Three-Valued Logic: AND - OR With NULL?!

SQL has THREE truth values: TRUE, FALSE, and UNKNOWN (NULL)! AND/OR with NULL creates logic that breaks everything! Watch!

Any and All Functions: Boolean Logic SHORTCUTS!

Python's any() and all() vs PHP's loops - which is more elegant? This changes EVERYTHING!

AND/OR With NULL Breaks Logic!

SQL boolean logic with NULL creates chaos! AND/OR operations with NULL give results that make NO sense. This is why queries fail! Watch now!

I just published a post on an interesting MSc thesis I supervised. Arvid Rydberg and Selina Sand Engberg took on the computational challenge of level-p-complexity (D_p(f)) of Boolean functions.

They optimised the algorithms using hash-consing & normalisation, and developed tools for exact calculations using algebraic numbers.

2B Or Not 2B? 🤔
Boolean logic meets Shakespeare.
if (2b || !2b) return "That is the question."

Yesterday on a visit to Lincoln, I came across this highly informative memorial to one of the city’s most distinguished sons, the mathematician George Boole - as in Boolean logic/algebra - described here as the grandfather of the digital age.

In all of the computer programmer jokes about trick or treat, I have yet to see "trick implies treat".

Or clocked logic, come to that.

if (rising_edge(november)) then
usa <= trick or treat;
end if;
