Hi there
Some of you would remember Railscast script, so I coded a new version using SQLite3.
The new version is this one and the empty database is that one. 
Enjoy it
P.S. Remember to rename the empty database file from EmptyRailsCastDownloader.db to RailsCastDownloader.db.
Thanks for the useful info. It’s so interesting
This might be helpful for others, when the script running, it throws up the error like
Adding downloaded episode to restart file.
railscastdownloader.rb:111:in `insert_downloaded_episode_to_restart_db’: wrong number of arguments (1 for 2) (ArgumentError)
from railscastdownloader.rb:111:in `download_casts’
from railscastdownloader.rb:91:in `each’
from railscastdownloader.rb:91:in `download_casts’
from railscastdownloader.rb:171
How to Fix,
go to line 137,
137 def insert_downloaded_episode_to_restart_db(id, downloaded_episode_name)
just take the id out
