OpenJDK 16 on Raspberry Pi OS

The OpenJDK 11 version that comes in Raspberry Pi OS’s apt repositories is ancient. It’s so old that recently people using my Minecraft Java Server for Raspberry Pi script have started getting a warning that Minecraft 1.17 will *not* support anything below OpenJDK 16.

In this article I’m going to share a sneaky trick to update your Java to a newer version than is available in apt using snapd. Let’s begin!

Pi 64bit OS - Forum Post

Last year a official 64 bit version of Raspberry Pi OS was released. There have been 3 versions of the image released with the latest one just having came out April 9th 2021.

It can be a little tricky to find and I’ve been asked in the comments here before on the site where to find it so I figured it was time to write a quick guide!

Raspberry Pi 400 Overclocking / NVMe SSD Setup Guide

Raspberry Pi 400 Setup w/ NVMe SSD

The Raspberry Pi 400 is the first offering from the Raspberry Pi lineup that is meant to approach desktop level performance. The official raspberrypi.org site lists the Pi 400 kit as the “Raspberry Pi 400 Personal Computer Kit“. It comes in the very interesting form factor of a keyboard with all the ports right in the back!

Although the performance on stock clock speeds and with a SD card was really great, especially for a Raspberry Pi, I would not call it desktop class performance. Fortunately we *can* make it desktop class performance with a few tweaks! This guide will show how to overclock the Pi 400 as well as set it up with a NVMe SSD to get the maximum possible performance we can out of it!

SSD Ubuntu 'Top' - Fixed

Native support for USB mass storage device booting has made it’s way to all of the Raspberry Pi 4’s firmware release channels! With that exciting development an old issue from the Pi 3 and earlier USB booting days has manifested itself once again in the form of a constant 1-2% CPU draw even with nothing running.

This guide will show you an easy config.txt parameter to eliminate this problem and optimize your mass storage boot setups!

Hello everyone! It has been a crazy 2020 so far and I’m way behind on articles, pull requests, issues, etc. But even in these crazy times I do have some good news: the 1.16 Minecraft update has been released and I have updated my Minecraft setup/server management script for Raspberry Pi!

Xubuntu 18.04 Desktop Screenshot

After receiving quite a few requests for a lightweight alternative to the default Ubuntu Desktop environment I have added Xubuntu Desktop to my Raspberry Pi 4 Ubuntu 18.04 LTS preinstalled image builds! The Xubuntu version feels much snappier and more responsive on the Pi. It also uses less overall memory freeing it up to do other things on your Pi.

Raspberry Pi 4 Ubuntu Server / Desktop 18.04.4 Image

Published: September 3, 2019 / Last Modified: March 2, 2023 / 322 Comments / , ,
Fine, I'll do it myself

This is a unofficial distribution of Ubuntu Server 18.04.3 for Raspberry Pi 4. It is provided with the purpose of letting us all play with the new Pi 4’s new increased RAM and other capabilities until Ubuntu’s repositories are updated with support for the newest Pi.

Once official support is released through the Ubuntu repositories this project will effectively cease to exist (until, dare I dream, the Pi 5?). The image supports KVM, has support for the Pi 4’s new 3D display driver, and can also be upgraded to a full desktop installation!

Official Minecraft Bedrock Dedicated Server on Raspberry Pi*

Minecraft Bedrock running on Raspberry Pi

One of the most requested features in my Raspberry Pi Minecraft server Raspberry Pi Minecraft server guide is support for the Bedrock edition of Minecraft. This is the edition that powers Minecraft on iOS / Android / Xbox / Nintendo Switch as well as the free Windows 10 edition.

There’s one big problem though. The official Minecraft Bedrock dedicated server is only compiled for Windows and Ubuntu X86_64. Without ARM support it seems impossible to run the Bedrock dedicated server on a Raspberry Pi. I couldn’t find a documented instance of anyone doing it anywhere.

So naturally today in this guide we are going to do the impossible. But right off the bat let me point out that there is an asterisk in my article title. Why you ask? That is because unlike my other guides this one will not yield you a well performing server. That is because we will be emulating a x86_64 processor on ARM. This is slow. VERY slow.

P4wnP1 Kali Linux

P4wnP1 A.L.O.A. is a tool for the Raspberry Pi Zero W that allows you to plug a Pi into a host computer and send remote commands and share networking with a host computer all without any user interaction. A.L.O.A. stands for “A Little Offensive Appliance”.

There’s practically no defense to this type of attack other than physically securing your USB ports. Let’s jump right in!

Raspberry Pi 4 Ubuntu Server 18.04 Installation Guide

Ubuntu Server has been my favorite Linux distribution for years. On everything but the Raspberry Pi I run Ubuntu Server but felt stuck with Raspbian on the Pi. Until now!

The Raspberry Pi 4 is now supported. Previously Ubuntu Server for Pi (like many other distros) had broken or completely missing drivers for core components such as WiFi / Bluetooth. In the 18.04.2 update the firmware for the WiFi and other components is now included out of the box making it a fully functional distribution!
