True | deong | null | Oh, it's always good to argue with authority, if for no other reason that to prove to yourself that they were right. Theoretical CS isn't my specialty either, but that said, these are basic enough questions that I feel plenty comfortable addressing them...
So the big thing to think about here is that a variable can only represent one thing at a time. So if something is O(N), or O(N^2 ), or O(N\*log(N)), we're explicitly saying that its runtime is always dominated by the size of one particular set of inputs.
For a lot of the problems that we encounter, that's a reasonable expectation. How long does it take to sort an array of numbers? It depends only on how big the array is (ignoring optimizations like bucket sort that don't work in general). We know that you can't do better than O(N\*log(N)) where N is the size of the array. How long does it take to find the optimum tour in a traveling salesperson problem instance? It depends on the number of cities. We can't prove it's optimal, but we don't know of anything better than O(2^N ) where N is the number of cities (the obvious solution is O(N!), but dynamic programming can do a bit better getting it down to that O(2^N ) bound).
I haven't been able to come up with a really simple algorithm that illustrates the concept I want to get across, but we can find examples that aren't too hard to follow. I think a good one might be the [Bellman-Ford algorithm](http://en.wikipedia.org/wiki/Bellman%E2%80%93Ford_algorithm) for finding shortest paths in a graph. Without going through all the details, the skeleton of the algorithm looks like
for v in vertices:
do some stuff
for v in vertices:
for e in edges:
do some stuff
for e in edges:
do some stuff
We can ignore the first and last loops, since the middle one obviously dominates the runtime. Now if that middle loop had been
for v in vertices:
for v2 in vertices:
do some stuff
then we can easily recognize that it's in O(N^2 ) where N = |{vertices}|. Similarly, if both loops were over the list of edges, we could then call N =|{edges}| and it would still be in O(N^2 ). But of course neither of those are what the loop actually said.
If we insist, we can define it as being in O(N) where N = |{vertices}| \* |{edges}|, but this is really misleading. It's telling the casual reader that we have a linear time algorithm, when it's more like quadratic assuming that there are roughly as many vertices as edges. So why not just call it in O(N^2 )? Unfortunately, we can't make that assumption either, and besides, doing that is confusing because what is N? Graphs have vertices and edges, and that's how we normally think of algorithms that work on graphs -- as operating on vertices and edges. So if we try to call it in O(N^2 ), we need to explain what N is. Is it vertices? No. Edges? No. It's some combination of the two that isn't entirely clear.
The solution is simple. We simply say that the algorithm is in O(V\*E) where V=|{vertices}| and E=|{edges}|. This gets across the information that's important. The reader can easily tell how the algorithm behaves.
That's really the key point to be made here. If you have an algorithm whose complexity depends on two different things, it's usually correct to express its complexity as a function of those two things rather than try to smash them together into one quantity that isn't as meaningful to someone trying to understand the algorithm.
In the particular case of the original question here, the distinction isn't quite as obvious. I still think the correct solution is to express the complexity as a function of both the size of the list and the size of the strings involved, but I think it's closer to being a borderline case than my graph example above.

True | checksinthemail | null | Go with what is currently the fashionable, resume building language of the season. A language will typecast you. You don't get any bonus points for jumping the gun and going with a language you *think* is trending towards fashionable, UNLESS you're one of the taste-makers and involved in coding for the language/framework/paradigm.
Avoid at all costs any language (which may be fine and you may be well versed in) that has had it's 5 minutes of fame, like C++ or Java. D and JRuby are adequate replacements.
Avoid any platform primary languages, unless the platform is cool (so, C# is out, although Objective C is still okay - for the moment)
If the choice is between an adequate language with obscene amounts of popularity at the moment, and a near-future tweak on that language, always (ALWAYS) go for the near-future one. This means if you're going to use JavaScript - you should be leaning towards Coffeescript instead. At the very least throw in worker threads, ES6, and local storage use into your JS.

The state-of-the-art algorithms are utilizing a combination of matrix factorization using SVD (singular value decomposition), Restricted Boltzmann Machines (a novel type of neural network), and kNN (nearest neighbor). These are typically combined using a linear combination with learned weights.

True | pedrocr | null | >Although you can try to do the same in C (basically avoiding variable re-assignment entirely) you will quickly notice that the remaining part of the language isn't powerful enough to write sensible programs (in the meaning that it just isn't practical -- the language is probably still Turing complete).
I think this is the gist of your distinction and I agree with it. You can write pure functions in C and in Lisp and you can cause side effects in both as well. But in actual practice pure functions are probably more common in Lisp and the use of side-effects more common in C.
Thanks for the thorough reply.
