Artur’s test

The monk climbs the mountain from 6am to 6pm. And the next day while he is descending from 6am to 6pm, a priest climbs. The priest gets to the top at 6pm, which is the same time that the monk gets to the bottom.

Is there a time that they are ever at the same height?

I solved this equationally at shopzilla somehow. I solved it graphically at shopzilla. The next day, I realized, that the picture of someone going down the other side was a red herring: if I had only reflected the downward trip on the upward trip, I would have noticed that they would cross paths!

My second technical test at IMDB

1. If a SELECT is running too slowly how would you debug it?
2. why not index a bunch of individual fields in a database
3. Class::DBI iterators - how are they implemented? Are they efficient?
4. how does CDBI differ from other DBIx::*
5. least favorite Perl feature
6. what are you going to learn next about Perl?

I cannot mount my 320gb external scsi hd

Here is the report from /var/log/syslog when I mount this drive:
