Hi,

What's the audience of the book then? Is the book for architects or CTOs?

Jacek

Hi,

What are the streaming frameworks covered in "Streaming Data: Understanding the real-time pipeline" book and what are the others not covered in the book but worth watching closely (as they offer quite interesting features)?

Hi,

I'm very new to RabbitMQ, but am willing to learn a little about the project. I'd love knowing why it works the way it does (not only how to get it up and running). Should I start with "in Action" before "in Depth"? What sets apart the book "RabbitMQ in Depth" from "RabbitMQ in Action"? Is there any comparison to other message passing systems? Since I'm Scala persona, how much can I learn about using RabbitMQ as a Scala developer? Is there any comparison to Akka?

Hi,

Wow! I've got selected. Thanks a lot.

Thanks for being able to dive in to graph databases with the book. I seem to be sold to the other graph databases to use in the upcoming commercial project with gdbs like TitanDB, OrientDB or even ArangoDB, but don't mind reading what I'm going to miss in Neo4j.

Jacek

Hi,

As a follow-up to the question, I wonder what project would be the reference implementation of the concepts in neo4j. I'd like to have a step-by-step project where just a neo4j newbie like me would be able to see the features in action. Is there such a project available?

Jacek

Hi,

I'm wondering whether or not neo4j requires a NoSQL db to proper work and if not, would there be any benefits of running it atop Cassandra for time series? Does the combination make any sense?

Jacek

Hi,

I'm new to neo4j, too, but found the answers in What kind of data fits Neo4j best (or worst)? and Does Neo4j worth learning? worth exploring before expecting another (which I hope will ultimately come to expand on the other two).

Jacek

Hi,

What would I need the Enterprise edition for?

In http://neo4j.com/editions/ I found Enterprise Lock Manager, Clustering and Advanced Monitoring a bit troubling to imagine when I'd need it. Does the book explain the whys/use cases for the Enterprise edition?

Jacek

Hi,

Does the book show examples of using neo4j with the other languages, esp. Scala?

Jacek

Hi,

Is the book about how neo4j stacks up against other graph databases like orientdb, arangodb, titandb and such? Would the book guide me how to pick a proper graph database for my use case?

I'm currently evaluating graph databases for a project to store CMDB data (http://en.wikipedia.org/wiki/Configuration_management_database) and without much thoughts crossed out neo4j because of its price (too high) and features (too little) comparing to the contenders.

Jacek

Hi,

What are the examples in the book? Are they more short examples or complete applications?

Hi John,

I've been asking about the contents of the book before as I couldn't find it on Amazon and alike.

Do you present the value proposition of Clojure and why Clojure or functional programming in general in this book? People keep asking me these questions many times and usually fall short to bring valid examples (without overwhelming them with the concepts of immutability, composition or such).

How far does this book go to explain why's rather than how's?

Hi,

It's not that bad. You've got more time to learn Clojure in your own spare time :-)

Seriuosly, you should give Clojure a harder try since it may bring more fun that Java. Although Java's important - learning Java API helps a lot in Clojure as it leverages lots of the APIs - Clojure might influence your thinking in a pleasant way.

I fully agree that picking the right language for a start is not an easy task now when Clojure, Scala and Java (not to mention Ruby, Python or F#) are available and they bring their own fun. Good luck!

Hi Norman,

That exactly reflects my sentiments - it's quite interesting and amusing to see how one could develop a decent UI application in Clojure (or any other functional language) as the process is more dynamic (REPL) as well as challenging where mutable state is wrapped by a thin layer atop a immutable/pure one. It'd be a highly recommended exercise for anyone who'd like to enter the functional programming scene - it's especially helpful to see someone who's good at FP doing it (I think I've seen a video on youtube or vimeo).

David Starr wrote:What does it mean to be a Functional Language?

Hi David,

As the name implies a functional language is about writing applications out of functions. A function composition is one of the main themes in functional programming languages. There are other features of functional languages that are usually offered by them (immutable data structures, concurrency abstractions, dynamic typing), but the building block - a function - is what drives development in FP.
