FOLLOW CAPTAIN TWEET ON Twitter

Aymeric has helped me steadily progress with the code for Captain Tweet. And I'm starting to understand dictionaries and strings better.

06/21 -- Copied code and log to server. Runs in screen.
How-to: 1)ssh into server 2)"screen" 3) "ctrl a" "s" for new window 4) python captain_tweet.py 5)"ctrl a" "d" out of screen 6)"ctrl d" out of server

07/02 -- script stopped after error message from twitter, no duplicate messages allowed within certain time frame. Possible solution: "Whatever code you have that uses Twitter's API needs to handle errors and exceptions --- they happen too often to ignore".............. so I have to build in a line that if there is an error, the script should skip it and keep running.

07/04 -- Evo showed me how to fix the bump. Built in a "try" line. Over the following week, I adjusted the log so messages within 24hrs are no longer exactly the same. Added spaces between words which seems to do the trick.

08/04 -- Captain Tweet now has 28 followers, about half of which are ship crew and shipping journals.

09/12 -- Laura Dekker, a 16-year old Dutch girl who's sailing around the world, solo, is now also following Capt Tweet! And NL010 published a line on the project in their September issue.

Some important things to note:

• I changed the original dates to fit the dates of the show. Ideally I'd have this start on December 16, which is the first entry of the original log. I've changed it to June through November. So... in case you're wondering, that's why it's snowing in July.
• The log used is Captain Turner's log, transcribed by Sue Mackay, of Cardiff.
• The HMS Weymouth, the ship that's tweeted from, was used to transport over 450 settlers, including children, from Portsmouth, United Kingdom, to Algoa Bay (Port Elizabeth), South Africa.
• This project is based on movements of migration, exploring the seas, claiming new land, and colonialism, which is only expressed indirectly. I felt I had to focus on advancing my programming skills, while keeping an eye on the concept. I think this can be pushed further but not in this project necessarily.

TO DO:

• PRESENTATION IN SHOW! Display twitter feed on twitter url? Make new html design for HMS Weymouth w/twitter feed embedded? What communicates the simple idea of logging from 1819 into 2011 best?
• figure out kiosk mode & browser refresh
• make twitter url "home" on exhibit computer
• update time in log to standardized 06:00 etc hours that Python can read
• create new twitter account for the captain
• make friends for the captain
• put code and log on the server, run it from there
• add to code: #check for date continuously and time, when there's a match, push message from log to captain's tweet feed
