This one is interesting to me because there are things I wish I didn't have to know that I have had to know.
But here's the list of things I have never had to worry about (9 years):
Relational databases
CSS
Assembler
And for the things I have had to use:
Regular expressions
Big O
Trees/Graphs
Big/Little Endian
64 vs 32-bit programming
Threading... THREADING!
JVM tuning
Manual memory management
Now I'm sharing this list because I personally think the software industry is converging on web development. There is actually a huge world out there beyond web development where some of these more esoteric seeming things have mattered.
