The easiest languages to start programming

If you are looking to test your application development skills, it is best to start learning slowly. Here are some of the programming languages that are especially suitable for beginners.

• Ruby: if you have zero knowledge in everything related to software development, this is one of the most interesting proposals you will find. It could be considered one of the most fascinating and affordable languages to start programming. Despite being a veteran proposal, we must consider that since its inception, it was designed to facilitate the arrival of new programmers. This allows us to begin to understand structures and execute examples from the beginning.

• JavaScript: on the other hand, we find a proposal that is more than familiar to most people. In fact, you have probably heard of it. In addition, it offers a good number of professional opportunities. Therefore, it is one of the most widespread and used alternatives to learn to program. A point in its favor is that we can work with this language on all types of platforms, both mobile and desktop.

• Python: if you are a complete novice in this sector, Phyton is one of the most affordable proposals. It is generally used in both web and desktop projects. Moreover, it has been growing steadily over the last few years. Certainly, it is easy to learn. However, we must also consider that this language is very widespread in everything related to artificial intelligence. It is characterized by its object-oriented programming and easy-to-understand structures.

Conclusion

Very well, in this way we have seen some of the easiest languages to learn to program from scratch. Keep in mind that this choice depends on several factors. Indeed, exactly what you want to program influences a lot. This way you can make the right choice. However, I can assure you that these languages are the best way to start. Bye!

To quote the website of this programming language:

Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada, and Modula.

This gives us a pretty good idea that the language meets everything needed to create modern applications.

Like all modern languages, it has versions for Windows, Linux, macOS, and BSD. This makes it possible to run on almost all current systems. This also makes it possible for the programmer to choose the environment where he feels best.

Nim is an object-oriented language with a syntax similar to Python‘s with even similar characteristics.

So, let us get to work.

Installing Nim programming language on Ubuntu 20.04 / Debian 10

In Ubuntu 20.04 / Debian 10 Nim is included in the official repositories. Therefore the installation becomes quite simple and is summarized too in

:~$ sudo apt install nim

However, this method is not recommended because the latest Nim version is not installed.

So there is another method that allows us to install the latest stable version, but also the development version.

To install it, there is a script that we have to download and run but first, we have to install the Debian compilation packages.

So, open a terminal and execute the following command

:~$ sudo apt install build-essential

In case curl is not installed you can install it with the following command:

:~$ sudo apt install curl

Then have Nim installed. We have to make it available throughout the system.

So edit the ~/.profile file:

:~$ nano ~/.profile

And add the following:

export PATH=/home/your-home/.nimble/bin:$PATH

Replace "your-home" with your username or home.

Save the changes and close the file.

Appley the change by running:

:~$ nim -v

Testing Nim Installation

Now it is time to test if the installation has worked.

So we’ll create the classic test program by displaying a message. This will serve the purpose.

The code files for the Nim language, they have a nim extension. So we will create one:

:~$ nano hello.nim

And within this file add the following content:

echo "Hi, Osradar"

Save the changes and close the file.

Now, compile the source file to generate the executable binary.

:~$ nim c hello.nim
Hint: used config file '/home/angelo/.choosenim/toolchains/nim-1.2.0/config/nim.cfg' [Conf]

Remember that you have to specify the source file but also the full path.

Then, run it as follows:

~$ ./hello

So now we know that nim works and you can start working with him.

Conclusion

Programming is very important nowadays, so it requires programming languages to match. Today we have taught you how to install Nim on Ubuntu 20.04 / Debian 10 so you can have an ideal partner to make your applications.

Downloading RubyInstaller

As mentioned in the title, we’ll be using RubyInstaller to install Ruby on Windows 10. In the first place, go to the RubyInstaller page. In the download section, please choose the version corresponding to your computer’s architecture. At the time of writing this post, the most recent version is 2.6.5.-1.

Once the installer is downloaded, simply run it to start the installation.

The following box shows various configuration options. It’s a good idea to check all of them since this adds Ruby to the PATH, as well as associates the .rb and .rbw files with the Ruby installation. It is also possible to choose UTF-8 as the external encoding parameter.

However, some gems or packages require compiling in C, so select the option to install MSYS2.

Once all the preparations have been made, the wizard will start the installation.

Wait a few seconds while the assistant does his job. Finally, select the option to run the ridk install. This will install the MSYS2 and the development toolchain.

A new window will be displayed immediately to continue the installation. Please leave everything by default to execute a full installation. Press enter to start the process.

After a few minutes, the word success will appear in the window. This means that the installation was completed. Please close the window.

Runs the interactive mode in Ruby

To check the performance of the Ruby interpreter, simply open a CMD and run the following command:

irb

To exit, simply type the following command:

exit

Ultimately we have seen how to install Ruby on Windows 10. From now on you can use this powerful programming language. Before I say goodbye, I invite you to check out our post about Django on Windows 10.

As we know, PHP is a programming language widely used all over the world. In fact, most of the web sites and applications use it. Therefore, it is to be assumed that most servers need it.

By default, CentOS 8 includes version 7.2 in its official repositories. It’s actually a good version that will be supported for a while longer, but the language is advancing more and more every day. So, it is a good idea to install recent versions.

So, let us start.

Install PHP 7.4 on CentOS 8

Installing Apache web server on CentOS 8

Okay, the first step is to install a web server. It can be Apache or Nginx but in this case, I will use Apache. So I am going to install it.

