Mastering Eclipse Plug-in Development
Mastering Eclipse Plug-in Development
Price: CDN$ 16.49

4.0 out of 5 stars powerful tools, Dec 7 2014
Hmm. The book came out in August 2014. Strange that no reviews have been posted by now (Dec 2014), so I will try to remedy the situation.

Eclipse is perhaps the most common development environment for java programming. Blewitt shows the latest developments in its support for adding plug-ins. A good aspect of the book is that it jumps right in. You are expected to be already using Eclipse and hopefully have written some prior plug-ins.

Chapter 2 has a long discussion about how the classpath is used. As a practical matter, complexity and bugs can arise from problems with the elements (jar files) listed in the classpath. This is not restricted to programming with Eclipse. But the chapter delves into the details of, for example, the loading of all extensions via the classpath. To this ends, you might also check out chapter 6, which is a companion description of class loaders. Historically, this was the crucial idea that drove the very successful use of java inside enterprise computing on the Internet in the dot com years. You can now see here what the latest features of the class loader can do for your code.

The text also goes into OSGi services and runtime. For dynamically hooking up your executable to existing services.

Another useful feature is the Gogo shell and a console view, where the latter comes with Eclipse. Likely, you have run the console to see output from your programs. But the text shows how other consoles can be invoked, with various advantages for each.

Throughout the book are many code snippets and examples of running programs from a console or terminal window. Useful guidance.

Oracle Solaris 11 Advanced Administration Cookbook
Oracle Solaris 11 Advanced Administration Cookbook
Price: CDN$ 25.56

4.0 out of 5 stars focuses on unique aspects, Nov. 29 2014
Borges offers you a hefty and comprehensive explanation of Solaris 11 administration. He has considerable experience in the matter, having worked on Solaris 7 in 2001. He offers the reassurance that since Oracle acquired Sun Microsystems, it has put considerable financial support into maintaining and extending Solaris. The book is offered as evidence.

One important feature is ZFS - a 128 bit file system that supports transactions. What Oracle has done, and not surprisingly, is embed its flagship database (which is currently Oracle 11g) all the way down into the silicon. By owning both the operating system and the database, and optimising the combination. Thus what distinguishes 11g from its competitors is the fast transaction rate. So if your firm does many transactions, Solaris 11 and the relevant sections of this book may be the most compelling reads.

Another topic is Internet Protocol Multipathing, for fault tolerant network interfacing. It's a very mature product that the text explains in detail, for more robust server sites.

Indeed, a strength of the book is how it does not waste time explaining common and low level sysadmin commands, that are largely unchanged over 25 years from earlier Unixes. Those commands are a commodity amongst the remaining Unixes of today and linux. The book focuses on the unique aspects of Solaris.

Mathematica Data Visualization
Mathematica Data Visualization
Price: CDN$ 9.99

4.0 out of 5 stars rapid graphing, Nov. 29 2014
This book differs somewhat from most Packt offerings, which are often about software packages recently released. Mathematica is venerable; the first version hails from the mid 80s. Predates the Web!

By now, Mathematica is very complex, with many routines for data analysis. The emphasis by Saquib is on how to see your results. As an aside, all the images in the book are in black and white, to save printing costs. But Saquib and the publisher have made available colour versions on the Web. Serious readers should look those up, for colour adds a useful extra dimensionality or depth to how you can understand data.

The book glides quickly over 2d graphs. Quite mundane and frankly such stuff is really a simple commodity these days in visualisation. The value of the discussion is in 3d plotting and in picking 2d images from those higher dimensional scenes. Like the isocontour and isosurface plots. You should experiment extensively with these. Mathematica has gone to some length to make these as easy to generate as possible. A major point of the text is how to do these easily and thus often. There is an interactive loop, where by being able to make these graphs rapidly, you can experiment with peering into your large data set many times. Hopefully, insight will follow.

There is also an interesting section on text visualisation. Where you have amassed a corpus of text documents and can then study what the documents are about. This reflects the data often found from social network feeds. The examples are rudimentary but still worth studying as a basis for your work.

