NYCPHP Meetup

[Kristina D. H. Anderson]

If anyone wants to write a Taoist poem, in pseudocode, about how NULL 
is like an inning of baseball yet to be played...now THAT would be 
cool.

> As a Lifetime Baseball fan (married over home plate back in 2000), 
career-long web-programmer (I remember when NYPHP was first getting 
started), and long time stalker of this list, I second Kristina's "Love 
It".

> As programmers, we spend a lot of time using metaphors to explain 
what we are doing in a way easily understood by others. I've even 
explained the ins-and-outs of MX records by using a "delivery to an 
upscale apartment building" metaphor.  But the baseball metaphor and 
Tao reference are best I've seen in a while... both for their 
simplicity and universal (at least in North America) appeal.

NULL in either case. If you have an $object and accidently lapse into
