Target the parts of your applications that take the most time, by Martyn Honeyford "Improving the performance of your applications is rarely a wasted effort, but it's not always clear which functions the program is spending most of its execution time on. Learn how to pinpoint performance bottlenecks using gprof for both user-space and system calls on Linux®."
a research project that allows users to compile C and C++ code that is targeted to run on the open source ActionScript Virtual Machine (AVM2). The purpose of this preview is to assess the level of community interest in reusing existing C and C++ libraries in Web applications that run on Adobe® Flash® Player and Adobe AIR®.
allows for a C,C++,ObjC source file to be "Compiled on Demand" prior to being executed. The source files are compiled and executed on the fly. This allows for C,C++,ObjC to be treated like a scripting language.
a Virtual Globe and World Atlas. Marble offers different thematic maps: A classroom-style topographic map, a satellite view, street map, earth at night and temperature and precipitation maps. All maps include a custom map key, so it can also be used as an educational tool for use in class-rooms. For educational purposes you can also change date and time and watch how the starry sky and the twilight zone on the map change.
a cross-platform, graphical database modeling tool for MySQL. It allows you to create database models from scratch as well as by importing existing databases from SQL or DBDesigner4 models. You can then generate SQL code to CREATE databases, ALTER them, and export in various image formats and PDF/PS. Its extension system allows writing plugins and scripts in Lua, Python, and C++.
Information Retrieval systems where "fuzzy" string matching is a necessity. IR systems that allow users to search for a particular word and all its variants, rather than only matching the user's precise query, normally use stemming to accomplish this. IR systems include desktop and web-based search engines.
open source 3D graphics toolkit, used in visual simulation, games, virtual reality, scientific visualization and modelling. Runs on all Windows platforms, OSX, GNU/Linux, IRIX, Solaris, HP-Ux, AIX and FreeBSD operating systems.
Sponsored by AMD, the Framewave project offers developers unparalleled, code-level access to a vast array of signal and image functions and routines designed with "code faster, faster code" in mind.
a general purpose monitoring platform. First, at run time, Pandora reads static configuration files either from disk or from the network. Second, if told so, Pandora opens a control socket to which commands can be sent. Pandora provides an API with C++, C and Guile bindings to ease the construction of clients. These commands allow queries of the actual configuration of the platform and to perform arbitrary modifications on it.
a Free C++/Python GIS Toolkit for developing mapping applications. Above all Mapnik is about making beautiful maps. It is easily extensible and suitable for both desktop and web development.
an application for viewing and analysing the contents of music audio files, containing advanced waveform and spectrogram viewers as well as editors for many sorts of audio annotations. It supports sophisticated audio selection, looping, and playback features, as well as the Vamp audio feature extraction plugin format.
