Free platform independent software for linux

JGame is a small high-level 2D game engine for producing games on Java platforms. It does a lot of the stuff you need for a game automatically, and "classic" type arcade games can be developed with a minimum of effort.
It is based on sprites with automatic collision detection, and a tile-based background with easy sprite-tile interaction facilities. JGame games can easily be run as stand-alone applications or as applets, and can be scaled to any resolution.
Main features:
- Tested on various platforms; can easily be run as applet as well.
- Ensures optimised and accelerated graphics for a variety of displays; even works well on remote X11 displays.
- The game is programmed at one resolution, but can be scaled to any desired resolution when run.
- Built-in animated "sprite" engine, with easy animation definition.
- Tile-based background handling, with decorative backdrop.
- Automatic collision detection with sprites and background tiles, and easy background tile interaction.
- Load sprites, tiles, and colour fonts directly from sprite sheets.
- Define images and animations in a text file.
Enhancements:
- New platform-independent versions of Point, Rectangle, Color, Font.
- Changes in package structure. Base classes are now in jgame, platform independent implementation details in jgame.impl, platform dependent classes in jgame.platform.
- Major changes in JGEngine/JGCanvas. A platform independent interface JGEngineInterface has been defined. The platform-independent code has been moved to jgame.impl.*, and for each platform there is a platform-dependent version of JGEngine, delegating functionality to jgame.impl.EngineLogic where possible.
- ImageUtil has been split into a platform-independent interface JGImage, and platform implementations JREImage and MIDPImage.
- StdGame now has two versions, the original for JRE and a somewhat simplified version for MIDP.
- The package tree has been changed. The sources are now in src-*, classes are compiled into classes-*. Compilation of the JGame classes and the examples and applications has been split.
- The code has been optimised: object creations in the most important tight loops have been reduced to near zero, repaintBG has been optimised by a factor 2, isOnPF/isInView were optimised.
- a small bug in background copying where the area bounds would exceed the size of the source image was fixed.
- A few methods were added specifically for use the Midlet platform, such as isMidlet(), displayWidth/Height(), setScalingPreferences().
- setCursor has been renamed to SetMouseCursor.
- there is a new engine getTiles method that copies the data into an existing object. Semantics of the getTiles methods in JGObject have been changed to return a local variable with the information copied into it, rather than create an object every time. Semantics of some other methods such as getImage is changed so as not to create a new object every time.
- fixed bug in exitEngine which did not set the JGObject default_engine to null
- fixed access exception occurring in unsigned webstart.
- improved frame skip logic so that game runs smoothly even if the machine is way too slow

iText is a library that allows you to generate PDF files on the fly.

The iText classes are very useful for people who need to generate read-only, platform independent documents containing text, lists, tables and images.

The library is especially useful in combination with Java technology-based Servlets: The look and feel of HTML is browser dependent; with iText and PDF you can control exactly how your servlets output will look.

iText requires JDK 1.2. iText project is available for free under a multiple license: MPL and LGPL.

It supports SMTP authentication and attachments.

USAGE:

OO

use Mail::SendEasy ;

my $mail = new Mail::SendEasy(
smtp => localhost ,
user => foo ,
pass => 123 ,
) ;

my $status = $mail->send(
from => sender@foo.com ,
from_title => Foo Name ,
reply => re@foo.com ,
error => error@foo.com ,
to => recp@domain.foo ,
cc => recpcopy@domain.foo ,
subject => "MAIL Test" ,
msg => "The Plain Msg..." ,
html => "The HTML Msg..." ,
msgid => "0101" ,
) ;

if (!$status) { print $mail->error ;}

STRUCTURED

use Mail::SendEasy ;

my $status = Mail::SendEasy::send(
smtp => localhost ,
user => foo ,

msgid => "0101" ,
) ;

if (!$status) { Mail::SendEasy::error ;}

gtkpod is a platform independent GUI for Apples iPod using GTK2.

gtkpod is a platform independent GUI for Apples iPod using GTK2. It allows you to import your existing iTunes database, to add songs/directories/playlists, to edit ID3 tags, to modify the iTunes database without the iPod connected and to synchronize at a later time. gtkpod also features international charset support for ID3 tags, detects when adding already existing songs, and more.

EiffelVision 2 is a platform independent GUI library.

EiffelVision2 is a nice GUI toolkit abstraction that works on multiple platforms. Based on GTK for Unix and WEL on Windows.

TagUtil is an easy-to-use tagging utility that enables easy insertion of tags into a blog post. Other facilities offered include: Scheduled Pinging, Support for portable Tag Sources (as RDF files), Facility to create and share such Tag Sources (in RDF format), and Updating of Live Bookmarks for selected Technorati tag searches.

(Note: Core functionality is platform independent. However, some peripheral features that involve file write operations would work only on Windows.)
