisbt-error_log"
        TransferLog "/var/log/apache2/mantisbt-access_log"
        <Directory "/srv/mantisbt-2.22.1">
                DirectoryIndex index.php index.html
                Options FollowSymLinks
                AllowOverride None
                Require all granted
                Options MultiViews FollowSymlinks
        </Directory>
</VirtualHost>

Of course, replace ServerName with the one you want.

Now we can complete the installation from the web interface.

Install Mantis Bug Tracker on Debian 10 (II)

Open your favorite web browser, and go to your server. You will see this:

As you can see, the image shows all the requirements to install Mantis Bug Tracker. In this case, our Debian 10 meets all of them.

Then, we need to type the MariaDB credentials.

If everything went well, at the bottom of the page you will see the following message.

Click on the Continue link and you will see the login page.

Log in with the user administrator and the password root. The first time you log in you will be asked to either disable this account or simply change the password.

Once you change it and log in again with your password, you will see the dashboard.

So, enjoy it.

Conclusion

Mantis Bug Tracker is one of the best applications for monitoring and reporting bugs in a professional environment. So it becomes necessary in many software development organizations. Today, we have learned how to install it on Debian 10. Everything has been simple and fast.

When a new version of Ubuntu comes out many users run to install it. It is obvious because many want to get the news quickly. However, there are other users who feel somewhat lost when arriving at this new version. So they need to install some applications but they do not know how or if everything stays the same or changes. One of these applications is GIT because many developers and even novices use it for their learning. However, in Linux, there are many things that can be done in various ways and here I will show you.

In general, GIT is an open-source version control system ideal to control and manage the different versions of any application. It is widely used in the developing world for its efficiency and ease of use.

So let’s see how to do it.

Install Git on Ubuntu 19.10

1.- Using the official repositories

Git is available from the official Ubuntu repositories so we can install it with the following command:

:~$ sudo apt install git

As you can see, it is very simple. This method is the safest and most reliable, but it has a weakness. With time GIT will publish new versions with improvements and bug fixes and we will not be able to get it from the official repositories.

2.- Using the GIT PPA repository

To always get the latest version of Git available in Ubuntu, we have a PPA repository available. So, this method is recommended for more advanced users who know how to use the repositories. It is also recommended for users who always want Git news.

First, we add the repository:

:~$ sudo add-apt-repository ppa:git-core/ppa

Then, refresh the APT cache and install Git.

:~$ sudo apt update
:~$ sudo apt install git

Now you will have Git ready to be used.

Finally, check the installed version with the following command.

You can also read an introduction to the Git branches.

CakePHP it is a good framework

CakePHP is a PHP framework for web application development. It is known to be one of the easiest to learn. However, do not be fooled by its ease of learning, it is also one of the most powerful.

As expected, CakePHP is open source and is compatible with both Apache and Nginx. It also supports various database handlers such as MySQL, MariaDB, SQLite or PostgreSQL.

So let us go for it.

Install CakePHP on Debian 10

1) Install LAMP on Debian 10

First of all, you have to have a working LAMP server. As I told you at the beginning, it is also possible to run it with Nginx. However, for this tutorial, I will use Apache.

The LAMP server is absolutely necessary to “deploy” the application once finished. However, it is not indispensable for development. Although it is good to install it at once.

Read How to install LAMP on Debian 10?

Just be sure to install these PHP extensions

php-pdo php-intl php-xml php-zip php-mbstring

Now we can continue.

2) Install Composer on Debian 10

One of the best ways to install CakePHP is to use Composer. Composer is an open-source and cross-platform PHP dependency manager. It is a wonderful tool for our PHP projects.

Read, How to install Composer on Linux?

Now, we can install CakePHP.

3) Install CakePHP on Debian 10

Now we can start installing CakePHP on Debian 10. For that, we will use composer to create the project all at once.

In the terminal, run the following command:

:~$ composer create-project --prefer-dist cakephp/app myproject

Replace “myproject” by the name you want to yo your project. The installation will take some time.

If you want to use the CakePHP command, it needs to have run permissions.

:~$ cd myproject
:~$ chmod +x bin/cake

Now you can start developing your application with your favorite text editor. You can also use the project to see the changes in the web browser as if it were the real web server.

