Bullet points

the url's are wrong. You need to remove the www from the start of the url i.e. http://www.ams.amazon.com should be http://ams.amazon.com

Note from the Author or Editor:
Remove the string "www." from six URLs included on page 5. There is one incorrect URL in the first line of the second paragraph, and five incorrect URLs in the dot-points of paragraph 4. For example, in the first dot point that ends with the link "http://www.aws.amazon.com/s3", the link should become "http://aws.amazon.com/s3".

Table 5-11

The value of shutdownState for "terminated" is incorrect in table 5-11. It reads: terminated (42): no longer running and should read: terminated (48): no longer running http://techbus.safaribooksonline.com/9780596515812/ec2-controlling-instances

Note from the Author or Editor:
Error is on page 180 of the printed book. The suggested text, "terminated (48): no longer running" is correct.

Last sentence

The sentence "What were the key goals that lead Amazon to build the services in the first place?" I believe should read "What were the key goals that led Amazon to build the services in the first place?" (lead -> led)

Approximately half way down

The sentence ending "by making its services accessible multiple data center locations" appears to be missing a word.

Note from the Author or Editor:
Change text from: "Amazon seeks to be resistant to traffic routing problems by making its services accessible multiple data center locations." To: "Amazon seeks to be resistant to traffic routing problems by making its services accessible from multiple data center locations." (added "from")

Paragraph directly after Example 2-2

The code in Example 2-2 relies on a custom method which is not defined until Example 2-10. The text states "Be sure to implement the encode_base64 method in Example 2-2 before you perform this test." but the reference should be to Example 2-10, not Example 2-10.

Note from the Author or Editor:
Published text: Be sure to implement the encode_base64 method in Example 2-2 before you perform this test. Corrected text (with altered example reference): Be sure to implement the encode_base64 method as defined in Example 2-10 before you perform this test.

In code sample

To allow unicode (UTF-8) text to be uploaded to a service's Query interface with a POST request, the request's Content-Type header must be explicitly set to support the UTF-8 charset: Content-Type: application/x-www-form-urlencoded; charset=utf-8 If the UTF-8 character set is not specified, upload of unicode text will fail with signature mismatch errors. By default, POST requests will not include the correct charset encoding value. This header has been added to the sample implementations in the book's downloadable code archive.

Near end of code example

The AWS#debug_response method example includes an integer argument (2) when printing out XML responses: REXML::Document.new(response.body).write($stdout, 2) Including this argument can cause errors in some versions of Ruby, the solution is to remove the integer argument like so: REXML::Document.new(response.body).write($stdout) This change has been made in the downloadable example code

1st paragraph

There is an extra "must" in the sentence which starts as: The original request message must must not be modified...

Note from the Author or Editor:
Remove one of the duplicated words "must" from a sentence in the middle of the paragraph 1, page 62. Change: "The original request message must must not be..." To: "The original request message must not be..."

It states: irb> obj[:headers]['content-type'] => "text/plain" Shouldn't this be: irb> obj_meta[:headers]['content-type'] => "text/plain"

Note from the Author or Editor:
Change the second-last line from the code block on page 85 from: irb> obj[:headers]['content-type'] To: irb> obj_meta[:headers]['content-type']

def statement of example 4-8

The def statement reads: def backup(bucket_name, path, force=false, options={}) To be consistent with what's in the file s3backup.rb, maybe it should be: def back_up(bucket_name, path, force=false, options={})

Note from the Author or Editor:
This submission is correct. In Example 4-8 on page 141, the name of the function definition should be "back_up", not "backup". Change the second line of the code example from: def backup(bucket_name, path, force=false, options={}) To: def back_up(bucket_name, path, force=false, options={})

In the second line of the first paragraph of section titled "Managing a Pool of MultiCommandService Instances" on page 343, change the text: "... application based on MutliCommandService components." To: "... application based on MultiCommandService components."
