Free integration software for linux

Blogger Integration is a package that can be used to import a blog published in Blogger.com into another site. The project uses the blog page files exported with Blogger FTP blog publish support.
The class can process one or more blogs by parsing the blog page files to extract the posts, comments, images, etc. The processed blog pages can be rendered and published in another site with a different template.
This package can also integrate imported blogs with a site published with osCommerce.
Enhancements:
- The "Add to Yahoo" and "Add to Google" buttons are now inserted into the blog.

Mergence is a high performance, open source HL7integration engine and application platform. It was developed to fill the need for an open source, fully transactional healthcare integration system capable of handling millions of messages per day, and thousands of concurrent LLP connections. Mergence is based on Apache ServiceMix, a lightweight enterprise service bus which conforms to the JBI standard, and HAPI, an excellent opensource HL7v2 API. We plan to support HL7v3 in the next release.
Mergence is still in heavy development, and documentation is still lacking, but the current release is already production-ready if you dont mind working with some XML. We have a well-tested and solid core in place, which is fully usable. Development of an AJAX administration console is underway and is the main focus of the 2.0 release.
We hope to have more complete documentation available in the next week.
Main features:
- Fully open source, under the GNU General Public License
- Built on standards-based technologies.
- End-to-end persistence with global transactions so no message can ever be lost.
- High-throughput, asynchronous architecture.
- Message vault with encrypted storage (embedded or external DB).
- Flexible message routing and transformation.
- Scriptable using Groovy
- Extensive logging, monitoring, and alerting system.
- Supports active clustering.
- Many bundled connectors, and compatible with any ServiceMix JBI component.
- NIO TCP connectors which can support thousands of concurrent connections.
- Support for processing/transforming flat files of unlimited size.
- Hot deployment of new components and configurations.
- JBI extensions for easily developing new HL7 components.

Smarty and MIME message integration is a PHP class library that can send e-mail messages using Smarty templates.

This package can be used to compose and send e-mail messages using Smarty templates.

It wraps around Smarty and MIME message class by Manuel Lemos, and prepares the body and headers of the messages to send.

It can set several message options at once passing an array of options values.

Currently it supports options to define HTML or text message template files, the sender, recipient, bounce and reply names and addresses, whether to send messages in plain text, HTML or both, whether to automatically wrap the message text, message character set, and the bulk precedence header to prevent that notification messages be returned due to temporary delivery errors.

Once the message options are set, the class composes and send message according to the specified option values.

Site Tools is a collection of Modules for perl that allow easy template integration, SQL forms creation, tables, sessions, and various other things that make web development a little easier to manage. Requires the SQLObject and PObject classes available on my project page. I have stopped developing these classes in favor of the Template Toolkit, it is a lot more robust and mod_perl aware, please use that instead.

To install everyhthing, follow the next instructions:

perl Makefile.PL
make
make test
make install

Basic documentation can be found through perldoc Site. It has pointers to other modules to look at.

Jitterbit is an open source integration tool that delivers a quick and easy way to configure, design, deploy, and test integration solutions. It supports most standards-based protocols, including Web Services (SOAP), XML, and connectivity to popular databases.
Jitterbit is designed with ease-of-use in mind. You can download the suite for Linux or Windows in minutes. Once installed, you can quickly build and run complex integration processes without development efforts and take advantage of support from the Jitterbit open source community.
Jitterbit tools let you point-and-click to configure all aspects of an Integration:
- Define integration operations including source and target systems
- Create document definitions, from simple flat file structures (e.g. comma delimited) to complex hierarchic files structures.
- Use a drag-and-drop mapping tool to transform data between your various system interfaces.
- Set schedules, create success and failure events and track the results for your integration operations.
Enhancements:
- Fixed bug 1757864: insert/update fails if target key value contains () or (). (2007-07-20)
- Fixed the bug that the xml node to be created should not containing the order marker (@1, @2...) in the name. (2007-07-19)
- Add data type "float4" as t_float to the data type map. (2007-07-19)
- Fixed the problem of "< null >" string in the internal file for flat database. Symptom was that "< null >" would show up in the target, and that IsNull() would return false even when the source was null. (2007-07-16)
- Fixed the problem in the swapping of db columns for single table db to hierarchical transformation. (2007-07-14)

PDL::GSL::INTEG is a PDL interface to numerical integration routines in GSL.

This is an interface to the numerical integration package present in the GNU Scientific Library, which is an implementation of QUADPACK.

Functions are named gslinteg_{algorithm} where {algorithm} is the QUADPACK naming convention. The available functions are:

gslinteg_qng: Non-adaptive Gauss-Kronrod integration
gslinteg_qag: Adaptive integration
gslinteg_qags: Adaptive integration with singularities
gslinteg_qagp: Adaptive integration with known singular points
gslinteg_qagi: Adaptive integration on infinite interval of the form (-infty,infty)
gslinteg_qagiu: Adaptive integration on infinite interval of the form (a,infty)
gslinteg_qagil: Adaptive integration on infinite interval of the form (-infty,b)
gslinteg_qawc: Adaptive integration for Cauchy principal values
gslinteg_qaws: Adaptive integration for singular functions
gslinteg_qawo: Adaptive integration for oscillatory functions
gslinteg_qawf: Adaptive integration for Fourier integrals

Each algorithm computes an approximation to the integral, I, of the function f(x)w(x), where w(x) is a weight function (for general integrands w(x)=1). The user provides absolute and relative error bounds (epsabs,epsrel) which specify the following accuracy requirement:

|RESULT - I| y} is specified in which case the reason of failure will be printed.

You can nest integrals up to 20 levels. If you find yourself in the unlikely situation that you need more, you can change the value of max_nested_integrals in the first line of the file FUNC.c and recompile.
Please check the GSL documentation for more information.

SYNOPSIS

use PDL;
use PDL::GSL::INTEG;

my $a = 1.2;
my $b = 3.7;
my $epsrel = 0;
my $epsabs = 1e-6;

# Non adaptive integration
my ($res,$abserr,$ierr,$neval) = gslinteg_qng(&myf,$a,$b,$epsrel,$epsabs);
# Warnings on
my ($res,$abserr,$ierr,$neval) = gslinteg_qng(&myf,$a,$b,$epsrel,$epsabs,{Warn=>y});

# Adaptive integration with warnings on
my $limit = 1000;
my $key = 5;
my ($res,$abserr,$ierr) = gslinteg_qag(&myf,$a,$b,$epsrel,
$epsabs,$limit,$key,{Warn=>y});

sub myf{
my ($x) = @_;
return exp(-$x**2);
}
