Apr 23	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.

Apr 20	comment	Efficiently deleting rows in many large text files If no output is expected, would not be `Run` better?
Apr 20	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.
Apr 19	comment	Can TextRecognize read digits? but very nice to play with it!
Apr 19	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`.
Apr 19	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`?
Apr 19	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.
Apr 19	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!
Apr 17	comment	Maximizing a function with assumptions `Solve[f'[s] == 0, s]` says it cannot solve the system.

Apr 13	comment	How to add several Locators to a Graphic with a mouse click? Sorry, I didn't noticed it's you :P. Anyway it's good to have the link as reference for anyone who lands in this related question.

Apr 7	comment	GeoDirection and GeoDistance Memory Leaks: How to Recover the Memory? No, the problem is in the Geo functions, they have the memoization problem.
Apr 7	comment	GeoDirection and GeoDistance Memory Leaks: How to Recover the Memory? It is not a memory leak, it is a memoization problem.
Apr 6	comment	Histograms with pre-counted data sure, I just didn't want to crash my kernel :P.
Apr 6	comment	Histograms with pre-counted data So, your example data could be of this form: `Tally[RandomInteger[1000, 1000000]]`?
