comment How to completely reinstall Wolfram Workbench on linux
Did you remove the preferences directory /home/.../.eclipse? Maybe it helps to clean it completely.

comment How do you convert a string containing a number in C scientific notation to a Mathematica number?
@GeorgeWolfe because it might lead you to a code leak. What if there is dangerous code within the string? Or something innocent like a equal sign (=) may set any of your variables.

comment Why do I keep getting 0.06 with WorkingPrecision->1?
Yep, I was also trying to understand where the 0.06 came from, and if you try InputForm /@ Union[RandomReal[UniformDistribution[], 1000, WorkingPrecision -> 1]] you will see the actual real numbers you get, and all are fractions of 16.

@Mr.Wizard I would say this is similar to this one: mathematica.stackexchange.com/questions/4212/…

comment What format to use to store expressions in database?
For example ToString[x, InputForm] will let you go back to MMA but it would be better to answer @tkott to get a better answer.

comment Thousands separator (comma) option for NumberString/StringCases?
ImportString does many tricks, but sometimes is too slow. Anyway it's a very good option if you don't want to build your own transformation.

comment Having the derivative be an operator
@celtschk you are totally right. I should not answer at nights... I will change it to a non-conmutative way.

comment How to solve a problem in relative motion?
When you use recursion in that way, you need to define everything for the case 0, in your example code you have not defined Pxi[0], Pyf[0], Pxf[0]; define them and you will get rid of the $RecursionLimit error.

comment Reproducing nested loops using Map?
Table approach is very useful and makes very clear code. I use to recomend its usage too. The only detail to take into account is that sometimes you need to Flatten the output.

comment Can TextRecognize read digits?
Yes, doing some test, I would have expected something like this to work: TextRecognize[Rasterize[5]]. And it seems that image size matters a lot: TextRecognize[Rasterize[50868, ImageSize -> 300]] vs TextRecognize[Rasterize[50868]]. Something else to take care when using TextRecognize.

comment Can TextRecognize read digits?
If I try TextRecognize@d2[[1]], it doesn't work. Neither works for me TextRecognize@ImageAssemble[d2[[1 ;; 2]]], but TextRecognize@ImageAssemble[d2[[1 ;; 3]]] does. Do you know any minimun requirements for TextRecognize?

comment How to visualize/edit a big matrix as a table?
Works very quick!!! And expression capacity is already there (you can enter whatever in your cells and it works nice). Now to replace excel let's add capacity for Column/Row references to cells :P.

comment How to visualize/edit a big matrix as a table?
In your editMatrix function after your edit, you changed m by a, which is wrong. Something else, to make it work properly, you need to add Attributes[editMatrix] = {HoldAll}. It's a very nice solution!
