You continue to amaze, Leonardo. To have not been a programmer that
recently, and to have come up with LeoCAD and make it work so well,
it shocks me a little (in a good way). :)

I wouldn't go that far. In fact, I'd caution that we be VERY careful
NOT to believe that for a moment. TLG cares very much about what's
done here, I'm sure, and the moment this effort steps out of hobbiest
"mode" and starts to even APPEAR to affect profits or step onto a
profit center, whether they've developed it yet or not, the developers
of this project with be _sure_ to hear about it.

At this point in my narrative, the 0.75 sources were long gone, the
web site had been taken down (because of the letter) to be replaced
once btopia had been stabilized and was ready to realize. He hadn't
kept a snapshot of this spot in the development, so couldn't give me
back the 0.75 sources, which as I said were actually more developed
than btopia was at that point.

Being a CS student CERTAINLY does not make one a decent software
engineer, nor does having been a lifelone "hacker" (or, if you
prefer "coder"). Good design simply takes lots of pratice coupled
with a sincere review of one's code by talented peers over time (or,
for that matter, self-review of one's own code over time -- this
helps us to realize for ourselves what are important design decisions).

You're reiterating my point for me (though you cut point number 1 of
3). The code started as Amiga code, transmigrated to Linux and X
(which aren't even close to the way Amiga does things), and I was
trying to add in Windows functionality to the system, which had been
developed as a student's side project over time.
I'm not saying that students don't do good coding, but they usually
don't have the time or experience to sit down for a good design at
the start. More often, an idea germinates, some initial success
with the idea leads to an interesting framework around the idea,
and then features are added one-at-a-time on a whim and the
application just snowballs. Rarely is there time or interest in
taking what should have been a simple proof-of-concept or prototype
and starting over with a clean, well-thought out and (most importantly)
extensible design. [Unfortunately, I might add, much of the software
in the professional arena suffers from this methodology as well]
Trying to fit Windows code into the structure he created would have
meant adding an X<->Windows layer. I tried to get him to genericize
some interfaces, so it would be easier to architect other windowing
systems into the program, but that was an uphill battle (understandable,
as he hardly had time to work on the features he wantd to).

Yes, but he felt he needed to rearchitect in order to keep the LEGO
Germany lawyers at bay, and he was making an attempt to start with a
cleaner design, as I've said he should have done earlier. Too bad
the Real World got in the way. :-P

Thanks. At least this shoot-off topic from the discussion has had
some interesting results (or perhaps will). Go Paul! :-)
