Very good questions. I would like to add the following: How do I integrate a MongoDB application into an existing environment with loads of data already stored in (one or multiple) relational databases? Can I for example easily get to the existing customer data that the new MongoDB application also needs?

Anthony,
I understand I can get a C++0X thread library (like yours :-) to start using the new C++ multithreading features with my current compiler.
However, I suppose there are the other C++0X concurrency features for which I need a new version of the compiler. If so, what are those?

Best regards,

Hi Anthony,

It looks like a really interesting book but at www.manning.com I noticed that the "Early Access" to the book started in June 2008, with a scheduled publication of September 2011.
How came it is so long? (No critic of the author intended, if it brings me a better book I am all for it :-)

Best regards,

Hi,
There are other Android (programming) books around. Why should I buy Android in Action instead of some of the other Android books?
I guess my question is mainly directed to the authors but I appreciate any input.

As the title says: What are the strengths of Pentaho Data Integration compared to other ETL platforms (Open Source or not), for example Apatar or Talend?
I have not yet started to look into this but probably will in a couple of months so any pointers will be appreciated.

I've mostly seen DI discussed for use with Java. Is it as useful for other languages such as Ruby? (Some people think no, cf.

Hi Dhanji,
I downloaded the green paper "Dependency Injection: what’s all the hype?" from the books website and it says it is from
"Dependency Injection; With examples in Java, Ruby, and C#".
The book's subtitle on the website is "Design patterns using Spring and Guice". What happened to the Ruby and C# bits?

Hi,
As the subject says: what are the strenghts (and weaknesses :-) of "The Well-Grounded Rubyist" compared to "Programming Ruby 1.9: The Pragmatic Programmers' Guide" (Thomas/Fowler/Hunt).

According to http://highscalability.com/scaling-twitter-making-twitter-10000-percent-faster Ruby on Rails is not to blame for Twitter's performance problems.

Well, according to the publisher's web site this book it is not an introduction to Ruby. For that, go for example with the pickaxe book "Programming Ruby 1.9: The Pragmatic Programmers' Guide" by Dave Thomas, with Chad Fowler and Andy Hunt.
To start with Rails, a popular choice is "Agile Web Development with Rails" by Sam Ruby, Dave Thomas, David Heinemeier Hansson, et al (which contains a short introduction to Ruby)
(No, I don't have any connection to "The Pragmatic Programmers" except as a satisfied customer)

Hi,
What are the strenghts of this book compared to "Enterprise Recipes with Ruby and Rails" by Maik Schmidt which seems to cover similar issues.
