I’ve made some improvements to Alphabet Clock, most notably the inclusion of dates and developer libraries. Read the full story on Alphabet Clock’s blog.

cron is a daemon that will execute commands at a scheduled date and time. You use the
crontab command (short for cron table) to set up
cron to execute commands at regular intervals.
If you haven’t used
cron before, I recommend reading this excellent introduction to cron and crontab and looking at this example crontab file. You should have at least a basic understanding of
crontab before proceeding.
s3sync comes with two utilities: s3sync.rb, which can backup a directory to S3 rsync-style, and s3cmd.rb, which gives you a command-line interface to S3. We’re actually not going to use s3sync.rb to backup our files (in the next blog post I’ll show you how to use astrails-safe instead). However, we will be using the s3cmd.rb utility now in order to interact with S3 from the command line.
