An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

	abstract class UserWSEndpoint[F[+ _]: Timer: Concurrent: ContextShift](
	broadcastTopic: Topic[F, PushNotification])(implicit F: ConcurrentEffect[F])
	extends Http4sDsl[F]
	with Loggable {

	def broadcast(e: PushNotification) = broadcastTopic.publish1(e)

	def toText[A: Encoder](a: A)(implicit e: Encoder[A], wse: Encoder[WSMessage]) =
	Text(wse(WSMessage("", "", e(a).some, "", "".some)).asString.get)
