Quantum GIS (QGIS) is a user friendly Open Source Geographic Information
System. QGIS supports vector, raster, and database formats.
QGIS is licensed under the GNU GPL.
Some of the major features include:
- Support for spatially enabled PostGIS tables
- Support for shapefiles, ArcInfo coverages, Mapinfo and other formats
- Raster support for a large number of formats
- Identify features
- Display attribute tables
- Select features
- GRASS Digitizing
- Feature labeling
MyPaint is a fast and easy open-source graphics application for
digital painters. It lets you focus on the art instead of the
program. You work on your canvas with minimum distractions, bringing
up the interface only when you need it.
MyPaint comes with a large brush collection including charcoal and
ink to emulate real media, but the highly configurable brush engine
allows you to experiment with your own brushes and with not-quite-natural
painting.
This Perl extension aims to cut down the size of PNGs. Users pass a PNG to
various functions (though only one presently exists -
Image::Pngslimmer::discard_noncritical($blob)) and a slimmer version is
returned. Image::Pngslimmer is designed for use where PNGs are being
generated on the fly and where size matters - eg for J2ME use. There are
other options - probably better ones - for handling static PNGs.
and more image types.
Processing is an open source programming language and environment
for people who want to program images, animation, and interactions.
It is used by students, artists, designers, researchers, and hobbyists
for learning, prototyping, and production. It is created to teach
fundamentals of computer programming within a visual context and
to serve as a software sketchbook and professional production tool.
Processing is an alternative to proprietary software tools in the
same domain.
Peps will preprocess encapsulated Postscript files for conversion by
Ghostscript into bitmaps. It provides variable levels of resolution and
anti-aliasing. You can use it as a stand-alone Postscript-to-bitmap
conversion program, or use it on-line to create bitmaps on the fly and send
them out to a web browser, even compressing them if the browser supports
gzip compression.
Xpeps is peps with X11 support.
An Internet Relay Chat client written in perl, that uses a
perl-based scripting language. It is small (150k or less), fast, and
gives you a good chance to practice your perl skills. :)
It has an interface that closely emulates ircII and comes with
some useful sample scripts that will get you started on IRC quickly. No
knowledge of perl is necessary to run the client although it is helpful
if you plan to do any scripting.
Zinnia is a simple, customizable, and portable online hand recognition system
based on Support Vector Machines. Zinnia simply receives user's pen strokes
as a sequence of coordinate data and outputs n-best characters sorted by SVM
confidence. For portability's sake, Zinnia does not include any rendering
functionality. In addition to recognition, Zinnia provides training module
that allows one to create any hand-written recognition systems with low-cost.
This port provides Python interface to the library.

The com.oreilly.servlet package contains a set of useful utility classes
for servlet developers. Included are classes to help servlets parse
parameters, handle multipart requests (file uploads), generate multipart
responses (server push), negotiate locales for internationalization,
return files, manage socket connections, and act as RMI servers, among
other things. There's even a class to help applets communicate with
servlets. The package was developed by Jason Hunter for his book "Java
Servlet Programming" published by O'Reilly. See:
