...While checking the nRF52811 product specification to learn more about this chip, I found out that it contains a Cortex M4 CPU. You can research some of the existing Forths for these processors (myself I find a tethered Forth convenient to work on CPUs like this).

Sounds like you might want to explore Forth a bit. Punyforth on the ESP8266 is a convenient way to try get started hands-on, Jonesforth if you want to learn how you could go about implementing one.

On bigger devices (PC/SBC/...) with an OS, Tcl/Tk is a wonderfully effective programming tool!

I can suggest to give Future Shock (1970, Alvin Toffler) a go, it too has some thoughts about the effects of over-stimulation. Good thinking :)

Actually, it is an X/Motif program, by Bob Deen in 1994 (according to https://www-mipl.jpl.nasa.gov/vicar_os/v1.0/vicar-docs/VICAR...), and remains in use.

Tcl! See https://www.tcl.tk/doc/engManual.pdf to start to understand why. (For code written in Tcl itself there's also some proposed conventions: https://www.tcl.tk/doc/styleGuide.pdf)

You could import your daily snapshot in a new SQLite DB everyday, then use the sqldiff utility [https://www.sqlite.org/sqldiff.html].

Another option that might fit would be a sort(1) pass on your TSV files (unless you already ORDER BY on the primary key), then using Awk to detect differences, and immediately print out a list of API commands to update your external DB. Awk conveniently handles tabular data, just set the field-separator (FS) to \t in this case (default it splits on all whitespace).

Indeed! Here's two other ones that proved useful and interesting to me:

ARM7/9 types (Cortex like STM32, several NXP LPC, ...): Riscy Pygness - http://pygmy.utoh.org/riscy/

Microchip PIC18/24/30/33 and Atmel Atmega: FlashForth - http://www.flashforth.com/

Enjoy!

I was referring to the Forth stack in my question about what was ment with persistence in this particular case.

Sure thing, read this: https://github.com/zeroflag/punyforth/wiki/Developing-and-de...

Hey, you can access the PunyForth over a TCP session (as implemented here: https://github.com/zeroflag/punyforth/blob/master/arch/esp82...). Not sure what you mean with "persistence", you can write to memory in one session, and read back in another? Or are you talking about the stack here?
