Jonathan Feinberg has made a neat hack: Haiku Finder. It uses NLTK to parse English text, looking for sentences that happen to fit the syllabic pattern required of haikus. It seems to work really well. I ran it on my longer text pieces, and it found these:

These are personal
    tools, meaning they do just what
I want them to do.

People who visit
    the page in their browser will
see the new entry.

But this powerful
    feature of C++ is missing
in those languages.

I know this sounds like
    coddling, or bending over
backward, and it is.

And maybe you don't
    want to put effort into
improving your log.

It sounds simple, but
    there are right ways and wrong ways
to go about it.

Ask them to tell you
    what they're thinking as they look
for the solution.

If you get it wrong,
    the object will be freed out
from under you: crash!

This is a macro
    that creates the initial
fields in the structure.

It seemed like I was
    buried in that dark harsh towel
cyclone for ages.

Note that it did a great job, but didn't know that "C++" is a three-syllable word, not one syllable.

If you want to try this, you'll have to install NLTK, which is a large package. It requires the punkt dataset, so you have to install that from the NLTK page after the code is installed. The whole process is automated, but perhaps more than you expected, so be forewarned.

You may remember Feinberg as the creator of Wordle, so I expect we'll see more inspired language-related hacks from him...
