  1. Seek out and try new things.

  2. When trying something new, do it on a scale where failure is survivable.

  3. Seek out feedback (to determine your level of success) and learn from your mistakes as you go along.

 comment Mathematica output in ASCII or larger text size for the output?
Worked fine with 40 instead of 80 +1, now I want to turn it into text file so I could read the output in my favourite editor ...this is under investigation: img = Import["http://i.stack.imgur.com/NbTGY.jpg"]; grid = ImagePartition[ ImageCrop[ImageRotate[img, 0.7 \[Degree]], {1180, 720}, {-0.15, 0.2}], {118, 119}]; Table[similarity[i, {{x, o, empty}, {"x", "o", " "}}], {i, grid}], mathematica.stackexchange.com/questions/25250/…, a mistake with traversing.

 comment TextRecognize with crosses, circles and spaces results into oddities, why?
I tried to do it for the grid but img = Import["http://i.stack.imgur.com/NbTGY.jpg"]; grid = ImagePartition[ ImageCrop[ImageRotate[img, 0.7 \[Degree]], {1180, 720}, {-0.15, 0.2}], {118, 119}]; Table[similarity[i, {{x, o, empty}, {"x", "o", " "}}], {i, grid}] -- traversing not working correctly?! Wait it does not work because this method works only with specific cross and specific circle?

 comment How to detect crosses and circles in 60x60 raster images?
@george2079 that is a totally new question: perhaps some machine-learning algorithms for this kind of things where the user needs to specify first the ambiguities and then the program would learn with it? The sloppy O is easily 6 and 9: any machine learning specialist to ask a question about this? :)

@Mr.Wizard Testing on Mathematica 9 Ubuntu 12.04 LTS - HP BL460c 2 x X5650 @ 2.67GHz 96 GB RAM server running Mathematica over X, the same errors seem to appear as with my own computer OS X running Mathematica 8 -- yet it is very hard to see the crosses and circles because the font is so small :( I wish I could see it in ASCII so easier to debug...or any easy way to specify the size of the image. Over the SSH, it is pretty slow to adjust things by mouse...

 comment How to detect crosses and circles in 60x60 raster images?
@Mr.Wizard there is one thing I cannot understand: when I run your code, it outputs tiny-tiny O, X and ERRs. Is it possible to get the output as ASCII so easier to read or is there some setup in Mathematica to handle the output format?

 comment TextRecognize with crosses, circles and spaces results into oddities, why?
@belisarius yes but TextRecognize does not work with only a character so a hackish solution -- my goal is to make the space somehow something special so Mathematica would read it as some specifial character, without needing to create odd code. Perhaps fill all spaces with something very distinct and then use TextRecognize?

 comment How to detect crosses and circles in 60x60 raster images?
@belisarius yes but I have different amount of spaces in the grid. My goal is to print readable ASCII output about the image, I cannot neglect the spaces -- possible to make Mathematica read them as some special character or something like that?

This method results into non-robust implementation at least in my Mathematica (one lower than newest), mathematica.stackexchange.com/questions/25250/…. Why?

 comment Import matrices side-by-side separated by TAB
Now you don't understand, I get matrices in ASCII and I can cut/paste/use-any-unix-command to preprocess them to make them easy for Mathematica. How can I reformat many ASCII matrices so easy to plot with Mathematica? Keep everything in separate files or put them to one file like the question with TAB separation?

 comment Import matrices side-by-side separated by TAB
Look I can specify the input format of the matrix myself. Do you mean it is better to create this kind of rule than use some ready import format parameter? My goal is to compare many matrices side-by-side and I decided to use comma to separate matrix entries and TABS to separate different matrices -- there must be some way to create this kind of comparison -- two TABs embedded with extra zeroes? No, looks probably ugly.

 comment Import matrices side-by-side separated by TAB
@AlbertRetey look I want to have that kind of separator -- if I do this I lose the separation between the matrices. I want to compare the matrices side-by-side with some separator.

 comment Import matrices side-by-side separated by TAB
@bills it is the "0\t0" or "0\t1", it should be interpreted as zero TAB zero or zero TAB one -- but it interprets it as a special something?
