Big things happen when computers get smaller. Or faster. And quantum computing is about chasing perhaps the biggest performance boost in the history of technology. The basic idea is to smash some barriers that limit the speed of existing computers by harnessing the counter-intuitive physics of subatomic scales.
Quantum computing is an area of computing focused on developing computer technology based on the principles of quantum theory, which explains the behavior of energy and material on the atomic and subatomic levels. Quantum computers could spur the development of new breakthroughs in science, medications to save lives, machine learning methods to…
Lumen is an open-source PHP micro-framework created by Taylor Otwell as an alternative to Laravel to meet the demand of lightweight installations that are faster than existing PHP micro-frameworks such as Slim and Silex. With Lumen, you can build lightning-fast microservices and APIs that can support your Laravel applications.
Lumen utilizes the Illuminate components that power the Laravel framework. As such, Lumen is built to painlessly upgrade directly to Laravel when needed. These are some of the built-in features of Lumen:
Linux is the best-known and most-used open source operating system. As an operating system, Linux is software that sits underneath all of the other software on a computer, receiving requests from those programs and relaying these requests to the computer’s hardware.
This open source cooperation among companies and developers has led to making Linux one of the best ecosystems for use from small digital wristwatches to servers and supercomputers. Based on statistics, there are at least 100 companies and more than 1000 developers who work together for every kernel release. Linux is composed of a kernel, the core control software…
I’m going to guide you how to deploy and host your React app with Netlify.
Netlify is a service that automates builds, deployments and manages your websites. It’s one of the fastest and easiest deployment solutions these days.
So far I have only used Heroku to deploy my web applications. Well, that changed today as I decided to branch out and try a different deployment service. I love Heroku, and it is so easy to use, but I hate how my applications go to sleep after 30 minutes of inactivity unless you pay a monthly fee. The sleeping application then…
Rust is a language empowering everyone to build reliable and efficient software.
The Rust programming language helps you write faster, more reliable software. High-level ergonomics and low-level control are often at odds in programming language design; Rust challenges that conflict. Through balancing powerful technical capacity and a great developer experience, Rust gives you the option to control low-level details (such as memory usage) without all the hassle traditionally associated with such control.
Rust is a low-level statically-typed multi-paradigm programming language that’s focused on safety and performance.
Rust solves problems that C/C++ has been struggling with for a long time, such…
Docker is an application that makes it simple and easy to run application processes in a container, which are like virtual machines, only more portable, more resource-friendly, and more dependent on the host operating system.
In this article, you’ll learn how to install and use it on an existing installation of Ubuntu 18.04.
Note: Docker requires a 64-bit version of Ubuntu as well as a kernel version equal to or greater than 3.10. The default 64-bit Ubuntu 18.04 server meets these requirements.
Note: All the commands in this tutorial should be run as a non-root user. If root access is…
sudo apt-get remove –purge php*
sudo apt-get purge php*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get remove dbconfig-php
sudo apt-get dist-upgrade
Note: The output of the below command will provide you with information the installed package software, version, architecture and short description about the package. grep command is used to find the PHP package
sudo dpkg — get-selections | grep php | cut -f 1
sudo apt-get remove — purge <package name from the previous command output>
sudo whereis php
sudo rm -rf <directory/file path from the previous command output>
sudo service apache2 stop sudo apt-get purge apache2 apache2-utils…
I’m running all the steps in this tutorial with root privileges, so make sure you’re logged in as root:
To install MySQL 5.7, execute this command:
apt-get -y install mysql-server mysql-client
The packages mysql-server and mysql-client are so-called ‘meta-packages’, they install always the latest MySQL version that is available from Ubuntu. The latest version is currently MySQL 5.7. We have set the root password for MySQL already during installation, but I would like to remove the anonymous user and test database for security reasons. Run the mysql_secure_installation command below to achieve that.
mysql_secure_installationEnter password for user root…
The LAMP stack is the foundation for Linux hosted websites is the Linux, Apache, MySQL and PHP (LAMP) software stack.
Linux based web servers consist of four software components. These components, arranged in layers supporting one another, make up the software stack. Websites and Web Applications run on top of this underlying stack. The common software components that make up a traditional LAMP stack are:
Linux: The operating system (OS) makes up our first layer. Linux sets the foundation for the stack model. All other layers run on top of this layer.
Apache: The second layer consists of web server…
