  • Iris - A ISLisp Implementation
    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

  • FGI-GSRx software receiver | National Land Survey of Finland
    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.

    Wiki of devine, a member of 100 rabbits https://wiki.xxiivv.com/site/hundred_rabbits.html
    Lots of interesting ideas about programming, simplicity etc.
    For example, Catclock was originally an X10 program by Tony Della Fera, Dave Mankins, Ed Moy, Deanna Hohn and Philip Schneider, crafted for entertainment, in the late 1980's. It was also ported to the Plan 9 operating system by Tom Duff. https://wiki.xxiivv.com/site/plan9.html

  • How SQLite Is Tested
    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.

  • From ‘guix environment’ to ‘guix shell’
    While this blog article is about a new feature of the Scheme-based Guix Linux package manager, it contans the following interesting observation about erroneous shell settings: "it’s not uncommon for the shell to mess up with the whole environment. Why? Because, contrary to documented practice, it’s quite common for users to define or override environment variables in the startup files of non-login shells, ~/.bashrc for Bash, ~/.zshrc for Zsh. Instead, environment variable definitions should go to the startup file of login shells—~/.bash_profile, ~/.profile, or similar. But let’s face it: it’s a subtle distinction that few of us know or care about."
