Just the normal 2160p is probably what you want, remuxes are going to get very large with marginal benefit. You might have trouble if you're using the built-in smart tv app for plex, but the plex app on chromecast will keep up fine.

KeePassXC and Keepass2Android auto-synced with my Nextcloud instance. Works great cross-platform for Linux/Windows/Android.

Go is exclusively pass-by-value. That means each function receives a copy of the value of what you passed in. No exceptions.

Except there are several exceptions... Maps are always pass by reference, even if you don't explicitly pass them as a pointer. Same with slices, channels, and interfaces. Good article otherwise though.
