History Data Structures

For stateful applications, there are 5 different ways of managing the history of state:

• No History - Living in the moment. - Examples: Any stateful application that doesn't discards all previous states upon mutation.
• Ad Hoc Snapshotting - Allows restoration to manually saved snapshots. - Examples: Memento Pattern.
• Singleton - Only remembers the previous snapshot, where undoing the undo is just another undo. - Examples: Xerox PARC Bravo.
• 1 Stack - Allows linear undo. - Examples: AtariWriter.
• 2 Stack - Allows linear undo and redo. - Examples: Browser History, Microsoft Word, Adobe Photoshop.

Here'e an example of how to register a nick on Freenode IRC. It's a little tricky, but if you follow some simple steps, you'll get through it okay. All you need to do is connect to the Freenode IRC network and have a little talk with NickServ.

The first and most confusing questions can be combined:

1. How do I know if my nick is already registered to someone else?
2. How do I talk to NickServ?

Start by connecting your client to irc.freenode.net and joining any chat.

Next, type this command in the chat window:

##The Basics

  • Joins the specified channel.
