I am teaching computer science at Charles university, I am a bit out of fight to publish as much papers as you can. I have solved a lot of problems at high school and not that much extrovert to publish later. Recently I have put few articles to arxive (about heaps and some puzzle). I am rather correcting mistakes on other's (otherwise good papers) than publishing my owns.

After editing some arimaa wikies, I have written czech version of QR code article on wiki. Then I have edited some math pages like Reed Solomon codes, some cs pages like Top trees and network flows ... .

I am problematic wiki editor as I wrote here only occassionly and I often cross the border of "thinking rather to citing". Probably the most problematic topic is the smallest circle problem where the paper (I was refering to ... MSW) is that abstract that almost nobody here is willing to read it. Or I just read more from the paper then was written in it (personal communication with Emo Welzl and Micha Sharir).

And sometimes I read wrongly ... the smallest circle problem the |R|=3 case returns disc bounded by circle going through all points of R rather then the minimal enclosing disc of R. The definition of b_md differs so b_md({1,2,3},{4}) is defined as the disc with circle going through {1,2,4} (following pictures) on its boundary, making the welzls algorithm fine.
