+# Random
+
+# Uses
+
+- games
+
+- cryptography
+
+# Unprdictability
+
+- Unsafe randoms can be predicted (shouldn't be used in cryptography)
+
+- Entropy gathering (some OS don't wait on boot to gether entropy, many routers hacked this way)
+
+- /dev/random is not more secure than /dev/urandom (used to be the case)
