Lurker is not just another mailing list archiver. It is capable of handling gigabytes of mail without slowing down. Lurker has been designed to scale to support sites with thousands of concurrent users and hundreds of new messages a second. If you run a high-volume mailing list archive, you should seriously consider lurker for this alone. To facilitate finding interesting data, lurker supports: * full keyword search by body, subject, author, ... * a graphical representation of message relationships * charts of the current activity about a topic * searching lists or queries around an estimated time * signature verification to confirm the author * messages markup to find related information As one would expect, lurker also supports file attachments, multiple languages, message threading, gpg key photo ids, a transactional database, automatic timezone detection, render caching, xml customization with xslt and css, multiple front-ends (3-tier deployment), and many other buzz words.

The xmailbox program displays, by default, an image of a mailbox. When there is no mail, the image shown is that of a mailbox with its flag down. When new mail arrives, the image changes to that of a mailbox with the flag up, its door open and a letter visible inside. It can also optionally play a sound through the sound-card. The NCD audio server, the rplay sound package, FreeBSD Sun-compatible audio drivers, and an external sound player program are supported. By default, pressing any mouse button in the image forces xmailbox to remember the current size of the mail file as being the ``empty'' size and to change its image accordingly. In addition, the user can optionally invoke his/her favorite mail retrieving program.

KBruch is a small program to practice calculating with fractions and percentages. Different exercises are provided for this purpose and you can use the learning mode to practice with fractions. The program checks the user's input and gives feedback. FEATURES - Arithmetic excercise: in this exercise you have to solve a given fraction task. You have to enter the numerator and the denominator. This is the main exercise. - Comparison excercise: in this exercise you have to compare the size of two given fractions, using the symbols >, < or =. - Conversion excercise: in this exercise you have to convert a given number into a fraction. - Factorization excercise: in this exercise you have to factorize a given number into its prime factors. - Percentage excercise: in this exercise you have to calculate percentages.

This module is an extension to the Math::Symbolic module. A basic familiarity with that module is required. Math::Symbolic offers some builtin simplification routines. These, however, are not capable of complex simplifications. This extension offers facilities to override the default simplification routines through means of subclassing this module. A subclass of this module is required to define a simplify object method that implements a simplification of Math::Symbolic trees. There are two class methods to inherit: register and unregister. Calling the register method on your subclass registers your class as providing the simplify method that is invoked whenever simplify() is called on a Math::Symbolic::Operator object. Calling unregister on your subclass restores whichever simplification routines where in place before.

REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers. It has been produced by a collaborative effort involving many contributors. Its capabilities include: * expansion and ordering of polynomials and rational functions; * substitutions and pattern matching in a wide variety of forms; * automatic and user controlled simplification of expressions; * calculations with symbolic matrices; * arbitrary precision integer and real arithmetic; * facilities for defining new functions and extending program syntax; * analytic differentiation and integration; * factorization of polynomials; * facilities for the solution of a variety of algebraic equations; * facilities for the output of expressions in a variety of formats; * facilities for generating optimized numerical programs from symbolic input; * calculations with a wide variety of special functions; * Dirac matrix calculations of interest to high energy physicists. It is often used as an algebraic calculator for problems that are possible to do by hand. However, REDUCE is designed to support calculations that are not feasible by hand.

Sort files or its standard input using the bogo-sort algorithm described in the Jargon File <http://www.catb.org/~esr/jargon/>. A quote from the Jargon File 'bogo-sort' entry: ...The archetypical perversely awful algorithm (as opposed to _bubble sort_, which is merely the generic bad algorithm). _Bogo-sort_ is equivalent to repeatedly throwing a deck of cards in the air, picking them up at random, and then testing whether they are in order. It serves as a sort of canonical example of awfulness. Looking at a program and seeing a dumb algorithm, one might say "Oh, I see, this program uses _bogo-sort_." Esp. appropriate for algorithms with factorial or super-exponential running time in the average case and probabilistically infinite worst-case running time. Compare _bogus_, _brute force_, _lasherism_...

[ excerpt (with adaptations) from developer's README ] ffmpeg is a hyper fast realtime audio/video encoder, a streaming server and a generic audio and video file converter. It can convert a standard video source into several file formats based on DCT/motion compensation encoding. Sound is compressed in MPEG audio layer 2 or using an AC3 compatible stream. What makes ffmpeg interesting ? - Simple and efficient video encoder: outputs MPEG1, H263, Real Video(tm), MPEG4, DIVX and MJPEG compatible bitstreams using the same encoder core. - Hyper fast MPEG audio layer 2 compression (50 times faster than realtime on a K6 500). [snip -> rest on website below] ffmpeg is made of two programs: * ffmpeg: soft VCR which encodes in real time to several formats. It can also encode from any supported input file format to any input supported format. * ffserver: high performance live broadcast streaming server based on the ffmpeg core encoders.

check_multi is kind of a wrapper plugin which takes benefit of the Nagios 3.x capability to display multiple lines of plugin output. It calls multiple child plugins and displays their output in the long_plugin_output. A summary is given in the standard plugin output. The child return code with the highest severity becomes the parent (check_multi) plugin return code. The configuration is very simple: a NRPE-stylish config file contains a tag for each child plugin and then the check command line. check_multi can cover complex Business Process Views - using a builtin state evaluation mechanism. The second benefit is cluster monitoring with no need for extra services. All you need is provided by check_multi. LICENSE: GPL2 or later

This is an SNMP message encoding and decoding library, providing very low-level facilities; you pretty much need to read the SNMP RFCs to use it. It is, however, very fast (it's more than an order of magnitude faster than Net::SNMP, and it can send a request and parse a response in only slightly more time than the snmpd from net-snmp takes to parse the request and send a response), and it's relatively complete --- the interface is flexible enough that you can use it to write SNMP management applications, SNMP agents, and test suites for SNMP implementations. The package also includes NSNMP::Simple, which lets you get or set a single OID via SNMP with a single line of code. It's easier to use, and roughly an order of magnitude faster, than Net::SNMP.

iLBC (internet Low Bitrate Codec) iLBC is a FREE speech codec suitable for robust voice communication over IP. The codec is designed for narrow band speech and results in a payload bit rate of 13.33 kbit/s with an encoding frame length of 30 ms and 15.20 kbps with an encoding length of 20 ms. The iLBC codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets. Features: * Bitrate 13.33 kbps (399 bits, packetized in 50 bytes) for the frame size of 30 ms and 15.2 kbps (303 bits, packetized in 38 bytes) for the frame size of 20 ms * Basic quality higher then G.729A, high robustness to packet loss * Computational complexity in a range of G.729A * Royalty Free Codec
