Another mathematics blog, found on John D. Cook's blog https://www.johndcook.com/blog/2018/09/24/riemann-hypothesis-the-fine-structure-constant-and-the-todd-function/

Information on the Computers available over the Internet from the LCM through SSH.

M_Map is a set of mapping tools written for Matlab (it also works under Octave). M_Map includes:
1. Routines to project data in 21 different projections (and determine inverse mappings), using spherical and ellipsoidal earth-models.
2. A grid generation routine to make nice axes with limits either in lat/long terms or in planar X/Y terms.
3. A coastline database (with 1/4 degree resolution).
4. A global elevation database (1 degree resolution).
Hooks into freely available high-resolution coastline and bathymetry databases.
5. Other useful stuff.

I have not found out which license is used.

This repo is an implementation the Plan 9 cpu command, both client and server, for Linux. More detail is available in the CPU chapter of the LinuxBoot book. https://book.linuxboot.org/cpu/
Unlike the Plan 9 command, this version uses the ssh protocol for the underlying transport. It includes features familiar to ssh users, such as support for the ssh config file.

The cpu command lets you log in from a local system to a remote system and see some or all of the files (how much is up to you) from the local system.

This is wonderfully convenient for embedded systems programmers. Because some or all the files can come from your local machine, including binaries, the only thing you need installed on the remote machine is the cpu daemon itself.

Another blog I discovered via Sacha Chua's blog https://sachachua.com/blog/2024/02/2024-02-26-emacs-news/
The pseudo-Wiki https://svbck.org/page/index.html sounds like an interesting idea for my own pages, so does the fact that the pages on on https://svbck.org/ are generated using org-mode https://svbck.org/page/colophon.html

Blog, mostly about experimenting with an Emacs Lisp byte compiler and interpreter implemented in Rust.

Hints for using emacs' ediff mode to compare files.

Ideas about reducing the dependence on big companies. See also the author's blog, which contains interesting articles such as

Just what it says in the title.

The PX5 RTOS is ULTRASMALL (< 1KB for minimal use), enabling its use in some of the most memory-constrained devices. It is one of the smallest RTOSes available, requiring less than 1KB of FLASH and 1KB of RAM on typical 32-bit microcontrollers. I have not found out how it is licensed.
The company also offers https://px5rtos.com/px5-net/, a TCP/IP implementation.
