The Spam Bouncer is a set of procmail recipes, or instructions, which
search the headers and text of your incoming email to see if it meets
one or more of several categories (known addresses, rogue ISPs, bulk
mail software etc etc).
The Spam Bouncer sorts suspected spam into two categories -- mail from
known spam sources which is definitely spam, and other mail which is
probably spam, but might also be legitimate. It then tags this email
with appropriate headers giving the spam classification, and responds
according to the parameters you have set.
If you keep SquirrelMail behind a password-protected directory on your web
server and if PHP has access to the username and password, this plugin will
bypass the login screen and use the provided username/password.
If this plugin enabled and the information isn't present, it doesn't crash
or produce error messages. It just doesn't automatically log you in. If the
user/pass information does not work for the IMAP server, this still displays
the login form, just in case the web server password and IMAP password are
not synchronized.
A collection of some tests commonly used for identifying outliers:
- Chi-squared test for outlier
- Test for outlying or inlying variance
- Dixon tests for outlier
- Grubbs tests for one or two outliers in data sample
- Find value with largest difference from the mean
- Critical values and p-values for Cochran outlying variance test
- Critical values and p-values for Dixon test
- Calculate critical values and p-values for Grubbs test
- Interpolate tabularized distribution
- Remove the value(s) most differing from the mean
- Calculate scores of the sample
Concorde is a computer code for the traveling salesman problem (TSP)
and some related network optimization problems. The code is written
in the ANSI C programming language and it is available for academic
research use; for other uses, contact bico@isye.gatech.edu for
licensing options.
Concorde's TSP solver has been used to obtain the optimal solutions to
106 of the 110 TSPLIB instances; the largest having 15,112 cities.
The Concorde callable library includes over 700 functions permitting
users to create specialized codes for TSP-like problems. All Concorde
functions are thread-safe for programming in shared-memory parallel
environments; the main TSP solver includes code for running over
networks of Unix workstations.
clBLAS
a software library containing BLAS functions written in OpenCL
The primary goal of clBLAS is to make it easier for developers to utilize the
inherent performance and power efficiency benefits of heterogeneous computing.
clBLAS interfaces do not hide nor wrap OpenCL interfaces, but rather leaves
OpenCL state management to the control of the user to allow for maximum
performance and flexibility. The clBLAS library does generate and enqueue
optimized OpenCL kernels, relieving the user from the task of writing,
optimizing and maintaining kernel code themselves.
GeoGebra is a dynamic mathematics software that joins geometry,
algebra and calculus. It is developed for education in secondary
schools by Markus Hohenwarter at the University of Salzburg.
You can do constructions with points, vectors, segments, lines,
conic sections as well as functions and change them dynamically
afterwards. Equations and coordinates can be entered directly.
Thus, GeoGebra has the ability to deal with variables for numbers,
vectors and points, finds derivatives and integrals of functions
and offers commands like Root or Extremum.
GeoGebra received several international awards including the European
and German educational software award.
gdcalc is a financial, statistics, scientific and programmers
calculator for Unix. The GUI was written with glade(1) and uses the
Gnome/Gtk+ toolkit - so it may well be compatible with themes and
other whiz-bang features of those systems.
gdcalc has both Algebraic notation (ie. conventional, TI or Casio
style) and Reverse Polish Notation (RPN or Hewlett-Packard style).
If you've not heard of RPN before, you are probably familiar with
algebraic calculators. Very briefly, while simpler and more natural
to use, RPN calculators need some study eg. they have an Enter key
instead of the equals key.
The dynamic mathematics software Geonext establishes new ways of teaching and
learning mathematics. It offers opportunities of visualisation that can't be
realised on paper or blackboard and with traditional construction tools.
Geonext enables autonomous and cooperative learning of mathematics in the
classroom. It encourages an active discovering approach to mathematical
thinking. Geonext can be used at school and at home for free (GPL).
Therefore the software can be handed out to students without any copyright
problems (GPL).
Geonext can be used from elementary school up to calculus at high school and
in teacher-training at university in a manifold and flexible way.

This library provides a number of common functions and types useful in
statistics. We focus on high performance, numerical robustness, and use
of good algorithms. Where possible, we provide references to the
statistical literature.
The library's facilities can be divided into four broad categories:
* Working with widely used discrete and continuous probability
distributions. (There are dozens of exotic distributions in use; we
focus on the most common.)
* Computing with sample data: quantile estimation, kernel density
estimation, histograms, bootstrap methods, significance testing, and
autocorrelation analysis.
* Random variate generation under several different distributions.
* Common statistical tests for significant differences between samples.
LTL is a C++ class template library for scientific computing which provides
high performance via SSE3 floating point support for vector operations.
Useful for array processing, image processing, FITS and ASCII I/O, and linear
algebra (astronomical and scientific computing, in short). LTL provides
dynamic arrays of up to 5-dimensions, subarrays and slicing, support for fixed
size vectors and matrices including basic linear algebra operations, expression
templates based evaluation, and I/O facilities for ascii and FITS format files.
Users of the boost and blitz++ library may find the cross-pollination of these
unique features to be fruitful.
