potrace is a Peter Selinger's GPLed utility for tracing
bitmaps - converting them into smooth, scalable images.
It accepts as input a bitmap B/W images (PBM, PGM, PPM
and BMP formats), and returns encapsulated PostScript
(EPS) as the default output. Other output format are
available: PS, SVG, Xfig, PGM, PDF and experimental
GimpPath.
You can create scalable images from scans, such as
logos, hand taken notes, etc. The resulting smooth
images can then be rendered at any resolution.
ssss is an implementation of Shamir's secret sharing scheme for
UNIX/Linux machines. It is free software, the code is licensed under
the GNU GPL. ssss does both: the generation of shares for a known
secret and the reconstruction of a secret using user provided shares.
The software was written in 2006 by B. Poettering, it links against
the GNU libgmp multiprecision library (version 4.1.4 works well)
and requires the /dev/random entropy source.
PEAR::XML_Wddx does 2 things:
a) a drop in replacement for the XML_Wddx extension (if it's not built in)
b) produce an editable wddx file (with indenting etc.) and uses CDATA, rather
than char tags
This package contains 2 static methods:
XML_Wddx:serialize($value)
XML_Wddx:deserialize($value)
Should be 90% compatible with wddx_deserialize(), and the deserializer will
use wddx_deserialize if it is built in.
No support for recordsets is available at present in the PHP version of the
deserializer.
The rencode module is similar to bencode from the BitTorrent project.
For complex, heterogeneous data structures with many small elements,
r-encodings take up significantly less space than b-encodings.
This version of rencode is a complete rewrite in Cython to attempt to
increase the performance over the pure Python module written by Petru
Paler, Connelly Barnes et al. Later, it was forked, enhanced, and
bundled with Deluge. Now, it is re-packaged and distributed by Xpra.
eGenix.com mx Extensions for Python

providing professional quality add-ons for the Open Source Language Python
(see http://www.python.org).
It consists of the following packages:
mxDateTime - Generic Date/Time Types
mxTextTools - Fast Text Processing Tools
mxStack - Fast and Memory-Efficient Stack Type
mxTools - Collection of Additional Builtins
mxProxy - Generic Proxy Wrapper Type
mxBeeBase - On-disk B+Tree Based Database Kit
The Statistics::LineFit module does weighted or unweighted least-squares
line fitting to two-dimensional data (y = a + b * x). (This is also
called linear regression.) In addition to the slope and y-intercept, the
module can return the square of the correlation coefficient (R squared),
the Durbin-Watson statistic, the mean squared error, sigma, the t
statistics, the variance of the estimates of the slope and y-intercept,
the predicted y values and the residuals of the y values.
DigiTemp is a simple to use console application for reading values from
Dallas Semiconductor 1-wire devices. Its main use is for reading temperature
sensors, but it also reads counters and understands the 1-wire hubs with
devices on different branches of the network. DigiTemp now supports the
following 1-wire temperature sensors: DS18S20 (and DS1820), DS18B20, DS1822,
the DS2438 Smart Battery Monitor, DS2422 and DS2423 Counters, DS2409
MicroLAN Coupler (used in 1-wire hubs) and the AAG TAI-8540 humidity sensor.
The inplace(1) command is a utility to edit files in-place through
given filter commands preserving the original file attributes. Mode
and ownership (user and group) are preserved by default, and time
(access and modification) by choice.
Examples:
# Sort files in-place using sort(1):
inplace sort file1 file2 file3
# Process image files preserving time and taking backup files:
inplace -t -b.orig 'convert -rotate 270 -resize 50%% %1 %2' *.jpg
ike-scan discovers IKE hosts and can also fingerprint them using the
retransmission backoff pattern.
ike-scan does two things:
a) Discovery: Determine which hosts are running IKE.
This is done by displaying those hosts which respond to the IKE requests
sent by ike-scan.
b) Fingerprinting: Determine which IKE implementation the hosts are using.
This is done by recording the times of the IKE response packets from the
target hosts and comparing the observed retransmission backoff pattern
against known patterns.
This package is the Flashpix OpenSource Toolkit and is based
on source code obtained from the Digital Imaging Group Inc.
(currently known as International Imaging Industry Association or i3a).
See the file AUTHORS for the origin of this package, the file
COPYING for usage limitations, the file INSTALL for Unix installation
instructions, and the file README.gcc for GNU make based build
instructions.
