It's been a good run, but my thrill for blogging has ebbed. Most of my online conversation occurs on Twitter these days, and my Buckblog has ...

Actually, once you understand this algorithm, I think the best place to go next would be to change it to a breadth-first traversal. The intuition here is that a maze is an undirected graph, and this algorithm constructs the maze by traversing that graph in depth-first order. This is d...
Ryan, regarding "caving so soon and so fast," it wasn't a casual decision. We consulted an attorney, and their professional opinion was that we not fight it. True, we could have looked for a second opinion, but given that the prospect was not exactly sunny, it would have just been (IM...
(Hello Minecrafters! If you’re looking for random mazes you can build in Minecraft, you might be better served by this page I wrote . It’ll give you block-wise schematics for the maze, and will require less mental translation than the demos here. Just don’t use IE—it won’t work right ...
Excellent write-up in helping beginners understand the principles of Rails. Keep’m coming! As Christoffer said, pseudo_id could be a helper, I think it fits fine in the model. I’m sometimes unsure whether to put little functions like that as part of the model or as a helper. Personall...
@Robin, very nice, I love how it’s actually simpler to allow adjacent crossings. I’ll bet it could even be simpler: we probably don’t even need to check the connected status of east/west and north/south pairs during the crossing phase, since they can only be connected if the center ce...

@chaered, it actually does not matter how you define “placed in the maze.” By definition, every cell in the maze must be reachable by every other cell, so regardless of where you are placed, there will be a shortest path to any other cell you designate. And since a shortest path will ...
The difference between protected and private is very subtle, as you can see, which explains why protected is rarely used by most Rubyists. If it is used at all, it is generally as a convention, to document methods that are internal to the class, but which lie closer to the public inte...
