Booting Debian from a RAM disk

This guide is adapted from http://reboot.pro/topic/14547-linux-load-your-root-partition-to-ram-and-boot-it/

What you need:

lots of RAM
Debian based distribution or any that supports booting from initramfs
mkinitramfs or a tool to build a new initramfs
some linux knowledge
no need to create an image
no need for Grub4Dos

Step 1: Define the Dockerfile

You'll start by creating a Dockerfile that uses an Ubuntu base image. This image will include the necessary tools for setting up an ad-hoc network and hosting a simple web server, such as iw, iproute2, and a lightweight web server like lighttpd.

FROM ubuntu:latest

# Update packages and install necessary tools
RUN apt-get update && apt-get install -y \
 iw \

Creating an Access Point on Raspberry Pi running Alpine Linux

By: XtendedGreg as seen on https://youtube.com/live/Uagq3oZrk6k

Introduction

Creating an access point with Alpine Linux on a Raspberry Pi can be an excellent project, as it allows you to extend your network or even create a new wireless network in a location where only wired internet is available. Below is a procedure to help you set up your Raspberry Pi as an access point using Alpine Linux. This guide assumes you have basic knowledge of Linux commands and networking.

Equipment Needed

Raspberry Pi (any model with Wi-Fi capability, e.g., Raspberry Pi 3/4/5)
MicroSD card (8 GB or more recommended)
Power supply for Raspberry Pi

Mount Destination partition on sdcard

lsblk -f
sudo fdisk /dev/sda
sudo mkfs -t ext4 /dev/sda1
sudo mount -t auto /dev/sda1 /mnt
cd /mnt
sudo su

mkdir -p ./etc/apk

This makes virtualbox works in a portable mode:

if you have any installed virtualbox then uninstall it first
download https://download.virtualbox.org/virtualbox/7.0.8/VirtualBox-7.0.8-156879-Win.exe or any newer or older version
click on Download ZIP above to download the scripts needed
create a folder inside your USB/external drive or whatever, name it myVMBOX (ex. F:\myVMBOX if your USB is in F:\).
inside F:\myVMBOX put the virtualbox exe we just downloaded (VirtualBox-7.0.8-156879-Win.exe) and rename it to VirtualBox.exe.
inside F:\myVMBOX put the following files start_virtualbox.bat and uninstall_virtualbox.bat, you will find them inside the zip you just downloaded.
now everytime you want to start virtualbox use start_virtualbox.bat.

The talk in the Forth2020 User-Group Zoom meeting 2022 #24 about using STM8 eForth for MODBUS nodes is here on YouTube.

If you wish to replicate the demo you should clone the STM8 eForth MODBUS code on GitHub and follow the instructions there. The code below should be placed in the root folder of this cloned repository with the indicated names.

If you have questions, please either join the Forth2020 group or open a GitHub Issue in the stm8ef-modbus repository.

This the base code with the MODBUS protocol handler loaded first (save as base):
