> Will you guys be posting slides/notes somewhere soon?
As the warm-up while folks were filtering in, I walked through a bruteforce
Obfu soduko that I found linked in the YAPC:Japan proceedings.
http://www.ecclestoad.co.uk/blog/2005/05/
I had no slides. Just code and examples. And the code ... it's so garbage,
I'm embarrassed I haven't finished refactoring, I was only showing the key
lines to answer the open GD quesitons. You'd have recognized the code
layout, I used the same tidy/css combo as for the Advent.
Extra lines/text on GD:Chart - The key item from my presentation was on the
mailing list in February -- to draw lines and letters on top of a GD::Chart,
request an Image Map before plotting and dump it after, request the GD
object, and knock yourself out.
Example (different than shown) -

Data-on-map -- Prime example is
http://ema.arrl.org/fd/ ,
see the About page for credit on maps. Browse around the History section for
lines on maps. Key is to encapsulate Lat-Lon <-> XY mapping for your
base-map.
Numeric data on map -

Lines on Map -
http://ema.arrl.org/fd/history/tour2005.html
and alternate maps.
I also did a quick review of using XML::Twig
http://search.cpan.org/~mirod/XML-Twig-3.23/Twig.pm
to extract the flagged items from my feed-reader's cache to generate a
cheesy, private RSS file for a couple friends to see my latest science news
-- different but not so very different from what we did for Advent. Code
attached.
