Fityk is nonlinear curve-fitting and data analysis software. It allows data visualization, separation of overlapping peaks, and least squares fitting using standard Levenberg-Marquardt algorithm, a genetic algorithm, or Nelder-Mead simplex method. It knows about many functions (mostly bell-shaped, like Gaussian, Loretzian, Pearson 7, Voigt, Pseudo-Voigt, and Doniach-Sunjic) and user-defined functions can be easily added. It also enables background subtracting, data calibration, and task automation with a simple script language. It is mainly used to analyze powder diffraction patterns, chromatography, photoluminescence, infrared, and Raman spectroscopy, but it can be used to fit analytical functions to any kind of data.
TAO Translator (formerly, The Advanced Online Translator) uses online translation services to provide translations. Currently supported services: Google Translate (supports translation, language detection, dictionary, and reverse translations for single words); Microsoft Translator, a.k.a. Bing Translator (supports translation only); Yandex.Translate (supports translation and language detection); and Yandex.Dictionaries (supports dictionary with synonyms and reverse translations). More services are possible in the future.
Linux Test Project is a joint project started by SGI, OSDL, and Bull developed and maintained by IBM, Cisco, Fujitsu, SUSE, Red Hat, Oracle, and others. The project goal is to deliver tests that validate the reliability, robustness, and stability of Linux. Currently it contains more than 1000 syscall test cases, I/O and AIO stress test cases, a few Linux kernel device drivers, a well maintained fork of the Open POSIX Testsuite, a real-time test suite, and more.
