  • I hate that I can't decide on anything…
    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

  • Brain dump - Nicolas Martyanoff's blog
    I have seen this before, but apparently I had not bookmarked it. Today I read the statement "As usual, the best way to figure out how something works is to get rid of the high level tools and try to do it on your own." which resonates with my experience on https://www.n16f.net/blog/building-erlang-applications-the-hard-way/
    https://www.n16f.net/blog/improving-git-diffs-for-lisp/ looks useful too.

  • The Industrial Grade PX5 RTOS
    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.
