Should I use #define, enum or const?
...eters probably won't use any less stack than ints" is wrong. If you have a CPU with 8-Bit registers, a int need at least 2 registers while uint8_t needs only 1, so you will need more stack space because you are more likely to be out of registers (which is also slower and can increase code size (depe...

How can I maintain fragment state when added to the back stack?
...s well. It does not only keep fragment state, but also reduces the RAM and CPU load (because we only inflate layout if necessary). I can't believe Google's sample code and document never mention it but always inflate layout.

Find the nth occurrence of substring in a string
...actually have to copy the whole file into memory:
In [4]: %time s = mm[:]
CPU times: user 813 ms, sys: 3.25 s, total: 4.06 s
Wall time: 17.7 s
Ouch! Fortunately s still fits in the 4 GB of memory of my Macbook Air, so let's benchmark findnth():
In [5]: %timeit find_nth.findnth(s, '\n', 1000000)
