       CAREERS AND INDUSTRY IMPACT

What are some ways to help programmers?

   Better error messages
   Help them write better (e.g., more correct) code
   Faster tools
   Better optimization


           TOOLS NEEDED?

If a company created a new computer,
  what systems software would they need?

  BIOS or boot loader
  assembler
  compiler (maybe for C)
  OS
  linker and (relocating) loader
  libraries


What should they write first?