Learning Unity Physics
Learning Unity Physics
Price: CDN$ 9.99

4.0 out of 5 stars rigid body collisions, Nov. 29 2014
I am not sure if the "Rigidbody" is a term already used in Unity or it was just coined by the author. As a physicist, I have to say that none of the texts I used ever had that term. It is just conventionally 'rigid body'. But aside from this, the text is quite straightforward to understand. It plays [pun intended] to the desire of many game programmers to inject realistic physical interactions into their scenarios. And yes, interactions between rigid bodies are indeed the most common. Partly due to the relative simplicity of modelling. Because the alternative is to model inelastic bodies when colliding. You can do this, but it is much harder and more computationally intense. So perhaps the first choice you have in your game is to decide whether to solely use rigid bodies or not. As a pragmatic matter, you should say yes.

Unity allows for 2d or 3d games. Good. Many of the book's examples are 3d, for greater realism. And within the games, collisions are typical. Unity comes prebuilt with the means of handling 3 types - box, sphere and capsule. In case you are wondering, capsule collisions are mostly meant for encapsulating a humanoid character.

Most of the text's examples are instructions and screen shots about using the Unity GUI to build parts of a game. There is very little in the way of actual code scripting snippets. The engine makes these. But the text is meant as a first text on its subject. A sequel to this book might discuss more at the explicit scripting level.

PhoneGap and AngularJS for Cross-platform Development

The virtues of PhoneGap are well known to mobile developers. You in principle only need write one version of your program, and PhoneGap will make iPhone and Android binaries out of it, linking to the appropriate libraries in both operating systems. But the author of this book explains AngularJS, which attempts to aid one major step further. You can see how Angular [I'm just going to drop the JS as tedious and most people I know who use Angular just call it that] is in essence another refactoring. Where APIs are provided within it for you to get at sensor data emanating from the mobile device, which of course is typically a cellphone.

The text also acknowledges Facebook's importance. Several examples discuss how to use Angular to simplify a Facebook login. Apparently, many users are already logging into Facebook while travelling.

Another importance case covered is using Angular to make code that uses RESTful operators. REST has become popular for simplifying the logic of accessing a web server in a stateless manner, instead of stateful. Well, the book has a simple example of how to write an Angular app for this.

It should be said that all the book's examples are rather cursory. Deliberate, so that you can scan the book rapidly. However if you want more detailed examples, the best approach is of course to write them yourself, using the text as a launching pad.

Wireshark Essentials
Wireshark Essentials
Price: CDN$ 9.99

4.0 out of 5 stars many options, Nov. 23 2014
I was a sysadmin and programmer who had to write low level C code to parse Internet packets. Very tedious and error inducing to understand all the levels of the TCP/IP protocol stack. In huge contrast is the package known as Wireshark. The 'wire' of course refers to the cable along which the packets are traversing.

The examples in the text largely use IPv4 instead of IPv6. v4 is still the most common addressing on the Internet. But note that Wireshark can certainly handle decoding v6 packets. The use of v4 in the text also has the merit of somewhat simpler notation. All the concepts discussed using v4 carry over to v6. Chapter 5 is where the discussion explicitly involves v6.

Wireshark has many handy parameters, reflecting a considerable development history. By now, it is quite refined. For example, when capturing and storing data to your disk, one option is a ring buffer. In other words, a fixed maximum length is defined for the data. When this is reached, the program goes in a loop [ring]. It overwrites the earliest data. A trivial thing to code as you can appreciate. But it prevents your disk from getting filled. It lets you typically set a trigger on some anomalous event. When activated, you then only look back for some relatively shorter time at preceding events, to try to find correlations.

Restful Java Patterns and Best Practices

4.0 out of 5 stars deprecates SOAP, Nov. 22 2014
Remember the last 15 years or so, when SOAP and WSDL came of age? You could and indeed may have used them to make websites of considerable complexity. But that complexity was the rub. Sometimes hard to write and later maintain. After all, check out some texts from then, that had XML encoded queries. Extremely verbose and brittle. Sure, it was XML and you could read it, after a fashion. But awkward.

