Aws::s3 Library

Sun, 02 Aug 2009 01:14:25 -0400

Hi,

On page 143 of the book, it is stated:
"You may experience problems using 0.4.0 of the AWS::S3 library..."

Would you tell us which version(s) don't have problems?

FYI: I am using aws-s3-0.6.2 and I emulated the usage of s3backup.rb from the bottom of page 142 and didn't experience anything disagreeable.

Regards,

Still On Page 21...

Thu, 02 Jul 2009 00:24:26 -0400

Hi folks,

I am still on page 21. I typed a few lines into a file named example.xml, which looks like:

1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b

2007-09-24T08:39:30.000Z

Then I typed a few lines like:

[tsakai]$ irb
irb(main):001:0> xml_text = File.new('example.xml','r').read
=> "\n\n \n 1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b3c4d5e6f1a2b\n jamesmurty\n \n \n \n oreilly-aws\n 2007-09-24T08:20:49.000Z\n \n \n my-bucket\n 2007-09-24T08:39:30.000Z\n \n \n\n"
irb(main):002:0> require 'rexml/document'
=> true
irb(main):003:0> xml_doc = REXML::Document.new(xml_text)
=> ...
irb(main):004:0>

What I don't understand is the response from my last line:
...

Can someone please tell me what this means?

Trouble With Aws.rb

Wed, 01 Jul 2009 19:36:45 -0400

Greetings,

I am trying to emulate what's on page 21 of the book, but I can't even get there. Maybe the code in AWS.rb is incompatible with the version of ruby I am using (ruby-1.9.1-p129)? Here's what the capture of my screen:

[tsakai@vixen ruby]$ irb
irb(main):001:0> require 'AWS'
SyntaxError: /home/tsakai/Notes/ec2/PAWS/PAWS_examples/ruby/AWS.rb:203: syntax error, unexpected ',', expecting tASSOC

Amazon Api - Pulling Member Order History

Wed, 24 Jun 2009 10:53:47 -0400

Just wondering on this, I can't find this being possible, and I just want to know if it is because I just am not searching for it correctly, or because they don't allow it.

I want to be able to pull in an Amazon customers order history (not just for "my" store(s), but, their entire order history). Basically having access to this information in the same way you can get access to a Google members information... you have them log into their account, and they grant your site API access.

Is this possible, or is their API basically only built around doing things with your own "store", not general member data (when permission is granted)?

Can't Get Past Example 2-2

Fri, 27 Mar 2009 16:50:20 -0400

I set up AWS.rb with Examples 2-1 and 2-2 and inputed the example then get the error message -

NoMethodError: undefined method 'encode_base64' for # from .... in 'generate_signature'

Any thoughts?

I'm running Python 2.5.2 with the latest version of lxml.

When I try to connect to AWS with the python PAWS code, I receive the following error. Any idea what I'm doing wrong? I have environment variables set for AWS_ACCESS_KEY and AWS_SECRET_KEY.

Thanks in advance for any assistance...

Are Ec2 Elastic Ip's And Availability Zones Covered

Wed, 09 Apr 2008 03:56:50 -0400

James

Thanks for this book. It looks excellent! Can't wait to get my hands on one.

I was wondering if the book covers the newly announced EC2 elastic IP's and availability zones, seeing that this enhances the nature of the EC2 offering quit substantially.

(The predicament of any "dead tree" book is that it can not always reflect all the latest advancements in the topics that it covers. Therefore, even if one could get some sort of online additional info to the book's content regarding elastic IP's, it would be very helpful.)

BTW, I am looking forward to getting my copy (and I am very happy that it uses Ruby)

Best regards
Willem

Sending Email From Ec2

Wed, 02 Apr 2008 06:41:05 -0400

Hi

Does this book discuss the problems with sending email successfully from an EC2 instance?

I am currently finding that EC2 is not a solid option since any emails generated by my sites or apps are either being marked as spam or just point blank refused.

I am yet to find a reliable solution for this!

Where are the chapters for SimpleDB, etc?

Thanks.

Having Trouble Finding The Book

Thu, 27 Mar 2008 20:57:30 -0400

I realize I could pay the full $50 and get an official O'Reilly copy but I'm not rich and Amazon is selling this thing for $32. But even though the release date was Tuesday, Amazon shows your book only available as a "pre-order." So that has me frustrated.

Also I don't see an option to buy the PDF anywhere on O'Reilly. Is that an option for your book?

Will any of the code you use in the book be available for d/l?

The O'Reilly previews suggest the book is very well written. Four services, That was a lot to take on. I'd be impressed with a scope of just one service. Do you plan on publishing more volumes, to accommodate mturk and all the rest?
