Java Web Services: Up and Running

This the second edition of Java Web Services: Up & Running, this means updated content from previous one with .

 It's all about RESTful services nowadays and that's the main goal of this edition.

So you will be reading about JSON, JAXB, SOAP, annotations with Jersey to fastrack development and many other features.

To complete the world of web APIs, the master language is XML so be prepared to see many elements and attributes around ;-)

This is for the fun and descriptive part.

The less funny part but respectful and required is about Security, adn SSL protocol (httpS://...).

I would recommend this easy-to-read and compact useful descriptive guide that will make you understand the underground of the web services with Java using technology.

Building Hybrid Android Apps with Java and JavaScript

This the first edition of what is starting to be most important web development nowadays.

"Building Hybrid Android Apps with Java and JavaScript" is a book from O'Reilly and was given to me free in exchange of this review. You can find it here:  http://shop.oreilly.com/product/0636920028994.do

I wanted to read about the subject because i will need to do a project in the near future and have to decide whether or not the app should be

Native apps, built for a specific platform with the platform SDK (which is isn´t totally free).
Mobile Web apps are server-side apps, built with any server-side technology (PHP, Node.js, ASP.NET) that render HTML that has been styled so that it renders well on a device form factor. This solution is a steep harder developpment curve than the previous one.
And the Hybrid apps, like native apps, run on the device, and are written with web technologies (HTML5, CSS and JavaScript). A web-to-native abstraction layer enables access to device capabilities that are not accessible in Mobile Web applications, such as the accelerometer, camera and local storage.
Thinking of JQuery mobile and other libraries that really embed the app in the browser and taking full advantage of html5 to do stuff such as local storage for off-line usage! And no need to know Java, Objective-C and other SDK language related to native app. THis hybrid apps will be written -almost- once and will work in any device.

The book "Building Hybrid Android Apps with Java and JavaScript"gives a very general but accurate and detailed view of the concept, tools and steps you need to follow to successfully create your hybrid app.

The book focuses on developping android hybrid app using Eclipse IDE. All the Android tools (debugger, virtual machine,etc.) are described and you can start from scratch without knowing anything about this area in particular of software development and yet creating you hybrid app. A large part of the book shows how is the interaction -the glue!- between the mobile browser WebKit and the call from/to java to JavaScript and vice-verso.

The book mentioned also a lightweight web application framework developed for building hybrid applications that can be found in github site.

It even shows you how to publish it in android market, sorry, Google Play! And Amazon app store!

I would definitively recommend it but i would say that this is really a starting point. A lot of code needs to be done and tested for a complete app.

Data without visualization is useless

The book Interactive Data Visualization
for the Web from O'Reilly Scott Murray is very good and helpful guide to visualize your data using D3.js.
In particular, it transverse the usage of charts and histograms through severals examples.
D3.js is a javascript charting library which use SVG to produce nice and colorful plots.

If you are in the Bigdata business or just want to make talk your data, you should read this book.

Testable Javascript

This post about the book "Testable JavaScript" from O'Reilly editor which i got as an exchange from their blogger reviewer program.
I cannot start the analysis of the book without saying that is really more about testing and software engineering good rules to get a nice readable, maintainable, efficient, clear, reusable and high quality code.

The language is really a second layer. What you will learn the first chapters is about how you could (SHOULD!) improve your code and the author, Mark Ethan Trostler, is really clear on showing the reader how you reach the goal with the help of several tools specifically for JavaScript! That's the JavaScript part which i was interested in as i come from the software development engineering world using Java as main language so i wanted to get some tips about what to use in the JavaScript case.

Traversing the client side framework PhantomJS and the server side Jasmine, the author shape the testing world in JavaScript in a good, concise and clear sentences with the code samples as proof of concept.

Then the following chapters are about code coverage and integration that can be done also with Selenium which i use in my current work to test jsps code and i knew that you can also test JavaScript code.
Selenium is great and powerful API client/server testing environment! - I use it even to test the JSP compilation very easily without any deployment setting or embedded jetty! -

Debugging javascript is a chapter on tis own and covered what you probably expect already that you can use add-on in Mozilla or Chrome to debug you JavaScript code.

The last part is about the favorite part of QA people which is the automation and continuous integration testing. Jenkins and Hudson are both mentioned of course! Personally i use Hudson but they are really similar ;-)

Great book for better coding, better life! It really accomplish the goal i was expecting!

Getting Started with Raspberry Pi

I was expecting much more from this book. I bought my raspberrypi and was expecting the book to solve problems when starting and booting.
Of course, the book only shows first steps considering everythng going ok but i have problems with the network, the keyboard, the os, etc. I've found information in forum pages at raspberrypi.org but not in the book.
One chapter is about Linux administration, another on python. The arduino and GPIO part is ok but not detailed though.
The book is really a starting point and don't expect to find a reference for solving problems.

The book can be bought at http://shop.oreilly.com/product/0636920023371.do

Won't recommend it.

Canon EOS 5D Mark III: The Guide to Understanding and Using Your Camera

This book is a step-by-step explanations of the features and capabilities of the 5D Mark III, the most desired newest camera of Canon after the world famous mark ii. Is more than a guide because it explores step-by-step setting adjustments, color illustrations and details for each option. Nevertheless, i would recommend the guide only if you have the camera unless you are already familiar to Canon 5D series. This is not a book to decide whether or not you would buy it, it is a guide to use all of its great potentials! I was expecting more details of photography tips and methodology but the book title is clear, is all about the device. The book can be bought here: http://shop.oreilly.com/product/9781937538156.do Disclaimer: This book was given in exchange of O'reilly reviewer program.
