One thing to note, in line 6 of the book, we check for north and east, and chose either one to link. Somehow, it does not work on this code, I have to use South and East. Will have to check why I can't follow the code as is given in the book
* Re-reading the source code from the book got me to spot my own mistake that makes bidirectional links to not join at all * The code now follows the book exactly
* Dynamic type languages like Ruby and Python tend to leave out details and make things seem like magic. I used to like that about Ruby and Python :P * Now that I'm reading someone else's code, I have to do the interpretation myself, and I hope this is what the short listing on page 40 does. * Based on this however, there may be more Ruby fu to translate in the later pages 8|
* We can now draw the grid with added distances * "Inheritance" in go in not really inheritance in the sense like Ruby, we have to override `String()`, as once promoted to Grid's String() method, we are not able to get to DistanceGrid's `ContentsOf(cell)` method. * Another thing to note, since there is only one `main()`, and the next few pages adds different scripts, which means I might have to split things up or provide command line options.
