How does a hash table work?
...m? OK, so suppose we use another algorithm that outputs a different number based on the book name. Then later on, if I were to find that book, how would I know which algorithm to use? I'd use first algorithm, second algorithm and so on until I find the book whose title is the one I'm looking for?

What is the maximum recursion depth in Python, and how to increase it?
...
In my case i forgot the return statement in the base case and it went on to exceed 1000. Python started throwing this exception and i was amazed, because i was sure about the no. of stacks its going to create to run it.

This is approximately twice as fast as a regex or search based solution, but that depends completely on the length of the querystring and the index of any match
the slow regex method I benchmarked against for completions sake (approx +150% slower)

How do I print the full value of a long string in gdb?
...n of that string:
(gdb) p/x (char[10]) *($ebx)
$90 = {0x61,
0x73,
0x64,
0x66,
0x61,
0x73,
0x64,
0x66,
0x65,
0xa}
This may be useful if you want to debug by their values

Computational complexity of Fibonacci Sequence
...is asymptotically O(2n). You can then prove your conjecture by induction.
Base: n = 1 is obvious
Assume T(n-1) = O(2n-1), therefore
T(n) = T(n-1) + T(n-2) + O(1) which is equal to
T(n) = O(2n-1) + O(2n-2) + O(1) = O(2n)
However, as noted in a comment, this is not the tight bound. An interestin...

Append an object to a list in R in amortized constant time, O(1)?
...n performance. For example, the by_index solution, a very popular solution based on the frequency with which I find it in other SO posts, took 11.6 milliseconds to append 2000 objects, and 953 milliseconds to append ten times that many objects. The overall problem's time grew by a factor of 100, so ...
What's the fastest way to delete a large folder in Windows?
...r /s/q foldername
This is nearly three times faster than a single rmdir, based on time tests with a Windows XP encrypted disk, deleting ~30GB/1,000,000 files/15,000 folders: rmdir takes ~2.5 hours, del+rmdir takes ~53 minutes. More info at Super User.
This is a regular task for me, so I usually ...

@Florin - there is no difference re "stack based" between the two. Static fields are just as much "external state", and will absolutely be shared between callers. With instances, there is a good chance that different threads have different instances (a common pattern)...
