DC Food, Beverage, Sights, and Metro Instructions

Instructions for Using the Metro in DC

Before you Go...

  • Make sure you have google maps on your phone. When you ask Google Maps for directions, it will give you an option to use public transportation and will tell you how to get there by metro. It will also show a big "M" in a square in locations where you can find a metro station.
  • Have a printed copy of the DC Metro map. It's very handy for when you are unfamiliar with the sytem (big pdf or smaller for printing).
  • Download either the Lyft or Uber app to your phone, and go through the steps to set up your account. You will have to provide a credit card. You may not use these services at all, but when you need them, they are a total lifesaver. More details on this below.

A simple script to compare using regex versus line-by-line iteration for finding useful info in a large, structured data file.
/*
This is a simple script to compare finding useful data in a large (structured) dataset
using one of two methods:
(a) a single, well crafted regular expression, or
(b) line-by-line iteration using split() and indexOf
The goal was to demonstrate the speed and memory efficiency that regular expressions have.
In my testing, the regex version consistently ran in about 17 ms and used about 60 KB of
memory over 50 runs (on average). On the other hand, the line-by-line iteration easily
took twice as long at about 35 ms and used ten times the memory at over 6,000 KB (again,
