The goal of the lensfun library is to provide an open source database of
photographic lenses and their characteristics. In the past there was an
effort in this direction (see http://www.epaperpress.com/ptlens/), but then
author decided to take the commercial route and the database froze at the
last public stage. This database was used as the basement on which lensfun
database grew, thanks to PTLens author which gave his permission for this,
while the code was totally rewritten from scratch (and the database was
converted to a totally new, XML-based format).
The lensfun library not only provides a way to read the lens database and
search for specific things in it, but also offers a set of algorithms for
correcting images based on detailed knowledge of lens properties and
calibration data. Right now lensfun is designed to correct distortion,
transversal (also known as lateral) chromatic aberrations, vignetting, and
colour contribution of the lens (e.g. when sometimes people says one lens
gives "yellowish" images and another, say, "bluish").
Ploticus is script-driven, which makes it suitable for automated, unattended
uses, or for applications that will be run again and again. Ploticus might be
your choice for stylistic reasons or just because it suits the problem or
application. In general, ploticus is good at making graphs like you would see
in newspapers and news magazines, business publications, journals for medical
and social sciences, and so on.
You can also use Ploticus in combination with standard desktop tools, e.g.
generate data displays using ploticus then import SVG or PNG into PowerPoint,
Word, etc.)
Ploticus is not a function or mathematical plotting package like gnuplot, nor
would it be a good choice for applications where mathematical formulas or
scientific notations are to be rendered as an integral part of the data
display. Ploticus is also not intended as a "marketing" graphics package. Its
goal is to display data crisply without extra decoration and distracting
"dingbats" that cloud the picture. Thus there is little support for 3-D
effects, gradient backgrounds, and so on.
FreeBSD note: the binary is referred to as 'pl' in the source files, but
is installed as 'ploticus' so as to avoid conflicts with other ports.
3[APA3A] tiny proxy 3Proxy (pronounce it as "Zaraza tiny proxy") is really
tiny cross-platform (Win32&Unix) proxy servers set. It includes HTTP proxy
with HTTPS and FTP support, SOCKSv4/SOCKSv4.5/SOCKSv5 proxy, POP3 proxy,
TCP and UDP portmappers. You can use every proxy as a standalone program
(socks, proxy, tcppm, udppm, pop3p) or use combined program (3proxy).
Combined proxy additionally supports features like access control,
bandwidth limiting, limiting daily/weekly/monthly traffic amount, proxy
chaining, log rotation, sylog and ODBC logging, etc. It's created to be
small, simple (I'd like to say secure - but it's just a beta) and yet
functional. It may be compiled with Visual C or gcc. Native Win32 version
included in archive and supports installation as NT/2K/XP service.
Currently 3proxy is tested to work under Windows 98/NT/2000/2003/XP,
FreeBSD/i386, Linux/i386, Linux/Alpha. See Release Notes and Changes for
features list.
3proxy is FreeWare. It can be used under terms of GNU/GPL or under its own
license (please read License Agreement).

LIBSVM is an integrated software for support vector classification, (C-SVC,
nu-SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation
(one-class SVM). It supports multi-class classification.
Since version 2.8, it implements an SMO-type algorithm proposed in this paper:
R.-E. Fan, P.-H. Chen, and C.-J. Lin. Working set selection using second order
information for training SVM. Journal of Machine Learning Research 6,
1889-1918, 2005. You can also find a pseudo code there.
Our goal is to help users from other fields to easily use SVM as a tool. LIBSVM
provides a simple interface where users can easily link it with their own
programs. Main features of LIBSVM include
* Different SVM formulations
* Efficient multi-class classification
* Cross validation for model selection
* Probability estimates
* Weighted SVM for unbalanced data
* Both C++ and Java sources
* GUI demonstrating SVM classification and regression
* Python, R (also Splus), MATLAB, Perl, Ruby, Weka, Common LISP and LabVIEW
interfaces. C# .NET code is available.
It's also included in some learning environments: YALE and PCP.
* Automatic model selection which can generate contour of cross valiation
accuracy.
