Planjure: A* and Dijkstra's in Om
I wrote Planjure to learn ClojureScript and Om. It’s a fun little program.

Computing pioneer Alan Kay tells us that a computer is "an instrument whose music is ideas."

Hey Paypal, why do you need access to my microphone, camera and photos?
Who actually checks the permissions of applications they’re installing? A little while ago a Paypal update stalled because it required extra permissions. This is what happens if an app you have already installed wants more power. I was more than a little surprised with what I found.
