Phinomenal phractions
Background
As many of y'all may know, Phi, or (1+sqrt(5))/2, is the Golden Ratio, a number with a whole lot of interesting properties.
One of these properties are its continuing phraction phorm, or 1+1/(1+1/(1+1/...)). This phinomenal pattern has earned Phi the reputatio...
El'endia Starman, a moderator, but not a PPCG moderator, has recently added an XKCD RSS feed to our chatroom The Nineteenth Byte, apparently based on the suggestion of one other user.
I am vehemently against this addition to our list of feeds for a number of reasons:

The concept of the game is very simple:
Every consonant is doubled and an o is inserted in-between.

We've had a couple of challenges about the Ulam spiral. But that's not enough.
In this challenge we will plot an Ulam spiral on a triangular grid (instead of the usual square grid). Here's a sketch of what the spiral looks like on a triangular grid.
As we know, the Ulam spiral arranges all na...

You are working at Wolfram Alpha, when a big fire occurs, wiping out much of the hardware infrastructure, losing much of the code. Now you are assigned to the natural language team wo...

31 11 09 25 50
32 12 01 08 24 49
33 13 02 00 07 23 48

Yes
I say that we should go ahead with this change.
Apart from simply correctly appreciating the massive amount of effort put into writing good challenges, this would also be a very nice added incentive to start writing questions, especially for existing users who now want to earn more rep. :)
Let's play Ticket to Ride!
(Note, this challenge was inspired by the board game Ticket to Ride, but is massively simplified to a graph-searching problem).
For this challenge, you have a list of cities (nodes), connections (edges), and tickets (point value to make a path between two cities). Yo...