Nux is a small, straightforward, and surprisingly effective open-source
extension of the XOM XML library. Nux is geared towards versatile embedded
integration and interchange, in particular for high-throughput server container
environments (e.g. large-scale Peer-to-Peer messaging network infrastructures
over high-bandwidth networks, scalable MOMs, etc). But its simplicity also
makes it useful for client side XML query/transformation workflow pipelines.
Features include:
- Seamless W3C XQuery support for XOM.
- Efficient and flexible pools and factories for XQueries, XSL Transforms, as
well as Builders that validate against various schema languages, including
W3C XML Schemas, DTDs, RELAX NG, Schematron, etc.
- For simple and complex continuous queries and/or transformations over very
large or infinitely long XML input, a convenient streaming path filter API
combines full XQuery support with straightforward filtering.
- Glue for integration with JAXB and for queries over ill-formed HTML.
- All this is rock-solid, dependable, well documented, and ships in a jar file
that weighs just 60 KB.

pkg_cleanup finds packages that are not requested by any other installed
package and lets you decide for each one if you want to keep it or delete it.
It also allows viewing the package comment and description.
This program is essentially a clone of pkg_rmleaves except that it shows
the comment and description of packages and does not support GUI dialog(1)
implementations.
LIRC is a package that allows you to decode and send infra-red signals
of many (but not all) commonly used remote controls.
The most important part of LIRC is the lircd daemon that will decode
IR signals received by the device drivers and provide the information
on a socket. It will also accept commands for IR signals to be sent if
the hardware supports this. The second daemon program called lircmd
will connect to lircd and translate the decoded IR signals to mouse
movements. You can e.g. configure X to use your remote control as an
input device.
The user space applications will allow you to control your computer
with your remote control. You can send X events to applications, start
programs and much more on just one button press. The possible
applications are obvious: Infra-red mouse, remote control for your TV
tuner card or CD-ROM, shutdown by remote, program your VCR and/or
satellite tuner with your computer, etc.
nxtvepg - Decoder, Browser and Analyzer for the Nextview
Electronic Programme Guide
nxtvepg is an X11 application to decode, analyze and browse TV programme
schedules transmitted on analog TV channels as defined in ETS 300 707:
"Protocol for a TV Guide using electronic data transmission" by the European
Telecommunications Standards Institute.
nxtvepg enables you to obtain free TV programme listings for all of the major
networks in Germany, Austria, France and Switzerland.
Currently Nextview EPG is transmitted by the following TV networks (note that
each of these EPGs cover not only the provider's programme but also that of many
other networks): Kabel1, 3Sat, RTL-II (Germany and Austria), SF1, TSR1, TSI1,
EuroNews (Switzerland), Canal+, M6 (France), TRT-1 (Turkey).
You will need a bktr(4) compatible tv tuner card with teletext support in order
to use nxtvepg.
It is recommended to check the card's setup before using nxtvepg, e.g. with the
following applications from the ports collection:
multimedia/fxtv for tv tuner and misc/alevtv for Teletext support.
Torrus is designed to be the universal data series processing framework.
Although most users deploy Torrus for SNMP monitoring, it might be useful for
data series of any nature. Tobi Oetiker's RRDtool is used for data storage.
* Configuration compiler and validator. It processes the XML configuration
files and saves the configuration into a database.
* View renderer and the web interface. They generate HTML and the graphical
representation of the datasources and provide user authentication and
authorization. All generated output is controlled by the configuration
parameters and templates. The users can easily create their own
presentation of data series.
* SNMP Collector. Modular collector core architecture allows further
extension with new collector and storage types. Any datasource can have
its own polling schedule.
* SNMP Device Discovery Tool. Devdiscover is a new, modular, flexible, and
expandable tool for automatic generation of Torrus configuration files.
New device types and MIBs are easily added as independent Perl modules.
* Threshold monitor. All data, regardless of their type and nature, can be
monitored according to the user-defined rules. The rules can also include
the datasource-specific parameters, e.g. boundary values etc. The
thresholds are specified by RPN expressions.
