Abstraction 
by Alex Martelli 

Abstraction is a powerful servant, but a dangerous master. We code,
design, think, debug ... on a tower of abstractions. Spolsky's Law
tells us that "All abstractions leak". This talk explores why they
leak, why that's often a problem, what to do about it; I also cover
why sometimes abstractions SHOULD "leak", and how best to produce 
and consume abstraction layers.


..... 8:55 PM to 9:20 PM  ................
Mapping and Random Access

Mapping is a rapid-fire audience announcement of topics 
the announcers are interested in. 

Random Access follows immediately to allow follow up 
individually on the announcements and other topics of 
interest.
