Just took out a Laser on Westlake. Did some match sailing. The most part, it was just cruising around.

Notes

Sort of swelly (yes that is a technical term). Light winds. Single handed again.

There is no such thing as social distancing on a J/70. It is single handed or not at all. As one sailor said, it is BYOB (bring your own boat).

I was going to take Escape out of the ocean, but weather was nice. Good personal skill building since I had to do all tasks myself. As a boat owner/skipper, it is important to be able to do it all. This is making realise how much I depend on my crew.

Notes

With the COVID-19 (Wuhan Virus). Sailing may be over. Except for some very small boats such as harbors, lasers, RSs it is hard to do social distancing.

As I tell my crew, unless you are willing to get cozy, you have no business being on a J/70 while racing.

What was good about this sail was a renewed appreactiation for seamanship, expecting perfection in rigging, boat trim.

I brought up the topic of rigging. I made too mistakes. I did not put the backstay trim under the traverler. Also, the starbord jib sheet (yes, I know the jib sheet is continuous) went throught the rachet block the wrong way.

Who sailed or my position on the vessel

Just me! Single handed the boat.

Race date: March 11, 2020 The GoPro stopped before the race was over. This was our last race before the COVID19 rules stopped all organized sailing in Santa Barbara. Very light air still fun.

Part of my work is writing functions that test if a user is part of a population (set math) The database I work with in the grand scheme is not particular large, but large in its own right. Some rows can be in the millions.

Being me, instead of doing real work, plus having the experience of a Moodle plugin designer who’s module would crash computers and tell me that it worked for him on his laptop, I looked up how to produce a function that is efficient.. I have found two ways to do this. One from stackoverflow, the other method that is used a lot in Ellucian Banner.

I am going to list a function that I wrote in both ways. The logic suited the need of my employer.

StackOverflow method:

FUNCTION is_enrolled (pin_pidm  SATURN.sfrstcr.sfrstcr_pidm%TYPE) RETURN VARCHAR2 AS
   l_count NUMBER;
BEGIN
select count(1) into l_count

        FROM sfrstcr
        INNER JOIN stvrsts ON sfrstcr_rsts_code = stvrsts_code
                WHERE sfrstcr_term_code in (
          SELECT stvterm_code from stvterm where stvterm_code <> '999999' AND stvterm_end_date >= SYSDATE)
          and sfrstcr_pidm = pin_pidm;
        IF l_count > 0
        THEN
          RETURN 'Y';
        ELSE
          RETURN 'N';
        END IF;

END is_enrolled;

Banner Method:

-- Ellucian prefers to return boolian, I need to return (Y/N). They also like cursors
FUNCTION is_enrolled (pin_pidm  SATURN.sfrstcr.sfrstcr_pidm%TYPE) RETURN VARCHAR2 IS
   student_found VARCHAR2(1);
   student_exists VARCHAR2(1);
   CURSOR found_student_c
   IS
        select 'X'
                        FROM sfrstcr
                        INNER JOIN stvrsts ON sfrstcr_rsts_code = stvrsts_code
                        WHERE sfrstcr_term_code in (
                                SELECT stvterm_code from stvterm where stvterm_code <> '999999' AND stvterm_end_date >= SYSDATE)
                        and sfrstcr_pidm = pin_pidm;
BEGIN
        OPEN found_student_c;
        FETCH found_student_c INTO student_found;
        CLOSE found_student_c;
        IF student_found = "X" THEN
        THEN
          student_exists := 'Y';
        ELSE
          student_exists := 'N';
        END IF;
        RETURN student_exists;
END is_enrolled;

Personally, I am not sure which is better, but, I might as well do it the Banner way, instead of always trying to reinvent the wheel or borrow some else's wheel.
