Category theory jargon cheat sheet

A primer/refresher on the category theory concepts that most commonly crop up in conversations about Scala or FP. (Because it's embarassing when I forget this stuff!)

I'll be assuming Scalaz imports in code samples, and some of the code may be pseudo-Scala.

Functor

A functor is something that supports map.

class ChatRoom(roomId: Int, actorSystem: ActorSystem) {

  private[this] val chatRoomActor = actorSystem.actorOf(Props(classOf[ChatRoomActor], roomId))

  def websocketFlow(user: String): Flow[Message, Message, _] = ???

  def sendMessage(message: ChatMessage): Unit = chatRoomActor ! message

}

Exposing a directory on the host machine to an LXC container

1. Log into the container and create an empty directory, this will be the mount point
2. Log out and stop the container.
3. Open to your container's config file
   • For regular LXC containers: /var/lib/lxc/mycontainer/config
   • For unprivileged LXC containers: $HOME/.local/share/lxc/mycontainer/config
4. Add a new line above the lxc.mount directive, that follows the format below. Substitute proper paths as necessary:
   • lxc.mount.entry = /path/to/folder/on/host /path/to/mount/point none bind 0 0

• Both of these paths are relative to the host machine.

// Тайпкласс Animal (для полноты картины добавил метод hello, иначе был бы совсем тривиальный пример)
// Animal полностью абстрагирован от низлежашего типа A
trait Animal[A] {
  def word: String
  def talk() { println(word) }
  def hello(a: A): String
}
 
// Обертка над тайпклассом Animal, чтобы можно было писать cat.hello, а не animal.hello(cat)
// AnimalOps полностью дублирует методы, определённые в Animal, но также может содержать еще и дополнительные методы.
