The SVGFig package lets you draw mathematical figures in Scalable
Vector Graphics format (SVG), using the Python language.
As a tool, its usefulness lies somewhere between freehand drawing
programs, which don't give you quantitative control over your figures,
and traditional plotting packages, which fit your data into a prescribed
template. SVGFig allows you to draw anything you can express in Python.
SVGFig is particularly suited to handle non-linear geometries. All
lines, including the coordinate axis, curve if passed through a
non-linear coordinate transformation, and coordinate systems can be
nested in trees. This generalizes all the tools necessary for making
plots, so it is easy to create polar plots of radial data, Hammer-Aitoff
projections of the sky, translations in hyperbolic spaces, or experiment
with new representations.
SVGFig also maintains a convenient representation of SVG images as
Python constructs, so you can load graphics from SVG files, dissect
them, manipulate them with an automated script, and save them in batch.
SANE ("Scanner Access Now Easy") is a universal scanner interface.
The value of such a universal interface is that it allows writing
just one driver per image acquisition device rather than one driver
for each device and application. So, if you have three applications
and four devices, traditionally you'd have had to write 12 different
programs. With SANE, this number is reduced to seven: the three
applications plus the four drivers. Of course, the savings get even
bigger as more and more drivers and/or applications are added.
sane-frontends contains frontends to SANE including xscanimage and
xcam. Xscanimage is a GTK-based application for scanning images that
can also be used as a GIMP-plugin, and Xcam is used to get images
from cameras supported by SANE.
This class is a container class for numbers with a number of associated
symmetric and asymmetric errors. It overloads practically all common
arithmetic operations and trigonometric functions to propagate the errors.
It can do proper scientific rounding (as explained in more detail below in
the documentation of the significant_digit() method).
You can use Math::BigFloat objects as the internal representation of
numbers in order to support arbitrary precision calculations.
Errors are propagated using Gaussian error propagation.
With a notable exception, the test suite covers way over ninety percent of
the code. The remaining holes are mostly difficult-to-test corner cases
and sanity tests. The comparison routines are the exception for which
there will be more extensive tests in a future release.
Freevo is an open-source digital video jukebox (PVR, DVR) based on Linux
in addition to a number of open-source audio/video tools. MPlayer is
used to play audio and video files. MPlayer is an excellent media player
that can play most popular file formats. Freevo can be used both for a
standalone PVR computer with a TV+remote, as well as on a regular
desktop computer using the monitor and keyboard.
Freevo is easy to download and install for new users. Most hardware is
supported (graphic boards, sound cards and video capture devices).
The Freevo core is under heavy development. It is mostly written in the
Python programming language which is very well suited for high-level
control applications like Freevo.
OpenQuicktime aims to be a portable library for handling Apple's
QuickTime(TM) popular media files on Unix-like environments. This
project was firstly designed to allow the porting of the 3ivx codec
on any Unix, but is now a completely separate and fully Open Source
project. Details:
- OpenQuicktime library contains no embedded codecs but has a
plugin system to dynamically load audio and video codecs.
- OpenQuicktime contains no colorspace conversion algorithm.
- OpenQuicktime is fully portable and fully configurable with all
the autoconfigure and automake magic we have been able to add.
- OpenQuicktime supports compressed headers (decoding only for the
moment).
- OpenQuicktime supports Quicktime Sound System version 2.
- OpenQuicktime can support any inputs and outputs (file, HTTP,
FTP, RTP, ...), in fact the functions used to read, write and
seek are overloadable.
- OpenQuicktime has an overloadable plugin mechanism. This is a
complex feature which enables any application to use its own
codecs instead of the OpenQuicktime ones.
This is a plugin package for Nagios. Quoting from the
main Nagios package:
Nagios is a host and service monitor designed to inform you of network
problems before your clients, end-users or managers do. It has been
designed to run under the Linux operating system, but works fine under
most *NIX variants as well. The monitoring daemon runs intermittent
checks on hosts and services you specify using external "plugins"
which return status information to Nagios. When problems are
encountered, the daemon can send notifications out to administrative
contacts in a variety of different ways (email, instant message, SMS,
etc.). Current status information, historical logs, and reports can
all be accessed via a web browser.

Xymon is a system for monitoring servers and networks. It has a great deal
of inspiration from the Big Brother monitor, but unlike Big Brother it is
designed to work well whether you need to monitor small network with just
a handful of hosts, or large networks with thousands of hosts.
Xymon is the successor to the bbgen toolkit, which has been available as
an add-on to Big Brother since late 2002. The name change was decided upon
when Xymon acquired enough functionality to be a stand-alone product.
The tools that formed the bbgen toolkit are still present in Xymon
and are quite important for it, so if you have used bbgen before,
Xymon will seem quite familiar.
This is the client.

AxPoint is a Perl module that uses the PDFLib module and the pdflib library
to generate PDF based presentations from XML data sources.
It has the following features:
- Ability to create slideshows with your choice of background image
- Slideshows break down into slidesets, or not at your choice.
- Slides can show bullet points, source code (fixed font), or images.
- Slides can have transition effects (dissolve, box, wipe, etc)
- All elements of a slide can transition in too.
- Text on slides supports bold, italics, and colours. Colours can be any
one of the 16 HTML colours, or defined as hex RGB values.
- Output uses the standard XML::SAX::Writer consumer classes, allowing you
to output direct to a file, or to a string, or however you need to. Very
useful for dynamic web based presentations.
- PDF bookmarks allow direct navigation to any slide.
- Using PDF allows you to go "Full Screen", even on Linux
- Image formats supported include GIF, JPEG, PNG and TIFF
