The TkinterTreectrl module wraps the treectrl Tk extension for use with Python/Tkinter. The treectrl widget allows you to create fancy things like sortable multi-column list boxes and hierarchical tree views in Tkinter. The package also includes a ready to use multi-column listbox widget, scrolled Treectrl, and multi-column list box widgets plus a generic ScrolledWidget class that makes it quite easy to add one or two static or automatic scroll bars to any listbox-alike Tkinter widget.
GridPort is a simple and robust open standard for portlets based on HTTP. It aims to be a simple, scalable distributed composition independent of implementation technology. Transparent collaboration and an SOA paradigm from both interface and data perspectives are encouraged. Component types include portal, proxy for asynchronous multi-casting, and portlets. The purpose of this project is to develop mainly the specification alongside a prototype to enable development of these components in any programming environment and operating platform, which is why its central protocol is HTTP 1.1.
NSFFT is yet another FFT library for performing 1-dimensional fast Fourier transforms. It is a simple, small, and portable library, and it is efficient since it can utilize SIMD instruction sets in modern processors. It performs multiple transforms simultaneously, and thus it is especially suitable for digital signal processing.
SLEEF (SIMD Library for Evaluating Elementary Functions) is a library that facilitates programming with SIMD instructions. It implements the trigonometric functions, inverse trigonometric functions, exponential and logarithmic functions in double precision without table look-ups, scattering from, or gathering into SIMD registers, or conditional branches. This library also includes some functions for evaluation in single precision.
