As of late clipboard pasting into a terminal sometimes fails (a

this works just fine. But now I fail filling a new table. The table
exists. "mysql>EXPLAIN new_table;" explains and "root@blackbox-one:/#

Hello,
I'm in charge of preparing a computer room for the practices of
"introduction to programming".
One of the tasks is checking that from all the computers in the room
one can execute some programs and link (and compile) against some
libraries.
My first idea was using Autotools (or cmake), but a

It's not, it's quite common. Functions in Python are first-class values,
and we can do things like this:

Thank you. This is extremely helpful. The key that I was missing is that
it's running them outside of the ipy context. I also discovered that if you
call the script .ipy instead of .py, it actually does more or less what I
was expecting -- that is, it allows magic commands, and I got the thing
work

No (I guess).
If you want a better answer, then you'll have to give us a *much* better
question. Get a pixel from *what*? (screen?

Thanks for your reply, MRAB.
I've seen that the child thread has been stoped, it just died in the

clean it, but I didn't do that.
I've implement the thread using List now, thanks again.

I think it should.
Registration only needs to happen once, the module is useless without being registered, no threads nor processes are

I'd be quite happy with importing having a side-effect here. If you
