Happy PiDay with millisecond precision

Tweet on PiDay with millisecond precision

equation

Four time the sum of minus one at the power of n over two times n plus 1 for n going from zero to infinite

This programs has been designed to send an Happy PiDay Tweet on 3/14/15 at 9:26:53.590 UTC with millisecond precision as described here.

Program Usage

Requirements

The code is written in python2 and has been used on Python 2.7.3. I cannot guarantee that it works on other version of Python. The programs requirements are only Tweepy version 3.0 or better and Requests.

For the data analysis part also SciKit Learn is required.

sp80.py

The main program is in sp80.py:

python sp80.py -h
usage: sp80.py [-h] [-a ACCOUNT] [-m MESSAGE] (-r | -c) [-t TARGET]
               [calibration]

Secret Project 80/PI. Tweet on "four time the sum of minus one at the power of
n over two times n plus 1 for n going from zero to infinite"

positional arguments:
  calibration           Database with the calibration data

optional arguments:
  -h, --help            show this help message and exit
  -a ACCOUNT, --account ACCOUNT
                        Index in the account list to be used to tweet
  -m MESSAGE, --message MESSAGE
                        Index in the message_set list to be used for the tweets
  -r, --run             Do the actual tweet
  -c, --calibrate       Calibrate the Twitter
  -t TARGET, --target TARGET
                        Time to tweet

So python sp80.py -c will launch the program in calibration mode (send a sequence of 4 tweets immediately deleted to get calibration data) and will store the info in the file calibration.db. Using python sp80.py -r will run the program in real mode. -a and -m select the twitter account and the message set to use, if ignored use the default index = 0. -t override the target time. The time should be in RFC 2822 format.

Before running the program check the file settings.py.

settings.py

The file settings.py is the main source of configuration information for sp80.py. It contains a single dict with the following keys:

  • accounts: a list of dicts with the accounts to be used to send the tweets
  • apis a list of dicts with api keys for the Twitter app to be used to send the tweets
  • target_time a dict with the target time at which the tweet must be sent
  • message_set a list of dicts with the messages to be used. Each dict should contains the following keys:
    • target The tweet to be sent on target time
    • test The tweet sent last in the test sequence. It is used instead of target during calibration
    • ramp_up_n Sequence of tweets with n going from 0 to 9 (could be less) used during the warming up phase both in calibration and run (in run, if succesfull, are not deleted, so keep them meaningful!)
