Human friendly curses interface for spamdb(8) to manage addresses for the whitelist/greylist. Note: This is for OpenBSD's spamd(8), which has absolutely nothing to do with SpamAssasin's spamd. It's simple, and "just works" ... What more is there to say?

libESMTP is a library to manage posting (or submission of) electronic mail using SMTP to a preconfigured Mail Transport Agent (MTA) such as Exim. It may be used as part of a Mail User Agent (MUA) or another program that must be able to post electronic mail but where mail functionality is not the program's primary purpose. libESMTP is not intended to be used as part of a program that implements a Mail Transport Agent. libESMTP is an attempt to provide a robust implementation of the SMTP protocol for use with mail clients. It is being developed as a reaction to the experience of incomplete or buggy implementations of SMTP and also to help remove the need for the installation of MTAs on workstations which only need them to provide a sendmail command for a mail client to post its mail.

The trader extension is a free open source stock library based on TA-Lib. It's dedicated to trading software developers requiring to perform technical analysis of financial market data. Alongside many indicators like ADX, MACD, RSI, Stochastic, TRIX the candlestick pattern recognition and several vector arithmetic and algebraic functions are present.

One of the aims of this package is to make life easier for useRs who deal with survey data sets. It provides an infrastructure for the management of survey data including value labels, definable missing values, recoding of variables, production of code books, and import of (subsets of) SPSS and Stata files. Further, it provides functionality to produce tables and data frames of arbitrary descriptive statistics and (almost) publication-ready tables of regression model estimates. Also some convenience tools for graphics, programming, and simulation are provided.

[ excerpt from developer's web site ] Using JNI (Java Native Interface), a bit of C code (thanks ugha!), a little manual work and a piece of chewinggum: it is possible to make the public key cryptography quite a bit faster.

Functions from this package are useful for number theory applications. For example, in two-keys cryptography. See /tests/RSA.php in the package for example of simple implementation of RSA-like cryptoalgorithm. See http://chat.finalcombat.com/vayala/big_int/ page for more complex implementation of RSA-like crypto, which supports key generating, encrypting/decrypting, signing and validating of sign. The package has many bitset functions, which allow to work with arbitrary length bitsets. This package is much faster than bundled into PHP BCMath and consists almost all functions, which are implemented in PHP GMP extension, but it needn't any external libraries.

This extension for PHP provides routines for manipulating bitsets.

This extension for PHP provides routines for manipulating bitsets.

This ststs extension for PHP provides few dozens routines for statistical computation.

The package is intended for scientists and engineers who need to manipulate a variety of types of matrices using standard matrix operations. Emphasis is on the kind of operations needed in statistical calculations such as least squares, linear equation solve and eigenvalues.
