ISLisp in JS/Go: Standards-compliant Lisp smaller than Common-Lisp.
Note that the on-line JavaScript version does not handle #x prefixes correctly.
Integers are also limited to 31 bit:
(expt 2 31) => -2147483648
in contradiction to https://islisp-dev.github.io/ISLispHyperDraft/islisp-v23.html#integer_class

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.

This repository documents how to implement custom FIDO2 extensions. It contains supplementary material to our paper at ETAA 2021. We describe how to implement extensions on all parts of the FIDO2 stack: On the relying party (website), on the client (browser), and on the authenticator (hardware token).

A password manager. It's a lot like pass ("the standard unix password manager") - which I have been using up 'til now - but it uses age instead of GPG to do the heavy lifting. Written in Ruby

Kalibrate, or kal, can scan for GSM base stations in a given frequency band and can use those GSM base stations to calculate the local oscillator frequency offset.

Description of the test methods used for SQLite. The statements
 Valgrind is a simulator - it simulates an x86 running a Linux binary. (Ports of Valgrind for platforms other than Linux are in development, but as of this writing, Valgrind only works reliably on Linux, which in the opinion of the SQLite developers means that Linux should be the preferred platform for all software development.)
are interesting, I did not get this from a casual reading of Valgrind's documentation.
