Eight Queen Puzzle

Posted by edwardarobinson on July 11, 2012, 10:18 p.m.

The girlfriend and I have started a little game every wednesday we are going to try to give each other a puzzle, we then each have a week to solve the puzzle. This Wednesday I have her the Eight Queens Puzzle. The puzzle is quite a simple one, on a normal eight by eight chess board find a way to place eight queens such that no two queens are attacking each other, in short no two queens should be on the same row, column, or diagonal. Despite being relatively simple the puzzle has lots of history WARNING THIS LINK HAS THE SOLUTION. This week Anna did not give me a puzzle but I am hoping that next week I will have a puzzle from her, another to give her as well as a solution to the Eight Queens Puzzle.

You can find a great example of the puzzle without a solution here.

Site Software Updated

Posted by earobinson on May 27, 2012, 1:12 a.m.

The update from wordpress to my own site on GAE powered by django has been successful. As I said before I will be keeping the old site up so that I can access my old posts but I may migrate them over and remove wordpress completely. I hope that having my own custom site with my own custom code will encourage me to post more content online. One of the things I have created already is a google map that lets you leave a comment on the map at your automatically detected location if you are the first person from your ip to visit the page, I call it Around the World. The next thing I want to create is something that lets me make videos from flickr sets as I just got back from europe and I love watching my pictures scroll by at a super fast speed.

For some time now I have been saying that I wanted to start coding in django on my blog. Over the next week I am going to be moving my blog to GAE using django. I am going to keep my old blog posts for now at http://oldblog.earobinson.org but all new posts will be on earobinson.appspot.org which will take over as the main landing page of earobinson.org in the next month.

Cheers
