REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers. It can be used interactively for simple calculations but also provides a flexible and expressive user programming language. The development of the REDUCE computer algebra system was started in the 1960s by Anthony C. Hearn. Since then, many scientists from all over the world have contributed to its development. REDUCE has a long and distinguished place in the history of computer algebra systems. Other systems that address some of the same issues but sometimes with rather different emphasis are Axiom, Derive, Macsyma (Maxima), Maple, Mathematica and MuPAD. REDUCE primarily runs on either Portable Standard Lisp (PSL) or Codemist Standard Lisp (CSL), both of which are included in the SourceForge distribution. By modern standards, REDUCE is a surprisingly small and compact application, which runs well on all major operating systems.

GeigerLog is a combination of data logger, presenter, and analyzer, and now released as version 1.3 ! Based on Python (Version 3), hence runs on Linux, Windows, Macs, Raspberry Pi, and other. It now also runs on HiDPI screens. GeigerLog can be monitored by SmartPhone; it is WiFi enabled for servers and clients. Initially developed for Geiger counters, it is now a more universal tool, which equally well handles data like temperature, air-pressure, humidity, CO2. Continues to support GQ Electronic's GMC-300/500/600 Geiger counters, RadMon and other IoT devices, Gamma-Scout Geiger counters, audio-clicks producing counters, I2C based sensors. GeigerLog reads data from the devices, saves them to databases, prints to screen and plots as graph of Values vs Time. The graph is auto-updated and can be customized. Quality control using Statistics, Scatter, Poisson Test, FFT & Autocorrelation, and more. New Raspi specific software let it act as a WiFiServer for GeigerLog.
