Re: [Factor-talk] Newbie problem with 'first program'

[cat via Factor-talk]

I haven't had time to maintain it in a white but 
[Exercism](http://exercism.io), the free and open-source language-learning 
platform, has the beginnings of a Factor language track, which is designed to 
use the Exercism model to help people learn Factor:

OK, I’ve worked through Your First Program and gotten exposure to a few 
concepts (and had fun!). It would be nice if there were a series of such hands 
on tutorials leading me through further steps in my programming education and 
factor education. I don’t suppose that is the case though.  I will continue as 
best I can, stumbling and experimenting, and I”ll make progress, but is there 
anything available anywhere that provides a more structured path?
Just an example to show that despite the First Program tutorial I am still 
fundamentally ignorant:
After playing with my newly built ‘palindrome?’ program, I began getting call 
stack overflow errors.  Ok, but I am flat-footed at this point. What’s the call 
stack? What an overflow? Is my code causing the overflow? How, when it was just 
working a moment since and suddenly produced overflow errors? I’m sure the 
answer is simple and obvious to someone with just a little more experience, but 
what it shows me is that I’m really stumbling in the dark from this point. 
There’s obviously so much more of a very fundamental nature that I need to 
grasp before I even think about more intermediate concepts, let alone advanced. 
 Yet I could not even find an explanation of the stack overflow error and how 
to fix what caused it.  I’ll mess around and search around and figure it out 
eventually, but there must be a more systematic way.
How do I proceed from here in learning factor? And programming?
Andy

Usually you can press the Fn key and then F2 if it’s a dual-purpose button. 
Apple doesn’t think we need Function keys and keeps trying to make them harder 
to use.  (I use a MacBook also).

Ok, I fixed that in Mac preferences, so I’m ok there.

OK, back with my next question, still working on ‘first program’. By the way 
I’m loving the documentation. OK, my question: pressing F2 from the listener, 
on my stock Mac keyboard, give the ‘Brighten screen’ function rather than 
reloading changed files. For now I’m just using “palindrome” reload, but I’ll 
need the F2 reload function sooner or later.  How do I achieve that on this 
keyboard?

That worked John, thank you!  A little knowledge goes a long way.  I’m sure 
I’ll be back with more questions soon.

Re: [Factor-talk] Newbie problem with 'first program'

You mounted the Factor DMG, which is normal, but it is read-only, so you
are getting an error when trying to write files or create directories
inside it.  I recommend copying the factor folder from the DMG into
somewhere else like /Applications and then it should work fine.
