+========
+
+Numeric Literals
+----------------
+
+- numbers can be followed by the letters `f`, `L`, `UL` or some other things, to specify the type
+- numbers can be sepcified in dec, oct, hex, bin
+ - `0324` is oct
+ - `0xF3` is hex
+ - `0b010101` is bin
+- numbers can be secified in scientific notation like so, `1.532e23`
+
+
+Permanent Storage
+-----------------
+
+- EEPROM is a tiny hard-drive
+
+- `#include <EEPROM.h>`
+- `byte read(int addr)`
+- `void write(int addr, byte value)`
+- `void update(int addr, byte value)`
+- `int length()`
+
+- update is better the write
+
+- Some preprocessor trickery could be used to make this work like a memory allocator
+
+- the EEPROM can be used as an array, called `EEPROM`
+ - this would be nicer for the preprocessor trickery
+
+- someone else already did this
+ - `put(int addr, value)`
+ - `get(int addr, value)`
+ - these are most likely defined as overloaded functions, not pre processor macros, meaning structs wont work
+ - get is doing some wacky c++ stuff to not require an `&`
