annoying google

At some point, google search results stopped linking directly to the destination, instead, they changed to point at http://www.google.com/url?BIGUGLYMESS, which I normally don't mind, but when the url links to some resource you want the URL for that your webbrowser downloads, it's quite annoying.

Bleh.

unholy python

import dis, sys

def return_value_used():
    frame = sys._getframe(2)
    code = frame.f_code.co_code[frame.f_lasti:]
    try:
        has_arg = ord(code[0]) >= dis.HAVE_ARGUMENT
        next_code = code[3 if has_arg else 1]
    except IndexError:
        return True
    return ord(next_code) != dis.opmap['POP_TOP']

def foo():
    if return_value_used():
        return 42
    print 'doom'

foo()
print foo()

--
This outputs:
doom
42

Well that's... unholy.
