• Camera and Image recognition

  - by kjh

  I recently watched a youtube video where a guy got a camera to recognize when a rubik's cube was held up to it, and it captured the 9 square color combination before snapping a picture of the cube and displaying the 3x3 grid on the screen of his computer. What kind of programming is this and where would I start reading to get into this sort of thing? specifically, controlling a camera, and getting it to pick out certain parts of an image and translate that data.

  - by stephan

  I want to write a module on one html site - I will never leave the site I think about two possible concurrent basic approaches: We go into the module by use only a specific function (with specific params - everything which will happen, happen there - logic, exception handling etc) We go in by using one handler-fct, which manages some kind of action & a dataArray (depending on the action also fcts will be called - but not directly maybe for exception handling) So what you prefer?!

• Challenging question find if there is an element repeating himself n/k times

  - by gleb-pendler

  here how it's goes: You have an array size n and a constant k (whatever) you can assume the the array of int type tho it kind be of whatever type but just for the clearane let assume it's an integer. Describe an algorithm that finds if there is an element/s that repeat itself at least n/k times... if there is return one - do it in linear time running O(n) Imortent: now the catch do this algorithm or even pseuo-code using a constant usage of memory and running over the array only TWICE!!!

• xslt or php for rendering output

  - by Arsenal

  I'm creating something where users can upload an xml and data get's imported to the database. Now I'm building some kind of a preview page where users will get to see how their input will look once it's stored. What would be the fastest (in execution time), using XSL to transform the xml to a html page, or using php to render the output? My guess is XSL is far more suitable (+ faster) for this (and by using a DTD there's no need for code written validation, right?)

  Hi, I have some windows command line applications, in binary form (I do not have the source code) which I use frequently. Sometimes I need to run them in Linux machines, and it works perfectly under wine (wine is not an emulator).
