Yesterday on a visit to Lincoln, I came across this highly informative memorial to one of the cityโ€™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;

It's interesting to think about the conjunction there.

Most people would write "or". A quick check of several authorities finds them also suggesting "and" & saying that the "n't" carries over.

But I'd have my hardware engineer passport revoked if I didn't read "or" as meaning that we only need disallow you from running with scissors to make the required condition true; & think that a "nor" gate must be employed to ensure no politics. (-:

Boolean algebra, my nemesis! We meet again!

I'm going to tutor in Boolean algebra in about 30 minutes.

Actually, it is not a nemesis. Boolean algebra is the one "algebra" that I would have been able to tutor last year before I started refreshing my memory of the other types of algebra. I never really ceased using it.

Ask me to factor a polynomial last year, however, and you would have gotten a blank stare. The last time I did any of that was over 30 years ago. ๐Ÿ˜ฌ

(Happy to report that I took care of refreshing my memory.)

Something I've been doing lately in terms of layout. Based on the DRY switching concept explained in this series of articles from over half a decade ago css-tricks.com/dry-switching-w

body {
	/* --_vw0 is initially fallback of undeclared --vw0, 1 */
	--_vw0: var(--vw0, 1);
	/* so --_vw1 is 1 - 1 = 0 */
	--_vw1: var(--vw1, calc(1 - var(--_vw0)));
	/* and --_vw2 is 1 - (1 + 0) = 0 */
	--_vw2: var(--vw2, calc(1 - (var(--_vw0) + var(--_vw1))));
	
	/* above 21rem, --_vw0 becomes 1, 
	 * --_vw1 becomes 1 - 0 = 1, 
	 * while --_vw2 is 1 - (0 + 1) = 0 */
	@media (min-width: 21rem) { --vw0: 0 }
	/* but this is only valid up until 31 em, above which
	 * --_vw0 remains 0, but --_vw1 also switches to 0
	 * which makes --_vw2 become 1 - (0 + 0) = 1 */
	@media (min-width: 31rem) { --vw1: 0 }
}

/* then use the viewport CSS vars to compute properties like
 * grid-template, grid-area, 
 * align-self, align-content, justify-self, justify-content, 
 * margin, border, padding, width, height, 
 * aspect-ratio, transform, font-size, line-height, 
 * background-*, color, mask-*, 
 * box-shadow, text-shadow, opacity, filter, clip-path, 
 * text-align, text-indent, letter-spacing, word-spacing, 
 * and so on... for various elements on the page, for ex: */
button {
  /* spans 1 column, except for the narrowest case */
  grid-column-end: span calc(1 + var(--_vw0));
  /* in the middle when it occupies two columns */
  justify-self: var(--vw0, center);
  /* increase padding above 21rem viewport width */
  padding: calc((1 + .25*var(--_vw1))*1em);
}

P vs. NP: The Biggest #Puzzle in #ComputerScience

"Are there limits to what #Computers can do? How complex is too complex for #Computation? The question of how hard a problem is to solve lies at the heart of an important field of computer science called #ComputationalComplexity."

I always start the day with a daily ribute so as to or the memories of those who o have touched my life.

("To or" above should be understood the boolean way: one memory OR another memory, etc.)

Built an XOR gate in minecraft today to help my 9yo have two levers both able to control the same door. Not going to lie, it was fun. Iโ€™m already planning in my head how to build a ripple carry adder, and attempting to teach binary with it. #minecraft #BooleanLogic

Understanding AI through the use of expressive Boolean formulas

Hashtags: Summery: The rapid growth of artificial intelligence (AI) and machine learning applications in various industries has raised concerns about the complexity and lack of transparency in these systems. In fields like finance and medicine, where regulations and best practices require explainability, the current black box algorithms used in AI canโ€ฆ

You can't have cruel AND unusual punishment, So if it's cruel but you do it all the time that makes it cruel and usual, so then we're good right?
