a bit off topic for Python Tutor, but I am think there are decent odds
that folks here both know good resources and have an idea of what
level would be appropriate for me. So, I hope no one minds.
A recent thread on comp.lang.python has touched on to what extent C
was written in C. I know PyPy aims to implement Python in Python. I
believe I've heard that many lisp fans think you don't have a language
unless you can write the language's interpreter in the language
itself. (Perhaps one or more of these claims is a bit inaccurate, but
the substance seems right.)
This sounds, to the untutored, rather like magic. (It reminds me of a
line from the German mathematician and philosopher, Gottlob Frege,
who, in a book on the foundations of arithmetic, characterized an
opposing position as akin to "trying to pull yourself out of the swamp
by your own top-knot" -- which, I can only assume, is even funnier in
the original 19th c. German ;-) Naively, one thinks that to write
anything in C, you'd have to *have* C to write in, etc.
Now's not the time in my life to start a comp. sci. degree. So, my
1) What would be good terms to google for to find an explanation of
how the seeming magic doesn't violate all reason?
2) Much harder, so please pass unless you've a link you know of
off-hand: any recommendations of particular things that I could read?
Thanks and best,
