RE: [K12OSN] Dropbox directory permissions



I'm not sure what language they are using now, but we have been teaching
programming here since 1999. Started with Pascal, and then went into
Java. I'd imagine they use Python now considering. The thing is we have
a teacher come over from the local college, and there is only one class
a semester. It may have changed, I don't get over to the High school
much.

This is kind of a caveat....

Robert,

What grade level are you teaching them programming (I am assuming
python) at? Did you find the curriculum or develop it yourself? Is this
most of your students' first exposure to programming or are they
introduced to it in lower grades with kturtle or something similar? I am
trying to get our school to teach something other than keyboarding and
office to our students and I think programming would be perfect. Anybody
else having any luck with programming classes?

I thought about this but what's to stop a kid from just copying it
him/herself without chmoding it. Also,  shouldn't your chmod be 750
since you don't want others to be able to read and thus copy it out of
Dropbox_directory?
And what about /temp where everyone has read/write access?

The reason I am being so anal about the security is because I give my
classes programming tests and I don't want them being able to copy
anothers solution. After having a chat with a friend about this,  I
think the best solution may be to simply ask the kids to save their
solution as their username.py in their own home dir. Then I write a
script that I run as root at the end of class to collect the
solutions.
Concerning /temp: will anything bad happen if I temporarily (during
the exam) disable writing or reading to /temp?
