Rails - Jan 2009 - New cheat sheet: Jump Start Credit Card Processing in Ruby

Hey guys... it''s me ;)

I''ve come out of a long cheat sheet-free period!

I want to share with you my new, really massive "cheat sheet" on
credit
card processing:

* the process,
* how it works,
* what you need to get the right accounts, and of course,
* how to get started with ActiveMerchant.

Download it here: http://jumpstartcc.com/

Aaaand... Thomas Fuchs contributed a spiffy JavaScript for detecting CC
types and validating against the Luhn10 algorithm.

This little guide is based on what we learned developing our new time
tracking service, freckle: http://letsfreckle.com. Even with the help of
some excellent existing libraries, the whole process was brutal!

I hate being brutalized! And there is crap all for resouces out there on
this topic, so I figured I''d share the knowledge. :)

Let me know what you think!

Amy

Thank you Amy - always a (brutal) and mysterious process.

Hi Amy,
Without having looked at your cheat sheet yet, nor at any code that might be
out there for validating credit card numbers, can I put in a request to
eliminate one of my (many, I''m sure) pet peeves...

Did/can you address the issue of allowing the end user to put spaces in
credit card numbers?

I find it much easier to enter 4 digits at a time, as they are printed on my
credit card, separated by spaces and get annoyed at sites that require that
I enter all 16 digits in one swell foop.

Whew!  Boy am I glad I got that off my chest!

Oh, great idea. I hate that too! I didn''t think of it when I was 
writing, but I will definitely add it, one way or another.

Perhaps we can add it to the JavaScript as a way of encouraging good 
behavior.
> Whew!  Boy am I glad I got that off my chest!
I know how that feels!

Anybody else with ideas, suggestions, or questions... let ''er rip!

Oh, and if it helped you, I wouldn''t mind hearing that either ;)

Cheers,

Amy

What did you use to type the mini-book? It looks fantastic and is much 
easier to read than a boring manual! Is it LateX? OpenOffice? M$ Word? 
Other.

Where did you get all these cool little images? Do you crate them 
yourself or do you have a pool of images in which you can pick?


Best regards,

Ok, it says a lot when I find myself chuckling at the sheer cuteness
of a technical guide.

This is fantastic, and just in the nick of time.

What other guides have you guys written?

Hi,
very nice ! (though mostly US-centric ;-) )
Another good source, if you want to use Paypal specifically, are Ryan
Bates''s last 3 RailsCasts.
Rgds,

Elise

Glad it''s helpful :) We''ll be blogging more about this stuff
on our
site: http://letsfreckle.com/blog.
> What other guides have you guys written?
None like this, yet.

We''re working on a ~60-page ebook on JavaScript performance and
scaling,
specifically, that I hope to publish in February, for $29 (including 
some awesome tools we''ll also OSS later).

Sign up for the email list on jumpstartcc.com and I''ll send you an
early
adopter discount ;)

Matt, I don''t know if you''re familiar with my older cheat
sheets.
They''re not this big, but clearly I''ve been working up to it:

http://www.slash7.com/cheats/activerecord_cheatsheet.pdf
http://www.slash7.com/cheats/form_helpers.pdf
http://www.slash7.com/cheats/scriptaculous_fx1.pdf
http://www.slash7.com/articles/2006/10/8/rjs-demistified-with-pretty-colors

For the record, I do these up in Omnigraffle, although I''m about to 
ditch that in favor of either Keynote (unlikely) or InDesign (likely) 
for any future 10-pagers. I am an OG ninja, though, so I don''t think
I''d
recommend the tool to anyone else.
> Where did you get all these cool little images? Do you crate them yourself

The illustrations are from istockphoto.com. I probably dropped about 
$100-$120 on stock art for this baby. I do not like to do a half-assed 
job.

Thanks for all the feedback :D

Amy, thanks for those links, but looking at one also reminded me --

Major props for creating the CC guide with an aspect ratio that makes
sense for reading online.  :-)

One of the main reasons I generally despise PDF is having to scroll
up and down to read something formatted for an vertically oriented
8.5x11"/A4 printed page rather than a typical wider-than-tall screen.

So thank you, thank you, thank you!
