Questions and answers from my journal contents / ask me anything poll.
Probably either learning how to program large applications, or how to use CPAN effectively.
It's easy, I think, to pick up habits while writing small-to-medium Perl scripts that don't scale to large applications. For example, learning how to modularise may be difficult if you're used to writing one-liners and one-filers.
And there are so many modules on CPAN that it can be hard to know whether there's already something that does what you want, so you don't have to re-invent the wheel.
(And sometimes there are so many that it's hard to know which one to pick. Favourites are templating systems, database abstraction schemes, and date/time modules.)
This allows me to study at most universities abroad, as far as I know. Since I'm not a German, it also allows me to study at German universities. (As far as I know, German students who obtain an IB are not allowed into German universities based only on that. I don't know the details, though.)
FWIW, I graduated with a score of 36 (out of 45 possible) points; I like telling Germans that my grade point average was 6.0 since 6 is a failing score in German schools :D.
Er, no? Do I give this impression?
In the entry with the poll, I even wrote
In the end, I'll only take this as a guideline, since I usually post what I think of posting rather than what people expect me to post, but it does influence the entries I make, which (I think) sums it up pretty well.
