Teaching Load Credit Computation

(Notes from Prof. Marge Paterno)
In summary:
      * Course credits (CC) for labs is 1.0 only (to be used for column 8 only)
        while Teaching Load Credits (TLC) for labs is 1.5 (to be used for the
        last column)
      * CC is equal to TLC in the case of lectures, lect/discussion classes and
        SP
      * For the last column, apply the multipliers on the Teaching Load Credits
        (TLC) rather than on Course Credits (CC).

*For column #8 for COURSE CREDITS (CC) without multipliers:
                           Lab: CC = 1.0
                Lect (2hrs/wk): CC = 2.0
     Lect/Discussion (3hrs/wk): CC = 3.0
              CMSC 190 1 unit : CC = 1.0
              CMSC 190 2 units: CC = 2.0

*For column #10 (last column) for TEACHING LOAD CREDITS with 
MULTIPLIERS
(TLCM):

     STEP 1: Determine TEACHING LOAD CREDITS w/o multipliers (TLC):
                           Lab: TLC = 1.5
                Lect (2hrs/wk): TLC = 2.0
     Lect/Discussion (3hrs/wk): TLC = 3.0
              CMSC 190 1 unit : TLC = 1.0
              CMSC 190 2 units: TLC = 2.0

     STEP 2: Apply corresponding multiplier to TLC to obtain TLCM:

       *** For UNDERGRAD courses:
           Lab class (any number of students):
             TLCM = TLC (i.e., no multiplier)

           Lect (2hrs/wk) or Lect/Discussion (3hrs/wk):
             # of students <=40:  TLCM = TLC
             # of students  >40:  TLCM = TLC*[(# of students - 40)/120 + 1]
            [# of students >160:  TLCM = TLC*2.0]

           For CMSC 190
             TLCM = TLC*(# of students)*(0.5/3)

            // Hence, for 190(1 unit) : TLCM = n/2 * 1/3, maximum of 3 units
            //        for 190(2 units): TLCM = n/2 * 2/3, maximum of 3 units

           For IT 1 Lecture only (if # of students >= 25)
             multiply TLCM further by 1.33  // multiplier for GE lecture courses

       *** For GRAD courses:
           Lect or Lect/Discussion or Lab
             # of students <= 4:        TLCM = TLC
             # of students >4 and <= 9: TLCM = TLC*1.25
             # of students >9:          TLCM = TLC*1.5

Disable SSH login, allow FTP in Ubuntu

In our IT 210 class, we need students to be able to upload files to a web server using FTP but disable SSH login to the server. To do this in Ubuntu, edit

/etc/ssh/sshd_config

and add the line

Then restart SSH using

$sudo /etc/init.d/ssh restart
