Happy π day

Why are the buildings so hot?

• AFAIK, steam vs. chilled water pipes
• Good news: a cold front comes through today...

Some background on big-endian vs. little-endian

• Why: because you need big-vs-little endian for WAV files

• What: 16-bit integers (short, or short int) and 32-bit integers (int, or long int) are stored differently on
  • big endian machines such as strauss, vs
  • little endian machines such as Intel-based PCs (regardless of whether running Windows, or OSs such as Linux)
• How: we'll take the initials.cc program from http://www.udel.edu/CIS/181h/pconrad/06S/lect/02.28/initials.cc and show how the result is different on an Intel PC (running cygwin) vs. running on Strauss

Then: Our friend the sine wave

walk through the background for lab05 (which is lab04b from last fall's regular 181) and proj1 (which is proj1b from last fall's regular 181)