To do this, run the following command:

:~$ bin/cake server

This will make the application available at http://localhost:8765. However, we can also specify a host and a specific port with the following command:

:~$ bin/cake server -H [host] -p [port]

Now, you can open your web browser and check that everything is OK.

Note that you should never use this method to deploy the application on a real server. To do this, just upload the whole folder of your project to the root document of the server, for example /var/www/html/.

So, create a new application with CakePHP.

Conclusion

Web development is very important nowadays and for PHP it seems to be the most used and important language. It also has the advantage of having many important frameworks to be used as CakePHP. In this sense, installing CakePHP is quite simple and provides us with a great tool ready for work.

Lightweight and very efficient

This programming language was created by Alex Medvedniko, a Dutch developer who says he has a strong commitment to simplicity and performance. You can see that in V. Because V and all its libraries only occupy 400kb. Crazy! But yes, the language has ambitions and only with this size will we be able to work.

On the other hand, the language is in an early stage of development, but it shows us characteristics to which we must pay a lot of attention. Some of them are:

• Secure. Because it does not allow global variables, null values, strange behaviors of functions, nor undefined values.
• Fast. I think this is V’s main point. It can compile 1.5 Million lines of code per processor core. It’s wonderful.
• Code translation from C. If you have a project from C, you can convert the source code to V, without any problem.
• Compiler with 0 dependencies. In addition, it only weighs 400 kb.
• Hot Code Reload. It is not necessary to compile frequently to get the desired changes. Of course, in some cases yes, where there are many lines of codes.

Finally, the programming language V will have version 1.0 in December if all goes well. However, you can already do some work using it.

Getting the V programming Language

As expected, V is open-source. For now, only Linux and MacOS versions are available, but Windows will soon be added. Just download it and put it in /usr/local/bin/ to start working. You can also download the source code and build it from there.

In addition, the project tells us that it is easier to use than GO, but that it has similar documentation. On the other hand, its performance is similar to C and they plan to support graphics libraries like Vulkan or DirectX.

For now, we just need to keep an eye on this project. If you are a developer I recommend you do the same because the features are interesting.

Share this post with other friends of yours whether they are developers or not.

Android is the world’s most popular mobile operating system and is present in hundreds of models. In addition, many major brands such as Samsung bet strongly on it. So Android has an IDE that is up to the system in Android Studio.

Android Studio is the official Android IDE. It is based on IntelliJ IDEA. Android Studio offers even more features that enhance your productivity when building Android apps, such as:

• A flexible Gradle-based build system.
• A fast and feature-rich emulator.
• A unified environment where you can develop for all Android devices.
• Instant Run to push changes to your running app without building a new APK.
• Code templates and GitHub integration to help you build common app features and import sample code.
• Extensive testing tools and frameworks.

So, let us install Android Studio on Fedora 30.

Install Android Studio on Fedora 30

First of all, go to the Android Studio website. Then download the Linux version. The website recognizes which system you are using. So just click on the Download Android Studio button.

After you accept the license terms, the download will begin. It weighs 1 Gb so if you have a slow connection, it will take a while.

Once downloaded, it is necessary to install some dependencies. Open the terminal and type the following.

:~$ sudo dnf install zlib.i686 ncurses-libs.i686 bzip2-libs.i686

After that, decompress the downloaded file in /opt/.

:~$ cd /opt/
:~$ sudo tar -xvzf /home/your-user/Downloads/android-studio-ide-183.5522156-linux.tar.gz

Obviously, be careful with the path and name of the downloaded file.

Then, run the wizard.

:~$ cd android-studio/bin
:~$ sh studio

Now, you will see the wizard.

Then, choose the type of the installation.

After that, select the theme. I like the dark theme, but select what you prefer.

Next, you will see the summary.

Then, the installation will begin. The wizard will download other required components. Be patience.

The process will take time. Then, you can start a new project.

The next step is to configure the project.

Now you can start to do fantastic Android applications.

And that’s it.

Conclusion

Android Studio is an IDE for developing Android applications. Installing it is not at all complex, however, there are some dependencies that should be taken into account to avoid problems. In addition, it is recommended to have a fairly modern computer because it is somewhat heavy.