Open a terminal session and run the following:

:~$ su
:~# dnf install httpd

After the installation is completed, the apache service must be started. We can also enable it to start together with the system:

:~# systemctl enable httpd
:~# systemctl start httpd

Then, you have to open the ports where the server works. Without this, we won’t have access to the documents on the server.

:~# firewall-cmd --add-port=80/tcp --permanent --zone=public
success
:~# firewall-cmd --add-port=443/tcp --permanent --zone=public
success
:~# firewall-cmd --reload
success

Now, we can install PHP 7.4 on CentOS 8.

PHP’s turn

To install PHP 7.4 we will use the REMI repository. It is quite stable and has a long history of use. But, first, we will have to enable the EPEL repository. We can do this with the following command:

:~# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Next, we proceed to add the REMI repository for CentOS 8.

:~# dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm

The REMI repository contains a large number of packages. By default, only those belonging to REMI-Safe are enabled. So, you have to enable REMI-7.4.

:~# dnf module enable php:remi-7.4

And now we can install PHP 7.4 and its modules without problems.

:~# dnf install php php-common php-pecl-apcu php-cli php-pear php-pdo php-mysqlnd php-pgsql php-gd php-mbstring php-xml

Now we are going to prove that it all worked out. The best way to do this is to run PHP.

So, I am going to create a file called test.php in the apache root folder and add the phpinfo method to it.

:~# nano /var/www/html/test.php

Save the changes and close the editor.

Then, restart the apache service:

:~# systemctl restart httpd

Now open your web browser and go to http://your-server/test.php and you will see the following:

So, enjoy it.

Also, you can read all the features of this version in this link.

The post How to install PHP 7.4 on CentOS 8? appeared first on Linux Windows and android Tutorials.

PHP is very known. This web-oriented language is widely known for its ease of learning and its power. Fortunately, PHP development is quite active and from time to time we have a new version that helps to improve the stability and security of the applications made with the language. Then, it is convenient to develop with recent versions of the language. Or in the case of servers, it is convenient to have updated libraries and languages so that new applications can run correctly.

Well, let’s get started.

Install PHP 7.3 on CentOS 8

First of all, I always recommend updating the operating system completely, before performing any operation on it.

Open a terminal and run:

:~$ su
:~# dnf update

Now you will have a more secure system thanks to the security patches installed during the upgrade.

PHP 7.3 is available thanks to the REMI repository. The problem is that this repository depends on the EPEL repository. This repository must be enabled.

To enable the EPEL repository, just execute the following command:

:~$ rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Once the corresponding package is installed, the EPEL repository will be activated. It’s that simple.

Then, we can enable the REMI repository which is where PHP 7.3 is. To do this, just use this command:

:~$ dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm

REMI is a fantastic repository because it has several versions of PHP available. In this case, we are interested in version 7.3. To enable this “section” of the repository, use the following command:

:~$ dnf module enable php:remi-7.3

Now, you can install PHP 7.3 with the following command:

:~$ dnf install php php-cli php-common

This command will install the most basic language as the interpreter. Remember that if you are going to develop or serve applications you have to install the necessary PHP modules.

Finally, you can verify the installed version with the following command:

:~$ php -v

And ready, you can continue installing the PHP modules you need. And start working.

Conclusion

Installing PHP is not complicated in almost any current Linux distribution, however, it is convenient to have recent versions that help improve the fluidity of the system. For this, we use an external repository to provide the packages that by default the distribution does not give us. Today you have learned to install PHP 7.3 in CentOS in a fast and simple way.

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.

Linux server-oriented operating systems use not-so-current versions of the basic packages because they are the most tested. This situation has as main advantage that the packages that are in the official repositories are very stable; however, not having the latest versions of the packages means that new features are not always available.

With this in mind, it’s easy to assume that some essential applications can’t be used without updating some key packages like PHP. For example, the latest stable version of Laravel requires PHP 7.1.3 but Debian 9 brings in its repositories version 7.0.

In others words, there are times when it is necessary to update some essential packages. Today it’s PHP’s turn on Debian 9.

Why you need

The process is quite simple, however, you must execute commands as a superuser. To do this, you can use a user with sudo enabled or directly be root.

You also need to be somewhat familiar with the use of the terminal, as we will do everything through the command line interface.

With this in mind, you can get started to install PHP 7.2.

Let’s get to work

Now that you have decided to update PHP, the first thing is to update the system. With that, you will get the versions of the packages but only those related to security. Anyway, it’s a good idea to do it. Run:

:~$ su

Then, enter your password to become root. Now, run:

:~# apt update && apt upgrade

That’s enough.

So, you can check this by executing the following command:

:~# apt-cache show php

As you can see, Debian 9 comes with PHP 7.0 by default.

The next step is to install some necessary packages such as: apt-transport-https lsb-release and ca-certificates.

:~# apt install apt-transport-https lsb-release ca-certificates

To install PHP 7.2 you need an external repository. Run:

:~# wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg

Next:

:~# sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'

Then, proceed to update the repository cache.

:~# apt update

Now, search the repository database for the PHP package and you’ll see that version 7.2 is available.

And proceed to install the PHP 7.2 packages you want. I’ll install these for now.

:~# apt install php7.2 php7.2-common php7.2-cli php7.2-mysql php7.2-xml php7.2-curl

Finally, you can check the installed version. To do this, run.

:~# php -v

Conclusion

In the final analysis, it can be said that having old and tested packages has its advantages but from time to time it is convenient to update them. Especially if other applications make use of them like Laravel with PHP.

Installing PHP 7.2 in Debian 9 is simple and it is recommended to do it to have important security updates especially if the server works a lot with web applications.
