Dog
Dogs communicate through an elegantly simple vocabulary of approximately ten to fifteen distinct signals. Tail wagging indicates happiness. Ears flattened signal concern. The play bow represents an unambiguous invitation to recreation. Sitting beside an empty food bowl whilst staring meaningfully communicates hunger with a clarity that transcends language barriers. There is no subtext. There are no hidden meanings. What you see is precisely what the dog means.
This transparency extends to their desires. A dog who wishes to go outside will communicate this through methods of escalating obviousness until the message cannot possibly be missed.
Programmer
Programmer communication operates through layers of semantic complexity that would challenge professional cryptographers. The phrase it works on my machine contains multitudes. The statement it should be a quick fix carries implications of timeline disaster. The word interesting, when applied to code, functions as a euphemism requiring years of exposure to decode accurately.
Documentation, theoretically created to clarify communication, often achieves the opposite. Studies of software projects reveal that 54 percent of documentation contradicts the actual behaviour of the code it describes, creating what researchers term optimistic fiction.
VERDICT
Dog communication is transparent and immediate. Programmer communication requires a decoder ring and considerable contextual knowledge.
