Nitbit

Nitbit, the nitpicking nitwit, is my personal assistant and chat bot. It's built on the Hubot framework and deployed on a dedicated Rasperry Pi Model B+. The protype's main interface is Slack and it will have audio output and a small LCD screen.

Annoyance

Nitbit can get annoyed if memes are repeated. When annoyed, Nitbit will stop responding to most things until you apologise.

hubot Hey, the cake is a lie
hubot I'm sorry

To query annoyance state (repeated queries also rack up warnings):

hubot annoyed|annoyance

Cursing

While in curse mode, calling Nitbit names causes it to memorize them.

hubot curseout|curseoff|cursebattle on|off
hubot you are (a|an) <insult>

You can list the insults or query a word's count, or the amount of sifferent words if no word is specified.

hubot list insults
hubot insult (<insult>) count

Names

Responds to names it knows or doesn't know.

hubot My name is <name>
