Undocumented Paper startup parameters

I didn't find any website of these parameters so I decided to document these on my own. I don't know if there's more of them but atleast there are some now... Idfk why some of these are prefixed -DPaper instead of -Dpaper but I don't care enough tbh.

`-Dpaper.explicit-flush` Explicit Network Manager flushing (default: false)

Disables explicit network manager flushing. By default as it seems to work fine without flushing. You should only enable this if issues arise. Uses improved logic of doing the flushing on netty event loop instead on the main thread.

`-DPaper.maxSignLength` Limit Client Sign Length (default: 80)

Limits data that can be sent to signs as modified clients can send much more data compared to vanilla clients. Only impacts data sent from the client.

Fabric/Quilt Server Optimization

This has updated for 1.20.4, all of the optimization mods mentioned here are compatible with each other and don't affect vanilla behaviour by default.

Recommended Paper Anti-Xray settings by stonar96

General

Anti-Xray can be configured per world in the paper.yml configuration file. To understand how per world configuration works please read this first. Note that after changing any settings for Anti-Xray you have to restart your server. Executing the /reload command (you should never do this) won't apply the settings to worlds that are already loaded.

Enable experimental features in Docker

Using --squash requires a Docker with and API version greater than 1.13 (can be checked with docker version).

Edit /etc/docker/daemon.json adding:

"experimental": true

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

Renew GPG key

Given that your key has expired.

$ gpg --list-keys
$ gpg --edit-key KEYID

Use the expire command to set a new expire date:

This is a quick guide of the commands we use to sign someone's GPG key in a virtual key signing party.

Note: The steps cover only the technical aspects of signing someone's key. Before signing someone's key, you must verify their identity. This is usually done by showing government-issued ID and confirming the key's fingerprint

The commands will work for both GPG and GPG2.

I use Julian's key for the examples. His key id is 2AD3FAE3. You should substitute with the appropriate key id when running the commands.

Signing the key

List the keys currently in your keyring: gpg --list-keys.

	#tabbrowser-tabs {
	min-height: 33px !important;
	}

	.tab-label-container {
	height: 29px !important;
	}

	/** Add small space at the top */
	.tab-stack {

	# ~/.bashrc: executed by bash(1) for non-login shells.

	# If file exists (likely) copy fragment below into existing script:

	# If stdin is a terminal
	if [ -t 0 ]; then
	# Set GPG_TTY so gpg-agent knows where to prompt. See gpg-agent(1)
	export GPG_TTY="$(tty)"
	# Set PINENTRY_USER_DATA so pinentry-auto knows to present a text UI.
	export PINENTRY_USER_DATA=USE_TTY=1

	With this script you can turn your jar file into a service on linux.

	Change the MATH constant to the name of your application and make sure you are correctly specifying
	the locationsof the files used in the variables.

	For the correct operation of the script install it in the directory init.d and release its access as below:

	chmod 755 your_script
