Longhorn best practices

The following settings are provided as an example how longhorn should be configured in a production cluster, especially if it is deployed on Hetzner Cloud infrastructure.

Hetzner server nodes provide local storage and allow up to five attached volumes (with a size of up to 10TiB each) Local storage is provided by NVMe storage and therefore is much faster than the attached volumes, but limited in size (max 300GiB usable).

It is assumed that the cluster creation is already done, e.g. via terraform scripts provided by the great kube-hetzner project.

How to convert OVA to VHDX

• Rename .OVA file to .7z
• Use winrar to extract .vmdk out of it

Read here and install qemu (extract zip file)

qemu-img convert "D:\VirtualBox\Open-disk001.vmdk" -O vhdx -o subformat=dynamic "D:\VirtualBox\Open.vhdx"

Haproxy conditions

Since I keep forgetting them I've put them here.

To form a condition, you can use the following syntax after the rule that it applies to:

<HAProxy action statement> if|unless [!]acl1 <AND|OR|or|'||'> [!]acl2 ...

• if - the condition is TRUE if the result of the ACLs is TRUE.

lines between tiles, tilemap gaps:

• "all your methods except the sprite atlas are fake solutions, and will betray you when you move the camera" https://forum.unity.com/threads/the-best-way-to-fix-tile-tearing.1542956/#post-9619289
• Create sprite atlas with padding = 2 https://forum.unity.com/threads/artifacts-in-a-2d-pixel-art-scene.1427049/#post-8959284
• disable antialias
• use pixel snap shader material
• texture importer: point filter
• use unity pixel perfect camera package
• scale grid by small amount (0.999, 1.001)
• resolution issue? float camera pos
• Please try reducing the Max Texture Size to a lesser size ( 2048) and also try to have separate atlases for transparent and non-transparent sprites (non-transparent are the ones that entirely fills the texture with no transparent pixels in it). Also please ensure to have High-Quality compression for textures https://forum.unity.com/threads/sprites-have-hairline-artifacts-when-using-spriteatlas-and-mipmapping-how-to-fix.713501/#post-4774556

Preface:
I have no idea if any of this is the "right" way of doing it. This is just how I got my unit working.
Good luck.

WARNING: Do not use a V1 Waveshare display module with a stock pwnagotchi! The pwnagotchi expects a V2 module, and may irreparably damage a V1 module!
A V1 display module *can* work, but you must modify `waveshare.py` and `display.py` beforehand. For the time being, this is left as an exercise for the reader.
If you have already burnt a V1 display, try disconnecting it from the Pi and leaving it overnight. This may rejuvenate the display somewhat, but it will likely still display signs of damage.

Installation:
1. `dd` Raspbian Lite to an SD card.

Setting up RetroArch on Raspberry Pi 4 and building emulator cores

Guide for myself and others to get RetroArch running on the new Raspberry Pi 4 while projects like RetroPie get an image out for the rpi4.
Disclaimer: I am not an expert and this may not be the most optimal build possible, but it works.

Inspiration taken from:

• This gist showing the basic steps for building and configuring for raspberry pi 3. I'm new to Raspberry Pi and RetroArch myself so this was super helpful and I recommend looking through it.
