A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Concept 1

tl;dr: Samsung is a bunch of crap company that doesn't inform their customers about serious limitations on their Wearables lineup. Great hardware, dog poo software.

So, what's this about: Samsung omits a bunch of crucial information for consumers anywhere on the Galaxy Watch product pages - at least on those for the Galaxy Watch 4, Galaxy Watch 5 or Galaxy Watch 6.

They omit on the product pages, the pages that should inform a consumer about requirements and limitations, that:

unless you're rooted, the companion phone actually must be a phone, tablets and even phablets like the Galaxy Tab Active 3 are not supported. (If you're rooted, you can patch that away. Just follow along for the guide)

Enable PipeWire on Ubuntu 22.04

This guide is only for original Ubuntu out-of-the-box packages. If you have added a custom PPA like pipewire-debian, you might get into conflicts.

Ubuntu 22.04 has PipeWire partially installed and enabled as it's used by browsers (WebRTC) for recoding the screeen under Wayland. We can enable remaining parts and use PipeWire for audio and Bluetooth instead of PulseAudio.

Starting from WirePlumber version 0.4.8 automatic Bluetooth profile switching (e.g. switching from A2DP to HSP/HFP when an application needs microphone access) is supported. Jammy (22.04) repos provide exactly version 0.4.8. So, we're good.

Based on Debian Wiki, but simplified for Ubuntu 22.04.

This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

Homebrew app ideas

OpenVPN frontend (OpenVPN itself is easily buildable and runs on webOS TVs: https://discord.com/channels/407937994037919756/835489130967859251/906943542457401395)
App autostart manager - dynamically update arbitrary app config and register it as input (see Registering an app as an input)
webos-vncserver frontend with autostart option
Package hyperiond into Piccap directly
Quick Screenshot (expose HTTP port that just returns PNG of current screen contents)

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.

Pairing Bluetooth Devices in Dual Boot with Linux Ubuntu and Windows 10/11

Introduction

This guide provides updated instructions for pairing Bluetooth devices (such as keyboards or mice) in a dual-boot environment with Linux Ubuntu and Windows 10/11, incorporating community feedback and suggestions.

Instructions

1. Pair in Linux First

Pair your Bluetooth device in Linux. This is crucial to ensure the LinkKey remains consistent.
Note: Do not re-pair the device in Linux after completing the pairing in Windows.

Pip is a package manager of python. You can download Python libraries from some Python repositories like PyPI. You can also download libraries from a git repository. This is gonna be the issue to be explained in this article.

I don't like to memorize things all the time. So, I guess, I couldn't be working without internet :). Whenever I need to install some python libraries from a git repositories, I see a lot of way to do it. It is really confusing. This should be the reason why I can't memorize it. I can see how a very simple requirement is handled with to many confusing way. There shouldn't be to many way. Some of them is not working neither. At last, I decided to blog it.

As you may know, you can use two protocols which are http and ssh to do something on git repositories. Using protocol ssh instead of http may provide some ease of use. Because of nature of ssh, you can do something with your primary/public keys. So, you don't have to input your credentials all the time. But I'll be

Introduction

Docker.app will complain about incompatible processor, so we will use Docker Machine.

Instalation

Download Docker for Mac (Docker.app). It contains some binaries that are necessary.

brew install virtualbox docker-machine
