Mapbox engineer and data scientist Vladimir Agafonkin recently created this interesting interactive map which allows you to see the graph of how each street is oriented in the current map view. This means that for each street running north/south, a tick would be placed on the north/south radial display. East/west streets get a tick on the east and west sides. As you would expect, the graph over Manhattan's street grid is mostly in two directions, however, even though we conceptually visualize the grid as north/south/east/west in our heads, the islands northeast tilt means the graph actually shows something different. Check out the full map to play around with it in New York City, or other areas around the world

OU Kosher is a website that discusses everything surrounding the laws of keeping kosher in Orthodox Judaism. A recent article on the site reminds readers that, while completely safe to drink, New York City tap water contains microscopic crustaceans, something those keeping kosher cannot consume, and thus, is not a kosher beverage.

Tiny crustaceans called copepods have been found in New York City tap water. The species we are finding primarily is Diacyclops thomasi, along with some Mesocyclops edax and Skistodiaptomus pygmaeus. These tiny crustaceans are ubiquitous in ponds, lakes, and reservoirs. New York City, because of the high quality of its water, is not required by the EPA to mechanically filter its water. Their appearance in tap water as small white specks may represent a significant kashrus issue.
