In this post, we will see how can change our default shell from bash to zsh. Zsh is a shell designed for interactive use, and can offer features that bash does not have, or it is difficult to implement and add. Some of these features are: Auto Correction, Syntax Highlighting, Autosuggestions, and many more. These features can be come even more easier to add, if we use a framework for zsh, like Oh My Zsh.

In this post, we will see how we can use SFTP (Secure File Transfer Protocol) on our Ubuntu Server as a more secure protocol for FTP, in order to transfer files between the server and other clients. SFTP uses SSH in order to transfer files, so it means the connection is encrypted and as safe as an SSH connection. In order to use it the only thing we need is an OpenSSH server installed and running.

In this post, we will see how we can install an FTP server on our Ubuntu Server in order to transfer files between the server and other clients. We will use the vsftpd service, to create the FTP server and we will access it either as a new ftpuser authenticated user or Anonymously without authentication. If you are going to use the FTP service remotely on the public internet, it is best to not use Anonymous FTP, as anyone will be able to download from the server.

In this post, we will see how we can install an SSH server on our Ubuntu Server in order to access it remotely, either from the Local Network or via the internet. We will also see the setting required to make the SSH service more secure for accessing through the public internet. The following guide assumes that we have a server running in our home, on our local network, but the same can apply to a remote server running on a VPS service (like Digital Ocean, AWS, Linode, …).

In this post, we will see how we can set a static IP address on our Linux server, specifically an Ubuntu Server (Version > 17.10). Ubuntu now uses Netplan as the default network management tool to replace the old configuration file /etc/network/interfaces that we can still find in other Linux Distributions. Network Interface First we need to find the network interface name that we are connected, we can do that with ifconfig:

About This is an emulator (interpreter more accurately) for the CHIP-8, an interpreted programming language, developed by Joseph Weisbecker and used on 8-bit microcomputers in the mid-1970s. Example: Pong on the CHIP-8 emulator It was implemented as a side project to understand better a systems architecture, by implementing every assembly instruction in code. Chip-8 is a very simple 8-bit microcomputer, with a small but complete set of instructions (only 35 opcodes).
