@riley The #IrOBEX standard is part of the whole #IrDA specification...

The most interesting part is the #LowLevel stuff, cuz theoretically one could just apply that to any optical system ranging from consumer LEDs to Laser pointers to fiberoptical assemblies.

  • But most importantly I do think that IrDA would work great at a diagnostics / negotiation system for the revised #RONJA PtP link that @stman is working on, aiming to do 100 Mbit/s Ethernet with cheap COTS parts.

As IR will be extremely quickly attenuated by the slightest amount of atmospheric moisture (aka. rain and fog) using visible light spectrum is an easier workaround.

  • Plus that tech he's working on could yield a better short-range, contactless data exchange protocol where WiFi, and Bluetooth are not desireable and where passive security-by-design is desireable.

Now if we'd strictly use it as *assistance* tool, stop clogging up git issues and make them performant enough to run on modern NPU+GPU combos this would and could actually be great!

I wrote a short description of how lisp is coded by writing lisp sequences (lists), and the low level dotted cons view of the lists.

I wrote a funny piece of lisp that outputs a lower triangular emacs orgmode matrix depiction of a lisp form.

Which leaves me wondering, does anyone "use" or otherwise think about (a . (b . NIL)) the dotted cons way of writing lists while programming?
