Although I'm quite familiar with Mathematica, I always try to keep an open mind and don't use it as golden hammer. I'm particularly good at things that are fun, for instance

comment Buying a new computer (specifically for Mathematica)
@Mr.Wizard Never needed it since other things need way more time than I could get back by tweaking the overclocking (e.g. me thinking or watching p*rn is one slowing factor). I turned it on for you and uploaded a new benchmark which came from 4.6GHz.

How about the option DisplayAllSteps->True of Animate?

comment Extracting ragged array from an image
@belisarius No, it doesn't force you but no matter what you supply as argument, the output is a bit-matrix. At least this is how I understood it and how it behaves.

comment Extracting ragged array from an image
You should skip the binarize and use a Dilation on the original point image instead. I would have written up an answer, but your reasons for not using an image/integer bases approach are a bit vague. Do you have important reasons why a pixel based approach would not be sufficient?

I should comment more often if it leads to answers instead of comments :-))) +1

comment Unable to compute the area of region
@gpap Why would someone want to calculate the area of the convex hull when he is interested in the area itself?

comment Save as pdf broken in version 10.0.2?
@MathLind The update of Mathematica itself will not happen automatically. I'm not sure if everyone can get the minor updates (like 10.0.1->10.0.2) for free, but you should be able to find out by logging into the [Wolfram user portal](user.wolfram.com). There, I can manage all my licenses, get the new versions, etc..

comment Linux: Mathematica crashes when clicking documentation links very fast
@Öskå It's the same here. Sometimes it crashes after only a few clicks and sometimes I need 50 clicks. But it always crashes. One time, the front end froze without crashing but I had to kill the session.
