Hybrid energy-efficient digital currency
Novacoin is a decentralized electronic cash system based on an open-source, peer-to-peer internet protocol. It works without a central server or trusted parties. Users hold the ECDSA private keys to their own money and transact directly with each other, with the help of the network to check for double-spending. They are also able to participate in the network protection using own money or computing power. A hybrid Proof-of-Work & Proof-of-Stake scheme is used to provide a protection against double-spend. The main project repository: https://github.com/novacoin-project/novacoin
Solve linear programming problems
Linear Program Solver (LiPS) is an optimization package oriented on solving linear, integer and goal programming problems. The main features of LiPS are: ● LiPS is based on the efficient implementation of the modified simplex method that solves large scale problems. ● LiPS provides not just an answer, but a detailed solution process as a sequence of simplex tables, so you can use it for studying/teaching linear programming. ● LiPS gives sensitivity analysis procedures, which allow us to study the behaviour of the model when you change its parameters, including: analysis of changes in the right sides of constraints, analysis of changes in the coefficients of the objective function, analysis of changes in the column/row of the technology matrix. Such information may be extremely useful for the practical application of LP Models. ● LiPS provides methods of goal programming, including lexicographic and weighted GP methods, which are oriented on multi-objective optimisation.

Open IoT & Smart Spaces framework
Freedomotic is an open source, flexible, secure Internet of Things (IoT) development framework, useful to build and manage modern smart spaces. It is targeted to private individuals (home automation) as well as business users (smart retail environments, ambient aware marketing, monitoring and analytics, etc). Freedomotic can interact with well known standard building automation protocols as well as with "do it yourself" solutions. It treats the web, social networks and branded frontends as first class components of the system.

Generate and solve Travelling Salesman Problem tasks
TSPSG is intended to generate and solve Travelling Salesman Problem (TSP) tasks. It uses Branch and Bound method for solving. An input is a number of cities and a matrix of city-to-city travel prices. The matrix can be populated with random values in a given range (useful for generating tasks). The result is an optimal route, its price, step-by-step matrices of solving and solving graph. The task can be saved in internal binary format and opened later. The result can be printed or saved as PDF, HTML, or ODF. TSPSG may be useful for teachers to generate test tasks or just for regular users to solve TSPs. Also, it may be used as an example of using Branch and Bound method to solve a particular task.

Astrophoto image & video processor. Full cycle with new technology
Astronomy program for selecting, viewing, aligning and stacking images. Creates 16-bit AVI gray/color video files from images series, concatenates videos together into one video file. The program helps to rebuild sequences of images and restore continuous order of files after they were edited, deleted, renamed or moved. PGMania converts images from one format to another. Supports batch converting operations, also for image sequences. Image formats can be any of well known image formats 8/16/32 bpp b/w/c. The program aligns and fits the pairs of images or image series, with each other or over master, calibrates them in pairs. Program detects stars and get stars statistics. Calculates fwhm, snr and star magnitudes. Image editor with alive histogram, contrast stretching, filters, evaluates and post process. XML and txt logging of all actions and results. *) PGMania uses original algorithm for image calibration. No need for dark & bias files for calibration and fit images.
Statistical program, somewhat like shareware DataFit. You may provide a custom template (or exchange the template library with your friends or Internet including sf.net) and test your tabled data. Calculates F-ratio.
