Knowing your personality type can be really useful. I found these links on the Internet which helps one judge what his personality type is like.
Here is one nice exercise which can be used to decide the personality oneself. I saw somewhere that most programmer and software engineers happen to be INTJ.
Here is another type of analysis. The good thing about this one is it has some tips on how to deal with each type of personality.
WSO2 WSF/CPP 1.0.0 was released sometime back with the intention of providing a C++ API for C++ developers while leveraging the capabilities of WSF/C Web Services Stack. It only had the Client API. With this new release,the product has been significantly enhanced with the addition of a Service API, Code Generation support for C++, and Many WS-Security features. WSF/C++ can be deployed on both Apache2, and IIS. Also it has the stand alone http server as well. You can download WSF/C++ from http://wso2.org/downloads/wsf/cpp.
Here is the complete release note.

WSF/C++ is the latest product from the WSF family of frameworks for developing Web Services with C++. Its client side was released a while back and now the server side has also been added to the stack. This is due to be release soon.
Following are some of the features of the Up coming WSF/C++ 2.0.0.
1. Client and Service API s for providing and consuming Web Services.
2. Support for WS-Security, WS-Secure Conversation and WS-Policy based configuration options.
3. MTOM attachments support.
4. Code generation tool to generate client stubs and service skeletons given a wsdl.
I will go though these futures in detail in future posts.
eAccelerator is a popular php optimizer and a dynamic content cache. By installing an optimizer, a php web site can be optimized to get maximum performance and would result in very quick response times for the clients significantly improving the client experience.
Here we will have a look at how to install this tool with a PHP system which already have installed WSF/PHP. One of the complains I have seen is that eAccelerator does not work properly with WSF/PHP which is not correct. You can easily get both WSF/PHP and eAccelerator running together.
First install WSF/PHP which has been explained in detail in the installation guide. Next download the eAccelerator source code.
Now you are ready to go ahead with the installation.
unzip the source code.
unzip eaccelerator-0.9.5.3.zip
cd eaccelerator-0.9.5.3
type ./configure --help to view the configuration options.
./configure --help
You will find the configuration option --with-eaccelerator-doc-comment-inclusion
Now you are ready to configure and install eaccelerator.
./configure --with-eaccelerator-doc-comment-inclusion
./make
./make install
This will install the eaccelerator shared library to the php extensions directory. Now configure the php.ini settings for eaccelerator.
WSF/PHP uses two log files to log down certain messages useful for tracing and debugging incase of an error. These logs are handled by the underlying WSF/C Framework. It supports a log rotation as well.
Following are the log level supported by WSF/PHP.
Log values are set to the wsf.log_level php.ini entry.
0 -> CRITICAL ( Only critical errors will be logged )
1 -> ERROR ( Errors will be logged)
2 -> WARNING ( Errors and Warnings will be logged)
3 -> INFO ( Errors , Warnings and Information will be logged)
4 -> DEBUG ( All log messages including debug messages will be logged)
When you have enabled log higher log levels, a large number of log messages are done to the log file which result in the log file growing rapidly with the number of messages processed. This would not be a problem if you are running your system for testing. But if you are running it on production this could cause some problems, because we noticed that these is a issue in the log rotation scheme for WSF/PHP 2.0.0. Due to this issue, a number of users have complained that apache stopped working as well. Therefore it is recommenced that you used the log level 0 on production systems.
These days I have been doing a bit of reading on BEPL ( Business Process execution language. ) BPEL plays a vital role in an real SOA deployment.Here are some of the nice tutorial links i found on the web.
1. A Hands-on Introduction to BPEL
2. A Hands-on Introduction to BPEL, Part 2: Advanced BPEL
Both these links are from oracle and involved with oracle process manager. However the BPEL aspect is explained in a very elegant way.
Also you can find some very nice links from apache ODE site
I had the opportunity of reading the book Apache OFBiz Development. Apache OFBiz is a top level project at apache software foundation and has a large code base and an active development community. OFBiz (Open For Business) is a open source enterprise automation software project. It has the capabilities to cater for many business requirements like ERP, CRM , E-Business ect.
Apache OFBiz development book is written in such a manner that even a total new developer to the domain can quickly get started with the software. It begins with the all important aspect of how to obtain the software, how to install and getting started which is absolutely vital.The first chapter contains details on even setting up the eclipse devolvement environment for OFBiz as well. The authors only expect the knowledge of java language since the software is in java.
OFBiz is a software that is built around the popular MVC ( Model View Controller ) architecture. So the book also focuses on each of these aspects thought the book. The first set of chapters focus on explaining the View aspect. For any business application with a front end, the look and feel of the front end, the maintainability and usability of the front end is absolutely vital and the book covers a great deal about it.
From the 2nd to 6 chapter, the book covers creating a webapp with OFBiz, the how to customize it. The book goes in to great deal of detail in explaining the creating a component in OFbiz and then enhancing it systematically. Chapters 3 and four covers screen widgets and Form widgets. It has lots of detail on how to use xml configuration files. Form widgets chapter covers how to create forms , fundamentals of XHTML forms, event handling ect...
Entire chapter 6 has been dedicated to explaining the control servlet ( Controller of MVC). It covers all details you need to know.
Next the book focuses on the Model aspect (Data) of OFBiz. OFbiz has a Declarative Entity Engine ( Database agnostic ). And Chapter 7 and 8 covers all the know how stuff needed for managing the data within OFbiz. It covers Entity Engine concepts, creating and using entities relationship types ... and many more.
Chapter 9 focus on Events. It focus is on Java Events, OFBiz techniques for programing business logic, handling security, .... Chapter 10 covers how to make your business components operate within an SOA model by making services available. It covers in detail "The Service Engine" of the OFbiz software.Also the book covers permissions, security, configurations with SSL, Apache, controlling look and feel, and vital tips and techniques in managing an deploying in a live environment.
What i like about this book is the number of code samples, details explanations, and the coverage of each and every aspect of the software. Being a very large software project , OFBiz has lots of things to cover, and authors does an excellent job in putting together think kind of a comprehensive book. For any developer using OFBiz this is a must have book. It will not only guide you through all the important aspects of OFBiz, but also will serve as a vital reference to look up when ever you need to figure out something.
