HEALPix is a set of scientific tools implementing the Hierarchical Equal Area isoLatitude Pixelation of the sphere. As suggested in the name, this pixelation produces a subdivision of a spherical surface in which every single pixel covers the same surface area. HEALPix provides various programs and libraries in C, C++, Fortran, GDL/IDL, Java, and Python which facilitate discretization, simulation, processing, analysis, and visualization of data on the sphere up to very high resolution. It is the state-of-the-art program used in astronomy and cosmology to deal with massive full-sky data sets.
Free Chart Geany is a software solution for market technical analysis and charting. It supports major technical analysis indicators like simple moving average, exponential moving average, MACD, relative strength index, Bollinger bands, and parabolic SAR. It includes support for various CSV formats like Metastock 7, Metastock 8, AMI Broker, Yahoo! Finance, Google Finance, and Standard CSV. Various drawing and text objects like labels, trailing text, horizontal lines, vertical lines, trend lines and Fibonacci retracements are provided. It allows quotes to easily be downloaded from Yahoo! Finance or Google Finance.
OZvm is principally a hardware emulation of the Cambridge Z88 portable computer, a Z80 CPU system with 4Mb addressable memory, a monochrome 640x64 LCD, and RS-232 serial port. It allows you to install any ROM or application card binary that also runs on a real Z88 portable. OZvm is also a versatile Z80 assembler debugging environment with a command line, screen activity recording, and Z80 instruction logging. It assists the developer in testing Z80 assembler programming of the Z88 operating system or 3rd party applications.
Klest-crossword is a program for creating crossword puzzles. It comes with more than 1000 puzzles and dictionaries of 31000 Russian words and 41000 English words. Incompletely guessed puzzles can be saved, and crosswords can be compiled automatically and semi-automatically. Crosswords can be printed, and exported as RTF, PDF, PostScript, HTML, Across Lite, JPG, JPEG, TIFF, BMP, XPM, PNG, XBM, PPM, and OpenKlest, and imported from Across Lite and OpenKlest.
Shelk-test is a program for creating tests for students. Tests take up just three modules: creation, testing, and reporting. Shelk-test can insert images into all types of questions, making it possible to create a question such as "What is shown in the picture?" All tests are stored centrally in a SQLite database, increasing reliability and allowing you to have a database file without having to install a database server.
Treba is a commandline tool for training, decoding, and calculating with weighted (probabilistic) finite state automata (WFSA/PFSA). Training algorithms include Baum-Welch (EM), Viterbi training, and Baum-Welch augmented with deterministic annealing. Treba is optimized for speed and numerical stability, and training algorithms can be run multi-threaded on hardware with multiple cores/CPUs. Forward, backward, and Viterbi decoding are supported. Automata for training/decoding are read from a text file, or can be generated randomly or with uniform transition probabilities with different topologies (ergodic or fully connected, Bakis or left-to-right, or deterministic). Observations used for training or decoding are read from text files compatible with AT&T finite state tools and OpenFST.
