As it states on the syllabus:

Each week (starting the 2nd or 3rd week of class) we will have student presentations. I will randomly schedule the individual presentation dates. The topic of the presentations should be a new or somewhat new mobile media technology (hardware, software or service) that relates to the previous topics in the class. The presentations should cover what the technology/service is, what is novel about it, how are people using it and so on.

Here are the dates for the individual presentations:

Mar 1: James H.
Mar 1: Nahla I.
Mar 8: Kharisa R.
Mar 29: Kun L.
Mar 29: Sara H.
Apr 5: Oleg P.
Apr 12: Rediet D.
Apr 19: Supatra L.
Apr 26: Wei-Chung L.

The code for the random student chooser:

String[] student = {
     "Kharisa R.",
     "Kun L.",
     "Nahla I.",
     "Oleg P.",
     "Rediet D.",
     "Sara H.",
     "Supatra L.",
     "Wei-Chung L.",
     "James H."
};

int[] choosen = new int[9];

void setup() {
  
  for (int c = 0; c < choosen.length; c++) {
    choosen[c] = -1; 
  }
  
  for (int i = 0; i < student.length; i++) {
    float choicef = random(0,9);
    int choice = floor(choicef);
    while (true) {
      boolean good = true;
      for (int c = 0; c < choosen.length && good; c++) {
        if (choosen[c] == choice) {
          good = false;
        }    
      }
      if (good) {
        break;
      } else {
        choicef = random(0,9);
        choice = floor(choicef);
      }
    }

    choosen[i] = choice;
    println("" + i + ": " + student[choice] + " " + choice + " " + choicef);
  }
  println("Done");
}
