e4Graph is a C++ library that allows programs to store graph-like data persistently and to access and manipulate that data efficiently. With e4Graph, you can arrange your data in the most natural form that reflects the relationships between its parts, rather than having to force it into a table-like format. The e4Graph library also allows you to concentrate on the relationships you want to represent, and not on how to store them in a database. You can modify data items, and add and remove connections and relationships between pieces of data on the fly. e4Graph allows you to represent an unlimited number of different connections between pieces of data, and your program can selectively manipulate the data according to the relationships it cares about, not having to know about other connections represented in the data set.
Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
Ecawave is a simple graphical audio file editor. The user-interface is based on Qt libraries, while almost all audio functionality is taken directly from ecasound libraries. As Ecawave is designed for editing large audio files, all processing is done direct-to-disk. Simple waveform caching is used to speed up file operations. Ecawave supports all audio file formats and effect algorithms provided by ecasound libraries. This includes OSS, ALSA, aRts, over 20 file formats, over 30 effect types, LADSPA plugins, and multi-operator effect presets.
eCos (Embedded Configurable OS) is an open source, configurable, portable, and royalty-free embedded Real Time Operating System. It is written in C++, provides all the usual OS things. You configure the OS so that the parts you don't need aren't loaded to the embedded system. eCos is released under a modified GPL that allows for its use in embedded systems without having to GPL the embedded application.
EO is a templates-based, ANSI-C++ compliant evolutionary computation library. It contains classes for any kind of evolutionary computation (specially genetic algorithms) you might come up to. It is component-based, so that if you don't find the class you need in it, it is very easy to subclass existing abstract or concrete class.
The ESP Package Manager (EPM) is a simple tool that generates software and patch distributions in various formats, including AT&T software packages ("pkg") used by Solaris, Debian ("dpkg"), HP-UX software packages ("swinstall" or "depot"), IRIX Software Manager ("inst" or "tardist"), portable (installation and removal scripts with tar files), and Red Hat Package Manager ("RPM").
erikyyyphone is a very old internet audio conferencing application. The last version was december 1996. It has now been updated to nowadays library status and added autoconf+automake. Multiple persons can talk to each other. It uses very little bandwith and can handle network lags intelligently.
EText Reader (ETR) is a program for reading ETexts from Project Gutenberg texts. It allows selection of font, and foreground and background colors, as well as persistant reading position and bookmarking. It supports browsing, searching, and direct downloading of Project Gutenberg ETexts. It features a built-in online dictionary for instant word definitions while reading.
