Ivy is a simple protocol and a set of open-source libraries and programs that allows applications to broadcast information through text messages, with a subscription mechanism based on regular expressions.
Ivy libraries are available in C, C++, Java and Perl, on Windows and Unix boxes and on Macs. Several Ivy utilities and hardware drivers are available too.
Ivy is currently used in research projects in the air traffic control and human-computer interaction research communities as well as in commercial products. It is also taught to CS students.
Ivy is a CENA product.
Main features:
- Ivy is not based on a centralised server. Actually, Ivy is mostly a communication convention, implemented through a collection of libraries for various languages and platforms. The current version of the Ivy protocol is version 3, which has been stable for the last 3 years.
- Language bindings are available in C (Unix and Windows), C++ (Mac, Unix, Windows), Java and Perl. There have been successful uses through the C library
- Messages are formatted in text, and subscriptions are based on regular expressions. Plans to move to an XML-based subscription language are on their way.
- From the programmers point of view, Ivy is an information broadcasting channel. The main functions are:
- connecting to a bus. Example: IvyInit (b, "192.126:2011")
- sending a message. Example: IvySend (b, "HELLO %s", world)
- binding a message pattern to a callback function. Example: IvyBind (b, "HELLO (.*)", cb)
- the main loop. Example : IvyLoop ()
- Subscriptions are managed on the emitters side, which limits the actual network traffic.
- Direct point-to-point messages are also available.
- Ivy was designed by a research group in Human-Computer Interaction, with the goals of connecting applications written on different toolkits/languages/platforms (such as an OpenGL application on a SGI connected to a PerlTk application on a Linux box), while keeping it simple: no server to be lauched and supervised, a simplistic API, and a communication model compatible with classical event-based GUI progamming. We think we have somewhat reached our goal...
Enhancements:
- This release mostly contains bugfixes and code cleanup.

timeclock software is an application for employees to use as a timeclock. An employee time and attendance system keeps track of when your employees sign in and out of work.

This information can then be compiled to produce the total hours worked and the amount that the employees should be paid.

Timeclock-software.nets free software product will be a simple solution to allow your employees to record their time in one central location for easy access.

The Software Packager module is designed to provide a common interface for packaging software on any platform. This module does not do the packaging of the software but is merely a wraper around the various software packaging tools already provided with various operating systems.

This module provides the base API and sets default values common to the various software packaging methods.

Job Costing Software project is the first step to improving profitablity on your projects. A web-based job costing product makes it easy to view or update your job costs quickly.
View your project cost status in real time to make more accurate decisions. Export your costs to an excel spreadsheet for reporting or printing.
Two user levels allow your suppliers to enter costs directly without the ability to edit other costs. Improve your project decision making with free job costing software.
Everybody knows how important it is to create an accurate estimate of a jobs total costs. Unfortunately, most project managers are so busy they dont have time to gather the information needed to accurately calculate costs as the job progresses.
Job costing software makes the cost projections for you, freeing up your time to better manage the project.
Enhancements:
- This release fixed a few bugs in the database library files.

Bio::Genex::Software is Perl module with methods for processing data from the GeneX DB table: Software.

SYNOPSIS

use Bio::Genex::Software;

# instantiating an instance
my $Software = Bio::Genex::Software->new(id=>47);

# retrieve data from the DB for all columns
$Software->fetch();

# creating an instance, without pre-fetching all columns
my $Software = new Bio::Genex::Software(id=>47);

# creating an instance with pre-fetched data
my $Software = new Bio::Genex::Software(id=>47, fetch_all=>1);

# retrieving multiple instances via primary keys
my @objects = Bio::Genex::Software->get_objects(23,57,98)


# retrieving all instances from a table
my @objects = Bio::Genex::Software->get_all_objects();

# retrieving the primary key for an object, generically
my $primary_key = $Software->id();

# or specifically
my $sw_pk_val = $Software->sw_pk();

# retreving other DB column attributes
my $name_val = $Software->name();
$Software->name($value);

my $version_val = $Software->version();
$Software->version($value);

my $type_val = $Software->type();
$Software->type($value);

my $con_fk_val = $Software->con_fk();
$Software->con_fk($value);

Each Genex class has a one to one correspondence with a GeneX DB table of the same name (i.e. the corresponding table for Bio::Genex::Software is Software).
Most applications will first create an instance of Bio::Genex::Software and then fetch the data for the object from the DB by invoking fetch().

However, in cases where you may only be accessing a single value from an object the built-in delayed fetch mechanism can be used. All objects are created without pre-fetching any data from the DB. Whenever an attribute of the object is accessed via a getter method, the data for that attribute will be fetched from the DB if it has not already been. Delayed fetching happens transparently without the user needing to enable or disable any features.

Since data is not be fetched from the DB until it is accessed by the calling application, it could presumably save a lot of access time for large complicated objects when only a few attribute values are needed.
