Over the years, we’ve had a lot of people submit jokes for LOL. Since we’ve recently upgraded the site to allow user submissions, we thought it would be nice to let them know they can now add their own jokes (Truth be told, we were slow adding them).
I’m not going to go into great detail, but I thought I’d post a mini howto. Note: I’m not supporting this code, but you are free to use it
Firstly, Ruby 1.8’s POP3 implementation doesn’t support SSL. stunnel provides encrypted channels for software that doesn’t understand SSL. I run cygwin on my Windows box to get access to essential tools. Note: Configuring cygwin and installing it is beyond the scope of this entry, so ask Google for help.
A quick search for gmail and stunnel allowed me to cobble together the following configuration file called gmail-tunnel.txt
client = yes
debug = debug
foreground = yes
[pop3s]
accept = 127.0.0.1:42
connect = pop.gmail.com:995
Open up a command window and issue this command to start the tunnel:
C>stunnel gmail-tunnel.txt
Save the following code in rpopget.rb and then execute it from another command window while the tunnel is active. It will write a file called address.csv that lists each address and the number of times that person sent mail.
#!/usr/bin/ruby
require 'net/pop'
HOST = 'localhost'
USER = 'YOURACCOUT@gmail.com'
PASS = 'YOURPASSWORD'
$addr = {}
def add_address(a)
$addr[a] = $addr[a].nil? ? 1 : $addr[a] + 1
end
Net::POP3.start(HOST, 42 , USER, PASS) do |pop|
if pop.mails.empty?
puts 'No mail'
else
pop.mails.each do |email|
$stderr.printf(".")
lines = email.header.split("rn")
lines.each do |l|
if l =~ /^From:/
if l =~ /^.*/
add_address($1)
elsif l =~ /^From: (.*@.*)[ ]*/
add_address($1)
end
end
end
end
end
end
open("address.csv", "w") do |f|
f.puts "Address,Count"
$addr.each_pair do |a, c|
f.puts "#{a},#{c}"
end
end
A co-worker dropped in and picked up one of my
