Rails naming conventions

General Ruby conventions

Class names are CamelCase.

Methods and variables are snake_case.

Methods with a ? suffix will return a boolean.

tmux shortcuts & cheatsheet

start new:

tmux

start new with session name:

tmux new -s myname

Enabling multicast DNS (mDNS) on a server allows other hosts on the local network to address the server as <hostname>.local.

mDNS is disabled by default in Ubuntu Server:

$ resolvectl mdns
Global: no
Link 2 (eno1): no

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

	checkf(BlueprintClass, TEXT("Cannot setup default room object with null blueprint class."));
	if (bIsDefaultSetup) return;

	TArray<const UBlueprintGeneratedClass*> BlueprintClasses;
	UBlueprintGeneratedClass::GetGeneratedClassesHierarchy(BlueprintClass, BlueprintClasses);
	for (const UBlueprintGeneratedClass* Class : BlueprintClasses)
