comment Labeling points on a graph with their coordinates in parentheses
good solution but too much white inner spacing in there between the numbers. If these good be squashed closer they will look better.

comment Find positions of items in a list based on neighbours
Use, Position and find() are similar in this case (I've solved this also in M using Position and Cases, but solutions shown here are nicer than what I have). Matlab's find() actually is more flexible than M's Position[]. I mentioned this before, as it can return more information than just the position, it also can return the corresponding values found at those positions. In M, one has to use Positions and then use Extract. Here is Matlab's help on find() mathworks.com/help/matlab/ref/find.html May be in V10, they'll add an option to Position to do the same :)

comment Find positions of items in a list based on neighbours
nice use of MapIndexed. since all the good answers are shown, I tried this in Matlab to see how it will look like, here is the answer: !Mathematica graphics Matlab does not have pure functions (at least not as they work in Mathematica)

comment Applying Labeled Option to Multiple Options
@m_goldberg yes, that is a nice way to do it as well. As typical in Mathematica, there is always at least 10 ways to do the same thing :)

comment Applying Labeled Option to Multiple Options
@Pickett I took it they wanted to put label on the points, with the value of each point. May be I also mis-understood it.

comment How does the speed of WriteString compare to other languages?
@RunnyKine yes, sure, but they just give a general estimate I would think. This is all not a scientific performance study by any means. It is not meant to be. There are many variables involved and to do this right.
