We can sum operations decimal, binary and hexadecimal mixed. Example. - 25 + BIN ('111 ') + HEX (' FF ') -> this is equivalent to adding the integer 25 +7 (binary) +255 (hexadecimal) = 287. Allows use of predefined variables and constants. Creating user functions. It has a programming section through type pascal scripts (still in testing), It has a multimedia viewer to store documentation that we have on hand for our daily tasks. Aside calculators comes with color coded for resistors, inductors and capacitors. Support matrix calculation. Solving systems of n equations. Periodic table of elements.

Sky simulator for Ascom & Alpaca & Indi

Sky Simulator for ASCOM, Alpaca and Indi is a software program designed to simulate an astronomical camera mounted on a computer-controlled telescope. The camera displays images of the night sky based on the telescope pointing-at position and is affected by exposure time and focuser position. The images can be created artificially or using the online deep sky survey. It simulates also a guide camera. mount, focuser and camera rotator if required. You can also use your own mount in the simulation. Simulation of mount polar alignment errors and mount periodic errors is possible. This simulator is a useful tool for testing the focuser routine, astrometric solving, guiding and test run sequences. Star and a deep sky databases are included. For questions, problems, suggestion visit the forum. Ascom installation required. Install instructions for CCDCiel, APT and Nina : https://sky-simulator.sourceforge.io

Bug Finder

This project born a few years ago when I encountered a fatal bug on a production environment, unfortunately not replicable on my development machine. I spent many time finding a solution, using also freeware and commercial third-party tools and libraries, but none helped me because the bug crashed the process, and no of the above tools could be able to catch the exception before the process dying. Also, it was not possible to install a development environment onto the production machines, so the only solution was to develop a debugger which didn't need any user/developer interaction. I used many open source resources, then I decided to make the Bug Finder an open source project. It is built over a pluggable architecture to support other languages different from Borland Delphi (the one I used to develop my faulting application and the Bug Finder too). Here is the article http://www.codeproject.com/Articles/602794/Bug-Finder-a-real-Win32-extensible-passive-debugge .

Tron

Tron is a console application (now discontinued) which simulates user intervention for otherwise unscriptable applications. It can simulate keystrokes, mouse clicks and movements from scripts allowing the control of applications running in the foreground. It can be used to write automated tests for user interfaces or to ease repetitive jobs with applications which do not support scripting natively. It has a modular design which allows it to be extended easily and is not tied to any particular scripting or programming language.