This current book explains an alternative that is now very popular. The REST approach emphasises a true stateless interaction, where every client browser request has the full details. This frees up the server logic from having to maintain a record of information that might have been needed from earlier requests. Allowing for much easier coding on the server. Plus of course the possibility that the server now handle a greater load of such requests.

Those of you mathematically inclined will see this as analogous to idempotent operators.

The text is brief and in some ways this is due to the relative simplicity of the REST approach. Something you should appreciate above the lower level details on the pages. The description is quite complete. You also are guided into the other key feature of REST - using http verbs like GET, HEAD and PUT. The sheer clarity of this contrasts nicely with SOAP.

Cocos2d-x Game Development Essentials
Cocos2d-x Game Development Essentials
Price: CDN$ 9.99

4.0 out of 5 stars a quickie, Oct. 12 2014
Well, the book focuses on writing mobile games in C++, which is correct for the majority of games. So if you are starting out in game development, you are making a good choice professionally. Another advantage touted is the free open source nature of Cocos2d-x. However, note that you can of course write games that you own, in it.

Another advantage is the cross platform nature. For mobile games, this boils down to 2 main choices – iOS and Android. Most of the book's examples are for iOS. The game examples are brief, as indeed is the entire book.

Of the graphics, they tend to be simple given that the screen will be on a cellphone. Sprites are quickly explained, but this is a straightforward concept to grasp. The text shows how actions can be done to these sprites, like moving or fading or rotating them. You can have fun varying your code snippets to rapidly see how code changes propagate into visible changes on your mobile screen simulator.

The touch ability of a mobile screen is used in a chapter. Undoubtedly some of you [most?] will find a use for touch in your games. The chapter describes single and multi-touch effects. Also easy to code.

Play Framework Essentials

4.0 out of 5 stars make more interactive web pages, Oct. 12 2014
Making a web application can be complex and Play tries to help simplify the process. Richard-Foy starts with the basics of explaining the architecture of such an application – from the client browser to the web servers. Play offers the choice of java or Scala for coding. Java is much better known to many.

Like Ruby on Rails and other languages, there is a standard projects layout for the files. So you need to know for Play that source files go under app/ and test files in test/, for example. As a practical matter, if you get deep into a project, you may or rather will need to manually go into such directories and add or remove files for debugging or other development needs.

The book also has good advice on testing whatever web application you make. One such is to use Selenium WebDriver which lets you write automated tests for a browser. Perhaps you have wondered about how nice this would be, well it has been done. You can now define numerous unit tests for your user interface and just run these all from one simple command.

A more advanced topic is how to handle long running requests from the browser. One solution is to use Ajax, while another is to use WebSockets. Either gives you greater interactivity from the user standpoint while she is running her browser. It lets your app directly push changes to the browser. A fundamental qualitative enhancement.

4.0 out of 5 stars use C#, Oct. 12 2014
The book is arranged as 5 extended examples of games parleyed in Unity 2d. But first the book prepares by quickly discussing the basics in the introductory chapters. These include the topics of setting scenes, adding characters and code control. At first, I mistook the latter for version control, which is certainly needed for large programming projects! But the code control chapter discusses in broad terms the different types of programming languages, from machine language to assembler to any level of higher languages. More to the point, since the book is about Unity, you find that you can write in 3 languages - C#, UnityScript and Boo. Not bad! This enhances the opportunity for Unity to spread its adoption.

Of these languages, C# is perhaps the one with the most expressiveness. It is equivalent to C++ or java. So if you are from those languages, probably pick C#. As a pragmatic point, it can offer the best performance, and could have the largest networking libraries.

While the choice of UnityScript may be made by those better versed in javascript. The former derives stylistically from the latter.

The text mentions Boo mostly for completeness, and just to remark that it is in the style of Python.

The game example chapters are each concise. Deliberately, the examples are where you can rapidly understand and try. Got to say that for those readers who hail from spending too much time in video arcades, look at the chapter on classic arcade if you want to recreate something from your misspent past.

One game example just starts into the vast arena of a physics engine. Showing how to incorporate realistic effects that let the player take advantage of his pre-existing intuition. I should add that you are not required in this chapter to actually know introductory physics kinematics. But the more you do know, the greater the ability later to customise any physics engine you might use.
