The FGI-GSRx software receiver has been extensively used as a research platform for the last one decade in different national and international Research and Development (R&D) projects to develop, test and validate novel receiver processing algorithms for robust, resilient and precise Position, Navigation and Timing (PNT). At present, the FGI-GSRx can process GNSS signals from multiple constellations, including GPS, Galileo, BeiDou, GLONASS, and NavIC. The software receiver is intended to process raw Intermediate Frequency (IF) signals in post-processing. The processing chain of the software receiver consists of GNSS signal acquisition, code and carrier tracking, decoding the navigation message, pseudorange estimation, and Position, Velocity, and Timing (PVT) estimation. The software architecture is built in such a way that any new algorithm can be developed and tested at any stage in the receiver processing chain without requiring significant changes to the original codes.

HP-15C Simulator for Windows, Linux and macOS. Supports data exchange with SwissMicros https://www.swissmicros.com DM15 models.

It is not complete yet, the author states "This is a work in progress and you may consider this increment as a Minimum viable product (MVP) version."

Squares RNG is a counter-based version of Middle Square Weyl Sequence RNG.  Counter-based RNGs have no state and are well suited to parallel processing.  There is no need to maintain or initialize a state.  Squares is faster than Middle Square Weyl Sequence on an Intel Core i7-9700.  Processing speed is, of course, processor dependent and may vary on other processors.  If you are currently using Middle Square Weyl Sequence, you might consider Squares.  It produces data of equivalent quality and is easier to use since there is no state.

This generator passes BigCrush and PractRand.

Xpra is an open-source multi-platform persistent remote display server and client for forwarding applications and desktop screens.
It gives you remote access to individual applications or full desktops.
On X11, it is also known as screen for X11: it allows you to run programs, usually on a remote host, direct their display to your local machine, and then to disconnect from these programs and reconnect from the same or another machine, without losing any state.
It can also be used to forward full desktops, from X11 servers, MS Windows, or Mac OS X.

Xpra also allows forwarding of sound, clipboard and printing services.
Sessions can be accessed over SSH, or password protected over plain TCP sockets with or without SSL.
Xpra is usable over reasonably slow links and does its best to adapt to changing network bandwidth constraints.

Free42 is a re-implementation of the HP-42S Scientific Programmable Calculator and HP-82240 Printer.
It is a complete rewrite, not using any HP code. It does not require an HP-42S ROM image.
Free42 is an Open Source project. The executables and source code are released under the terms of the GNU General Public License, version 2.
