Inscrutable

Episode #635 April, 3, 2021 Computers are inscrutable. They are so complex. They cannot be known in whole. Yet we interact with them in nearly every aspect of our lives. https://www.youtube.com/watch?v=ebst8wY_320 With computer hardware there are certain scrutinies that assure that it is functioning as manufactured. Most of the time the hardware has not failed. Almost always a computer malfunctions due to software. Software malfunctions can be scrutinized for the following: Misconfigured settings. Damaged preference files. Incompatible applications. Demands of a too advanced operation system. Damaged source code. Incorrect permissions. Inscrutable problem Scrutinies of software are: Misconfigured settings. The settings...

Vis Viva

Episode #634 March 27, 2021 The total energy of an isolated system remains constant over time. — The Law of Conservation of energy https://www.youtube.com/watch?v=Pbg6CF4kJU8 This idea was described by Galileo in observations of the conversion of potential energy to kinetic energy, such as in the motion of a pendulum. Gottfried Wilhelm Leibniz refined this idea of conservation calling it “vis viva” (living force). Emilie du Châtelet expanded on Galileo and Leibniz’s ideas in the notes of her Latin to French translation of Newton’s “Principia.” She suggests that there can be no perpetual motion machine because a system requires energy input...

Upside Down

Episode #633 March 20, 2021 My skydiving guru told me, “There is no up in skydiving.” This double entendre observes that during free fall you are always going down with gravity.  It also speaks to the fact that every body position is correct. https://www.youtube.com/watch?v=cq8k-ZbsXDI Belly to earth, back to earth, standing or head down there is no up and no down, only stability. Relative to each other, skydivers are hovering. Position is always assessed relative to the observer in free fall.  If a diver flies past a formation he is said to be sinking. If a fellow skydiver observes you...

Forgiveness

Episode #632 March 13, 2021 “You have heard that it was said, "An eye for an eye and a tooth for a tooth." But I say to you, Do not resist the one who is evil. But if anyone slaps you on the right cheek, turn to him the other also.” — Jesus Christ, Bible (Matthew 5:38) https://www.youtube.com/watch?v=gCra2GifbcY Difficult advice. How can you bring yourself to forgive another? i have four ways: Love someone anyway. Agree to disagree. Walk away. Listen and engage with added fervor. In computing i have employed all of the above. Sometimes Apple “improves” an operating...

Efficiency

Episode #631 March 6, 2021 We like things to be efficient and to do things with efficiency. Efficiency saves energy, time, money and effort. https://www.youtube.com/watch?v=NbxqtbqyoRk Efficiency is a tool used to enhance a process. It is not an end result or a goal. When doing repetitive operations in a project i have used different approaches. SUBSYSTEM APPROACH: When building a composite graphic: Find the clip art. Edit the art. Store the modified image. Repeat for all clip art elements. Assemble the elements. Refine the final graphic. https://www.youtube.com/watch?v=sjAZGUcjrP8 CONTINUOUS IMPROVEMENT APPROACH: When building a composite graphic: Find the clip art. Edit...

Entropy

  Episode #630 February 27, 2021 Entropy is a randomness that is opposite of all we know and love. https://www.youtube.com/watch?v=tH2w6Oxx0kQ EVERYTHING IN THE UNIVERSE IS CONSTANT: The total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed. — First law of thermodynamics DISORDER IS THE GOAL OF MAXIMUM RANDOMNESS: Entropy (the degree of randomness) always increases with time. — Second law of thermodynamics ALL THINGS SEEK EQUILIBRIUM: A system's entropy approaches a constant value as its temperature approaches absolute zero. — Third law of thermodynamics:  ...
