You guys are right, I should search for answer by myself.

This is not a PicoLisp specific question.  I'm sure many of us here want to
encourage your interest in general programming concepts, but there are much
better venues for you to get answers to questions like this.  For example,
on youtube the Kahn Academy has excellent tutorials on programming, while
most of them are in the Python programming language, the concepts are
entirely general and translate to all languages, including all lisps.  You
will likely find many lisp tutorials there as well.  As for stacks vs
lists, wikipedia has excellent articles on both:

https://en.wikipedia.org/wiki/Stack_(abstract_data_type)

https://en.wikipedia.org/wiki/Linked_list

You will get detailed responses to your questions on this list if you
constrain them to topics related to PicoLisp.

Hello everyone,
What are all differences of stack and list data structures?

in Linux webcams create device nodes, watch the output of dmesg.

To actually access them it might be handy to pipe from ffmpeg or similar
which will do all sorts of conversion, splitting into single images,
motion detection and who knows what else - if you manage to follow
all stackoverflow posts explaining how to do that:)

Hi,

Oh, sorry! This is probably due to the fact that PicoLisp can only handle UTF-8,
and your symbols are probably not in that encoding.
