Raspberry Pi Time Machine and NAS Backs Up Data For You

Archiving data can save you in a pinch—but what if you forget to make a backup? This Raspberry Pi project, created by Curtis Gross, solves that problem by automating the process in a convenient NAS device. The end result is a Pi-powered time machine server with all of your data stored in archives.

Installing macOS Catalina 10.15 on Proxmox 6.1 or 6.2 using OpenCore

This tutorial for installing macOS Catalina using OpenCore has been adapted for Proxmox from Kholia’s OSX-KVM project and Leoyzen’s OpenCore configuration for KVM. You can get the full sourcecode on my GitHub here.

If you’d like to use Clover instead, use my older tutorial, but OpenCore works better!

SCP Linux – Securely Copy Files Using SCP examples

This post includes SCP examples. SCP or secure copy allows secure transferring of files between a local host and a remote host or between two remote hosts. It uses the same authentication and security as the Secure Shell (SSH) protocol from which it is based. SCP is loved for it’s simplicity, security and pre-installed availability.

SSH port forwarding (tunneling) in Linux

In this tutorial, we will cover SSH port forwarding in Linux. This is a function of the SSH utility that Linux administrators use to create encrypted and secure relays across different systems.

SSH port forwarding, also called SSH tunneling, is used to create a secure connection between two or more systems. Applications can then use these tunnels to transmit data.

If you have privacy concerns regarding Etcher (now known as balenaEtcher), here are some alternatives

We’ve used Etcher several times, mostly to make a bootable SD card for a Raspberry Pi or to put a bootable image of a Linux distribution onto a USB thumb drive. But we’re rethinking that now because we’ve read some concerns about privacy when using Etcher, or balenaEtcher as it is now called. … All we wanted to point out is that if you do have any concerns about using Etcher or balenaEtcher, there are alternatives, depending on which operating system you are using:

Seven God-Like Bash History Shortcuts You Will Actually Use

Most guides to bash history shortcuts exhaustively list all of the shortcuts available to you.

The problem I always had with that was that I would use them once, and then glaze over as I tried out all the possibilities. Then I’d move onto my working day and completely forget them, retaining only the well-known !! trick I learned when I first started using bash.

So most never got committed to memory.

Here I outline the shortcuts I actually use every day.
