h7

- questions...

attendance

a few C programs to play with...
- statically linked
- dynamically linked

libraries
- shared versus not - why? 
- static versus dynamic
  static - maybe slightly faster (don't need to link when running/calling functions)
  dynamic - smaller, every program doesn't need that 800KB
          - version problems (compile on one machine, run on another) - compile and run on the same machine
- blast from the past - "Dll hell"* (com32.dll)
  * note that windows was shared memory until Windows 2000...

boot process
- key takeaway - who is in charge of the computer?
      	       	 whoever has some code in the first sector
		 of the boot device (i.e., whoever has
		 physical access to the computer when it
		 turns on).

This is cool, it is the way stuff works!
