If you need a MySQL installation compiled in “32bit mode”, you’ll not be able to achieve your goal with MacPorts:

The same happens with the port mysql5. You can switch to 32bit by setting build_arch to i386 in the file /opt/local/etc/macports/macports.conf.
So I’ll try to use a precompiled package and hope it’ll work with my development environment.

If you want to remove the dotted border of a focussed html element, you can do this with the following CSS definition:

outline-style: none

You might consider usability problems and accessibility before doing that. I’ll use it for a star rating tool.

If you want to get every line from a file containing foo OR !bar:

(grep foo file.txt; grep -v bar file.txt) | sort -u

“sort” is necessary to filter duplicate generated entries. Alternatively you could also use perl -ne. Hint from Urban.
