comment How to modify the file “KeyEventTranslations.tr” to use Enter to evaluate the current cell?
@renphysics, Regarding your flag, your update only mentions Szabolcs's link. I'll try to address the questions you ask in it: 1) It works only for that notebook because it explicitly sets it only for the EvaluationNotebook[]. You can set it for all notebooks by changing that to $FrontEnd 2) These settings are stored in the object's options and persists across sessions. See Options@EvaluationNotebook[].

comment SparseArray internal structure
Istvan, I've merged as you requested. Please also add the quote above and the example to Szabolcs's question as well, so that parts of Leonid's answer makes sense on that question as well :)

comment Fastest way to create a NxNxNxN dimensional matrix
Ok, but still you ought to provide a representative function for Func, as it is hard to talk about "speed up" without it. If Func happens to have some sort of symmetry, it can be exploited. For example, see my answer here: mathematica.stackexchange.com/a/19801/5 Your question appears pretty similar to that one, but because of a Toeplitz symmetry, it was possible to get the result by different means.

comment Fastest way to create a NxNxNxN dimensional matrix
Please include a working minimal example with a reasonable choice for Func. You might be able to get some speedup with memoization. Some linear algebra manipulations might also help.

comment Area of a convex polygon with a set of points
You can try using FindCurvePath to get your polygon points in order... no guarantees of it working for all input though (in fact, it might fail for anything other than small/toy problems). BTW, this is a duplicate: mathematica.stackexchange.com/q/9406/5

comment Permanently set options such as metric units for W|A queries
"weather in celcius" ==> "Latest recorded weather for Cuciu, Romania"... Sigh. Although, I suppose "weather" in "Celcius", a unit of temperature, is a ridiculous question :D
