Great article. Only I would use an unless statement, rather than if and a boolean negation operator. more ruby like and more readable IMHO.

i.e.,

unless mail.to.nil?
BEANSTALK = Beanstalk::Pool.new(['127.0.0.1:11300'])
…
end

Thanks, Jason, it really works.

There's a Rack coding contest starting now if you want to enter. It's at http://www.coderack.org

Some great prizes and it promises to be a lot of fun.

I thought the mail_receiver.rb file will be lauched for each email received and then will stick the email in the queue. I realize that it does not do much but it is creating a ruby process and letting it exit for each email. Is that a high overhead on a system?

Doing it this way specifically avoids spinning up a new process each time as you're running it as a daemon. You wind up having one process running constantly that processes each one as they come in.

Some of the other information that i have read talks about how doing it this way means that a new ruby process is started and killed for each email that comes into the system. According to the math above that would mean that you have about 833 processes being created/deleted per minute on the server. Are you guys having issues with that model?

It seems the polling model avoids this but not sure if the tradeoff for less processes is worth the loss in responsiveness and can we just poll more often to get rid of the issue? Like once ever minute?

You can also use the constant RAILS_DEFAULT_LOGGER to get the same thing.
In gems/rails-2.3.2/lib/initializer.rb:
=====================
module Rails
def logger
if defined?(RAILS_DEFAULT_LOGGER)
RAILS_DEFAULT_LOGGER
else
nil
end
end
end
=================
That way you can easily set the constant (ex: in testing) without having to stub and mock Rails and #logger (in case you don't have access to them for some reason...).

But in any case, very good tip! I always used the constant, glad to know there's another way.

Nice tip... Thx....

Will it work in the rake tasks? I hope it should.....

It helped me*. I'd even do a commercial where I give one of those (paid) testimonials about it. "Jason Seifer's Rails logger did the trick for me!" Something like that. We'd sell millions.

*I don't know what any of this means :(

Well, you got me on this one. I came in on a rack rail keyword search. I can say I learned something new reading this. I am pretty good at advising people on the correct server rack to use with there hardware. If I can be of help to anyone, let me know.

Every thing works great. I get the native resolution on my 30" Cinema HD.

Thanks.

Are you sure you have the dual link dvi adapter? What kind of message does it give you?

Re: Mini DisplayPort to Dual Link DVI Adapter Fix (Temporary)

michael180 — Tue, 14 Jul 2009 18:15:36 -0000

My works okay, but I can't get my 30" Cinema Display to display in it's native resolution.

Any suggestions?

I returned my adapter to Apple, the replacement doesn't have the same problem...

how do you guys deal with stripping the quoted original message out of the reply?
in one of my apps users can reply to message notifications by e-mail and the mail processor parses out their comments and posts them in the thread. we've taken to writing a new regexp every time we come across a new e-mail client and falling back on cutting everything after something like "=== Post your comments above this line ===". any better ideas?

Piping emails to a ruby process can present some scaling issues. Each email is basically another ruby process that loads rubygems, tmail, mms2r, etc. It's probably better to just have postfix dump emails to a maildir and have tmail read them in a little ruby daemon: http://tmail.rubyforge.org/rdoc/classes/TMail/M... . I handled all of our email processing fine with ruby pipes for awhile. But when I moved to our current host, they were quick to suggest using a maildir.

I didn't know about mms2r, but I'll take a look at that. I think I parse the mail parts manually with tmail right now, blah :)

hey jason - also check out Astrotrain on github. it receives e-mail and issues xmpp or http in response. blatant plug for my employer but it's what enables Tender to turn e-mails into support discussions. like how Tripit turns e-mails into itineraries automagically.

Jason,

Thank you very much. I really needed the local documentation and find all the steps ready here :)
