Where in an ELF executable do various types of strings live?

Inspired by "How to waste a lot of space without knowing": http://glandium.org/blog/?p=2361

Test file:

$ cat /tmp/test.c
char *ptr_global = "ptr_global_string";
char array_global[] = "array_global_string";

Keith gave me the hook-up on turning NASA images into a high-quality movie. I had tried twiddling knobs starting from a basic ffmpeg incant:

ffmpeg -r 10 -i frame%03d.jpg frames.mov

but the movies looked terrible.

"""
Generally if you're making a movie out of separate frames, I prefer to use png2yuv and mpeg2enc from the mjpegtools package instead of ffmpeg -- it's pretty clean code designed for this task instead of an assemblage of random libraries.

I have a table of accounts and a table of transactions.	There's	a
one-to-many relationship between accounts and transactions;                                                                                                                                                      
transactions.account_id is a foreign key into accounts.	For all
accounts where < 50% of transactions are authorized, I want to
get the account id and that percentage:

SELECT a.id, SUM(t.authorized=1)/COUNT(*) AS percentage
FROM accounts a, transaction_info t
WHERE a.id=t.account_id
GROUP BY a.id
