Installing Composer.phar

What is composer? Now we don’t have to reinvent wheel, we can select the tyre, the rim, the gauge. Same way in PHP we don’t have to write everything from scratch but we use Composer will give us these components so that they will work together without compatibility issues. Composer is the dependency manager for PHP. That means that chunks of php code, which are tested and each package solves one some problem are packed into a packages and added to packagist repository.

LAMP stack

What is LAMP stack? LAMP stands for Linux - Apache - MySql - PHP. This is basically everything you need to have a fully working testing server on your machine. Some parts of LAMP may already be installed on your system. If so uninstall them. I will assume, that nothing is installed, and we will install all parts of LAMP. The following steps should be same and compatible with all Debian based systems (Ubuntu is one of them).

Install SSH key

Part 2

In previous post (Part 1) I showed you how to create the SSH key pair. Today we are going to install the public key on server, that we want to use. The point of installing the Public key is to get to the target server, locate the authorized_keys file (usually in home directory inside .ssh folder) and add our public key to this file. There may be other public keys, and we shouldn’t overwrite them with our key, but to append our key at the end of file.

Generate SSH keys on Linux

Part 1

What is RSA/DSA SSH key? SSH is a cryptographic network protocol for initiating text-based shell sessions for secure data communication and/or remote command execution. This connection is useful when user isn’t physically present near the machine. As far as I know, any network service can be secured with SSH. The SSH key consist of public and private key pair. The public key is placed on computer that must allow access to the owner of the matching private key.


Hello World, Hello Blog

Welcome setInterval(function () { document.getElementsByTagName('h1')[1].style.marginLeft = (Math.floor(Math.random() * 5)) + 'px'; }, 5); I would like to present some stuff I’m working on or was working on, to show you what level of expertise you can expect from me, in case you hire me. I’m mainly a backend developer, that’s what I enjoy the most. I code web applications and style up using the latest technologies on the web (at least I’m trying to).
